Just bought a 1997 seville.
Been inside garage for most of its life.
The guy i bought it from said his dad that bought the car new had lost the fob.
And then he told me the dealer or someone said it was going to cost too much to repair because it needed something else.
I think it was the body control module.
I notice you have to open the trunk because the gas cap door electronically does not work

 

Where is the best place to buy a key fob

 

i would check the bcm first
no sense spending money if u cant program the key fob

 

OK
But i do not even have a key fob yet.
I ordered two factory service manuals off ebay yesterday

 

Ordered a BEC off EBAY just in case i need it and for a spair.
