How do I program a new RKE transmitter to my 2012 Cadillac SRX if I have an existing recognized transmitter?

Place the recognized transmitter(s) in the cupholder, then insert the new transmitter's key into the driver door lock cylinder and turn it to the unlock position five times within ten seconds until the DIC displays 'Ready To Learn Electronic Key.' Place the new transmitter in the transmitter pocket inside the center console, press the ignition, and when learned, press the K button on the new transmitter. When all transmitters are programmed, press and hold the ignition for 10 seconds to exit programming mode. (Page 38)
