Welcome to Club Lexus.

We're going to need more info to begin to help you. Year, miles on car, last service...any dash lights...etc. First place is to read any codes stored in the ECU.

Still not enough info. When was the last time the car started and what exactly does it do when you turn the key to start it?

Not likely. If it runs for a few seconds then dies, it is another area. No codes leads me to suspect an ECU but there are still other areas to work through.

How did the car run prior?
