Step 2: Remove the Current Door Lock

Once you have taken measurements, it is time to remove the existing door lock assembly. Using a screwdriver or drill, unscrew all mounting screws from the inside of the door and carefully take out the entire unit.

If possible, take a picture of the setup for reference when installing the new door lock. While removing the lock, also check for any damage to the door frame and make necessary repairs if needed.

Step 3: Purchase a New Door Lock

Using the measurements you have taken, purchase a new door lock assembly that matches your current setup. Be sure to buy all components such as the faceplate, latch, and deadbolt separately – these parts are usually sold individually.

Additionally, check the installation instructions for the specific product before finalizing your purchase. Make sure to stock up on extra screws and any additional materials for installation.

Step 4: Install the New Door Lock

Now that you have all the necessary components, it is time to install your new door lock! Using a screwdriver or drill, secure the faceplate and latch/deadbolt into place by following the manufacturer’s instructions.

Make sure to use a level when drilling in the screws to ensure that everything is level. Finally, if necessary, use wood shims to fill in any gaps around the door lock for a better fit.

Step 5: Test and Secure Your Door Lock

After you have installed the new door lock, test it out before finalizing your project! Check that the latch and/or deadbolt are working correctly and that the door locks securely. Additionally, check how the handle feels when opening or closing it – if it is too stiff or loose, you may need to adjust the screws accordingly.
