2007 toyota fielder

has anyone done any of these, it's the new body style, with pushbutton ignition, what bypass would you reccomend, also any ideas on how a second RFID key can be programmed to this vehicle.

any thoughts on the rfid tag programming

ok, i had to dig this post up cuz i didn't wanna restart a new one, the customer says, the bateries in the tag died, and upon replacing them, the pushbutton ignition would no longer respond, so i don't have access to an owner's manual. any suggestions on what can be done, does the system have a failsafe?

Anyone, there has to be some sort of failsafe procedure, for this situation, i highly doubt toyota would make the system without it, has anyone ever had this problem, i really am counting on the experienced guys here, since locally, there aren't many people who care to learn about the systems, and info is limited, since i don't have alot of experience on these ignition sytems myself, they are fairly new to my market, so any help as to regards what can be done would be highly appreciated, thanks in advance.
