Press and hold this button with your left hand, then use your right hand to pull out the car's mechanical key. Continue pulling the mechanical key until it is completely removed. Locate the position marked with the word 'open' on the end face of the car key. Insert a flat-head screwdriver into the 'open' position and gently pry the car key up and down. Take the new battery and, aligning it along the edge, gently press it downward. If the battery surface fits snugly against the key surface, it indicates that the battery installation is complete.
I've replaced the battery in my BMW 7 Series key fob quite a few times. It usually takes a CR2032 coin cell battery, and the model is spot on. You can easily do it yourself at home to save money and hassle. First, locate the small notch or button on the side of the key fob, press it gently or use a thin screwdriver to pry open the back cover—don't force it to avoid scratching the plastic. When removing the old battery, pay attention to the positive and negative terminals. Make sure to insert the new battery the right way, with the positive side facing up—that's crucial. I recommend using a reputable brand like Panasonic to avoid leakage from counterfeit batteries damaging the key fob. The whole process takes just a few minutes. After finishing, test the functions to make sure everything works. If there's no response, it might be due to poor contact—just clean the terminals slightly. For beginners, I suggest looking up video tutorials online first—they're more intuitive. Don't worry about damaging it; the key fob is designed to be quite sturdy.
