I had the same problem, the battery was dead. Unfortunately the key wouldn't open the trunk. This seems to be a common problem on this vehicle. If you have this problem, here is an easy solution that works great.
Open the hood and locate the fuse box on the drivers side.
Remove a larger fuse such as 30A and insert a small piece of wire and replace the fuse so contact is made.
Set a charger to a low amperage such as 10A.
Attach the positive connection of a charger to the wire and the negative to the frame of the car.
This will provide enough power to the system to use the trunk release.

2000 Mercedes are developing a fault.
An E43o is a vehicle of the Mercedes Benz E-Class. On a 2000 e430, the fuel pump relay is located directly under the seat, near the battery.
The battery on a 2000 E Class is located in the trunk. Mercedes puts the battery there so there is no chance of it being ruptured in an accident. The new E Class battery is however located under the hood just in front of the firewall. I think the above answer is wrong. The battery of the 2000 E class is under the rear seat cushion. Push up on the clips at each end of the rear seat cushion and unclip it, the battery is then found on the passenger side under the seat.
