    If you don't have one smart key, you'll have to buy a new one from Toyota and have them program the car to use it. Toyota will only perform programming if the part is genuine Toyota. I've been told for the no key case that means they will have to do what they call a reset of the Smart Key ECU. Resetting takes a while and is not cheap, depending on your Toyota Dealer's service department.

    You can also check with a few authorized auto locksmiths and see if they will sell a Smart Key and / or program the car for it and what their price is. Make sure they understand you are in the "no key" situation.

    Expect around $157 for a new genuine Smart Key with the physical blank key, part number 89994-47061, from a Toyota Dealer's online store.
    Call several Dealers to get a price for programming without a working Smart Key.

    Thank you so much that really did help alot. secondary question, so say i want to just buy the smart key and only use the actual physical key to get in and out of the car for the time being until i actually take it to the dealer so they can program it and all, where would i be able to cut the actual key with the "no key situation".

    The dealer will need to do a reseed of the car. It will wipe out all the keys stored in memory and program a new one into the car.

    You can use either new keyfobs or used keyfobs when they do a reseed.

    To get the little metal key cut, the dealer can probably look up that info with your vin number

    JC is correct on all points. I posted the following somewhere I can't find right now, so here it is again.

    Dealers can cut a new key from the VIN. You'll need proof of ownership such as registration and/or title along with your drivers license. The registration and/or title must match your drivers license. A family member or friend cannot get the key for you.

    I had a Toyota dealer do this very thing in Feb. 2018. The Smart Key remote and the key in the remote was from another car. The car / remote had been programmed and fully works, but I didn't have a working physical key. The dealer took a day to get the little blank key that plugs into the remote: P/N 69515-47010, $19 list price.
    They had it priced at $23, but they gave me a discount so it ended up about $20. Cutting it is included in the price. I had already bought a third party blank of this key for $5 but they will not cut that. They will only cut Toyota parts.

    The little remote key wouldn't work to the right at first so they made me a standard size key for free to try to get it to work. It finally turned to the right with more force from the standard key. Then the little remote key worked after that.
    The door lock needed to be lubricated since it hadn't been used much. At first, it would turn left to lock but not right to unlock. The standard size key got it going. I put some dry / Teflon type lubricant on it later.

    The standard size key blank code is TR47. I keep that one in my wallet since it is nice and flat, and I can at least get in the car if I lose the remote.

    I believe it should be a standard Toyota key, maybe Home Depot would have it. Keep it in your key ring for when you need it.
