Screwdrivers (flathead and Phillips)
Replacement door lock (matching your door type)
Tape measure
Pencil or marker
Lubricant (optional, for smooth operation)
Having the correct tools will make the replacement process quicker and safer.
Types of Door Locks
Common door locks include:
Euro Cylinder Locks – most common for uPVC and composite doors
Mortice Locks – often used in timber doors
Deadbolt Locks – provide extra security for external doors
The steps for replacement differ slightly depending on the type, so always check the instructions for your specific lock.
Step-by-Step Guide to Replacing a Door Lock
1. Remove the Old Lock
Unscrew the door handle if necessary
Remove the screws holding the lock cylinder or mortice in place
Carefully take out the old lock
2. Measure the Lock
Measure the old lock or cylinder to ensure the replacement fits
Note the type of key entry (single or double cylinder)
3. Install the New Lock
Insert the new lock into the door
Secure with screws, making sure the lock is aligned properly
Test the lock mechanism to ensure it operates smoothly
4. Reattach Handles and Accessories
Replace the door handle if it was removed
Make any adjustments so that the lock and handle work together
5. Test Security

Tips for uPVC Doors
uPVC doors often use euro cylinder locks, which are easier to replace than mortice locks. Key tips include:
Ensure the new cylinder is the correct size
Keep a spare key for all new locks
Avoid forcing screws into uPVC, as it can crack
