I need help this methods not working Or I’m not doing it right

 

I just did this on my 12 and it worked the first try. From the OP

(a) Open the driver side door and insert the key into the ignition cylinder.
(b) Remove the key from the ignition cylinder and, within 5 seconds, reinsert the key and turn the ignition switch to ON.
(c) After 10 seconds, the system enters answer-back buzzer switching mode.
(d) Within 10 seconds after answer-back buzzer switching mode is started, if a transmitter button (the same button) is pressed twice, the answer-back buzzer setting changes (off to on, or on to off) to activate or disable answer-back by buzzer.
