An automatic dispensing device for use in storing and selectively dispensing electronic transmission devices, for example tire pressure monitoring system (TPMS) tire sensors. The dispensing device assists a user in determining the proper transmission device to be dispensed and programs or configures the transmission device in the dispenser prior to dispensing the programmed or configured transmission device to the user. When used for TPMS tire sensors, the dispenser determines the type of TPMS sensor to be programmed, programs the sensor with the proper communication protocol, and dispenses the programmed or configured sensor to the user for installation in the vehicle wheel and tire.
