Master Key Systems
A1 makes it easy for you to have structure when designing an organized key system that involves multiple layers of supervision. Master keying involves making at least two different keys work in one lock. This would help when one person needs access to all doors and any other individual only has access to one door.
We can create and file a master key system to fit your needs.
If you want real key control, check out our high security locks. High security locks allow for key control and proprietary key ways with higher grade locks and cylinders.
