Can't lock the trunk.
 

Something went wrong when trying to open the trunk I turned the key to far left position and heard a strange click. After that strange click I can't turn the key back to right and the lock is stuck at the far left "open" postition. I tried removing the 3 bolts and tried removing the lock but couldn't remove the metal line for vacuume connection .
Is it easy to disassemble and reassemble the lock?
What could have gone wrong with it?
