GM VATS Key / Resistor Key Security Bypass
Вставка
- Опубліковано 1 жов 2024
- In this video Eric O. and the crew at SMA show you how to bypass the security system on older GM's that use the resistor pellet chip key also know as the VATS (Vehicle Anti Theft System ) We demonstrate it on the 1994 Chevrolet Corvette but works the same all the way across the board on older GM VATS systems.

I think it wants to be put out of its misery.
I liked it. 👍
It sounds like it's dying
No, it's not. Try a 1985 Toyota Tercel.
that system has prevented more legal owners from starting their then ever prevented thefts. Radio Shack $3 fix

Resister part # please.
There is no "part number". Simply measure the resistance with an
ohm meter, then go to an electronics store and buy a resistor with
a close value. You may have to buy two resistors to get the proper
resistance, in SERIES.
I actually fixed it properly, REPLACED THE BCM, done.
The clutch pedal prevents most car thefts these days anyway.
The only person I even know who can't drive a manual is an in-law... and he has no driver license.
👍😂😂😂🤞
Ha! Ain't that the truth! That's a keen observation.
ykmalachi millennial anti-theft device.
What's a clutch?
did i miss the brake cleaner and reach around segment? lol
Hey Eric... Good vid AGAIN! Hanna is gorgeous your'e lucky in SMA we just have Dave!
I love the fact that you are a mentoring Hanna. She is learning from the best person. Good for you Hanna!!!!!!!!!
Hannah is famous.
Your air hammer is infamous!
Nice video SMA.
I almost bought a $200 starter when all I needed was a $3 resistor set. 😂
UA-cam is a godsend
I really don't understand why this channel doesn't have over a million subs.
I imagine because it does not appeal to the mainstream audience. To specific of a group and liking. I think you need the BS videos like "how to wash your windows" and "how to paint you rims" type of videos to have a big following. It is OK, I like this group we have :)
Are you mad bro.?
john CR i'm not mad no
Hahah, yea The more stupid the video is, in the same format as everyone else the more appeal is gets. It makes some sense, I guess one has to figure that is the way the world is going, Mindless! Hey On those Pass Key resistor key's, if you have anyone in area who re-flashes the PCM, You can delete that pesky bugger that way too. I should "uncheck it" next time I reprogram the PCM in my car. The 94-5 F body Y body or B body has to be the easiest/ cheapest vehicle to get DIY re flashing equipment for. Not worth it you don't own one of course. With a cheap ALDL cable, anything parameter can be changed for 30 or less with freeware.
Eric, I'm gonna be very surprised if your channel doesn't easily go to the top of professional mechanics. Your skill level is unsurpassed as is your video editing skills. Other mechanics are viewing and enjoying your videos, as are the DIYers out there like me, that while I can't do all the jobs you do of course, I can enjoy following along as you make things enjoyable to watch. A telltale may be if you go a few days without uploading a video, people are starting to get edgy. Highest marks for your channel !
BRO seriously the only video I’ve seen with an actual hack that you don’t need a master key thank you for actually solving the problem and saving me a bunch of money you’re awesome lol
"Go pedal" and "whoa pedal?" I will find a way to inject that into a conversation soon. :)
I must have missed something when i got to the "sat" pedal. easily mistaken for the Q pedal. q the next gear, q neutral. sat pedal I'm talking about.
You should be wearing a gold chain necklace while working on this car
I gave you a thumb up even though the image made me shudder.
Gm should have done a recall
Looked like he took the car audio display inside best buy and installed it in there
It's a c4, nothing you can do to it will make it worse.
hahaha I was thinking the same thing
More like Walmart.
Radio Shack .... they should put an 8 track cassette
Dr. O -- I always like to watch your videos as they are so educational and informative. However there is another fix that is somewhat faster and less involved and more permanent than adding the resistors in a bypass circuit.
Whenever the ignition switch is in the RUN or START position, 12 volt power is fed through the clutch interlock switch or PRNDL automatic transmission neutral start switch. If the clutch pedal is depressed or the automatic transmission is in neutral / park, 12 volt power continues to the control side of the theft deterrent relay. It passes through the relay control coil and onto the central timer module on a yellow / blue wire.
If the central timer module receives the correct resistance from the ignition key it grounds this circuit which completes the starting circuit at the theft deterrent relay from the ignition switch to the starter solenoid. You could just permanently ground the yellow/blue wire at the central timer module and avoid having to match resistors and solder. The safety features of the clutch interlock or PRNDL safety switch would still be enabled. Just another option.
The only place I've ever heard this fix! Hope a central timer module is easy access!
Hey Bud I was wondering if you know why the key would stay stuck to the postion before start and not turn back? It started to make this funny starting sound like the starter was about to go up. I tryed to start it 1 more time it cranked alittle and didn't start. I added the jump box because it sounded very weak. When I tryed to start the key stuck
Security light was coming on than going off at first. Now it doesn't show at all
Will only crank like 2 times that seems like a dead battery even when hooked to a jump box. Why is there no Security light and key won't turn all the way back? Thank you
can you bring that box of resistors to the valet parking lot at the Hyatt? I need to get you to bypass about 12 cars I left there. Thanks
Randy T Lmao!
yep,,,had to do that to my 91` Vett.. but secirity light was not flashing ..so for a hack like me It took a bit to diagnose.. in other words I removed the starter.. bench tested it ...and was pissed ..LOL ..17% on ebay for a pre made plug in resister btpass
Pro Tip... if you cut the wire on the key cylinder side instead of the factory side then you can make your connections outside of the car and just clip it in the car. Also you won’t have to worry about losing the the factory side connector if you ever do replace the key cylinder
Nailed it!
Just a thought... Rather than cut wires on the harness side, I would cut on the ignition switch side. The wires to the ignition lock side are part of the switch. That way is someone replaced the lock it would be good to go with no cut to the wires.
Found a lot of these VATS fixes on UA-cam, this is the only one I've found that shows what and how to do the change.
Best auto repair channel...period! Eric you do an amazing job👍👍👏👏👏
Thanks!
Tell me will it work on a 92 allante while it's in theft disengaged mode. I came out of a store went to start it and it wouldn't start and said theft deterant disabled wait 7 minutes I have tried repeatedly and checked everything outside under the hood parking gear also have another key neither of them would start the car horn and all works but when I disengage it car still will not start
Good vid.
I have done the same myself=I also have installed a new lock cyl., with proper VATS key, under the floor mat to save the customer of the steering column labor $$$.
The only problem is if the column is started with a screwdriver, who is to fault?? Not GM, could be the Tech, unless the info is in writing??
Thanks again..
LOST in TIME !
Solder the wires to the resistor in the key itself (spare key) and tuck the whole thing up under the dash. Works great and you don't have to go find a resistor.
Just for curiosity reasons, why do you use the exact reading from the key vs the corresponding value in the VATS spec? There are 15 of them, this one should be a 1.8k I believe. Not there is anything wrong with your method of playing in the tolerance as long as it starts that is all that matters. If you are unable to locate the value from the key for any reason, like it is damaged, you can make a plugable selector to insert where you pulled the connector and rotate values until one of the 15 works.
VATS = Vaultech Automated Targeting System.
Took a while to figure out why the video title sounded so familiar.
I clicked this video just to see how far down I would have to go to find this comment.
Vehicle anti theft system
She's cute. Asf and a mechanic lol
She married a (VERY) wealthy boat mechanic who owns a "giga yacht" and now lives in the south of France. Has two children, Eric and Erica (twins), who drive Porches and Ferraris. She doesn't mind being a trophy wife and all the perks that come with it....gold and platinum jewelry, gowns by Halston and servants.
She sends Eric and Mrs. O a Christmas card with a check for $10,000 every year. Yes, she is happy!
Nice video.FWIW, when I do these, I cut the lock cylinder side of the connection rather than the other. If it ever needs to be repaired correctly, the new lock cylinder comes with the length of wire and male connector anyway. Therefore, as far as wiring goes, future repair is simply unplugging/removal of resistor assembly and plugging in new lock cylinder. Added bonus - this way also allows you to build your resistor assembly on the bench rather than working under the dashboard!
Andrew White honestly, with as kinky as those security systems were, it is better off being bypassed
Exactly!!
@@TheCrystalGlow he didnt say not to bypass, he said to bypass on the other side of the connector as to not cut into the vehicle harness
I do it the same way
Very, very nice! Do your method involves taking the lock cylinder out of the car to wire in the resistor?
So I told you last weekend I was putting in a VATS bypass on my 1990 vette. I dropped the to panels and some yahoo over the years done a little splice and dicing! Now I’m back here see what I can find out without having to drop the steering column. Yes, I’m a lady, 59 to boot! Not giving up. Just double checking
Did this to my old LeSabre 2 years ago....still working fine.
Had to do this to my 91 T/A. Miss that car. Oh and more Hannah less you. 😜
97' and newer years with VATS, they can be turned off in the PCM by a tune :) *did it on a 98' TA
She fine and the girl pretty too
smartest guy on youtube. best mechanic Ive seen period. honest as the day is long.
Hannah should contact us... say something ;-)
...
BTW she is pretty.... Thumbs UP! Give her some confident...
That's next.
Ducky1521 you mad bro?
I LOVE YOU MAN! YOU KNOW YOUR SHIT I'VE LEARNED SO MUCH FROM YOU😂😉. HOW TO TROUBLE SHOOT & FIX THEM.KEEP THE VIDEOS COMING!!!! DETROIT'S MOTOR CITY STEVE
Hi Eric
How do you find these wire diagrams?
This is of course mandatory for a remote start system... Made a remote start/alarm/door lock/window control install diagram if anyone's interested. It's a viper on a 93 convertible, but good info for other years/models...
Fun fact: In 93, Corvette was the first car with optional automatic door lock/unlock, via a antenna loop in the drivers door which sensed the wireless remote. Though you did still have to take the key out of your pocket and do the manual thing to start it...
Thank God they evolved into something that you could use
GREAT WORK ERIC . EXACTLY HOW I WOULD HAVE FIXED THAT VATS ISSUE.
I guess 2 people that disliked this video work for gm!
They were most likely the engineers who designed the VAT system in the first place!
Lol
They may be the same engineers who designed the placement of the Cavalier oil filter!
My saying is in my garage "Dragged In, drove out"
how about" pulled in pulled out"!
can you tell me how to bypass 2008 aveo theft control module crank no start
Eric, great video. My wife has a 93 C4, and had a very similar issue with it not starting. Back at the time, we took it to a guy locally that is a Vette specialist, and he had the vehicle running in a matter of an hour. It sat at a Chevy dealership back then (2008/2009), because they said it was the BCM, and they were trying to locate one. I heard of this Vette guy from someone at work, and we had it towed to his shop. I just have one question: With the VATS module essentially "always seeing a key in the ignition with this bypass", I wonder if it affects the vehicle's security system from locking the car and I'm assuming as most GM vehicles do, disabling the vehicle from starting. The wife's remote hasn't worked in her car for years, and we just manually lock/unlock the doors. Anyway, just curious about it as it came to my mind as I was watching the video. Great video from you as always!! I enjoy following your channel!!
hey thanks for the info my 1995 Aurora ignition took a dump today and thanks to your video I'm doing away with this retarded Pass Key bull. thanks
Thanks Eric and Hannah...I've got a 93 C4...So far l haven't had this problem but l'm sure it's going to happen...
I had this done to my 94 Caprice years ago bit now my car will not start and the shop said i need a security module is there any other way to fix this? I don't want the same issue years later
Nice cheap repair & another happy SMA customer who saved themselves a lot of money by bringing ti to you.
Maybe in the city. In texas you're an outcast if you dont have a basic understanding on how to drive stick
I put 2.2 kmh on a 2003 chevy express and didnt not work Idk if you need to do relearn 😮
Eric O. Let's put an end to this question. Is Hanna your daughter?
I thought she was a random apprentice, poor kid looks lost on camera though
Hannah is not Eric's daughter. he mentioned in the comments of another video that she's the shop assistant who's in the shop when not in school.
James Last yeah I was silly enough to call her his wife, I thought Mrs O had a hair colour change 😳how embarrassing! This is my first comment since on Eric o's channel.
Cool that she takes a interest in helping. She'll shock the hell outta future boyfriends.
Another awesome video but a couple years too late...Buick rip. 😏😕
Excellent video! I had to do the exact same procedure in my 96 Impala SS. One day after work the Impala wouldn't crank. I went back in the shop and fabricated a resistor combo that closely matched my ignition key. Spliced the resistors in where the connector is under the steering column and BINGO! I did that maybe 10 years ago and the Impala still starts without any issues.
Does this work on a 2001 chevy monte carlos ss 3.8l
@@troysmith3054 Can't say for sure, but I'm assuming it would.
I can't get it to work
Did you try using the other key? (they all have two)
Good video, I knew they were resistors, never knew you could modify in that way, Hannah has a nice smile as well.
Hannah is beautiful.
And that door chime is the worst in the world! Lol
she really takes on her dad's features
She looks like Eric with long hair
ChillCosmos Hannah is not Eric's daughter
matpsim why she look so much like him
I love that door chime!
Will this work on a 2001 z28 Camaro my friend?
Whoa, that audio system is the bomb! Its like those radios you could take out and with you back the day. The owner can pull up to the beach and bring his tunes with him!
(Boom Box) Must also carry 12v battery.
That sounds !ike a country song..."came in on a tow truck going home on its own.
The '91 Reatta has VATS and many have had to do this bypass. Thankfully- my '89 doesn't. All 4 years have RKE, and '88-'90 VATS consists of a lockout module, that kills power to the fuel pump and ignition if the locked doors are opened without the RKE or door key, triggering the alarm (lights flash, horn sounds). This was a very common failure, mostly the column wiring at the tilt point. Here is some more information on this- and a Tutorial, put together by Reatta owners and Members of the AACA Reatta Division- Your video is a very nice addition to this, a video always helps! Nice to see Ms. Hana, not so camera shy! That's how I got my start in automotive repair, being an Apprentice from age 10 to 16, then working like Josh until I was 27. Now- I just enjoy retirement and DIY. Eric- you and a few others on UA-cam are very charitable, taking time to make videos, thoroughly explain stuff, a give sound advice; you are much appreciated, thank you. Here is the link to more VATS info- reattaowner.com/roj/component/content/article/62-electrical-system/other-electrical/232-vats-passkey-system-bypass-instructions
just had to do this on a chevy 2500 6.5 except what messed with us was it would only crank, it would bring fuel up to the injection pump but not let it go passed to the injectors. Security light wasnt on it messed with us so much because it started up and ran but had bad heads which is what we did along with a turbo intake manifolds and really everything. trouble shot everything, all the solenoids, switches, even lead us to believe it was the pump itself, pulled the dash, burned out bulb put a bulb there security light came up, just ripped a resistor off of a spare circuit board we had laying around tied it in and it started right up
I'm so excited that this may work for my 1994 Oldsmobile Cutlass
WOW Beautiful girl!. But anyways back to earth lmao I just watched other videos of this trick and yours is 100% better and explain more on how to do it. Thanks!!! I have a 94 Z28 and I think it's been bypassed BUT my security light is still on, maybe I need to redue it from what the last owner did????
Always a better time with Hannah or Mrs O making an appearance
Awesome video as always, sorry if this is mentioned already in comments, but do ya happen to remember the brand on those wire strippers/crimpers you were using? I really like that design with the crimper in the beak rather than the handle half of the tool!

Ducky1521 why you hating? I see no Ill comment made at all.
Yeah he’s just a piece of crap that likes shitting on someone else, makes him feel better!
I Assume you got the OK with customer for the modification there..
I wish it was this simple with SMART locking from Ford..
Eric, has the best video instructions and explanations, for this fix, of the security system.
Thank you for this video! It is a big help!!
"Came in on a tow truck, going home on its own"
Hey man, I have an 01 C5 Z06 and it's doing the same thing. Is it the same wire location for the C5s do you know off hand?
there is a similar wireset on the c5, exact same setup under a new name and combined into the BCM rather than a separate module.. steering column lock is a known issue with the c5's too..
Thanks to this video, i was able to bypass the VATS in my 91' Camaro, thank you so much!
I also have a 91 Camaro I am getting spark and fuel pump is coming on security light does come on I noticed the injectors are not opening bc it will start off of starting fluid
Great fix
Gotta have your daily dose of Eric O humor. Makes everything right in the world.
Lol thanks
At the dealership that I work for we had a tool called the interrogator you unplug the column plugged i KNMNM in oh when you just dial to that number and then you were able to diagnose the
@@johncomito4718 753³
How do you find out what size of resistor go in it if the resistor when the key drop out
Turn those speakers around and gain at least 15 pounds of thrust
Hay show appreciate that fix..got a 1996 caddy deville it cost me $160 the last time so i think ill try that
Nice permanent fix, happy customer and Hannah looks fab !
I'm sure he could of backprobed the connector with the home made resistor without cutting it.
Wouldn't have worked all the time. He mentioned that it was intermittent. So when it acts up, the resistor would take over. When it didn't act up? The system would read the key resistor + the resistor. So the security system would still trigger and cause it not to start.
Hanna sure is cute.
Tedybear315 the connection reading the key resistance is disconnected per the video, it will always ONLY read the resistors he put in
Nice and easy. All repairs should be this easy. Great job Eric. -John
Buy a two stroke motor like those on the chainsaw or lawnmower to power your bicycle. You will find everything is so easy to repair.
That car makes pitiful sounds
Hmm. I don't know, this video camera so late in the day not sure if I can watch it... oh wait there's Hannah. I'm in 😇
Nice! I wish I knew about this a while ago. I had a 2000 Pontiac Firebird with this system. A shop charged me $300 to fix this.
At least you had the money to throw around. A good sign of a healthy and functional life.
One thing for next time, I would suggest cutting the connector on the key side, then you can connect the resistors at the bench. That way all you have to do is go under the dash and plug it in. One other thing I have done is put a label on the wire with the resistor values for future reference, just in case they go bad. Hope I made sense, once again, great video as always and I appreciate the time and effort you put into making the videos.
Ricardo M. Great input..thanks
I doubt that the replacement resistor will ever go bad. The reasons that these
VAT systems fail is in the wiring that goes down the steering column or in the
ignition cylinder, not the resistor. There is very little voltage or amps in that
circuit, hence the thin but fragile wiring. You can always measure the resistance
in your original ignition key if you need it. Or you can write down the resistance
value of the chip in the ignition key in your owner's manual, so you can easily
find it if you need it.
The resistors won't lose their color bands. All somebody needs to do to figure the resistance is to calculate the codes on them.
I love your channel saved me a lot of money and time as for them other channels I call them clown videos I prefer ones like yours 100%
I'd stay broke all the time if I live there, cause I'd cause something not to work so I could bring it in to be fix just so I could talk to Hanna
Hannah is a beauty and she has a great teacher. Thumbs up.
HAHA! how far is the nearest IHOP from Avoca NY?!? Good info Eric for us Chivy guys.

Why....you in love with her also?
I always liked 'Home of the Full Gorilla" for a motto. Then you could put a little graphic on the screen when tightening things for the different gorilla strengths to use like 1/2 Gorilla, 1/4 Gorilla, 1/8th Gorilla, Baby Gorilla and Full Gorilla. That would be hilarious! Should be on T-shirts and coffee mugs..."South Main Auto - Home of the Full Gorilla".
I always leave your channel having learnt something!!
Cheers mate!!
This video was just what I needed, when I needed it! Fixed my 95 Camaro Z28! No tow necessary!!
That is a super annoying chime.
I remember whenI had a 96 Pontiac G6. When I was a soldier in the barracks in the parking lot a 99 model another soldier had accidentally lock his keys in his trunk when taking stuff out. I saw this happen in the parking lot and since I had an older model of the same car and tried my key fob on his car and it worked! That surprised both of us but at least he was able to get his keys locked in the trunk.
Terry Rodbourn 96 g6 I think not
I believe it happened. I used to be a tech at a chevy dealer. While I was there I bought a new Chevy 1500, 1998. I had some work done in the pro shop due to being a conversion pkg and under warranty. Somehow my keys and the pro shop's managers keys got mixed up. Our key fobs worked on eachothers trucks but the keys wouldn't start the others. His keys would turn the dash lights on but wouldn't allow it to run.
I did the best GM bypass ever,,,, i saw one parked at the side of the road, i walked two blocks in the wrong direction, just to make sure my fix was secure :) ,,, didn't work for long ,, those faults are everywhere :(
I bought a similar resistor kit online just so I could get the power locks to function on a remote start I installed in a Jeep Liberty. Jeep requires very different specific resistance for the lock and unlock trigger outputs. Those resistor kits are great to keep around! Always finding uses for them! Great video Eric! Had to be a challenge to video it under a corvette dash!
awsome video man. I liked and subscribe. I wanna learn more on security systems and taking things apart too. also I have Q. I have a 01 Pontiac Montana minivan and the security system wont allow me to start the van. does this method work for it or no.
That Wall of Sound is a real throwback. In-dash CD player included.
Wall of Sound, your killing me.
I REALLY LIKE YOUR VIDEOS I HAD BEEN LEARNING ALOT !! THANK YOU SO MUCH FOR YOUR TIME
Those resistors are handy for "fixing" knock sensors, airbag lights, seat belt pretensioners and more!
ishootstuff yes cause the safe and responsible thing to do is bypass airbag and seat belt warning lights ... smh
Sometimes on older vehicles when you cannot get the parts anymore due to be obsolete you do what you got to do. Also back in the day people drove without seatbelts and airbags.
Someguy6571 they also died a lot easier as a result of the lack of said devices.
People die today due to said devices as well. Nothing’s full proof. Still I agree it’s much better today than back then. A LOT safer.
Seat belt warning lights don't MATTER, as long as you wear
your seat belts, which is still the best protection you can give
yourself. As for the airbag warning lights, I had one once, the
problem was a corroded sensor behind the front bumper. If you
get such a warning light, that is the FIRST part that you should
replace.
hannah is in the shop!!!!!!!!!!!!!!!!
Nice job, Eric. I wish i had a helper as good as yours.
That is the ugliest chime I've ever heard!
