So my 2011 have the commonly seen key lock cylinder in the rear bumper which obscures access to the spare tire winch. Maybe not super secure, but better than nothing and more importantly in fills the ugly hole which it fits in. Well, mine seems to rust and get stuck. Not sure much the key cylinder itself but the little amrs which lock it into the bumper rust and swell and become too tight to turn with my ignition key as designed.
Now, this has always been easily remedied with a shot of penetrate into the key slot; but of course the day I need to use the spare I will undoubtedly NOT have access to penetrating oil. In the past, I've tried everything from fluid film, boeshield T9 and various other penetrating oils. Fluid film worked the best but you end up with the grimy fluid film and dirt build up... Which I guess is better than a frozen lock. Nothing else really holds up that well.
Any other suggestions? Seems to be in a a fairly washed out and dirty area up in the rear bump there. Here's a pic of my type of setup.
