Step 1
Write down the model and brand of your current home locks. Take the information with you to purchase replacement locks. Buying a different brand or model may require the door be re-drilled for the lock to line up and operate properly.
-
Step 2
Use a screwdriver to remove the screws securing the lock to the door and pull the front and back pieces of the lock apart. Remove the screws from the latch plate and pry it off the door with the flathead screw driver. Slide a screw driver through the latch mechanism still in the door; use it to carefully push the assembly out of the door.

Step 3
Insert the new latch mechanism, align the plate and clearly mark its position with a pencil. The latch plate must be positioned flush with the door for the lock to operate properly. Take out the mechanism and use your chisel to cut a 1/16 inch bed for the latch plate. Reinsert the latch assembly and screw the plate in place.

Step 4
Slide the screws through the new lock and into the latch mechanism; align the other side of the lock to fit. Tighten in place with the screwdriver.

Step 5
Pry the old strike place off the door frame with a screwdriver after removing the screws. Place the new strike plate and screw it in place. Close the door and use the key to ensure the lock operates correctly. Repeat the process to replace the rest of your home locks.
