Are All Bike Lock Keys the Same?

No, they’re definitely not the same. Nor are they unique. Here’s what you need to know when it comes to your bike lock’s keys.


Have you ever wondered if all bicycle locks from one manufacturer have the same key, or if you actually need the key that came with your lock to open it?

Whether you’ve lost your bike key, have several different bike locks, or are just curious, it’s normal to wonder if you can unlock them all with the same key. After all, it would be convenient if you didn’t have to keep multiple bike keys on the key hook. However, it would also make it easy for thieves to get their hands on your bike.

Not all keys for bicycle locks are the same, and yet not every key is unique either. Manufacturers have a set of key-lock combinations that they randomly disperse as part of the production and distribution process.

In this article, we are going to talk about whether or not all bike lock keys are the same—and why it matters.

Are All Bike Lock Keys the Same? 

The long answer short is, no, all bike lock keys are not the same. But they’re not all unique either.


Let me explain.

To save time and money, bicycle lock manufacturers produce a certain number of key and lock combinations. These combinations are issued randomly to ensure that not all locks in a country, city, or even store can be unlocked with the same key.

By doing this, bicycle lock manufacturers can sell locks with a limited number of unique keys in every batch while still ensuring that your bike is protected from theft.

Before you start worrying about your bike being stolen, it’s important to know that the chances of someone coming across your bike with the same lock key are very—and we mean very—low.

So, at least as far as the keys are concerned, you can lock the bike safely and sleep soundly at night.

How Do Bike Lock Manufacturers Discourage Theft? 

If there are other bike locks with the same key as yours, you may be worried that someone will come and steal your bike. The good news is that bike manufacturers are also worried about this—and are doing everything they can to prevent it.

The last thing a lock manufacturer wants is to be known as the company whose locks can easily be broken into! So they pay special attention to this process. When assigning keys and locks coming off the assembly line, they try not to give out locks with the same key in the same batches.

In other words, they sprinkle different key-lock combinations into the batches so that there is no discernible pattern that potential thieves could exploit.

Can Someone Else Open My Bike Lock?

Let’s suppose that someone buys a bike lock from the same manufacturer as you do. If they happen to have the same key-lock combination as you do, they’d be able to open your bike lock.

The good news is that the likelihood of this happening is low thanks to the way manufacturers produce and distribute their locks. The same make and model bike locks get dispersed all over the country, and oftentimes all over the world.

So it’s very improbable that two people in the same city (or even the same state) would get the exact same key-lock combination. What’s even more improbable is one of them trying to unlock the other’s bike!

With that being said, it’s important to remember that a thieve would rarely try to steal your bike by checking if the keys they have fit the lock. They’d probably try to pick, break, or cut through it, taking the guesswork out of the process.

Can I Open My Bike Lock With Someone Else’s Key?

There’s always the possibility that you’d be able to open your bike’s lock with someone else’s key. This is disconcerning for those who are nervous about theft, but it really shouldn’t be.

Again, it would have to be a stroke of bad luck that someone who is looking to pick a bike lock tries your lock and happens to have the exact same key. So don’t worry about it and focus on parking your bike safely instead.

There are many things that you can do to protect your bike from theft, like locking the right tire, being smart about what you do when there’s no bike rack in sight, and making it harder to steal your bike when locking it together with the bike of a friend or family member.

Can I Make Copies of My Bike Lock Key?

Most key bike locks come with a set of two identical keys. This way, you have one key that you actively use to secure your bike—and another key that you can keep in a safe place in case you lose the first one.

If you’re worried about losing both of your bike lock keys, making a copy (or a couple) can be a good idea. 

Make sure you know where you hide your extra copies in case you need them. There is nothing worse than knowing you have the copies you need, but hiding them so well that you forget where you put them.

Locksmiths can typically make copies of your bike lock key, whether it’s a barrel key or a regular key. 

Even if your key says “Do Not Copy”, some locksmiths will still do it for you, especially if you can show proof of purchase (a receipt). The only caveat is that some types of bike lock keys, especially barrel keys, are becoming less popular, and not all locksmiths make them.

If you have a more obscure style bike lock key, locksmiths may not carry the blanks needed to copy your specific key in their store. It’s important to bring your key in and have them tell you whether or not they have it or can order it. 

Final Thoughts 

Not all bike lock keys are the same, but they’re not all different either. Chances are someone out there, or quite a few people, have the same bike lock as you.

Before you panic: There is a method to this madness that will keep your bike safe. Bike lock manufacturers can only design a limited number of unique patterns. Because of this, there is a limitation to how many different key and lock combinations each manufacturer can create.
