my rant on keyless go
1. I keep losing my keys when i use it loll
2. i rarely use the key anymore so it stopped charging the remote and i had to manually open the doors

If you're talking about the key, I don't believe it gets charged. It has a lithium round disk shaped battery that you need to replace if it goes dead.
I think it's the BMW keys that get charged when in the ignition. There are no metal contacts on the mercedes smartkey.

So I wouldn't worry about it too much and the battery is really easy to replace.
