From the factory, the standard cab trucks had a keyed lock on the drivers side door. The Custom Cab trucks also had a keyed lock on the passenger side door, as well as, a keyed glove box lock. Originally, one key fit all four locks. Aftermarket kits are available, including drivers door, passenger door, glove box and ignition. They are under $100.00 and are well worth the investment, not to mention the added security and novelty.

I believe Classic Parts, formerly Chevy Duty, as well as, LMC Truck and many other aftermarket truck parts suppliers sell these kits. Good luck with your project.
