In this video, we will show you how to replace the battery in a Mercedes A-Class key remote. Take your ignition remote and pull out the metal key (located inside).

Once the metal key is removed, use a screwdriver to pry open the plastic cover of the remote and press inside. When you hear a click, it means the cover is open.

Use a small screwdriver to remove the dead battery, take a new one (same size and voltage), and replace it. Reassemble the key remote cover by pressing on the key cover until you hear it click into place. Check that it functions correctly.

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.
