How to get into car when battery is flat?

I have a Mercedes B200. The battery has run down totally and the electric locks cannot be opened with the button on the key. I tried the manual key, but that wont open the door either. How do I get into the car to get to the battery to recharge it?

Hello i have an e- class electric key which maybe the same, if it is :- if you look at your key you will see a rough nobly curve near the silver edge of silver with a hole in it, push the rough bit up, and pull out a sketeton key.

Mercedes e220cdi 2003 battery is totally dead can't open doors or boot to change battery. have got key fob with infra red so no actual metal key to manually open door. help as i need to sell this car.

This is a very serious situation as there are only a few ways you can go about this.
The surest way out of this is to call a mechanic over and have him help you open the lock from outside.
He can do this by picking the lock or by working on the door panel.
There is no other secure method as the car would not come on neither will it open.
hope this helped you? Please comment for more information.

Sounds daft but I can't access the battery in the boot - because the electrics have run down and the electric door and boot locks are inoperable. The boot lock has a key symbol on it but no obvious...

you need to jack the car up and attempt to locate the starter and you can use a battery box to jump the system off the main wire on the starter needs to be boosted with another vehicle or a jumper box but that should charge the system enough to open the door hope that that gets you in there it worked on my 740IL BMW

B200, 2006 cvt trany,starter doe,s not crank at all every once in a while, battery ok, connections et ground ok. the scanner tell,s us starter is defect. I dont have a wiring diagram so i have to figure...

You can electrical supply directly from plus battery to electrical starter solenoid.
For that you must prepar an electrical wire. One end connected at the electrical starter solenoid, and another end directly on plus battery. If electrical starter crancks the problem is on electrical supply. If doesn't cranks then electrical starter
is out of order and must be removed from engine and repaired! The most frequent problem of electric starters are carbon brushes used!
Did you try this operation?
