Unlocking Your 2018 Hyundai Key Fob: A Step-by-Step Guide

There are several reasons you might need to open your 2018 Hyundai key fob. Perhaps the battery is dying and causing intermittent issues with locking or unlocking your car. Maybe you dropped it and suspect some internal damage. Whatever the reason, opening the key fob can seem daunting if you haven’t done it before. Don’t worry, it’s generally a simple process.

Locating the Release Button

Separating the Key Fob Halves

Once you’ve located the release, press it while gently pulling the two halves of the key fob apart. They should separate relatively easily. If you’re having trouble, try using a small flathead screwdriver or your fingernail to help pry them open. However, be cautious not to use excessive force, as you could damage the fob.

“A common mistake people make is using too much force when opening the key fob,” says automotive expert, Michael Carter. “This can break the plastic clips holding it together. Gentle pressure and a little patience are key.”
