How to Fix a Bike Lock That Wont Unlock: Ways You Can Try

It was a sunny day at the beach. You were enjoying a walk with your family when you remember that you left the bikes unlocked. Suddenly, you realize that the lock won’t open! In this post, we’ll be discussing some common reasons for bicycle locks not unlocking and how to fix them

Common Reasons for Locks Not Unlocking

Check if the Lock is Soldered or Cut To fix a lock that won’t unlock, try to check if the lock is soldered or cut. If the lock is soldered, you’ll have to replace the entire cable, including both the connector and locking mechanism. If the lock is cut, you will need to repair the damaged part and fasten it to the rest of the parts.

This is a very good idea to know because it helps you to know if your lock is worth fixing or not. If the Lock is Cut If the lock is cut, then it is necessary to fix it properly. If the lock is cut, you should take out the entire cable so that you don’t damage the rest of the lock.

You should use a wide-toothed drill bit and start a clean cut with the proper level. If you use a wire stripper, it is advised that you use only the rubber side of the stripper.

The lock is frozen

Many of us don’t know this, but this is exactly what is happening. Bike locks are designed so that they stop working if the heat source is too low for a long time. And this is precisely what is happening. So, if the lock is too cold, your bike will be locked for eternity.

You can solve this by leaving the lock open and airing up the bike for a while. If the heat source is still cold, you can warm up the lock by cycling on a warm surface (if you don’t have a garage or shed where you can store your bike), or heating up the bike by heating it with an oven for a few hours.

A bike lock cable can get stuck or even pull apart. If this happens, try warming the cable for a while.

Rust on the lock

The main reason that a bicycle lock doesn’t unlock is that it has been submerged in rust. These rust-locks are known to destroy even the strongest of them. Bad or missing splines on the lock One of the main problems with bad or missing splines is that they don’t stay put while you’re driving the bike, therefore they won’t unlock the lock.

To overcome this issue, it is essential to replace the bad splines. No maintenance is needed when using aluminum locks. But when using steel locks, it’s necessary to maintain them so that they can keep the bike locked properly.

To avoid the cost of damaging your bike, consider using high-grade bicycle locks. Clean the spokes and chain The spokes and the chain get damaged over time.

Your key got stuck in the lock

This is one of the most frequent reasons that bikes are found deadlocked. What makes this a common problem is that people sometimes leave their bikes locked with a key and let them idle for some time until the lock becomes stuck. This problem is easy to solve.

Before you go down the locksmith alley, try applying heat to the lock, or even try tearing it with a pair of scissors. You forgot to lock the bikes when you went to a friend’s house When you meet your friends at a party, you usually leave your bicycles locked with a simple lock.

This is because you know that most people prefer to walk home, rather than ride a bike for a short distance. But, the moment you leave, you have no idea where your bicycle is.

How to Fix a Lock That Won’t Unlock

If your bicycle lock has stopped unlocking, you will want to know why and how. Once you know, you’ll be able to fix the problem to the best of your abilities.

1. Locks are too Tight A too tight bike lock is one of the causes of bike locks that don’t open. You might want to try increasing the gap between the key slot and the outer casing using a little sawing. This can be tricky as your blade could easily cut into your lock and mess up your locks.

Unfreezing the lock

The most common mistake people make when there’s a problem with their bike lock is that they won’t check whether the bike lock is frozen. Unfortunately, there is no such thing as a “frozen” lock. The only thing that can happen is that the inner core of the lock is no longer tight or the locking mechanism is not functional.

If you start to hear the clicking sound, it means that the lock is frozen. This is a deadlock. Unfreezing the lock requires you to pull the locking mechanism apart. It’s not a big deal if your bike lock is the old kind that doesn’t have a “hacking” mechanism.

Removing rust with WD-40

Rust is quite a common problem among most bicycles. It is very easy to deal with rust on a bike lock. Just simply spray WD-40 on the rust spots and the rust will be dislodged. Brake Obstruction Often, bikes are parked in a tight space and often lock our wheels with the brake lever.

This leaves us with no way to use the brakes! Most people store their bike locks in a toolbox or on a closet shelf, which isn’t the most convenient place to store your lock. That is why it is essential that we keep our bikes in the most convenient place and check for brake obstruction on a regular basis.


Bike locks will work if you don’t lock it up with only the strong (reinforcing) bicycle lock. If you try to lock it with any other combination, then it won’t work. The lever lock with the key type is not recommended since it is not strong enough for a heavy bike lock.

A cheap lock and key combination is highly recommended because it is the cheapest, but it might not be so good for your bike. If you need some more information, you can read our other posts on how to fix a bicycle lock that won’t unlock and bike lock and bike key combination here and here.
