An apparatus remotely controls, for example, door locking/unlocking and alarm activation of an automobile. A transmitting device transmits communication data, which includes synchronization data and identification data. The communication data is received by the control apparatus in which the identification data included in the received communication data is compared with already stored data. The locking and unlocking of the doors of the vehicle is carried out when the identification data matches the already stored data. A continuous reception condition is detected when the communication data is received for more than a predetermined period of time. When the continuous reception condition is detected, an alarm is actuated. As such, a common transmitting button of the transmitting device can be used to effect both control of the locking and unlocking of doors and alarm activation. The control apparatus may also include an erasable memory which is remotely settable in a writable status and in which identification data can be erased by remote control while in the writable status.

Receiving apparatus

The remote control security system includes a receiver which receives communication data, including identification data, from a transmitter. The system also includes a device for locking and unlocking doors when the received identification data match prestored identification data. The system also includes a device for determining whether the communication data is continuously received for more than a preset period of time and for generating an alarm when the continuous receiving condition is determined by a determining device.
