ABSTRACT:
A door lock indicator device is disclosed. The door lock indicator device can include a rotatable portion, a lock status display, and a switch (e.g., a button). The rotatable portion can define an opening shaped to receive a key blade. The door lock indicator device can be installed on a face of a door lock with the opening aligned with a keyhole of the door lock. Rotating a key blade within a keyway of the door lock can cause the rotatable portion to rotate with the door lock's cylinder. The lock status display can include a first indicator light and a second indicator light. Activating the switch can cause the lock status display to indicate a direction of a most recent rotation of the rotatable portion and/or a locked or unlocked status of the associated door lock.
