Change door lock setting to open all doors

Stand outside next to your car and hit the lock and unlock buttons on your fob. Hold for 5 seconds (or until your car talks to you).

 

I think it's actually pressing the lock and alarm buttons together for a few seconds, until your car beeps.

Try both, one method works for sure

 

Yes. Instructions to do that are in the owner's manual. That method worked for me (unlike their instructions to stop the infernal automatic locking and unlocking when shifting into or out of PARK).

 

Wait a second.
I need clarification as to what is happening here.
You're saying when you walk up to your completely locked Prius, when you get near the vehicle your drivers door automatically unlocks....before you even touch it?
Because as far as I know, if that's the case, it shouldn't be doing that, and isn't designed to do that. It should only be unlocking when you approach, and actually touch the door handle/sensor with your hand. You'll hear a beep and it will nearly simultaneously, instantly unlock and open.
You can program the vehicle to either ONLY unlock the drivers door, OR also unlock all the doors upon TOUCH of the handle, but it shouldn't be a situation where the drivers door is unlocking without you touching it, and then facilitating another touch to unlock the passenger side.

 

I strongly agree with the last statement

 

It's a security feature.

My FORD works like yours does - because I changed it to do so (though I have to press the unlock button - old technology). Where I used to work was a relatively unsavoury location, and for security reasons I elected for it to only unlock the driver's door so nobody else can jump into one of the other doors as I unlock it - an unlikely situation, but I was in a highly sensitive workplace, so anything was possible. I have to double press the unlock button to unlock all doors on the unlikely occasion when I have a passenger.

 

What he said! ......

 

People are assuming it unlocks BEFORE you touch the door handle? Are you saying that's the case? I suspect you're not, but if you are, how do you know? It unlocks when you touch the door handle and that can be set to open all doors, mine is.

 

Its REAL simple if it's simply a case of wanting to program the unlock to be for all doors.
Even though I did mine so long ago I've forgotten how.
It's can be done, and it's not very hard.

 

Easy. Foot OFF brake, press power button to turn car on Accessory mode. On key, hold lock and unlock for 5 seconds. Based on your model, you have two or more modea, as far as which door handles will unlock and which doors will be unlocked. It's in the manual, either On the 40s or the 60s pages if I remember right.
