Abstract: A remote control for one or more electronic devices, including audio/video components such as a television receiver, DVD player, and VCR, includes a user interface such as a keypad having multiple keys, an emitter that emits signals corresponding to the keys, and a locking circuit coupled to the keypad for setting and resetting a locking switch. Upon setting the locking switch, in response to depressing the keys, the emitter is preempted from emitting signals corresponding to the keys. Upon resetting the locking switch, the emitter is capable of emitting signals corresponding to the keys.
