How to Change the Code on an Electronic Door Lock

Published: Sep 8, 2022

Changing the code on your electronic door lock may feel challenging, especially if you’ve never done it before. However, understanding the process is simpler than you might think. It’s an important step in keeping your home secure, and Sure Lock & Key is here to help!

Whether you’re resetting the code for privacy reasons, moving into a new house, or updating the door with a new device, this guide will help you understand the entire process. From the tools you need to a detailed step-by-step guide, we’ll explain everything so you can get the job done safely and effectively.

Resetting the Code Yourself vs. Calling a Professional

One of the first choices you’ll need to make is whether to reset the code yourself or call in a professional locksmith. Both options have their advantages, depending on your experience, the type of lock, and how complex the task is.

Let’s take a closer look:

DIY: When You Can Do It Yourself

If your lock has a simple reset process, including entering a code via the keypad, handling it on your own is often manageable. Many electronic locks include clear manuals or even video tutorials to walk you through the process step by step.

Here’s what to consider before taking the DIY route:

DIY is best for simpler keypad locks or ones you’re already familiar with.
You’ll need the right tools, some patience, and a basic understanding of how your lock functions.
While resetting your lock code yourself can save time and money, it’s important to be confident in your abilities to avoid mistakes.

When It's Time to Call a Locksmith

Calling a professional is usually the safer choice, especially for complex systems. A trained locksmith can ensure the job is done properly, reducing the chance of damaging your lock or voiding a warranty.

Consider professional help if:

You don’t know your lock’s model or don’t have access to its manual.
The lock is old or shows signs of wear and tear, which could make resetting challenging.

You want expert guidance on choosing a stronger, more secure code for your home.
Whether you choose to DIY or hire a locksmith, the most important thing is ensuring your home remains secure and your lock functions properly.

Tools You’ll Need to Change the Code

Before you start, gather the tools you’ll need to keep the process smooth and safe. The right equipment will make the job easier and help protect your lock from damage.

Here’s what you’ll need:

Screwdriver: Depending on your lock type, you’ll need either a Phillips or flathead screwdriver to remove the screws.
Tweezers: This tool is essential for locks that use code chips to set or update the code.
User Manual: If you have one, it will provide specific instructions for your lock model.
Soft Cloth: Use a soft cloth to protect delicate parts and prevent scratches during the process.

These tools are easy to find. If you’re missing anything, a quick trip to the hardware store will fix the problem.

Step-by-Step Guide to Resetting the Code

Now that you’re ready, let’s go through the process together. Follow this simple, step-by-step guide on how to reset your lock’s code with ease:

Step 1: Understand Your Door Lock Model

Knowing your lock’s model is essential to follow the correct steps and avoid mistakes. Check the manual or search online for model-specific details to be sure you’re on the right track.

Step 2: Remove the Lock from the Door

Use a screwdriver to unscrew the lock from the door. Most locks are held in place with two screws on the interior side. Be careful to avoid stripping the screws or damaging the door.

Step 3: Detach the Back Cover

Flip the lock so the keypad faces down. Unscrew the back cover, which is usually secured by two or more screws. Place the cover and screws in a safe spot to avoid losing them.

Step 4: Identify and Remove the Old Code

For locks with code chips, locate the red chips inside the mechanism, as they represent the current code. Carefully remove them with tweezers and set them aside.

Step 5: Insert the New Code

Choose your new code and insert red chips into the holes that match your selected numbers. For keypad locks, use the manual’s instructions to program the new code.

Step 6: Reassemble and Test

Reattach the back cover and secure it with screws. Mount the lock back onto the door, ensuring it’s properly aligned. Test the new code several times to make sure it works properly.

Overcoming Challenges in Lock Code Updates

Even when you’re well-prepared, things don’t always go as smoothly as planned. If the new code isn’t working, a chip might be out of place, or the keypad sequence may need re-entering. If the lock won’t go into programming mode, a battery replacement could solve the problem. However, when the lock feels stuck or unresponsive, it could indicate a mechanical problem.

In these situations, calling a professional locksmith is the best decision. They can quickly identify the issue, fix it safely, and make sure your lock functions properly.

Summing up

In summary, knowing how to change the code on your electronic lock is a valuable skill. Whether you’re setting up a code for house guests or updating it to increase security, resetting locks is always a smart move.
