So you can afford an 03 GS 300 but can't afford a key from the dealer? Sell the car and buy something you can afford to maintain instead of tryin to front.




Or you're lying and trying to figure out how to steal one ;)

Yeah, what ragseven said. and you should have got 4 keys with the car. I'm not toatally sure on it being an 03 but the older ones you could have a key made if you bring the VIN # and proof of ownership.

Is the immpbilizer/security light flashing when it cranks?  the first time it turned over, did it start for about 5 seconds and then die out?
no its jsut cranking. the engine immobilizer is wired directly into the ecm. you start this car, you would have to simulate the signal from the tranponder in the key.

Right, and i don't believe there's a way to do it. I've re-programmed a bunch of high end european imports for new keys, new ecms, etc and have never found a way to "pirate" a signal to get the car started. If there's a way, let me know. Just get the new ecm and keys if that's what you need.
