this sounds like the key fob has become out of sync with the car

If its a push button start 1st try pressing the metal lexus sign on the key fob against the metal outer ring of the starter button

this should turn the ignition on and resync the fob

if that doesn't work then you'll need the Lexus dealer to reset the 'proximity' computer

this will then allow keys to be accepted into range of the car receiver
