My key doesn’t have a chip in, will the PRO Module work?

Absolutely yes. There are 2 main types of factory immobilizers installed on GM cars: Passkey and Passlock. The first one has the chip in the metal part of the key, while the Passlock has the same system but inside the lock cylinder and there is no chip in the key itself. Both systems work in a very similar manner and, if your car is listed on our website, the PRO Module will definitely work on it and bypass the system.
