Hi there
First of all may i say i feel your pain. literally. the same thing happened to mine. here is what i did
Firstly i needed into a locked boot urgently (for wifes wheelchair)
so i cut a rectangle out of the boot put my hand in and pulled the release mechanism, that worked but left me with a hole in my boot.
I suggest that you try this instead.
remove back seat
the central locking pump is located next to the battery (black box with yellow air lines going into it.)
Unplugg the filler cap cover air line, then unplugg the boot air line and put it into the filler cap cover socket.
now when you unlock the car the boot should automatically open.
If it does not the problem it on the boot air line and you should strip the trim out of the boot to check, but you still have to get in and may have to do what i did initially.
If changing the air line worked then you will soon get tired of having to shut the boot everytime i solved this problem by routing the filler cap air line to a pnuematic switch (LEGO) This switches between the boot and the filler cap. bit naff but it works and cheaper than having to replace pump and have computer and keys re-coded total cost around £600.
op that helps

SOURCE: How do I unlock the shifter on a 2000 Mercedes

No you do NOT need a new transmission.
This model Mercedes uses an electronic solenoid in the shift housing, to take the linkage out of park.
There is a small plastic part, activated by a solenoid that pushes a release, allowing the shifter to come out of park. Most of the parts in the box were metal. This particular part is plastic and very frail.
It is not an easy job, but any mechanic can do it.
