Lock Changes, Lock Replacement & Security Upgrades

• Real Locksmiths. Real People. Real Jobs.

Shaun and Jayden attended a property at RSA Island Centre, Enfield EN3, after a new tenant requested a lock change.

Having recently taken over the tenancy, the customer wanted to ensure that anyone holding keys from the previous tenancy could no longer gain access.

The existing lock was being replaced for security reasons rather than because of a mechanical fault.

The new tenant wanted control over who had access to the property.

✅ Existing euro cylinder removed
✅ Correct replacement cylinder size established
✅ New BS 1-star security cylinder installed
✅ Replacement cylinder correctly fitted to the door
✅ Previous keys no longer operate the lock
✅ Property security upgraded

The tenant now has a new security cylinder, correctly sized and fitted, ensuring keys from the previous tenancy can no longer operate the door.

When moving into a new property, you may not know how many copies of the existing keys are still in circulation.

Changing the cylinder is a straightforward way to prevent previous keys from operating your lock.

It's also important that replacement euro cylinders are correctly sized, as excessive protrusion can create a security weakness.
