Query: decent locking cap

so im stuck driving a 96 dodge ram 1500 v8 and gas is horrible here in California. so bad in fact that people have been going out and siphoning gas out of other peoples tanks where i live so i got this to try and prevent that.overall it has done its job well, its a snug fit and locks securely.only complaint is that the key hole has a guard over it to keep it clean i suppose and its a hassle trying to get the key in because of that guard.past that its served my purpose well
