How Does Key Cutting Work?

Key Cutting is one of the most essential services provided by locksmiths and key duplication companies. While the process may seem simple, it requires a high level of precision and skill. Whether you need a duplicate set of keys for yourself or as a spare, or are replacing an old or broken key, knowing how the process works can help you understand what to expect and make the best choice in your situation.

The key cutting process entails creating an identical copy of the original key using a key duplication machine. A flat key is inserted into the machine and moved across a blade that intricately cuts the structure of the key based on the original key’s shape. The new key is then shaped and polished to ensure smooth operation. This type of service is often needed for people who have lost their keys or want to ensure that a spare key is available for guests or other family members in the event of an emergency.

There are many reasons you might need to have a spare key cut, but the most common is that you’ve lost your original keys. Losing your keys can be a stressful experience, especially if you’re not sure how to get back into your home or car. In this case, key cutting can help you get into your home or vehicle quickly and safely.

If you’ve had your keys stolen or the blade snapped off in a lock, key cutting can also be helpful. This is particularly true for vehicles, where you might have an extra in the ignition or another place where a spare can be easily accessed. In these cases, a professional can cut and program a replacement key in no time.

Getting a spare key cut is also a good idea if you plan on sharing your key with a friend or other family member. This way, if the key is lost or accidentally locked inside the house, you can still gain access without having to call for emergency assistance.

How long it takes to have a key cut will vary depending on the type of key you need. For example, standard house keys generally take less than a minute to cut, while mortice (lever) or Chubb keys can take longer.

When choosing a company to cut or reprogram your keys, look for an established company with a good reputation. This will indicate that they have a deep understanding of the industry and can provide you with the most precise results. They should also be able to answer any questions you may have about the process or its benefits. Lastly, they should have the right equipment to handle all your key needs, including rekeying locks and recutting keys. This will give you peace of mind that your keys are in the hands of an experienced, trustworthy technician.
