the trunk of my 2002 C230 opens only with metal key or emergency button. somehow, I'm not able to unlock the trunk from the remote, but I need to switch the key in and then press the latch. Any idea what the problem could be?

I wouldnt just go replacing the remote before you test it a lot of auto parts store like auto zone have remote testers on there parts counters.You test for a signal coming from the remote while you press each button.That would be a expensive guess.

I would think they would use a solenoid to release the trunk when the remote so theres another possibilty there so please check the remote to make sure its bad.
