uPVC door won't lock
First of all, check these three points:
- Is it hot or cold weather? In the peak cold or warm months, it's common for a uPVC door to expand in heat or contract in severe cold. Repeatedly wiping the door with a cloth soaked in warm or cold water will get it back to its natural state.
- Is there anything blocking the door frame? Check for any blockages on the outside of the door, as well as the frame of the doorway. The door may engage a lock at multiple points, so be sure to check all locking points are clear. Also, make sure that nothing is caught on the bottom edge of the door.
- Is the lock snib engaged? The snib is a button or switch that holds the locking bolt in or out. If the snib is engaged, release it to be able to lock the door.
