Well, let me follow up with was found. The ignition would not turn in the cylinder. Had it towed to my mechanic who was unable to get it to rotate (though he broke my key trying). Ended up needing to cut the ignition out in order to remove the faulty cylinder. So I got to buy a new bracket (contains the cylinder), cylinder, and tamper resistant bolts. With labor (replacement and recoding) it cost just under $800. BTW, this was not a lexus dealer. Ouch!!
