First, press the button on the side to pull out the mechanical key, then insert it into the groove on the back cover. Gently push to pop open the back cover and remove the battery. Below is some relevant information about Mercedes key batteries: 1. The lifespan of a Mercedes key battery is generally two years, while the original factory battery can last up to six years. 2. When the key battery is depleted, the Mercedes vehicle will provide two types of alerts: one is when you press the ignition switch, the dashboard will display a message to replace the key battery; the other is when you press the lock or unlock button on the key, if the indicator light on the key dims or doesn't light up, it indicates that the key battery needs to be replaced.
I just replaced the battery for my new BMW X1 key, and it felt super easy. The key has a smart design with a small button or gap on the back—just press it gently to open the rear cover. Avoid using metal tools to pry it open; instead, use a small plastic piece or your fingernail to give it a light push. The battery is a CR2032 coin type. When removing it, carefully check that the positive side faces upward. Take out the old one and replace it with the new one, ensuring it sits securely. Close the cover until you hear a click, and you're done. I recommend keeping a spare battery of the same model handy—you can buy them at supermarkets or online, and they typically last about 1-2 years. If the remote stops working or the light doesn't turn on, replace the battery immediately to avoid being locked out unexpectedly. I also suggest cleaning the key surface with a soft cloth to prevent dust from getting inside and affecting the battery contacts. Doing this on a flat table is the safest way, and the whole process takes less than 5 minutes—saving both money and hassle.
