# How to Reverse a Door Lock
When installing a door lock, the keyhole should be positioned on the outside of the door so you can unlock the door with a key from the outside. However, the two sides of a lock assembly are a mirror image of one another, and any lock can be installed with the keyhole facing either direction. Any key-in-knob or deadbolt lock can be easily reversed if it has been installed improperly or you need to change the direction of the keyhole for any reason.
