Restore the security, convenience, and factory appearance of your 1973-78 Square Body Chevy & GMC Truck Outside Door Locks & Ignition Cylinder Set with keys. This complete kit replaces your worn or damaged lock cylinders with factory style components that are keyed alike, allowing you to unlock both doors and start your truck using the same key just like it did from the factory.
After decades of use, original lock cylinders often become worn, causing keys to stick, bind, or fail to turn properly. Many classic trucks have also had individual locks replaced over the years, leaving owners with separate keys for the doors and ignition. This complete replacement kit eliminates that inconvenience by providing one matching key set for all lock cylinders.
Manufactured to closely match the original GM design, these lock cylinders feature the correct appearance and fit for an authentic restoration. The kit includes GM logo keys, factory style retaining hardware, clips, and new outside door lock gaskets for a clean, professional installation.
