Pushed the Start Button while green but no start, no crank, nothing no noise. All the power is on. Scanned and got codes c1201, c1235

Found this on another thread, and seems the code is not related to your car not starting, rather than a brake problem.

So probably the car not starting is not throwing a code, I would check your battery health and then the starter to see if that is the problem.

Anyway, here is what I found on another thread:

"C1201 trouble code is common on lexus when the brake pads wear out and the the caliper pistons extends to maximum. It will cause the brake fluid to drop and the brake fluid level sensor is activated. Once the bake fluid level sensor is activated for more then 4 seconds, It will set the code C1201 in the system. Check the brake fluid if it is at minimum. Even though the light may not be on but when you go up / down hill it will illuminate for more than 4 seconds and that is what trigger the trouble code. By adding a little fluid and resetting the code you can prove that this may or may not be the probem. However to fix the problem , check and replace the brake pads as neccessary. Only then top up the fluid level to the maximum level , reset the trouble code and that should get rid of the trouble code till next brake job."

Yeah sounds like a bad starter, since the starter would still make some noise if it were a bad battery. Supposedly, you can get a bit more life out of a failing starter by whacking the starter motor with the end of a wood pole while someone holds down the start button
