I programmed this key and select smart key option, the key programming is successful using CGDI BMW key programmer and I was able to start the car and open/close using the frequency remote, but the keyless entry is not working, meaning you can open/close the door while the key is in your pocket. I compared the board of this key with the original car key and they are identical. I would give a five stars if the key work seamlessly including the keyless.
Edit: Now I would give a five stars for this product. BMW with Comfort Access or keyless entry for CAS3 allows only 2 assignment FOB. So I have to disable other lost keyless to make the new key to work CA.
