Update. Have changed ignition switch, but the fault it appears is with the steering lock ... and it is a sealed unit which will cost £2000+ for Lexus to replace. Car is in a tight space, cannot be lifted or moved so I'm stuffed for the moment.

Thank you Herbs and George for your comments and advice. Have tried your method George without success, as did the AA. Have ordered replacement ignition switch. Will update next week.

I have owned this 2001 LS430 for a year. Have been using with new battery a month old without issues. The ignition switch has been wonky since purchase and now does not turn: it will not turn from ‘lock’ to ‘acc’ either on key or smart access. The steering lock is now on as well. AA patrolman tried to help with no luck. Code reader needs ‘acc’ on to function. Have replaced new battery in keyfob. Other keyfob not turning either. The alarm light is off when key inserted, the steering wheel moves out but that is all. Any suggestions gratefully received...
