When performing new registration of a digital key using the digital key application, the mobile device first communicates with the service center. Then, the vehicle communicates with the service center via the telematics system, then the digital key pairs with the vehicle via BLE.
If a registration malfunction occurs before the digital key has paired with the vehicle, it should be suspected that the cause is by misoperation of components outside of the vehicle, a telematics system malfunction, or a digital key ECU assembly malfunction.
If a registration malfunction occurs after the digital key has paired with the vehicle, it should be suspected that the cause is the communication system between the digital key ECU assembly and certification ECU (smart key ECU assembly), certification ECU (smart key ECU assembly) or digital key ECU assembly.
If a new share key cannot be registered, refer to Additional Key cannot be Registered (Share key).
Before performing troubleshooting of the vehicle, refer to Precautions for Inspection or Registration to check for a cause of the malfunction which is not related to vehicle settings or vehicle components.
Make sure that no DTCs are output. If any DTCs are output, proceed to Diagnostic Trouble Code Chart.
If the digital key system has been disabled, enable the system before performing troubleshooting.
Before replacing the certification ECU (smart key ECU assembly) or digital key ECU assembly, refer to Service Bulletin.
Registration of an owner key is possible when the following conditions are met:
The hybrid control system*1 or engine*2 is starting
The vehicle speed is 0 km/h (0 mph)
The smartphone is within the in-vehicle operating range
It is possible for the mobile device to establish a Bluetooth connection
It is possible for the mobile device to use the network
*1: for HV Model
*2: for Gasoline Model
Read the Data List according to the display on the GTS.
