Did the originals have a chip in them? If so did dealer program it to work? I have a key with no chip to just open my car but it is not programmed to start my car. I need to use a programmed key to start it. Ask dealer if u don't know. Typically a programmed key will be $80. or more

Exactly! Any new keys must be programmed to the vehicle for them to start the engine. If you have a working key try this. Start the engine with the working key. Shut off the engine and remove the working key. Immediately insert the new key and turn the ignition to the run position but don't try to start the engine. Watch the security light on the dash. Within a few seconds it should go out. When it does shut off the ignition but don't remove the key. Now immediately start the engine. If this works your new key is programmed. If not, the dealer will have to program it for you. Don't waste your time on the 10 minute and 30 minute reset that everyone talks about and thinks will work for any GM security system problem. It doesn't!! That procedure is to be used as part of a very specific repair to the security system. Hope that helps! Jim
