Claim:
1. A locking system for unlocking a lockable device, the locking system comprising: a failsafe lockable device arranged to move between a locked state in which the lockable device is blocked from being activated and an unlocked state in which the lockable device is free to be activated, a computer processor connected with the lockable device and configured to receive a request from the lockable device to move the lockable device between the locked state and the unlocked state and to transmit a request signal for unlocking the lockable device, and an interface module in electronic communication with the computer processor and the lockable device, the interface module including an interface-module processor connected to the computer processor, a primary circuit connected to the interface-module processor, and a secondary circuit connected to the interface-module processor, and wherein the interface-module processor is configured to send a first set of electric signals to the primary circuit and a second set of electric signals to the secondary circuit in response to receiving the request signal from the computer processor, the primary circuit is configured to default to an inactive state and to move to an activate state if the first set of electric signals are equal to a first set of predetermined values, the secondary circuit is configured to default to an inactive state and to move to an activate state if the second set of electric signals are equal to a second set of predetermined values, the interface module is configured to block the lockable device from moving to the unlocked state if at least one of the primary circuit and the secondary circuit is in the inactive state, and the interface module is configured to allow the lockable device to move to the unlocked state if both the primary circuit and the secondary circuit are in the activated state.
