Abstract: A remote control system including a mobile unit and a remote device. The mobile unit stores first data and has a first processor. The remote device stores second data and is wireless-connected to the mobile unit for receiving the first data. The remote device has a random number generator and a second processor. The random number generator provides a random number. The random number is sent to the mobile unit when the first data correspond to the second data. The second processor, coupled to the random number generator, generates a second code based on at least the random number. The first processor generates a first code based on at least the random number and sends the first code to the remote device. The remote device is activated when the first code corresponds to the second code.
