The Complete Guide to Changing a Commercial Lock: Tips and Best Practices

When it comes to maintaining the security of a commercial property, changing a lock is a fundamental measure that ensures safety and peace of mind. Whether you’re dealing with a recent employee turnover, upgrading your security, or addressing a malfunctioning lock, understanding the process of changing a commercial lock is essential. In this guide, we’ll walk you through the steps and considerations for changing a commercial lock, helping you keep your business secure.

Why Change a Commercial Lock?

There are several reasons why you might need to change a commercial lock:

1. Security Upgrade: Older locks may be vulnerable to modern lockpicking techniques. Upgrading to newer, more secure locks helps prevent break-ins.
2. Employee Turnover: When employees leave, particularly those with access to sensitive areas, it’s critical to change the locks to prevent unauthorized access.
3. Lost or Stolen Keys: If a key goes missing, the safest course of action is to replace the lock rather than risk it falling into the wrong hands.
4. Malfunctioning Lock: A lock that doesn’t work smoothly can be frustrating and may not provide the protection your business needs.
5. Business Relocation: Moving into a new office or building should always involve changing the locks, as you can never be sure who has copies of the existing keys.

How to Change a Commercial Lock: A Step-by-Step Guide for Business Owners

Maintaining the security of your business premises is crucial for protecting sensitive information, assets, and the safety of your employees. One essential aspect of this security is ensuring that your commercial locks are functioning properly and are up-to-date. Whether you’re addressing an issue with a faulty lock, improving security, or dealing with employee turnover, knowing how to change a commercial lock can be invaluable.

In this blog, we’ll walk you through the process of changing a commercial lock, explain the types of locks commonly used in businesses, and provide some best practices for selecting and installing new locks.

Why You Might Need to Change a Commercial Lock

Before we dive into the process, it’s important to understand the reasons for changing a lock on your commercial property:

1. Security Concerns: A lost key or a break-in attempt often prompts a lock change to enhance security.
2. Employee Turnover: If an employee with access to your property leaves on bad terms or misplaces a key, changing the locks prevents unauthorized entry.
3. Lock Malfunctions: Over time, locks can wear down and malfunction. Changing a faulty lock can prevent potential lockouts and security breaches.
4. Upgrading Security: Implementing high-security or electronic locks can provide better control over who has access to different areas of your building.

Types of Commercial Locks

Before starting the process, it’s crucial to identify the type of lock you have and decide on a suitable replacement. Common commercial locks include:

• Cylindrical Lever Locks: Often used for office doors, these locks are easy to operate and provide a high level of security.
• Mortise Locks: These are typically found on glass doors and provide a robust locking mechanism.
• Electronic Keypad Locks: For businesses that require keyless entry, electronic locks allow access through codes, keycards, or biometrics.
• Panic Bars: Also known as push bars, these are used for emergency exits and require special installation.

Step-by-Step Guide to Changing a Commercial Lock

1. Gather the Necessary Tools and Supplies

Before starting, make sure you have the following tools and supplies:

• New lockset (ensure it’s the right size and type for your door)
• Screwdriver (flathead or Phillips, depending on your lock)
• Allen wrench or hex key (if required for your lock)
• Drill (optional for certain lock types)
• Measuring tape
• Replacement latch (if needed)

2. Remove the Old Lock

1. Unscrew the Lock Screws: Locate the screws on the inside of the door and unscrew them using the appropriate screwdriver. Be sure to keep these screws in a safe place in case you need them later.
2. Detach the Lever or Knob: Remove the lever or knob by pulling it away from the door. If the lever is secured by a small screw, use an Allen wrench or hex key to loosen it.
3. Remove the Lock Body: Once the lever or knob is removed, gently pull out the lock body from the door. If it’s a mortise lock, you may need to loosen additional screws securing it to the doorframe.
4. Extract the Latch: The latch is located within the edge of the door. Remove the two screws securing it and pull the latch out.

3. Install the New Lock

1. Insert the New Latch: Slide the new latch into the opening on the side of the door. Align the screw holes and secure it with the provided screws. Make sure the latch is centered and operates smoothly.
2. Install the Lock Body: Position the new lock body into the hole in the door. For mortise locks, make sure the lock case fits into the door pocket snugly. Tighten the screws to secure the lock body in place.
3. Attach the Lever or Knob: Place the new lever or knob onto the lock body. If it has a set screw, use an Allen wrench or hex key to tighten it.
4. Secure the Strike Plate: On the doorframe, remove the old strike plate and replace it with the new one provided in the lockset package. This ensures that the latch properly aligns when the door is closed.

4. Test the Lock

Once you have installed the new lock, test it multiple times to ensure it operates smoothly. Check that the key turns easily, the lever or knob moves without resistance, and the latch fully engages with the strike plate.

5. Consider Rekeying the Lock

If you want added security, consider rekeying the lock, which allows you to change the lock’s internal pins without replacing the entire mechanism. Rekeying ensures that old keys will no longer work, even if someone still has them.

Best Practices for Changing Commercial Locks

• Choose High-Quality Locks: Invest in commercial-grade locks designed for durability and security. Look for locks rated Grade 1 or Grade 2 by ANSI/BHMA standards.
• Maintain Records: Keep track of lock changes and who has keys or access codes to ensure you can respond quickly if security concerns arise.
• Hire a Professional Locksmith: If you’re unsure about any step of the process, it’s always best to consult with a professional locksmith to ensure the lock is installed correctly and securely.
