LockStars 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 LockStars and do not extract the locking mechanism by yourself.
There are many manufacturers that produce uPVC door locks and mechanisms. While the designs may vary, they all operate on the same basic principle.
The “multi-point locking mechanism” isn’t exclusive to uPVC doors — it’s also found on wooden and composite doors. When this type of lock fails while closed and locked, it can cause additional problems.
Often, there are warning signs indicating that the system may soon malfunction.
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 warning signs can indicate several potential issues. Sometimes it’s a simple problem, like the door alignment being slightly off. Other times, it could be more serious, such as one or more internal moving parts being frozen, seized, or broken. The issue might also lie within the locking euro cylinder itself.

Multipoint locks generally function the same way, regardless of the number or type of locking points. These points can be simple rollers, large hooks, bolts, or a combination of both. The most common systems require lifting the handle to engage the locking points, allowing the lock to secure fully. Once engaged, a simple turn of the key in the cylinder locks or unlocks the uPVC door with ease.
