At first , you have to find a large car with a big engine to jump , that means the generator's power (Voltage) is at least larger than yours.
if not, the only thing you can do is to tow your car to the dealer ,you can not take out battery by yourself or something else, just due to lexus's special computering design refrained from car thief.

Good luck.
