Where’s the job?

Overview

• Fitting new locks for properties to boost security and update aesthetics.

• Skill level: 3 / 5 (requires accurate measurement, basic carpentry and hardware know-how).

• Typical duration: 2 – 4 hours depending on door type and lock complexity.

Safety First

• Ensure the door is securely supported when removing or fitting locks.

• For electronic or smart locks, disconnect power if necessary before installation.

• Wear safety gloves to avoid cuts from sharp edges, especially when handling old hardware.

• Always check that the lock fits the door thickness and backset measurements to ensure a secure fit.

Tools & Materials

Step-by-Step

1. Choose the correct lock type – traditional, multipoint, or smart lock – based on property security needs.

2. Gather all necessary tools and double-check measurements against the door’s specifications.

3. Remove the existing lock carefully, keeping any extra fittings if re-use is required.

4. Mark and, if required, drill new holes ensuring accurate alignment with the strike plate.

5. Fit the new lock into the door and secure it with the provided screws; check for smooth operation.

6. Re-assemble door handles, ensuring the key turns easily and the bolt aligns with the door frame.

7. Test the lock repeatedly to confirm reliable operation: insert key, check auto-latching and overall security.

Completion Checks

• Lock operates smoothly and key turns without force.

• Door and handle alignment are confirmed with no gaps or misalignment.

• All screws are tight and there is no wobble in the lock or door handle.

• For electronic locks, the battery and connectivity (if applicable) are fully operational.

When to Call a Pro Instead

If the door structure is old, or if specialised keying or electronic integration is required, consider calling a professional locksmith to ensure optimal security and compliance with local regulations.
