Sorry about the trouble you're having.

My convertible top got out of sync two days ago and the trunk was locked. (I had just put my laptop computer in the trunk and it messed me up for a meeting when I couldn't get it out.) I've got a 2005.

I went in through the passenger side license plate light opening. With a long screwdriver, I was able to push on something that looks like a white bellows unit. As soon as the screwdriver deflected the bellows a little, the trunk was unlocked. Sometimes I get lucky when I don't know what I'm doing...but not very often.

Once it was unlocked, I followed Pizzaguy's instructions for resetting the convertible top computer by manually raising and lowering the top three times with the engine running. It's back to "normal" again.

Hang in there.
