Thanks for the solution guys.
...I made another dum dum (or the car did?)
I had it jacked up and the battery disconnected while I was doing some work. Nothing electrical was touched just felt it was best practice to disconnect it.
after I was done i reconnected the battery and now I get the turn signals on all 4 sides and some other (DRL maybe?) flashing like I have my 4 ways on, in addition the backlighting for the AC controls and radio is pulsing with them, and the security light flashes too (3-4 flashes then stops for a few seconds, repeat). the car will not start (no crank)
what the hell did i do? I called two lexus dealerships and they suggested checking all the fuses, which I did. nothing. Did the immobilizer reset (key in lock, close all doors/trunk/hood, wait, unlock door with key) to no avail.
