Like any electronic device, your GMC key fob relies on a battery to function, and over time, this battery will need replacing. If you find your GMC key fob is becoming less responsive or completely dead, the most likely culprit is a low or dead battery. The good news is that changing the battery in your GMC key fob is a straightforward process you can easily do yourself. Most GMC key fobs use a common and readily available 3-volt CR2032 battery, designed to last for several years. This guide will walk you through the simple steps to replace your GMC key fob battery and get you back on the road quickly.
To change the battery in your GMC key fob, you will only need a couple of simple tools:
- A new CR2032 battery
- A small flathead screwdriver
Once you have gathered your tools, follow these steps to replace your GMC key fob battery:
Step 1: Open the Key Fob
Carefully inspect your GMC key fob to locate a small notch or seam. This is usually located on the side or bottom of the key fob. Insert the tip of your flathead screwdriver into this notch. Gently twist or pry to separate the two halves of the key fob casing. Be patient and avoid using excessive force to prevent damage to the plastic. The case should pop open relatively easily.
Step 2: Remove the Old Battery
With the key fob open, you will see the battery compartment. Take note of the orientation of the old battery before removing it. Specifically, observe whether the positive (+) side is facing up or down. This is crucial for correctly inserting the new battery. Typically, the positive side is facing upwards towards the back panel of the key fob. You can usually pry the old battery out gently with your fingertip or the flathead screwdriver if needed.
Step 3: Insert the New Battery
Take your new CR2032 battery and insert it into the battery compartment, ensuring that the polarity matches the orientation you noted when removing the old battery. In most cases, the positive (+) side of the new battery should face the same direction as the positive side of the old battery did. Push the battery firmly into place until it is securely seated in the compartment.
Step 4: Close the Key Fob
Carefully align the two halves of the GMC key fob casing. Press them firmly together until they snap back into place. Ensure that the case is completely closed and that there are no gaps.
In most instances, replacing the battery will restore full functionality to your GMC key fob. However, if you continue to experience issues after replacing the battery, there might be a more complex problem with your key fob or your vehicle’s receiver system. In such cases, it’s recommended to contact our dealership to schedule a service appointment.
