I have a Mercedes C 230 that the trunk can not be opened with the key or the button. It just stopped being able to open. I thought there should be a way to open it without paying $ 100.00 to a dealer. 2 Answers

The trunk worked fine and I have tried everything I have heard or in the manual. Thank you for any suggestions.
