Understanding Your 2020 BMW X3 Key Fob

Before diving into the replacement process, it’s important to understand the components of your key fob.

Over time, this battery will naturally deplete, requiring a replacement. Ignoring a low battery warning can lead to unexpected lockouts and inconvenience.

Knowing when to replace your 2020 Bmw X3 Key Fob Battery is crucial. Common signs of a dying battery include decreased key fob range, intermittent functionality, and the appearance of a low battery warning on your vehicle’s dashboard.

What Type of Battery Does a 2020 BMW X3 Key Fob Use?

The 2020 BMW X3 key fob uses a CR2032 battery. This is a common lithium coin cell battery that’s readily available at most electronics stores, pharmacies, and online retailers. It’s always a good idea to have a spare CR2032 battery on hand, so you’re prepared when the time comes for a replacement.

Syncing Your Key Fob After Battery Replacement

After replacing the battery, you may need to re-synchronize your key fob with your 2020 BMW X3. In most cases, the key fob will automatically resync after battery replacement. However, if you experience any issues, follow these steps:

2. Insert and remove the key fob: Insert the key fob into the ignition slot and remove it immediately.
3. Press and hold the start/stop button: Press and hold the start/stop button for about 10-15 seconds until the dashboard lights up. Your key fob should now be synced.

Troubleshooting Common Issues

Sometimes, you might encounter issues even after replacing the battery. Here are some common problems and solutions:

• Key fob still not working: Try repeating the synchronization process. If the issue persists, there might be a problem with the key fob itself, and you may need to consult a BMW dealership or a qualified automotive locksmith.
• Key fob works intermittently: Check the battery contacts inside the key fob for any corrosion or dirt. Clean them with a cotton swab and alcohol if necessary.
