Owning a Tesla is an experience unlike any other, and a significant part of that is the ability to use your smartphone as a key. This convenient feature allows for seamless access and control over your vehicle, making traditional keys feel almost obsolete. Let's dive into a comprehensive guide on how to set up and effectively use your phone to open your Tesla.
Step 1: Getting Started – Are You Ready to Unlock the Future?
Before we begin, let's ensure you have everything you need. Think of this as your pre-flight checklist for a smooth and effortless Tesla experience.
Do you have the Tesla Mobile App? This is the heart of your phone key. If you don't have it already, download it from your smartphone's app store (App Store for iOS, Google Play Store for Android).
Are you logged in? Make sure you're logged into the Tesla app using your Tesla account credentials. You must remain logged in to use your phone as a key.
Is your phone's Bluetooth on? The phone key relies on Bluetooth communication with your Tesla. Double-check your phone's general Bluetooth settings and ensure Bluetooth is specifically enabled for the Tesla app.
Is location access enabled for the app? For the best experience, allow the Tesla app to access your location at all times. This helps with features like "Walk-Away Door Lock."
Is "Allow Mobile Access" enabled on your Tesla's touchscreen? This is a crucial security setting. On your Tesla's touchscreen, navigate to
Controls>Safety>Allow Mobile Accessand ensure it's enabled.Is your Tesla updated? Ensure your Tesla's software is up-to-date. Outdated software can sometimes cause connectivity issues.
Do you have a backup key (key card or key fob)? While your phone will be your primary key, it's always wise to have a physical backup in case your phone battery dies or you encounter an unexpected issue. You'll also need a key card or key fob that is already paired with your vehicle to add a new phone key.

Step 2: Pairing Your Phone as a Key – The Digital Handshake
Now that you've got your ducks in a row, let's connect your phone to your Tesla. This process is generally straightforward.
Sub-step 2.1: Initiating the Pairing
Be physically close to your Tesla. For optimal pairing, it's best to be inside or very near your vehicle.
Open the Tesla mobile app.
On the main screen of the app, you should see an option to "Set Up Phone Key". Tap this. Alternatively, you might find it by navigating to
Security>Set Up Phone Keywithin the app.
Sub-step 2.2: Following the Prompts
The Tesla app will guide you through the remaining steps. You'll likely see prompts on both your phone and your Tesla's touchscreen.
Authenticate with an existing key. At some point, you'll be asked to scan an already paired key card or key fob on the designated reader in your Tesla.
For Model 3 and Model Y, the card reader is typically located behind the cup holders on the top of the center console (for vehicles manufactured prior to approximately January/February 2024). Newer models might have it on either wireless phone charger.
For Model S and Model X, the key card/fob reader is usually located on the wireless phone charger, often at the top of the left phone charger, against the center divider.
Listen for a chime – this indicates your new key (your phone) is recognized.
Once the pairing is successful, the mobile app will show a confirmation message. Tap "Done" in the mobile app.
You can then go to your Tesla's touchscreen (
Controls>Locks>Keys) to see the list of connected keys. Your phone key should now be listed and you can even customize its name by tapping the associated pencil icon.

Sub-step 3.1: Automatic Locking and Unlocking (Walk-Away Door Lock)
As you approach your Tesla, with your phone in your pocket or bag and Bluetooth enabled, the vehicle will detect its signal. The doors will automatically unlock when you pull a handle.
As you walk away from your Tesla, the vehicle will detect that your phone is no longer in proximity and will automatically lock the doors and trunk. You'll usually see the exterior lights flash and the side mirrors fold (if enabled) to confirm it's locked.
Important Note: Ensure "Walk-Away Door Lock" is enabled in your Tesla's settings if you want this automatic functionality. Be aware that if your paired phone is left inside the vehicle with Bluetooth enabled, the doors may not lock properly. In this case, you can manually lock the car using the lock icon on the touchscreen or in the mobile app.
Sub-step 3.2: Manual Locking/Unlocking via the App
Even if "Walk-Away Door Lock" isn't active, or if you simply prefer to have direct control, you can always lock or unlock your Tesla using the mobile app.
Open the Tesla mobile app.
On the home screen, you'll see a lock/unlock icon. Tap it to toggle between locked and unlocked states.
Sub-step 3.3: Other Convenient Features Accessible with Your Phone Key
Beyond just locking and unlocking, your phone key (through the Tesla app) offers a plethora of features:
Remote Climate Control: Adjust the heating or air conditioning, or precondition your cabin before you even step inside.
Charging Information: Check your vehicle's charging status and estimated range from anywhere. You can even open or close the charge port remotely.

Remote Operations: Open the front trunk (frunk), rear trunk, flash the lights, or honk the horn to locate your vehicle.
Keyless Driving: Enable "Keyless Driving" directly from the app, useful if you've forgotten your PIN to Drive.
Summon and Autopark: For Teslas equipped with these features, your phone can initiate Summon to move your car in tight spaces or control Autopark.
Vent Windows: Crack your windows open remotely for ventilation.
