Abstract
A vehicle wireless transmitter system includes a portable fob and a repeater mounted in the vehicle headliner. The portable fob includes user actuated buttons and code generation circuitry for a remote keyless entry system, garage door opener system, and home security system. When the user activates the garage door opener button on the portable fob from within the vehicle, the code generated by the portable fob is repeated by the repeater mounted in the vehicle headliner and retransmitted in a more powerful signal directed through the windshield. Thus, the portable fob insures that the code generation circuitry is removed from the vehicle with the user, while the repeater insures that the transmitted signal has enough power to provide satisfactory range.
