look in the manual or at the sides of your door, there's an sticker witha lot of numbers, im not sure if its at the door but that sticker must be at any place of the passenger side or on the car.
the sticker has lots of numbers, there are all the codes of the car
look at your manual or at lexus dealership, if your car its not new they know which its the code
hope this assist you
