About Phone & Watch Key

- Works on iPhone, Apple Watch, Android and Wear OS
- Supports Tesla Model 3/Y, 2021+ Model S/X, Cybertruck and Semi
How to enable Phone & Watch Key
- Phone app: Tap the key icon on the home screen
- Watch app: Tap Watch Key
Using multiple keys
- Apple devices: You can use both Tesla and Tessie Phone/Watch Keys at the same time. Only one will appear as connected in the vehicle, even when both are active.
- Android devices: Avoid using both Tesla and Tessie Phone Keys simultaneously. Most Android devices limit Bluetooth connections, which can cause interference as both apps compete to connect.
How to unpair Phone or Watch Key
- On your vehicle touchscreen, tap Locks
- Tap the delete icon next to the key
- Bring your phone or watch near the vehicle and the pairing will be reset
If unpairing doesn't work:
- Make sure you’re inside the vehicle
- Ensure fewer than 3 keys are currently connected
How Auto Unlock and Walk Away Lock work
Your Tesla locks and unlocks based on the signal strength of your device. Some devices with weaker Bluetooth signals may need to be closer to the driver door to connect and unlock.
Apple Watch support
- Series 6 or newer, watchOS 9+: Supports background Auto Unlock and Walk Away Lock
- Older models: The app must be open for Auto Unlock and Walk Away Lock to work
To conserve battery, Apple limits background unlocks when the app is closed to a few times per day. Opening the app resets this limit.
