How To Prolong the life of the Keyless Entry Door Handles
This is how I keep Mercedes Keyless Entry working and prevent from dying. Since I started doing this trick 4 years ago the keyless entry on my W211 E63 AMG and W211 E350 never died. Note: it won't fix already broken entry system, but it may help to prolong the life of the functioning keyless entry of your Mercedes.

It is so annoying. It helps me though. Haven’t replaced them in a while since doing this. But you have to remember to do it often as the rain will eventually wash it away.
