    My 2015 Prius is locked. Neither the FOB or emergency key work?

    Well the emergency key has to work right? If it's the right key for the car, you'll just need to turn it with a little more force. Maybe try a pair of pliers to turn it. The keyfob might have a bad battery, so if you have a spare keyfob, you should try that

    You wrote the physical key does not work? Do you mean it does not turn?
    Either direction? There may be moisture in the lock, and it's been cold, it
    might have frozen, I know it's not that cold, but maybe enough.

    Does it go into the lock? You could try spraying WD-40 in the lock, it might
    free it up, if that is the problem you're having.

    And you're physically in Ocala Florida with the car wasn't it like 80° yesterday You've had the car since it was new You verified that the metal key actually worked at one point or it's never been out of the fob as long as you've had the car? Most people I know have never had the physical metal key out of the fob most people I know so they wouldn't know if they've been sold the car that the metal key doesn't even fit. I've seen a few locally they've had the transponder programmed and all that nonsense works but the physical metal key doesn't belong to the car It got lost or they forgot it was there whatever happened so there's always that so the next thing to do is to get the window away from the gasket a little bit reach down there with them pretty stout unlocking tool and usually I can flick the door leave her out so that I can just pull on the handle and open the door people that know how to use the tools can make this happen. But it sounds like you may have a programmed fob that works correctly but the metal key goes to another vehicle not yours this is possible.

    If your fob doesn't work, your physical key doesn't work, then you are in the same boat as everyone else who left their keys in their car.

    Actually, I would also try replacing your keyfob batteries. Or try the alternate key.

    If everything fails, you call your roadside assistance. They will send someone to shimmy the car door to unlock the car. You will be amazed at how fast a car thief can get into your car.

    My teacher once left his car keys in his van. I watched a guy shimmy his way in with a thin tool that fits between the window/door frame within a few minutes.

    Couple of thoughts:

    when using the physical key, clockwise unlocks, and vice versa.

    replace the fob battery?

    The physical key is mechanical and has to be cut with a wavy groove over the uncut straight groove as shown here.

    Otherwise the lock mechanism could have a connecting piece broken or disconnected.

    I would certainly verify the fob battery but your car’s battery could be dead as well.

    Do you see the flashing “immobilizer set” indicator on the instrument panel? From the outside it may look like a simple flashing red light.

    It should flash 24x7 when the car is off. No light may mean the car’s 12v is discharged which would keep the fob from working.

    Extra points if you still have the key code that allows a new key to be easily made by any locksmith.

    The metal plate came with the original fob but the 5 digit code is all that is needed.

    I suspect thieves may have hacked your sks system and changed the manual lock cylinder.
    Considering having it towed to a safe place immediately

    I had a AAA response and they were able to unlock the door. You are right as I did not turn it with more force.

    The AAA responder was able to work the key and open the door.

    I bought the car used. The AAA responder was able to turn the key and open the door.

    Just curious: Then why didn't they take the car? Are they waiting for better weather or something?

    He Stated that AAA was able to open the car with the physical key. Does that work on Gen 3's when the battery is dead?

    Yes, the physical key requires no electricity

    You’ll have to ask them, who can figure out the mind of a criminal?

    The 12v battery was dead. Jumped and off to the races.
