- 03
Select Digital Key in the app and complete the guided enrollment process.
- 04
Keep the electronic key nearby while confirming that the phone can lock, unlock and start the hybrid system.
Important limits
- Digital Key needs a charged phone and phone-to-server communication, and is disabled when the smart-access system is disabled.
- A phone used alone does not provide every electronic-key feature, including certain approach lighting and power-back-door walk-away functions.
Quick checks.
- ✓If enrollment is unavailable, confirm the RX is registered to the correct Lexus profile and the required Remote Services subscription is active.
- ✓If the phone stops working, restore its connection, charge it and use the electronic key; contact Lexus promptly if the phone is lost or stolen.
