I bought a 1990 camaro that was a repo. Have a major problem, no key. I changed the ignition, and still cant get it going. Can some one explain to me how resistors work? And instructions on what to do.
Thanks

thats interesting. i dont even need my key to start my car.

 

You probably either dont have VATS, or have it bypassed. And it sounds like you need to replace your ignition lock cylinder.

 

Because yours is an 87.

VATS started in 89, but it was possible to have a GTA with VATS in 88.

 

I believe the series of resistors you need totals 875kilo ohm, the unit of measurement for resistance is an ohm. my ignition grenaded and i wired resistors from the electronic shop together (in series)then wired them soldered this configuration between the wires that are in the ignition on the steering column. (When you take apart the ignition it will be obvious))The original key has a resistor in it that would allow the car to start, by using what i say it should fool the computer and you only need a regular key to start the car. If I find my old broken key i will measure the resistance and post so hopefully i am right. The resistors might cost ya 10 bucks.

 

There's like 12 different "ohm readings" for VATS, not just one, though.

 

15 to be exact.

 

Eh, I was close.

 

Might want to call a locksmith and let them figure it out. My locksmith charges me 40.00 for a reg key. 100.00 for a chip key. but then again i get a discount cuz i own a towing business. u might want to show the locksmith the original ignition and see if he can help you. GOOD LUCK!!

 

This explains that VATS started in 1988 on the GTA; the majority of the 1988 GTAs received the VATS system (6,440 of 9,765 US)
