1. Remove the mechanical key from the SmartKey or push down on the mechanical (if you have the original SmartKey from the vehicle)
2. Insert that mechanical key into the lock where you press to open the trunk.
3. Trunk is open.
Thanks for the reply but they are going to charge. I just need to figure out a way to get power to the battery. Can I do it though the Alternator or any othe scources from underneath the hood or maybe some how open the back seats.
Don't you have battery post access tabs on that car?
Look on the passenger side under the door, see if you have a square tab there. That should be your + side. Double check, though. I've never had to use mine, and mine is a 215, so it may be different than yours.
mercedes roadside assistance is free no matter the age of your car
If you dont want to use them, all you need to do is get a "portable jumpstart" machine that plugs into the cigarette lighter, they dont do a good job to charge the battery enough to start the car, but should give the car enough power to pop the trunk.....
most auto parts stores and large dept stores sell them
or the have lighter to lighter jump starters..again not really powerful enough to start the car, but will give enough juice to pop the trunk
These cars do not like jump starts, there are chargers through the cigarette lighter, etc. but I do not recommend them, you will most likely fry the Electronic Gateway Module which will cost you 10X of what MB Roadside might charge to open your trunk.
I recommend you call MB Roadside and ask if there is a charge and how much.
All the same aestafford, when you introduce an external source into the electrical system you risk a power surge damaging electronics in these cars. Did you try Sathina's suggestion? I recall my 2000 S500 had battery posts in the trunk which are used for jump starting, so his suggestion might be a good one for you.
Since everyone is touchy on this subject, DO AT YOUR OWN RISK!
I had the battery crap out on me a few times, and the trunk would not open with the blade either, and I jumped my 02 S500 numerous times without any electronic damage, but the 02's dont have the Electronic Gateway Module. What you can do is fold down the floor carpeting on the front passenger side, remove the metal shield thats held in place by 3 10mm plastic nuts, and you will see and exposed positive terminal, one where the red battery cable connects to. Connect the positive end of the jumper to it, and connect the negative to any exposed stud or any other bare metal on the frame. There you go. Works for me every time.

If you are out of warranty MB Roadside will charge you. Wouldn't you rather pay a few bucks to have this done correctly, rather that play games with your $100K+ car?
I have had to call MB Roadside for my SL55 on a couple of occasions, and it was worth the money, and they took great care of the car. btw, the pricing was more than fair.

They do not charge for jumpstarts or battery installation , regardless of warranty or manufacture date.
If you need a new battery, they just charge the price of the battery with no install service charge, at least here in CA thats their policy
He needs to get the trunk open first which MB Roadside will charge a nominal fee, jump starting will be free. This is when you wish you had a pass through from the rear seats to the trunk, ha!
Wouldnt they just use the jumpstart point mentioned below:

Ive never seen this power point, maybe someone can take a picture of it so we all know where it is?
Just open the hood. On the right side of the engine compartment along the firewall area there is a covered box which you can remove the cover to access the power distribution box.
If you have a jump battery you can hook up the positive of the battery to the lug of the biggest red wire in the the distribution box and the negative of the battery to the ground of the vehicle.
This will not give you enough power to jump start the vehicle but it will be enough to open the trunk, windows, etc.
Upon opening the trunk, you have access to the battery to jump or start.
If you need pictures, I can provide.

I had a similar situation but the battery not dead I opened my trunk tried to replace the latch. I take the latch out but didn't find a new one when I reassemble it, I did it quickly and didn't do everything specially this one.
I want to remind you that I have a leak in the latch so neither the button in driver side would work nor the remote and now I lost my chance in using the key and the trunk is closed / locked.
