Abstract: In a steering lock device of a type which can unlock a steering shaft of a vehicle without using a key, there is provided a so-called "back-up" means for assuring the steering shaft unlocking condition of the device when the key in a key rotor assumes "ignition ON" position. The means comprises a pivotally supported check lever having a first end projectable into the key rotor and a second end lockably engageable with a steering shaft locking bar. When the keyless unlocking is intended, the first end of the check lever is moved away from the key rotor by an electromagnetically actuated plunger thereby permitting rotation of the rotor toward the ON position disengaging the locking bar from the steering shaft. Upon completion of disengagement of the locking bar from the steering shaft, the second end of the check lever is brought into locking engagement with the locking bar thereby holding the same in the steering shaft unlocking condition.

The controller has a preset code to compare with the unique code indicative in the radio signal transmitted from the transmitter. The controller also detects impending or accomplished locking of the transmitter in the vehicle and produces an alarm and subsequently disables the keyless entry system unless the transmitter is removed from the vehicle within a given period of time after the alarm is given.

Abstract: A theft preventive system, in an automotive keyless entry system with automatic door locking, is adapted to produce an alarm signal in response to door opening when the theft preventive system is in a door-locked position, and which is cooperative with a door-lock system but independently operable in order to switch its operating mode from a door-locked mode to a door-unlocked mode. The theft preventive system in an automotive keyless entry system, according to the present invention, includes a push-button-type function key for operating a door-lock mechanism to lock a vehicle door. A memory circuit is responsive to a door-lock signal fed from the door-lock function key to indicate the door-locked condition. The content of the memory cannot be cleared unless a plurality of door-unlock function keys are properly operated. An alarm circuit is responsive to a door-open signal from a door switch in the presence of a memory output indicative of the door-locked condition to produce an alarm signal.
