Why is My GM Key Fob Not Working?
A dead battery is the most common reason for a malfunctioning key fob. Signs of a dying battery include decreased range, intermittent operation, and the need to press buttons multiple times. Other less common issues, such as a faulty key fob or a problem with the vehicle’s receiver, can also cause problems. However, starting with a battery replacement is usually the simplest and most effective first step in troubleshooting.
What Type of Battery Does a GM Key Fob Use?
Most GM key fobs utilize a CR2032 3-volt lithium coin battery. These batteries are readily available at most electronics stores, pharmacies, and online retailers. While some older GM models may use different batteries, the CR2032 is the most prevalent. Before purchasing a replacement, it’s always a good idea to check your owner’s manual or the existing battery in your key fob to confirm the correct type.
