Is your 2001 BMW X5 key fob no longer working as it should? A common culprit is a dead battery. Instead of heading straight to the dealership and spending a significant amount on a replacement, you can easily tackle this yourself. This guide will walk you through replacing the battery in your 2001 BMW X5 key fob, saving you time and money.
The process requires a few simple tools and a replacement VL2020 battery with 90-degree prongs. You’ll need a soldering kit, some new solder, and a bit of super glue to reseal the key fob. While opening the key fob case can be a bit tricky, with a little patience, you can accomplish this battery replacement at home.
First, carefully use a utility knife to split open the key fob case along its seam. It might require some firm but gentle pressure to pry it apart without damaging the plastic. Once open, you’ll see the old battery. Remove the old battery and any remaining solder from the contact points.
Now, take your new VL2020 battery and position it correctly. Solder the new battery in place. Ensure you have a good connection, but be careful not to use excessive heat, which could damage the components. A common mistake is missing a tiny, fine wire that might detach during the process. If your key fob doesn’t work after the initial battery replacement, double-check for any loose wires near the battery prongs and resolder if necessary. These wires can be incredibly thin and easily overlooked.
After soldering, it’s wise to test the key fob before permanently sealing it. Temporarily tape the key fob case together and test the remote locking and unlocking functions on your BMW X5. If everything works, you can proceed to reseal the case.
Apply a small amount of super glue to the seam of the key fob case. Carefully press the two halves together, ensuring a tight seal. Be cautious with the super glue to avoid getting it on your fingers or the internal components of the key fob. Allow the glue to dry completely.
With the case sealed and the new battery installed, your 2001 BMW X5 key fob should be working perfectly again. You’ve successfully completed a DIY 2001 Bmw X5 Key Fob Battery Replacement! This simple repair can restore the functionality of your key fob and save you the expense of a professional replacement.
