If you don't have the correct code then you need to take it to Lexus and let them do it. It should only be around 50-100 dollars for unlocking and new code...or just buy a new system

I have read this 6 times and still not sure what the issue is? I have a 2005 ES330. To open all the doors with the key fob, you have to double press the Unlock Button. Pressing the Unlock button once, only opens the driver door.
The door lock module and further help is in the link.
sounds like an engine immobilizer problem. close all doors,hood & trunk completely. lock and unlock the car three times with remote, then put key in door lock and lock & unlock three times.
did you accidently try to start with wrong key?
this is a computer problem. 91-96 lexus ls400 are known for having their computers go out on them. I would have never believed it but my ls400 did the same thing. I sent the computer to Auto Computer Exchange in Davie FL. They reprogramed it for $310 sent it back to me in a day. It fixed the car. I have had no problems out of the car. I now work on ls400 on the side to fix the same problem for other people.
are you sure the battery is good in the remote? if so try putting the key in the driver door lock and locking and unlocking the doors three times in a row. if this dosent work i suggest taking it to an experienced lexus shop.
YOU WILL NEED THE RADIO CODE.. If you dont have the code you may call the dealer with your vin number, or the radio serial number. it may be in the owners manual, sometimes I write them on the owners manual in case the card gets lost, may look like a credit card.
