reminder, these vendors like Volvo etc., don't really want you to report vulns, you should just sell them to a broker instead and get some actual money as well, it's a win win.

I don’t know why particularly here over elsewhere, but this thought really makes me feel disappointment in the whole chain of humans responsible for the cost optimization away of product integrity.

Though in this case, with all the tracking being thrown into newer cars, maybe a bit of a gap is a good thing for the future. Jailbreaking vehicles would be a cool thing to see become widespread.

This is my primary concern with modern cars. You are at the complete merci of the security and correctness of the cloud management software for the correctly functioning of the car.

Wouldn’t it be better if your phone/devices would pair directly with the car, exchange keys, and have the company cloud only function as a proxy.

On holiday a guests BMW didn’t want to “start” anymore because it couldn’t phone home because of lack of phone reception. They had to contact the dealer at home and move heaven and earth to get some dealer code to allow the car to start again for a while. Why is this even allowed?

by spockz

7/27/2026 at 7:27:49 PM

Agreed that it's absurd. Consumers continue to purchase cars that do this though. BMW doing this, having proprietary bolt heads, and the subscription heated seats fiasco from nearly a decade ago have made it clear that BMW is a make that will try to screw you at every turn, yet people continue to purchase them.

It's a shame. I will continue to purchase vehicles with as internet connected and touch screen features as possible. My 2025 Toyota has knobs and a physical key still. Terrified what will be left on the market when I have to get a new vehicle in (hopefully over) 15 years.

by jjice

A lot of people don't know anything about any of this. They don't even understand what the difference between something like SYNC or Android Auto is. And the manufacturers subdue as much information about these things as possible. Outside of the automotive enthusiast and now increasingly the tech space, there's no discussion or spread of awareness about these kinds of hostilities built into vehicles.

So yes, people continue to purchase car that do this because they don't know they do this. And if the manufacturers have their way those people will never know until it's reared up and bit them.

Surely there's more to this story? AFAIK last time I heard about something like this, it was because the guy's car was parked 5 stories underground, and didn't carry his car keys, because he was using his phone to unlock all the time.

I hope you aren't suggesting that set of details makes this okay. I should be able to park in a faraday cage 2 miles underground and still start it the same as I can on the surface. Including with my phone, if it's equipped with phone-as-key.

The phone-as-key shouldn't only work when online and shouldn't require the car to be online, either. And this is a problem trivially solved with proper use of cryptography.

The reason for this is that if the car gives people the ability to start a trip with a phone, it's dangerous to assume they'll always carry a keyfob as a backup. Just like I don't carry two car keys.

by xp84

7/27/2026 at 7:44:57 PM

It doesn't; BMW use the CCC Digital Key standard for "Digital Key Plus" and there's no Internet required post provisioning. This story really reeks of misunderstanding or "needs more information" as for BMW especially, I don't see any scenario where this could have happened, regardless of physical or phone key use.

by bri3d

7/27/2026 at 9:13:24 PM

It's possible they were trying to do something like remote start, which (at least in my bmw) does use the godawful bmw online service. In the retelling, this might have expanded to "couldn't start the car."

How's this any different than say, not bringing your wallet with you, because 95% of the time apple pay works, and then getting mad at the shop/credit card company/apple when the payment terminal randomly decides to not accept apple pay? Not to mention there are plenty of other ways a phone can fail. It can fall into a toilet, you can drop it and the screen cracks, etc. By not carrying the keys, you're rolling the dice every time.

>Just like I don't carry two car keys.

That all depends on your risk appetite. I normally wouldn't carry money in my socks, but if I'm in a foreign country I very well might. Likewise if I'm going on a road trip where I might be days away from home, I very well might bring a second key, in case i accidentally lock one in the car or whatever.

ApplePay doesn't communicate with Apple through your phone, it presents the card details as a contactless EMV transaction through the card reader, so it's pretty much spot on as an example of how this should work.

Just so you know, EMV can work entirely offline if you need it to, because the reader has the public keys that the card requires to authenticate and vice-versa. ApplePay uses the same NFC standard as regular EMV contactless cards to communicate, it just happens to be a powered microprocessor instead of a radio-powered microprocessor but that's about the only difference. The smart card standard is really old and covers the exact use case of "what happens if I need to use this thing without the Internet because the Internet wasn't ubiquitous when it was developed.

by throwway120385

Back when I had an Apple Watch, I failed to use Apple Pay on it enough times due to it being stuck in an "Updating cards" mode, so GPs "95% of times it works but sometimes you need a fallback" rings true to me.

by kalleboo

7/28/2026 at 5:28:53 PM

That's surprising. Of all the Apple Watch's many failings (such as its hilariously bad transcription) I've never had Apple Pay not work flawlessly on it. One of the main reasons (the other being the "make my phone loudly beep" button) I even bother having one, the rest of the features being so underwhelming for its price.

by xp84

7/27/2026 at 8:11:16 PM

It's very different, because you aren't moving from car to car. You're using your car with your digital key. There is no expectation of things changing. Rightly so.

Apple Pay involves at least a third party (your bank) as a part of its function. This entity has to be reachable.

Unlocking my car needs me, and my car.

> when the payment terminal randomly decides to not accept apple pay?

I would be justified in being mad if, randomly, my BMW car would decide to not accept a BMW key (virtualized or otherwise).

> Not to mention there are plenty of other ways a phone can fail. It can [...]

"I will not accept this Euro bank note. You could have dropped it into the gutter on your way here, so it's strange for you to be mad at me if you don't have a backup."

by esterna

7/27/2026 at 9:12:05 PM

The point isn't that it's fine for smartphone car keys to randomly fail, it's that there's plenty of other reasons they can fail that you're already living on the edge if all you're carrying is your phone. Therefore the "it's dangerous to assume ..." claim doesn't hold.

by gruez

7/28/2026 at 5:38:23 PM

> there's plenty of other reasons they can fail that you're already living on the edge if all you're carrying is your phone

I see what you're arguing, but I just want to point out 2 things:

1. If I leave the house for a trip (especially a distant trip) with just my phone, I and anyone would understand intuitively my own responsibilities: namely, to keep my phone intact and its battery from draining completely. Since I already have a strong interest in both of these for other reasons, this is basically automatic anyway, and a backup plan for the latter is completely doable - I'd have to drop $20 on a gas station phone charger and hang out somewhere for 10 minutes while it goes from 0->6% or whatever. Anyway, if I understand my responsibilities like this, I'm able to make an informed decision on whether to trust it.

2. If we're victim-blaming here, saying "Serves him right, should have carried the keyfob as a backup" that renders it pointless to even have phone-as-key. The fob not having to be in your pocket or handbag is the only benefit. Unless, I suppose, you consider phone-as-key as the actual backup, for use only in the case you drop your keyfob into a storm drain. But that isn't how it's marketed at all. In my entire life, I've literally never lost my car keys, because they just stay in my pocket the whole time I'm away from home. So I'd value a 'phone-as-backup' at $0.

No it doesn't. It has to have a recent token, and if it does not it will contact your bank.

by dotancohen

7/27/2026 at 8:50:38 PM

In this case it was with car keys and the valley where they are parked has no cell reception at all. Apparently they could still enter the car but not “start the engine”. They then managed to get a code from the dealer to unlock the car. I’m unsure whether it was a software bug relying on communication unnecessarily, a intended feature, or something like an alarm being triggered which triggered some fail safes.

by spockz

7/27/2026 at 6:53:56 PM

How they will be able to block you from using your car when they deem that you should by a new one? Or how would they be able to make something a paid feature after you bought it? You need to support these poor fellas

That is admirable, though of course it should be a legal standard, and there should also be legal standards for building features in a way that allows you to use them when your data collection is disabled.

Disabling data collection shouldn’t disable entire major features like lane centering and navigation. Even tech giant spyware companies like Google offer offline maps.

You can disable connectivity in any car by pulling fuses.

Yeah but sometimes that disables other things too. Like when I pulled the fuse on my car for the radio, it disabled the power door locks and the door/headlight chime. Not every item gets it's own circuit.

No wonder a few weeks before few BMS apps based on BT was banned in India as they were misused for remote disabling of e-Rickshaws.

Securing BMS should be the top priority for EVs. Keeping unsecured BT connection in BMS would be the worst thing.

by tesnorindian

I was recently researching building large LiFePo4 battery banks and realized just about every BMS I looked at featured a BT connection. That was disappointing as I assume there is little to no security for pairing ans communication. Anyone could sabotage or shut down a battery bank.

There is security that protects users and then there is security theater that provides litigation protection for the company.

Sometimes overlapping, but they are not the same thing.

by Xeoncross

7/27/2026 at 7:04:20 PM

Both are important actually, the security theater often deter from trying because it could be too annoying, it's generally "free to do", along with additional obfuscation, it's useful too but does not replace proper security, but from experience, theater+obfuscation+security is greater security than just security.
