i have a rx300, year 2000. i have lost all my keys except for a silver flat key with a key code that will work the doors, glove box, and start up the car but the motor won't turn over.

i do not want to pay $700 for a new key at the lexus dealership. Any suggestions? I am a little frantic.

If you don't have a master, then Lexus can't program it (at least we don't). You would have to get a master key and get the computer flashed by a local locksmith that has the equipment. I think the company around here charges $300 to flash. Plus whatever the key is. Any key that starts the car has a chip in it that is programmed to the car. That's why that silver wallet key won't. If you have the black, flat wallet card that holds the silver key, you can hold that up to the key and the car should start. There should be a chip in it. And I believe the wallet card is programmed as a master so they may be able to use that to program another key without flashing.
