Review on Gates 31778 Locking Fuel Tank Cap: Secure Your Fuel with Advanced Locking Technology by Jesse Wells

The lock must be broken! It won't close no matter how hard I try to latch the lid, it still unscrews. Don't waste your money on this. TO UPDATE. After many tries, I was finally able to figure out the trick. Screw it in, then hold it with both hands and try to fix it. Will keep it for a while.
