It's always locked unless you just want to leave the key in (it will stay in just fine by itself). I bought mine for $12 which I thought was pretty cheap. If you want a little hanger thing so it hangs I guess you could rig something up.

 

Private message comes to mind.

 

if you buy one of those don't buy the cheap ones, I had one on my 93 for a very SHORT time, the peace of crap jammed at the gas station and I really needed gas... luckily I had a screwdriver and pliers to get it unlocked... now I just don't fool with them...

my opinion if your gonna buy one of these see if they make them in stainless steel or something that a cordless drill can't get through...because what someone said above I'd hate for someone to come buy and dump something into my tank and kill my motor...

 

Yeah the news media already covered that one; and if you ever lock your keys in your truck, there are a few guys on here that know exactly what to do. It's really no secret, sorry.

Anyways.. too bad I dont have a TDI, that would be funny if somebody broke open my gas door and thought they were getting gasoline, heh.
