I have a 2010 Mercedes E350. I only have one key and I locked it by mistake in the trunk. AAA came and managed to get the car open but by breaking in, they neutralized the security system so the "pop the trunk key" within the car doesn't work. Does anyone know how I can get the trunk open?


Try reaching through the rear seat or the speaker. Use a long stick to press the trunk release button in the trunk.

The other option is to go to the deaer and order ONLY the metal blade key. It's not that much and you can use it to open the trunk.
