    It worked! Saved me $130! Thank you! I have a 2005 C230 and I used method 4 and it worked although the directions were not completely correct because there is no door unlock button on drivers door, there is only a lock and unlock button in the center of the dashboard above the audio system. So the instructions should go as follows:

    Open the hood find the battery remove negative cable for 2 minuets or 8 minuets depends on the car model. Put cable back. Push unlock button on the dashboard above the audio/radio box first, then push the trunk unlock button on the driver’s side door and then go to the trunk and grab the lever handle to open trunk lid and the trunk should open.
    THANKS AGAIN! YOU ARE AWESOME!

    We changed the batteries on the keyless fob for my 2004 C230. Now I can’t open the doors or the trunk. The Valet Key is missing. Ideas, anyone?

    2006 E350… had 6 locksmiths, two mechanics and two AAA drivers could not figure it out. Was contemplating cutting into the trunk until we found this post. Thank you so much.

    Method 9.

    This method assumes you have access to the cabin of the vehicle, sometimes you get lucky!

    1998 E300 Turbo Diesel (W210 test vehicle). Battery compartment under rear passenger seat. Once seat is removed, locate the air line from the PSE pump next to the battery. Apply 43psi (3bar). The trunk will open without power (battery dead and keys in the trunk). The website URL linked in this comment shows the youtube video I watched of a person demonstrating on a 2000 E430. Simply brilliant!
