Hello, everyone. Vehicle is a 2001 LX470 with 167,832 miles.
When turning the key in the ignition, I felt something snap and the key turned freely in the ignition lock cylinder. After searching in this forum, I figured it was probably the steering column bracket barrel rod that broke. My circumstances did not allow me to tackle the repair myself, so I took it to my local Lexus dealer. The parts guy and service advisor have seen this prior and a new bracket assembly and breakaway bolts were ordered. The experienced service advisor is no longer with them and a not-very-experienced advisor checked me in. Long story short, they repaired the problem (broken barrel rod) and the vehicle starts and runs fine. I was told, since the job took a week, that the tech was not experienced with this repair and the service manager had to help him. All of this leads up to a new set of problems.
These are the issues I observed upon picking up my Lexus. None of these issues were present when I brought the car in for service.
The immobilizer light no longer blinks prior to putting the key into the ignition or after removing the key from the ignition.
The driver‘s door chimes constantly when open, even when the key is out of the ignition and the headlights are off.
The door locks are not operational from inside the car, either by pressing the switch or moving them manually. They spasm if operated. The only way I can lock the car doors is to lock them from the outside with the key.
The automatic tilt steering column does not function when the key is put into the ignition or removed from the ignition.
The AHC indicator lights are always on (low position) and the AHC check light flashes constantly. The AHC was removed from the vehicle four years ago by Slee Offroad and those lights have never been illuminated since. The AHC relay in the fuse box was removed by Slee, so I suspect something done in the cabin is causing these lights to be illuminated.
I think I understand the basics of how the immobilizer and ignition lock cylinder and associated hardware function but am far from an expert.
I am taking it back to them tomorrow to have them correct their errors. I look forward to hearing your analysis and suggestions to resolve these issues. Thank you in advance.
 
Take it back to Dealership, or look under dash for wire housing block(s) unplugged. Also check fuses.

Personally. I disconnect neg, clamp from battery post, before touching anything electrical.
 
Thank you 2001LC for your timely recommendations. I took it back to the dealer this morning and had a lengthy, honest, and productive conversation with the Service Advisor. He is going to have the shop foreman and their diagnostics expert look at my rig. I feel like it’s in good hands now. I showed him your reply and he wrote it down. I will report results later after I receive it back from the dealer.
 
I received my Lexus back and had a great conversation with the customer care manager and a highly qualified Technician who demonstrated that everything was now working correctly. 2001LC was pretty much correct. A module connector was left unplugged (perhaps the key sense transmitter?) and the ignition lock cylinder was improperly installed. It just goes to show how important the fundamentals are!
 
Glad it all worked out in the end… hopefully they gave you a free oil change or detail for your troubles!
 
They detailed it but that was because the first Technician that screwed things up did not use protective covers on my seat covers and got them filthy, as well as not covering the center console and covering it with grit and metal shavings from grinding and drilling out the breakaway bolts.
However, I did help myself to several good cups of coffee from the machine during my visits, as well as plenty of tasty snacks for my grandson and me.
It’s good to have my rig back and to have everything working well again.
For those that have a wobbly automatic tilt steering column, I had provided new Toyota/Lexus copper bushings and they installed those for free. My steering column play feels like it’s new again.
 
As the saying goes, “All is well that ends well!”
