Step by step instructions for do-it-yourself repairs
2003 e500 dead battery and key wont open trunk HELP
Sounds like with the key turned press down on the lid to remove pressure it might open.
The other item is to go under the engine find a main power lead from the starter and jump power on the input to the solenoid starter to get power to open the trunk. (don't even think about jumping to turn the engine over just enough power for the trunk to open)
