Watch NOW! Immobilizer Bypass No Special Tools Needed Real
Вставка
- Опубліковано 5 жов 2024
- Stumbled on this trick. Had a customer come in with problems and found the ecu to be bad. This car is equipped from factory with an immobilizer system. Many cars around this year will have the same. Simply switching ecu's will no longer work. The code in the key and the ecu have to match in order to start the car. I'm going to show you a way how to go around that for testing purposes. You still need your original key(s) and the original matching ECU. It will not work without those. This will continue to work until you either unplug the ecu, unhook the main battery, unhook the main relay(s) or if your battery runs dead. If those things happened the security light will blink again and won't let you start the car until you do the same trick or unless you reprogram the ecu and/or keys

Great video 👊😎👊
Thank you! Thank you for the love! I love what you do on your channel! ✊🏼
U stupid
Smart idea, so you need a second Electronic Control Unit to do that
I really appreciate how well you did everything you did from the very beginning in describing the problem, to explaining what you were going to do and then explaining what you were doing while at the same time performing the work needing to be done, with one hand no less AND filming it as well as you did with the other hand all at the same time. Fantastic!
Maybe you could provide a little advice for me after hearing my sad tale of woe.
I have a 2003 Volvo S40 that isn't getting any power to the fuel pump and like many people here I don't want to pour a bunch of money into it at a dealership where the part that I can buy online for $59 is sold by the dealership for over $700 (not to put to fine a point on it but they also are very proprietary with their software fixes in that outside a dealership it's difficult to find anyone who has the capacity to work on these things in a software sense) and of course you can't bring your own part. Add the expense of towing and then having them holding you over a barrel once there isn't an ideal situation in my eyes. I cannot start the vehicle although it does crank. I was wondering what advice you would give me. I did get a little friendly advice from the parts guy at the dealership who suggested it might be an issue with my "immobilizer" and not the ECU or CEM. Would really appreciate your advising as best you can what you'd do in my circumstance and if you need additional information, I'd be more than happy to provide it. Kindest Regards! Joe

Peter,
I having an immobilizer issue I believe with my 98 Lexus gs400. The car will start most of the time with no problem but sometimes when I try to start it, it will crank then start the motor, then will run for less than a second then dies, then I see the key light blinking on the dash. Next, Any attempts to restart the car only cranks the motor over with the key light blinking. After a few minutes with random attempts to restart, the car eventually starts again. I bought the car used so i'm not sure if I have the original key but I'm current using a aftermarket key/reprogrammed with no problems for over a year until now, and I also tried the second aftermarket reprogrammed key with the same problem. I have not tested the original key that came with the car (its an intermittent problem need to test up to 2 weeks to see problems reoccur) but since both aftermarket reprogrammed key have problems I do not think it's the transponder in the key problem. What do you think? Thanks in advance.
sorry it took so long to reply. i would start with using your original key that came with the car since it will not cost you any money just a little time. it will also rule out the question if its the aftermarket keys that are doing it or not
It's all good I know you are a busy man. Recently, I have been using the original key with the car for over 2+ weeks now without a problem. What puzzles me is that I have been using the aftermarket keys without a problem for over a year until now. Can it possibly be the receiver amplifier or the key ring coil problem? For now I'll just leave it as is, and use my aftermarket keys for backup; just hope I never loose the original. :) Thanks for your help!
Great video please could you explain little bit about Toyota Mark 2 1JZ
Hello Revved,
first thing to understand the functionality of immobilizer. immobilizer works only when you turn on ignition, if security code match at turning on point with the ECU code then everything keep working until you turn off the ignition.
keep in mind ignition on doesn't mean you started your engine, ignition means engine can be start but you have to self start it by rotating the key one step ahead.
if you turn on ignition with original key then its no matter you put anther key or change ECU with other one.
that's not the bypass.
Brother my car starts and off suddenly after few seconds
How to fix it please suggest me
@@MTaha-je4yj what make and model your car is. And check is there any security li8 in the meter cluster or if its not avaiable. Then check your engine li8, is it blinking repeatly when you turn on ignition ?
My friend one question, i bought an used ECU, same make and model can i bypass the immobilizer, it cranks and also sounds like it wants to star but then stops, by the way my car is a 2001 hyundai Santa Fe 2.4 liter Manuel transmission, made in Korea, i know for sure my original ECU it's bad, because it does no communicate with my scanner, and the used one that i bought it does communicate with my scanners so that gives me hope to start my car, can you help me buddy. Thanks in advance...
@@LuisMartinez-fr9gq Brother, this Hyundai Santa has Immobilizer Code in 2 places .1 in ECU and second in Immobiliser device, your Key and immobilizer code are the same as it was original, but due to change of ECU, now your ECU cannot recognize the original code because it has other code in it.
you just need a Good Machanic who can reprogram its ECU to match your Immobilizer code.
it will only cost $30 - $35 in Pakistan , but in your country, i can't say anything.
GOOD LUCK.
@@talharafique8913 Hello Buddy, thank you for your advice and knowledge, i will check this with a mechanic, I'm glad you told me this i thought it only has one immobilizer on the ECU, but now i know. One question, do you think it's a way to bypass the new ECU Buddy.
What a nice trick you made! Excellent. If you dig behind a little bit, you were be able to locate and replace the key code IC from the old ECU to the new replacement ECU and make it a permanent solution without re-flashing and reprogramming the immobilizer and ECU after replacement. Regards,
+LearningZone how can I replace the ic key code (ic900) from the old to the new without reflasing the ecu?
+Matan Rotem You can reprogram or swap the key code IC form older ECU to newer ECU.

I enjoyed the video. I’m curious will this trick work on a 2002 Pontiac Grand Prix
Finally a video that's straight on point and worked. Thank You sir
You sure lost me there, I dint know which ECU you were using, though it is very noble of you to share some information for free to be used by us to make money
Sorry I lost you on that. The original ecu was still bolted into the car. The one hanging was the used ecu. I don't mind giving free info especially if it helps people who like to do things themselves or just don't have the extra money to pay someone else to do it. Of course people can always donate to me 😉
Peter Nguyen hello i hope u can help me i have 2013 sonata it has a code thingy on it i didnt have money to pay the pmyt this week i had pneumonia and the car place they r pretty mean..but i really would like to get to the store im n need of things but without a code the car wont start.
it is illegal (federal law) to bypass a lenders lockout device. No locksmith or anyone else will help you!!
Suggestion, do not agree to a lockout with a lender. Those types are HOPING that you fail to pay so the can seize and resell the vehicle over and over again.
I’m just curious if you cut all the wires and spliced them together (matching the colors) will it work too.
Yes
Hi there, I have a 1991 cressida, 7mx83, and when the 7m blew the head, I put a 1jz vvti 171, which has an immobilizer.
what do u recommend to get past the immobilizer?
I had a quote for 1000$! bit steep, so looking for an alternative, hope yoiu can help..
I like the no messing around, straight to the point style you have.. cheers
I thought those didn’t have immobilizers in Japan. Best route would be a stand alone computer for yours especially if your going to tune it or add upgrades to it!
So to hack immo, you need à working ECU and a working key ? 😅😜
Alot of different types of hacks in the world require some peice of hardware in one way or another. If you're not reverse engineering the software you're usually reverse engineering the hardware
@@thatdamnmanhd7984 true yes
Or just disassemble the ecu, read the chip with xprog and use something like abrites to write immo data in to the new key.
You can also remove the EEPROM from the old ECU and fit it to the new ECU
And how can i do this?
How long does the effect last ? Does it matter if the "new" one was flashed ? Will this same trick work with all toyota type one ecus ? And, last question, how did you learn this ?
Would swapping eeproms from original ECU to a new replacement ECU work with the original keys?
part numbers are matching btw
Nice job
Thank you 🙏🏻
Sir Lexus 250 2015 model can you explain immobilizer Bypass
You know how I can bypass immobilizer on my 2004 Mazda Miata ? Intermittent not reading my key. Been stuck a couple of times. Don’t have the funds to get new ones. Please help if you can or point me to where I can get help. Thanks
Try seeing if you can replace just the immobilizer reader. Sometimes it’s the reader not doings it’s job and not the key. I’ve done it multiple times on Honda’s but not sure if you can do it with Mazda. Call your local Mazda to see if you need to program the reader as well. Good luck
I was having problems with my 99 accord ecu. All i did was swap out immobilizer chip. Works fine.
Where is the chip located
Ok well there is a chip in the key that is read by the immobilizer transponder And sent to the ECU there is also a chip in the ecu that you can remove or buy a bypass chip and replace
i have a 2003 avalon , security light flashing, it wont start , i bought the car with a metal key with no chip , will programming a key solve the problem?
Will your key they get reprogrammed by itself to work with new ecu?
No you must get it programmed
Hi,
Should we address you as Mr. ChickenDinner? ;-)
You seem knowledgeable and fair minded (a rare combination these days) so I'd like to see what you have to say about the following puzzle...
I have a 2001 Explorer that a kid (now in the army) had major surgery done on. It now has a 2006 Explorer engine (professionally installed) and a standard tranny where the automatic once was. He told his Dad (who just wanted it out of his driveway) that it needs a new GEM/BCM but I don't want to start just throwing parts at it.
The "theft" light is on before I even put the key in and I'm not even certain it's a properly coded key.
When I tried jumping the starter relay, all that happened was the heater fan came on.
It probably is looking for the neutral safety switch as well.
Lotsa fun, huh??
I've been learning about bypasses and your ECU trick sounds promising.
Do you have any suggestions/hunches???
Thanks much,
BE
+Liberallez sounds like you have a mess on your hands! ok i have a question for you. What ECU is it using? we can start from there. i have done a few automatic to manual conversions and in most cases its still possible to use the automatic ecu/ecm/pcm etc.. what you have to do in most cases is to fool the car is in Park (to start the car and to take the key out of the ign). thanks for watching and commenting on the video and i hope i can help you sort out your issues on the explorer

+NguyenerWinner ChickenDinner
Hi,
After going over the shop manual, the best I can figure is that this car doesn't have an actual ECU.
It has a bunch of different modules like the power train module, anti-theft/immobilizer, etc. and it has what is referred to as a "multi-function module" which is also called the Generic Electronic Module but the list of it's functions doesn't seem to include anything but body stuff like wipers, windows, etc.
That module's number is 1L5T-14B205-BE. There is also a large letter B near that number.
Does all that tell you anything?
Thanks,
BE
PCM(powertrain control module) would be the one your going to look for. trying to see if they changed that out or if its still the original one that came with the suv. If they used the original engine wiring harness and is still using the original PCM and assuming it all the plugs plug together(or modified to work) correctly, it should start up or at least let you crank it over. You might want to try and find the neutral safety switch (its the electronic piece that the shifter rod is connected to on the transmission) on the automatic transmission (take it off and plug it on the harness on the car) and switch the switch to the park position.
+NguyenerWinner ChickenDinner
Very interesting...thanks.
I'll get back to you as soon as I have something new to report.

Great video ! Unfortunately didn’t work on a 2004 Highlander. 😔
Thank you 🙏🏻. Dang sorry it didn’t work for yours
I have a 2001 Toyota Avalon got a replacement used one and did exactly like you did and the security light keeps flashing will not crank any suggestions please
Great video did you know where can reprogram ecu on 2005 Honda CR-V and how much they charge I hope you can answer my questions thank you
I you have made an impression if that is real very good trick to not need to do reflahs the computer
Still need to re-flash to make it permanent. It’s only for testing
On vehicles with the immobilizer on the instrument cluster, do you still need to program the ecu?
I replaced the ignition lock and key cylinder switch on my 98 Avalon, but it won't start. Do I have to program/code it to get the car to start? The new one is in and the old one is out.
+DadSkip if you still have the old key, i would take the new ignition lock and the old key to a locksmith to match the old keys to the new lock. that way you can use your old keys that has the programmed chip in it. its the easier approach and you'll only need one key to open the door and start it.

Is this trick sir accurate to do this in 2006 HI-ACE I replace the old one computer and change the 2ndhand computer ..still cranking but will not start .is this accurate to do this trick sir..thank you
If you have a working key and a good ecu just switch out the 93c56 from the bad ecu problem would be fixed no need for the unplug replug b/s bypass
Hello friend, do you know if the 2001 Hyundai Santa Fe 2.4 liter has the same chip 93C56. TO switch it to my used ECU that i just bought??? Thanks in advance...
I have a 2009 Hyundai Tuscon my imboilzer light doesn’t come and won’t start I get a 0560 code and 1676 if I have replace my mobilizer would I just need another Ecu I have both keys
how old is your battery? sometimes when your vehicles battery does not have sufficient power i could trigger those codes on your Tucson. if it is fairly old i would try and unhook it have it fully charged and see if that helps. you might have to clear your codes via a scanner as well. if you do end up replacing the immobilizer piece, you would need to get it reprogrammed to your keys and or ecu.
Thanks for the vid. I have a 2000 Avalon that is running rich on bank 2, misfires like crazy. no CEL on, scanned it seen fuel trim way up bank one,shut the computer out ,in service mode engine corrects its self for the most part..Does this sound like symptoms of a bad ECU?
+TheOwen1974 thanks for watching!! I would check the vvt oil control valve on bank 2(front of car if you didn't know already). with that being bad could make the whole bank misfire. Seen plenty of those engines with that problem. Check that first, its easy to take off, just a plug and one 10mm bolt.

damn.. that's smart
2002 Chevy Impala that will not start. Dashboard will come on but the key will not turn to the start position. Car ran and started fine all day but now it wont start. We changed the ignition switch and cylinder but that didn't work.
+alysia Porter with the new cylinder it should turn all the way. Did you check for any debris left in there from the old cylinder before putting new one? Something could be blocking it from turning all the way. Is the car all the way in park? if it is try putting it in neutral if you can, to see if that will let you start the car, if it does than you either need to replace your Neutral safety switch, adjust it or the shift cable could be bad as well. let me know as much detail as possible because these things are really hard to diagnose without me physically checking it myself
thanks
good video, my question is will this work for say an rsx? does the ecu have to be a direct replacement? do you have to swap the wires on start every time? could you run both ecu's plugged in?
Thanks for the information..
No problem

Hey I just Recently replace the key ignition cylinder do you think if I put the ECU from the same vehicle that I took the key from it will go away
Recently I lost my 01 VW Jetta 2.0l key so what I did was I replaced he cylinder key lock and put one from a 2001 VW Jetta vr6 that had with the key and I replaced the computer as well or the ecm and once I went to try and turn it on the immbolizer light came on and doesn’t want to turn on...? Any help
Jorge Salas Thank you so much for watching the video! If you haven’t yet Please LIKE and SUBSCRIBE! Had a similar situation happen to me at my shop, someone stole a bunch of keys and I was left with replacing all the keys missing. I had to call a mobile locksmith come out and re program new keys. Did your key and ecm also come with the immobilized ring(reader)? Sometimes you’ll need that too
So, I tried this on my 04 Toyota Sienna. It did not work. I think Toyota hates people fixing things themselves, so they make it impossible for us. Thank you anyway for this video.
sorry it didn't work for you and thank you for watching

awesume !! does it last after you shot down and take the key out ??
.Thanks for commenting!! As far as i know, the trick will work even if you start and turn on the car over and over again. Just don't remove the computer, take battery off or take out the ecu fuse!
On a lexus is200 2001-2 year, this it not work.i tried a lot of times, and no luck...When plug into the old ecu, security light stop blink(with key on) then when back the connector to the new ecu, it start blink again, and to starting engine..

+thomas edwards unfortunately i have tried this and it doesn't work on Honda/Acura's . I tried this on an Acura MDX and they share the same immobilizer system. You have to get it programmed. i have a few questions for you, how many keys did they give you and do you still have the other keys (original ones) on the key ring next to the key that starts the car?
+Peter “LikesToFixIt” Nguyen Hi Peter first i should say this vehicle never started after adding components that were worn out the last was the ignition switch that was sticking so i decided to change the switch with key and i got a good deal and they added the ECU tested good they said both the old and replaced ECU's only had one key and they were never on a key ring together ever. Seems like everything is working it's just the immo green key flashes constantly. please ask me more question i really need help. thanks peter for responding.
+thomas edwards sorry took long to reply hopefully you have it sorted out by now. Seems like the key needs to be re-synced with the immobilizer system

So let me be the first to tell you thanks you for showing us this!

Hello everyone.
I hav a problem with my 2001 honda civic vtec 1.7 eu.
It was driving fine and ignition was faulty n as i was driving some smoke came out from the engine bay.
I stoped on the side of the road n tried to switch off the engine but the ignition systerm was faulty n couldn't go off until i popped up the hood n removed one terminal n the car switched off.
Fixed the starter n put it back, but now ever since that time it cranks but doesn't start n the green key is flashing on the dashboard..
Auto technicians came diagnosed the car n couldn't find any faults.
Has anyone faced this issue before ?
I was wondering if this would work for an acura rsx type s 05? Possibly?
there has to be away without doing that using the system to remove that feature altogether and everytime i look on web it keeps going to reset info when i really i just want to see if its possible to not bypass but remove it altogether from the start in programming
I'm looking for that too. I want to completely get rid of the pats because I'm tired of 200 dollar keys and the alarm. Somebody destroyed my ignition and module so now i cant even start my van. Ford referred me to car toys. People act like its some sacred ancient knowledge.
For how long can you drive your car like this
My Acura 2004 rl immobilizer is bad according to Acura dealership they wanted to replace it for a huge amount. Any suggestions for me?
Is it an intermittent issue? Sometimes it starts and sometimes it doesn’t? Is the green key still flashing with the ignition all the way on?
Revved Up Knowledge thanks for replying. I lost my keys they told me my immobilizer is bad which need to replace in order for them to make and program the new keys. I have no ideas if is the intermittent issues. For now that what I been told in order to have the car running.
Did they say it was the module or the reader that was bad or maybe both?
Well in any case you can buy a used set of Keys with the matching ECU(computer), with ignition switch and immobilizer module used on eBay and you can either change them all out yourself or pay someone to do it. I saw a used set for around $300. You can also remove all your door locks and have a locksmith re-key the locks to match your new set of keys as well.
Revved Up Knowledge they only told me my immobilizer is bad. Ohh man used keys with ecu then replace all doors lock seems so much money might be the same amount of money the dealership is asking? Anyway sir thank you for replying appreciate it!

Has anyone tried this on a 2002 Lexus GS 300 or knows if this may work on that kind of car as well?
Will this work on 1999 solara
Yes It should but you need a still working original ECU with matching key to perform this test

+TheOwen1974 does the original ecu work still or completely dead?
+Peter “LikesToFixIt” Nguyen Again , Thank you for the help..original ecu still works ,a friend of mine has a Snap-on Modis handheld, he isolated the ocv and can trigger it on and off , ocv's seem to be fine, and were new last year along with the o2 sensors. when it warms up ,it starts idle searching , and dumping fuel into bank 2. if we shut the ecu out and put it in service mode it straightens out and the misfire goes away. originally I thought the vvt gear may be sludged or worn at the locking pin but now thinking its the ecu. the kicker is no codes..sorry to keep asking questions, but you seem to be the only guy (on the tube)who knows what you're talking about..
+TheOwen1974 hmm this is tough without me physically checking the car. I had a similar situation happen to my mother in laws RX300. Ran flawlessly before warmed up, but when fully warmed up it would run way under powered and if i feather the throttle the idle would surge up and down( no check light on or anything). Drove around making the engine surge up and down till light came on. Checked it and codes came back as a bad OCV for bank 1. Changed bank 1 OCV and symptoms were gone. I checked the bad valve by running some current through it and it worked fine but in the car it wasn't working properly.
Try and run the car long enough while its idle searching so that the check light will come on. I don't think its a faulty ecu. wish i could physically check the car for you! let me know if this helps or not so i can try and help stil
On a 2001 Toyota RAV4 the engine starts fine , I’ve had to replace the computer because it damaged the transmission. I put new computer in and now engine only cranks but will not start. Funny thing is this RAV4 doesn’t have any theft deterent devices on it just one black head Toyota key NO security light on dash . Code is B2796 no comms with immobilizer . Now would all I need is to have a new key cut and programmed and if so what is it going to program if car it self has NO theft deterrent devices just the new computer?
I would go back and get another computer. Happened to one of my customers cars I did but luckily Toyota warrantied the one I bought.
Revved Up Knowledge yes sir I have another computer already being shipped to me, I explained to them the situation and they are saying they may have sent the computer with immobilizer integrated in ECU so now their sending one without hopefully that’ll be it thanks for your response much appreciated
Yea on my customers some short in the electrical system caused the immobilized system to activate itself. This was 5 months after the new computer was installed. All is well now with it so thank god!
Good luck!
Can it be left off?
I doubt I can do this on my Infiniti qx4 it only has 2 plugs
Hi how could I do this to a 2005 Toyota Solara 4 cylinder , swap my ECU but car won't turn over ?
i haven't tried with this year toyota but it might work. have you tried following this procedure?
What was the original ecu doing before you installed the used one? My 1998 avalon security light is blinking when I try to start the car and it won't start. Nothing is firing on the car.. If I buy a used ecu, will I be able to do what you did and get it started? Thanks so much if u have more information.
Hey Victor, thanks for watching!! The original ecu in this car was overheating and would die out after 10 minutes or so of the car being on. It would let me start again after 20-30 minutes after cooling down. It seems like your issue is your keys. The computer isn't recognizing the keys immobilizer code. You can have your keys reprogrammed at your local dealer or a locksmith company. Some shops have those programmers as well. Most high end diagnostic scanners will have that option too if you know anyone with a scanner. Let me know if i can help in any way!
Oh and buying a new/used computer and trying this trick won't work. Original needs to recognize keys first to dis engage the security
So my only option is to have the keys reprogrammed.....
Also, thanks for all the information....
yea either way you go you would need the keys reprogrammed. i would try to get them reprogrammed first before you order the used ecu. there are tons of mobile locksmiths that can do that at your place too so you dont have to tow. just be sure to ask if they still charge even if it doesnt work.
no problem if you have any questions car related i can try and give you my best advice.
Wish there was one for scion tc 2005
When you buy a car, buy a spare ECU aswell
Excellent
No kidding I do this with all vehicles and had to fly to Mexico just find one for a rolls Royce
Like we all have a spare controller around!
Pull a part
You go and get one, smart guy.. 🤓😐
but when you turn off the key and back to on immo will engage as normally
well that werks on dat vechicle , there are many with same thing but different color codes and connections. and if its not something your doing everyday you can maybe do damage to any other system . my thought.
Well I am kinda desperate so here goes, I have Toyota Yaris 99 and lost the keys. From what I read so far, Id have to replace whole ECU (which is not financially viable). Is there anyway to get this started without original keys? Is there any way to get Yaris 99 to start without original transporder?
you have to get new keys made and have a key company or the dealer sync your new keys with the car again
I'm hoping this works on my 98 Lexus ls400. I got a new ecu cause I think mines bad and got a used one with no keys so this will help. I'll post an update. I hope this works and your not pulling my chain lol
Update? Also have 98 ls400, keys all stolen. Have new cut keys, got fob programmed but not immobilizer
Hi Peter! I was thinking about purchasing a Toyota Avalon that was jump started incorrectly. The person who has the car says it has no spark or injector pulse.. He say he replaced the computer, but it still won't start.. How is the ECU supposed to be replaced? Also, is getting the car started going to be a challenge?
What year is the avalon and ask them if they still have the original ecu. When jumped incorrectly it shouldn't burn the ecu. Only thing that usually happens is the alternator or main fuse will blow before anything else. Should be a real easy fix. In the case that the ecu is damaged, replacing it will need to be synced to your car/immobilizer system with a Toyota dealer grade scan tool or one that can reprogram the computer. In my 10+ years of working I've never seen an ecu that got fried from jumping wrong =) and I've seen plenty of those wrongly jumped batteries
@@RevvedUpKnowledge Thank You for that bit of info. That is exactly what happen to my 2008 LS460. I got *key not detected*. this is push button ignition and not keyed. I will look for Alternator main fuse again, its the 30 amp square with window, it does seem intact and has continuity.......
Ordered a replacement ECM on line programd to my FOB with my VIN number but the car still does not crank or start, oh and the push button is only faintly lit, not green, just faint amber! I wish someone with same problems has a solutionn!!!!!!!!
hi! could this work the same way on my mazda demio from 1998?
Hello Dear,
My SEAT LEON 2014 1.2L TSI's ECM was damaged due to short in O2 sensors wiring, it's confirmed that my old ECM is faulty and I just bought another ECM from junk same car.
Now my car just started for 1-2 seconds and then turned off due to Immobilizer mismatch between second ECM and the car itself.
My question is which CHIP I need to replace between two ECMs to match Immobilizer system? which IC stored the Immobilizer code?
Or How can I program the new ECM in details?
Below ECM details:
printed outside on case of ECM: VW AG 04E 907 309 A
Control Module Part Number: 04E 906 016 C
HW: 04E 907 309 A
Appreciate your quick reply.
BR,
Would this work on Renault Clio 2001
