Breaking Open a Bike Lock: 5 Methods If You Lost Your Key

Losing your bike key can be quite frustrating, especially if you don’t have a spare key. A lost key can turn your whole day upside down. Fortunately, there are several solutions available. Whether you want to order an AXA bike key or are considering breaking open a bike lock, in this guide, we will discuss all the options. We will also cover what to do if you have a broken key in the lock.

Immediate Actions for a Lost Bike Key

In Europe, many people use their bikes daily. It often happens that someone accidentally rides off, locks their bike, and then discovers that the key is missing. However, don’t worry, there are simple steps you can follow to get back on the road as quickly as possible.

1. Check for a spare key: Do you have an extra one at home or at friends’ places?
2. Check if you have an AXA lock: With an AXA lock, you can often order new bike keys via www.fietssleutels.nl or directly from AXA, based on the number on the lock.
3. No spare key? Consider a locksmith or try to open your bike lock yourself. We will explain non-destructive and destructive methods below.
4. Call the police if in doubt: Sometimes it is wise to file a report, especially if you suspect your bike key has been stolen.

Method 1: Breaking Open an AXA Bike Lock with Jiggler Keys

In my experience, jiggler keys are one of the fastest ways to open an AXA bike lock. This technique works particularly well on older AXA models with wafer locks.

How it works:

Jiggler keys are specially shaped keys that mimic the shape of various key profiles. By inserting the jiggler into the lock and moving it while turning, you manipulate the wafers inside the lock.

My method:

1. Choose the right size jiggler – usually medium for AXA locks
2. Insert the jiggler into the keyhole
3. Apply light turning force while moving the key up and down
4. Experiment with different movements: wiggling, in-and-out motion, light turning
5. With the right combination of movement and pressure, the lock will pop open

From experience:

Most AXA locks with low tolerances open within 30 seconds to 2 minutes.

Method 2: Diamond Pick Technique for AXA SL7/SL9

For the popular AXA SL7 and SL9 models, I often use a diamond pick. I have applied this technique hundreds of times and it works surprisingly quickly.

The technique step by step:

1. Use a feeler gauge or thin tension wrench in the middle of the lock
2. Apply constant tension (about as you would turn a key)
3. Take the deforest half diamond pick
4. Slide the pick over the wafers on the top and bottom
5. Make a “raking” motion – quickly in and out of the lock
6. The lock often pops open within seconds

Pro tip:

AXA locks “Made in Holland” often have very low tolerances. This paradoxically makes them easier to open with this technique.

Method 3: Combination Lock as a Bike Lock

Method 4: Removing a Bike Lock – Destructive Methods

With a destructive approach, you inflict damage on the lock (and possibly your bike):

• Angle grinder, metal saw, or concrete shear: These methods are quick and effective, but be careful not to accidentally damage the bike frame.
• Screwdriver and hammer: With some older locks, you can force the lock open, but the risk of damage is high.

Method 5: Non-Destructive Methods (Lockpicking)

You can break open a bike lock without damage using lockpicking. Lockpicking is the art of manipulating the internal mechanisms without the original key.

• Lockpick Set: With a basic lockpick set and some practice, you can open a simple AXA lock.
• Techniques like “raking”: For simple locks, you can use the “rake” method. This allows you to quickly stir through the pins until the lock unlocks.

Broken Key in Lock? Here’s How to Get It Out

A broken key in the lock can be very annoying. However, it is not impossible to pull the key out. Here are some tips:

1. Tweezers or magnet: If the key is magnetic, a strong magnet can sometimes pull the broken piece out.
2. Pliers: Is a small piece of the key sticking out of the lock? Then you can grab that with pliers. You may spray some penetrating oil to move the key more easily.
3. Key Extractor: With a key extractor, you can grab stuck key parts.

Prevention: Always Keep a Spare Key Handy

To avoid hassle with your bike key, it’s smart to always keep an extra copy with friends or family. Also, consider:

• Regularly checking if your keys are still in good condition.
• Do not share your keys with strangers.
• Make sure you know where to find the number on the lock.
