Does it ever open with the switch or only with the key?
Mine hadn't worked with the switch since I bought the car, but it made noise like it should. One day, years later, I had the cover off the trunk lid for something and noticed part of the latch assembly was just hanging there, not in the clips. I clipped it back in, and it worked! Not sure if that's the same issue, and sorry that was terribly vague. All I know is something was hanging when it shouldn't have been haha. It was a few years ago and I've slept a lot since then.
