Hacker Helps Family Recover Minivan After Losing One-Of-A-Kind Car Key (bleepingcomputer.com)

An anonymous reader writes: A hacker and a mechanic have helped a family regain access to their hybrid car after they've lost their one-of-a-kind car key while on vacation. The car in question is a Toyota Estima minivan, which a Canadian family bought reused and imported from Japan. When they did so, they received only one key, which the father says he lost when he bent down to tie his son's shoelaces.

Because it was a hybrid and the on-board computer was synced to the battery recharge cycles, the car owner couldn't simply replace the car key without risking the car battery to overcharge and catch fire. After offering a reward, going viral on Facebook, in Canadian media, and attempting to find the lost keys using crows, the family finally accepted the help of a local hacker who stripped the car apart and reprogrammed the car immobilizer with new car keys. The whole ordeal cost the family two months of their lives and around $3,500.

    Using the VIN number, they can reproduce ANY key for ANY model the manufacturer carries. Sure it may be a bit of a hassle but with proof of ownership, any dealer can reproduce the keys. I've done it a number of time, a key just to get in the car is often free and a smart key can cost $150-250.

    For $3500 you could've flown to Japan, gone down to their HQ and flown back with a key.

      I read it and it's still bullshit stupid. The key doesn't encode recharge cycles. How would you have multiple keys? Regardless, having a failure mode that will intentionally overcharge the batteries is insane. The Japanese engineers are not that stupid. Advice from local mechanics about import hybrids -- yeah.

      Like any rational design the immobilizer is likely not part of the ecm but self contained or part of the bcm. Order a new one, with keys, from a Japanese dealership. I do wonder if they use canbus now for this instead a dedicated line between the immobilizer and the ecm.

      try reading the story.. youll look like less of a moron that way.

      The person you're replying to knows what they're talking about. Toyota keys on top of that are universally designed to be programmable out of the box, the only real problem that the shop locally might have is having the proper signal on file because it's an out-of-country vehicle. Even at that you can have the programmable ID tossed on a flash drive and go on your way or even emailed to you. There's also universal master-key signals, but they're not supposed to program them to customer keys. But nothing stopping the dealership to use it to get them out of the lot for example. There's the possibility that the key is only programmable while near the car, GM cars for example require this. But it's easy enough to trick the computer to broadcast the signal to the key too. All that involves is yanking the computer out and slapping it into diagnostic mode.

      It all sounds more like the dealership was trying to fuck them over fully, and they got more fucked in the end. The immobilizer ECU can be picked up for under $700 and comes with two keys, and that's through the most expensive source I could find.

    Why would anyone buy a car like that?

    According to TFA, they didn't know what they were buying. The car was originally made for the Japanese market, and later imported to Canada. They should have known something was fishy when they noticed that the steering wheel was on the wrong side.

    Also, according to TFA, it is common in Japan for car buyers to only receive one key, which cannot be duplicated. So I guess the Japanese just never lose their keys, or if they do, they just buy a new car.

    Add to that the fact that you can go to any dealer and get a key with the same code (which means the on-board software has no idea that it is different) for something like a few hundred dollars, and there is a bit of a fishy smell about this story.

    Are you sure this is true? I was under the impression that this was NOT possible. You CAN got to a dealer and get new keys - they just have to register them with the on-board computer. Which presumably they were unable to do in this case because they had NO valid keys? That seems odd to me too - you'd think a dealer could just reset the computer to zero and enroll some new keys.

    Also, the summary text is far more confusing than the actual article text. The fear of recharge related failure came from the mechanic recommending against letting a hacker at the thing due to fear that hacking it would screw up the computer as a side effect, not because the key was somehow vital.

    Terrible summary. And probably some stupid going on somewhere in the chain of events - I really don't believe a dealer couldn't have dealt with this somehow.

    The problem is the key and the computer were paired. To fix the problem requires either duplicating the key (but it was a custom system so that's out) or replace the computer with another one you have the key for. Biut when you replace the computer, THAT was where the charge cycles were stored, and the computer will think it's still using the battery from the vehicle it used to be installed in. (I suppose you could swap the battery too but that would be a whole new problem) The hack was replacing the computer and importing the battery data from the old computer.

    This all sounds rather odd to me, an electric vehicle you can't swap the battery on because the battery data is stored in the car not the battery? Any good laptop computer stores charge data in the battery itself, so a new battery has 0 cycles on it. You can also carry a spare battery with you and the computer can treat them differently. I don't see what sort of genius designs an electric vehicle and stores battery history in the computer rather than in the battery where it belongs.

    Many manufacturers are different.

    If you have 1 key, generally it's much, much easier (and affordable) to get a duplicate made. If you have no keys, generally your only route is the dealer for modern cars. Depending on the year and manufacturer, you can not make a new key from just the VIN. Ford specifically dumps their records after 10 years.

    I worked in a locksmith shop a few years ago, and every vehicle is different. Many manufacturers you can simply "clone" the existing key, and it will simply work without issue. Some other manufacturers you need to cut the key to a new key, and program the new key into the system. Sometimes it's as simple as turning the existing key in the ignition to accessory, leaving it there for a few seconds, turn it off, remove the key and insert the new key and turning it to accessory as well (most 2005-2012 Chevrolet's are this way). Sometimes you need to turn to Accessory 3-10 times for it to program, then you can start the vehicle with the key.

    Some need you to use an external device plugged into the CAN bus to program the new key in (many Fords, and Lincolns).

    When it comes to imports, however, all bets are off. We built keys, and rebuild ignitions to jimmy-rig systems together in some cases. You do what you need to do to make the customer happy. Our experiences were with older models, and nothing too technically advanced. Simple transponder based keys and ignitions, which are generally easy to work with.

    My personal vehicle uses a proximity fob, and they are much more complicated. Just as I left the locksmith shop, they came out with a way to clone the "key" part (you stick it in a slot in the center console to start the car), but not the proximity feature. If I wanted an additional proximity key, I would need to buy a new one from the dealer, and have them program it in to the tune of around $400. Thankfully I have two, but if one becomes lost I'll buy another without hesitation, as my body wouldn't be able to contain my anxiety I would have with the thought of losing the only key.

    It's a BS FaceBook Please-Fund-Me story. Any mechanic could've taken out the car computer and purchased a new one and installed it for less than $1500. Even if the car was out-of-country, it's a risk you take that when you buy exotic cars you may have to pay extra for repairs.

    I had an older Buick that had gone on the fritz where basically the keys would start the car but not unlock the gearbox or any other theft prevention (the radio would refuse to work, the car could not be remotely unlocked).
    My garage charged $500 to the warranty provider for a brand new "computer" and swapped out the keylock mechanism, and they simply reprogrammed my key (and then I had to go back with my other key to get it reprogrammed as well).

    And if I didn't want to pay the dealership an exorbitant amount, there are numerous websites that offer OEM-compatible key replacement and ECU reprogramming services including the Toyota Estima in the story.

    Think it can't happen? Hardware like that already exists. One of my friends has a Nintendo 3DS. He bought a new game for it to play in the car on a weekend road trip the night before we left, and ran it for the first time after we were on the road. The game came on cartridge. He put in the cartridge, powered up the system, and had a "fuck my life" moment when it refused to let him do anything until he downloaded an update. If he hadn't been able to tether to my phone, he would have been screwed and unable to play it for several hours. This was a CARTRIDGE GAME that effectively refused to run until it managed to connect to the internet and download something.

    I live in Japan and am super into cars.

    You usually get 2 to 4 keys with a new car, always 2 standard with fob/chip, often 1 backup key without fob/chip, and sometimes 1 "valet" key. When you get the keys you get a code tag that you use to order additional keys at any time - loose the tag and you can still order as long as you have an existing key, but you need to send the key in to have the tag info cross referenced. So basically as long as you don't loose the tag and *all* of the fob/chip keys you're totally fine.

    And the whole issue was due to the immobilizer, which was DOING EXACTLY WHAT IT WAS SUPPOSED TO BE DOING. The idea is it makes it very difficult to hot-wire a car, and even if someone does somehow (with a trailer?) steal your car they won't be able to actually use it or sell it without putting in a huge amount of effort.

    So what do you do if you loose all your keys and tag? You bring it to the dealer or an authorized/licensed mechanic who deals with that brand and have the immobilizer unit replaced. I just looked it up, and the cost for that on a newer Estima looks to be about $900USD.

    The dealer/importer should have been able to figure this out much easier but I'm guessing they're just one of those places that grabs cache stock from auto auctions and kludges the paperwork.
