I wonder if someone can help. My 2005 Vito has been stationary for a few months, the battery is flat and I'm unable to open the driver side door with the emergency key blade. I found a number of forum posts regarding the above scenario for other MB's, including tips and tricks on how to open the door with the emergency key, however so far I haven't had much luck. The key fob itself - which has a working battery - doesn't unlock the vehicle unfortunately since the car's battery is flat. Hence why I tried the emergency key instead. I tried to turn the key 90 degrees in the lock and then pull the door handle, as suggested in a relevant forum post, however that didn't make any difference. WD40 made no difference either. Any suggestion to resolve the above would be much appreciated. Thank you!
