Prius (2010-12) :: Smart Key Stopped Opening The Door / Car Not Starting
Jan 18, 2013
Recently bought a 2010 Toyota Prius 1.8 and it was working very well. It used to display a message saying that the key battery is low. Then one day, the smart key stopped opening the door. After some reading on the forums, decided that the smart key battery might be really low, so used the mechanical key to get in and tried to start the car by placing the Toyota logo of the smart key on the power button. Since nothing happened, decided to replace the batteries anyways. After the replacement, tried again, but zip. The doors still won't unlock, and the proximity switch-on also is not working. Why? Is it an issue with the 12-v battery?

Kind of annoying open your door, then hit the unlock button. Is there an option or some hand motion to unlock both doors when you grab the handle?

We've had our '11 Prius II now for a couple weeks, and I have run into a problem I can't seem to figure out. When I lock the car, either using the button on the FOB or the smart key, then come back and try to unlock it using the smart key, it will lock the vehicle again. I have to wait a few seconds and try the smart key again and then it will unlock. I tried the search, but haven't found any thing describing this. Am I doing something wrong?

2013 Prius 4 ... A deer was trying to hitch hike but didn't give me warning before lunging into the passenger door. I found a salvage door that will work. I have switched all the wiring, speaker, locking mechanism and mirror but I need removing the door handle(outside). I suppose the sensor that matches my key fab needs to be transferred to the new door but I can't see how this is done. Looking for the instructions on removing the door handle?

One morning last week I opened the car door and it started to beep real loud - like an alarm set off (I don't have an alarm system in my car) - It lasted 30 seconds. I went about driving the car and it ran fine. I stopped at a place - went out and came back to drive out again. As soon as I opened the door the alarm went off again. This time it lasted 20 seconds. I have not had the issue since then -(a week gone). What could be wrong. I know it happened and will happen again. I don't know if battery is low - everything works fine and car is running like a charm. battery indicator shows full when on the road. I can't recreate the problem.

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've had my 2014 Prius II for about a month now and am really happy with the car. I do however have a question. Every time I go the garage and open the driver's door to get in the car, I hear a servo-like noise under the hood lasting for a few seconds. probably 5-6.

We have been tolerating a bad squeak in the driver's side front door upon opening, closing (any type of swinging of the door). Dealer tried lubricating it with no success. They told us that they would order a new hinge and "hope" that resolves it. I am a little worried about this. Would you trust your dealer to remove and re-install the door or just live with the squeak?

I was having battery issues and had a friend hook up a battery charger to my car today. They pulled some relays to see if they could figure out why it was starting right. When I left for work the car started fine but I notice my windows would not roll down at all. I figured no biggie I would deal with it tomorrow.
When I got to work I realized my key fob had stopped working too. Again, I have a key will unlock it after work and deal with it later. After work tonight, I go to the car, I tried the key fob and nothing. No surprise. But I unlocked the driver door and it won't open, try to unlock the trunk it won't open.
I was told they pulled the relays and reseated them when messing with the battery. I can see a red light flashing below the radio. To top it off the keys to my other car are locked in the trunk along with my purse!

My wife and I recently purchased an 02 Camry. Last night the drivers door stopped opening from the inside and outside. Then we noticed the window was getting stuck rolling down and when I pushed down a bit the door popped open! Happened a couple times before the window got stuck.

A purchased a new 12 volt battery at the dealer. I was getting weird warning lights, so I had them run diagnostics. They said all the codes were voltage and I needed a new battery. Shortly after this I noticed the Smart Key no longer opened and closed the doors.
The car starts ok.
My question is this, could the changing of the battery have caused this? I tried searching for the answer BUT all answers refereed to adding a new smart key purchased on Ebay.

What does "Three-door Smart Key system" mean exactly? I have a proxy key on my car now but what does 3-door mean? Also, is the remote that is included that hideous, huge remote that looks generic and impractical? If so, are there aftermarket ones?

I've been having an issue with my smart key system since I did sound deadening on my car last weekend and had disconnected the auxiliary battery a few times during the process. I cannot get the driver door to unlock by grabbing the handle.

The noise seems routine. It happens when you get close to the car and open your door. I guess the car is anticipating that you will start the car soon and under the hood, some subtle mechanical noises occur. Just wondering what that noise is?

1) This is not battery problem, because smart function is work. If battery dead , smart function complete dead, and I change 2 new battery.
2) sometime smart fob can remote lock door. but 99% is not work. I don't know why.

I have a Prius 2007 with smart key, the problem is the driver's door does not unlock while touching the handle sensor pad. I works perfectly with the other door and with the hatch one. The interior light turns on when I get close to the driver's door which means that it's not the proximity sensor.
It stopped working like a year ago, the weird thing that last winter and during the snow time exactly it worked like there is no problem at all! After that when the weather got better it stopped working again! Is it something related to temperature/humidity? or it was just like a one off happened by chance at that time?
Is there a way to diagnose the touch pad sensor and fixing it?

I have a 2013 Gen 3 Prius II. 55k miles. Purchased brand new 2.5 years ago so I am out of warranty by mileage unfortunately.
One by one over the past two months three of my door locks have stopped functioning. Front left, front right, and back right. Sometimes if it isn't too hot outside my driver's door will work. Otherwise the car just beeps repeatedly when I walk up to it until I unlock it with my key manually. I've seen in some older threads that people have had the same issue. It seems to be the door lock actuators based on those threads. It's incredibly frustrating that a 2.5 year old car is having this problem on three doors. It also seems obvious that these actuators are garbage if 3 out of 4 of them have crapped out independently right around the same time.
Seems to be a very expensive repair when done by Toyota per door. I will have it looked at this week but don't have high hopes. Seems like you should be able to make a good case that the failure rate is too high if multiple doors are failing.

I have a Toyota Prius 2008 and my key fob has stopped opening and closing the doors. It's one where I can open and close the door using the buttons on the key fob but does not open or start the car from a distance.
Anyway, it stopped working. My wife's works fine. I tried changing the battery and tested both batteries on a battery tester and that showed full charge on both. When I place the battery into the fob, the red light on the remote flashes for some time then stops. It doesn't flash when I press any of the three keys. And the car will start and run fine with the fob.

I have read somewhere on here that you can reprogram your car so that when you touch the driver door handle to unlock, it unlocks all the doors. Can't find the thread now & can't find it in the manual. Looking for instructions how to do this or page number of the manual?

I don't drive a lot so on my 2008 Prius I could turn the smart key on/off with a button below the steering column and it keeps the system from constantly searching for the signal. That stop some of the drain on the 12 volt battery. My new 2013 Prius 3 doesn't have that button. Is there a way to turn the smart key system on/off easily?

I have a prius II, so you can only smart key unlock from the drivers door. Is there a way to get all the doors to unlock when you pull the handle instead of just the drivers door unlock. I frequently travel with a passenger and it would be nice to not have to unlock my door first, and then bend over and click the unlock button inside.
