Want this question answered?
The battery in the keyless remote of a 1999 Mercedes E320 is changed by prying off the back cover and lifting the battery out. The battery will typically last 2 years or more under normal use.
Having the same problem, i believe it to be at the back left side under the bonnet. (Apparently there are 2 fuse boxed there and 1 under the back seat.)
The battery is in the trunk, far right side under a removable panel.
