How to Replace the Battery in a BMW Remote?

[AdelineMarie]

Here is the tutorial for replacing the battery in a BMW car key: 1. Remove the spare key located at the back of the key. 2. Use a tool to pry open the back cover. 3. Take out the old battery and insert a new one (note: the new battery model must match the old one). 4. Close the back cover and reinsert the spare key. Precautions for using the car key are as follows: 1. Frequently placing the smart car key and mobile phone together may inevitably cause the smart car key to malfunction. This is because the chip in the smart key can sometimes be interfered with by the phone's frequency, which may temporarily disable the key's remote function. 2. The battery life of a smart car key is approximately 1 year. Due to the varying frequency of use of the car key, the battery consumption will differ. Using the car key at different distances will also affect the power consumption.
