Bestune B30 car key battery replacement method is as follows: 1. There is a round button on the side of the car key. Press this button with one hand and pull out the mechanical key with the other hand; 2. Locate the gap in the middle of the top of the key and insert a flat-head screwdriver; 3. Pry the key up and down until a gap is created; 4. Take out the key circuit board, gently push one side of the battery with your finger, and remove the battery; 5. Install the new battery with the positive side facing up. In terms of body dimensions, the Bestune B30 has a length, width, and height of 4625mm, 1790mm, and 1500mm respectively, with a wheelbase of 2630mm.

I found that changing the battery for the Besturn B30 car key is actually quite simple, and I've done it myself several times. First, look at the back of the key—there's usually a small gap or slot. Gently pry it open with a fingernail or a small flathead screwdriver to remove the battery cover. Then carefully take out the old battery, making sure to note its polarity (usually positive side up). The replacement battery should be the same type—CR2032 button cell—which is readily available online or in supermarkets at a very affordable price. When inserting the new battery, ensure the polarity matches the old one to avoid poor contact. Finally, press the cover back firmly until you hear a click, securing it in place. The whole process takes just a few minutes and requires no special tools—just clean hands to prevent static discharge. I recommend keeping a spare battery in the car in case the key suddenly stops working and you can't unlock the door. Typically, the battery lasts one to two years; if the remote control range shortens, it's time for a replacement. This simple maintenance saves time and money while avoiding awkward situations when driving.
