I have a 2007 Lexus IS250 AWD. It looks like it is deprogrammed that's all I can tell. after a week parked, I come back and nothing works. I can only lock and unlock the car, my dashboard does not light up, nor does the radio. I tried to change the power supply module, the dashboard lit up then it went out I don't know what to do anymore

Welcome Tiemcani, what year and model Lexus do you have?

This specific area of our forum isn't the right place for your question, I'll move it where it needs to go once you provide that information.

2007 Lexus iS250 AWD

I assume it was working before you parked it for a week. Did you check the battery?

I even bought a brand new battery. All the lights work, inside and out. We checked all the fuses.

Have you tried to get the codes read to see if there are any indications of what is wrong?

I can't read the codes because the dashboard doesn't light up, it's like there's no electricity getting to the dashboard.
