Over time, however, the BMW key fob may start to malfunction or lose its functionality, which can be frustrating. In such a case, you may want to open the key fob and replace the battery, repair or replace a damaged circuit board, or simply clean the key fob for better performance.
In this article, we will guide you through the steps to open a BMW key fob and provide helpful tips for troubleshooting and maintenance. So, let’s get started.
Step-by-Step Guide to Open a BMW Key Fob
Before we begin, it’s important to note that different BMW models may have slight variations in the way the key fob is opened. Therefore, we recommend checking the owner’s manual or consulting with a BMW specialist for specific instructions for your car model.
That being said, here are the general steps to open a BMW key fob:
Step 1: Remove the Physical Key
Most BMW key fobs have a physical key hidden inside the fob’s housing. To access the key, locate the button or slider on the backside of the key fob and slide it or press it to release the key. Then, insert the key into the keyhole and turn it to unlock the key fob.
Step 2: Separate the Key Fob Housing
Once you have the physical key out, you can separate the key fob housing to access the internal components. To do so, locate the seam where the two halves of the key fob meet and gently pry them apart using a flathead screwdriver or a plastic pry tool.
Be careful not to damage the edges or the internal circuit board while prying the housing apart.
Step 3: Remove the Battery and Circuit Board
Once you have opened the key fob, you will see the battery and the circuit board. To replace the battery, remove the old battery using a small flathead screwdriver or your fingernail, and insert the new one in its place.
If you need to replace or repair the circuit board, carefully remove it from the key fob housing, making sure not to damage any of the connectors or components.
Step 4: Reassemble the Key Fob Housing
After you have replaced the battery or repaired the internal components, it’s time to reassemble the key fob housing. Align the two halves of the key fob housing, and press them firmly together until you hear a snap or a click.
Make sure there are no gaps or misaligned parts, as this may affect the key fob’s functionality.
