| How To Set Up Tesla Phone Key |
A. Update Everything!
Tesla App: Make sure you have the latest version of the Tesla mobile app installed on your smartphone. Head to your phone's app store (Google Play Store for Android, Apple App Store for iOS) and check for updates.
Phone's Operating System: Ensure your phone's operating system (iOS or Android) is also up to date. Outdated software can sometimes cause compatibility issues.
Tesla Vehicle Software: Your Tesla's software needs to be current as well. On your Tesla's touchscreen, navigate to
Controls > Softwareto check for and install any available updates.
B. Connectivity Essentials
Bluetooth: This is crucial. Ensure Bluetooth is enabled on your smartphone. Go to your phone's settings and toggle Bluetooth ON.
Location Services: For optimal performance, enable location services for the Tesla app on your phone and set it to "Always" or "Allow all the time." This allows the app to detect your proximity to the vehicle effectively.
Mobile Access on Tesla: On your Tesla's touchscreen, enable "Allow Mobile Access" by going to
Controls > Safety > Allow Mobile Access. This setting permits your phone to communicate with your vehicle.Background App Refresh: For consistent functionality, especially for features like "Walk-Away Door Lock," ensure the Tesla app is allowed to run in the background on your phone.
Battery Level: Your phone should have sufficient battery charge. Some phones may limit Bluetooth functionality when the battery is critically low.
Step 2: Initiating the Phone Key Setup Process
With your preparations complete, it's time to begin the actual pairing.
A. Inside or Near Your Vehicle
You'll need to be inside or very near your Tesla for the initial setup. This ensures a strong and secure connection during the pairing process.
QuickTip: Break reading into digestible chunks.
B. Opening the Tesla App
Open the Tesla mobile app on your smartphone.
On the main screen of the app, you should see an option to "Set Up Phone Key". Tap on this.
Alternatively, you can navigate within the app to
Security > Set Up Phone KeyorSecurity & Drivers > Add Key Card(if the "Set Up Phone Key" option isn't immediately visible).
C. Following the Prompts
The Tesla app will guide you through the remaining steps. This typically involves:
Confirming Bluetooth is enabled.
Potentially confirming a pairing code displayed on both your phone and the Tesla touchscreen.
If automatic setup is unsuccessful, the app might instruct you to use a physical key card to complete the setup. This often involves placing the key card on the designated reader in your Tesla (e.g., on the center console behind the cup holders for Model 3/Y, or at the top of the left phone charger for Model S/X/Cybertruck).
D. Confirmation and Customization ✅
Once successfully paired, the Tesla app will display a confirmation message. On your Tesla's touchscreen, under Controls > Locks > Keys, you should see your phone listed as a new key. You can then tap the pencil icon next to it to customize the name of your phone key (e.g., "John's iPhone").
Step 3: Understanding and Optimizing Your Phone Key Usage
Your phone is now a key! Here's how to get the most out of it and some tips for optimal performance.
A. Automatic Locking and Unlocking ♀️
One of the best features of the phone key is its ability to automatically lock and unlock your Tesla as you approach or walk away.
To ensure this works, activate the "Walk-Away Door Lock" feature in your Tesla's settings (usually under
Locks).You might also want to enable "Acoustic Lock Confirmation" to hear a subtle honk when your car locks, providing peace of mind.
Tip: Patience makes reading smoother.
B. Driver Profiles
If you have multiple drivers for your Tesla, you can link your phone key to your specific driver profile. This means when you get into the car, your seat, steering wheel, and mirror settings will automatically adjust to your stored preferences.

Check charging status and control the charge port.
Locate your vehicle.
Open the front and rear trunks.
Flash the lights or honk the horn to find your car in a crowded parking lot.
