How does the Smart Entry / Smart Start system work?

Smart Entry and Smart Start allow you to unlock the doors and start the car without having to take the key fob out of your pocket.  Prius senses the fob in your pocket; just touch the inner surface of either front door handle (or press lightly on the rear hatch handle) to open a locked door, and just push the Power button on the dashboard to start the car.

If you have the SmartEntry Fob in your pocket and you walk away from the car while it is running, the car will beep at you a few times, and a yellow warning icon on the dash lights up: a picture of a key with an exclamation point over it. But the car keeps running.  If the person with the fob stays away from the car, someone else can still get in and drive it since it is still running, but the warning light remains on (so remember to Power Off the car before leaving it).

While the car is running (in park) it will not let you lock the car doors by pressing the electric door lock button by the arm rest while the driver's door is open. It is also not possible to lock the car from the outside by pressing the button on the door handle if you don't have the fob on you. So if you leave the car running, it won't let you lock the driver's door and lock yourself out of a running car if you don't have the fob with you.


What happens when the battery in the fob dies?  Can you start the car?

If the fob battery dies, you can still start the car with the fob.  The slot you put the fob in will sense the chip in the fob, even if the fob battery is dead.  Your remote entry buttons on the fob won't work, nor will Smart Entry / Smart Start if you have it.  But the mechanical key will get you in the car and the fob will start it.


 

I left the fob in the dashboard slot overnight, and now Smart Entry / Smart Start doesn’t work.

Smart Entry/ Smart Start was disabled because the fob was left in the car (for more than 10 minutes after Power Off). There is a button to the left and under the steering wheel labeled 'SMART' which controls whether the Smart Entry / Smart Start system is enabled or not. Push it twice to re-activate Smart Entry/ Smart Start.


 

Is there any way I can program a new fob myself?

No. Unlike the Classic Prius, the 2004 requires a Toyota Handheld Tester (THHT) to program the fobs. To date, no manual method has been found.

Not only does it require a THHT, but the Smart Entry/ Smart Start fob requires three separate programmings to work, and the non-Smart Entry/ Smart Start fob requires two separate programmings. These are:

And if they want to test the battery in the remote, they need: Note the sections above were from the Preliminary Manual, the same as online on TIS last fall, but the section #s in the printed manuals are completely different in some cases (one section was near impossible to find in the printed manuals, it was about 200 pages away in a different section).
