Replacing the Battery in a Hyundai Key Fob
If you’ve noticed your Hyundai key fob isn’t working as well as it used to, or if you’re having to stand closer to your car to unlock it, it’s likely time for a new battery. This simple task can be done at home with minimal tools.
What Type of Battery Does a Hyundai Key Fob Use?
Most Hyundai key fobs use a CR2032 battery, a common type of button cell battery. You can find these batteries at most electronics stores, pharmacies, and online retailers. It’s always a good idea to keep a spare on hand.
Step-by-Step Guide to Changing Your Hyundai Key Fob Battery
Here’s a detailed, step-by-step guide on how to change a battery in a hyundai key fob:
- Locate the release button: Look for a small button or switch on your key fob. This is usually located on the side or back of the fob.
- Release the mechanical key: Press the release button and slide the mechanical key out of the fob. You’ll need this key to open the fob casing.
- Open the key fob casing: Use the tip of the mechanical key or a small flathead screwdriver to pry open the key fob casing along the seam. Be gentle to avoid damaging the plastic.
- Identify the battery: The battery is usually located in a small compartment inside the key fob. It’s a small, round, silver disc.
- Remove the old battery: Carefully pry the old battery out of its compartment using your fingernail, the mechanical key, or a small screwdriver. Take care not to damage the contacts within the battery compartment.
- Insert the new battery: Place the new CR2032 battery into the compartment, making sure the positive (+) side is facing up. The positive side is usually marked with a “+” symbol.
- Close the key fob casing: Snap the two halves of the key fob casing back together. Make sure it closes securely.
- Test the key fob: Try locking and unlocking your car with the key fob to make sure the new battery is working.
Troubleshooting Tips
If your Hyundai key fob still isn’t working after replacing the battery, try these troubleshooting steps:
- Check the battery orientation: Make sure the battery is inserted correctly with the positive (+) side facing up.
- Clean the battery contacts: Use a cotton swab dipped in rubbing alcohol to clean the battery contacts inside the key fob. This can help improve the connection between the battery and the fob.
- Try reprogramming the key fob: Consult your Hyundai owner’s manual for instructions on how to reprogram your key fob. Sometimes, the fob needs to be re-synchronized with your car after a battery change.
