Changing the battery in your Hyundai key fob is a simple task that can save you time and money. A dying key fob battery can manifest as reduced range, intermittent functionality, or a complete failure to unlock or start your car. This guide will walk you through the process for various Hyundai models, ensuring you’re back on the road with minimal hassle.
Identifying Your Hyundai Key Fob Type
Hyundai offers several key fob designs. Identifying your specific type will help determine the exact battery replacement procedure. Some common types include the standard flip key, the smart key, and the proximity key. Each uses a similar battery, but access to the battery compartment may differ. Do you have a flip key, a smart key, or a proximity key? Knowing this will make the process smoother.
Flip Key Battery Replacement
The flip key is the most traditional design. To change the battery:
- Locate the small release button on the fob. This is often near the key ring.
- Press the release button and gently separate the metal key from the fob.
- Use a small flathead screwdriver or a similar tool to pry open the fob casing. Be careful not to damage the plastic.
- Identify the battery type (usually a CR2032).
- Remove the old battery and replace it with a new one, ensuring the positive (+) side faces up.
- Snap the fob casing back together and reattach the metal key.
Smart Key Battery Replacement
Smart keys usually have a hidden key blade for emergency access. To access the battery:
- Locate the small release button or switch that releases the emergency key blade.
- Once the key blade is released, use it or a small flathead screwdriver to pry open the fob casing along the seam.
- Locate the battery (typically a CR2032) and replace it, paying attention to the positive (+) side.
- Reassemble the fob.
