I just bought a 2006 Sienna - didn't pick it up yet. It comes with two master keys and keyless entry transmitters and one valet key.
About how much do spare keys cost? What about a spare transmitter? Can a locksmith copy these keys or must I get it from Toyota?
I want to carry around a spare key for the door in case I lock myself out. Is there a separate key for the ignition and doors as in older cars or is everything on one key in the Sienna? Can a locksmith duplicate the key such that it will work to open the doors even if it won't start the car?
I know that GM cars have keys with resistors in them and the resistor is necessary to start the car but a plain copy will serve as an emergency door key. Do Toyota keys work the same way?
