Commercial Locksmith FAQs
Can you attend a commercial lockout urgently?
Yes, 24 hours a day. When you call we ask for the premises address and your authority to give access, then give you an honest arrival estimate. We open the door with as little damage as possible and make sure the premises is secure before we leave.
What is a master key system?
It is a set of locks where each person’s key opens only the doors they need, while a master key opens many or all of them. It suits offices, shops with staff areas and managed buildings. We plan it around your doors and roles and keep a record of every key issued.
How much does a master key system cost?
It is priced per door, because each door needs a new cylinder from the same restricted key system, plus the keys for each person. We survey your doors, agree who needs access to what, and give you a fixed written price for the whole system before anything is ordered.
Can you change office locks when staff leave?
Yes. When staff leave or keys go missing, we change or rekey the affected locks so the old keys stop working, then issue new keys with a record of who holds them. We can work out of hours so the change does not interrupt your working day.
Can you fix panic bars and fire exit hardware?
Yes. We repair, adjust and replace panic bars and push pads so exits open easily from inside. The responsible person for the premises still owns the fire risk assessment, and we will tell you if any exit hardware looks worn or unsuitable for the door.
Do you work with letting and managing agents?
Yes. Letting agents, managing agents and housing providers use us as their regular locksmith across all their properties. You get one contact, written quotes for approval, job notes after each visit and key records, which keeps owners and tenants informed without extra admin.
Do you work on safes, alarms or CCTV?
No. We work on door locks, master key systems, exit hardware, shutters, gates and cabinet locks. We do not open or service safes, and we do not install alarms or CCTV, so we will point you to a specialist if you need those.
