How to Rekey a Door Lock Easily: A Complete Guide

Rekey a Door Loc

In today’s fast-paced world, securing your home or property has never been more crucial. With security concerns on the rise, taking proactive steps to ensure the safety of your belongings and loved ones is essential. One often overlooked yet effective security measure is rekeying door locks. This method offers both flexibility and enhanced protection without the cost and hassle of full lock replacements. In this comprehensive guide, we’ll explore the ins and outs of how to rekey a door lock easily, so you can keep your premises secure.

Understanding Rekeying

What is Rekeying?

Rekeying a door lock involves altering the lock mechanism so that a new key can operate it while the old one cannot. This process does not require the entire lock to be replaced, just the internal components that interact with the key.

Rekeying vs. Replacing

The main difference between rekeying and replacing a lock lies in the approach and cost. Rekeying is generally less expensive and entails modifying the existing lock to accept a new key. On the other hand, replacing a lock involves purchasing and installing an entirely new hardware, which can be more costly and time-consuming.

When to Consider Rekeying

Rekeying is most suitable in scenarios where you want to ensure that old keys no longer grant access to your home or property. This might include:

  • After moving into a new home.
  • If keys are lost or stolen.
  • To prevent access by previous occupants or service personnel.

Advantages of Rekeying Over Lock Replacement

  • Cost-effectiveness.
  • Maintains the aesthetic of your existing hardware.
  • Allows all locks to be operated with a single key when they are of the same brand or type.

Step-by-Step Guide to Rekeying a Door Lock

Rekeying a standard door lock is a straightforward process if you have the right tools and instructions. Here’s how you can do it:

Necessary Tools and Materials:

  • A rekeying kit specific to your lock brand
  • Screwdriver
  • Needle-nose pliers
  • Tweezers


  1. Remove the Door Knob or Deadbolt: Start by removing the door knob or deadbolt from the door. You’ll typically need a screwdriver to do this.
  2. Take Out the Cylinder: Once the lock is removed, locate the cylinder and take it out of the lock housing.
  3. Remove the Cylinder Retainer Ring: Use the needle-nose pliers to remove the cylinder retainer ring carefully.
  4. Take Out the Cylinder Plug: Insert the old key and turn it slightly to align the pins. Use the plug follower (included in your rekeying kit) to carefully push the plug out of the cylinder.
  5. Insert New Keys and Pins: Replace the old pins with new ones provided in your rekeying kit to match the new key. Tweezers can be helpful in inserting the pins.
  6. Reassemble the Lock: Once the new pins are in place, reassemble the lock by following the disassembly steps in reverse.

Common Mistakes to Avoid:

  • Losing track of the order and orientation of components as you remove them.
  • Forcing parts together, which might cause damage.
  • Mixing up the new and old pins.
