Step-by-Step Guide

Step 1: Remove the Door Handle

Start by removing the screws that secure the door handle. Use your flathead or Phillips screwdriver, depending on the screws’ type. Once removed, detach the handle carefully.

Step 2: Access the Lock Cylinder

With the handle removed, you should be able to see the lock assembly. Locate the retaining screw that holds the lock cylinder in place and remove it.

Gently pull the lock cylinder out from the door. If it seems stuck, you may need to wiggle it gently or use pliers to help pull it out.

Step 4: Measure the Old Cylinder

Before purchasing a new cylinder, measure the old one to ensure you get the correct size. Measure the length from the center of the mounting hole to the ends of the cylinder.

Step 5: Install the New Lock Cylinder

Insert the new lock cylinder into the door, ensuring it fits snugly. Once in place, replace the retaining screw to secure it.

Step 6: Reattach the Door Handle

Align the door handle back into place and secure it with screws. Ensure it operates smoothly before closing the door.
