How to Rekey a Schlage Commercial Lock？

A commercial lock serves as a critical security feature for businesses, protecting assets and ensuring safety. However, when you need to change access quickly or improve overall security, rekeying the lock is a cost-effective and efficient solution. Schlage, a trusted brand in commercial locks, offers locks that are designed to be secure, durable, and easy to rekey.  

This detailed guide will walk you through the process of rekeying a Schlage commercial lock. By the end of this blog, you’ll understand when to rekey a lock, the tools you'll need, and the step-by-step process for getting the job done.  

Why Rekey a Schlage Commercial Lock?  

Rekeying involves changing the configuration of the lock’s internal pins so that the old keys will no longer work. Here's why you might consider rekeying your Schlage commercial lock:

1.Lost or Stolen Keys

If a key is lost or stolen, it’s critical to secure your business by rekeying the lock to prevent unauthorized access.  

2.Employee Turnover

When employees leave the company, especially under questionable circumstances, rekeying ensures your premises remain secure.  

3.Consolidating Keys

If you’re tired of juggling multiple keys for different locks, rekeying can unify them so one key opens them all (keyed-alike system).  

4.Enhanced Security

Having up-to-date and secure locks is a proactive step in maintaining the safety of your business. Rekeying is significantly cheaper and faster than replacing an entire lock.  

Tools You’ll Need to Rekey a Schlage Lock  

Before you begin rekeying your Schlage commercial lock, gather the following tools and materials to ensure a smooth process:

● A Schlage rekeying kit (available online or at hardware stores)

● The original key (needed to disassemble the lock)

● The new key you’ll be using going forward

● A plug follower

● Tweezers or small needle-nose pliers

● A flathead screwdriver

● Pinning chart (to match pins to the new key cuts)

Having these tools handy will make the process faster and more efficient.

 

Step-by-Step Guide to Rekey a Schlage Commercial Lock  

1. Remove the Lock Cylinder  

  The first step involves removing the lock cylinder from the door. Using a flathead screwdriver, carefully detach the lock from the door following these steps:

  - Unscrew the screws on the lock’s cover plate.  

  - Remove the housing to access the lock cylinder.  

  - Slide out the cylinder for rekeying.  

  Pro Tip: Keep all screws and small parts in a safe place to avoid losing them.  

2. Insert the Current Key and Turn  

  Insert the existing key into the lock cylinder and turn it slightly, typically at a 90-degree angle. This unlocks the plug, allowing it to be pushed out.  

  It’s important to use the correct key here. If you no longer have the original key, you may need to contact a locksmith to decode the lock.  

3. Use the Plug Follower to Remove the Plug  

  Carefully slide the plug out of the cylinder using the plug follower. The plug follower prevents the bottom pins and springs inside the cylinder from falling out. Here’s how to do this:

  - Align the plug follower against the back of the plug.  

  - Apply even pressure while pushing the plug out gently.  

  Be sure to keep the plug follower flush with the cylinder to avoid any pins or springs from escaping.  

4. Replace the Pins in the Cylinder  

  Once the plug is out, you’ll see a series of small pins. Each pin corresponds to a specific cut on the key. Here’s how to replace them:

  - Refer to the pinning chart included in the rekeying kit.  

  - Using tweezers, remove the old pins from each chamber in the plug.  

  - Insert the new pins according to the chart, ensuring each pin matches the cuts on the new key.  

  Pro Tip: Double-check the pin heights to avoid jamming the lock. Test the new key in the plug to ensure it slides in and out smoothly.  

5. Reassemble the Lock Cylinder  

  Once the new pins are in place, carefully slide the plug back into the cylinder using the plug follower.  

  - Ensure the plug is aligned correctly to avoid damaging the pins.

  - Turn the key to the neutral position to lock the plug in place.  

6. Reinstall the Lock  

  Attach the lock cylinder back into its housing and reassemble the lock on the door by reversing the removal steps. Be sure to tighten all screws securely.  

  Insert the new key and test the lock. If it works smoothly and the old key no longer functions, congratulations! You’ve successfully rekeyed your Schlage commercial lock.
