I have an '07 Prius without a smart key fob. I understand that is fairly rare. Yesterday I inadvertently put the smart fob from my '04 into the '07. I immediately realized my error and changed fobs. Now the '07 fob won't start the car. The door locks and panic button work fine. The fob has a brand new battery. I tried disconnecting the 12 V and hybrid battery over night, hoping for a re-set. It didn't work. I've tried various tactics after watching videos about the "chicken dance" methods. Nada. any sure-fire methods? Is it that simple to screw up the immobilizer circuit?
No I wouldn't think so something seems amiss if I put my non SKS remote in my SKS 09 car nada with that remote on seat of same car inserting correct remote in car only not slot car readies imed. ? Slot is amplifier it amplifies the signal from you're remote wether correct remote or not I no think it cares. This should be reflected by red car on dash going out w correct remote?
I don't think I'd be chicken dancing just yet but eh. Is the red car flashing imobiliser flash . Do it stop inserted? Is the slot wonky do remote lock into slot ?
I agree with Tom, I have done the same thing and the car READYed immediately after the correct fob was put in the slot. Are you 100% sure you are using the correct (black logo on the back) fob in the slot of the '07? Do you have any body ECU codes? They start with Bxxxx?
Iooking at factory manual . Good rabbit hole for sure . It would mite be more to story once discovered .
Since I only have one fob for this recently acquired '07, yup it's the right one and it worked 3 days ago just fine. I only had the problem after inserting the wrong fob, very briefly inserted. Since I can't turn the car on, my code scanner won't connect...I did try. I live two hours from the nearest Toyota shop and I can't just pop in there easily...So far, I've been able to work on my '04 and repair the hybrid battery and replace the inverter, various water pump, etc. I've only worked on cars for 57 yrs..
Well you're a little older than I am so I'm pretty sure you gonna get it . I just cannot duplicate issue here w 4 gen2 running here and a full stocked shop area . I tried a bit yesterday . I've remotes apart and cars w plastics off showing all the pertinent stuff . Interesting for sure . And you haven't had this remote apart to put new case on etc . Very interesting and red light stays indicating imobiliser is in play? Seems like certification issue or such . But why .
Take the battery out of the fob and then insert it into the slot. I've seen some weird things happen. I've also seen those weird things cured by using a battery-less fob. I don't know if it causes some kind of reset or what. This also cures the problem of an SKS car that has a non functioning combination meter and won't let you turn the car off. Just use a fob with no battery. Car will work completely normal again using the fob and slot.
