Having only a single key is a recipe for disaster, so I promptly ordered PN 94543206 (my original key is 94543205...) and had it cut at a locksmith yesterday.
Anyhow, the manual for 2016 doesn't seem to exist, nor did I receive one with the car, so I looked up the manual for the 2015 and there were procedures within. They do not seem to work.
What I did:
0. car not plugged in to power
1. approached car
2. unlock using remote
3. open flap on emergency key cover (ignition area)
4. insert existing key into ignition keyway
5. nearly immediately insert new key into driver side door keyway
6. turn door key from middle position to unlock position (counter-clockwise) 5 times at moderate speed (not trying to whip it from neutral to unlock quickly, though I did try at varying speeds) -- sometimes I tried more than 5 times, sometimes I tried faster, and sometimes slower
7. wait for anything to show up on the DIC, only usual driver entry information is shown (charge status, plug in to charge, mi remaining, etc.)
8. DIC goes blank after a while (idle timeout), and I try to repeat this all again several times, to the same effect.
The DIC never says "READY FOR REMOTE" etc.
I cannot proceed beyond step 2 below.I thought the 2016 was practically a newer 2015... Has the procedure really changed, or did I do something wrong?
Verbatim from the 2015 manual:
Programming with a Recognized Transmitter
A new transmitter can be programmed to the vehicle when there is one recognized transmitter. To program, the vehicle must be off and all of the transmitters, both currently recognized and new, must be with you.
1. Remove the rubber cap on the steering column. Press the button on the recognized transmitter to extend the key blade. Insert the key blade into the transmitter slot.
2. Insert the vehicle key of the new transmitter into the lock cylinder on the outside of the driver door and turn the key to the unlock position five times within 10 seconds.
The Driver Information Center (DIC) displays READY FOR REMOTE #2, 3, 4 or 5.
3. Remove the recognized key and place the new transmitter into the transmitter slot.
4. Press the POWER button. When the transmitter is learned, the DIC will show that it is ready to program the next transmitter.
5. Remove the transmitter from the transmitter and press X (UNLOCK button)
To program additional transmitters, repeat Steps 3-5
When all additional transmitters are programmed, press and hold the POWER for 12 seconds to exit programming mode.
Replace the plastic trim piece from the small storage area.
