glad to see I am not alone. what happened to me is vacume lock stopped working, so my mech just unhooked the vac, connection. this ment I had to simply use my key each time I wanted to lock or unlock the trunk. then stoped working took to a different shop and they drilled a small hole under the licence plat and popped it with a tool(bent screwdriver I think) problem is they wouldn't let me back to see how he did it. has happened again (after at least another yr of service) and I try a little each day, but no success so far.as to me duplicating the forced entry job,I hate to drill it out at the lock itself as that gets expensive to replace. has anyone else had to break into there trunk? I tried locksmiths and they didn't want to try on a mercedes.
