General Motors (GM) locks are designed with security and versatility in mind, typically incorporating 4 primary and 4 secondary keyways. This configuration allows for a more controlled keying system that can accommodate a variety of applications while maintaining a level of security against unauthorized duplication. The combination of these primary and secondary keyways provides locksmiths with the ability to create multiple keying arrangements, ensuring that different keys can operate specific locks while keeping unauthorized access to a minimum.

This design helps facilitate the management of keys for vehicle security systems, allowing for less complexity in the keying process while still offering protection against locksmith manipulation. Knowing the typical keyway configurations is essential for locksmiths as it directly affects the key duplication processes and the types of tools needed for servicing various GM locks effectively.
