My Lexus IS250 will not start. It has power but car won't turn over. It has been at a repair shop for 3 weeks and it seems that the problem, which had happened once before, is that the immobilizer has been activated. and is shutting off the engine. Might there be someone available who has experience with disabling, resetting or other a Lexus immobilizer? Will pay for work of course, car is at a repair shop on Federal in north Pompano.
