Step 1. Remove the old lockset. The knob on the inside of the door is usually held in place with a small clip. This is located on the side of the sleeve that extends from the knob to the flange on the door surface. To release this clip, just push it into the flange with a screwdriver or an awl. Then pull off the knob.

Step 2. Remove the flange next. These are usually snapped in place over the lock mechanism underneath. To remove one, just pry it off with a screwdriver pushed into a slot designed for it. Other flanges are held by small spring clips. By pushing down on the dip with a screwdriver, the flange can easily be pulled off with your fingers.

Step 3. Once the flange is off, the lock mechanism will be accessible. The two sides of the lock are joined together by two screws. Remove these screws and take the lock components out of the lockset hole in the door.

Step 5. Install the new bolt assembly and make sure that the screws in the bolt plate are driven tightly into the door. Separate the lock halves and slide them together with the door and bolt assembly sandwiched between.

Step 4. With both sides of the lock removed, the lock bolt can be taken out. Remove the screws that hold the bolt plate to the edge of the door. Then pull out the bolt mechanism.

Step 6. While holding one side of the lock against the door, maneuver the other side of the lock so the screws fall in the slots made for them. Once the screw heads have cleared the slots, tighten the screws so both halves of the lock are tight against the door. Install the new knobs and new strike plate.
