Is your 2020 GMC Acadia key fob not working as reliably as it used to? Before you worry about complicated issues, the solution might be as simple as replacing the battery. The most common culprit for a malfunctioning key fob is a dead battery. Luckily, changing the battery in your GMC Acadia key fob is a straightforward process you can easily do yourself.
Identifying a Dead Key Fob Battery
Key fobs for the 2020 GMC Acadia, like many modern car keys, are powered by small batteries. Typically, these fobs use a CR2032 3-volt battery. These batteries are designed to last for several years, usually three to four, but various factors can shorten their lifespan. If you notice your key fob is becoming less responsive, or if it only works when you are very close to your Acadia, a low or dead battery is likely the cause.
What You’ll Need
Replacing your 2020 Gmc Acadia Key Fob Battery requires just a couple of simple tools:
- A new CR2032 battery: You can find these batteries at most drug stores, supermarkets, hardware stores, and online retailers. Consider keeping a spare on hand.
- A flathead screwdriver: A small, flathead screwdriver will help you to open the key fob casing.
Step-by-Step Battery Replacement
Here’s how to replace the battery in your 2020 GMC Acadia key fob:
Step 1: Open the Key Fob
Locate the small seam on your GMC Acadia key fob. Gently insert the flathead screwdriver into this seam. Carefully twist or pry to separate the two halves of the key fob. Avoid using excessive force to prevent damage to the casing.
Step 2: Battery Removal and Replacement
Once the key fob is open, you’ll see the CR2032 battery. Take note of the battery’s orientation – specifically, which side is facing up. Typically, the positive (+) side faces outwards. Carefully remove the old battery. Install the new CR2032 battery, ensuring the positive side is facing in the correct direction, just as the old battery was positioned.
Step 3: Closing the Key Fob
After inserting the new battery, carefully align the two halves of the key fob casing. Press them firmly together until they snap securely back into place. Ensure there are no gaps and the fob feels properly closed.
When to Seek Professional Help
In most cases, replacing the battery will solve the issue with your 2020 GMC Acadia key fob. However, if you’ve replaced the battery and your key fob is still not functioning correctly, there might be a more complex problem. This could involve issues with the key fob itself or your vehicle’s receiver system. If you continue to experience problems after a battery replacement, it’s recommended to contact a certified mechanic or your local GMC dealership for further diagnosis and repair. They can accurately determine if there are any underlying electronic issues or if the key fob itself needs attention.
