I just wanted to inform you when you replace a factory gas cap with a locking gas cap you run a very high chance of a evap code to set in the pcm module on cars and trucks,but only on newer cars and trucks from about 1999 and up. Causing a check engine light to come on in the dash and in most cases making your car run rough or not allowing your car to start. This is cause by an improper seal from the locking gas cap not allowing the evap system to create enough vacuum and pressurise. So I know there is problems with people stealing gas, but it is not worth it to to risk your car not being able to run right or even being able to run at all.
