2018 Buick Encore Key Fob Battery Replacement: A Quick Guide

Experiencing a finicky key fob with your 2018 Buick Encore? It might be time for a quick battery replacement. Don’t fret! This guide will walk you through the process, equipping you with the knowledge to tackle this simple task yourself and save a trip to the dealership.

Identifying a Dying Key Fob Battery

Before diving into the replacement, let’s ensure a dying battery is the culprit. Look out for these telltale signs:

• Decreased Remote Range: Is your Encore only responding to the key fob from uncharacteristically close distances?
• Inconsistent Locking/Unlocking: Does it take multiple button presses to lock or unlock your car?
• Dashboard Warning Light: Some Buick Encores may display a “Key Fob Battery Low” warning on the dashboard.

If you’re nodding along, a battery swap is likely the solution.

Gathering Your Tools

Good news: you won’t need a mechanic’s tool kit for this task! All you need is:

• A new CR2032 battery: Easily found at most grocery stores, pharmacies, and auto parts shops.
• A small flat-head screwdriver: This will help with gently prying open the key fob.

Replacing the Battery: A Step-by-Step Guide

1. Locate the release button: On the back of your Buick Encore key fob, you’ll find a small, often indented, release button.
2. Open the key fob: Press the release button and gently separate the two halves of the key fob. You might need to use the flat-head screwdriver to carefully pry them apart.
3. Access the battery: Inside, you’ll see the CR2032 battery nestled in its compartment.
4. Remove and replace: Carefully remove the old battery and replace it with the new one, ensuring the positive (+) side faces up.
5. Reassemble the key fob: Align the two halves of the key fob and press them back together until you hear a click, indicating they’re securely closed.

Testing Your New Battery

Once assembled, test if the replacement was successful by trying to lock and unlock your Buick Encore using the key fob. If it’s working from a reasonable distance, congratulations! You’ve successfully replaced your key fob battery.

Still Having Trouble?

If your key fob is still acting up after a battery replacement, don’t despair. There could be other issues at play, such as:

• Key Fob Programming: Your key fob might need to be reprogrammed to your Buick Encore.
• Faulty key fob: In some cases, the key fob itself may be damaged and require replacement.

For these issues, consider reaching out to a qualified automotive locksmith or your Buick dealership for assistance.
