How To Change Door Locks:

*Remove the screws from the old-lock on the inside of the door: Use a head screwdriver to unfasten the two or three screws located on the inside knob plate. After, remove each side’s door knob by pulling them away from the door. If your knob or lock has no screws on it, insert a paperclip into the small hole on the side of the doorknob to release the knob latch and allow you to pull off the knob.

*Choose a desired lock or lock of the same brand that fits your door: After removing the knobs, measure the diameter of the lock’s hole and the distance from its center to the edge of the door. Check your current lock’s brand and buy a lock that matches it and fits the hole’s dimensions. In fact, you can find a new lock that meets the measurements you took at a home improvement store or online.

*Remove screws that secure the latch at the edge of the door: The latch is the final piece of lock equipment you need to remove. So, unfasten the two screws that hold the latch plate in place then slide out the latch from the opening in the side of the door.

*Wrap a cardboard template around the door edge: Any store-bought lock will come with a cardboard template that shows you exactly how the lock will fit onto the door. So, place this template over the hole in your door and make sure that everything matches up. Incase the template does not match up exactly with your hole, then you bought the wrong lock and you consider making a return for new lock that fits your door.

*Place the new latch into place: Start installation by sliding the new latch into the opening on the edge of the door. Drive the new screws through the holes in the latch plate and into the door edge to secure the latch.

*Put the door lock together: Place the outside knob (the one with the keyhole) and the inside knob on their respective sides then slide them through the lock hole towards each other. In fact, they should meet in the middle and connect. Additionally, don’t force them together but instead allow them to slide together easily. After, drive screws into the holes on the inside door knob plate to finish putting the lock back together.
