Of course you can. The battery is located on the left side under the rear seat.
There are two latches you must unlock before you can slide the seat forward and lift it up.
Good luck!!!

disconnect the battery and reconnect. when the battery is reconnected within 20 secinds turn the ignition on and press the immobiliser button on the remote device ( the unlock button on the key ). that should reprogramme the receiver and the transmmitter.
It is located under the back seat.
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.

Best to unplug it and then disconnect it from the battery. Reason being is that if you disconnect it from the battery first you will create a spark. That spark could ignite any fumes from the battery.
I'm pretty sure you need a code reader which has a reset. Other wise, in some cases, I think you can disconnect the battery which resets the computer in some cars.
If working on the electrics of a car then it is a sensible precaution to disconnect the battery.
Yes, you better disconnect the negative battery cable.
