Master Key Systems
A master key system lets one key open several locks while each person's key only opens the doors they need. Restricted key systems stop keys being copied without your authority.
Who needs a master key system
- Offices with many doors and staff
- Shops, warehouses and schools
- Blocks of flats and HMOs
- Too many loose keys to manage
- Keys copied without permission
How we solve it
Your locksmith maps which keys should open which doors, then supplies and fits matching cylinders. With a restricted system, new keys can only be cut on your authority.
How your locksmith helps
- Step 1
Plan
The doors and who needs access are mapped out.
- Step 2
Fit
Matching cylinders are fitted across the site.
- Step 3
Issue keys
Keys are handed over and labelled to the plan.

Master Key Systems: common questions
Can you add doors later?
Usually, yes. A well-planned system can be extended with new cylinders keyed to the same plan.
What if a key is lost?
The affected cylinder can be changed without replacing the whole system.
How much will it cost?
It depends on the lock, the work and the time of day. Your locksmith will tell you the price before starting, and nothing goes ahead until you agree.
