Techniques for pairing a remote control to a device are disclosed. After a specific button is pressed or buttons are pressed in a specific order, a remote control is caused to enter a re-programming mode. In the mode, the transmitting power of the remote control is significantly reduced, resulting in a much smaller working range. In addition, an identifier in the remote control is changed so that all subsequent command signals from the remote carry a different identifier. For the device to respond to the change in the remote control, a user has to bring the remote control up close to the device for receiving a command signal carrying the changed identifier from the remote control. Once the remote control is back to a normal mode, the remote control is paired with the device within its own working range.
