trunk lock to my 300d id broken how can I open the trunk

 

the lock is only actuated by vacuum element.

apply air pressure instead of vacuum to the line and it will unlock.

your next question will be: where is the vacuum line located?

 

thst will work even though lock was broken with hammer. someone try to brake in the trunk by hitting the lock botton in. when i open my front door i here the trunk unlocking but wont open

 

i see.... he used the wrong hammer. what's inside the trunk that gives him interest anyway?

if you can hear the trunk locking "unlocking", then it's just a mechanical problem now.

you need to change that lock anyway, so why not get a good drill and start removing it.

the only problem that i can see now is that you are going to bring two keys all the time if you will not order a set of key and lock for the whole car (ignition switch, doors, glove box, and trunk).

if you want to try thr pneumatic...here's the diagram.
