2019 BMW Key Fob Battery Replacement: A Quick Guide

Is your 2019 BMW key fob acting up? If you’re experiencing issues like reduced signal range or unresponsive buttons, it’s highly likely that your key fob battery needs replacing. Thankfully, replacing the battery in your 2019 BMW key fob is a simple task that you can easily do yourself at home, saving you a trip to the dealership.

How to Replace Your 2019 BMW Key Fob Battery: Step-by-Step Instructions

Before you begin, you’ll need a CR2032 battery, which is commonly used in key fobs and other small electronics. You can find these batteries at most hardware stores, auto parts stores, and online retailers.

Once you have your new battery, follow these easy steps:

1. Locate the release button: On the backside of your key fob, find the small, indented button. This is the release button for the emergency key.

2. Release the emergency key: Using your fingernail or a small flathead screwdriver, gently press and hold the release button while simultaneously sliding the emergency key blade out of the fob.

3. Open the key fob casing: With the emergency key removed, you’ll notice a small slot where the blade was inserted. Insert the tip of your flathead screwdriver (or another similar tool) into this slot and carefully pry open the key fob casing. Be gentle to avoid damaging the plastic.

4. Replace the battery: Once the casing is open, you’ll see the old CR2032 battery. Carefully remove it and replace it with the new one, making sure to match the positive (+) side facing up.

5. Reassemble the key fob: Align the two halves of the key fob casing and press them firmly together until you hear a click, indicating the casing is securely closed.

6. Reinsert the emergency key: Slide the emergency key blade back into its slot on the key fob until it locks in place.

7. Test the key fob: Press the buttons on your key fob to ensure it’s functioning correctly. If everything works as it should, you’ve successfully replaced your battery!

Why Won’t My 2019 BMW Key Fob Work After Battery Replacement?

If your key fob is still not working correctly after a battery change, there could be a few reasons why:

• Incorrect battery installation: Double-check that you’ve installed the new battery correctly, with the positive (+) side facing up.

• Key fob needs to be resynced: In some cases, you may need to resync your key fob with your BMW after replacing the battery. Refer to your owner’s manual for specific instructions on how to do this for your model.

• Other underlying issues: If resyncing doesn’t solve the problem, there might be other issues with your key fob, such as damaged internal components. In this case, it’s best to consult with a qualified BMW technician or locksmith.
