KEY FOB DONGLE

摘要

The disclosed method uses a dongle to program a replacement key fob transmitter to a vehicle. The dongle mates to the vehicle's on-board electronics through the vehicle's existing data link. A diagnostic circuit in the dongle determines a communications protocol for programming the key fob transmitter to the vehicle. Audio and visual indicators indicate that communications are established and the successful programming of the key fob transmitter to the vehicle.
