Your Tesla key fob is an essential tool for accessing and starting your car. When it stops working, it can be frustrating and disruptive. Whether you’re unable to unlock your doors, start the engine, or use other features, it’s important to address the issue quickly. Fortunately, many problems with the Tesla key fob can be easily resolved with some simple troubleshooting steps. In this guide, we’ll walk you through the most common reasons your Tesla key fob may not be working and how to fix them.
Common Reasons Your Tesla Key Fob Might Not Be Working
1. Dead or Weak Battery
One of the most common reasons a key fob stops working is a dead or weak battery. If you haven’t replaced the battery in a while, it may be time to do so.
- Solution:
- Replace the key fob battery. Tesla key fobs typically use a CR2032 coin cell battery.
- To replace the battery:
- Use a small flathead screwdriver or coin to pry open the fob’s casing.
- Remove the old battery and insert a new one, ensuring it is positioned correctly.
- Close the key fob and test it to see if it works.
2. Key Fob Out of Range
Tesla key fobs are designed to work within a certain range of the car. If you are too far from the vehicle, the fob won’t be able to communicate with it.
- Solution:
- Make sure you are standing close enough to your Tesla. Try pressing the button on the key fob while standing directly next to the car.
- Additionally, if you’re trying to use the key fob to start the car, ensure that the key fob is inside the vehicle as it needs to be detected to start the engine.
3. Interference or Signal Blockage
Key fobs use radio frequency signals to communicate with your car. Sometimes, environmental factors or interference from other electronic devices can block the signal.
- Solution:
- Try moving to a different location and test the key fob again. Avoid areas with strong radio interference, such as near large metal objects or other wireless devices.
- If possible, remove other key fobs or electronic devices that could be causing interference.
4. Faulty Key Fob
In some cases, the key fob itself may be malfunctioning due to internal damage or a manufacturing defect.
- Solution:
- Try using a second key fob (if available) to see if the problem persists. If the second key fob works, it’s likely that the original fob is damaged or defective.
- If you suspect the key fob is damaged, you may need to contact Tesla for a replacement or repair.
5. Vehicle Needs to be Reset
Sometimes, your Tesla may need to be reset to restore functionality to the key fob.
- Solution:
- Try performing a soft reset of your Tesla:
- Press and hold both scroll wheels on the steering wheel for 10-15 seconds.
- The screen will turn off and reboot.
- Once the car restarts, test your key fob again.
- Try performing a soft reset of your Tesla:
6. Outdated Tesla Software
Your key fob may not be working properly due to outdated software in your Tesla.
- Solution:
- Ensure your Tesla’s software is up to date. Tesla frequently releases software updates that can fix issues related to key fob functionality.
- Check for software updates in your vehicle by navigating to the ‘Software’ tab in the ‘Car’ menu on the touchscreen. If an update is available, follow the on-screen instructions to install it.
7. Key Fob Needs to be Re-paired
In some cases, the key fob may need to be re-paired with your Tesla if there’s a communication issue.
- Solution:
- To re-pair the key fob with your vehicle, follow these steps:

8. Vehicle Locking or Unlocking System Malfunction
A malfunction in the vehicle’s locking or unlocking system can also prevent the key fob from working properly.
- Solution:
- If none of the previous steps resolve the issue, there may be a problem with the vehicle’s locking system. In this case, contacting Tesla customer service or visiting a Tesla service center is the best option to get the issue diagnosed and repaired.
