Common UPVC Door Lock Issues: What Can Go Wrong?


  • Problem #1: The UPVC door won’t open. Expert help is usually required when a UPVC door won’t open even when it has been opened or the locking mechanism is stuck. A good locksmith will be able to tell if it’s the gearbox or the door. If the lock is sticky or stiff when the door is open then it’s a lock issue. If not then it’s the door itself.
  • Problem #2: The locking mechanism on UPVC doors sticks shut. It’s usually more complicated when the locking mechanism only engages when the door is closed. This can be due to a loose strike plate, misalignment, or heat expansion of the door. Our experienced locksmiths can diagnose and fix these problems.
