Replacing a BMW key fob battery is a pretty straightforward process. With the right tools and key information, it is a DIY project that can be handled with ease. Below is a step-by-step guide on how to replace a BMW key 4 fob battery.
Car owners will need a flat-head screwdriver and a new battery (CR2450) to get the job done. They should also consult the owner’s manual for specific instructions related to their BMW model.
Open the Key Fob
Use the flat-head screwdriver to pry open the key fob. Insert the screwdriver into the seam of the key fob and twist gently to separate the two halves. Exercise great care not to damage the plastic casing.
Remove the Old Battery
Take note of how the old battery is positioned (positive and negative sides) and remove it. It should come off easily, but if it’s stuck, gently pry it off with the screwdriver.
Insert the New Battery
Place the new CR2450 battery in the same position as the old one, ensuring the positive (+) side faces the same direction as before.
Close the Key Fob
Carefully align the two halves of the key fob and press them together until they snap. Ensure the fob is tightly sealed to keep out moisture and dirt.
Test the Key Fob
Go to the BMW and test the key fob to ensure it’s working properly. If the car doesn’t respond, double-check that the battery is installed correctly and the fob is closed securely.
Q1: Can I program the BMW key fob myself?
A1: While it is possible to program some BMW key fobs yourself using DIY methods, many require specialized equipment or knowledge. It is recommended to have a professional program the key fob to ensure proper functionality and security.
Q2: What should I do if my BMW key fob stops working?
