Door Lock is Jammed/Stuck

This problem is usually one of two things usually but can be both.

1. Key won’t turn fully in lock

If the key goes in the lock and will not turn this means the lock is faulty or there is an alignment issue with the door & frame being out of alignment.

Why the key won’t turn

Common reasons this happens are usually because:

• The lock is worn or faulty, or there is a door alignment issue
• A cheap lock has been fitted
• General wear and tear
• Lock has been glued
• Something has been inserted into the lock

SOLUTION:

The lock will need to be replaced once the door has been unlocked & opened, a replacement can then be fitted along with new keys.

2. Keys goes in lock & turns but won’t open

UPVC/Composite Door

If the key goes into the euro lock and turns, and the door won’t open, this usually means the multi-point lock has failed or a security bolt or hook has jammed.

Why the lock won’t turn

Common reasons this usually happens are:

• UPVC Multipoint lock may need repairing or replacing
• Door and frame not fitting correctly or are out of alignment
• The handles have been forced up to lock and the delicate mechanism has broken
• General wear and tear

SOLUTION:

May need a new multipoint locking system and or door alignment.

uPVC Door Won’t Shut or Close

Why the door won’t shut

This is commonly caused by either:

• The strike receiver for latch part of the lock not being adjusted correctly or having worked loose and now not being set correctly
• The door trim rubber has moved & is not sitting properly stopping the door from shutting correctly.

Door or Window Lock is Damaged or Broken 

The most common issues you could be facing are:

1. UPVC Door/Window Lock Problem when lifting (floppy handle)

Why the handle is floppy when lifting

If your door/window lock is very ‘floppy’ when lifting this means the handle is usually due to a worn or faulty locking mechanism.

2. Keys Goes in but have to move key up and down

Why the key won’t work

When a key goes into a euro profile cylinder but you have to jiggle or pull key up or down, it is usually a sign of badly cut keys or a faulty or worn euro cylinder lock.
