A lock for securing a door is provided, the lock includes a housing configured to be mounted on a door, a locking member movable between locked and unlocked positions, a core with a keyway and configured to turn relative to the housing to cause the locking member to move between the locked and unlocked positions, at least one optical source configured to emit an electromagnetic radiation signal at an object in the keyway, at least one optical detector configured to detect at least a portion of the electromagnetic radiation signal, a memory configured to store at least one authorized key characteristic, a motor configured to control movement of the locking member between locked and unlocked positions, and a processor that determines at least one sensed characteristic of the object in the keyway based at least in part on the electromagnetic radiation signal.

A cover for a key is disclosed. The cover includes: a first wall; a second wall opposite to the first wall; and an outer wall extending between the first wall and the second wall, the outer wall defining a pair of slots extending therethrough, the slots being positioned opposite to each other on the outer wall, wherein the first wall, the second wall, and the outer wall define a closed chamber for receiving a bow of the key and an opening to the chamber.

A method of identifying a specific key amongst a bundle of keys requires a plurality of keyhole tags and a plurality of key sleeves. Each of the keyhole tags includes a wireless transmitter. Each of the key sleeves includes a wireless receiver and at least one notification device that is associated to a corresponding tag. The method begins by broadcasting an identification signal with the wireless transmitter for each of the plurality of keyhole tags. The method then positions the plurality of key sleeves adjacent to a desired tag from the plurality of keyhole tags. The method then receives the identification signal for the desired tag with the wireless receiver for each of the plurality of key sleeves. Finally, the method actuates the notification device of a specific sleeve from the plurality of key sleeves, if the corresponding tag for the specific sleeve is the desired tag.
