How to Change Battery in Hyundai Key Fob 2020

Knowing how to change the battery in your 2020 Hyundai key fob is a simple skill that can save you time and money. A dead key fob battery can leave you stranded, so understanding this quick process is essential for every Hyundai owner. This guide will walk you through the steps involved in replacing the battery in your 2020 Hyundai key fob, ensuring you’re never caught off guard.

Locating the Release Button and Key Fob Components

The first step in changing your 2020 Hyundai key fob battery is locating the small release button. This button is usually found on the side or back of the key fob. It might be slightly recessed or hidden, so look carefully. Once you find the release button, use a small flathead screwdriver or a similar tool to gently press it. This will allow you to separate the key fob’s physical key from the main fob body. The physical key is important as it acts as a lever in the next step.

Opening the Key Fob and Identifying the Battery

Once the physical key is detached, you can use it to pry open the key fob casing. Locate a small slot or notch on the key fob’s edge. This is where you’ll insert the tip of the physical key. Gently twist the key to separate the two halves of the key fob casing. Be careful not to apply excessive force, as this could damage the plastic. Inside, you’ll see the battery. Note the type of battery used – it’s typically a CR2032 3V lithium battery. This is a common battery type and readily available at most stores.

Replacing the Battery and Reassembling the Key Fob

With the old battery identified, gently remove it. You can use your fingernail or a small flathead screwdriver to carefully pry it out. Avoid puncturing or damaging the battery. Once the old battery is removed, insert the new CR2032 battery, making sure the positive (+) side is facing upwards, just like the old battery. Once the new battery is securely in place, align the two halves of the key fob casing and press them together until they snap shut. Finally, reattach the physical key to the fob.

Testing the New Battery

After reassembling the key fob, test all its functions to ensure the new battery is working correctly. Try locking and unlocking your car’s doors and starting the engine. If everything works as expected, you’ve successfully changed your Hyundai key fob battery!
