2 Answers
Toyota Vios remote battery replacement method is: 1. Locate the button on the back of the car key to remove the mechanical key; 2. Insert a screwdriver wrapped with a small cloth into the small pit in the middle of the mechanical key; 3. Twist the key shell open by turning left and right; 4. Remove the key cover, take out the circuit board, and replace the battery. Taking the 2021 Toyota Vios as an example, it is a compact car with body dimensions of: length 4435mm, width 1700mm, height 1490mm, wheelbase 2550mm, minimum ground clearance 160mm, and body weight 1070kg.
My car is a Toyota Vios, and I've changed the remote key battery several times. It's quite simple: First, flip the remote key over, and you'll see a small groove on the back. Use a coin or a small flathead screwdriver to gently pry open the casing—don't use too much force to avoid cracking it. Inside, there's a small round battery, usually a CR2032. When removing it, remember the position of the positive and negative terminals. When inserting the new battery, make sure the positive side faces upward. After closing the casing, test if the buttons light up. If they don't work, realign the battery. You can buy the battery cheaply at supermarkets or online, usually for just a few dollars. It's best to replace it once a year to prevent sudden power loss affecting your car use and to save the hassle of going to a repair shop. If you encounter difficulties, taking a photo and asking for help is also convenient. Doing it yourself saves money and gives a great sense of accomplishment.
