Business locksmith services

Master key systems

One key for managers, limited keys for staff. We plan the hierarchy and rekey your cylinders to match.

High-security locks

Restricted-keyway cylinders that resist picking, bumping and unauthorised copying.

Panic bars and exit devices

Push-bar exit hardware installed or repaired on egress doors.

Keyless entry locks

Keypad, combination and electronic locks for staff doors and back offices.

Safes and file cabinets

Lockouts opened, combinations reset and cabinet locks replaced.

Office lockouts and lost keys

Entry for locked offices, then rekeying if keys are missing.

Key control that grows with your business

When staff change, keys walk out the door. A planned master key system lets you rekey a single cylinder rather than every lock in the building, and restricted keyways stop copies being cut at a hardware store. We map who needs access to which doors, then build the system around it.

Keyless and electronic options

Keypad and electronic locks remove the problem of lost keys altogether: change a code and the old one stops working. We supply and fit electronic, mechanical-combination and fingerprint models. Our guide to commercial keyless entry locks compares them.

Landlords and property managers

We rekey or replace locks after a tenant leaves, including after a lawful eviction once possession has been returned to you. Read how eviction lock changes work.

Mobile vans stocked for commercial work

Our vans carry common commercial cylinders, mortise and rim hardware, exit device parts and key blanks, so many jobs are finished in one visit. Larger installs are scheduled with you in advance. We accept all major credit cards for business accounts.

Frequently asked questions

Can you work after hours?

Our listed hours are seven days, all day, so we can often schedule commercial work before opening or after closing. Ask when you call.

Can you rekey a whole building?

Yes. We can rekey cylinders to a new master key system and provide a key schedule so you know who holds which key.

Do you install access control?

We install standalone keypad and electronic locks. For networked card-access systems, ask us first so we can tell you whether it suits our service.
