If your Hyundai Sonata key fob blinks but doesn’t open the car, there might be an issue with the key fob battery. Common reasons for this issue include a dead battery, a faulty key fob, or a problem with the car’s receiver.

Understanding Your Hyundai Key Fob

Hyundai key fobs, like those used for the 2021 Hyundai Elantra key fob buttons, come in a variety of designs depending on the model and year of your car. Some have a visible slot for a key release button, while others require a bit more finesse. It’s crucial to identify your specific key fob type before attempting to open it. This will help you avoid applying unnecessary force which could damage the internal components. You can usually find diagrams and instructions in your car’s owner’s manual or by searching online for your specific Hyundai model.

How to Open Your Hyundai Car Key Fob: A Step-by-Step Guide

Locate the Key Release: Examine your key fob for a small button or switch often located on the side or back. This is the key release button. If you don’t see a readily accessible button, your key fob might have a hidden release mechanism.
Release the Emergency Key: Press the key release button and gently slide the metal emergency key out of the fob. This key is useful for unlocking your car door manually if the key fob battery dies. You may need this key to help pry open the key fob casing.
Identify the Seam: Look closely at the edges of the key fob casing. You’ll notice a thin seam where the two halves of the casing meet. This is where you’ll need to apply gentle pressure to separate the halves.
Separate the Halves: Carefully insert the tip of the emergency key or a small flat-head screwdriver into the seam. Gently twist or pry to separate the two halves of the key fob. Avoid using excessive force, as this can damage the casing. Some key fobs, like the one detailed in the article about how to change battery on 2017 hyundai sonata key fob, have specific opening procedures.
Access the Battery: Once the key fob is open, you should be able to see the battery. Note the battery type and orientation for replacement.
