    Prius forum,
    I had to replace the battery in my 2012 Prius c Two keyless remote and in
    the process it lost it's brain. It still works if I insert the key
    but needs to be re-programmed to work wireless. Can anyone give me
    the re-programming instructions?

    I suspect I touched a component and static electricity corrupted it.

    Yes I would think if they're cmos devices they would be static sensitive.

    I read lots of threads here about reprogramming a keyless remote but
    didn't really get a definitive answer. I also have searched the web
    with no success.

    steps to add 2009 Prius new remote/ key fob



    (Yes it Does for a 2009 Prius. Also BIG Thing: Have only the old remote and new or USED remote in the car. No Cell or Phone or Blue Tooth)


    1.Insert old fob into slot and remove it 4 times in a row, and insert it a fifth time but leave it in there!

    2.Open and close driver door 6 times.

    3.Remove old fob from slot. Car is in fob programming mode at this point.

    4.Insert new fob and leave in the slot for a full minute. Watch the blinking red anti-theft light on the dashboard. When it stops flashing and goes dark, your new fob is all set.

    5.After a minute, press the power once and open door, or vise-vera, Hey it worked for me, but only with the FOB inserted.

    6.Remove the new fob and you’re done. You should test both fobs to be sure they work properly.

    Now for the door lock functions.


    The Fob (for remotely unlocking/locking the doors)

    1.Open the driver door with no fob in slot and the driver door unlocked and opened. Other doors can be locked or unlocked, it doesn’t matter.

    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 both buttons on new fob simultaneously for a second and a half!. 11 Within 3 seconds, press only the lock symbol button. yes it does matter which!

    11.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. I don’t know how to troubleshoot that problem. Maybe just try again.

    12.To end this programming, open a door or put fob in the slot.

    13.Enjoy the savings from NOT buying a fob from the dealership!!!!!

    14.If you want metal keys, DO not buy them from e bay, they quoted me $7.92 CUT by them from dealer.
