Hello everyone. I'm new here but having a problem with my ML350, or more specifically, my key fob. I've now replaced the battery in both of my key fobs 4 times in the past two months. I've used both energizer and duracells. The car will usually recognize that the battery is new, but within just a few days, it starts telling me the battery is low and needs to be replaced. It's doing this with BOTH key fobs. At first I just thought I got a bad battery, or two, but there's no way I've bought 4 bad batteries in a row. Then I thought maybe the fob was bad and a button was stuck or something, so it was draining the battery quickly. But, it's doing it with BOTH fobs. So that's probably not it. So maybe it's something with the software?

Any suggestions? Thanks in advance for your help.
