I have a 2015 GT Premium. Love the car, but the fobs (both) eat batteries.
The original batteries lasted almost 2 years, but the replacement batteries only last 5 days. This is the case with both fobs. All suggestions are appreciated.
Did you install the two CR2025 batteries correctly? Once batteries are out, install the first battery with the {+} positive mark facing you. Then slide the plastic label back and install the second battery with the {-} negative facing you.
Both battery {+} positive marks should be facing each other with the plastic label between them.

Yep, I was very careful to install the batteries per the instructions.
I had the same issue with my 2000 key fob. I went to walmart.com and ordered two replacement fobs for only $8! I then installed a new battery in the original fob and following the instructions in the "key fob programming" guide in this sites "how to section" I programmed the new key fobs and haven't had an issue since. Try that because it worked for me
The fob for the S550 is a LOT different from the 2000. The fob is the car "key" so not as simple as buying a WalMart replacement and reprogramming it. The car recognizes the fob as you walk up so you just touch the handle to unlock the car and push a button to start.

There is still a physical key inside the S550 fobs, in case the battery dies.
Not sure what the problem is, why they are killing batteries. But if he had incorrectly installed the batteries (reverse polarity etc) then they wouldn't work at all.
I can see getting a bum package of batteries, one time. But multiple times it sounds like an issue with the fob. I have no idea how the newer fobs work but if they are constantly transmitting or something then that would definitely present a current drain worthy of explaining the problem.
