Watt Key is a cutting-edge Wear OS application that transforms your smartwatch into a key fob for Tesla vehicles. Designed specifically for Tesla models with Bluetooth key functionality, including Model 3/Y and the refreshed Model S/X, this app offers seamless interaction with your vehicle directly from your wrist.

The application enables automatic locking and unlocking as you approach or leave your Tesla, manual control options, and access to various car functions such as opening the frunk and trunk. With quick-access tiles and support for summon features, Watt Key provides an immediate and reliable connection without requiring an internet link.

Optimized for Samsung Galaxy Watch 4 and newer models, along with Google Pixel Watch, Watt Key ensures top performance on compatible devices. It emphasizes security and privacy through end-to-end encryption and secure cryptographic keys stored only on your watch.

Watt Key stands out with its comprehensive feature set tailored for Tesla owners. The app leverages Bluetooth technology to connect directly to your Tesla, facilitating instant actions like automatic door unlocking/locking based on proximity, unlatching specific doors, and controlling the charge port.

Advanced functionalities include summon capabilities for forward and reverse movements, provided your Tesla has Enhanced Autopilot (EAP) or Full Self-Driving (FSD) features enabled. Users can also manually trigger commands via intuitive interface elements designed for ease of use on wearable devices.

Security is paramount; thus, Watt Key employs robust encryption methods ensuring that cryptographic keys used for vehicle authentication remain protected. These keys are securely stored on the user's watch and can be managed within both the app’s settings and Tesla’s native systems, offering peace of mind regarding data integrity and access control.
