Electronic lock state detection systems and methods

An electronic key comprising:

• a memory configured to store computer-executable instructions;
• and
• a hardware processor in communication with the memory and configured to execute the computer-executable instructions to at least:
• transmit an unlock signal to an electronic lock that is mated to the electronic key;
• receive a confirmation signal indicating that the electronic lock is in an unlocked state;
• store a first time value corresponding to an unlock event time associated with the unlocking of the electronic lock;
• transmit a first heartbeat signal to the electronic lock;
• receive a response to the first heartbeat signal from the electronic lock;
• determine based at least in part on the response to the first heartbeat signal that the electronic lock remains unlocked;
• transmit a second heartbeat signal to the electronic lock;
• determine based at least in part on not receiving a response to the second heartbeat signal that the electronic lock is in a locked state;
• and
• store a second time value corresponding to a lock event time associated with the locking of the electronic lock.
