Prius (2004-09) :: Can't Unlock The Doors With Smartkey
Dec 20, 2015
…well, I guess it just had to happen sooner or later! I was out running errands yesterday, and when I returned to my car, found that I was unable to unlock the doors, so I tried the buttons on the SmartKey FOB all to no avail, so ended up using the mechanical key to unlock the door, and placed the FOB in the slot in the dash. I checked the FOB battery when I got home, and found it to be slightly less than the 3.00V, plus the fact that it was quite cold yesterday, so that might have been a contributing factor. I've not needed to replace the FOB batteries in the 2 years I've owned the car.

Any way to program my Prius to unlock all the doors with one click of the FOB?

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 have a problem with my '08 driver's door lock. Essentially, the doors will all lock just fine using FOB, door buttons, etc, and all doors except driver's door will unlock using smart key features, fob, etc. However, if I want to unlock the driver's door I have to insert and turn the key. It feels a little stiff but it might not be any different than before as I rarely used this feature before. There was a period of about a week where it would fail intermittently before it began to fail consistently.
It just got warm out here in MD, not sure if that might have made a difference. I popped the rubber door plug out to lubricate it the lock mechanism with some silicone spray and also sprayed some in the lock itself, but it did not make a difference.
I am trying to avoid an expensive repair, but I am not really up for a complex replacement of the actuator motor - and it seems like the motor must be working anyway if I can lock the doors. I have not done anything in the latch area, just near where the key goes.

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.

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)

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.

I just got a 2005 Prius with only one key. The key has always worked to start the car, but never worked to open the doors or set off the alarm. However, when I press a button on the key to try and open a door, the little red light turns on. Do I just need to replace the smartkey battery? Or is there something more complicated I need to do, like reset something?

After going through a car wash my Prius has started locking all doors when I start the car and unlocking driver's and passenger front doors when I turn it off. Kind of wondering how this could happen, but since I like it that way I don't really want to change it back. Is there a way to toggle this and can I change it so that rear doors and hatchback unlock also when I turn the car off?

Possible to unlock ALL doors when using the smart key?

I can set the V to unlock all the doors when I unlock the driver or passenger door? I see that setting on the manual on page 524:
Smart Key System: Select doors to unlock: Driver's door or All doorsClick to expand...
But it looks like on the Display Audio system, it cannot be set. Can the dealer set it instead?

In the owners manual, there are instructions to set all doors to unlock instead of just the driver's door.
I followed these instructions. Now all doors unlock with the smart key (grabbing the drivers door handle), but NOT by pressing the unlock button on he fob.

My Key FOB is only locking the doors but won't unlock.

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?

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.

I have a 2004 GX470, fully loaded. When I shift into drive from park, all my doors automatically lock. However, when I park and shift back into park, the doors do not unlock...I have to manually press the unlock button. Is this how it is supposed to be? I have ridden in later Lexus's where the doors unlock when you shift to park. Or is there a switch or method to get the doors to unlock when shifting into park?

Prius sat in my garage for about a month without moving went to start it up had 0 power, the unlock button on the keys wouldn't even open the doors. So I tried to jump start the car which would kind of work. The car would turn on for a few secs maybe 5 sec then turn right back off. So had the battery tested and came back as bad battery.
