| 1. A lock device for engaging an object, said lock device comprising:
a lock including a deadbolt having a first end and a second end, which is structured to disengage from said object in a first
position and to engage said object in a second position;
a spring directly engaging and biasing the first end of said deadbolt toward the second position thereof;
an electro-mechanical apparatus including a stop member structured to engage said deadbolt, in order to hold said deadbolt
in the first position thereof; and
a wireless controller structured to receive a wireless signal and responsively energize said electro-mechanical apparatus,
in order to disengage the stop member of said electro-mechanical apparatus from said deadbolt and release said deadbolt to
the second position thereof,
wherein said lock is structured to receive a key,
wherein rotation of said key in a first direction in said lock drives said deadbolt from the second position to the first
position thereof, in order to charge said spring, and
wherein rotation of said key in an opposite second direction in said lock drives said deadbolt, when said stop member engages
said deadbolt, from the first position toward the second position thereof by overcoming a force from the stop member of said
electro-mechanical apparatus.
