uPVC doors are popular for good reason, but their multipoint locking mechanisms can develop problems over time, especially with heavy daily use.
A handle that feels loose or drops when you let go usually points to a worn gearbox inside the mechanism. This is a straightforward repair and does not usually require replacing the whole door.
If the door will not lock unless you lift the handle firmly first, the multipoint mechanism has likely dropped out of alignment. This is common and can usually be adjusted or replaced without needing a new door.
A door that has become difficult to close at all is often a sign the hinges need adjusting, rather than a problem with the lock itself.
In colder months, uPVC doors can also expand slightly, making locks feel tighter than usual. If a problem persists beyond a few days, it is worth getting it looked at rather than forcing the mechanism.
