Thank you for trusting Just Answer with your Lexus question. What does it do when you try to start? Does it crank, try to start, then die? Watch the security light, what does it do when you insert the key.

It will not allow me to turn the key at all. I can not start the engine. Once I put the key into the ignition, the sreeting wheel and seat adjust automaticly.

This is not an immobiliser issue. This is a mechanical issue with your ignition cylinder. Have you tried turning the steering wheel as hard as you can in both directions while trying to turn the key?
