I had the locking gas cap on my 2009. On the 09-14 generation, there was a single cover that opened when inserting the nozzle, with the locking mechanism and it was positioned a little way down the filler tube, so the locking cap could fit above it.
It appears on my 2016 that there are two actual covers that open when inserting the nozzle, a black dust cover right at the top of the filler tube and the normal, locking mechanism that requires the exact nozzle size to open.

2009:



2009 with cap:



2016:


Each requires the exact size nozzle be inserted before the cap opens (or the included funnel), but the black dust cap on the outside of the 2016 can be pushed open without that exact size nozzle.

Mechanism schematic for the 09 one:

 

Look at the bright side You got free hose thief got nothing. Put a lock on it thief will just poke a hole in your tank, take what he can and let the rest run on the ground.

 

Good thing there is an anti siphon feature down in there.

 

I'm not concerned at all about anyone tampering or otherwise with my fuel filler.

However, thanks for sharing the cut-away views of the mechanism. I have not seen this before and was curious about it.

 

I'd rather that than find they had drilled a hole in the tank and done it that way because they couldn't get in through the filler.

 

I've always thought about vandalism, how easy to dump salt or something in.

 

Dude, you should get some help for that, before you act on it!

 

Yes, good thing for that. It sure stopped the sand someone poured down it too!

 

How secure do some of you think these locking fuel doors are? A 79 cent screwdriver is all you'd need to get it off. Only thing it will do is cause more damage. And if you've made someone mad enough to worry about them pouring sand down your gas tank, you've got bigger problems to address.
