Master key systems

Master Key Systems in Harrow

One key that opens everything for you, while each tenant, member of staff or department only opens their own door. That’s a master key system, and it’s a tidy solution for landlords, HMOs, offices and small commercial buildings. I design and fit master-keyed suites across Harrow and the surrounding areas, sized to what you actually need.

Good for

Landlords and HMOs
Offices with staff-only areas
Small blocks and communal buildings
Shops with stockrooms
Anywhere you want controlled, tiered access without a fistful of keys

A pile of euro cylinder locks and their keys

How it works, in plain English

Every lock is keyed so it accepts both its own key and a single master key. So a landlord or manager carries one key for the whole building, while each occupant’s key only works their own door. You can add sub-masters (say, one key per floor) as it scales.

Done properly

A master suite is only as secure as its planning. I’ll map out who needs access to what before cutting anything, use quality cylinders, and give you a documented key schedule so you know exactly which key opens what. No call-out fee, and a fixed price agreed before I start.

We urgently needed someone to come out, and after contacting several locksmiths, Andrew was the only one willing to help at such short notice.

He arrived within just 30 minutes and managed to get the door open, allowing us to carry on with our work for the day without any further disruption.

Fantastic service, very professional, reliable and efficient. It's not often you find someone so willing to help at short notice. I would highly recommend Andrew to anyone needing a locksmith and would definitely use his services again. Thank you, Andrew!

 Trustindex verifies that the original source of the review is Google. Andrew was really excellent. Fixed the front door yale, and garden door locks, for a good price. Efficient, quick, came on time, communicated well. Gave very good advice about what needed to be replaced, and what did not, and explained why. I would definitely use him again. Always great to find a first class tradesman/woman.

 Trustindex verifies that the original source of the review is Google. Excellent service from Andrew. I could not unlock my garden gate it was stuck in the lock position. Called Andrew on the Wednesday and he visted the same day. New lock required, not an off the shelf lock so Andrew had to ordered it. The lock was delivered on the Friday and Andrew fitted it the same day. I'm happy with the service and will definitely use him again if needed.
