An electromechanical lock that can be mounted to an interior surface of a door or panel, on a cabinet, locker, furniture, or other storage device, can include a locking element such as a bolt, latch, or cam that can be translated between a locked position and an unlocked position by an actuator. A user interface can extend through a hole in the door or panel to provide a user terminal available to a user that can provide, for example, information or access to the lock. The user interface can have an adjustable backset to allow the lock to be retrofitted to a door or panel with a pre-existing hole from a previous lock, regardless of the backset of the pre-existing hole.
