I had this strange problem, which occurred twice already - rav4 engine doesn't start, but battery is good. When it happened the first time, removing and inserting the ignition key helped. But the second time, the only thing that made the engine start was ... pushing the panic button on the key. It smells like a problem with immobilizer chip in the key, though the whole procedure with panic mode (found just by chance) is quite weird. Besides it happened twice only with 3 months interval (if the key is damaged, I'd expect more consistent failures). Had anybody experienced anything like this?
