can't steal my gas, sucker
By Joshua Doerschner
the cap is mostly black. the part that screws into your car is bright red. it matches my car which is cool. however, my gas opening is at an angle. this makes releasing the lock a bit tricky because you also have to hold the cap from spinning as you unlock and turn the key. i was hoping for a special type of quick-key, but it is just a mini version of a normal car key. recommended if you value your gas.

It gets the job done
By Kristina Thompson
I purchased this product to prevent tampering with vehicle (impurities in the gas tank) and possible theft of gas. As advertised, this model fit both my Chrysler LHS and my dad's Chevy Silverado perfectly.

The gas cap comes with two small silver keys, each labeled "GAS" that lock and unlock your gas cap. Essentially, when your gas cap is "locked", the outer part spins freely without loosening the cap. When you "unlock" it, it engages and you can unscrew the cap.

I was a bit disappointed that you have to actually relock the cap with the key in order to secure the cap again, but the extra five seconds this takes is a small price for the peace of mind of knowing that your vehicle, gas, and personal safety are a bit more protected.
