Review on 🔒 Sikawai Locking Gas Cap 10504 31780 77300-47020 Fuel Tank Filler Cap - Compatible with Toyota 4Runner, Camry, FJ Cruiser, Tundra, Sequoia, Nissan Frontier, Altima, Armada, Chevy Impala, Malibu, and More by Amrozi Papi

Works as advertised. I like that it clicks 3 times when the cap is inserted into the pen and clicks into place (the cap rotates). Turn the key a quarter turn and back and it will unlock to remove it - easy. The gas cap even fits in my cap holder so I can put it aside when I fill up. I would have liked a rope hanging from the lid, but that's a minor inconvenience.
