I don't have the valet key. It is consistent every time. I called my dealer and she laughed at me..lol.

It happens every time, just don't know why. The first time it happened, I thought that I somehow hit the trunk release on the key fob, so the next time, I didn't touch the front of the key...

It just started yesterday evening, it's done it every time since then. Thr trunk isn't popped when I get in the vehicle, there seems to be nothing wrong with the interior release or the key. It's almost like it's doing me a favor by opening the trunk, I just don't want it to...lol.
