Abstract
A dual purpose key fob has manipulable keys for, in a normal mode, locking and unlocking a vehicle and keys for opening a vehicle trunk and activating a panic alarm and, in a training mode, for sending code signals to tire pressure sensors to tell the sensors what tire they are in, e.g., after wheel rotation, so that the sensors subsequently can transmit the proper location signals to the vehicle's ECM along with the pressure signals.
