Welcome and congratulations. You are in the right place for 928 knowledge.

However, this thread is.....

Try pushing down on the hatch area as you turn the key in the tumbler. Check to see if you have different keys, one for ign, one for doors and hatch. It's happened before. Welcome.

 

Spray lubricant in the keyway and push down as docmirror suggested.

 

welcome

 

It is possible to unlatch that hatch from inside if everything else fails, but it involves drilling so not your first choice.

 

I just found some great stuff for stuck lock tumblers, called 3 in 1 lock dry lube. You can find it on Amazon.
