Prius (2010-12) :: Key Not Detected Message When Try To Start With Single FOB
Oct 23, 2011
After last maintenance at dealer where I got my Prius. I get two or three times of "Key not Detected" message per week when I try to start the car. I have to push start button several times for the car to detect key and start up properly. However, I don't have issue to unlock door by placing hand on the sensor and enter driver's seat. Where to start? I thought it was battery issue, but that wouldn't explain why I don't have any issue unlocking the driver door by placing hand on the sensor, which I always do before I push the start button.

I got this message today, twice as I was pulling out of the driveway but it went away both times. After the 1st I stopped and pulled the key out of my purse. It came back on a 3rd time and right as I was trying to determine if it was significant enough to pullover when the hood flew up and hit the windshield. The hood was closed and there were no other messages.

While driving the key not detected message appeared three different times during a 50 mile trip. The message lasted approx. 30 seconds.

I've had this happen twice now. I got my gen3 in October 09' and lately the car has said the key wasn't present though it was sitting on the passenger seat. I had to put the fob up to the start button just to get my car started.

The car beeped at me when I tried to lock it. Initially, I thought I forgot to turn it off. But no, it said "keys detected inside". Not so, as the key was in my pocket outside when I tried to lock it and the other key was 10 miles away at home.

I had a Samsung Galaxy s4 that gave me the message tethering detected and then the only way to get my phone to connect via bluetooth again was to delete the phone from the car and reestablish the connection which only worked until the signal popped up again. I called US Cellular and they thought it was the phone so I chose to get a refurbished s4 over having work done on my phone. I had that phone hooked up and working well for about 1 month and now the second phone is doing it.
The message last popped up while I was in my office across the street from the Prius. I'm guessing it's either a s4 issue or a US Cellular issue being it happens in and out of the car, but US Cellular is convinced it's my car. I'm thinking about switching to an iPhone because this is only one of the many things I hate about Samsung galaxies.

Is this a bug? I hit the start button, everything comes on, put on my seatbelt, etc... then I shift into reverse (out of park) and it says I must start in park. But it's already started. I then have to hit the start button to turn everything off, then hit it again to turn anything on. How to avoid this?

Just bought a 2010 Hertz GenIII w/44,000mi. Wife had trouble starting it twice with weird messages like place car on flat surface to orange triangle. I hear it may be a weak battery???

There have been a couple of incidents where the key fob has not been detected by the car, even though it is in the car. When it did this, I also noted the unlock button on the fob didn't work. It only does it a couple of times then all of a sudden it seems to work. There is no message for a low battery (it's not that old).

My key fob works at a distance to lock the car. Inside it is not recognized. Changed battery recently?

unlike a lot of my fellow prii folks, i love the beeps. My favorite one is the confirmation of locking the doors by touch of handle and also unlocking by touch. Believe it or not i even like the backup beep which is kind of like a nice confirmation of "yo, dude! we are going backwards" but the most important one for me is the long single loud beep. happened the other day when i got out of my car to get a coke and the car emitted a continuous loud shrill beep as i started to walk away. I was still in drive.

I have a 2011 Prius Three. After about a month of owning it, I had the dealer disable the back-up beeping so it only beeps once when backing. I'd like to disable the "key not detected" beep.

I bought a Prius persona in 2013 brand-new and in about a year or year and a half later start slowly coming noises from interior plastics and now it's a 2 1/2-year-old car and I have noises from every single plastic that's in the interior. $29,000 car and two years 2 1/2 years after it's just annoying and embarrassing for Toyota. Dealership is refusing to do anything because I'm over 36,000 miles and the warranty that I bought originally with the car is refusing to do anything too. And the dealership wants to charge me per hour just to start and it could take up to the whole day or two days or half a day and it could cost me thousands of dollars on a $29,000 car is two years old, unbelievable.

About 3 weeks ago our Gen III (Prius III with Nav and Solar) began generating a single standard duration (maybe 1 second, similar duration to reverse beep) beep each time the driver's door is opened. It only occurs with the driver's door and happens whether the car is locked, unlocked, started or not. We had our reverse beep-beep converted to a single beep about 2 months ago and now this single beep is annoying each time we open the driver's door whether we are inside our outside of the car. We could not find anything in the user manual that described why this beep would continue occurring.

I changed the battery in my key fob recently. Since then the car has randomly given me "key not detected" signals. At these times, the door lock/unlock buttons don't work either.
When it does, I open it and push the battery around, trying to make it connect, close the fob back up, and it works for some apparently random amount of time. So my best guess it that there's a loose connection to the battery.
If so, have you found a cure, such as the right place to wedge in something small to make the connection secure? Anything else?

Last week as I was returning home I had a strange event in my Prius. I was coasting at about 30 mph when I heard a very faint pop sound a bit like a balloon breaking. It sounded like it came from the right rear area of the car. Afterwards I thought I detected a very faint chemical smell. Could this have been something involving the HV battery?

We have a new 2015 Prius with 6k on it and we are noticing one solid brief single click when the brake pedal is pressed and/or released. It doesn't happen every time (just some of the time) but it is only noticeable at slow speeds.

I am new to the prius 2010.
I filled up last week and I noticed that as soon as a single cell display in the fuel display part has some empty section like 3/4 fuel(single cell) the next day or after that that whole cell disappears without it showing that single cell as being empty.
Around which fuel cell, when displayed, is it important and recommended to fill up gas again, with one cell remaining or two etc.

Those that do their own maintenance, how do you get rid of that Oil Maintence Due Soon message that pops up when you start your Prius?

Is there anyway to disable this annoying "press brake pedal to start" on the 2010 with Vag Com or some other magic tricks? I searched and found a thread but no solution if there is any.
