yes, need it to start the car.
No, it does not
No.
No.
Yes, they do. They use the pass key chip system.
this is caused by ignition lock cylinder failure, you will have to replace the ignition lock cylinder and key.
not too sure, but if it's like the others, it's wired into the ignition cylinder. Does your key have the little resistor chip in it? (you can't miss it) If so,then there ya go.
That kind of key was not used in 1995 models.
No. You have to get a key cut with the correct value resistor in it. The new lock cylinder comes with a key with no chip.
Using a VATS interrogator. A locksmith is a expert in this field.
If your key has the anti-theft chip on it, the best (and likely only) place would be a Chevrolet dealer.
I called on my 1995 Camaro and the dealer said "between $10 and $100"
On a 1995 Ford Explorer : No ( at least my 1995 Ford Explorer XLT doesn't )
