• Key Battery Low Warning: Your vehicle’s instrument cluster displays a “key battery low” warning.
• Remote Functions Don’t Work: If your key’s remote functions completely stop working, it’s a sure sign that the battery needs replacing.

Gathering Your Supplies

Before you embark on your key battery replacement journey, ensure you have the following materials:

• A new CR2032 battery: This is the standard battery size used in most Hyundai Santa Fe key fobs.
• A small Phillips screwdriver: You’ll need this to open the key fob.
• A small, flat-head screwdriver (optional): This can be helpful for prying open stubborn key fobs.

Troubleshooting Common Issues

While replacing the battery is usually straightforward, there are a few common issues that you might encounter:
