ignition key

I have a 1996 Olds Cutlass Supreme. sometimes the car won't start because of the chip on the key. If I rub the chip sometimes the car will start. The car has always eventually started, but sometimes I wonder if it will. Should I buy a new key, or how else can I resolve this problem.

Re: ignition key

Sounds like the only way to go is replace the key. Go to a Buick or Chevy dealership parts department. If the problem is something other than the key itself, they may be able to help you out at a minimal charge.

Re: ignition key

VATS (vehicle antitheft system) is the older system. The newer system is called Pass key 2.

The system uses a chip in the key so the security system can recognize the correct authorized key. If you don't have a key with the correct chip then the car won't start.

If you don't have a key at all, then you don't have any choice but to buy a new cylinder with matching keys.

You will have to go to a GM dealer or professional locksmith for them to match the key code with the security module. They have a special tool that can match the proper chip but it takes time. Every time they try a key code and it is wrong the system goes into a lock down mode for four minutes, then they can try again.  I think there are 15 different codes that are used.

Once they find the code then they can install the correct cylinder with matching keys.

If you need more information we will be glad to help.
