A keyless locking mechanism is activated by a remote unit which transmits coded signals to an electromechanical door lock device. The electromechanical device components are configured for secure mounting within the void or hollow portions of existing door locking apparatus. A sensor in the outer doorknob receives and forwards the coded signals to a processor which compares them with a predetermined stored signal. If an acceptable comparison is made, the processor generates control signals for the device, which acts solely along the locking axis to enable or disable the door locking assembly. The coded signals include two separate signals which are transmitted in segments interleaved with one another. The first signal includes an entrance code, while the second signal provides information concerning the frequency over which the next segments will be transmitted. The processor uses the second signal information to tune the receiver.

Remotely-operated self-contained electronic lock security system assembly

A locking mechanism for use in a door and the like. A remote handheld controller transmits coded signals to an electronic door lock. A sensor/receiver receives the signals and provides the signal to a processor which compares the coded signals against a predetermined stored signal. If the received coded signal matches the predetermined signal, then the processor generates control signals to actuate an electromechanical device, which acts solely along or about the locking axis, to enable or disable the locking latch. The user is then able to turn the door handle in a normal manner. The coded signals are comprised of two separate signals which are transmitted in segments interleaved with one another. The first signal includes an entrance code, while the second signal provides information concerning the frequency over which the next segments will be transmitted. The processor uses the second signal information to tune the receiver.

Remotely operated self-contained electronic lock security system assembly

A keyless locking mechanism for use in a door or the like. An operator activates the system by means of a portable remote handheld controller or a remote keypad unit, which transmit coded signals to an electronically controlled, electromechanical door lock device. The electronic and electromechanical device components are configured for secure mounting within the void or hollow portions of existing door locking apparatus, such as within the hollow interior doorknob, or hollow cylindrical sleeve latch actuators, or beneath the interior rose or escutcheon plates. A sensor or receiver/antenna mounted within the outer doorknob receives and forwards the coded signals to a processor which compares them with a predetermined stored signal. If an acceptable comparison is made, the processor generates control signals for the electromechanical device, which acts solely along or about the locking axis to enable or disable the door locking assembly, according to the command initiated by the operator. When locked, the outer doorknob turns freely. When unlocked, it operates in the normal manner, to engage and move the doorlatch and or locking member. Several embodiments of the electromechanical locking device are disclosed. The coded signals include two separate signals which are transmitted in segments interleaved with one another. The first signal includes an entrance code, while the second signal provides information concerning the frequency over which the next segments will be transmitted. The processor uses the second signal information to tune the receiver. Two-way communication between the handheld controller, or keypad and the electronic lock assembly is provided. A master programming unit for programming or reprogramming the electronic lock assembly is also disclosed.

The present invention provides for a locking mechanism for use in a door and the like. A remote handheld controller transmits coded signals to an electronic door lock. A sensor/receiver receives the signals and provides the signal to a processor which compares the coded signals against a predetermined stored signal. If the received coded signal matches the predetermined signal, then the processor generates control signals to actuate an electromechanical device, which acts solely along or about the locking axis, to enable or disable the locking latch. The user is then able to turn the door handle in a normal manner. The coded signals are comprised of two separate signals which are transmitted in segments interleaved with one another. The first signal includes an entrance code, while the second signal provides information concerning the frequency over which the next segments will be transmitted. The processor uses the second signal information to tune the receiver.
