To replace the battery of the key on a Volkswagen Passat vehicle, we need to remove the top part of the remote control in order to access its interior and remove the emergency metal key. We then open the remote control in two parts and replace the battery with a CR 2032 model.

After removing and replacing the battery, we close the remote control and assemble the metal key inside and the top part of the remote control.

We go near the car to test its operation; if it does not work, it may be necessary to reprogram the key.

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.
