The locking strip on your UPVC door is one of the few moving parts of your door. It is the part that suffers the stresses and strains of repeated daily use, and as such will wear out eventually.

Symptoms may include

Dropped handles

Stiff resistance when opperating

Not all the bolts are moving when the handles are opperated

If these problems are not addressed then the lock will eventually fail. If you are lucky it will fail in the open position. If you are unlucky it will fail in the locked position locking you in or locking you out. It will always pick the most inappropriate time to do so.

There is no need for a new door. If you are otherwise happy with the condition of the door then the locking strip can be replaced with a like for like replacement or upgraded to a higher security specification for added piece of mind.
