Video tutorial

The video shows how to replace the battery in a 2019 Ford Focus key, but it also applies to a Ford Fiesta. It is a very simple operation, but be careful as, unlike many other remotes, this one has two separate compartments: the emergency blade and the battery compartment.

To extract the battery, lever on the side of the key with a small screwdriver, open the key into two parts, and remove the flat battery. Insert the new battery, type CR 2032, in the correct orientation and close the key, aligning the two parts with the help of the pin present in one of the two halves.

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.
