You may have to get your vehicle's DCM (Data Communication Module) updated for it to start your vehicle. This is likely because some vehicles used 3G as the original communication platform but this 3G wireless mobile telecommunications technology was discontinued. So, now a DCM update is needed from Lexus at no-charge. This has to be done at a Lexus dealership's service department.

The My Lexus app with Remote Start is available for 2015 and newer per below image.
I got my DCM updated (initialized) this morning so there is now a handshake communication for both the key fob and the 'My Lexus' app with the Remote Start feature. Both work flawlessly to remote start my 2018 GS 450h!
