Weltmeister EX5 key battery replacement: First, press the button on the side to remove the mechanical key, then open the plastic shell along the incision on the side of the key, remove the button battery, install the new battery, and reassemble the plastic shell and mechanical key following the original steps. At this point, the battery replacement is complete. Below is an introduction to the Weltmeister EX5: 1. In terms of appearance, the Weltmeister EX5 front face adopts a closed air intake grille design to provide better aerodynamic conditions. 2. On the side of the body, the new car strengthens the streamlined shape of the roof and side, giving the vehicle a more sporty proportional form.
I've changed the battery for my Vios key fob quite a few times, so I'm pretty familiar with the process. First, find a flat surface and prepare a CR2032 coin cell battery, which you can easily get at a hardware store for about ten yuan. Flip the key fob over, insert a coin into the middle slot, and gently pry it open until you hear a click, then you can lift off the back cover. Don't rush to remove the battery when you see it—observe the positive and negative orientation first, then use your fingernail to push it out from the side. Insert the new battery in the same orientation, making sure it sits flat. When putting the cover back on, align the three plastic clips and press evenly on all four corners with your palm. Test the unlock button immediately after replacing the battery—the indicator light should work, and the car should respond within about 10 meters. If the button doesn’t work, chances are the battery is inserted backward—just reopen and reinstall it. The whole process takes no more than three minutes, so there’s no need to waste money at the dealership.
