Signs Your Key Fob Battery Needs Replacing
Before we dive in, let’s look at some telltale signs that your key fob battery is on its way out:
- Decreased Range: Notice you have to stand closer to your X3 to lock or unlock the doors? That’s a classic sign of a weakening battery.
- Slow Response: If your X3 is sluggish to respond to your key fob commands, it’s another indicator that the battery might be nearing the end of its life.
- Dashboard Warning: Some BMW models, including the X3, will actually display a “Key Battery Low” warning on your dashboard when it’s time for a replacement.
What You’ll Need
You only need a couple of things for this simple DIY project:
- A New Battery: You’ll need a CR2032 battery. These are commonly available at electronics stores, auto parts stores, and even some grocery stores.
- A Small Flathead Screwdriver: This will be used to open the key fob.

Here’s a step-by-step breakdown of how to replace the battery in your 2020 BMW X3 key fob:
- Locate the Release Button: Look on the back of your key fob for a small button. This is the key blade release button.
