Smart key unlocks all doors except drivers side!

When you say 'driver's side,' do you mean the front and back door on the driver's side or just the driver's door? If two doors are not working, there might be a fuse or wiring issue.

If it's just the driver's door, try working the lock/unlock button on the driver's door arm rest. If the door doesn't lock and unlock with every press of the button, then you probably have a failing door lock actuator. Here's a great how to on fixing it: Fixed: Door Lock Actuator in Gen II Prius | PriusChat

Good luck.

 

x2 on the failing door actuator.

 

Did you look at the link provided in the second post in this thread on the door lock actuator?

SCH-I535

 

Before you bring your car into the dealer, read Fixed: Door Lock Actuator in Gen II Prius | PriusChat from beginning to end. The culprit is a tiny electric motor that can be purchased on ebay for a few dollars. They don't fail outright; they start to get weak and work some of the time (like when the sun is shining on that side of the car) and not others (like when it's cold or something needs grease).

The dealer will replace the whole lock assembly and charge hundreds for the part and labor. If you have the patience to do it yourself, it will cost four or five dollars -- a beautiful thing.

 

Did you figure it out? Mine is doing the same thing. Started two days ago and has happened twice so far. The car beeps a bunch of times like it's unlocking over and over again but never unlocks the drivers door.

 

maybe a bad motor, does the door switch on the armrest work?

 

Yup, once I'm in the car everything works. Makes me feel something is wrong with the remote maybe? Last night I couldn't use it to lock the car.

 

If it works from in the car, but only when it’s in ready mode, it’s probably bad door lock actuator combined with less than 100% 12V battery.

Does it work from inside of car in acc (power button once without brake)?
Or in ign-on (power button twise without brake)?
Or only on ready (power+brake)?

 

I just changed the battery in the keyfob hoping that does something. But when in the car with it on or off the door worked fine. When I would grab the handle from the outside expecting the door to unlock the car lights would flash and every other door in the car would unlock several times as well as the unlock beep would go off several times. It's very strange. I decided to change the battery as sometimes when I would hit the button the light wouldn't light up. Could this be some strange way of forcing me to change the battery before it was completely dead?

 

no, are you saying that changing the fob battery fixed it?

 

If I go back out to my car tonight when I get out of work and it doesn't give me an issue I'm going to call it fixed.

 

aye.

 

After replacing the battery I have had no issues. Very strange but effective way of telling someone to replace the battery.

 

OK this just happen to me and this is how I fixed it. With the car off hold down the unlock button the drivers side door arm rest near the window butons, keep holding down the unlock button while you turn the car on also roll down the window then roll the window up. Now turn the car off. Problem is now fixed. This is like a reset function.
