If you’re experiencing issues with your 2014 BMW 320i key fob, a dead battery might be the culprit. Luckily, replacing the battery is a quick and easy process that you can do yourself. Let’s dive into how to get your key fob back in working order.
Recognizing a Dying Key Fob Battery
Before you start digging for tools, how can you be sure it’s actually the battery? Here are some telltale signs:
- Decreased Range: Is your car only unlocking when you’re standing right next to it?
- Intermittent Functionality: Does your key fob work sometimes but not others?
- Warning Messages: Your BMW may display a “Key Battery Low” warning on the dashboard.
If any of these sound familiar, it’s time for a fresh battery.
What You’ll Need:
- A new CR2032 battery (easily found at most stores)
- A small flat-head screwdriver
- Possibly a small pick or tweezers (depending on your key fob model)
Replacing the Battery: Step-by-Step
-
Open the Key Fob: Look for a small release button or notch on the back or side of your key fob. Gently press it while pulling the key blade away from the fob to separate the two halves.
-
Locate the Battery: The CR2032 battery will be sitting inside the fob, usually in a designated slot.
-
Remove the Old Battery: Some batteries can be pried out gently with a fingernail. If not, carefully use your flat-head screwdriver or a pick to lift the battery out of its compartment.
-
Install the New Battery: Ensure the positive (+) side of the new battery faces up (or as it was in the original placement). Gently press it into place.
-
Reassemble the Key Fob: Align the two halves of the key fob and press them firmly together until you hear a click.
-
Test It Out: Try locking and unlocking your car to make sure the new battery is working correctly.

Still Having Issues?

- Key Fob Programming: In some cases, you might need to re-synchronize your key fob with your car after a battery change.
- Key Fob Damage: Inspect your key fob for any physical damage that might be affecting its functionality.
- Other Car Issues: It’s possible, though less likely, that the issue lies with your car’s receiver rather than the key fob itself.
