Locking Gas Cap

My take

I tried this thinking it would be great to keep my gas cap nice and snug and add a little security to my Jeep, since it was designed to have easy, open access. Turns out this is not a good combination for cold weather use - or in general. My major problem with this was the first time I needed gas, the key would not unlock the cap. Not matter what I tried, it would not unlock, until about 15 minutes later. (I was fiddling at the pump the whole time) I promptly returned it as that kind of delay or risk of being stuck without a way to fuel is simply not worth it.
