Last time I replaced the battery for my BMW 1 Series remote key myself, and the process was quite simple. First, find a small tool like a coin or a small screwdriver to gently pry open the tail of the key, where there's a slot. Don't use too much force to avoid damaging the casing. Remove the old battery, which is usually a CR2032 model—you can buy a new one at the supermarket or online. Make sure the positive side of the battery faces up and never install it upside down. After replacing it, close the cover and test the lock and unlock functions by pressing the key buttons. It's recommended to check the battery life every two years and replace it promptly if the key responds slowly. Perform the operation in a dry place to prevent static electricity. Doing it yourself saves the cost of a repair shop and gives a sense of accomplishment.

I recently replaced the battery in the remote control of my BMW 1 Series at home. There's a small gap at the end of the key, and you can easily separate the two halves by gently prying with a small screwdriver. Take out the old battery inside, the model is CR2032, which is easy to find in regular stores. Install the new battery, making sure the electrodes are aligned correctly, otherwise it might malfunction. Close the key shell and test the remote lock/unlock function to see if it works. I usually check it regularly to avoid being stuck when the battery runs out. The whole process takes no more than five minutes, and don't forget to clean the key surface to prevent fingerprint buildup. Sharing this DIY car repair tip with you, it's both cost-effective and convenient.
