Low battery car keys can be frustrating, but they’re an easy fix! Follow these steps to change the battery in your Hyundai key:
Remove the spare physical key by depressing the metal tab on the back of your key. Use the key to pop the plastic fob casing open by twisting it in the hole that it’s inserted into.
Once the casing is open, carefully remove the circuit board to reveal the battery on the other side.
Remove the old battery and pop in the new one—you can find out which one you need in your owner’s manual. Make sure the new battery is inserted with the negative side facing up.
Place the circuit board back in place, snap the plastic casing shut, and reinsert the metal key.
