A couple of days ago I went to get into the trunk of my 2006 slk280 and although there is sound the trunk does not release and open. The partition is in place so I can open and close the roof and access the trunk that way. Can I push the emergency release from the inside while the trunk is opened backwards without messing up anything? Anyone have experience with this? If I can open the trunk changing out the lock would not be a real problem.
