I just wanted to say THANK YOU! My security light started flashing on my way to work. It went off 10 minutes later. I got to work and tried to move my car to a different parking spot at lunch. Flashing Security light again and no start. I found your video and then measured my key and got my resistance value. I matched it to your list and had my wife bring me some resistors. I tied the resistors in, turned on the key, got a sold security light that then went off. Car then started right up and I drove the car home. The list of 15 resistance values with the calculated tolerance values were much appreciated too. Thank you again!
you can bypass it also by holding the key on for more than one minute if you have a six-speed your foot on the clutch...... after a minute the car will start
You need to install a switch in series with that resistor. The resistor represents a load and will draw a small current and eventually run the battery down. You cannot simply solder in a resistor and leave it at that. So every time you use your car first flip the switch and then start. When you arrive turn off the engine and then flip the switch off. Its that or get a new ignition cylinder installed for about 500 bux unless you can do it yourself.
The quickest way is to make a copy of original key, use copy for ignition and attach lead wire to each resistor lead on original key. Quick wire connect each of those leads to those 2 wires under the dashboard. Tape the key very well and bury under dash. No checking for ohms or connecting a new resister. Don’t let lead wires touch key surface only the metal tabs.
Merci pour cette précieuse info. J’ai eu ce problème avec une Cadillac seville 1997 Je n’avais pas cette info, j’ai dû faire replacer le barillet, très chère !!! Plus dépanneuse.
Thank You for sharing we have a 89 RS camaro we not been able to drive it b because of the vats system it will run some times wen we go out in it it stops running
2 things, I like your connector setup but I'd recheck the resistance value at the plug end of the assembly you made before you install it. Your extra orange connectors will actually introduce more resistance into the circuit (every additional break in a circuit will) so make sure you're still within tolerance. It can save tearing your hair out. Kind of 1A - The most common cause of this is failure of the tiny wires connected to the ignition lock cylinder. It was a dumb design to use such flimsy parts for such a critical system but that's GM in the 90's. 2. I'd have pulled the airbag fuse. Remember that 90's GM's had RAP (retained accessory power) which included the airbags. Even with the battery disconnected the airbag could still potentially be armed. Good video, I had a 96 Camaro and now have a 95 Formula that I'll eventually have to do something like this to. VATS has been screwed up for 10 years on it ( was my mom's car) She got lucky when it failed in the ALLOW state but the Security light has been on steady for years and annoys me.
Car Stuff with El Camino Guy old post , I know, but those are high amp, zero loss connectors, commonly found on brushless RC cars... the resistance is zero, or so low it won't affect it. Besides, you'd be surprised how tolerant electronics can be.
Mike Hagen If it works for you great but don't surprised if something as small as a change in temperature changes all that. The variance in the resistance values isn't that wide and while a connector may be marketed as "no loss" there's no such thing when you break a wire. Only a soldered connection can approximate the original and even that adds a minute amount or resistance itself. Considering I actually have a degree in electronics engineering I can tell you with certainty just how maddening 100 ohms can be in some circuits. But as I said, if it works great. I just don't like to take chances with a circuit that could leave me stranded and that I've seen affected by nothing more than an sensor tap from a car alarm.
Car Stuff with El Camino Guy great points. All worth consideration. Especially for me in Wisconsin, where humidity is constantly changing and has an effect on ohms. I also believe in zero breaks in the wire or soldered, For me , the best (for engine swap) would to have the VATs eliminated from the PCM.. but to get something running right now, the resistor works. .
You know something thank you very much for that chart on the resistance on each level of keys I was in my shop the other night I left my keys to my 02 firebird on top of my desk along with a sandwich and I caught on video a raccoon coming into my shop grabbing my sandwich and my keys and thank God not my firebird and taking off with my keys cuz they like shiny objects, well I knew I just had a key made for it and I remember the number at the dealership it was a number 12 key well now I'm going to go I'm going to go put those resistors in line and put me a push button in for the ignition thanks guys I do appreciate it
You obviously dont need to be anywhere close to any tools or wires that touch any vehicles ever. I would probably never let you sit in my car if thats what you took from that.
I doubt it, unless your bulb is burned out or the system is damaged somehow. If the key isn't working it is designed to trigger the light unless something else is wrong in the system.
Actually series or parallel ain't got nothing to do with it there is no positive or negative to a resistor you just saw their son's b****** together and they're soldered together it's not serious or parallel so I do I do apologize for feeding you false information
I never found an answer technique that lasted. I finally just put a switch at computer ground on car body and tricked the puter into thinking it was another day. Always started then.
@@LegitRaceCraft I bought a bypass module off of ebay before finding these videos about resistors. Any idea how I would wire the module to a 2002 trans am? It has a four-wire interface (power, ground, standard signal and 30Hz signal. Thanks
My 99 Deville will actually start, but it dies after about 3-4 seconds. Message on display says anti-theft error. Car won't restart, but will crank. If I turn off key for a minute, or two, I can repeat the above start and die cycle. Doesn't sound like the key resistor is the issue. Thoughts?
It actually is. When the key is first inserted, it reads the correct resistance. After you push it forward, it loses contact with the sensors and changes so much it thinks it's the wrong key.
Hi there, so I did the the vats bypass with the resistor, but my lights still blink and hear a ding every few seconds. Does anyone have some ideas. My car is a 3.4 L. Thank you
I Did exactly what you did the security light went off but yet it still wont start. What else do you think I could do. Could it be the ignition switch gone out or what else. This is for a 1990 Firebird.
+Sandra Danjanic if there is a bad connection somewhere on the wires then it would. The ignition would have to be worn enough to where the key doesn't touch the vats contacts.
I got a 95 camaro it will start an and shut off the security light is staying on but there's no ignition switch the guy I got it from took it out if I play with taking the battery off and putting it back on it will start and run and move till I turn it off but I can't get it to bypass the vats on it I don't have a key for it and the resistors I got that are 15 of them for GM bypass don't seem to be working with everyone I try
+Logans DIY Garage it most likely wouldn't start. The resistance needs to be correct. I don't remember if there is a light on the dash that flashes or not, but if there is then that would be on
You need to figure out what resistance chip is in your key to bypass the VATS security "feature". With a multi-meter, measure resistance in Ohms. Once you know what resistance you have you can order (So far every key I've checked is available) a resistor on Ebay: approx 4$ free shipping for 10 of them or possibly a radio shack or similar.. Splice one (1) resistor under your ignition (put 9 on your shelf!) onto the wire that measures the resistance. Use some decent connectors and tape! Here's a video for a Corvette: ruclips.net/video/3PkHTxDQpkE/видео.html . I think these resistor-key systems are the same. I've done a '97 LT1 Trans Am with a resistor spliced inline of the VATS wire, and will do an '01 Camaro soon. Does anyone know a way to make a key for the door cylinders without having one? asking for a friend! (Bought from a man whom purchased it from an auction. 1 ignition key, no door keys) If you were to just put a wire in, there would be no resistance, therefore no cranking and no fuel.
I was told if you ground the yellow wire coming from the ecm to the theft module that there is no resistor needed When working right ,passlock From my understanding is that the key sends a signal to the theft module, then the module grounds itself to allow the car to start. Do you believe that this is correct?
I've done this just today on my 95 Cadillac STS, now it won't shut off. Had to pull the ignition fuse to get it to shut down. OH how i LOVE this car LOL!!! HELP!!!
+Dalton Bowman yes, if the key is the problem. If the problem is worn out contacts in the ignition switch then it won't fix the issue. The best way is to change out the ignition and the key, if people don't have the money for that then this is the best option.
If you go to the passenger side door use the key to lock unlock, lock and unlock it resets the security system.

$25 on eBay, get a VATS bypass resistor. Find your code number, buy it, unplug ignition lock wire and replace with this, done.
Good video on help understand my 2000 Camaro thanks man!!
When you put them resistors and end and solder them together that is not a series that's parallel and if I'm wrong I apologize but I don't think so
You know something thank you very much for that chart on the resistance on each level of keys I was in my shop the other night I left my keys to my 02 firebird on top of my desk along with a sandwich and I caught on video a raccoon coming into my shop grabbing my sandwich and my keys and thank God not my firebird and taking off with my keys cuz they like shiny objects, well I knew I just had a key made for it and I remember the number at the dealership it was a number 12 key well now I'm going to go I'm going to go put those resistors in line and put me a push button in for the ignition thanks guys I do appreciate it
You doing very good job 👍👍👍👍
Nice video 👌👌👌👌
You teaching very good you good teacher 👌 👌👌👌👌👌
Thank you!
What settings Do you have your meter on when you testing the resistors
Ohms. 2000 setting.
How could I require this resistor thing if the 2prong plug has been cut off at both ends??
I meant *rewire* the resistors if the plug has been cut off.. autocorrect
You obviously dont need to be anywhere close to any tools or wires that touch any vehicles ever. I would probably never let you sit in my car if thats what you took from that.
Could this be a no start problem without security light?
I doubt it, unless your bulb is burned out or the system is damaged somehow. If the key isn't working it is designed to trigger the light unless something else is wrong in the system.
Pretty good video buddy...

Just did that in 1995 cutlass Supreme it fixed the no start but security light stays on any suggestions
Perfect! I'm not sure why the light is still on, maybe disconnect the battery? But I don't know if that will change anything.
@@LegitRaceCraft ya I tried battery thanks for getting back to me
Mine measured 0.50 so that’s the 502 ohms one
I never found an answer technique that lasted. I finally just put a switch at computer ground on car body and tricked the puter into thinking it was another day. Always started then.
how what did you do ?
I just cleaned my key with alcohol.. Fired right up!!
Awesome!

+Sandra Danjanic I would measure the resistance and then try again. And also check the connections that are on the ignition for the resistor
Ok I will try. Thank you.
Would the ignition switch cause the Vats code to come up.
Also would the ignition switch stop the key from being read.
+Sandra Danjanic if there is a bad connection somewhere on the wires then it would. The ignition would have to be worn enough to where the key doesn't touch the vats contacts.

Did u get it figured out? I do know you have to wait 5 mins or so after trying each resistor. Also try to lock and unlock the door with the key pad
What was the watts of your resistors cuz I only 1/8 watts but 470 ohms
Did you figure it out. There is 1 through 15 different values or 15 different Key's.
Nice ring
great!!!
