A security door latching mechanism and complementary receiver are arranged to be installed within a door and a complementary door jamb. In the preferred embodiment, the installation takes place in a vehicle and the latching mechanism can be installed either in the door or in the door frame or jamb. The latching mechanism includes a plunger shaft which is arranged to extend from the door jamb into the receiver, and is forcibly maintained in the extended position until retracted by an electrical current provided to an actuator. This actuator is spring-driven to keep the plunger shaft in an extended position until provided with an electrical power to retract the plunger shaft. A wedge-shaped guide forces the plunger shaft to slide to the recess when the door is being closed. It is necessary to constantly maintain the electric power to the actuator in order to keep the plunger shaft retracted.
