    I bought a used 2004 prius. It only has 1 key fob. I've been looking around it's it's so insanely confusing. My biggest issue is cost. I want to find the cheapest backup key possible. So do I go with...

    Key fob... or....transponder key??

    Can a transponder key be used to do the chicken dance to reprogram another new key (lets say if you lost your main key, are down to just that transponder key and now you want to create a new key again?) A transponder key is also a lot cheaper than the keyfob. so I was thinking this might be a good option.

    Also on ebay they sell all kinds of crap. So a new key fob is 100. But I was thinking about maybe buying a used keyfob, which would save a lot. But would I be able to reprogram that used keyfob doing the chicken dance? Or does it have to be a brand new factory key fob? And will it reprogram (with chickendance) without needing to have the dealership do anything? Or do they have to do something also?

    I just want a cheap back up key. This is so ridiculous. You have to be nasa rocket scientist to figure out all this crap. It's so frustrating!

    I am sure there is a key that could be programmed. I don't know enough about the architecture of the keys themselves, but chances are, you will need a key that has smart key functionality. Do you just want a key that will unlock the door?

    While it may not the cheapest way initially, purchasing a new fob and following the chicken dance routine will most likely be the cheapest way in the end. If you have the smart key function (chrome logo on the back of your fob) you will need a smart key fob to retain full functionality of the smart key system. This is Toyota's offering at the time regarding anti-theft its just part of ownership in today's society.

    Agreed. For all the trouble these cars DON'T have, it is a small price to pay.

    The "Chicken Dance" is outlined here : How to Program a New Key Fob for Full SKS Functionality | PriusChat
    and here :


    I purchased a new smart key off of Amazon for $100 and it programmed on the first try. Search for "
    Genuine Toyota 89994-47061 Electrical Transmitter" assuming you have Smart Key. If not, the part number will be different.

    I bought a legit, new fob from a FL dealer through Amazon (they also sell on eBay, I believe) for around $100 (SKS) and did the chicken dance myself. I think that's the best route. In the event that you do lose your current fob, I would bet you're going to want an identical one to replace it.

    I bought mine from the same Florida dealer off Amazon. No issues.

    I got a new fob (on ebay) last year and did the chicken dance. The fob works but I could get it to unlock the doors. Any trick on getting it to work using the chicken dance method?

    Chicken Dance with Minor Revisions to Make it More User Friendly (I hope)

    PROCEDURE A
    This procedure (steps 1. through 5.) is to be used for both the black and chrome logo key fob. This will program the fob to Start/stop engine while it is inserted into the key port. All new fobs should be programmed for this regardless of logo or SKS functionality (SKS=Ability to drive the car with fob in your purse or pocket, not in the dash slot).

    You can copy all of this text onto your clipboard and then paste it into your word processing program to print it out.
    -------------------
    1. Get into the car, close and unlock all doors and ensure the car is off
    2. Insert old fob (your fob that currently works) into slot and remove it 4 times in a row fairly quickly, and insert it a fifth time but leave it in there!
    2. Open and close driver door 6 times fairly quickly.
    3. Remove old fob from slot. You hope that car is in programming mode at this point, which will be indicated by the red car-shaped dash light staying on and not blinking.

    A. If red dash light is NOT on solid: you failed to get into programming mode. Go back to step 1 and try the procedure at a different pace (faster or slower)

    B. If light is on solid, proceed to step 4.


    4. Insert new fob and leave in the slot. Watch the blinking red anti-theft light on the dashboard. When it stops flashing and goes dark, your new fob is all set. This may take up to a full minute.
    5. Remove the new fob and you're done with the START/STOP portion of programming ( if you have SKS, proceed to PROCEDURE B don't have SKS, proceed to PROCEDURE C).

    PROCEDURE B
    This procedure (steps 1. through 10.) is for chrome logo key fobs and vehicles with SKS functionality

    Lock/unlock doors remotely + SMART KEY functionality
    --------------------
    1. Open the driver door and leave it open with no fob in slot (ensure the driver door is unlocked). Other doors can be locked or unlocked, it doesn't matter.
    Complete step 2 within 5 seconds
    2. Insert old fob into slot and remove it twice.
    Complete steps 3. and 4. within 40 seconds of completing step 2.

    3. Close and open driver door twice.
    4. Insert and remove old fob once.
    Complete steps 5., 6., 7. and 8. within 40 seconds of completing step 4.
    5. Close and open driver door twice again.
    6. Insert old fob in slot and close door.
    7. Without pressing the brake, press power button, wait a second, press it again, wait a second, press it a third time to turn car back off.
    8. Remove old fob from slot. You'll be in "add mode" at this point. Within 3 seconds, the car should lock and unlock doors to verify it is in add mode. (the precise number of times the car locks/unlocks the door is model specific - but it should do it at least once). If it does not cycle the locks, return to step 1. otherwise proceed to step 9.

    Steps 9.a. and 9.b. should be started within 40 seconds of completing step 8.
    9a: Press and hold the Lock and Unlock key (simultaneously) on the OLD/MASTER fob. (a couple of seconds should pass and the locks will cycle once. If you do not get this cycle, it is likely due to a weak CR 2032 battery in your fob. Replace the battery in your old fob and try again).
    9b: Press both the Lock and Unlock key (simultaneously) on the NEW fob. Hold for about 1.5 seconds then immediately (within 3 seconds)..
    9c: press the lock key on the NEW fob. If successful the lock/unlock will cycle once indicating success (It may take a while for the lock/unlock cycle. I've seen it happen just as I was ready to say, "well, it didn't work". If you wait for a long time (a long time being more than a minute) and get no cycle at all, complete step 10. and test to see if the SKS functions of your new fob work. Remember to put old fob outside the car or else test of whether new smart key can start the car without being in slot in dash would be meaningless).


    Several users have reported it being necessary to execute 9b step twice before doing 9c, but most do not find this to be true. If your first go-around does not succeed , try it again and execute step 9b twice then 9c. You may be able to just do it over from 9a onward if your car is still in “add” mode, rather than going all the way back to step 1 of Part B.



    9d. - If you need or want to program another "new" fob, repeat steps 9. a. 9.b. and 9.c. for the next new fob. If done programming fobs, proceed to step 10.


    10. To end this programming, open then close the driver's door.



    To test whether you have successfully programmed SKS mode, put the old fob outside the car and close the door, then try to start the car without putting the fob in the slot.

    PROCEDURE C
    This procedure (steps 1. through 13.) is for black logo key fobs and vehicles without SKS functionality

    1. Open the driver door with no fob in slot and the doors unlocked.
    2. Insert old fob into slot and remove it twice within 5 seconds.
    3. Close and open driver door twice.
    4. Insert and remove old fob once.
    5. Close and open driver door twice again.
    6. Insert old fob in slot and close door.
    7. Without pressing the brake, press power button, wait a second, press it again, wait a second, press it a third time to turn car back off.
    8. Remove old fob from slot. You'll be in "add mode" at this point.
    9. Car should lock and unlock doors twice to verify it is in add mode.
    10. Press and hold both buttons on new fob simultaneously for a second and a half.
    11. Within 3 seconds, press just the lock button on new fob.
    12. Car should respond with one quick lock/unlock to verify that the new fob is all set. If the car responds with two lock/unlocks, that means it didn't work. Either try again, your fob is bad or, you have too many fobs assigned to the car.
    13. To end this programming, open then close the driver's door or put fob in the slot.


    Here are the part #'s for the fobs:
    OEM Fob Part # for smart access is 89994-47061
    OEM Fob Part # for non-smart access is 89070-47180.

    PS: Practice these steps first (dry run).
