2021 Buick Encore Key Fob Battery Replacement: A Quick Guide

Having trouble with your 2021 Buick Encore key fob? Before you schedule a trip to the dealership, it might be a simple battery issue. This guide will walk you through the process of changing your Buick Encore key fob battery like a pro.

Is it Really the Battery?

Key fobs can act up for several reasons, but a dying battery is often the culprit. Here are a few telltale signs that your key fob battery needs replacing:

  • Decreased Range: Are you noticing that your key fob only works when you’re standing right next to your Encore? That’s a classic sign of a fading battery.
  • Intermittent Functioning: If your Encore sometimes responds to your key fob and sometimes doesn’t, that’s another clue that the battery is on its way out.
  • Warning Messages: Some Buick Encores might display a warning message on the dashboard, like “Key Fob Battery Low,” when it’s time for a replacement.

What You’ll Need

  • New Battery: You’ll need a CR2032 battery. These are readily available at most drugstores, supermarkets, and online retailers.
  • Small Flathead Screwdriver: This will be used to open the key fob.

Let’s Replace That Battery!

  1. Locate the Release Button: On the back of your Buick Encore key fob, you’ll see a small button.
  2. Release the Key Blade: Press the release button and gently slide the metal key blade out of the fob.
  3. Open the Fob: Use the flathead screwdriver to carefully pry open the fob casing. There’s usually a small notch where you can insert the screwdriver.
  4. Remove the Old Battery: The CR2032 battery will be easily visible. Gently pry it out using the screwdriver or your fingernail.
  5. Insert the New Battery: Make sure the positive (+) side of the new battery is facing up, just like the old one.
  6. Close the Fob: Align the two halves of the key fob and press them firmly together until you hear a click.
  7. Reinsert the Key Blade: Slide the key blade back into the fob until it locks in place.

Testing, Testing

Once the key fob is back together, try locking and unlocking your Buick Encore a few times to make sure everything is working properly.

“Regularly inspecting and replacing your key fob battery can prevent those frustrating moments when you’re in a hurry and your car won’t respond,” advises John Davis, Senior Automotive Technician at CarDiagTech Workshop. “It’s a simple DIY task that can save you time and potential headaches down the road.”
