Is your 2019 GMC Terrain key fob not working? Don’t worry, you’re not alone. One of the most common culprits for a dead key fob is a simple battery issue. The good news is that replacing the battery in your GMC Terrain key fob is a straightforward process you can easily do yourself. This guide will walk you through everything you need to know about changing the battery in your 2019 GMC Terrain key fob, ensuring you’re back on the road quickly.
Most GMC Terrain key fobs, including those for the 2019 model, use a CR2032 3-volt battery. These batteries are known for their longevity, typically lasting between three to four years under normal use. However, factors like frequency of use and environmental conditions can affect battery life. When your key fob starts to become unresponsive or only works intermittently, it’s usually a sign that the battery is nearing the end of its life and needs replacement.
Replacing the battery in your 2019 GMC Terrain key fob is a simple DIY task that requires minimal tools. Here’s what you’ll need:
- A new CR2032 battery: You can purchase these at most drugstores, supermarkets, hardware stores, and online retailers. Consider buying name brands for potentially longer life.
- A small flathead screwdriver: This will be used to gently pry open the key fob casing.
Once you have your tools and replacement battery ready, follow these step-by-step instructions to change the battery in your 2019 GMC Terrain key fob:
- Locate the small notch: On your GMC Terrain key fob, you’ll find a small notch, usually located on the side or bottom of the fob. This is where you’ll insert the flathead screwdriver.
- Carefully pry open the casing: Gently insert the tip of your flathead screwdriver into the notch. Apply slight pressure and twist gently to separate the two halves of the key fob casing. Avoid using excessive force, as you could damage the plastic. The case should pop open with minimal effort.
- Identify the battery: Once the key fob is open, you will see the CR2032 battery. Take note of the battery orientation – specifically, how the positive (+) side is facing. Usually, the positive side is facing upwards or towards the back cover of the fob. This is important to ensure you insert the new battery correctly.
- Remove the old battery: Carefully remove the old battery. You can often use your fingernail or the edge of the screwdriver to gently lift it out of its compartment.
- Insert the new battery: Place the new CR2032 battery into the compartment, ensuring the positive (+) side is facing the same direction as the old battery was.
- Reassemble the key fob: Align the two halves of the key fob casing and gently snap them back together. You should hear a click, indicating that they are securely closed.
After replacing the battery, your 2019 GMC Terrain key fob should work perfectly. Test all the buttons to ensure proper functionality, including locking, unlocking, remote start, and panic button (if applicable).
In the vast majority of cases, replacing the battery will solve the issue of a non-working key fob. However, if you have replaced the battery and your 2019 GMC Terrain key fob is still not functioning, there might be a more complex issue. This could involve problems 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 GMC service center or your local GMC dealership. They have the expertise and equipment to diagnose and resolve more intricate key fob and vehicle electronic issues. You can also contact our dealership to schedule an appointment with our service department for professional assistance.
