Ignition Switch Door Lock Cylinders With Keys For Chevy GMC C K Suburban

Product Overview

The ignition switch and door lock cylinder set provides a single-key solution for tired, worn, or damaged lock systems on classic Chevy and GMC C/K pickups and Chevrolet Suburbans. It replaces both the ignition switch and the door lock cylinders so all locks operate from the same key, restoring security and convenience. This kit is ideal for automotive locksmiths, restorers, and truck owners dealing with stuck tumblers, lost keys, or inconsistent door locking.

• Includes ignition lock cylinder, ignition switch, door lock cylinders, and two keys
• Steel and zinc-alloy construction with chrome-faced cylinder plugs for durability and corrosion resistance
• Pre-assembled tumblers matched to the supplied key code — no hand-pinning required

Common Uses

• Replacing a seized or worn-out ignition switch that causes no-crank or intermittent start

Frequently Asked Questions

Q: Will this set work if my truck has a tilt steering column? A: Yes, the ignition switch assembly is designed to fit both tilt and non-tilt steering columns on C/K and Suburban models; always compare the lock cylinder shape before installation.

Q: Are the door lock cylinders weather-sealed? A: The cylinder faces include a dust shutter and the internals are lightly lubricated; applying a thin coat of white lithium grease on the tumblers after installation helps prolong service life in harsh climates.

Product appearance and specifications may vary slightly by batch. Compatibility may vary by serial number. Verify fitment before purchase.
