1. A portable entry system comprising:

  • (a) an electromechanical lock comprising;

    a locking bolt moveable between an open position and a closed position;

    an electromagnetic device having an engaged state and a disengaged state, the electromagnetic device operably attached to the locking bolt for preventing the locking bolt from being moveable to the open position when the electromagnetic device is in the engaged state, and allowing the locking bolt to be moveable to the open position when the electromagnetic device is in the disengaged state;

    a circuit board electronically connected to the electromagnetic device;

    computer memory attached to the circuit board capable of storing at least one lock security code;

    a processor attached to the circuit board and in communication with the computer memory, the processor capable of comparing a received lock security code to the at least one lock security code stored in the computer memory and capable of sending a signal that causes the electromagnetic device to change between the engaged state and the disengaged state;

    at least one communications channel capable of sending a code to the processor; and

    at least one power channel in electrical communication with the circuit board; and

    (b) a receiving receptacle including at least one power contact and at least one data communications contact, the at least one power contact operably connected to the at least one power channel and the at least one data communications contact operably connected to the at least one communications channel;

    (c) a portable entry device removably detachable from the receiving receptacle, the portable entry device comprising;

    a housing including at least one data communications contact and at least one power communications contact;

    a power supply contained within the housing, the power supply in operating communication with the at least one power communications contact;

    a processor contained within the housing having computer memory in operating communication with the at least one data communication contact, the computer memory storing an authorized user security code and the lock security code;

    a user interface operably attached to the housing and in operating communication with communications channel;

    wherein when the portable entry device is placed in the receiving receptacle, the at least one data communications contact and the at least one power communications contact are in operating relationship with the communications channel and power channel such that when an authorized user enters the authorized user security code in the user interface, the portable entry device microprocessor transmits the lock security code stored in the portable entry device to the electromechanical lock microprocessor for comparison, andfurther wherein if the lock security code received from the portable entry device matches the lock security code stored in the electromechanical lock, the electromechanical lock processor sends a signal to the circuit board causing the electromagnetic device to change from the engaged state to the disengaged state;

    (d) a handle member moveable from a first position to a second position after the electromagnetic device has changed to the disengaged state to move the locking bolt from the closed position to the open position.
