(1) Turn the engine on with the key FOB you want to program.
(2) Move the seat and mirrors to the desired position
(3) Press the "M" button and hold it down
(4) While holding the "M" button down, press the "key" button, then release the "key" button without releasing the "M" button
(5) While still holding the "M" button down, press the "1" button to program it to "1"
(6) Release both the "1" button and the "M" button at the same time

That's it. If you want to program your key to the "2" position, just repeat the procedure and push the "2" button instead of the "1" button.
