1. A safe comprising:
a lock actuator configured to lock or unlock a mechanical or electronic lock of the safe;
a control system communicatively connected with the lock actuator, the control system comprising:
a transmitter configured to emit a light into the safe when a user attempts to lock the mechanical or electronic lock of the safe;
a receiver configured to receive the light emitted from the transmitter 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, wherein when the receiver receives the light emitted from the transmitter the output signal indicates no item is inside the safe; and
a processor configured to receive the output signal from the receiver and determine 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.
