1. A method of detecting a lock state of an electronic lock, the method comprising:
by an electronic key comprising a hardware processor,
determining that the electronic lock is in an unlocked state;
storing an identifier of an unlock event based at least in part on determining that the electronic lock is in the unlocked state;
transmitting a first signal to the electronic lock indicating that the electronic key is requesting a response from the electronic lock; and
storing an identifier of a lock event based at least in part on not receiving a response to the first signal.
