Key fob woes

foofopps · 07-07-2012, 02:48 PM

So when I bought my car 2 weeks ago it only came with one key. I got a call yesterday from the dealer and a 2nd key for the car arrived with the manual. I was pretty excited I didn't have to buy another key. I tried to use the 2nd key I recieved and ran into a few problems. The comfort access was not working and none of the buttons were working. However when I put the key in the "ignition" the car started. So I put a new (correct) battery in the remote and tried again. Everything worked; buttons on fob and comfort access.

Now the problem lies with my 1st key. I put the 2nd key back into my house for a spare and went back to using the original key which I never had an issue with. Now this key is having the same exact symptoms of the 2nd key initially had. This key will start the car in the "ignition" but no other functions of comfort access or fob buttons work.

I've been reading the manual and have not seen anything that explains switching keys and if there are any steps to activate a key. I have started and stoped the engine several times with my key and it has not returned to normal operation.

Is there something I'm missing here? Is there something I am suppose to do when switching back and forth between my two keys??

try getting a new battery for it and see if that fixes it.

I had a similar problem, turns out the original owner lost one of the fobs and when I purchased the vehicle they used one from a 5 series. The service department was able to reprogram the problematic fob easily.

I put in a new battery and all the comfort access features now work but the buttons on the remote still do not. I'll look into getting it reprogrammed.
