Ignition Lock Coding Instructions

These 2 instructional pages give you step-by-step instructions for building a lock to fit an existing GM key for vehicles beginning in 1995. These instructions are applicable for both in-dash and in-column lock cylinder designs. It is often necessary to recreate the original lock in order to maintain convenience or to accomodate a Pass-Key system. These instructions will show you how to read a key, install the wafers (tumblers) and check your lock for accuracy.
