If you don't have 4 keys to program, you can exit the auto programming mode by pumping the brake pedal 5 times. Then the security light will start functioning like normal.
That’s for 4d chips not 4c, to turn of the light it needs four keys. With that said it won’t hurt anything with it blinking. But to turn it off you could use any glass 4c chip even if your friend has the same car you can stick it into the ignition and it will save it and not mess his key/car starting his car.
Great video. Online forums just tell you that the ECU is bad and needs replacing! I’ve just purchased an 1999 Lexus GS300. It only came with one aftermarket key and now it’s won’t start. Security light is blinking red. So think I’ll try this to clear all the previous keys coded in.
Hi Everyone. Clearing keys didn’t work. But my son found a work around. Here it is: 1. Try and start car once. 2. If it doesn’t start, turn ignition off and back on again. BUT do not try to start. 3. Wait 7 minutes. 4. Ignition off and on again. But this time try and start it. This worked for us. I suspect the 7 minute wait is an anti theft feature. But it times out.
FYI; Some Toyota's from early 2000's will exit the (virgin ECU) automatic registration/programming mode after pressing brake pedal 5 times within 15 seconds.
Binh, thanks so much for making this video. You really, really helped me. I was able to take notes from your video and Dr. Shock's and successfully programmed 4 keys. In my particular case it was on a 2001 Lexus LX470 but it had the same 16-bit eprom (IC900 on the board) and everything worked the same way. The trick was getting the USB driver to work on laptop and making sure the clip was making proper contact with the chip (R/W light on the CH341A).
For some reason I couldn’t get the programmer to read the chips. I was just switching from auto to manual I just desoldered the chips and switched them and worked out for me.
Hey Binh, I've been following your channel for 2 years now and you've been a great help on piecing together my w58 MK3 Manual swap in my 2002 IS300. I needed to ask you if a 2004-2005 manual ecu will work with a 2002 IS300. I know their are slight differences in the part numbers but I'm assuming 02-05 manual ecu should all work because the harness is the same. If you could give me a for sure answer that would awesome, because I plan on picking up the 2004 manaul ecu as my last part of the swap for only $100 without keys!
hey love your videos they help me a lot when it comes to my 99 gs300. what are the odds of you making a specific video on how to set up the programmer for dummies like me that dont understand wtf dr shock is saying lol
Would this process work on 2006 is250? This car has a separate immobiliser module (ID Code Box) that has an eeprom, so could you do the same on there instead of the ECU, and then perform the OBD pin short "handshake"?
Amazing video! I followed your instructions and got two masters and my valet working, but im having trouble programming the key fob to get the keyless entry working. The car is still in the programming mode (because is didnt have a third master for it to learn). Could that be the reason? Should i try again when the ecu gives up and goes back to normal?
Remotes are a different control module. I have a video on programming remotes. Posted last week. Immobilizer programming mode will exit if it doesn’t get all the keys.
Awesome detailed video. I have a Mercedes 190SL with 2007 Yaris drivetrain. This car was running with a regular non chip key but since I changed some of the wiring, now I get code B2799 (Immobilizer System). So I have no ignition or fuel. Is it possible to program this ecu to run with a regular key which does not have a chip?
Hi Binh. Thanks again for a great video. Love the channel. So I got a 2008 is250 a few weeks back, and it only came with one key. I’d like to use this eeprom method to Virginise the relevant ECU so I can add a used key I got my hands on. My question is, are you aware of how to do this same virginise process in an is250? I suspect it may not be the ECU that needs to be worked on, but the “smart box”, which I think is in the boot. Any thoughts?
I thank for the video it's really helpful. I'm in a situation now where I have 2 Toyota Cressidas (The last two generations), 3UZ-FE with 5-speed auto transmission and 3UZ FE with steptronic 6-speed transmission. We have the original engines' ECUs for each engine. We have also 1 extra ECU that comes with gas pedal, a key, contact. It's missing the immobilizer's ECU. What is the cheapest and fastest way to run these 2 engines please?
Thank for this information, but I have a question; can you delete the 900 completely for the ecu system? I have an 1996 an swapping in a 2005 engine with its ecu.
I heard if you program the ecu in Learn mode or virginized then unplug the immobilizer key reader any key will start and run the ecu (this has to be verified!) Lmk if this works please!

Please help.

I would like to know how to program the immobilizer that is in the dash so that the security light will go off and my vehicle will start right now it will not start and there is no one locally in my big city that knows how to program an immobilizer
Toyota Lexus would have to seed the ECU with an unlock from corp. usually they don’t like to do this. They’ll just make you buy a new $1,200 ECU plus a new $500 key which they can program easily out the box.
So this is a lot of work, I'm not experienced in this kind of thing and I don't wanna screw it up. Is it possible to pay a dealership or something to have this done or do I have to do this myself to run a manual ecu?
Hi, great video much appreciated. You mentioned video on how to set the CH341 for automobles, but I cannot find it. Do you have a link to this video please. Many thanks
hmmb interesting. Im in a situation where I only have a valet key programmed to the car, and I have a master key that is cut but not programmed to the car. and from what I know and have experienced is that you can only program new keys to a lexus using the pedal dance method when using a master key as the host key. the pedal dance method doesnt work with a valet key. I watched this video but im just not quite familiar or up to scratch with some of the terminology mentioned.
This is next level stuff. You are hacking the EEPROM to wipe it and telling the ECU it’s brand new and accept the fist three keys it sees as master and 4th as valet on the IS300. Probably same for most Lexus of this era.

Ultimately he got a key to turn on the dash, but couldn't unlock the immobiliser and actually start the car. I just wondered, after watching your video, if maybe we'd found a better - less expensive - solution. Thanks anyway. I'll keep digging.
Hey I have a Lexus key but the transponder chip is bad. Can I buy a new transponder chip, use my old key in the new case, and reset my immobilizer to match the new chips code?
the transponder needs to be programmed to the car. The chip is highly unlikely to go bad. Its a passive device that doesn't have any real "moving" parts or power.
@@TunerwithKids this seems like a massive oversight on lexus' part, the fact that the immobilizer can literally shut down your car but can still be reset if a thief has the know-how. i guess they didnt anticipate being able to hack it in 25 years

Hey, can you tell me if the virginize code works on an 01 IS300 ecu? The chip is the same and I've read the contents. The keys appear to be stored in a slightly different arrangement, but the virginize code matches up if I zero out the other cells. The cells with values that you didn't change to zeros match up, but I had to zero out additonal cells that didn't have values in the 02+ ecu chip. Let me know your thoughts on this.
Is the only thing that prevents another ECU from working in your vehicle is the immobilizer function and whether it will allow keys to work in the ignition? IOW, after this is done, the new ECU will work perfectly in the vehicle, right? Nothing else is necessary, right? I have an all keys lost situation on a USA Lexus RX300 and I'm going to see if an XTool D7 will program a new key without swapping out the ECU. If it doesn't work, I might be following this path.
Okay thank you, i got problem to read the epprom. The ic850 is connecting good and i can read, but i can’t connect to the ic900, i Cleared the pins but i still got problem

Hi Binh, I bought a used Rav4 from an auction with no keys available, do you think if I reset the keys to zeros as you’ve shown, I’ll be able to get the car to recognize a brand new key? Given that I don’t have any key for that car. I appreciate your help.
Hey Binh, great video! Are you still considering a video about setting up the CH341A programmer? I would greatly appreciate it! :) Greetings from Germany
Any idea if I would be able to program an aftermarket key fob? The OEM 2 button key fobbfor my Altezza is discontinued. Tempted to try and link a LEXUS key fob to it.
Should work, the key immobilizer is a “4c” chip used by many cars and brands. The remote portion is different computer and programs differently. Most all Toyota use the same frequency and chips.
Hey all, I was wondering if someone can help me out here. A long while ago, my ONLY key to my 2000 Lexus GS300 broke, and the chip inside went missing. I was able to retain the actual metal key part of it and the car started perfectly fine for a while. Just yesterday (3/31/23) I tried to start the car and it would not start. I began troubleshooting like normal and even went as far as replacing a fuel pump as the engine would crank but not fire up. However, i just noticed that the security light (the little car with the key symbol) is flashing even with the key inserted. I suspect the immobilizer is preventing me from starting the car now. I do have a blank key/transponder but obviously I cannot reprogram it normally without the master transponder. If I were to pull my own ECU out and viginize the immobilizer, would I be able to program the chip in the blank key? Thanks.
If you don't have 4 keys to program, you can exit the auto programming mode by pumping the brake pedal 5 times. Then the security light will start functioning like normal.
Turn the key on and off 5 times turns off the auto registration mode.
I tried this and it doesnt work, do you have more detailed instructions?
That’s for 4d chips not 4c, to turn of the light it needs four keys. With that said it won’t hurt anything with it blinking. But to turn it off you could use any glass 4c chip even if your friend has the same car you can stick it into the ignition and it will save it and not mess his key/car starting his car.

Not with any tool. If you do this, you can clone another ECU immobilizer. Or reset it to allow any key to be added.
In the hex labelled “Valet Key Lockout” change “FB” to “FC” and that should allow only three keys during programming not four.

Ultimately he got a key to turn on the dash, but couldn't unlock the immobiliser and actually start the car. I just wondered, after watching your video, if maybe we'd found a better - less expensive - solution. Thanks anyway. I'll keep digging.
Hey I have a Lexus key but the transponder chip is bad. Can I buy a new transponder chip, use my old key in the new case, and reset my immobilizer to match the new chips code?
the transponder needs to be programmed to the car. The chip is highly unlikely to go bad. Its a passive device that doesn't have any real "moving" parts or power.
@@TunerwithKids this seems like a massive oversight on lexus' part, the fact that the immobilizer can literally shut down your car but can still be reset if a thief has the know-how. i guess they didnt anticipate being able to hack it in 25 years
Will this procedure work for jzs171 ECUs they are 1jzgte vvti very similar to the jzx110
it should be similar for most Toyota ECU of the same era.
There is jzs171 without immobilizers
@@TunerwithKids yea managed to get it to work now have crown vx ecu in my crown
@@4NDR01D5 yes there is but mine has immobilizer and all crown VX's had immobilizers and now my crown had a crown vx ecu. Only 300 of them out there and they made more power from factory, breaking the gentleman's agreement. Higher boost cut and more aggressive ignition table.
Hello, could you please help me with a Lexus Is350 2006 that turns on the immobilizer and I cannot use it, I am already frustrated because I have spent a lot of money on mechanics trying to solve the problem, the last time it only worked for 2 months and now I have the same problem .
Did your ECU have damage? Does it randomly not start? Immobilizer only prevents starting once it’s on it goes until you turn off.
@@TunerwithKids I replaced the ECU but the problem persists, with the new ECU it only worked for two months, the person who inspected my vehicle told me that the problem is not the ECU, it even worked with the old ECU
I have a W55 rebuilt from my 2002 is300 if interested. I am moving to a power glide as I drag race a lot.
Where are you located? I’m tempted to hold out and get an R154.

Can i rewrite ecu vin numbers with the ch341a reprogramar on 2003 toyota celica
Wow I'm surprised you was able to program the chip with it still attached. Mine kept failing and i had to remove it on my Volkswagen
Bing, great information! Is there anyway you can post a video on 2010 Lexus 350. The SUV does not start due to immobilizer on the eco. Thank you!!
Looking at the video about rewriting the immobilizer eprom. I am looking for this kind of info about the RKE for my 2006 Camry. Do you have any guidance ? Thanks
hi everybody! i bought a brand new ECU for my vauxhall astra 1.7cdti with the same part number as old one,but i dont know if the new ECU"s come out from factory with the software already written on it ,or first it need to be downloaded by a garage technician, and after programmed to my car??? for programming its enough if i have the security code of my car? yhx!
Wonder if this would work for JDM tototas.🤔
Should work if they have same immobilizer system. I don’t see them making any different since it’s the same engineering.

Ciao Honda moto sh300 EEPROM 93a66 ho perso le chiavi..posso programmare una nuova vergine oppure annullare immo ?
"Original dump"
outstanding bro can i use this process for my Honda CBR 650 Motorcyle because its also used 93C56 EPROM in its ECU
Anything that uses an EEPROM will work. Just depends on if you know what the code is.
Dear if i send you my .bin EEPROM File of my Bike can you guide me and plz also mentioned you email address or facebook ID thanks in advance
I wouldn’t know what to look at for motorcycle. Each manufacturer is different.
Thanks
Did you have to re-cut that junk yard key?
Naw. Program the FOB and immobilizer to ECU and get a key cut to your existing key or locks.
Thanks Sir
im gettiing ch341 not found on asprogrammer any help?
Üdv; soha ne így csináld mert módosulhatnak az adatok !!!
(Proc.-kvarcot le kell "bénítani" !
Az a biztos 100% ha kiforrasztod !
Can you remove the chip and start the car
Nope. Would need to have someone reprogram ECU to have it removed, if even possible.
Hey, can you tell me if the virginize code works on an 01 IS300 ecu? The chip is the same and I've read the contents. The keys appear to be stored in a slightly different arrangement, but the virginize code matches up if I zero out the other cells. The cells with values that you didn't change to zeros match up, but I had to zero out additonal cells that didn't have values in the 02+ ecu chip. Let me know your thoughts on this.
Zeroing out should put it into learn mode. Make sure the key count byte is set correctly to tell it no keys are programmed.
Is the only thing that prevents another ECU from working in your vehicle is the immobilizer function and whether it will allow keys to work in the ignition?
IOW, after this is done, the new ECU will work perfectly in the vehicle, right? Nothing else is necessary, right? I have an all keys lost situation on a USA Lexus RX300 and I'm going to see if an XTool D7 will program a new key without swapping out the ECU. If it doesn't work, I might be following this path.
No keys means this is only method or pay dealer $2000 to reseed and program a new key.
U think this video wíll work for a 06 Chrysler 300
Idk, they are different systems and brands so doubt it.
Thanks
Mate where is the link for that reader
Check description box for links. I also have some gauge cluster videos that have instructions on how to modify the board to work in cars.
After doing this (and keeping the valet key lockout) it only allowed me to program one key... Why is this? 2002 RX300
Idk, if you reset it as new, the ECU wants to program 4 keys, two master, a card lockout and the valet.
I Lost my master key, how i can make wallet key without any key?
I got lexus mk2 gs300 98
Reset it with this method and reprogram master and a wallet immobilizer card with key cut.
Okay thank you, i got problem to read the epprom. The ic850 is connecting good and i can read, but i can’t connect to the ic900, i Cleared the pins but i still got problem
Well i got connection, what i can see, everywhere i got „0” 😂
Okay i virginized my ecu but its not entering programing mode, light is blinking
Mr. Can help me .can gife file for programmer
My car is 2003 Chrysler Concorde, how do I find out the EEPROM chips? the number?
Idk.
I just lost my last key (06 prius with smart key system) will following these steps allow me to bypass the immo and program a new master key? Thank you, very quality content.
Not sure on the prius, there is a similar chip on that ecu.
Hi Binh, I bought a used Rav4 from an auction with no keys available, do you think if I reset the keys to zeros as you’ve shown, I’ll be able to get the car to recognize a brand new key? Given that I don’t have any key for that car. I appreciate your help.
If its the same era RAV4, late 1990s to early 200s, should be same process.
Can the program run on Mac iOS?
I doubt it. But any Hex editor should be able to view the code. The problem is finding one that has drivers for the USB hardware.
@@TunerwithKids I have a USB adapter 😊
what about the VIN #? does that also get transferred? any videos on how to update VIN # on the cheap without buying expensive scan tool?
No idea, only 05 has the VIN, I believe. I think you may need Toyota Techstream that can flash ECU to rewrite VIN, but not sure.
I’ve gotten to the programming step but I cannot get any key to store. Is there any way that I can troubleshoot further?
Is the key correct chip? They make different variations of the immobilizer keys (H, D, etc)
do you think it’s possible upgrade a regular cut key to a smart push to start key for lexus 430
Not a true smart key, you can add a start button but still need a key.
Très bon vidéo
Hey Binh, great video!
Are you still considering a video about setting up the CH341A programmer? I would greatly appreciate it! :)
Greetings from Germany
Check the video description...I have it on one of my other videos.
Hi dear so interesting can you please give me the link where can I buy this USB programmer
Check the description box.
Sir can ask some questions what software use off immo?
Any idea if I would be able to program an aftermarket key fob? The OEM 2 button key fobbfor my Altezza is discontinued. Tempted to try and link a LEXUS key fob to it.
Should work, the key immobilizer is a “4c” chip used by many cars and brands. The remote portion is different computer and programs differently. Most all Toyota use the same frequency and chips.
Hey all, I was wondering if someone can help me out here. A long while ago, my ONLY key to my 2000 Lexus GS300 broke, and the chip inside went missing. I was able to retain the actual metal key part of it and the car started perfectly fine for a while. Just yesterday (3/31/23) I tried to start the car and it would not start. I began troubleshooting like normal and even went as far as replacing a fuel pump as the engine would crank but not fire up. However, i just noticed that the security light (the little car with the key symbol) is flashing even with the key inserted. I suspect the immobilizer is preventing me from starting the car now. I do have a blank key/transponder but obviously I cannot reprogram it normally without the master transponder. If I were to pull my own ECU out and viginize the immobilizer, would I be able to program the chip in the blank key? Thanks.
If you do this same reprogram it will reset it to new and program any new key. GS3 should have a very similar if not the same ECU as this.
@Binh-Tuner with Kids Thanks for the quick response. Gonna give it a shot since I've not really any other option. Great work on the vid.
Hey Binh were do you recommend to buy a used ECU?
Can you make a video on how to get pincode from immobilizer dump
Pin code? You mean the Techstream ECU flash unlock code?
