- Lever Handle Locks: Often used for interior doors in commercial spaces, offering easy-to-use functionality.
- Mortise Locks: These heavy-duty locks are embedded into the door, offering a high level of security.
- Keyless Entry Systems: Perfect for businesses and smart homes, these allow entry without a physical key, providing a more convenient security solution.
2. Tools You’ll Need for Changing Locks
To successfully change a lock, you need the right tools. Here’s a basic list:

- Pliers
- Hammer (for removing old hardware)
- Pencil (for marking positions)
3. Prepping for a Lock Change
Preparation is essential to ensuring your new lock fits and operates smoothly. Here’s how to prepare:
- Measure the Existing Lock: Before purchasing a new lock, measure the diameter of your current lock’s hole and backset to ensure a proper fit.
- Choose the Right Lock: Based on your security needs, select the right type of lock, whether it’s for exterior or interior use.
- Remove the Old Lock: Unscrew and carefully remove the existing lock, making sure to clean the area around the lock hole.
4. Step-by-Step Guide to Changing the Lock
Once you’ve chosen your lock and prepared the space, follow these steps:
- Position the New Lock: Insert the new lock’s latch into the hole on the door edge, ensuring it sits flush.
- Secure the Lock: Insert the lock body into the door, aligning it with the latch. Use screws to secure the lock and ensure it’s tight.
- Attach the Lock Cylinder: For deadbolts or keyed locks, insert the key cylinder and ensure it aligns with the hole in the door.
- Test the Lock: After installation, test the lock by turning the key or handle to ensure smooth operation.
- Install the Strike Plate: For exterior doors, install the strike plate on the door frame for added security.
5. Common Mistakes to Avoid
Lock changing can be tricky. Avoid these common mistakes:
- Mismatching Lock Size: If your new lock doesn’t fit the existing hole, it can lead to security vulnerabilities.
- Ignoring Strike Plate Installation: Skipping this step can compromise the strength of the lock, making it easier for forced entry.
- Not Testing the Lock: Always test the lock to ensure it works properly before completing the job.
- Improper Alignment: Make sure the lock aligns with the door and frame for smooth operation.
6. Additional Tips for a Professional Finish
- Opt for High-Security Locks: Consider upgrading to high-security locks for added protection, especially on exterior doors.
- Weatherproofing: For exterior locks, use weather-resistant materials to prevent wear and tear from outdoor elements.
- Rekeying Options: Instead of replacing the entire lock, you can opt for rekeying, which changes the internal pins while keeping the exterior hardware intact.
7. When to Call a Professional Locksmith
While many homeowners can handle simple lock changes, certain situations require professional expertise:
- Complex Locking Mechanisms: If you’re installing a high-security or smart lock, it’s best to consult a locksmith to ensure everything works smoothly.
