I have a 2012 Prius C III with key FOB and blue Power button. From the outside, the key fob allows me to open the front driver's side door (and the passenger side door) simply by touching a sensor by on the door handle. What I'd like to is how this functions we I am INSIDE the vehicle. For example, If I am parked and sitting inside the vehicle with the doors locked, will a person on the outside be able to unlock the door using the door handle sensor? In other words, can the door ever be truly locked wgilw I'm inside the vehicle with the key fob on my person? Thank you!
I don't own a Toyota like the Prius, but in my Nissan Leaf the key fob has to be outside the car within a close distance in order for the door button to lock or unlock the door(s). Actually the manual says that you shouldn't hold the key fob against the car while trying to lock or unlock the doors because the car could mistake the key fob being inside the car and won't allow you to lock or unlock the doors.
That's interesting. I've never thought about this dynamic. Theoretically the car knows you're inside as it won't let you lock the car "from the outside". But I don't know if you can unlock it. I'd bet it will be one of two things. Most likely answer: no. Possible second answer: only the front door that you're closest to... if you're in a front seat. I suspect that the answer is no, however.
The car will not let you or anyone else lock or unlock the car from the outside using the usual door handle touches while the key is inside. At least my 2012 C 3 acts that way. Also, while in the car with it off, you can lock it with the fob or the armrest controls. While in the car with it running, in any of its 3 "on" modes, the fob is deactivated (even the panic button), and the only way to lock the car is with the armrest controls.
