Many 2004 Hyundai XG350 owners find themselves wondering about their key fob battery replacement options. This guide provides clear, step-by-step instructions to empower you to handle this task confidently. Before we dive into the how-to, let’s cover a few important basics.

What type of battery does a 2004 Hyundai XG350 key fob use?

The 2004 Hyundai XG350 key fob uses a CR2032 battery. This is a common lithium coin cell battery readily available at most electronics stores, pharmacies, and online retailers. It’s always a good idea to keep a spare on hand to avoid any unexpected lockouts.

What tools do I need to replace the key fob battery?

You’ll need a small flat-head screwdriver or a similar tool to pry open the key fob casing. Some key fobs have a small notch or slot specifically designed for this purpose. A small plastic opening tool, often included with replacement battery kits, can also be helpful to avoid scratching the key fob.

Step-by-Step Instructions

1. Locate the seam: Carefully examine your key fob and identify the seam or split line where the two halves of the casing join together. This is usually along the side of the fob.
2. Insert the screwdriver: Gently insert the flat-head screwdriver into the seam. Be careful not to force it, as this could damage the casing.
3. Pry open the casing: Use the screwdriver to carefully pry open the key fob casing. You may hear a slight clicking sound as the two halves separate.
4. Identify the battery: Once the casing is open, locate the CR2032 battery. It should be easily visible.
5. Remove the old battery: Gently pry out the old battery. You can use your screwdriver or the plastic opening tool for this step. Avoid touching the battery terminals.
6. Insert the new battery: Place the new CR2032 battery into the compartment, ensuring the positive (+) side is facing up, the same way the old battery was positioned.
7. Close the casing: Align the two halves of the key fob casing and press them firmly together until they snap shut.
8. Test the key fob: Try locking and unlocking your car to ensure the new battery is working correctly.
