How a master key system works

Each lock is set up to open with two keys: its own individual key and a master key. Staff or tenants get keys that open only their doors, while the owner or manager carries one master key that opens everything. Larger systems can add sub-master keys, for example one for each floor or department.

Planning your system

We start by mapping who needs to open which doors. Then we rekey or replace the locks, cut and label the keys, and give you a clear record of which key opens what. When someone leaves, you can rekey just the doors they could open instead of the whole building.

Keep your keys under control

For tighter control, pair your master key system with high-security locks and restricted keys that can't be copied at a hardware store.

Pricing

The price depends on the number of doors, the locks and how the system is set up. Our $25 service call is added to the price of the job.

FAQ

Master key questions

Don't see yours? Call (510) 330-1498.

Can you build a master key system with our existing locks?

Often, yes. Many existing locks can be rekeyed into a master key system. We'll check yours and tell you which ones can stay.

Is a master key system less secure?

A well-planned system is secure. What matters is controlling who holds the master key, and using restricted keys where copying is a concern.

What happens when an employee or tenant leaves?

We rekey only the locks their key could open, so you don't have to change the whole system.

Do you work with property managers and HOAs?

Yes. We handle master key systems, rekeys between tenants and mailbox locks for buildings of all sizes.
