デジタルキー is an app developed by TOYOTA MOTOR CORPORATION that allows users to connect their smartphones with digital key-compatible Toyota, Lexus, and other car models. With this app, your smartphone becomes the key to your car. You can easily share your car key with family and friends using your smartphone. Whether you are together or apart, you can share the key through QR code scanning or SMS. The app also offers convenient features like specifying the duration of key sharing and limiting the functions that can be accessed. For example, you can lend your car temporarily to a family member or provide a key that only allows door lock and unlock operations to a friend without a driver's license.

Please note that it is recommended to always carry your car key in case the digital key is unavailable.

For more detailed instructions on how to use the digital key, refer to the official website.

Before using the app, certain preparations are required depending on whether you are the owner of the car or a shared user. Owners need to register for a TOYOTA/LEXUS common ID, have a T-Connect or G-Link subscription, and sign a digital key usage contract. Shared users need to register for a TOYOTA/LEXUS common ID.

The app is compatible with iOS 14 and iOS 15, and it has been tested on smartphones. Please check the official website for a list of compatible devices.

Please note that the app may not function properly on certain smartphone models and is not optimized for tablet devices.
