It is, according to this:My key is completely dead. I've tried recharging it on a 3 hr trip but nothing. Is it possible to take it apart and replace the battery?
Haha no laundering...2nd key works fine. I guess the battery is dead. I'll try the process in that link. Thanks!It is, according to this:
But it sounds as though it isn't easy, nor a guarantee of success.
Have you ruled out the in-car receiver - 2nd. key still works O.K.?
No chance that the key got laundered accidentally?
Call a dealer and ask if they do a "key reset" procedure?
Maybe a connection with the burning smell during your high speed mountain driving recently?... Oddly enough, it will respond on rare occasion, as in once a day at some random time. That's the case for both keys. And then it stops working a few hours later.

Ahhh we did secure the wiring to another cable running along the interior which could have created some kind of RF interference. Good point.Do this first, cut open those plastic ties, and secure the wires again but tying them in a different way. Just open them up and try your keys if they work. Check for any short circuits etc. Just thinking that there is a loop with those wires acting like antenna. :dunno:

and allows for different situations (1 working key, etc.):
Don't know how reliable the source is.
It implies the receiver is located in the driver's "B" pillar.
Azn, if it is intermittently working it may just be that the battery is on its last leg. Are they the original batteries?No luck in undoing the bindings. I don't have much time this week but perhaps I can squeeze a trip to the dealer, where they will tell me that some $1000 part is broken and I need to replace it.
