Knowing how to open your car's fuel door is essential, especially in emergencies. While the process may vary across car models and manufacturers, the standard method involves pressing the 'gas button' on the driver's side of the dashboard. However, sometimes, the fuel door may not open as expected, which could be due to a broken spring, dirty hinges, or a dead car battery. In such cases, you can try using a screwdriver or prying the door open with a pocket knife, credit card, or flat object. Alternatively, some car models have a manual release lever in the trunk, which can be pulled to open the fuel door.

What You'll Learn
Using a screwdriver
If your fuel door is stuck shut, there are a few methods you can try to open it with a screwdriver. Firstly, check if your car has an emergency release for the fuel flap; this is usually located in the trunk, around the fuel door area. If you find this lever, you can try pulling it while someone else uses a screwdriver to pry the fuel door open from the outside.
Alternatively, if you can hear the mechanism working but the door won't unlock, you can try using a flat-head screwdriver. Insert the screwdriver into the gap between the fuel door and the car body, opposite the hinge, and apply pressure outwards to pry the door open. You can also try bending the catch on the fuel door inwards slightly with the screwdriver so that the latch doesn't have to open as far to release the door. Be careful not to bend it too far, or the door won't close properly.
If you can access the spring mechanism behind the fuel door, you can use a flat-blade screwdriver to bend it and make it easier to open the door in the future. However, this method requires you to reach the spring without removing the assembly from the car, which may be difficult in some vehicles.
As a last resort, you can attempt to remove the fuel door entirely with a screwdriver, but this will leave your car without a fuel door.

Leveraging a credit card
If your car's fuel door is stuck shut, you can try leveraging a credit card to open it. This method can be particularly useful if the release lever inside the car is not functioning correctly.
Firstly, locate the release lever or button. In most cars, this will be near the bottom of the driver's seat, close to the driver's side door. If there is no lever or button, your car likely uses a locking gas cap, which will require a key to open.
If you have identified a release lever or button, but the fuel door still won't open, you can try using a credit card (or another flat object) as a lever. Insert the card into the gap between the body and the door, opposite the hinge, and pry the door open. You may need someone to hold the lever or button engaged while you do this. Be sure to push the card away from the hinge, as pushing it towards the hinge could damage the door or the card.
If the fuel door is still stuck, you may need to access the mechanism behind the gas tank. To do this, open the trunk and remove the plastic access panel closest to the fuel tank. If your car does not have an access panel, you can try removing the cloth lining near the inside of the fuel tank. Once you have accessed the mechanism, you may be able to manually open the fuel door or identify any issues causing it to stick.
It is worth noting that some users have reported success with other flat tools, such as a screwdriver or pocket knife, in place of a credit card. Additionally, lubricating the mechanism or hinges with products like WD40 can help prevent future sticking.

Pushing the fuel door button
If your car's fuel door won't open, there are a few things you can try. Firstly, check if your car has a fuel door button, which is usually located on the driver's side dash inside the car. If you can locate the button, simply press it, and you should hear a click, indicating that the fuel door has been unlocked.
If the fuel door still doesn't open after pushing the button, try applying some force by pushing or prying the fuel door inwards while simultaneously pressing the button. This may require two people, with one person pushing the button and the other pushing or prying the fuel door. This additional force may be necessary to release the latch and pop the fuel door open.
In some cars, the fuel filler door can be opened manually by pulling a lever located in the trunk. This lever is typically labelled with a warning sign. If you own a Lexus, for example, you can open the trunk with the mechanical key stored in the smart key and locate the cable that, when pulled, opens the gas cap.
If your car's battery is dead, it may not be able to detect your key fob, preventing the fuel filler door from opening. In this case, you can try the manual workaround described above or consult your car's manual for specific instructions.
If none of these methods work, there may be an issue with the latch release mechanism, such as a broken spring or gunked-up hinges. In this case, you may need to lubricate the hinges or consider replacing the spring.

Manually opening the lever in the trunk
If your gas tank door is stuck shut, you can try manually opening the lever in the trunk. Here's a step-by-step guide to help you with the process:
Firstly, ensure your car is turned off and parked. It's important to put the car in park before attempting any maintenance or repairs. Next, check that all the doors are unlocked. In most cars, the gas tank door won't open unless the car is turned off and the doors are unlocked.
Now, open the trunk and locate the access panel near the fuel tank. If your car has a cloth lining near the inside of the fuel tank, carefully remove it to access the mechanism. You may need a flashlight to illuminate the area. Once you've located the access panel, reach inside and feel for a small box with a lever on it. This is the locking mechanism for your gas tank door.
To manually open the gas tank door, press or pull the lever. You should hear a small click as you do this, indicating that the gas tank door has been unlocked. If the lever is hard to grab, you might need to pull it outwards to activate it. In some cases, you may need to apply pressure to the fuel door while pressing or pulling the lever.
If your car has a locking gas cap, insert the key and twist it counterclockwise to unlock it. Once the gas tank door is open, you can start pumping your gas. Remember to always shut the gas tank door securely before driving away.
It's important to note that the location and design of the manual release lever may vary depending on your car's make and model. Additionally, some newer cars may have a fuel release button on the driver's side door instead of a lever. Always refer to your car's manual for specific instructions.

Bending the spring
If your fuel door won't open, it could be due to a faulty internal spring or lever, lack of lubrication, or a bent fuel door. If the spring appears damaged, you may need to bend it to increase tension or replace it.
- Get a friend to open the gas door while you pull on the lever.
- Take a pair of pliers and locate the metal part with a hole attached to the gas door.
- Slightly bend the metal part to the left so that you can fit a nut and washer behind it.
- Take a standard clothespin and break it apart to retrieve the spring.
- Bend one side of the spring so that it wraps around the bolt. You can bend one of the ends that used to wrap around the wooden part of the clothespin into a hook shape.
- Put a washer on the bolt, followed by the spring, and then insert the bolt into the hole.
- On the opposite side of the hole, place another washer and then a nut.
- Tighten the bolt, ensuring that the components are in the correct order: bolt head, washer, bent spring end, hole in the metal part of the gas door, washer, and nut.
- Carefully close the door to check for any clearance issues.
Note: It is important not to bend the spring too much, as it may prevent the fuel door from closing properly. Additionally, consider covering the end of the spring with a soft material to prevent scratches and potential rust on the paint.
