Abstract
A door lock device includes a lock having a deadbolt with a first end and a second end. The second end is structured to disengage from an object, such as a portion of a door frame, in a first position and to engage the object in a second position. A spring directly engages and biases the first end of the deadbolt toward the second position thereof. A solenoid includes a plunger structured to engage the deadbolt, in order to hold the deadbolt in the first position thereof. A sensor is structured to sense at least one of the first and second positions of the deadbolt. A wireless controller is structured to receive a wireless signal and responsively energize the solenoid, in order to disengage the plunger of the solenoid from the deadbolt and release the deadbolt to the second position thereof.
