    Prius Gurus:

    Does anyone have the secret sauce programming instructions for a Prius Smartkey replacement for a 2007 model?

    My wife lost her unit and I bought a used one on E-Bay for about $65. Now I need to program it and the dealer said they want $165 to do so. OUTRAGEOUS! At least I saved on the cost of the unit itself which the dealer quoted at $202. I have the original key from the unit lost, just lost the main body unit off the key chain, so I will not need the key re-cut.

    Does anyone have instructions on how one can program the Smart-Key on their own without using a dealer?

    Thank you.

    You cannot program the smart key yourself. Find a dealer who will do so at the lowest price.

    Be advised that a key from a different model year will NOT work.

    I found a Toyota dealer here in Tempe AZ that programs the smart key for free. They also sell new ones for about $200 and program and key cut is included. Tempe Power Toyta autoloop drove 480-598-0000 They also had me come right in with no appointment. fantastic service.

    Well, folks, I'd like anyone's comments on my situation. Maybe I should have known about this. Maybe someone else will learn from this.

    I just found out that I need to have a my entire perfectly good computer replaced because I lost both of my smart keys (embarassing to admit) Dealership tried and tried to program new smart keys. I really do trust the dealership as it has an excellent reputation in this community ..have been family owned for years.

    Besides the hassle of having car towed to dealership. (gratefully, I have towing insurance) this is going to cost just under $1500.00. Needless to say my husband and I are in a state of "mini shock" and are looking for some humor or advice to pull us through. We are fairly low maintainence people in the emotional upkeep area, but we would be willing to have a "cyber pity party" if anyone would like to join us.

    Thank-you I do accept prayers.

    Perhaps you should call around to see if another nearby Toyota dealer can help. Note the reset mode mentioned below; from p. 05-2166 from the 2005 repair manual:

    REGISTRATION
    1. DESCRIPTION OF REGISTRATION
    HINT:


    Smart key codes are the same as recognition codes for the wireless transmitter. Registering a smart key code enables both the smart entry system and the wireless door lock control system to be operated.


    Code registration is necessary when the smart key ECU or smart key is replaced with a new one.

    (a) Select the operation mode from the following:





    New registration mode (when smart key ECU is replaced):

    Used when the smart key ECU is replaced with a new ECU.





    Add mode:

    Used when a new key is added.





    Re-registration mode:

    After using the erase mode to erase all smart key codes previously registered, use the re-registration mode to reenter them.





    Erasure mode:

    Used to erase all the key codes except for the code of the master key that is used during erasure mode. Use this mode when a key is lost.





    Reset mode:

    Used to reset all the key codes (including master key). Use this mode when all keys are lost.

    (b) Perform the code registration and the code erasure according to the flowcharts (see steps 2 and 3).
    HINT:
    Up to 5 master keys can be registered in the smart key ECU.
    (c) Register a new key number or change the key number according to the flowcharts (see steps 4 and 5). When the smart key ECU is replaced or all the key cylinders are replaced, be sure to register a new key number or change the key number in the smart key ECU.
    HINT:




    A key number is a 5-digit code stamped on the key number plate.




    Page 05-2170 provides the following detail about how to perform the reset procedure:

    5. RESET OF SMART KEY CODE
    HINT:

    This reset will take approximately 16 minutes to complete.

    Start
    Driver door is open.


    Hand-held tester operation:
    1. Select Prius from menu.
    2. Select SMART KEY.
    3. Select ID UTILITY.
    4. Select SMART CODE RESET.


    Perform the following;
    Read SEED NUMBER of tester screen and input it into TIS.


    Hand-held tester operation:
    1. Input PASS-CODE NUMBER sent from TIS according to tester screen.
    2. Make sure on tester screen that the registered codes are erased from the smart ECU.
    Finish reset

    yeah there trying to pull a scam i bet, in this situation they are supposed to contact a toyota rep and have them come over to the actual dealership

    try a different dealer

    try contacting toyota directly

    in the worst case scenerio and you need the ECU replaced, toyota has been known to share the cost with the car owners on a case by case basis, another good reason to try and contact toyota directly

    pardon my french but i'm really f*cking sick of hearing this crap. you have a 2007, i presume from your profile, so this applies to you. read it, make them call tech support, and save yourself $1500.

    Toyota TSB SS003-02 states that the passcode given by the Toyota Information System is only valid for 1 event.

    Questions :
    1) what happens if you lose your keys a second time?
    2) is it possible that the dealer botched the erasure process, making him responsible for replacing the ECU?

    how many tries do you get in entering the passcode?

    is it possible for the dealer to fry the ECU for entering bad codes?

    if you lose your keys again, DH is pretty sure that you just get a new seed number, submit that for a new passcode, etc.

    the process is handled through the scantool- if it does not get the proper authorization code, it stops the process. it leaves the ECU as is.

    most dealers have no clue about this process and sell a new ECU job, hence my irritation at people being charged several car payments' worth of cash for new car keys.

    Thank you to everyone for your helpful responses. I was unable to find the illistrated procedures for reprogramming keys that you refer to, galaxee. Could you guide me further? Also, tech support was consulted 2x. What is your response to this?

    This is a great place to gain information. Thank you again!

    their cluelessness does not mean you should pay $1500 for the job they do know how to do.

    post 24 in the thread i linked to contains the descriptions, but the pictures got moved to the bottom of that post in the last PC server change. i don't know how to relocate them to where they belong. if anything, you can show them the screens they should be using on their techstream tool with the pictures in there.

    today i was thinking what i would do if the dealer tried to stiff me with 1600 for the immobilizer, if i was in that situation i probably would tell them that i would either want toyota to split the cost or toyota to cover the item under warranty, and if that did not work, i would probably threaten to trade the car in, give it back, or threaten to leave it in the parking lot, and let it be repo'ed

    i don't think its fair that the consumer has to pay 1600.00 for something that can be just reprogrammed, especially if they only had the car for a year or so

    if the prius was leased i wouln't have those kind of options

    thanks. i have considered some of these options.

    i should clarify that the computer itself is just under $1000.00 and two keys are around $500.00 (programmed and cut). Even so, the computer replacement and cost is what was really troubling me.

    i'm so grateful for the comments and advice that i have recieved.
    it has helped a great deal to learn of other options.

    Hope to have good news tomorrow.:cheer2:

    Just bought a 2008 used and cannot find the "key number Plate." Just wondering if this is something the previous owner forgot to give me?? Thanks. E
