You’ll hear a small “thunk” as you pull the lever—that means the gas tank door is unlocked.
The button may also have a small lock and unlock symbol on it.
Your car may have a locking gas cap on it. If it does, simply take the key and insert it into the gas cap, then twist it counterclockwise to unlock it. If you live in a state where you don’t have to pump your own gas, don’t worry about unscrewing the gas cap—the attendant will do that for you.
If your car does not have an access panel, simply remove the cloth lining near the inside of the fuel tank. If you’re driving a vehicle without a trunk (like a truck), accessing the mechanism behind your gas tank may be difficult. Take your car to a licensed mechanic so they can access the mechanism for you.
Your car may have a manual release pin instead of a lever. If you reach inside and see a pin, simply turn the pin counterclockwise, then pull it out. If your gas tank door does not have a fuel release button or lever (meaning you push it to unlock it), have a friend gently pry the gas tank door upward as you press the manual release lever.
Sometimes, the gas tank door locking mechanism will stop working because a fuse has blown. If that’s the case, you can change the fuse yourself or take your car to a mechanic.
