These are the faults we are called about most often. If any of these sounds familiar, the problem is almost certainly the lock mechanism or cylinder, not the door itself.

Handle has dropped and will not lift

The gearbox inside the mechanism has failed. If the door may still close, but cannot be double-locked, it is a serious security risk and you most likely need a upvc locksmith to help you with replacement parts or the entire mechanism repair. If your front door won’t lock, this is one of the most common causes of UPVC doors.

Door will not double-lock

The key turns once but will not engage the deadbolts of the upvc door mechanism. Usually, a worn or snapped gearbox cassette is inside the multipoint locking mechanism and can help with the locking points. Londoner Locksmith can assist with multi-point locking systems or any broken lock issue.

Key turns, but the door will not open

The spindle connecting the handle to the mechanism has sheared, or the mechanism itself has seized. You need to take care of any uPVC door security issue, and this is for sure an emergency. We can help with all situations and uPVC lock brands.

Door has locked itself shut from the inside

The auto-lock feature has engaged with no handle to disengage it, or the snib has been accidentally knocked. Common in flats and newer UPVC doors.

Handle feels loose or spins freely

The central spindle has worn or broken. The door may appear locked, but it is not secure. Our locksmiths are prepared to offer solutions fast. We can help with anti-snap locks or cylinder locks.

Door will not close properly

The multi-point hooks or rollers have drifted out of alignment with the keep. If the door is also physically stiff, dragging, or leaving gaps around the frame, the issue may be door alignment rather than the lock itself. See our UPVC door realignment page for more on that.

Most UPVC lock problems come down to the gearbox cassette inside the mechanism — the component that drives the hooks, rollers, and deadbolts when you lift the handle or turn the key. When this fails, we remove the old mechanism from the door edge and fit a direct replacement. The door, frame, and handle usually stay exactly as they are.

The job typically takes 20 to 40 minutes. We measure the mechanism on arrival and carry the most common sizes in the van, so same-day completion is the norm rather than the exception.

Mechanism replacement vs full lock change

In most cases, the mechanism alone needs replacing, which is both faster and cheaper than changing the whole lock. If the euro cylinder has also been damaged, for example, after a break-in attempt or a snapped key, we will replace it at the same time. We stock anti-snap euro cylinders as standard, which is the lock upgrade recommended by the Metropolitan Police and most home insurers.

Every UPVC door uses a euro cylinder and the oval barrel that the key goes into. Standard cylinders are vulnerable to a forced entry technique called lock snapping, where the exposed end of the cylinder is broken off with brute force in a matter of seconds. Upgrading to an anti-snap cylinder closes this vulnerability and is strongly recommended by insurers and the police.

We can fit an anti-snap cylinder at the same visit as a mechanism repair, usually adding only a few minutes to the job. Combining the two is the most cost-effective way to bring a UPVC door fully up to current security standards. 

Most UK home insurance policies require all external doors to be properly locked when a claim is made. For example, a UPVC door with a failed mechanism (one that cannot be double-locked) may invalidate a contents or buildings claim, even if the door appears closed. So, if your front door won’t lock or cannot be double-locked, getting it repaired is not just a security matter but a practical insurance one.
