If you can open the hood, there is a battery pos(+) jump post in or near fuse box. Hook up a jumper box or jumper cables to power up the vehicle systems.

Just had the same problem.

The fact the key had not been used in many years the locking mechanism was basically stiff'

Applied copious amounts of wd40 kept turning the key back and forward while applying pressure and release to the boot lid did the trick

Posotive can be found in hood driver side next to fuse box. It is a small rectangle box. You can hook negative to any solid ground on the car.

I have the same issue (battery is completely dead in my 1998 Mercedes C280 and I can't pop open the trunk). I looked under the hood and have no idea where the positive charging post would be - can anyone help me find it? Thanks

How do i open Mercedes-Benz 1998 E320 trunk from the fuse box under the hood
You may be able to unlock the trunk from the door lock pump under the back seat. Remove the rear seat bottom and the insulation from the right side. You'll see the battery and a foam box. The door lock pump (PSE) is in the foam box. You need to remove the vacuum line for the trunk latch (labeled RTR or RHR on the PSE pump) and apply some air pressure to it to unlock the trunk. You should then be able to open the trunk normally, unless the trunk lock key tumbler is in the lock position, then you need a key to get in.

Try using a battery jump box with a cigarette lighter adapter, plug it in to the cig. lighter, you might be able to get power to some of the fuse box to use door lock switches or trunk release button .

Dead battery in locked trunk (Mercedes 1990)
Many People don't know exactly how to use the manual key attached to your remote to open the doors and trunk in case the battery is dead. All you have to do is slide the locking button in the back of your remote and pull the metal pre-cut key, then insert it in the trunk lock, turn key to the left and then push in. kawaboongha!!!

Yes but you must remove the rear seat back and cushion to crawl through or power up the system from under the hood at the jumper cable hook ups.
