same thing here
Part was $700 CAD and 1.5 hours to install. New cylinder and some bracket....
Stranded me withg accessories on, killed my battery, had to tow.
Ignition cylinder broken, turns out, there is a weak internal rod that can eventually break. Heres a description I got somewhere when I was doing some research for the fix. I didnt have time to play around so I just got it fixed and paid whatever it costs.
They had to reprogram a new key so I got a spare key out of the deal, yeah big deal...
Anyhow, here are some other details, Im not sure which site I got this from because I cut it and pasted it to my email...

Today, when I went to start my car, the ignition switch broke! The steering wheel adjusts like normal, but the key rotates left and right without any resistance and it's stuck in accessory mode. I'm assuming that I need to have the entire ignition switch replaced, but I thought I'd ask to see if anyone else has any experience with this. I haven't taken it apart yet, but my past experience with ignition switches in other cars is that there is no easy to way to repair them. Assuming that I need to replace it, is there a way to order one that is keyed for my car's existing set of keys? Thanks in advance!

Update: I got the switch fixed.
Here's what I did, so hopefully this will help the next poor soul that experiences this.
First off, my diagnosis was incorrect. The actual key tumbler cartridge was perfectly fine. The problem was with the cast aluminum rod that the key rotates to activate the various switches that operate the car. That rod is about 6 inches long and has several cams on it, a brass spring loaded blade that plugs into the key tumbler cartridge and a keyed end that plugs into a round shaped switch that has the spring inside it. In my case, the rod had an interal defect that caused it to have a weak spot and it snapped in half. Note to Lexus/Toyota: This is a poor design! This problem is due to poor engineering design. There is no excuse for using a cheap cast part rather than a machined part. I spent much time and effort attempting to order a new rod from Lexus and Toyota and finally determined that it is impossible to order this indivual part. They want to sell you the entire ignition switch assembly for over $800 and if you plan to do that, I recommend you spend another $600 to have it installed. You need special tools to remove the ignition switch assembly from the steering column and this is not a job for the feint of heart.
