if your a Toyota tech then you must know of the campaign we had on certain models with the steering mogul under the dash on the steering shaft housing and if there is the same campaign on that particular Lexus I really don't know my friend but worth looking into I just retired from being a Toyota master tech this Feb and no longer have accessibility to that info. If they do that would explain why you can't program it. Perhaps Ill opt out so maybe another expert with more Lexus experience may be able to assist you better. good luck.
