Have you tried to unlock your Hyundai with the remote and failed? It is probably time to replace the battery in the device as it is flat. Fortunately, you are in the right place; we will replace it quickly together.

On the side of the buttons that lock or unlock the vehicle, press the button on the edge and simultaneously pull out the actual key. After removing it from its slot, you can use a lever to separate the two sides of the remote. Continue until it is disassembled.

Now proceed with the battery replacement. You can reassemble everything in reverse order.
