Couldn't tell you what is wrong with the ignition, but I can confirm that if you replace it, the original key will still work in the doors.
My husband took it apart and the ignition cylinder seems to be working okay but the mechanics beyond that to the steering column seem to be broken. :( How do the mechanics inside get broken like that? Old age? I think I am really wanting to sell this car. I realized that when we bought it, there might be some up keep on it because of its age, but man, new ignition parts, new a/c drier and compressor, new alternator, new battery, new brakes. I keep telling myself after each one, okay, all should be okay now. lol Then 1-2 months later something else needs repaired. I think it needs new shocks now too because in the rear if we hit ANY dip in the road the rear tire well comes down on the wheel. OUCH! :o Anyone interested in buying a silver 1990 LS400 with approx. 180K miles on it? :D
