Was certainly thinking it was rechargeable as I have been told that it was. According to the owners manual:
"Each remote control contains a rechargeable battery that is automatically recharged when it is in the ignition lock while the car is being driven. Use each remote control at least twice a year for longer road trips in order to maintain the batteries' charge staus. In cars with convenient access* the remote control contains a replaceable battery, replace battery + side up...

all that said, I was told the battery in my FOB was rechargeable. I was getting the low battery indicator and put the FOB in the ignition lock and the low battery warning indicator hasn't come back.....
