I've always driven BMWs, and the blade key uses a CR2032 battery, which is the standard for most BMW smart keys. It falls under the category of button cell batteries—compact yet durable. I recall changing it countless times—whenever the key malfunctions or the buttons respond slowly, it's likely the battery is nearly depleted. It's recommended to check it every two years, but if you frequently use remote functions, the battery life may be shorter. When replacing, gently pry open the key casing using a plastic tool to avoid scratches, remove the old battery while noting its orientation, and insert a new CR2032. You can find them at supermarkets or online—opt for reputable brands like Panasonic and avoid cheap, low-quality options to prevent recurring issues. Also, avoid prolonged exposure to high temperatures to extend battery life.
