For more infomation on locking faults on PVC doors please see this page -
A common type of door fitted to homes in the Macclesfiled and Stockport area is the uPVC multi point type. Most faults will require a locksmith to attend, but somtimes the householder can diagnose the fault
There are several reasons why your uPVC door could be failing to lock correctly:
If the handle has been feeling a bit stiff and the key wont fully turn any more, chances are that your upvc door locking bolts are not fully throwing because the door is out of alignment. This can be caused by swelling and contracting of the upvc door at differing temperatures or from general wear and tear on the upvc door due to repeated slamming or hanging on the door itself. This can often be remedied by adjusting the hinges of the door to re-align the keeps in the frame. once the lock is operating smoothly without obstructions the key will turn.
You can get similar symptoms due to debris in the upvc door frame preventing the door from shutting true. Regular cleaning of dirt and stones out of the frame will prevent this.
PVC door will only lock from one side…
If you find that your upvc door only seems to lock from one side of the door and the other will not allow the key to turn, then you will need a replacement lock barrel.
If when you lift the handle, and you turn the key to lock, you are unable to remove the key. This is caused by the central cam of the lock cylinder slipping out of alignment. General causes seem to be due to worn keys and lock components often as a result of heavy use and substandard quality locks,
You will need to call your local locksmith to replace the cylinder with a new one of correct size.
This is a relatively quick job if there are no other complications.
Handle is spinning all the way round, not opening the door…
This is often the aftermath of not getting your upvc door adjusted when it has been feeling stiff.
Prolonged forcing of the handle puts massive strain on internal parts and eventually they WILL break!
You have broken the spindle inside the lock back box and will need either a replacement backbox or entire locking unit, depending on the type of multipoint lock fitted.
You will need to call a local Wilmslow locksmith to open the upvc door and order the new parts which can be pricey therefore it is important that you get your door adjusted when early symptoms of stiffness occur.
