How to Change the Battery in a Hyundai Key Fob

A dead key fob battery can be a real pain, leaving you stranded and late for that important meeting. But don’t worry, changing the battery in your Hyundai key fob is a quick and easy process that you can do yourself in just a few minutes. This guide will walk you through the steps for a variety of Hyundai models, getting you back on the road in no time.

What You’ll Need:

A small flat-head screwdriver
A new CR2032 battery (often found at grocery stores, pharmacies, and auto parts stores)

Locating the Battery Compartment:

Most Hyundai key fobs have a separate battery compartment. You’ll find this on the back of the key fob, often indicated by a small groove.

Important Note: Some newer Hyundai models may have a different key fob design. If you can’t find a visible battery compartment, consult your owner’s manual for specific instructions.

Changing the Battery:

Open the Key Fob: Gently insert the flat-head screwdriver into the groove on the back of the key fob. Carefully pry open the two halves of the key fob. You might hear a slight click when it separates.
Remove the Old Battery: The CR2032 battery sits inside. Gently remove it, noting which side is facing up (positive (+) side usually faces up).
Insert the New Battery: Place the new CR2032 battery into the compartment, ensuring the positive (+) side matches the orientation of the old battery.
Reassemble the Key Fob: Align the two halves of the key fob and press them firmly together until you hear a click, indicating they’re securely closed.

Testing Your Key Fob:

Try locking and unlocking your car using the key fob buttons. If it doesn’t work, double-check that the battery is correctly installed and that the contacts inside the key fob are clean.

Tips and Tricks:

Avoid Touching the Battery Contacts: The oils on your fingers can corrode the battery contacts and affect performance. If you do touch them accidentally, clean them with a dry cloth.
Dispose of the Old Battery Properly: CR2032 batteries contain lithium and should be disposed of responsibly. Check with your local recycling center for proper battery disposal options.
