Keyless entry module and method
First Claim
1. A key-less system for actuating a lock responsive to a valid OPEN command, comprising:
- a power source;
a first system portion coupled to the power source and receiving power therefrom while the system is in an active or inactive state, wherein the first system portion comprising;
a keypad having at least one key that when depressed provides an electronic signal representing an entered actuation code; and
a detector coupled to the keypad that intercepts at least a first keystroke of the at least one key and in response to the first keystroke turns the switch ON, thereby making the second system portion active; and
a second system portion coupled to the power source by a switch and receiving power therefrom and in an active state only when the switch is ON, wherein the second system portion comprising;
a memory with one or more valid actuation codes stored therein;
a processor coupled to the memory and the keypad, wherein the processor receives from the keypad, keystroke sequences representing an entered actuation code and compares them to valid actuation codes retrieved from the memory to detect a match; and
a transmitter coupled to the processor, wherein when the processor detects the match, the transmitter sends out an RF signal carrying the valid OPEN command recognizable by the lock.

Abstract
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, turning on the power switch ON, comparing the entered and stored keystrokes and if matched, transmitting an OPEN command to the lock.

11. A method for key-less entry using a keypad, a keystroke detector, a processor, a memory and a power switch coupled to at least a transmitter, for remotely actuating a lock responsive to an “
- OPEN”
command, the method comprising;
detecting at least a first keystroke;
turning the power switch ON in response to detecting the at least first keystroke thereby powering-up at least the transmitter;
receiving multiple keystrokes from the keypad;
comparing the received keystrokes to one or more valid entry codes stored in the memory to identify a match; and
transmitting an RF signal containing the OPEN command to the lock if the match is identified. - View Dependent Claims (12, 13, 14, 15, 16, 17)

18. A key-less entry system for generating a valid command recognizable by a receiving apparatus, comprising:
-
a power source;
a switch coupled to the power source;
a first system portion coupled to the power source and receiving power therefrom while the system is in an active or inactive state, wherein the first system portion comprises;
a keypad having at least one key that when depressed provides an electronic signal representing an entered actuation code; and
a detector coupled to the keypad that intercepts at least a first keystroke of the at least one key and in response to the first keystroke turns the switch ON, thereby making the second system portion active;
a second system portion coupled to the switch and receiving power therefrom and in an active state only when the switch is ON, wherein the second portion comprises a transmitter wherein either the first or second portion comprises;
a memory with one or more valid actuation codes stored therein;
a processor coupled to the memory, the keypad and the transmitter, wherein the processor receives from the keypad, keystroke sequences representing an entered actuation code and compares them to valid actuation codes retrieved from the memory to detect a match; and
wherein when the processor detects the match, the transmitter sends out an RF signal carrying the valid command recognizable by the receiving apparatus. - View Dependent Claims (19, 20)
