Abstract

A universal keyless entry transmitter for sending signals to multiple keyless entry systems. It includes a means for selecting any of several controlled devices and a means for entering transmission codes for each of those devices. In this embodiment, the transmitter is a key chain fob with buttons (26) for all the standard commands typically found on keyless entry systems, especially vehicle security systems. The device has a switch (22) for selecting which device is to be controlled, a fingerprint reader (32) for user identification and a programmable microprocessor (49) for storing user information and signal information for controlling devices. It contains an output display (24), and a menu system for programming signal information and user authorizations.

Claims

1. A programmable keyless entry transmitter for use with multiple vehicles or other devices equipped with keyless entry receivers;

the transmitter consisting of;

a programmable memory for storing signal format information for controlled devices;

a means to select a particular receiver device to be controlled;

a means of selecting a particular command to be transmitted; and

a transmitting antenna for sending commands to keyless entry receivers.

2. The transmitter of claim 1 further including means to program said transmitter with frequency and signal information specific to multiple keyless entry systems

3. The transmitter of claim 1 further including a means to authenticate users to prevent unauthorized use or access of the transmitter

4. The transmitter of claim 1 further including a means to limit authorized use of the transmitter to a range of pre-selected actions
