This came in handy for me once when I locked myself out of a u-haul in what used to be a rough neighborhood in New York. I was standing there fishing with a coat hanger trying to figure it out when a gangster looking dude came up and was like "here, let me help you with that," and 3 seconds later had the door open.

Haha similar story. I used to deliver pizzas and worked with a pretty rough crowd. Once I locked my car while it was running and had a bunch of deliveries. One of the cooks unlocked it in about five seconds.

I have a similar story! Locked out of my car. Bikers park next to me.

"You locked out? Hang on a moment"

Goes into a Subway, comes back with a coat hanger.

Less than a minute later the car is unlocked.

"Wow you're pretty good at that"

"I literally just got out of prison today... for car theft."

Laughter all around

Who knew there were so many Good Samaritan car thieves out there, huh? I guess everyone enjoys a chance to show off their skill set a little!

I locked myself out of my car so often I ended up wedging a coat hanger under the rear bumper. You're right: car doors used to be trivial to yank open when you knew the trick. These days I'd love to create a little side project that sets the alarm off on my car any time a relay attack is detected. I'm sure Mark Rober or someone will end up doing it.

Wouldn't it have been easier to put a second key under there?

Of course, but that takes time and money to get a new key made. And once you know the trick it’s trivial using a coat hanger.

sounds rather complicated. You would have to scan the entire spectrum (not the entire, but like certain bands) and detect if there is someone sending power on there.

But modern vehicles detect these relay attacks and drop your message when you are too far away (ToF Measurement), you could maybe instrument that. But then when you walk to your car on an open field, you may also trigger the alarm because your key is out of range for a short time.

what would the alarm do other the annoy a few hundred people. It wouldn't save your car. car alarms should be banned imo. replace them with something that pings your phone maybe but the alarm does nothing

There are alarms with phone messsaging, tracking, remote start and disable. Also relay attacks are easy to prevent, just put your smart key inside a faraday bag or remove the battery.

Not a great analogy though, since a coat hanger’s primary use is not to break into cars.

Note: I’m not advocating banning the flipper zero anymore than I’d advocate banning lock picks. I just don’t think the analogy is apt.

And a Flipper Zeros main purpose isn't to break into cars either...

It’s really hard to determine the primary use of an item, especially for legal purposes.

Intentions sometimes matter. There is a South African shotgun aspirationally named Street Sweeper, and it's famously classified as a Destructive Device in the US, which is two levels more strictly controlled category, AIUI, IANAL, than a manually operated Gatling gun.

FZ is intended to clone keys and bypass security, I suppose in significant part for users' lawful convenience, but is kind of intended to do what it should not.

Coat hangers aren't engineered with intent to be shoved into the weather seal on a door.

You can literally order lock picks on Amazon in Canada[1].

Which were absolutely engineered with Internet to be shoved into locks to open them without a key.

To be clear: purchasing ans owning lockpicks is perfectly legal in Canada [2].

I don't think your logic applies to why that legislation was introduced. They're treating Flipper as a lockpick, but legislate it differently nevertheless.

Cheap, misguided hype seems to be a more plausible explanation.

> FZ is intended to clone keys and bypass security

I'd say it's more of an educational/'hacker' toy than it is a useful security bypasser/key cloner.

Purpose built(and better aot their job) those things cost significantly less. The flipper zero is a toy that the Canadian government are about to misclasify.

There is (was?) a tool called a slim Jim that was basically a purpose-built coathanger for unlocking doors.

There was some talk of banning them in some areas, because people love treating symptoms rather than causes.

Nowadays the tow truck drivers have a little inflatable bag they slide into the top of the door and inflate so they can press the unlock button from the inside. Quite effective!
