Prius (2004-09) :: When Outside Temps Go Below 20 Car Won't Lock / Unlock
Jan 3, 2012
Second time I've had this problem this winter. 2007 Prius, about 65K miles. When the outside temps go below 20 or so the car locks seem to not want to work. For example this morning temp was about 19, smartkey unlocked the car ok-took a couple of button pushes but it worked. Car started fine. Drove to work and after shut down couldn't lock the car. Smartkey didn't work, pushing the door button didn't work. Lock switch inside the car works, so I locked the doors except driver's then used the manual key to lock the driver's door.
I've checked the battery using the internal maintenance screens, no load voltage about 12.3V, Load voltage 11.7Volts, Charging voltage 14.3 volts. I know I'm due for a 12V battery with it being 5 years old and such, and I'm pretty sure a good cold day will kill it dead. But, other than the battery...

I am experiencing with my key fobs on my current 2004 Prius. The issue is that I am unable to unlock and lock the car via the SKS Remote, and I am only able to turn on the car via inputting one of the fobs into the slot to turn on the car.

My daughter picked up an 08 Base, option package #1 yesterday. It has 166K miles and checked out okay by me (coolant moving by inverter pump, no signs of water in spare tire well...etc.). The car only had 1 key fob (non-SKS) wit no spare key or fob. The key is uncut but the remote starts and runs the car. The remote will not lock or unlock the doors.
The first thing I did was replace the CR2032 battery with no change. It still operated the car but not the locks. I noticed that the little red light wasn't coming on when pushing the buttons and found the red panic button was stuck. Took care of that and thought all was good until I tried to lock and unlock the doors again. Nope! Light comes on, works in slot to start the car, but not the locks.

I bought a used 05 prius about 3,4 years ago. It came with only one key, but everything was fine, except for few minor things. I have changed 12v battery within a month of purchasing this car, to optima yellow top as many priuschat users suggested.
I bought another black logo fob (non-SKS) on ebay, and get a spare key, but no luck. I was trying to do as fast as I can, but the anti theft light never came and stayed on (entering programming mode).
All of sudden, I noticed the fob doesn't lock/unlock the vehicle, but still starts the car. Since then, i unlock with metal key, then start with key fob. Manual door lock/unlock button works fine at driver side. However, when i try to lock the door from passenger side manually, it unlocks the door right away.
Thinking about getting a mini vci cable with techstream to setup a key fob after checking the 12v battery. but it only have been 3,4 years, seems it is too early to replace 12v battery.

I have to use the mechanical key on the SKS to open the door, then plug into the slot on dashboard to start the 2004. Replaced battery, nothing changed.
There are two causes I suspect:
1. The CR2023 Battery was bought on Amazon for cheap, about 6 month ago. What's the voltage should be if no load?
2. The plastic cover on the SKS was broken. It could be that rain or not-so-clean-water gets into the electronic part.

I just bought a used 2005 from a small dealership just today.. It does not have SKS (no black buttons on the door handles).. But, the dealer said it had a key problem, so he discounted the price.. He said that the keyfobs can start the car, but can't lock/unlock the doors.. He gave me 2 keyfobs, but I'm not even sure if either of them are the original ones that came with the car.. I think they might both be used keyfobs from other cars..
In other words, I don't have a master keyfob that can unlock the doors yet.. I always have to take out that darn physical key to unlock it every time..
I've looked around lots of threads already, and all it does is confuse me..
I know you can do some weird "chicken dance", but it seems like you already have to have a master keyfob that can unlock the doors, right?.. And I know there are "2 sides" to the keyfob: a "prox" one, and some thing else (I forget)

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 just bought a new 2006 prius and have an issue with the FOB (it's pretty beat up from use -- ordered a new housing for it)...
It works great for locking and unlocking the car with the key in pocket, but as soon as I sit down to turn on the car, I get the beep and key icon flashing on the dash and no activity.
Only when I insert the key into the slot will the car turn on. The Key disable button under the steering wheel is not engaged.
Again, it recognizes for locking button and unlocking when I touch the handle, but I have to physically plug it in for the car to start....

Prius owner, Just bought it 3 days ago! 2007 no nav system, but the key fob is the silver logo and has the key button on the lower dash...so I assume it is a smart key system. However, the key fob will not unlock or lock the car, the panic button doesn't work either. The car will only start with the fob in the slot.
Why will it start the car only in the slot? I changed the battery out in the fob and it still didn't lock/unlock. I didn't try the smart key start with the new battery...I don't even know if I have a smart start. Why does it not open/lock the car?

The dear wife crashed our 2004 Prius, crumpling the entire bumper and left front side. The body shop has fixed everything nicely, with one small exception. There is no longer the reassuring beep(s) when using the fob to remotely lock or unlock the doors. The lights flash, as before, and the panic alarm still works.

Wife just called with a weird one. She said the doors won't lock - using either the key fob or using the door lock/unlock button on the car interior. They will lock, and then immediately unlock. Won't stay locked.
Since the car isn't here, I'm shooting in the dark, but I'm having her check:
Make sure all doors are properly closed/latched. Push a button on the key fob to see if the LED lights up (I changed batteries a year ago).
Couple of searches showed up:
Potential issue with lights on when car is turned off (never had this issue before). Someone mentioned a switch below the dash to right of steering column.

2007 Prius here. A few months ago I had a similar problem. Basically when putting my hand on the door sensor, the doors would cycle through unlocking (noise, lights flash etc) without actually unlocking. If I keep pulling the handle after each attempt it seems to go forever.
The front passenger door also did not lock under any circumstance.
Took it into Toyota, they absolutely screwed me I now realize, $900 to replace a door actuator in that passenger door.
Worked fine for a few weeks. Then all of a sudden, problem started again. Just like last time, slowly slowly over the course of 2 months, it got worse and worse until today I could not open the driver side front or rear door at all.

I've looked around here and in my manual but can't find the procedure to turn off the "beeps" when I lock and unlock my car via the key.

Recently, I've been having issues with my door locks. When exiting the car, and pressing the door lock on the outside handle, I would here the door lock solenoid fire once, then open, and the door would not lock. Same thing would happen when I used the FOB. The door would not lock. On occasion, I would get the door to lock, and stay locked by using the door lock inside the car when the door was open.
On the occasions when I did get the door locked, I then had issues unlocking. If I approached the drivers door to unlock the door, the car would just keep repeatedly beeping, and would not unlock the drivers door. But, the back door would unlock, so I could reach in, and open the drivers door from the back.

I have a 2010 Prius with about 51,000 miles on it. About a month ago the front passenger lock actuator began failing and wouldn't lock/unlock with the remote. I had to manually slide the lock shut before I exited the car or it would keep beeping when I pressed the lock button on the remote.
Well, now the driver's side door is doing the same thing. When I touch the front door handle (to unlock the doors) it beeps like 8 times while it tries to unlock all four doors. I have to open the back drivers-side door and manually unlock the front door so I can drive the car.

My passenger rear lock is no longer lock/unlocking via power. I had an issue with the driver front, but it was replaced under warranty. Since it's a 2007, it's certainly no longer under warranty.

My FOB doesn't work locking/unlocking my '06 prius. I use the embedded key to lock. When I want to lock it, I lock it from the inside.
a. I know the door lock actuator motors are not bad because I was able to lock it from the inside using the lock/unlock switch on the driver side door panel.
b. I checked the voltage on the AUX battery. It read 12.4v. So that is not the problem.
c. Key fob battery strength is good (I see the red LED every time I use the remote).
d. I don't have a SKS system so no switch exists to enable or disable the SKS under the steering.

While on a recent vacation, my sister-in-law, trying to do a good thing, washed my clothes but neglected to remove my FOB for my 2008 Prius. I returned home only to find that the FOB would not lock/unlock the doors.
I replaced the battery (the old one was reading only .03vDC) but still no remote lock/unlock.
How can you tell if the FOB is working since there is no "little red light" like I have seen mentioned by other owners
It looks as if the FOB should be watertight, is it? Any way to clean inside the FOB in case there is some corrosion? What should be my next step?

When I lock or unlock my Prius C with the handle or the key, it used to beep, now it no longer will beep, I've checked the doors and hood to make sure they are all shut and it will still not beep.

All other doors lock and unlock except drivers door. The drivers door can only be locked unlocked manually with your hand.
