Your Caprice has GMs VATS (Vehicle Anti Theft System). You have a "chip" on the shank of the ignition key, correct? This "chip" is actually a resistance block that when inserted in the ignition lock contacts 2 tiny wires to tell the computer the correct key is being used. These tiny wires wear and break so they don't touch the "chip" anymore when the key is inserted. Replace the ignition lock cylinder. That's the most common cause for this problem. The new lock cylinder will have a template for cutting new ignition keys. BUT you MUST get the correct VATS key blank for it to work. There's 15 possibilities. You'll have to take your old key to either a good locksmith or your local Chevy dealer. They have a machine that will tell you which number VATS blank (1 thru 15) you need. HTH. -Jim

Are you sure that you have the correct VATS ignition key? There are 15 possibilities. The new lock cylinder came with a template for making the new ignition keys. But you must have the correct VATS number key for it to work. Otherwise the car will "think" you're trying to steal it with the wrong key and refuse to start. HTH. -Jim
