    • Methods and apparatus are provided for a key-less system for actuating a lock responsive to a valid OPEN signal. A first portion is continuously coupled to a power source and a second portion receives power from the source only when a coupling switch is ON. The first portion comprises a keypad for entry of a lock actuation code, and a detector that senses the first keystroke and turns the switch ON. The second portion includes an RF transmitter and preferably a memory with valid actuation codes stored therein, and a processor coupled to the memory, to the keypad and to the RF transmitter. When the entered and stored keystrokes match, the RF transmitter sends an OPEN signal to the lock. The method comprises detecting the first keystroke, tuming on the power switch ON, comparing the entered and stored keystrokes and if matched, transmitting an OPEN command to the lock.
    • 提供方法和装置用于无钥匙系统,用于响应于有效的OPEN信号来致动锁。 第一部分连续地耦合到电源,并且第二部分仅在耦合开关接通时从源接收电力。 第一部分包括用于输入锁定致动代码的小键盘,以及感测第一击键并将开关打开的检测器。 第二部分包括RF发射器,并且优选地具有存储在其中的有效致动代码的存储器,以及耦合到存储器,处理器和RF发射器的处理器。 当输入和存储的按键匹配时,RF发射器向锁定器发送OPEN信号。 该方法包括检测第一击键,电源开关ON,比较输入和存储的按键,如果匹配,则将OPEN命令发送到锁。
