Coding for non functional keys of a keyboard or keypad

A system comprising:

• a keyboard processor module configured to communicate an actuation of functional keys of a keyboard;
• a memory comprising non-functional key (NFK) codes;
• and
• a processor coupled to the memory and the keyboard processor module, the processor comprising an NFK coding mode processor configured to:
• in response to detecting an NFK coding initiation command, activate an NFK coding mode by sending a request to a server for downloading NFK codes and receiving the NFK codes sent by the server in response to the request, wherein the NFK coding initiation command is a coded sequence of functional keys and none of the functional keys are dedicated to activating the NFK coding mode, and the request is sent using a short message service (SMS);
• and
• during the NFK coding mode, indicate a function associated with a non-functional key to the processor based on the NFK codes and a successive actuation of at least two functional keys;
• and
• wherein NFK codes are downloaded onto the memory from a server through a network.
