1. A method of preparing for discharge of an electric latch assembly, the method comprising:
determining whether the electric latch assembly is in an unlocked state;
in response to a determination that the electric latch assembly is in the unlocked state, monitoring a voltage of a battery;
comparing the voltage of the battery with a preset reference voltage at which a mechanical redundancy (MR) mode is to be activated;
determining a location of a smart key as being located inside or outside a vehicle; and
activating the MR mode by driving an MR motor installed inside the electric latch assembly in response to the voltage of the battery being less than or equal to the reference voltage.
