If you notice that the remote key for your vehicle is no longer working and cannot open the doors, you need to replace the key battery. To do this, the description below provides all the instructions on how to proceed.

After purchasing a new battery, first remove the emergency key and use it to pry off the rear cover. This will expose the battery, which you can remove with a sharp object and replace with the new one, ensuring the polarity is correct.

Reattach the cover and insert the emergency key back.

How to Remove the Rear Seat of a Hyundai Tucson?

To remove the rear seat of a Hyundai Tucson, follow these steps. Start by moving the front seats to their most forward position to gain space. Next, locate the release lever on the underside of the rear seat, near the floor. Press this lever down while pulling the seat upwards to unlock it from the anchor pins. Once unlocked, tilt the seat upwards and forwards to remove it from its position. Repeat this process for both sides of the rear seat. Be careful of any electrical cables or components that may be connected to the seat during removal. Once the rear seat is removed, the disassembly is complete.
