Gene, thanks for confirming what I thought. Its always nice to get a second opinion.
kaygee, I'm not where I can take a picture right now but yes, it has s slot in the handle and the piece the key goes in also has a small slot to. At first glance you would think it keeps the key assembly from turning. However, the long key assembly goes through the handle and has a bolt on the end where its tightened up once the key assembly is in place.
In other words, install the trunk handle and once its in place stick the key assembly through the handle and the end will go through a hole in the trunk lid and then you put a nut on it and tighten it up.
Look at the end of the key assembly and you can see that it can't rotate once inside the actual latch assembly.
(I'll try to get a pic this weekend.)
