How to Change a Door Lock in Steps How to Change a Door Lock in Steps

If your door lock breaks, you should be able to change it yourself without calling in a locksmith. All you need to be able to do is tell right from left and top from bottom.

Tools and Things You Will Need

  • Replacement door handle
  • Phillips screwdriver, manual or electric
  • Flathead screwdriver

Step 1 - Removing the Old Handle

Begin by locating the screws on the handle. If you don't see any screws, look for a slot on the underside of the handle. Use the flathead screwdriver to push in the slot and pull the old handle off. Once you have the handle off, you will see the metal facing plate on the unit that is covering the working part of the door handle. Using your screwdriver, push it in the slot where it butts up against the door. This should pop it off. Now you can see the screws. With the drill or screwdriver remove all the screws. Now, on the inside of the door facing remove the plate that is holding the handle place and pull the door handle out. To do this you need to remove both sides, and they should just pull apart.

Step 2 - Removing the Striker Plate

At the point where the door latches, there is a plate with a hole in it. You need to remove this plate as your new handle comes with a strike plate of its own. Observe how the door handle is set in so when you replace it you remember how to do it. If you don't, you will have to remove the knob and do it again.

Step 3 - Installing the New Door Handle

So far so good. Now take all the new parts out of the packaging and make sure you have the screws and all the parts to put it back together. First, install the new striker plate. Everything should work without having to put new holes unless you change the style of your door knob.  Now put the door handle together in the opposite way that you took it apart. Put the two pieces together and then screw in the door piece.  Then screw in the new door knob piece and tighten it with your screwdriver. After you have done this pop the plate over the mounting screws. This should only take a half twist and it will go on. Now replace the knobs and make sure they are turning the right way. Finish the last screws or pop the knob on whatever way it attaches. Test the lock and you are done.
