Changing a door lock is necessary when you move into a new home, get a new roommate, or experience a burglary. It can also be a quick, easy way to switch up your door’s look. If you love your existing knobs and don’t want to replace the entire set, you can simply rekey the lock with a kit labelled for its brand.
