Common Tesla Model X Key Fob Problems and Solutions

Here’s a breakdown of common issues Model X owners face with their key fobs and how to address them:

1. Key Fob Not Responding

If your Tesla Model X key fob is completely unresponsive, the most likely culprit is a depleted battery.

Solution:

• Replace the battery: The key fob uses a standard CR2032 battery. You can easily replace it yourself by gently prying open the back panel with a small flathead screwdriver.

2. Key Fob Intermittently Working

Experiencing intermittent functionality with your key fob can be frustrating. Here’s what could be causing it:

Solution:

• Check Battery Connection: Ensure the new battery is properly seated and making good contact.
• Interference: Other electronic devices, particularly those using Bluetooth, can interfere with the key fob’s signal. Try moving away from potential sources of interference.
• Distance: The key fob has a limited range. Make sure you’re within a reasonable distance from your Model X.

3. Key Fob Won’t Unlock/Lock the Car

This issue can stem from problems with both the key fob and your Tesla Model X.

Solution:

• Key Fob Battery: As always, start by ruling out a weak key fob battery.
• Vehicle Wake-Up: Ensure your Model X is awake. Tap the driver-side window or open a door to wake it up.
• Resync Key Fob: If replacing the battery doesn’t work, you might need to resync the key fob Tesla:
  1. Ensure your Model X is in park.
  2. Place your key fob on the center console, below the USB ports.
