Changing the battery of your Citroën C3 key is a simple operation that will help you avoid inconveniences when it stops working. Take a small screwdriver or a coin and look for the slot on the back of the key. Gently pry it open, without forcing it too much.

Once open, you will see the battery: it is usually a CR2032. Carefully remove it and insert the new one, paying attention to the polarity (+ facing upwards). Close the shell by pressing the two sides firmly until you hear a click.

Test the remote immediately to make sure it works. If it doesn't work, check that the battery is positioned correctly.

Now you're all set, no more opening problems!

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.
