How to Change Battery in Car Key Fob Hyundai? A Step By Step Guide

Are you experiencing issues with your Hyundai car key fob? Does it fail to respond to your commands, or does it require multiple presses to unlock your vehicle? If yes, it’s likely that the battery in your key fob is running out of power. In this comprehensive guide, we will walk you through the step-by-step process of changing the battery in your Hyundai car key fob. This is an essential skill to learn, as it will save you time and money in the long run. Moreover, it’s a simple process that can be done at home with basic tools, making it a cost-effective solution.

Before we dive into the process, let’s understand the importance of a functioning car key fob. A car key fob is a small device that contains a battery, a microcontroller, and a radio frequency (RF) transmitter. The RF transmitter sends a signal to your vehicle’s receiver, which then unlocks or locks the doors, starts the engine, and performs other functions. If the battery in your key fob is dead, the device will not function properly, and you may experience issues with your vehicle’s security system.

Changing the battery in your Hyundai car key fob is a relatively simple process that requires minimal tools and expertise. However, it’s essential to follow the correct procedure to avoid damaging the device or compromising its security features. In this guide, we will cover the following topics:

Preparation and Safety Precautions

Before starting the process, make sure you have the following tools and materials:

• A new battery (CR2032 or CR2016, depending on the type of key fob you have)
• A screwdriver (preferably a small flathead screwdriver)
• A plastic spudger or a similar tool for prying open the key fob
• A cloth or a soft brush for cleaning the key fob’s interior

It’s also essential to take some safety precautions before starting the process:

• Make sure you have a spare key or a backup key fob in case the new battery doesn’t work.
• Remove any metal objects from your key fob, as they may interfere with the new battery.
• Ground yourself by touching a metal object or wearing an anti-static wrist strap to prevent static electricity from damaging the key fob’s electronics.

Opening the Key Fob

To open the key fob, you’ll need to pry it open using a plastic spudger or a similar tool. Start by inserting the spudger into the small gap between the key fob’s casing and the internal components. Gently pry the casing open, taking care not to damage the internal components or the key fob’s electronics.

Once you’ve opened the key fob, you’ll see the battery compartment located on the back of the device. The compartment is usually secured with a small screw or a clip. Remove the screw or clip using a small flathead screwdriver. (See Also: How to Attach Trickle Charger to Car Battery? Easy Steps)

Removing the Old Battery

Locate the old battery and carefully remove it from the compartment. Take note of the orientation of the battery, as you’ll need to install the new battery in the same orientation.

Use a cloth or a soft brush to clean the battery compartment and remove any debris or corrosion. This will ensure a clean and secure connection between the new battery and the key fob’s electronics.

Installing the New Battery

Take the new battery and insert it into the compartment, making sure it’s aligned with the correct orientation. Secure the battery in place using the screw or clip you removed earlier.

Make sure the battery is properly seated and the compartment is closed securely. If you’re using a screw, tighten it firmly but avoid over-tightening, which may damage the key fob’s electronics.

Testing the Key Fob

Once you’ve installed the new battery, close the key fob and test it by pressing the buttons. Make sure the key fob is responding properly and performing its functions correctly.

If the key fob is not working, check the following:

• The battery is properly seated and the compartment is closed securely.
