How do you lock a Prius door?

To lock the doors, make sure they're all closed, then touch the two grooves on top of the front door handle. You should hear a single beep. If they don't lock and you hear a steady warning tone, one of the other doors is probably still ajar or you left the Smart Key in the car.

Can you lock a Prius without the key?

6 Answers. No, it will not stop mid-ride. It will warn you the key is no longer in the car, but as long as you don't turn it off, it will keep running until you run out of gas or the car battery dies. It would be a safety hazard for it to randomly die, or even a slow turn off.
