What This Part Helps Fix

Installation Notes and Tips

Verify the vehicle’s retaining-screw style and trim color notes before ordering, since fitment varies by application. This ignition lock cylinder uses no harness and does not require key programming. Confirm the existing ignition lock cylinder configuration against the vehicle listing for Chevrolet, GMC, Buick, Oldsmobile, and Pontiac models before installation.

For best results, compare the original cylinder shape, retaining method, and keyway style to the replacement part before disassembly. On vehicles such as Chevrolet Blazer, Corvette, and GMC Jimmy applications, access may vary by steering column design and model year.
