Good afternoon,

First, there is no way to disable the theft system without a compatible scan tool. Second, do you have a spare key you could try? It sounds like your key has lost programming.

tried spare key.....vehicle will star at times, then at other times engine want respond,
GM Mechanic: Jared D, ASE Certified Technician replied 7 months ago

In that case the passlock sensor likely needs to be replaced. This will require programming after it is changed out. Your best bet is to have the system diagnosed by a qualified automotive locksmith. They should have a scan tool that will be able to test the transmitter and the keys to see which is or isn't communicating.

Have you ever had the vehicle scanned for trouble codes?
