HI guys
I just bought a silver 2004 ls430 with 90k on it. It Only come with 1 smart key but none of the buttons on the key work. I had replaced the battery on the key, still nothing works. I had turn on the smart switch under the dash and the green light is flashing. No luck. I'd try to turn on the engine with the key in my pockeT It shown a message the smart key is not detected. Anyone have any inputs on these matters is greatly appreciated.

Double check the system is enabled. There is a button by the gas pedal. The button for the smart key and a **** for alarm volume. Make sure the button is depressed. Programming is done thought the dealer software - Toyota Techstream.
