    I hope someone has an idea for my mistake/problem.
    I left the dome light on when I went on vacation and the 12v battery died.
    When I returned from vacation today I unlocked the car with the manual key.
    I opened the hood, I opened the fuse box and found the 12v battery post. I connected the 12 volt jumper cables.
    When I connected the other end of the cables to the pickup truck that was giving me a boost… The Prius locked its doors! With the key and remote inside!
    The prius battery is charged now (somewhat) because any attempt to touch the door now sets off the beep beep and then the alarm.
    I don’t have a spare key. Any ideas about how to get into the Prius short of purchasing the key and remote to be made off the serial number? I suspect that route will be very expensive.
    Thanks,
    YiaYia

    Hi YY22G,

    Well, hook a resistor to the charging post and run the 12 V battery back down. Then get a cop to use a jimmy to open the door by fishing it down the between the window and rubber seal. Then recover the key, and recharge the 12 V battery. Or at least that is my guess. With the 12 V battery down, you should be able to open the doors with the mechanical jimmie, without the car reacting to relock them, and set off the alarm....

    Wow, that is impressive. I didn't think it was possible to accidentally lock the keyfob in the car, but I never thought about running the battery down first. :madgrin:

    Why can't you unlock the door again with the manual key?

    I think the mechanical key is inside with the keyfob now.

    Possible solution would be to disconnect the +12 V cable at the underhood fuse box, then use a slimjim to open one of the doors. Don't short that +12V cable on anything under the hood.

    The metal keytag that comes with your keys at purchase is the key cut code for the metal key.

    I read about this at another website, do you have this 'key cut code' . ( I purchased my prius used, and don't have it , yours is newer.) This would help the dealer make a new mechanical key, not sure if they can just make it with info from their records.

    I might also remove some engine fuses (recording which ones) so the car can't be easily stolen, until you find the solution to this.

    Oh of course...thank you. But the op's post made it sound otherwise.

    I got a hideakey magnet box for mine. Just a copy of the mechanical. I know...its stupid as I could not figure out a way that I would need it. But I had a magnet box from another car I sold.

    Just get someone to slimjim the door lock. It's easy enough to do.

    Does the Prius relock the doors again when in active alarm mode? My GF's Avalon does this. Every time you open the lock with the slimjim, the car relocks the door again. It sucked because the AAA tow truck guy tried many times and scarred up the door jambs before he finally gave up.

    I don't know the answer to this. It seems odd that it would, as you need to be able to manually unlock a car door, and a proper slimjim job is the same as pulling the unlock lever. However, that said, I have no idea if the 2010 does that. That would be the suggestion about pulling the power before using the slimjim.

    In the Avalon case, the car "knows" it is supposed to be locked and the alarm is armed, so each time you get the door mechanically unlocked, the car uses the door lock solenoid to lock it again.

    I've never tried it on the Prius; no reason to since even my GF has not been able to lock the keyfob in the car. :madgrin:

    The car does not lock itself when using the slimjim. Long story short, I had to call AAA and they opened up the car in about 10 seconds. I was a little disturbed that the alarm didn't sound. This is probably the cheapest way to get your keys. You can sign up for membership over the phone and they'll send someone out. Good luck
