What does the TL-163 lock cylinder do?
It is the keyed lock cylinder for the tailgate or trunk. Turning the key rotates the cylinder to lock and unlock the closure. It replaces a worn, jammed, or damaged original cylinder.
Will this fit my vehicle?
It is a direct-fit replacement for GM applications such as the 1982-1983 Buick Regal, 1991-1994 Chevrolet Blazer, 1983-1994 GMC Jimmy, and 1991-1994 Oldsmobile Bravada. Check the Buyer's Guide tab for the full list.
Why is it listed as both a Tailgate Lock Cylinder and a Trunk Lock?

What are signs my lock cylinder may need replacing?
Common signs include a key that won't insert or turn, a cylinder that spins without operating the latch, or a closure that won't lock or unlock. Diagnose the cause before replacing.
Does this come with keys?
