Lockfit specialise in Upvc doors. If you experience problems with your uPVC door and are not familiar with uPVC door locking mechanisms it’s recommended to call a locksmith and do not extract the locking mechanism by yourself.


There are several different manufacturers that make UPVC door locks and mechanisms. Whilst there are many different variants and designs, they all work using the same essential principle.


The kind of lock known as a “multi point locking mechanism” is not unique to uPVC doors: it also sometimes features on wooden composite doors. When this device malfunctions in the closed and locked position, it can lead to other issues.


Usually there are tell-tale signs that the system is going to malfunction.

How to tell if the system may be beginning to fail include:


The handle becoming difficult to operate. It may need additional pressure at the end of the turn(while you lift it).
The lock is not functioning properly, becoming stiff or making a “click” sound.
The handle becomes wobbly and loose or spins completely


These indications can point to a number of different things. Hopefully, the problem is something relatively simple such as the door alignment has been knocked slightly. But it could be a more serious issue where one or more of the moveable internal parts has frozen up, seized or broken. Or possibly the problem is within the locking euro cylinder.

How does a Multipoint Lock Work?


Multipoint locks usually work in identical ways, no matter how many locking points it may have and what type they are. They could be simple rollers, large hooks and bolts or a combination of the two types. Mechanisms in which you need to lift the handle that activates the locking points operates are the most frequently used mechanisms. In these types of system the entire mechanism is locked into place while enables a simple turn of the key in the cylinder to lock and unlock the uPVC door.
