I have never had this problem but there are a couple of links here. Most for roadsters though.
Have you checked to ensure the air line to the lock is intact?
Check out this one in the link below.

Hope this helps. There is also a video that had the same problem.
Of course another roadster. There was a whole series on that car in the UK.
If I remember right it had a plate blocking access that was only in Europe.
I could be wrong.
