Buying Locks with Same Key: Secure Your Home with Ease

When it comes to home security, installing high-quality locks is a crucial step in keeping your property safe. But with so many different types of locks available, choosing the right one can be overwhelming. One option worth considering is buying locks with the same key.

Using same key locks can make it easier to secure your home by allowing you to unlock multiple doors with a single key. This approach can also simplify the process of replacing or upgrading locks, as you only need to worry about one key fitting all of your locks. In this article, we’ll explore the benefits of using same key locks and provide a detailed guide on how to drill a circle lock if needed.

Key Takeaways:

  • Buying locks with the same key can simplify home security and make replacing or upgrading locks easier.
  • Drilling a circle lock requires specific tools and precautions, which will be covered in later sections.

Understanding Circle Locks: What You Need to Know

Circle locks are a popular type of lock used in homes and businesses to increase security. They are named for their unique circular shape and are designed to be more resistant to picking and drilling than traditional locks. Circle locks rely on a complex internal mechanism that makes them difficult to bypass without the right tools and techniques.

One of the key benefits of circle locks is their reliability. They are often used in high-security settings where protection against unauthorized access is critical. They are also known for their durability, making them a long-lasting investment for homeowners and business owners alike.

Pros Cons
High level of security Higher cost upfront
Durable and long-lasting Difficult to install
Resistant to picking and drilling Special tools required for installation and maintenance

It is important to note that circle locks should only be installed by a professional locksmith with the proper tools and expertise, as incorrect installation can compromise their security features.

How Circle Locks Work

Circle locks operate using a set of pins that are rotated by a key. When the correct key is inserted and turned, the pins align with the internal mechanism and the lock can be opened. The circular shape of the lock makes it more difficult to manipulate with lock-picking tools, as there are no traditional pins that can be easily accessed.

The locking mechanism is designed to be highly resistant to drilling, as it is made from hardened materials such as steel or tungsten. The internal components are also protected by anti-drill plates and other security features. This makes circle locks a more secure option for those concerned about potential break-ins or theft.

Choosing the Right Tools and Equipment for Drilling a Circle Lock

Drilling a circle lock is a delicate process that requires the right tools and equipment for a successful outcome. Using the wrong tools can damage the lock and make it impossible to open, leaving you locked out of your home.

When selecting the tools for drilling a circle lock, it’s important to consider the type of lock you’re dealing with. Circle locks typically require a drill with a carbide-tipped bit, as they are made of hardened steel. A high-speed steel (HSS) bit may not be strong enough to penetrate the lock’s surface, so it’s best to stick with carbide-tipped bits.

Tools and Equipment Description
Drill A drill with a variable speed setting is recommended, as it allows for greater control during the drilling process.
Carbide-Tipped Bits Choose a set of carbide-tipped drill bits in varying sizes to ensure you have the right size for the lock you’re drilling.
Drill Press Vise A drill press vise ensures the lock remains in place during drilling, reducing the risk of slippage or damage to the lock.
Protective Gear Wear eye protection and work gloves to protect yourself from debris and metal shavings generated during drilling.

It’s essential to choose the right equipment and ensure that it’s in good condition before starting the drilling process. Dull or damaged bits can cause the lock to overheat or become damaged during drilling, so it’s best to check your equipment beforehand.

In the next section, we will discuss the step-by-step process of drilling a circle lock.

Step-by-Step Guide: Drilling a Circle Lock

Drilling a circle lock can be a daunting task for those who have never attempted it before. However, with the right tools and techniques, anyone can successfully drill a circle lock. Follow the steps below to drill a circle lock effectively:

  1. Prepare the area: Start by removing any obstructions around the lock that may interfere with the drilling process. This includes removing any screws, bolts, or other hardware around the lock.
  2. Insert the drill bit: Choose a drill bit with a diameter that matches the size of the circle lock. Insert the drill bit into the chuck of the drill and tighten it securely.
  3. Create a guide hole: Position the drill bit in the center of the circle lock and apply light pressure to create a guide hole. This will help keep the drill bit in place and prevent it from wandering during the drilling process.
  4. Begin drilling: Slowly increase the speed of the drill and apply steady pressure to the drill bit. As you drill, periodically back the bit out to remove any debris that may have accumulated. Continue drilling until you have drilled through the entire lock.
  5. Remove the lock: After you have drilled through the lock, use a flathead screwdriver to remove the lock from the door.

Remember, drilling a circle lock requires patience and precision. Take your time and follow these steps carefully to ensure a successful outcome.

Tips and Best Practices for Drilling Circle Locks

If you’re planning to drill a circle lock, there are several tips and best practices to keep in mind. These techniques will help you avoid damaging the lock, maintain safety, and achieve success. Here are some suggestions:

  1. Positioning: Make sure the drill is centered on the lock and perpendicular to its surface. Use a compass or ruler to ensure accuracy.
  2. Pressure: Apply steady pressure to the drill while maintaining control. Avoid using excessive force, as this may break the drill bit or damage the lock.
  3. Lubrication: Use a lubricant, such as WD-40, on the drill bit to reduce friction and extend its lifespan.
  4. Cleanliness: Keep the lock and drill area clean and free of debris. Use compressed air or a soft brush to remove dust or metal shavings.
  5. Patience: Take your time and proceed slowly. Rushing can lead to mistakes and reduce the effectiveness of your drilling.

By following these tips and best practices, you can increase your chances of successfully drilling a circle lock. Remember to always prioritize safety and caution throughout the process.

Seeking Expert Help: When to Call in the Professionals

While drilling a circle lock may seem like a straightforward task, it is important to know your limits and when it is necessary to seek professional assistance. If you are inexperienced with drilling or lack the proper tools and equipment, attempting to drill a circle lock yourself can result in damage to your lock, door, or even personal injury.

If you encounter a particularly challenging circle lock or are unsure of your abilities, it is recommended to contact a professional locksmith. Locksmiths have the necessary expertise, experience, and tools to handle even the most complicated circle locks with ease.

Enhancing Home Security with Same Key Locks

Using same key locks is a smart way to improve home security. They offer convenience and efficiency, as well as cost-effectiveness. With same key locks, you no longer need multiple keys to access different parts of your home. Instead, one key fits all. This eliminates the hassle of having to keep track of different keys and ensures that all entry points are secured with just one key.

Another advantage of using same key locks is that they provide a high level of security. Burglars will find it difficult to enter your home if all entry points are secured with the same key. Additionally, it allows you to easily monitor access to your home as you will know who has a key and who doesn’t.

Investing in same key locks is also cost-effective. While they may seem more expensive at first, they can save you money in the long run. You won’t need to pay a locksmith to rekey your locks or replace them with new ones if you lose a key or if a key falls into the wrong hands. You can simply rekey your same key locks and only have to replace the lock itself if it becomes damaged.

In summary, same key locks offer a convenient, efficient, and cost-effective solution to enhance your home security.


Securing your home with same key locks is a simple and effective way to enhance your home security. By choosing to use circle locks and following the proper drilling techniques, you can ensure that your home is protected against intruders.
