Using a small flat screwdriver, open the two halves of the remote by prising apart at the small slot located at the back, where the keyring holder may be found. Then, extract the old battery by sliding it out of its holder, remove any oxidation residues with contact spray, and insert the new one, ensuring the polarity is correct and that the voltage of the new battery matches that of the old one. Finally, close the halves securely and check the operation of both buttons.

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.
