Claim 8:
9. A method for controlling a lock actuator of a safe, the method comprising:
emitting, from a transmitter, a light into a safe toward a receiver when a user attempts to lock a mechanical or electronic lock of the safe, the receiver configured to receive the light and generate an output signal, wherein the light is emitted within the safe in such a way that if an item is located within the safe the item blocks the light from being received by the receiver;
receiving, from the receiver at a processor, the output signal generated by the receiver, wherein when the receiver receives the light emitted from the transmitter the output signal indicates no item is inside the safe; and
determining, in the processor, whether an item is inside the safe, wherein the processor disables the lock actuator from locking the safe when the output signal indicates no item is inside the safe.
