Ignition Lock Cylinder

WARNING: This page does not describe the selected car, but rather 7 other vehicles, including the 2002 GMC Yukon XL, 2002 GMC Yukon, 2002 Chevrolet Tahoe, 2002 Chevrolet Suburban, and 2002 Chevrolet Avalanche. However, it is still accessible from the selected car via links, so may be relevant.

The ignition lock cylinder performs all of the functions of a lock cylinder on a non PK3+ equipped vehicle. The ignition lock cylinder for vehicles with PK3+ may be located on the steering column or on the instrument panel. In either location the exciter coils surround the ignition lock cylinder such that they are very close to the head of the key which contains the transponder pellet.

If an ignition lock cylinder is replaced, the PK3+ keys must match the mechanical coding of the new lock cylinder. When replacing an ignition lock cylinder, and new PK3+ keys are required, refer to Programming Theft Deterrent System Components .
