GU four-roller uPVC door lock replacement in Tickhill

We attended a property in Tickhill, Doncaster, to replace a faulty GU four-roller uPVC door lock. The internal door’s multipoint locking mechanism had failed, leaving the customer unable to operate the lock correctly.

As experienced Tickhill locksmiths, we regularly repair failed GU locking mechanisms on older uPVC doors.

Replacing the faulty GU 35mm four-roller mechanism

After inspecting the door, we identified a failed GU 35mm four-roller multipoint locking mechanism.

Fortunately, we had the correct genuine replacement on hand. We replaced the complete mechanism like-for-like, keeping the original locking arrangement.

Replacing a faulty lock and realigning the door can restore reliable operation without the cost of a new uPVC door.

New gold Brisant Sweet handles and euro cylinder

The customer also wanted to improve the door’s appearance because the original gold handles looked worn.

We completed the following work:

• Replaced the failed GU four-roller locking mechanism.
• Fitted new gold Brisant Sweet door handles.
• Installed a new euro cylinder supplied with five keys.
• Realigned the door for smooth locking and operation.

The new gold handles gave the door a smarter appearance. Meanwhile, the replacement mechanism and door alignment restored smooth operation.
