There is a regular key in your smart key!
Crazy I know more about your keys than you do, I don't even have a smart key, I drive an SR5![]()
It's p 597 or so in my owners manual. You are correct that there is a small mechanical key inside the smart key. Originally I thought I might just carry that. I wish it were that simple. It unfortunately only opens the door. The mechanical key is not involved in starting the vehicle at all. There's a process where you touch the smart key to the engine start button and then press it. I'm guessing that even if the battery is dead there's a passive emitter of some type in the smart key that will work. Wish they'd have attached that to the mechanical key.
