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.

Then you call MB Roadside Assistance to have them come to you and open your trunk. I am not even going to ask why your keys were left in your trunk.

Good luck!

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.

jumpstarts are free through MB roadside assist, that I know.

I dont know if "lockouts" are free too. Just tell them you have a dead battery, they will come out for free and take care of you.

If you need a new battery they will also change it with no markup and just the price of the part, no installation labor

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

FOr other roadside services, yes they may charge.

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!

Easy!

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.

THere are Terminals in the engine compartment. And yes they are safe to use otherwise they would not have been installed there by the factory.

If all you need is power to open your trunk, connecting a 12v power source to this terminal will do the trick then use the trunk open switch.

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.

I will tell you what i did step by stem after spending a long time searching solutions here and there.
1- I removed the license plate



2- Under the plate, there is a screw that can't be removed from the outside the trunk



simply because it looks like this



so I have to use the drill to release it. my idea was to make a hole in it and make it lose its flat head.























3- I was surprised that it got loose and went out but its hole became a little wider but it is still good for it when I want to use it again.




4- Now I reached the lock and it has 2 screws




5- I loosed them and the action started

6- to my surprise the lock doesn't fall inside the trunk. it only moves an inch to the left or the right. but fortunately I could see my target.




OK all I have to do is to catch it with a (pincer, pliers) and pull it up



but every time I try to catch it, it moves to the inside so ....

7- I have to use a hook to make it stay in place










8- I inserted the pliers with the rod and catch it and pull it up. and it opened

9- from the inside it looked like this



10- Now I knew why the lock doesn't fall inside. there is a screw that hold it in place inside the trunk




I HOPE this post be helpful to you.
