Automotive Keys GM B107 / PT04 (PK3 Z) (691205) Vancouver

The PK3 in the name refers to GM's Passkey 3 system, which replaced the resistor-pellet keys of the 1990s with a transponder in the head. This key pairs the B107 blade with that chip, and the 691205 is the Strattec number, with PT04 being another catalogue reference. If your GM key is a plain black head with no buttons and the vehicle dates from the PK3 era, this may be your key; ask us to confirm, as B107 was also made in non-chip versions. Cutting gets the blade to turn the ignition, and programming gets the Passkey 3 system to accept the chip. GM's procedure for adding a key on these vehicles can involve the car sitting through a timed relearn with the key in the ignition, so do not be surprised if part of the visit is waiting. We do it with the vehicle present, after seeing the registration and your photo ID. Having a working key speeds things up, and when there are no keys at all, we originate one at the vehicle. These keys are often found on trucks and SUVs that are still working hard, so a backup key is worth having before the original wears out.
