Hi all!

ok, so I lost the only set of keys I had for my ‘91 Firebird, have no idea of the VATS resistance but still need to get a new set, how do I find out what resistance I need without the keys and how can I get new VATS keys over here? (U.K.)

 

Having tried to figure that out, minus the VATS issue (mine is bypassed), its a pure pain in the ***, even in the USA.

Honestly, if you can get into the car, I'd just buy a whole new set of locks, and bypass the VATS.

 

Get a set of VATS resistors and try each one, one at a time, until you find the one that allows the car to start. After each unsuccessful attempt, there's a waiting period before the proper vats value will work, so it takes time.

 

The problem is less about VATS and more about what key code the locks have. It’s not possible to look up key codes by VIN anymore.

and even if you do have the factory codes if the locks were changed they will now be different.

 

Vats lock sets aren't expensive or hard to find. Neither are uncut blanks. If a person were motivated they could work it out easily enough.
