Universal Transmitter
WARNING: This page is about a different car, the 2005 Lincoln LS. However, it is still accessible from the selected car via links, so may be relevant.
The HomeLink(R) universal transmitter is an integral part of the left hand sun visor assembly. This universal transmitter provides a convenient way to substitute up to 3 hand-held transmitters with a single built-in device. The transmitter will learn the radio frequency codes of most current transmitters to operate garage doors, entry gates, security systems, and home or office lighting.
