SKS

Press which black button? The one on your fob or the one on the door handle? 'Cause if it's the one on your door handle, that's your problem. The one on the door handle only locks the door. To unlock it (if you have SKS), you just put your hand in the handle, wait a sec, and pull (sometimes if you don't wait that split second, it won't detect the fob and unlock, but then it just takes an extra pull). Your fobs won't cancel each other out. Though if one person is in the car with the fob, and the second person tries to use SKS to unlock the other door, it won't work.

 

Heliotropehead: Yes, I am afraid you are doing something wrong! Several people have tried to open my car the same way so you are not alone. It does seem, from older model cars, that you would put your hand inside the handle, then push the button as a mechanical release. In fact the black button on the door handles and the rear hatch are for LOCKING the car! To unlock it, just touch inside the door handle. If you touch the inside of the handle, then press the black button with your thumb, you relock the car. I think there is a several second delay before you can unlock it again.

The rear hatch handle seems to to be a different material, requires an actual press and seems to delay about a second.

 

Don't worry, it's not an uncommon mistake. I remember when I first got my car, we were showing my boyfriend's mom the car how it "recognized" us when we got close. I noticed the little black square and said "I wonder what that does" and pressed it and voila--it locked the car! So I discovered it quite by accident.

 

As noted: the black buttons LOCK the car.

An additional note: you don't actually have to touch the interior of the handle to unlock the doors. Just the presence of your hand inside the space will unlock the doors.

I often do this to unlock the car and then open the rear door to put my dog in the back seat.

The hatch lock, however, requires actually squeezing the rubber handle.

This was explained on pages 28 and 29 of the 2004 Owner's Manual.

You may also be interested in reprogramming the behavior of the unlocking function. For example, I prefer to have all the doors unlock. Other options include having only the driver's door unlock when you activate the sensor there; all doors unlock if you activate the sensor on the passenger side or the rear hatch. Finally, you can have only the door whose sensor is activated unlock.

The instructions for programming one of these modes may be found on pages 30 and 31 of the owner's manual.

Finally, please read the note about Battery Power Saving (on page 32 of the 2004 manual.) If you are leaving your car undriven for several weeks, you should deactivate the "smart function".

Page 31 explains that it will be automatically deactivated if the key has not been detected by the car within 14 days or if the key is left within range of the car for more than 10 minues. In these cases you need to follow the instrucitons for reactivating the smart function.

I'm guessing the page numbers may be different in the 2005 manual. Unfortunately, at least in 2004, you will look in the index in vain for pointers to this subject.

Rather, go to the chapter on "Keys and Doors" referred to by the Table of Contents and browse through it.

 

Recently bought a 2009 EU Touring Prius. Only one fob came with the car, which has just two buttons (no red horn/panic button). Car has smart key system, as evidenced by the black square 'lock' buttons on both front doors and the rear hatch, plus the enable/disable button below the steering column.

Fob works, but smart key features do not. No door auto-unlocks and Start button requires insertion of fob into dash. Yes, enable/disable smart key button is in the enabled position. TechStream has no options for customizing smart key functions, but car is unlocking all doors with a single unlock press on the fob (not the default setting).

I am stumped for solutions. My only thought is that the 2-button fob is not smart key compatible. I have two 3-button 433MHz fobs (EU frequency, unlike 312MHz US version) en route and TechStream does have an option for adding new fobs to vehicle.

Does anyone have experience with a 2-button fob on smart key vehicle? Works or not?
