A method and apparatus selectively controls operations of an original device and a non-original device in a vehicle through control keys mounted on a steering wheel. The method includes the steps of: interpreting a command code from the control key when the control key is activated to determine which function is selected; selecting one or more original or non-original devices to substantiate the selected function of the control key; retrieving data related to a command code of the selected function of the non-original device; converting the command code from the control key to a command code of the selected function of the non-original device and storing the converted command code; and retrieving and transmitting the converted command code and transmitting to the non-original device when the control key is activated again.
