Press the designated button to extract the manual key from the casing. Then, using a small flat screwdriver, pry along the entire length of the remote's seam until it splits into two parts.

You will now see the CR2032 3 Volt battery. Still using the small screwdriver, remove it from its holder and insert the new one you purchased (available at any hardware store or large supermarket).

Reassemble the remote by simply snapping the two halves back together and insert the manual key. It's that simple!

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.
