• In case of multi-point locking systems, check that all locking points are addressed.

Tools & Materials

Step-by-Step

1. Identify the type of lock and the failure – check for loose screws, misalignment, or worn components.

2. Secure the window with temporary support to prevent accidental opening during repair.

3. Remove the failed lock – gently unscrew and detach the mechanism from the frame or sash.

4. Clean the area – remove any debris, old adhesive or corrosion which may affect the new lock’s fitting.

5. Fit the replacement or repaired lock – align with the existing holes and secure with appropriate screws.

6. Apply lubricant if necessary to ensure smooth operation, then reassemble any additional locking points.

Completion Checks

• Lock operates smoothly with no binding or excessive play.

• All components are secure with no loose screws or misalignments.

• The window is safely secured and the repair meets operational standards.

When to Call a Pro Instead
