To replace the battery in an Opel Mokka B remote, extract the metal emergency key: look for the small release button on the side of the remote, press it, and slide out the blade. At this point, using a flathead screwdriver (or a plastic tool), pry in the gap along the edge of the remote to separate the two halves of the shell.

Proceed carefully to avoid damaging the plastic clips. Once opened, you will find the button battery, which is a CR2032 (the most common for these remotes).

Carefully remove the old battery, paying attention to the orientation: the positive (+) side must face upwards. Insert the new battery, close the remote by pressing firmly until you hear the snap of closure.

Reinsert the emergency key and check the operation by pressing the buttons.

How to Activate the Disabled TRC on the Toyota Yaris?

As the video clearly shows, disabling or activating the traction control (TRC or ESP) on the Toyota Yaris is very simple. By default, the traction system activates every time the vehicle is started. To disable it, simply press the button depicting a skidding car located in the centre of the vehicle where the controls are, such as the hazard lights and the radio, but near the handbrake. Once disabled, the TRC off light will illuminate on the dashboard. To reactivate it, just press the same button again.
