Prius (2004-09) :: Intermittent Non-SKS Remote Unlock When Leaving Car Locked Overnight
Feb 22, 2013
I've had this problem twice now, and concerned it might get worse. After leaving the car locked over night the remote unlock (pressing the unlock key on the remote) has no effect at all, on either my original nor virtually-new remote. Then a few minutes later everything is fine and stays fine for several months.
This morning I had to open the driver's door with the mechanical key, and the alarm of course went off, but stopped as soon as the car got to "READY", and is now fine again.
12V battery voltage looks fine (not great, but okay) and no other odd behaviour. (Oh, except the radio doesn't come on in high temps unless "tapped")
Normally the main remote will operate the locks from a hundred feet away. Even when it's not working the red light on the fob flashes as normal. I haven't checked the dashboard key light...

I have a 2001 passat that i have had for about 2 months. recently, about 2 weeks ago, i started having problems with the remote unlock feature. it will unlock the driver side door fine, but when i press the unlock button twice, the driver side lock makes a noise but the other three doors remain locked. when i press the unlock toggle on the driver side controls with the window controls, all the doors unlock fine. i have two remotes, one is pretty new and i just got it programmed (within a month) and neither one will unlock all the doors.all the other functions of the remote work fine.

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.

Last night, my son went to grab something out of the car so I dont know what he did but when my wife went to use the car, all the doors were locked. The headlights were on. The car was not running.
We were unable to unlock the doors with either remote. I believe it would beep 3 times but wouldn't unlock. I had to use the key built into the remote to get the doors unlocked.

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 traded my 2005 prius a year and a half ago for an '08 which apparently was a rental car for 40K miles before me. It came with only one key(not a SKS)which recently quit unlocking the doors and hatch remotely. I looked under the steering column and there is only a reset button for the tire sensor guage, and a couple blanks, presumably one would be for the remote/smart key reset.
I am currently using the enclosed key to manually unlock the doors. The remote works as usual when I place it in the slot to start the car. I live an hour plus from the closest dealers, and would love to address this issue without having to go there. I checked the FOB battery and even replaced it, although the voltage was practically identical between the existing battery and a new one. The little red light is operational when i press lock/unlock. The car stays outside - i don't have a garage, and remains unlocked between trips. Recently it sat for several days in the last large snowstorm. When I finally drove it up the 1/3 mile driveway, it would not lock when i was ready to leave it up on the 'hard road'. I've checked out a few related threads, but haven't hit on this issue yet. Perhaps the 12V battery is weak?

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.

Remote unlocks the other three doors but I need to jump in an open drivers door from inside.
Does not happen every time but has happened several times. I look like an idiot climbing in from the back seat.

I happened to read the following passage on page 37 of the owners manual discussing usage of the wireless remote control:
To Unlock: Push the unlock switch once to unlock the driver's door alone. Pushing the switch twice within 3 seconds unlocks all the doors simultaneously ... This double switch operation to unlock all the side doors and back door can be changed to a single switch operation. For details, contact your Toyota dealer.Click to expand...
(Note that this is different than the "smart unlocking" operations discussed on page 32.)
I'm interested in having all the doors unlock with just a single press of the remote unlock button. How to achieve this setting?

2004 Echo........
When I use my key to unlock the car door, I can turn the key and get all the dash lights but I don't hear a sound.
When I use the remote unlock, and try the same thing, my car starts. Is this a problem with the security system?

When I use the remote to lock/unlock the doors the drivers side door won't activate . . . .unless it's really cold outside. The other 3 doors work year round.
Sounds weird but as the weather gets colder the lock on the drivers door will start to work. As winter turns to summer here in Illinois it starts to act up again. When it does work, it seems that unlocking works more consistently than locking.
Asked the dealer to have a look at it. They said it was a "weak actuator motor" and suggested to replace it. Sounds bogus to me.
I've tried to have a look down there but I'm afraid to take it all apart for fear I won't be able to get it all back together. Are there adjustments that can be made to the linkage or are lubrication points that might get this thing back working again . . . . . . all year long?
I also noticed that manually working the passenger side lock will lock the rear doors but won't lock the drivers door so it's not the remote. I never paid attention to whether manually working the driver side lock would lock the other doors but I think not since the buttons are right there on the drivers door.

We keep our Prius in the garage. With our previous cars, my wife would leave the keys in the car overnight, If it was in the garage. I'm wondering with the smart key if having it in the car overnight, but not in the slot, would cause a problem.

I am new to the web site and new to owning a Prius. Recently my wife and I bought a 2013 Prius two. I have a couple questions about the settings menu on the display. When you hit the set up button and then 'vehicle' it gives you a list of several items you can turn on or off. The first few are pretty easy to understand such as the doors unlocking at a certain speed or when shifting to or from park. But the others I've tried to search for what they mean and can't find anything. So my questions are:
1. What does 'Remote 2-Press Unlock' mean? And
2. What does 'Key System with Elec. Key' mean?

In comparing the battery drains on a Camry hybrid versus a Prius Gen II hybrid I discovered both have three stages of battery drains after a door open incident. On a Gen II Right after the door is open the drain was 1.37 amps.

My hybrid battery has been running low the past few days. This has never happened before, but it has been around 90 degrees out during the same few days. I noticed it this morning as I left for work. It was down to two bars when pulling out of the garage. I was getting pretty nervous, but at least the ICE was charging it. Although, it never fully charged the system, as I live pretty close to work. On the way home, I tried to drive around for a mile or so to see if I could get the battery fully charged.. The best I could do was four bars. Is this typical of the hybrid system in warm weather? Should I be worried about it? Also, the system has a fan, why doesn't it come on if the hybrid battery is so temp sensitive?

I own a 2009 touring that I bought with 96000 miles and now have about 105k on it. I have changed the 12v battery to the optima and changed plugs, transaxle fluid, inverter fluid about 4 months ago. I have changed oil and filter twice since I owned it. (June 2012)
Now the problem, I got stuck on the Long Island Expressway (aka the LIE "the worlds biggest lie"), the snow got too deep and I was struggling to keep going. While driving the slip warning light (VSC)came on often.
I had a friend with 4WD tow me home about 10 miles varying speeds from 10mph to about 35mph, I kept the car in neutral most of the time and when I saw hybrid battery getting low (last blue or first purple)I would put car in drive to charge it. When we got to my house, I had to dig out a spot in front then was able to drive vehicle for the few feet to get it out of the middle of the street.
Yesterday I tried to start car and it looks like the 12v battery was drained. I am. It sure if I pushed the park button and then turned car off but I do normally so I would say that I did. I tried to jump it and I got lights on dash with the dreaded red triangle and engine light among others. The touch screen display read that the vehicle was not in park and I should get to a flat surface and apply parking brake. Also the light on the power button would sometimes be green and then go amber and the park light was flashing green. I could not get shift lever Togo into drive or reverse or neutral.
I did put a trickle charger on it overnight from the engine compartment but have not ventured out there yet.

Will it drain the battery to leave the rear hatch open for extended time? i.e. for tailgating or camping (2008 Prius)

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.
