Handle won't lift, the key won't turn, or the door won't lock? A replacement multipoint lock fixes most of these faults on uPVC and composite doors. A multipoint lock is the long strip in the edge of the door: a central gearbox with extra hooks, rollers or deadbolts above and below it that lock into keeps on the frame. We stock replacement multipoint door locks from Yale, Winkhaus, GU Ferco, Fuhr, Avocet WMS, ERA, Avantis, Mila and Fullex.
A multipoint lock replacement has to match the old lock: backset, PZ centres, faceplate and the position of each locking point. If only the middle has failed, a replacement gearbox may be all you need.
From the edge of the faceplate to the centre of the keyhole. Most locks in our range are 35mm; 45mm and 28mm are also available.
From the centre of the handle spindle to the centre of the keyhole. 92mm is the most common; we also stock 62mm and 70mm PZ locks.
Measure the width of the strip on the edge of the door (usually 16mm or 20mm) and its overall length from end to end.
Count the hooks, rollers and deadbolts and measure each one's position from the centre of the spindle, so they line up with your keeps.
Single spindle: both handles work the latch. Split spindle: the outside handle is disconnected, so the door can't be opened from outside without the key.
Look on the faceplate and gearbox for a name or part number, such as Yale Lockmaster, Winkhaus Cobra, GU Ferco, Fuhr 856 or ERA Saracen.
If the strip, hooks and rollers are in good condition and the fault is in the middle (the handle drops, the latch sticks or the key won't turn fully), a replacement gearbox is usually the cheaper repair. Replace the complete multipoint lock if the strip is bent, the locking points are worn or broken, or no matching gearbox is available.
Many locks combine them, for example 2 hooks and 2 rollers, or 4 rollers. Match the type and position of each point to your existing keeps, or replace the door keeps to suit the new lock.
With the door open, remove the handles and the cylinder (undo the long screw in the edge of the door, level with the keyhole). Undo the screws along the faceplate and slide the old lock out of the edge of the door. Fit the new lock the same way round, refit the screws, cylinder and handles, then check it locks smoothly with the door open before you close it.
Usually, yes, with a screwdriver and the right replacement. The new lock must match the backset, PZ centres, faceplate and locking-point positions of the old one.
No. Multipoint locks vary in backset, PZ, faceplate width and length, and in the type and position of the locking points. Match all of these, or send us photos if you are unsure.
Most composite doors use the same kinds of multipoint lock as uPVC doors, sometimes with a 45mm backset. Measure in the same way.
Only if they are worn or don't fit. Your handles must match the lock's PZ, and you can reuse the cylinder if it is in good condition. See our door cylinders and door handles.
