Replacing a dying battery in your 2015 BMW key fob is a quick and easy process you can do yourself, saving you a trip to the dealership. This guide will walk you through each step, ensuring you’re back to enjoying seamless access to your vehicle in no time.
Identifying a Low Key Fob Battery
Before you begin, it’s helpful to confirm that a low battery is indeed the issue you’re facing. Here are a few common signs:
- Decreased signal range: You might find yourself having to stand closer to your car for the key fob to lock or unlock the doors.
- Inconsistent response: The key fob might work intermittently, requiring multiple presses to elicit a response.
- Dashboard warning message: Your BMW might display a warning message indicating a low key fob battery.
If you’re experiencing any of these symptoms, it’s highly likely that replacing the battery will resolve the problem.
What You’ll Need
To replace the battery in your 2015 BMW key fob, you will need the following:
- A new CR2032 battery (widely available at most stores)
- A small flat-head screwdriver
- Optional: A small plastic prying tool (or your fingernail if it’s strong enough)
Step-by-Step Guide to Battery Replacement
Step 1: Access the Battery Compartment
Hold your BMW key fob with the key ring facing down. Locate the small, rectangular release button on the back of the fob. Use the flat-head screwdriver to gently press the button. This will release the metal key from the fob.
Step 2: Open the Key Fob
With the metal key removed, you’ll notice a small slot where it was inserted. Insert the tip of your flat-head screwdriver (or your plastic prying tool) into this slot and gently pry open the two halves of the key fob. You should hear a slight click as the casing separates.
Step 3: Replace the Battery
Inside the key fob, you’ll see the CR2032 battery. Carefully remove the old battery by prying it up from the side with your screwdriver or prying tool. Avoid touching the battery terminals. Now, insert the new CR2032 battery, making sure the positive (+) side faces up, just like the old one.
Step 4: Reassemble the Key Fob
Align the two halves of the key fob and press them together firmly until you hear a click. Ensure the casing is securely closed.
Step 5: Reinsert the Metal Key
Slide the metal key back into its slot on the key fob until it locks into place.
Testing Your New Battery
After replacing the battery, test the key fob by trying to lock and unlock your car’s doors and starting the engine. It should be working perfectly now!
