A self-powered electric lock comprising:

• a lock-bolt mounted for movement between locked and unlocked positions;
• a first engagement element having disengaged and engageable positions;
• an electric actuator having an output operative to move said first engagement element to the engageable position thereof;
• a manually operated rotatable member operatively coupled to said first engagement element in the engageable position;
• a lock-bolt drive mechanism coupled to said lock-bolt and to said first engagement element when said first engagement element is in the engageable position, said lock-bolt movable relative to said lock-bolt drive mechanism and said first engagement element;
• an electronic data input device electrically coupled with said electric actuator to cause said output to move said first engagement element to the engageable position thereof upon input of correct electronic input data to said electronic data input device;
• and
• an electricity generator operatively coupled to said manually operated rotatable member to generate electricity upon movement of said manually operated rotatable member, the electricity being used to power said electric actuator and said electronic data input device;
• wherein said manually operated rotatable member is usable by an operator to generate electricity and further usable to actuate said lock-bolt drive mechanism and retract said lock-bolt upon input of the correct electronic input data thereby placing said lock-bolt in the unlocked position.
