If you lose a disc lock’s key and don’t have a duplicate, you will be left with a lock that cannot open. Disc locks are a secure padlock option with a circular design that protects against unauthorized access. 

When you don’t have a key, you are left with two primary options. The first option is to damage the lock’s internal components to release the shackle. If you aren’t going to use the lock again, this is the most inexpensive option to open it.

However, if you want to keep the lock functional, you can also pick the lock or hire a professional. You will likely need a professional locksmith if you have a high-security disc lock like the Abus Diskus Padlock.


5 Ways to Open a Disc Lock Without a Key 

Drill the Keyway Out

One of the most popular ways of accessing a padlock without a key is by drilling the keyway out of it. By drilling the internal components of the disc lock, you can release the lock shackle and take off the padlock.

However, this process is easier said than done, as lock keyways have durable metals like brass and steel. For premium-grade locks, you will typically need a drillbit made of titanium if you want to open it quickly. 

When drilling the disc lock keyway, you can push it on the surface while you slowly make a hole in the lock. If you need help securing the lock to prevent movement, you can hold the lock with a pair of vice grips. 

Pick the Disc Lock

Lockpick tools are the cleanest way to access your disc lock without a key. You can access your disc lock by picking the internal pins. However, picking a lock can be challenging if you are inexperienced and don’t have the correct tools. 

Lock manufacturers have incorporated several safety features that make picking a padlock difficult. Without lockpicking experience, you will need a lot of practice to access your disc lock without a key.

Depending on the design of your lock, you can utilize a bump-picking technique to open the lock quickly. However, this style of lockpicking has become more difficult as locks have become equipped with bump-proof pin cylinders. 

Use a Cutting Torch

You can utilize a cutting torch when you want to open a disc lock without a key in the fastest way possible. The extreme heat of the cutting torch will slice through the shackle of the disc lock like butter. 

If you have a hand-cutting torch, it can melt the body of the lock or hold the flame on the lock’s shackle. Either method you choose, you can notice the lock’s metal turning red before it eventually breaks. 

While this is the fastest method to open a lock without a key, it can be quite dangerous if you haven’t used it before. You should ensure nothing flammable is nearby and have wet rags to cool your hand while holding the torch. 

Hire a Locksmith

Since lockpicking can be challenging, you should hire a professional. A locksmith has the skills and experience to open a disc lock without a key. Most locksmiths have years of experience picking various lock types for customers.

The average cost of a locksmith in the United States is $150 for a standard service. If you need emergency services to open your disc lock, you can expect a price tag between $200-$300 for a locksmith. 

Depending on the circumstances, the locksmith may be able to create a new key for your disc lock. We recommend consulting a professional locksmith if you don’t want to destroy the lock to open it. 

Use an Angle Grinder 

Angle grinders are an effective way to cut a lock if you don’t want to rent a cutting torch or pick the locks. Use a strong metal-cutting disc and position the angle grinder to cut the lock’s shackle. 

You must wear the proper personal protective equipment when operating an angle grinder. The sparks caused by the angle grinder can cause fires and damage your eyes if not handled carefully. 

If you are in a location without electrical outlets, you can rent a battery-powered option to cut the disc lock. The process should be rather quick, but you should ensure that you are cutting the lock and not the hasp for the lock.
