Title: Bought this to prevent fuel theft (and possibly being stuck somewhere)
Review: Fits 2005 GM Cadillac Escalade 2004 (non-screw type OEM).In locked position, the cap free-spins. In unlocked position, the cap twists with the turn, opening the fuel cap.The key only comes out in locked position (i.e. free-spin). This is a hassle, because I originally wanted to occasionally lock (e.g. parked in questionable neighborhood), and leave it unlocked most of the time. Now I carry both gas caps (OEM around home, and this locking one when I am on a trip).
