Key Fob Overview
Your Hyundai Santa Fe key fob uses a CR2032 battery. It locks, unlocks, starts your vehicle remotely, and has a panic button.
- Locking: Keeps your car secure.
- Remote Start: Convenient for extreme weather.

Fresh batteries ensure good performance. A weak battery can reduce the signal range. If buttons stop responding, it’s time to replace the battery.

Identifying the Battery Type
To identify the correct battery type for your Hyundai Santa Fe key fob, look for specifications like size and voltage, typically found in your owner’s manual or on the existing battery.
