If you own a 2012 Hyundai Sonata, chances are you’ve experienced the inconvenience of a dying key fob battery. Don’t worry, replacing the battery in your 2012 Hyundai Sonata key fob is a quick and easy process that you can do yourself, saving you a trip to the dealership. This comprehensive guide will walk you through each step, ensuring you get back to enjoying the convenience of your keyless entry system in no time.
Understanding Your Hyundai Sonata Key Fob
Before you begin, it’s helpful to understand the two main types of key fobs that come with the 2012 Hyundai Sonata:
- Standard Key Fob: This fob has lock, unlock, and trunk release buttons. It’s commonly used for vehicles without a push-button start.
- Proximity Key Fob: Also known as a “smart key,” this fob allows you to unlock your car and start the engine without ever taking the key out of your pocket or purse.
The battery replacement process is similar for both types. This guide will focus on the standard key fob, but the steps can be easily adapted for the proximity key fob as well.
What You’ll Need

- A small flat-head screwdriver: You’ll use this to open the key fob.
Step-by-Step Guide to Replacing Your Key Fob Battery
- Locate the release button: On the back of your key fob, you’ll find a small release button. It might be located near the key ring.
- Open the key fob: Press the release button and gently separate the two halves of the key fob. You might need to use a bit of pressure.
- Identify the battery: Inside, you’ll see the CR2032 battery.
- Remove the old battery: Carefully pry out the old battery using the flat-head screwdriver. Be careful not to damage the contacts inside the key fob.
