Review on Motorad MGC 791 Locking Fuel Cap by Marcus Dortch

The cover works fine but it turns off the horn and turns on the check engine light. Unfortunately, the Toyota dealer told me this would happen all the time and would set off emissions codes that would cause those bulbs to go out. Toyota has stated that there is no fuel cap that works that will not fit the all-new Toyota 4 Runner. The lid itself worked as advertised. The only reason I give it 3 stars is because the check engine lights went out and I had to go to the dealer to reset it. I tried resetting them myself from all the hacks I read online but they didn't work.
