In the beginning I didn't know it locked with the car either. Usually these doors just push to open on other cars. And the first time I opened the lid to put in gas, I didnt have to push the unlock button. When I went home I checked to see if I locked the gas cap tight enough, but it wouldn't open. So I thought maybe something got stuck and I push a little harder than usual and the locking mechanism broke. It works just fine though and it doesnt open on its own or anything like that. I know there are other people on here who has had that happen.
