Does anyone know if the 4th gen "key/fob" uses batteries? And if so, how does it come apart to get to the battery?

I'm having trouble with one remote key/fob. The wifes works fine, but she rarely uses it, mine is used several times a day and now it's intermitten if will or will not lock-unlock the doors.

I figured I'd start with the cheapest/easiest solution and do the battery if it has one before heading to the echanted land of the Dealer.

Thanks

Pull the real key out and it just pops open. You will see the seam where it is put together.

I bought the batteries at Wal-Mart - two for $3.97.

The battery is the CR2032. Just pop the key fob apart, replace the battery and snap it back together. No re-programming required or anything.

Yep - that's what it was.

Just like Jerry and buckmann said, pulled the emergency key and pryed open the two halfs of the fob.

Ran to WalMart and sure enough the CR2032 fit like it was meant to be (Thanks TRX).

I did pull the circuit board out of the rubber pocket and cleaned the contacts on the back of the board (small copper rings that look like targets).

Again, thanks all.

doesn't hurt to rough up the battery on the negative side either. that seems to have helped a lot of people on here to get better results with fob operation.

X2 on the burnishing of the battery contact sides, also check for lint on the fob contacts.

A pencil eraser works good for cleaning the contacts.
