Key Identification and Usage
WARNING: This page is about a different car, the 2004 Cadillac CTS. However, it is still accessible from the selected car via links, so may be relevant.
The keys are double sided and reversible. Each key contains a key transponder that interacts with the theft deterrent system on the vehicle when the keys are inserted into the ignition lock cylinder. The keys have 10 key cut positions (1) with 4 different cut depths (2) and can be identified by a PK3+ stamped on the key blade.
The keys that are furnished with the vehicle are two Cadillac master keys that will operate all of the lock cylinders on the vehicle.
