Owning a Tesla is an experience that blends cutting-edge technology with everyday convenience. One of the most remarkable features is the ability to use your smartphone as a key, eliminating the need for a traditional key fob or even the key card for most daily interactions. This guide will walk you through the process of setting up your phone as a Tesla key, ensuring you can unlock, drive, and enjoy your vehicle with unparalleled ease. Let's get started!
Step 1: Prepare Your Phone and Tesla for Pairing
Before you begin, let's make sure everything is in tip-top shape for a smooth pairing process. This initial setup is crucial for seamless operation.

A. Download and Log into the Tesla Mobile App
First things first, you'll need the official Tesla mobile app.
For iPhone users: Head over to the Apple App Store.
For Android users: Find it on the Google Play Store.
Once downloaded, open the app and log in using your Tesla account username and password. It's vital to remain logged in to your Tesla account within the app for your phone to function as a key. If you have multiple Tesla vehicles linked to your account, ensure the specific vehicle you want to pair with is currently selected in the app.
B. Enable Essential Phone Settings
Your phone needs to be ready to communicate with your Tesla via Bluetooth.
General Bluetooth Settings: Navigate to your phone's main settings and ensure Bluetooth is turned on. If it's already on, try toggling it off and on again to refresh the connection.
Tesla App Bluetooth Permissions: This is a commonly overlooked step! Go to your phone's settings, find the Tesla mobile app, and then look for its Bluetooth settings. Make sure Bluetooth access is enabled specifically for the Tesla app.
Location Services: For the best experience, and for features like Walk-Away Door Lock to function correctly, enable location access for the Tesla app. Go to your phone's settings, find the Tesla app, select "Location," and choose "Always." Keeping the app running in the background will also improve its responsiveness as a key.
Disable Battery Optimization (Android specific): On some Android devices, aggressive battery optimization can hinder the app's background operation. Check your phone's battery settings and ensure the Tesla app is set to "Unrestricted" or similar, to prevent it from being put to sleep.
C. Configure Tesla Vehicle Settings
Your Tesla also needs to be ready to accept your phone as a key.
Allow Mobile Access: While inside your Tesla, touch the touchscreen to navigate to Controls > Safety > Allow Mobile Access. Ensure this setting is enabled. This allows your phone to communicate with your vehicle.
Ensure Good Battery Levels: Both your phone and your Tesla should have sufficient battery charge. A low phone battery can sometimes disable Bluetooth functions, and a very low vehicle battery might also impact Bluetooth connectivity.

Step 2: The Pairing Process
Now that both your phone and Tesla are prepped, let's initiate the pairing.
A. Start the Setup from the Tesla App
Be inside or near your vehicle.
Open the Tesla mobile app on your phone.
On the main screen of the app, you should see an option like "Set Up Phone Key." Tap on this.
Alternatively, you can navigate within the app to Security > Set Up Phone Key.
B. Follow On-Screen Prompts
The app and your vehicle's touchscreen will guide you through the remaining steps.
The Tesla app will start searching for your car via Bluetooth.
It will then attempt to authorize your phone as a key.
You might be prompted to confirm the pairing on your phone or the car's touchscreen. Follow these prompts carefully.
If your Tesla has been manufactured prior to approximately February 2025, you might be asked to scan an already paired key card or key fob on the card reader (usually located behind the cup holders on the center console or on the driver's side door pillar). This acts as a security measure to confirm you have authorized access to the vehicle.
C. Confirmation
Once the pairing is successful, the Tesla app will confirm that your phone key is connected. On your Tesla's touchscreen, if you go to Controls > Locks > Keys, you should see your phone listed as a key, often highlighted in white, indicating it's active. If it's grayed out, it's not connecting properly.
Step 3: Enjoying Your Phone Key
With your phone successfully paired, you can now experience the ultimate convenience.
Tip: Reading in short bursts can keep focus high.
A. Automatic Locking and Unlocking
Your phone key supports automatic locking and unlocking.
As you approach your Tesla with your phone, its Bluetooth signal will be detected, and the doors will unlock automatically when you pull a door handle.
Similarly, when you exit the car and walk away with your phone, the doors will automatically lock. This feature is called "Walk-Away Door Lock" and can be enabled/disabled in your vehicle's settings (Controls > Locks).
B. Driving Your Tesla
Once inside with your phone key, you can simply press the brake pedal to start your Tesla and shift into drive or reverse. No need to place your phone on the wireless charger or use a key card – it's truly a seamless experience!
C. Troubleshooting Tips if it Doesn't Work
If your phone key isn't working as expected:
Toggle Bluetooth: Turn Bluetooth off and on again on your phone.
Restart Tesla App: Close the Tesla app completely and reopen it.
Reboot Phone: Sometimes, a simple phone reboot can resolve connectivity issues.
Check App Permissions: Double-check all the Bluetooth, Location, and background app refresh permissions for the Tesla app on your phone.
Check Phone Key Setting in App: Open the Tesla app, go to "Security & Drivers," and ensure "Phone Key" is enabled. This might occasionally reset after app updates.
Update Software: Ensure both your phone's operating system and your Tesla's software are up to date.
Remove and Re-add Phone Key: As a last resort, you can remove your phone as a key from the Tesla's touchscreen (Controls > Locks > Keys, then select your phone and "Remove") and then re-add it following the steps above. You will need a working key card or another paired key to do this.
