Is your window jammed, stuck shut, or refusing to lock properly? These are signs of a failing window locking mechanism. At Locksmith in Coventry, we offer fast, professional window mechanism repairs and replacement in Coventry, restoring full function and security to your windows—without the cost of full replacement units.
Broken or seized window gearboxes
Damaged window locking strips
Worn-out espagnolette mechanisms
Faulty shootbolts and multi-point locks
Stuck, misaligned or stiff window hardware
A faulty or broken window mechanism can affect both your home’s security and energy efficiency. Here are the most common signs to look out for:
If the handle turns but the window doesn’t lock, or the locking points don’t engage, the internal mechanism (gearbox or espagnolette) may be broken or misaligned.
Windows that are stuck shut or won’t open fully often indicate a failed mechanism or broken gearbox. Forcing it can cause further damage.
If the handle turns loosely or spins without resistance, the internal locking mechanism may have snapped or become detached.
When your window doesn’t sit flush in the frame, feels wobbly, or leaves gaps, it can be a sign the mechanism isn’t pulling it tightly shut.
Gaps caused by a faulty mechanism can lead to cold draughts, water ingress, and higher energy bills due to poor insulation.
Unusual noises when turning the handle or opening the window can mean the gears or locking points are worn or damaged inside the mechanism.

The window mechanism, often called a gearbox or locking strip, controls the locking and movement of the sash. Over time, it can wear out, seize, or break—causing the window to jam or fail to lock securely.
Yes. We work with all major types of mechanisms including:
Espagnolette gearboxes

We service uPVC, aluminium, and wooden frames.
Most repairs or replacements take 30 to 90 minutes. We aim to carry out all work on the first visit with high-quality replacement parts.

Absolutely. We service homeowners, landlords, letting agents, offices, care homes, schools, and retail premises throughout Coventry and surrounding towns.
Proper maintenance can extend the life of your window’s internal locking mechanism. Here’s how to care for it post-repair:
Use a silicone-based spray (not WD-40) every 6–12 months on the internal mechanisms and locking points for smoother function.
Keep the window channels and tracks clean from dust, dirt, and debris to avoid blockage or excess strain on the mechanism.
Open and close windows fully every now and then to ensure everything moves smoothly. If you notice stiffness or resistance, don’t force it—call us for a quick check.
If the mechanism becomes stiff, misaligned, or fails to lock properly again, contact us straight away. We offer follow-up support and warranty on parts and labour.
