Owning a 2018 BMW 320i means enjoying the blend of luxury and performance this iconic car delivers. But even the most finely-tuned machines need a little maintenance now and then, and your key fob is no exception. A dead key fob battery can quickly turn your sleek ride into a source of frustration. This guide covers everything you need to know about your 2018 Bmw 320i Key Fob Battery, from identifying the signs of a dying battery to replacing it yourself.
Signs Your Key Fob Battery Needs Replacing
Before you find yourself stranded, your 2018 BMW 320i will likely give you a few hints that your key fob battery is nearing its end. Keep an eye out for these telltale signs:
- Decreased Range: Is your car only responding to your key fob from a very short distance? This reduced range is often the first sign of a weakening battery.
- Intermittent Functioning: Does your car sometimes unlock with the key fob and sometimes not? This inconsistent behavior can indicate a battery on its last legs.
- Warning Messages: Your BMW is smart, and it might display a warning message on your dashboard, like “Key Fob Battery Low,” when it detects a problem.
- Slow Response Time: Notice a lag between pressing a button on your key fob and your car responding? A sluggish key fob often points to a drained battery.
What Battery Does a 2018 BMW 320i Key Fob Use?
Your 2018 BMW 320i key fob is powered by a CR2032 battery, a common type of lithium coin battery found at most electronics stores, auto parts stores, and even some supermarkets.
How to Change Your 2018 BMW 320i Key Fob Battery
Replacing the battery in your 2018 BMW 320i key fob is a surprisingly simple DIY task. Here’s a step-by-step guide:
- Locate the Emergency Key Slot: On the side of your key fob, you’ll find a small, rectangular slot. This is where your emergency key blade is stored.
- Release the Emergency Key: Insert the emergency key (or a small flathead screwdriver) into the slot and gently pry open the key fob casing.
- Identify the Battery: Inside the key fob, you’ll see the CR2032 battery.
- Remove and Replace: Carefully remove the old battery and install the new CR2032 battery, ensuring the positive (+) side faces up.
