If you notice that the car door does not open when using the remote key, it may be necessary to replace the key battery. Below are the operational instructions, and you can also check the video.

First, extract the emergency key and insert it into the gap between the cover and the key itself to pry off the cover. Underneath, there is the battery compartment protected by a silicone cover.

Lift this cover, remove the battery, and replace it with a new one, ensuring the positive terminal is facing up. Finally, reattach the cover and insert the emergency key.
