Abstract

A system and process is disclosed for duplicating or replicating remote control units for automobile locks and other common purposes. The system comprises a device that reads the remote control signal codes in an existing keyfob device, analyzes the code for type, stores the code, then transfers the code into a replacement remote control device. The process for testing, reading, analyzing, storing and transferring the control codes is also disclosed.

Claims

1. A process for duplicating the programming of a remote control device comprising the steps:

testing an existing remote control unit by activating a single control input on the unit;

receiving a signal from the existing remote control unit upon testing, said signal comprising a transmission frequency and a code having a type and content;

displaying a feedback message that confirms reception of said signal;

repeating the testing and receiving steps at least once more;

comparing the signals received from the remote control unit and determining the average frequency and the code type employed in the remote control unit;

storing the code content;

repeating the testing and storing for each control input on the remote control unit;

transferring the stored code into a replacement remote control unit.
