You could have a bad key or something related to reading the key has a problem. Isn't a 2016 Lexus still under factory warranty?

The engine's computer is encoded to the transponder key & ignition sensor and theft module ECU, if you replaced the engine's computer it will need to be re-encoded to those other components, most likely this will have to be done at the dealership.
