HELP! Trunk lock
Hey (sorry for english)
I own an E-Class w211 sedan, and my trunk is locked, and i have lost the physical key
I have checked all the wires for the trunk lock, and i have checked all fuses and relays. Can the whole SAM unit be broken?

You can just order the metal key from Mercedes instead of the entire key. It's a lot cheaper than the whole key fob.

Bet there's a broken wire somewhere in the left trunk hinge wiring harness. A known issue with many searchable threads on this forum.

Question though: if your trunk is locked, presumably closed, how did you check all the wires?
