What does Locking gas caps do?

A locking gas cap does pretty much what it sounds like; it locks the cap of the gas tank on your motorcycle so that it can’t be messed with. Which means you need to unlock it to be able to open it and put more fuel in. Another benefit of locking gas caps are that it keeps the gas cap from shifting or coming off while driving your bike. But it can be a hassle if you’ve lost or forgotten your key and need to get into the tank. Which is why it’s also a good idea to make a backup key and have it handy. It’s important to note that the locked gas cap may be slightly different from one bike to another. Some methods for getting the cap open are better on certain bikes than other. It just depends on what your bike is like so keep that in mind.

Have a new key made

Possibly the easiest and logical option to solve this problem is to have a new key made. You should be able to take it to a local locksmith who will be able to make a key for the gas tank, allowing you to open it with ease. This is a very simple solution to the problem. However, this solution will take some time and it will cost money so if you need to get into the gas tank right away and you don’t want to pay, then you may want to go with a different option. Also, this solution won’t be ideal if for some reason the locking mechanism is broken. In that case, you’ll want to take it out and replace it.

Use a drill

If you don’t want to have a key made, another good option is to use a small 1/8 drill bit and drill into the hole where you would normally insert they key to make it a little bit wider. Drill into the lock and then bore it out so that you have enough room to fit a screwdriver down into it. Be careful not to drill down to far though or you could get sparks into the gas tank and cause it to ignite. Which would not be a great situation. Only drill down as far as the key would normally go in. Then you can use a flathead screwdriver to turn the lock and open the cap. This is a pretty simple and effective method as long as you don’t mind destroying the lock.

Pick the lock

But let’s say you don’t want to mess up the keyhole by drilling into it, because you maybe have the key at home or are getting a new one made and still want to be able to use it properly. In that case you can simply pick the lock. This may require some finesse on your part but with the right tool it’s fairly simple. You’ll need a small metal tool to create tension while you use a small metal pick to pick the lock.

You’ll need to wiggle the pick around while you place tension on the system with the other tool. Wiggle it around until you can use the tool that is creating tension to turn the lock and unlock the cap. This can also be done with a small pocketknife or other small instrument by jamming it into the lock enough so that you can turn it and open the cap. If for some reason you can’t quite seem to figure out how to pick the lock, go this a different method.

Remove the entire cap

If none of these methods work for you, you’ll need to remove the entire gas cap from the bike. This can be a little bit tricky and will probably take some prying. The way to do this may also change slightly depending on how your bike is built. If the locking gas cap is screwed down, you can start by unscrewing it and then prying it up with a flat screwdriver. Or if there aren’t any screws just go in with the screwdriver until you can pry it up. It may take some work but this method is good if for some reason the locking mechanism is broke and turning it doesn’t open the cap. This is also a good option if you plan on replacing the cap and maybe add a non-locking one instead because you’ll already have it off.


There are many ways to get a locking gas cap off a motorcycle. Depending on your skill level and how much you want to damage the bike or not, some methods may be more suitable than others. And if you’re not an experience lock picker, then it’s a good way to practice your picking skills. Most locking mechanism on motorcycle gas caps aren’t too complicated though so it should be relatively easy to pick your way into them.

Because although they are made to make the fuel tank more secure, they aren’t designed to be an impenetrable fortress that you can’t get into. Any one of the above methods should work for you or you could even come up with your own method for opening the gas cap. Especially if you’re not afraid of damaging the bike, then it’s okay to play around a bit and use more forceful methods to get the gas cap off.
