How to Rekey a Lock Using Professional Locksmith Tools

 

Rekeying is one of the most essential services a locksmith can offer. Instead of replacing the entire lock, rekeying a lock allows you to change the key combination so that old keys no longer work. For locksmiths and DIY enthusiasts alike, knowing how to rekey a lock with professional locksmith tools is a valuable skill that saves time and money.

In this guide, we’ll explain what rekeying is, the locksmith tools you’ll need, and a step-by-step process to rekey locks like Schlage and Kwikset using rekey kits.

What Does It Mean to Rekey a Lock?

Rekeying a lock involves adjusting the pins inside the lock cylinder to fit a new key. Instead of replacing the entire lock hardware, a locksmith simply removes the cylinder, rearranges or replaces the pins, and sets it to work with a new key cut.

This process is ideal for:

  • Homeowners who lost their keys
  • Landlords changing keys for new tenants
  • Businesses improving security
  • Locksmiths providing fast, affordable security solutions

Professional Locksmith Tools Needed for Rekeying

To rekey a lock properly, you’ll need a professional locksmith rekey kit and a few essential locksmith tools. Here’s a breakdown:

  • Rekey Kit (e.g., Schlage Rekey Kit, Kwikset Rekey Kit): Includes pins, springs, follower tools, and other essentials.
  • Plug Follower: Used to push the lock cylinder plug out without losing pins or springs.
  • Pinning Tweezers: Precision tweezers designed for handling tiny lock pins.
  • Key Decoder or Gauge: Helps identify the correct key cuts and pin sizes.
  • New Key Blanks: The keys that will work with the rekeyed lock.
  • Pinning Mat: Keeps pins organized while rekeying.

Locksmith suppliers like CLK Supplies provide high-quality rekeying kits and locksmith tools for both professionals and beginners.

Step-by-Step: How to Rekey a Lock

Here’s a straightforward process for rekeying a lock using professional locksmith tools:

1. Remove the Lock from the Door

Use a screwdriver to remove the lock hardware. This gives you access to the cylinder.

2. Take Out the Lock Cylinder

Insert the current key into the lock and turn it slightly. Use a plug follower to push the plug out of the cylinder housing carefully.

3. Remove the Old Pins

With the plug exposed, dump out the existing pins. These pins are matched to the old key, which will no longer be used.

4. Match New Pins to the New Key

Using a rekey kit, identify the correct pins for your new key by measuring the key cuts with a gauge or decoder. Insert the new pins into the plug.

5. Reassemble the Lock

Carefully slide the plug back into the housing using the plug follower to keep pins and springs in place.

6. Test the New Key

Insert the new key and turn it to ensure smooth operation. If it sticks, double-check pin sizes and alignment.

7. Reinstall the Lock

Place the lock back in the door, secure it with screws, and test the new key again.

Benefits of Rekeying with Professional Tools

  • Cost-Effective: Rekeying is cheaper than replacing entire locks.
  • Fast & Efficient: With the right locksmith tools, a lock can be rekeyed in minutes.
  • Increased Security: Old keys no longer work, ensuring peace of mind.
  • Professional Results: Using a Schlage rekey kit or similar professional tools ensures precision and reliability.
