Recognizing the Signs of a Dying Key Fob Battery
Before you start digging for a new battery, it’s important to recognize the telltale signs of a dying key fob. These include:
- Reduced key fob range: You might find yourself having to stand closer to your car to lock or unlock it.
- Intermittent key fob function: The key fob might work sometimes and not others, or require multiple button presses.
- Dim or non-existent key fob light: The indicator light on your key fob might be fainter than usual, or not light up at all.
If you’re experiencing any of these issues, it’s likely time for a new key fob battery.
How to Replace Your Buick Key Fob Battery
Replacing the battery is a straightforward process, usually requiring only a small flathead screwdriver and a new battery (typically a CR2032). Here’s a step-by-step guide:
-
Locate the release button or slot on your key fob. This is usually a small button or indentation on the side or back of the fob.
-
Insert the flathead screwdriver into the release button or slot and gently pry open the key fob casing. Be careful not to damage the casing.
-
Identify the old battery. It’s typically a small, round, silver battery labeled CR2032.
