Key Fob unlocks only when the key if right over driver side door. Doesn't work from a distance at all. What can I do to fix this? Key has brand new battery.

 

Still need help anybody have any advice?

 

Try the e55 forum. Same car, different body style. Most of us cls guys hang over there anyway.

 

I know the battery is new, but have you tried another new battery... I can't think what else the problem could be... I bought new batteries for remotes and both sets turned out to be old flat... Only my third set did the unit stop telling me that battery was flat..

 

I've replaced the battery 3 separate times red light shows on key from anywhere but nothing happens to car unless I'm right under the driver side door.
