To replace an ignition lock cylinder, does the steering wheel have to come off?
Yes, and there's more. You have the VATS (Vehicle Anti-Theft System) security system. This means that you need to know which key you have. There were 15 possibilities. You're local GM dealer or possibly a good locksmith can check the chip on the key and give you the right number key. The template provided with the lock cylinder is for cutting the new keys only. Unless you have the correct number key blank to cut (1 thru 15) it won't start the car! HTH. -Jim
