What is Tesla Remote Start?
A very useful function that allows you to start your Tesla from a distance using your mobile app or key fob.
You can even warm up or cool down according to your comfort through this function before getting inside your car. It offers seamless access to your vehicle without physical interaction.
How Does Tesla Remote Start Work?
Tesla Remote starts when you use the mobile app or key fob to begin your Tesla remotely, then it sends a secure signal to the car’s computer system.
Then, it interprets the command and triggers the startup sequence.
This signal is encrypted and sent through a highly secure network to prevent unauthorized access. Ensures that only authorized individuals can activate remote start.
Once your car receives the signal, the computer system engages the necessary components (such as the ignition, electric motors, and other relevant systems) to start the car.
Methods of Remotely Start Your Tesla:
Tesla provides several options for remotely starting your car:
Tesla Mobile App:
The Tesla Mobile App communicates with your vehicle through a cellular connection and is available for both iOS and Android devices.
Just download, launch, and set up the Tesla App on your phone to pair it with your Tesla Model. You can even adjust the temperature and turn on the heat or air conditioning (if necessary) via this App.
This App also offers additional features such as locking and unlocking the doors, honking the horn, and tracking your car’s location.

Key Fob:

The key fob allows you to lock, unlock, and start your Tesla with the push of a button. Press and hold the trunk button on the key fob for a few seconds to start your car remotely.
Tesla key fob also enables other functionalities like summoning your car from a parking spot or opening the trunk remotely.
Scheduled Departure:
Tesla offers a unique feature known as “Scheduled Departure.”
Tesla Owners or authorized users can input their desired departure time through Tesla’s touchscreen display or mobile app. The car will automatically initiate the remote start process at the specified time.
Tesla Energy Gateway:
The “Tesla Energy Gateway” is a more advanced and comprehensive method for remotely starting any Tesla car. This intelligent system connects the car to a Tesla Powerwall or a solar energy setup located in the owner’s home.
Since this integrated solution utilizes the energy stored in the Powerwall or generated from the solar system, it also minimizes dependency on grid energy and promotes sustainability.
Apple Watch App:

Another innovative way to remotely start your Tesla is to use the Apple Watch as the Key Fob.
If you have an Apple Watch, download the “Watch app for Tesla” or “Remote for Tesla” from the App Store. Just download the App, go to Settings > Bluetooth > Click on that slider to enable.
You will need to use your Tesla account credentials to log in and authorize the Watch App for your car access. Apple Watch can also unlock your Tesla without any internet connection.

Common Reasons for Tesla Remote Start Failure and How to Fix Them:
On certain occasions, Tesla remote start may not work as expected or fail.
If you find yourself experiencing this issue, there are a few common reasons for the failure and steps you can take to resolve the problem:
1. Insufficient Weak Battery Charge:
The process requires a certain level of battery power to function properly. So, if the battery charge in your car or Key Fob is low or insufficient, the remote start may not work.
Fix:
Before using the remote start, make sure your Tesla’s battery is fully charged.
Check the battery in the key fob and replace it, if necessary, before trying again.
2. Unstable Cellular Signal or Weak Network Connectivity:
Remote start requires a strong, stable, and reliable connection to Tesla’s servers to initiate the start command. Poor connectivity caused by interference or distance can hinder functionality.
For example, if you are in an area with poor network coverage or experiencing temporary connectivity issues, remote start may not work.
Fix:
Try moving to an area with better signal strength or wait till the network problems are fixed before attempting remote start again.
Check that you are within the recommended range (usually 150-200 feet) for a remote start. If required, get closer to your car to make a better connection.
3. Incorrect Remote Start Configuration:
Sometimes, Tesla remote start may fail to work due to an incorrect configuration of the feature within the Tesla mobile app or vehicle settings.
Fix:
Navigate to the Tesla mobile app’s car controls and check to see if the remote start feature is active. Confirm that it is Enabled on your Mobile App too.
Check to see if your vehicle’s settings permit remote start. If any changes are required, make them in both places and try remote start again.
4. Software Updates:
Remote start issues may arise if the software on the key fob, Mobile App, or your Tesla car is outdated.
Fix:
Check that your Tesla software is up to date and you’re running the latest version of Tesla Mobile App software.
Update the software on your car (if needed) by going to the “Settings” menu on your Tesla’s touchscreen display> Select “Software Updates.”
After updating, restart your car and mobile app to verify the changes take effect.
5. Security Restrictions:
Tesla builds its EVs with extensive security features to prevent unwanted access and misuse. However, excessive restrictions can interfere and cause unresponsive or failed activation of remote start commands.
If you are encountering symptoms like:
- If your car becomes Unresponsive (providing no clear indication of execution),
- Getting Error Messages stating, “Security preventing the function from working” on your car’s Touchscreen display or “Mobile App“
- Getting a notification indicating limited range access due to security protocols.
Then it’s most probably due to your car’s security settings.
Fix:
Always keep your Tesla up to date to avoid common bugs and security issues.
Visit the “Security Settings” on your car’s touchscreen to review and adjust.
Verify that your car has stable and uninterrupted connectivity.
