The majority of issues are caused by door alignment rather than lock failure. The most common causes reported across the industry are:

• Door misalignment
• Failed gearbox
• Handle droop
• Hooks or rollers not engaging
• Stiff or difficult key operation

Regular maintenance and adjustment can help prevent many of these issues.

This is usually caused by the door becoming slightly misaligned with the frame over time.

In many cases the hinges or locking keeps simply need adjusting to bring the door back into alignment.

A loose or drooping handle is commonly caused by worn springs, the spindle, or the internal gearbox mechanism.

The handle or lock mechanism may need replacing.

This is often caused by pressure being placed on the locking hooks or bolts due to door misalignment.

Re-aligning the door and lubricating the lock can usually resolve the issue.

A jammed lock is typically caused by a failed internal gearbox.

In most cases the lock will need replacing.

This is commonly caused by the door dropping slightly or the locking keeps moving out of position.

Adjusting the hinges or frame keeps will normally resolve this.

This usually indicates misalignment between the lock and frame keeps.

The door, keeps, or hinges may require adjustment.

This is often a sign of an internal gearbox failure inside the lock mechanism.

The lock may need replacing.

Over time, doors can naturally drop slightly due to regular use.

A hinge adjustment or toe-and-heel adjustment may be required to restore alignment.

Dirt build-up or worn rollers and hooks can cause stiffness. Cleaning and lubricating the lock with a PTFE silicone spray is recommended.

Worn components may also need replacing.

Internal wear within the lock mechanism can cause unusual noises. This is normally an indication that the lock should be replaced.

This can be caused by a broken or worn internal mechanism within the lock.
