Master Key System Done Right the First Time

A master key system lets a property manager, owner or maintenance staff open every door with one key while each tenant or employee has a key that opens only their own space. Alameda Locksmiths designs, installs and maintains master key systems for apartment buildings, office suites, medical offices, schools and churches across Alameda.

We map the property, group doors by access level, and pin every cylinder so the system works exactly as planned with no accidental cross keying. Systems can include a grand master for ownership, sub masters for departments or floors, and change keys for individual doors. We keep secure records so future additions fit the plan. Many customers combine this with our Keyless Entry Locks service and our Access Control Systems service.

For higher control we build master systems on restricted keyways so tenants cannot copy keys. When a master key is lost we can rekey the affected level without starting over.

Frequently Asked Questions

How many levels can a master key system have?

Most properties use two or three levels: change keys, master keys and a grand master. Larger buildings can have more.

Can tenants copy their keys?

On a standard keyway yes. If you want to prevent copies we build the system on a restricted keyway that only we can cut.

What happens if a master key is lost?

We rekey the cylinders on that level and issue a new master. The rest of the system does not need to change.

Can you add doors to an existing master system?

Yes. As long as we have the system records or can decode the existing cylinders we can extend it.

Is a master key system suitable for a small office?

Yes. Even a five door office benefits from one owner key and individual staff keys.
