A dead key fob can be a real pain, especially when you’re trying to get somewhere in a hurry. Knowing how to perform a Hyundai key fob battery change can save you time, money, and a lot of frustration. This guide will walk you through the simple process of replacing your Hyundai key fob battery, covering various models and providing expert tips for a smooth experience.
Identifying Your Hyundai Key Fob Type
Before diving into the Hyundai key fob battery change process, it’s crucial to identify your key fob type. Different Hyundai models use slightly different key fobs, and understanding your specific type will ensure you follow the correct procedure. Generally, Hyundai key fobs can be categorized into two main types: the traditional flip key and the smart key/proximity key.
Flip Key Fob Battery Replacement
The flip key, a classic design, has a physical key blade that folds out from the fob. To access the battery compartment, locate the small release button or notch on the fob. Gently press this button or use a small flathead screwdriver in the notch to separate the two halves of the fob. Inside, you’ll find the battery, typically a CR2032.
Smart Key/Proximity Key Fob Battery Replacement
Smart keys, also known as proximity keys, offer keyless entry and push-button start. These fobs usually have a small emergency key blade hidden within. To access the battery compartment, you’ll typically find a small release button or slot on the side or back of the fob. Pressing this button or inserting a small flathead screwdriver into the slot will release the emergency key blade. The battery compartment is often located behind the key blade, commonly using a CR2032 battery.
