    My 2006 Prius hybrid battery died a few months ago. It's been sitting idle for a while and now the doors won't unlock either with electronic or mechanical key.I've tried suggestions from this forum, e.g. pushing the key harder, squirting WD 40 into the lock, but to no avail. I've run out of ideas. Can anyone suggest a solution?

    Yes. You now also have a DEAD 12 V battery.

    The mechanical key unlocks the door independently of the 12 volt battery.

    Did your mechanical key ever operate in the door ever tried it to make sure etc sometimes people hand you a fob they danced in and got to work but the key has nothing to do with the car just saying. If it did get you some WD-40 in there first to try and clean and carry away whatever corrosion is holding your door lock tight which which really shouldn't be unless you're in an extreme rust area and even then this is kind of not the norm at all.

    I thought that was true.

    But not having the 4 actuators make a noise when the key is turned
    might lead one to believe that it is not working.

    Didn't the older models have a mechanical lock mechanism on BOTH
    front doors ?
    if so, do they both fail in the same manner ??

    Somebody here should have experience with doing that.
    I don't.
    Maybe a tow company would do it for you.......for a price.

    Not on the Gen 2. Only one mechanical lock on the driver's door.
    Your only hope is to use the mechanical key in the key fob. It would help to know if it has ever worked in the past. Whether the 12 V battery is flat or not is moot at this point as the key mechanism is purely mechanical and does not rely on the 12 V battery.

    If you've never used the mechanical key in the past, as stated earlier in the thread, it is possible that someone previous to your ownership changed the fob and left you with a key cut for a different car. If that's the case, you'll need to get a service like AAA to slim Jim the car.

    did you try a pair of pliers on the key for leverage?

    A possible play, but carefully. No telling if your local locksmith charges extra for getting into a car with the mechanical key broken off in there.

    I have read a lot of posts on this subject, but I'm still stuck. Years ago, when I first got "Sipper," she had a mysteriously erratic battery that I changed. I had to replace it again a few years later. (My low mileage driving and winter is hard on them.) I'm familiar with the fob being useless because of a dead 12V and have dealt with it. But, this time? No luck.
    This Winter, I was in hospital for a couple months after an accident. So the poor car sat and I have been preparing to go through the drill.
    While recovering, I knew I'd need a battery so I phoned the big-name auto parts store where I've bought 2. But they don't have a record of my purchases. (??) And I do not want their other far more expensive option.
    So, I decided to get into the car, get my receipt, I could phone and tell the store what to order for me, and have a friend pick it up. Then, I could get a jump start, open the hatch, and do the replacement.
    Today, on the way outside, I checked the fob and confirmed that the red light blinks.
    The 12V will be dead, so I wasn't surprised that the fob did not open the driver's door or make anything click.
    Pulled out the mechanical key which has worked before and which turned easily in the lock.
    Pulled the door handle which also moved easily. I pulled a bit more firmly. But the door would not open.
    Because I grease hinges and spray lube the locks every Fall, I expected them to move easily.
    But, it won't work -- and how did I get in before?
    Until I get into the car for my receipt, I cannot order the battery. I cannot release the hood to get a jump start which would then allow me to open the hatch when I do get a battery.
    But if I call a locksmith now, the car will have to sit open until a new battery arrives. We won't get more snow but we're due for the Spring Monsoons ... So that idea doesn't appeal.
    Having read through what others have said in various threads, and going through this latest problem, I have to admit that I am becoming less impressed with my precious Sipper . Why didn't Toyota leave a hatch release I could access from beneath? Or somewhere else? What about letting me get under the hood?
    I've done this before. What's my problem? I feel like I'm still on hospital drugs, lol. If I don't get this figured out soon, I'll be wishing I was.
    I guess the first question is this: The fob is not a Smart one but its battery is good; the mechanical key did work before; lock and door handle move freely. Is there anything else that could be wrong there ?
    p.s. Anyone looking to adopt a 2007 ?

    So right now today in British Columbia if you walk out to your car and insert the mechanical key into the lock on the driver's door the key turns If you look down while you're turning the key do you see or your partner from the other side passenger side of the car looking through the glass do you see the red dot on the lock button move back and forth does anything happen That's what we care about here that should be without a doubt happening It's physical now You're not doing anything electrical per se I would hope so when the door is unlocked and you see the red showing on the driver's door you can see it from looking through the passenger window or possibly looking through the windshield when the door is unlocked the red square is visible to the human eye That's unlocked once the door is unlocked and you pull on the handle why isn't the door opening My passenger door was stuck from a Coca-Cola that blew up in the car The sugar got on the door seal and it was worse than ice I could have broken the door handle I had to use a plastic splooge to wedge in between the door like a pry bar hold the handle out like I'm going to pull hard to open the car and use the plastic spluge to actually pry the car door open you could hear the gasket ripping It was actually not ripping it was the sugar that was glued to the metal paint of the door frame ripping right off the metal it didn't hurt the gasket once it was open I washed the gasket sprayed it down let it dry put some food grade silicone around the door seal which is what I normally do once a year and that's that so now you're to the point where you can see this red dot the door is definitely unlocked but you can't pull on the handle and the door won't open has anybody ever worked on the door before has the door panel been off? Any of these kind of antics going on change the speakers in the doors got nicer door panels from another car and installed them any of that because basically if your door is unlocked and your handle is pulled out on the outside try taking a screwdriver a plastic splooge and see what happens if you gently try to pry the door open maybe put a piece of cloth on the paint where you're inserting the screwdriver or the pry bar and be gentle we're not trying to kill the thing we're just trying to see what is holding our door closed sugar food material ice which I don't know what the weather is in BC right now so something is keeping your door closed like glue of course you didn't glue the door closed I would hope but good luck.

    Sounds like to me like you may be unlocked You just can't pull the door open did you have some kind of surgery that's made you physically a lot weaker or something or is it still really cold in BC and it could be frozen?

    It depends on how handy you are. If you have a local junkyard you would buy a used window and have the glass on hand then smash yours and replace it.(You can swing a spark plug on a short piece of rope and move it slowly closer to the window) I've done this for a friend and we had the spare junkyard window ON HAND before we even started. Very Messy and requires a lot of DIY. Took me about 3 hours. Or the inflatable airbags that AAA has can open the door a bit and use a slim jim to get it. Call around and get quotes from locksmiths.Best of luck to you.

    First BE SURE the physical lock linkage is working as Tom above suggests. Often the linkage breaks leaving you in need of a locksmith. Call one. It’s as simple as that. Once you have it open charge the battery or replace it.

    Sometimes stuff happens and you have to pay the piper.
