Everything You Need to Know Before You Call
How do I know if I need to change my commercial locks?
You should consider a lock change if you’ve experienced a break-in, lost keys, employee turnover, tenant handover, or outdated locks that may not meet modern insurance requirements.
What types of locks do you replace?
We replace a full range of commercial locks: euro cylinders, mortice locks, digital keypad locks, shutter locks, and high-security deadlocks — always using insurance-approved components.
Can you replace locks outside of normal business hours?
Yes. We operate 24/7 for emergency lock replacements, with fast response across London and the surrounding areas. Ideal for break-ins, evictions or lost keys.
Can you upgrade locks to meet insurance standards?
Absolutely. We install BS3621 mortice locks, TS007 3-star cylinders, and PAS24-rated solutions that meet or exceed commercial insurance standards.
Do I need to change the whole lock or can you rekey it?
That depends on your lock type and security needs. In many cases, rekeying is a cost-effective option, but we’ll advise on the best route during our on-site assessment.
What businesses do you typically work with?
We work with offices, retail stores, warehouses, healthcare facilities, and landlords of commercial properties — from single-site operators to multi-location portfolios.
