If you’re driving a 2006 Hyundai Elantra, chances are you’ve experienced the convenience and reliability of its key fob system. But like any electronic device, the battery in your key fob won’t last forever. Luckily, replacing it is a quick and easy fix you can often handle yourself. Let’s walk through everything you need to know about 2006 Hyundai Elantra Key Fob Battery Replacement.
Recognizing a Dying Key Fob Battery
Before you start digging for tools, it’s good to be sure that a dying battery is actually the culprit. Here are a few telltale signs:
- Decreased Range: Is your car only responding to the key fob at very close range? That’s a classic sign your battery is losing juice.
- Intermittent Functioning: If your car unlocks and locks sporadically, even when you’re sure you’re pressing the right buttons, blame the battery.
- Warning Lights and Sounds: Some Hyundai Elantras might flash warning lights on the dashboard or beep repeatedly when the key fob battery is critically low.
What You’ll Need for the Replacement
Don’t worry, you won’t need a mechanic’s toolkit for this job! Here’s what you’ll need:
- A fresh CR2032 battery: These are commonly available at supermarkets, electronics stores, and online.
- A small flat-head screwdriver: This will help you pry open the key fob casing.

- Remove the physical key: Slide the key out of the fob.
- Gently pry open the fob: Insert the flat-head screwdriver into the seam of the key fob casing and carefully pry it open.
- Remove the old battery: Take note of how the old battery is positioned – the “+” side usually faces up.
