Here are the steps to follow:

Step 1: Enter your vehicle and close all the doors

Make sure that all the windows and doors are closed before you start the programming process.

This will ensure that the key fob can communicate with your vehicle’s system without any interference.

Step 2: Turn the key to the ACC position

Insert the key into the ignition and turn it to the ACC position, which is the first notch on the ignition. Do not start the engine or turn the key to the ON position.

The ACC position will activate the accessory functions of your vehicle, such as the radio and the dashboard lights.

Step 3: Hold down the unlock button on the key fob

Locate the unlock button on your key fob, which is usually marked with an open padlock symbol or the word “open”.

Press and hold down this button for several seconds until you see your vehicle’s lights flash.

This indicates that the key fob has been programmed to your vehicle.

Step 4: Test the key fob functions

Release the unlock button and remove the key from the ignition.

You can now test the key fob functions, such as locking and unlocking the doors, opening the trunk, or activating the alarm system.

If everything works properly, you have successfully programmed your Hyundai key fob yourself.

Tips and Warnings

1.Some Hyundai models may require different steps or additional steps to program the key fob. You can check your owner’s manual or contact your dealer for more information.

3.If you lose your original key fob or it is damaged beyond repair, you will need to get a new one from a dealer or a locksmith. You will also need to provide proof of ownership and identification to get a replacement key fob.

What if my key fob still doesn’t work after programming it?

If your key fob still doesn’t work after programming it, there are a few possible reasons and solutions:

1.The battery in your key fob may be too low or dead. You can try replacing the battery with a new one and repeat the programming steps.

Make sure that the battery is inserted correctly and securely.

2.The key fob may be damaged or defective. You can check for any visible signs of damage, such as cracks, dents, or loose parts.

You can also try using another key fob if you have one and see if it works.

If the key fob is faulty, you will need to get a new one from a dealer or a locksmith.

3.The key fob may be out of range or blocked by interference.

You can try moving closer to your vehicle or away from any sources of interference, such as metal objects, electronic devices, or other vehicles.

You can also try pointing the key fob directly at your vehicle or at different angles.

4.The keyless entry system of your vehicle may be malfunctioning or disabled.

You can check your owner’s manual or contact your dealer for more information on how to troubleshoot or reset the system.

You may need to take your vehicle to a service center for diagnosis and repair.
