First Claim
Patent Images
1. A method of preparing an identification device for communication with a keyless entry system comprising the steps of:
- a) determining which of at least two communication protocols are desired for communication with the keyless entry system; and
b) manipulating physical features of the identification device in a defined order to select the determined one of the at least two communication protocols.

Abstract
An identification device is user configurable to communicate according to different communication protocols. Once the identification device has been set to a desired communication protocol where all it will immediately transmit an identification code to the corresponding vehicle controller such that the vehicle controller will learn the identification code and be able to recognize subsequent transmissions and authenticate the identification device.
