2012 v (lowercase v for the Prius v wagon) Three Smart Key Problem

you may want to test your 12 volt battery. i think there's an ska shutoff in the programming, but i would think that would not allow you to start the car. check the o/m.

 

Isn't there some way to "reset" the fobs when they lose communication? I seem to remember seeing that in the manual somewhere. They should have a slow blinking LED when they are in contact with the car.

 

did you buy the car new? when did the fobs sks stop working?

 

You might want to check under your vehicle settings just to make sure something didn't get changed. I believe they are under Setup->Vehicle->Vehicle Customization on the touch screen.

If you don't find anything in there that fixes it, you might have the dealer check next time you are in. There are additional settings they have access to. Something may have just gotten flipped or reset.

FWIW unless its different than the '13 v3, there should be a small red LED just off the top left of the lock button that lights when you press the buttons. On the Gen2 at least the LED is a good indicator of the FOB battery health, as the LED gets too dim to see before the fob stops working.

Yes they do. Look for a little hole above the lock button, that's the LED. I think there may be different blink codes for different situations, but if you push the lock button it should flash. If not either the battery is bad or its busted. I can't remember where this stuff is at in the manual, but its there. Maybe in the section where it talks about replacing batteries.

 

Just checked my '12 v fob..

I just went to my garage. Locked the car from 5 feet away with the key fob lock button and the LED in the hole flashed. Walked back into the house maybe 30 feet away through a metal door to unlink the fob from the car sensor. When I went back into the garage and got to within 5 feet of the car I got a very short LED flash. I then grabbed the handle and the handle unlocked the drivers door.

Just so you have a base line of how it is supposed to work.

'12 v three

 

I just got finished changing the battery in my fob for my 2012 v (lowercase v for the Prius v, not an uppercase v) Three. The battery by the way is a CR 1632. I was surprised that mine went dead, when my wife's gets used way more.

Good advice to buy 2 batteries when you do it.

 

Are you just touching the slot and/or the handle ?
To unlock you have to grasp the handle, I believe the unlock sensor is on the back of the handle, to lock you touch the top or bottom of the handle (or both) all this without gloves on.
