First, you need to remove your door handle

Follow the steps below to remove your handle.

Step 1

First, make sure the door you are working on is propped open or is secured safely, so this procedure is easier to complete without the worry of the door closing mid-operation.

Step 2

Begin by loosening the screws that are holding the handle in place. Composite door handles typically have two screws holding them in place, and they will be on the inside of the door for security. If you’re struggling to locate the screws, they will most likely be covered by caps for aesthetic purposes. Using your Phillips-head screwdriver remove both the top and bottom screws that are holding your handle securely to the door.

Step 3

Once you have removed the screws, both the outer handle and the interior handle will slide out together. Make sure you do this slowly and to keep hold of both outer and interior handles as you remove them. You don’t want to lose or damage any pieces in case they are needed again in the future.
