摘要： A motor-vehicle lock system has a remote operator separate from the motor vehicle and having a key part having a predetermined bitting, a transmitter actuatable to transmit a main signal containing a main code word, and a transponder independent of the transmitter for receiving an interrogation signal and thereupon generating a callback signal containing a callback code word. A lock provided with a switch is actuatable mechanically by the key part to operate the switch. A receiver in the motor vehicle connected to a central lock controller receives the main signal including the main code word, extracts the main code word from the transmitted main signal, compares the extracted main code word with a predetermined main code word, and sends a release signal to the controller when the extracted main code word corresponds to the predetermined main code word to actuate the elements. A transceiver in the motor vehicle at the one lock is connected to the controller for, when the switch is actuated, generating the interrogation signal, receiving the callback signal containing the callback code word, extracting the callback code word from the callback signal, comparing the extracted callback code word with a predetermined callback code word, and sending a release signal to the controller when the extracted callback code word corresponds to the predetermined callback code word to actuate the elements.

摘要翻译： 机动车辆锁定系统具有与机动车辆分离的远程操作员，并具有具有预定接合的关键部分，可致动以发送包含主代码字的主信号的发射器和独立于发射机的应答器，用于接收询问 信号，从而生成包含回调码字的回叫信号。 设置有开关的锁可通过关键部件机械地致动以操作开关。 连接到中央锁定控制器的机动车辆中的接收器接收包括主码字的主信号，从发送的主信号中提取主码字，将提取的主码字与预定的主码字进行比较，并发送释放 当提取的主代码字对应于预定的主代码字以致动元件时，向控制器发信号。 在一个锁上的机动车辆中的收发器连接到控制器，当开关被致动时，产生询问信号，接收包含回叫码字的回叫信号，从回叫信号中提取回叫码字，比较 提取的回调码字与预定的回叫码字，并且当提取的回叫码字对应于预定的回调码字以致动元件时，向控制器发送释放信号。
