There should be a positive charging post under the hood. Hook up jumper cables to this post for positive and the engine for ground. Then get in the car and pop the trunk with the trunk release button.

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

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.

is check engine light on or visit workshop displayed on cluster while engine is running. If so there is a electrical malfunction-although if the linkage is disconnected from the trans to the throttle the gear recognition switch would send an implausible signal and set a code. this code is not a priority code and may not set the light right away. A lot of times one of the linkage rod retaining clips falls off. Look under the car and you will see a rod that attaches to the shifter box arm and to the transmission neutral safety switch(manual valve) arm. It may actually be resting on the ground. If not look and make sure it is secure. Next there is a slot on the shifter wood where you can put a flat blade screw driver in and release the manual shifter lock. Your owners manual will describe how to do this. Depending on what failed the vehicle may be in what is called limo home mode where the trans does not shift out of second gear and the throttle is not very responsive. It will give you the opportunity to move the car to a safe location possibly even a repair shop. The shifter boxes are are a sealed unit with no replaceable parts. They are slightly expensive and require an s.d.s. machine to replace because they must be programmed and version coded. I hope I have been helpful
