Why does my uPVC door lock when I open it but not when I close it?
If the handle lifts and the key turns with the door open but not with it shut, the mechanism is usually fine and the door is out of line with the frame. The hooks, rollers or bolts are catching on the keeps instead of sliding in. A small adjustment to the keeps, rollers or hinges usually fixes it.
What are common uPVC door lock problems?
The most common uPVC door lock problems are a door that has dropped out of line with the frame, a failed gearbox, a damaged multipoint strip and a worn or wrong length cylinder. A lack of lubrication and changes in temperature can also stop a door locking.
How to fix a uPVC door that won't lock?
First test the handle and key with the door open. If they work open but not shut, the door is out of line and the keeps, rollers or hinges need adjusting. If they are stiff, floppy or jammed even when open, the gearbox or multipoint lock usually needs replacing, so stop and do not force it.
Can you replace the locking mechanism on a uPVC door?
Yes. The locking mechanism in a uPVC door can be replaced without changing the door, and often only the centre gearbox needs swapping. If the hooks, rollers or strip are damaged, the whole multipoint lock is replaced with one that fits the same measurements.
Why won't my uPVC door handle lift up?
A uPVC door handle that will not lift usually means the door is out of line with the frame or the gearbox is failing. If it lifts with the door open but not when shut, the door needs adjusting. If it will not lift or push down even when open, the gearbox usually needs replacing.
Why won't my uPVC door lock in hot or cold weather?
uPVC expands in hot weather and contracts in cold weather, and the Master Locksmiths Association says being just 1mm or 2mm out of alignment can stop a door locking. The fix is usually a small adjustment to the keeps, rollers or hinges, not waiting for the weather to change.
