Is your GMC Sierra key fob not working? Before you panic, the most likely culprit is a dead battery. Fortunately, replacing the battery in your GMC Sierra key fob is a quick and easy task you can do yourself, saving you time and a trip to the dealership. Most GMC Sierra key fobs use a common 3-volt CR2032 battery, known for its long life, typically lasting three to four years. When the time comes for a replacement, you’ll be pleased to know it’s a straightforward process requiring minimal tools. This guide will walk you through each step to replace your GMC Sierra key fob battery and get you back on the road with a working remote.
What You’ll Need to Replace Your Key Fob Battery
Before you begin, gather these simple tools:
- A new CR2032 battery: These batteries are widely available at most drugstores, grocery stores, hardware stores, and online retailers. Consider buying a multi-pack to have spares on hand.
- A small flathead screwdriver: This will be used to gently pry open the key fob casing.
Step-by-Step Guide to Replacing Your GMC Sierra Key Fob Battery
Follow these easy steps to replace your GMC Sierra key fob battery:
Step 1: Open the Key Fob Casing
Locate the small notch on your GMC Sierra key fob. This notch is usually found on the side or bottom of the fob, depending on your model. Carefully insert the tip of your flathead screwdriver into this notch. Gently twist or pry to separate the two halves of the key fob casing. Avoid using excessive force, as you could damage the plastic. The casing should pop open with a little bit of pressure.
Step 2: Remove the Old Battery and Install the New One
Once the key fob is open, you will see the battery compartment. Take note of the orientation of the old battery – specifically, which side is facing up (+ positive or – negative). This is important to ensure you install the new battery correctly. Typically, the positive (+) side faces upwards or towards the back cover of the key fob. Carefully remove the old battery. You may be able to gently pry it out with your fingertip or the edge of the screwdriver if needed. Insert the new CR2032 battery into the compartment, making sure the positive (+) side is facing the same direction as the old battery was removed.
Step 3: Close the Key Fob Casing
With the new battery securely in place, carefully align the two halves of the GMC Sierra key fob casing. Press them firmly together until they snap back into place. You should hear a click indicating that the casing is properly closed and secure.
Test Your Key Fob
After reassembling your key fob, test it to ensure it is working correctly. Try locking and unlocking your GMC Sierra, and if applicable, test the remote start and panic buttons. In most cases, replacing the battery will solve the problem, and your key fob will be functioning like new.
What If Your GMC Sierra Key Fob Still Doesn’t Work?
If you’ve replaced the battery and your GMC Sierra key fob is still not working, there might be another issue. It’s possible there’s a problem with the key fob itself or your vehicle’s receiver system. In such cases, it’s best to contact our dealership to schedule a service appointment. Our certified technicians can diagnose the problem and recommend the necessary repairs, whether it’s further key fob troubleshooting or addressing a vehicle-related electronic issue.
