Personally, I'm not a fan of locking gas caps. I lost the key and with a Google search found that I could in one tap with a hammer and nail completely lock the cap and remove it. Basically I'm saying the cap is so easy to negate that it isn't really a good option and that there are better options like anti-siphon device in tank.
I here ya. IMO, it will keep the majority of the thiefs away. My buddy woke up to a 1/4" hole in his empty tank, so if they want your gas, they will get it regardless.
