If the handle lifts but the door won’t lock, or the key turns and nothing happens, the fault sits inside the Winkhaus locking system running down the edge of the door. Reach out to our locksmiths in Kensington, and we will identify the problem fast, day or night. We carry Winkhaus parts on the van, so most jobs are complete on the first visit, and there is no second appointment to fix.
Reach out to our team any time your Winkhaus door lock stops working as it should. Whether the door won’t latch or the key is stuck halfway, our locksmiths know these lock systems in detail and carry the parts to resolve it on the spot. Your local locksmith will be with you in about 30 minutes, no matter your location in Kensington.
A Winkhaus multipoint door lock is one long unit fitted into the edge of the door. Lifting the handle drives a steel rail upward, and that rail pushes several locking points out into the frame at the same time. Turn the key and the whole locking system is held in position.
On most Winkhaus multipoint locks you will find:
The key point is that the latch and the hooks operate separately. The latch keeps the door closed. The hooks and bolts only engage on the upward lift. If your door still shuts on the latch but will not lift, the latch is fine, and the fault sits in the rest of the locking system.
Everything you can see from outside is the faceplate: the long metal strip along the door edge, held on with a screw at the top and a screw at the bottom. The Winkhaus gearbox sits behind it.

You do not need any tools to identify which brand you have. Open the door and look along the edge:
Still not sure? Send a photo of the door edge and one of our trained professionals will identify it before we travel out. That way the right parts are already on the van when we arrive.
It lifts but the door will not lock – the internal cams have worn, so the hooks and bolts never fully engage
It feels heavy and needs real pressure – the first sign that the Winkhaus gearbox is wearing, and worth acting on early
The handle drops down on its own – the spindle has worn, which is separate from the main locking system and a cheaper repair
The key turns, but nothing moves – the cylinder cam is no longer driving the lock
The key will not turn at all – usually the cylinder rather than the Winkhaus unit itself
The door will not latch closed – the latch is not meeting the keep, normally an alignment issue
The lock only works with the door open – a clear alignment fault, and often no new parts are needed
We will always try to repair a Winkhaus door lock before we replace it, because a repair is cheaper and the lock is usually worth keeping. There are three outcomes:
– Adjustment. The lock is sound, the door has moved. We adjust the hinges and keeps, the hooks locate cleanly again, and the door lock operates as it should. No new parts.
– Partial repair. One component has failed. A worn spindle, a broken keep or a tired cylinder can each be replaced on their own, leaving the main lock in place.
– Full replacement. The gearbox has sheared, and the door lock cannot be recovered. We fit a matching Winkhaus unit from our range and test it before we leave.
Roughly half the Winkhaus call-outs we attend in Kensington fall into the first group. A lock that seems dead often only needs the door lifting back into position, and that is the first thing we check rather than the last. If we do fit a replacement, we keep a range of Winkhaus sizes in stock, so a failed door lock does not mean waiting days with the door unsecured while a part is ordered.
A large share of the Winkhaus repairs we attend need no new parts at all. Doors drop over time, frames move, and the hooks then strike the keeps instead of entering them. Every time you push up against that resistance, you put pressure on the gearbox, which is what eventually breaks it.
Here is what our locksmith checks, in order:
Simple guidance for anyone reading this page: if you have to pull or lean on the door to get the key round, stop using force and call us. Force is what turns a free adjustment into a full lock replacement.
Winkhaus units last well when they are maintained, and a few minutes of care extends the working life of the lock considerably:
If you would rather not do it yourself, we can adjust and lubricate the lock as part of any visit.
If the gearbox has genuinely failed, the replacement has to match your door exactly. Winkhaus supply a wide range of door lock configurations, so we measure properly and take the measurements below before we quote:
Get one measurement wrong, and the unit will not fit. That is the usual reason a self-fitted replacement stalls halfway through with the door standing open. We measure on site, then supply and fit the right door lock from our range in stock.
Winkhaus multipoint locks are not limited to the front door.
Winkhaus is not only a door lock company. The same business supplies window hardware fitted across London, built the same way as their door systems: several locking points driven by one handle. Where it has stopped operating properly, we can adjust or replace that hardware as well.
Winkhaus have also developed electric and keyless locking systems, designed around access control for flats and small business premises. If your building uses a Winkhaus electric system and a unit has failed, contact us, and we will advise on what can be repaired and what needs replacing.
Winkhaus is a German family company with a long reputation for engineering quality, and their locking systems are specified on mid to high-spec composite doors across Kensington. The materials are good, the tolerances are tight, and the brand record of innovation in door and window hardware is a large part of why so many installers fit them.
That same precision is why alignment matters so much. A Winkhaus lock is designed to operate within fine tolerances, and a door that has dropped a few millimetres will wear one out faster than a cheaper lock would.
We aim to reach your Kensington property in about 30 minutes:
Contact us with a photo or a short description, and we will give you honest advice on the likely cost before we travel.
Short answers to what customers ask us most about Winkhaus repairs.
Many can be repaired. Alignment faults and worn keeps need no new unit at all. Once the gearbox has sheared, replacement is the reliable solution.
No. The lock slides out of the door edge and can be replaced without touching the door or frame.
In most cases, yes. We carry the common sizes and can source specific variants, usually the same day.
Yes. If you are locked out or the door will not secure, we treat it as an emergency call-out with a 30-minute response target, 24/7.
Yes. Contact our team for assistance with windows as well as door lock work. We will also fit the parts professionally.
