All you ever wanted to know about key duplication services but were afraid to ask – that’s what this article is about. It’s time to demystify the process of key duplication and ask the questions that are often times left unanswered.

First, let’s start with the basics. What exactly is a duplicate key? Simply put, a duplicate key is an exact copy – from shape to spacing between cuts, including lubrication, each copy must replicate the original key perfectly. Many people might try to make a copy from a photograph or sketch but that just won’t cut it.

The next question you might have is how to get a duplicate key made. There are a number of ways to copy a key, and you’ll want to go with the right method that will ensure a perfect fit. The most common approach is to take your original key to a locksmith and request a duplication. Much like a doctor’s office, the locksmith will have you fill out a form and you’ll get your copy almost immediately.

If you’re wondering how a locksmith can clone a key, even from just a physical specimen, we’ve got the answer: the process begins with a key cutting machine and a selection of specialised files and clamps. The original key is secured in the machine which reads the cuts and designs along the blade. Then, a specialised file is used to replicate and accurately reproduce the blade’s exact profile on the duplicate.

The blades of both keys are then measured with a micrometer to ensure the specifications are exact. As the edges of the cuts are created, the burrs are checked and eliminated and finally, the key is lubricated before being handed back to the consumer. Once you have the duplicate key in your hands, it’s time to give it a test run and check that it works perfectly with the lock.

These days, with the power of technology, many locksmiths offer digital key duplication services which use a 3D scan of the lock to create a perfect copy. This efficient method is becoming increasingly popular, as the process only takes a matter of minutes, and you don’t have to carry the original key with you to the locksmith.

Aside from having a duplicate key on hand so you don’t get anxious if you lose your original, there are a few other reasons you might want one: a person who lives with you might need a key as well, or you may want to keep a spare at a nearby location in case of an emergency.

Now that you have all the information you need to feel confident in your key duplication decision, the last thing to consider is where to get it done.

What is Key Duplication?

Key duplication is a process in which a new key is made to match and operate a specific lock. This process can involve copying either a standard factor or a special key.

Standard factor keys are able to be duplicated easily with minimal cost. These keys are simple, and often referred to as “one-offs,” meaning that there is only one of them in existence. Special keys, however, are much more complex. Examples include difficult-to-copy keys, copper keyways, and small warded keys. These keys require more skill and precision in order to be successfully copied.

The Process of Key Duplication

At Locksmith Columbus, we understand the importance of having secure keys for your residence or business. That’s why we make sure that the key duplication process is fast, easy, and reliable. Our locksmiths are highly trained and have the latest equipment and techniques to provide you with a low-cost key duplication service.

Before we get into our process, we first ask that you provide us with some basic information. This includes the manufacturer and model information about your lock, as well as an imprinted key sample. Having this information readily available helps us better assess the situation and determine the best key duplication solution for you.

Once we have all the necessary information, the next step is to create a key copy. Depending on the type and complexity of the key, Locksmith Columbus will use either the traditional key cutting method with a physical key duplicator, or a more advanced key duplication technique such as Computer Numerical Control (CNC) machining. For standard factor keys, we use a key cutting machine that machines the key to the exact size and shape specified. For special keys that may have special shapes, features, or angles, our locksmiths will use a CNC machine that accurately re-creates the shape of the key from a digital file.

Once the key has been cut, the final step in the process is to test the key to ensure that it works properly. This is done by inserting the key into the lock and turning the key several times. If the key successfully opens or locks the mechanism, then the key has been successfully duplicated.

Tips for Key Duplication

The key duplication process can be a confusing and time-consuming process if you’re not an experienced locksmith. To make sure that you get the best results possible when getting your key duplicate, keep the following tips in mind:

Always make sure that you provide accurate information when asking for a key copy. This includes the manufacturer and model information of your lock, as well as an imprinted key sample.

When inquiring about a key duplication, make sure that the locksmith is experienced with the type of key you have. If it is a special key, make sure that the locksmith has experience in key duplication with the relevant CNC technology and machines.

If available, it is best to provide the locksmith with a compatible key or as much information as possible about how the key was made.

Always remember to test the accuracy of the duplicate key with the original key, making sure to turn both keys several times in the same lock.

For commercial or residential settings, always keep a record of the total number of keys duplicated. This will help you keep track of your key inventory.


Key duplication is not an easy process, but it is essential if you want to ensure that your home or business is secure. Knowing the basics of key duplication services will allow you to have a better understanding of what is involved and the steps required to get a key duplicate.
