Is your 2018 GMC Acadia key fob not working as reliably as it used to? You might be experiencing the most common culprit behind key fob issues: a dead battery. Like most modern key fobs, the one for your 2018 GMC Acadia relies on a small, replaceable battery to function. The good news is that changing it is a straightforward process you can easily handle yourself.
Typically, GMC Acadia key fobs use a CR2032 3-volt battery. These batteries are designed to last for several years, usually between three to four, depending on usage. However, when the battery starts to weaken, you’ll notice a decrease in your key fob’s range and responsiveness. Fortunately, replacing the battery in your 2018 GMC Acadia key fob is a quick and inexpensive fix.
Here’s what you’ll need to replace your 2018 Gmc Acadia Key Fob Battery:
- A new CR2032 battery
- A small flathead screwdriver
Once you have these items, follow these simple steps:
-
Locate the notch to open the Fob: Examine your 2018 GMC Acadia key fob. You’ll find a small notch, usually on the side or bottom of the fob. This is where you’ll insert the flathead screwdriver to gently pry it open.
-
Carefully Pry Open the Key Fob: Insert the tip of your flathead screwdriver into the notch. Gently twist the screwdriver to separate the two halves of the key fob. Avoid using excessive force to prevent damaging the casing. The key fob should pop open with minimal effort.
-
Remove the Old Battery: With the key fob open, you’ll see the CR2032 battery. Take note of the battery orientation – specifically, which side is facing up (positive or negative). This is crucial for correct installation of the new battery. You can usually gently pry the old battery out with your fingertip or the flathead screwdriver if needed.
-
Insert the New Battery: Place the new CR2032 battery into the battery compartment, ensuring the correct polarity matches the orientation you noted earlier. Typically, the positive (+) side of the battery faces upwards or towards the back cover of the fob.
-
Reassemble the Key Fob: Carefully align the two halves of the 2018 GMC Acadia key fob and snap them back together. You should hear a click, indicating that the fob is securely closed.
After replacing the battery, your 2018 GMC Acadia key fob should be working perfectly again.
