Default FOB Problems

My Aunt has a Toyota Prius, I believe it is a 2004, Maybe a 2003. It is the newer body style and i'm sure it isn't a 2005.
I was cleaning the inside for her last night and this morning the fob does not start the car.

I have several hypothesis, none which i can test because I am not there anymore and have no access to the vehicle.
1. There was some button under the steering wheel with a key or something on it that i may have accidentally pressed.
2. I put the fob in the little slot to see what would happen, i then decided whatever and took it out.

Any Ideas? I tried to search and apologize if there in an answer here already. It isn't my car and i can't be there to try things.

You are probably right. You probably turned off the SKS system by pushing the button on the lower panel under the steering column. She should just be able to push the button again to reactivate it.

so, i called my aunt and uncle and they tried with the system with the button on and off. They can't get the fob to do anything. They had to enter the car with the mechanical key.

Is there a battery in the fob which could be empty and needing to be replaced?

They need to leave tomorrow morning for a trip so i'm trying hard to figure this out.

It might. It seems like a bit of a conicidence with you washing the car, but if even the push button locking and unlocking isn't working, it certainly could be the battery. Don't they have a 2nd fob? That would answer that question.

There is one other possibility. Does the car start when you put the fob in the slot and do the interior lights work? It's possible you left a light on when you were washing the car and killed the 12V battery. If this is the case, follow the instructions for jump starting the car.

Good luck.

to clarify there was not a lot of liquid involved with this washing... mainly vacuuming some stain remover on carpets, and cleaning wipes on the dash.

but thank you, i am pretty sure that if it is not the battery on the fob that it will be the battery on the car.

I'm betting it's the car battery. It happens to a lot of people. The fob keys don't tend to immediately go. They tend to lose range before they completely go so you have some idea that it's coming.

You don't need SKS enabled to use the remote lock function on the fob. If that doesn't work then either the fob battery is dead, or the car battery is dead.
There is a little LED on the fob that lights when you push a button on the fob, or if the car sends a signal to the fob that the fob then responds to. If this light lights up, the fob is probably OK.

As mentioned, you can try the personal lights in the car. If they don't come on, then the battery in the car is probably dead. If they do light, it still doesn't mean though that the battery has enough power to do other stuff. But then, if it has enough power to light the personal light, it should have enough power to respond to the fob and unlock the door. Although, when the door locks and unlocks electronically, the parking lights blink, which consume quite a bit of power cumulatively.

If the car won't power up with the fob in the slot, it is likely the battery in the car. The fob's battery is not necessary when the fob is in the slot; it will work in the slot even when the fob battery is dead.
