How to Replace the Battery in Your Buick Regal Key Fob (2018-2020)

Introduction

In this guide, I will walk you through the process of changing the battery in your Buick Regal key fob. Whether your key fob has three, four, or five buttons, the process remains the same. By following these steps, you’ll save time and money by avoiding a trip to the dealership.

What You Will Need

To replace the battery in your Buick Regal key fob, you will need only one item:

• CR2032 battery

You can purchase a CR2032 battery online. I recommend getting it from Amazon for convenience.

Step-by-Step Instructions

Let’s dive into the step-by-step process to replace the key fob battery.

Step 1: Remove the Internal Key

First, flip the key fob over to locate a small silver button. Hold this button down while pulling the internal key out. This key will be used to open the device.

Step 2: Pry Open the Key Fob

Insert the key back into the slot, but only slightly. You don’t want to insert it too far. The goal is to pry open the back section of the plastic casing.

Put the key in about a quarter of an inch and gently pry back. The back section of the plastic should click open, giving you access to the battery inside.

Step 3: Remove the Old Battery

Once the key fob is open, you will see the battery. You can try to pull it out with your fingernail, but if that doesn’t work, use a flathead screwdriver, pen, or pencil to lift the battery out.

Step 4: Insert the New Battery

Take your new CR2032 battery and ensure the positive side is facing down. Click the new battery into place.

If you need to purchase a new battery, you can get one from Amazon.

Step 5: Reassemble the Key Fob

Now that the new battery is in place, click the back section of the plastic casing back together. Finally, insert the internal key back into its slot.

Conclusion

And there you have it! You’ve successfully replaced the battery in your Buick Regal key fob. This simple process can save you both time and money. If you found this guide helpful, feel free to share it with others or leave a comment below.
