Keyless entry system for automotive vehicle devices with theft-prevention feature

A keyless entry system for an automotive vehicle for operating one of a plurality of vehicle devices including a door lock device which is selectively operated to either of a first position which is a locked position or a second position which is an unlocked position, comprising:

• a plurality of electrical actuators respectively associated with the corresponding vehicle devices and responsive to a control signal to operate said corresponding vehicle device to a desired position, which includes a door lock actuator for operating said door lock device between said first locked position and said second unlocked position;
• a plurality of manual switches, each operating one of the corresponding vehicle devices;
• a transmitter outputting a radio signal indicative of a unique code which identifies the transmitter when one of said manual switches is manually operated;
• controller means for receiving said radio signal from said transmitter, comparing the unique code indicated by said radio signal with a preset code, and producing said control signal when said unique code matches said preset code, said controller means including means responsive to manual operation of one of said manual switches for identifying a corresponding one of said actuators to be operated and operating said identified actuator for operating one of the vehicle devices corresponding to the one manual switch operated;
• and
• a disabling means for detecting a predetermined disabling condition and for disabling said controller means when said predetermined disabling condition is detected, said predetermined disabling condition comprising a predetermined position of a key within a keyslot such that said disabling means disables said controller when said key assumes said predetermined position within said keyslot.

A keyless entry system for an automotive vehicle lock device for selectably actuating the lock device to either of a first position which is a locked position or a second position which is an unlocked position, comprising:

• an electrical actuator associated with the corresponding lock device and responsive to a control signal to reverse the position of said lock device;
• a manual switch;
• a transmitter outputting, in response to a demand signal, a radio signal indicative of a unique code which identifies the transmitter;
• controller means responsive to manual operation of said manual switch for transmitting said demand signal, for receiving said radio signal from said transmitter, for comparing the unique code indicated by said radio signal with a preset code, and for producing said control signal when said unique code matches said preset code so as to reverse the position of said lock device between said first position and said second position;
• and
• disabling means detecting a presence of an ignition key inserted in an ignition key cylinder of an ignition switch for disabling said controller means from producing said control signal so as to prevent said actuator from actuating said lock device to said first locked position when the presence of the ignition key in the ignition key cylinder is detected.

• a manual switch;
• a transmitter outputting, in response to a demand signal, a radio signal indicative of a unique code which identifies the transmitter;
• controller means responsive to manual operation of said manual switch, for transmitting said demand signal, for receiving said radio signal from said transmitter, for comparing the unique code indicated by said radio signal with a preset code, and for producing said control signal when said unique code matches said preset code so as to reverse the position of said lock device between said first position and said second position;
• and
• disabling means detecting an ignition switch positioned other than OFF for disabling said controller means from producing said control signal so as to prevent said actuator from operating said lock device to said first locked position when said ignition switch position other than OFF position is detected.
