A lot of the newer cars with prox keys have a feature to temporarily disable the prox transmission from the key fob. That means amplification attacks don't have a signal to amplify.

For example: A lot of Subarus and Toyotas can be disabled by holding the lock button and double-tapping the unlock button. It's then reenabled the next time you click the unlock button.
I didn't realize how many owners were unaware of this capability until some recent conversations so hopefully this can help someone.

@cR0w uh... this seems like a bad idea to hide security features in an undocumented way.
"oh, you can be safe by going up up, down down, left right left right A B start"
-
@[email protected] @[email protected] it is LITERALLY documented in the manual, idk what people want from the world lol
-
@froge @risottobias @cR0w Have you looked at a car manual? Hundreds of pages of fine print, most of which you'll never need for the entire duration of owning the car. (Seriously, most could be cut down to "use this amount of oil," "use these size bulbs in components x, y, and z," and "these are the fuse listings." Maybe one or two other things, but you get the idea. Like 30 pages instead of 400.)
But this is pretty darned important. It should be labeled ON the keyfob probably.

@[email protected] @[email protected] @[email protected] the keyfob usually has a 3-8 page manual, I read them, idk I guess most people just don't bother looking at the documentation for their fancy new $50,000+ car???
but like even if it IS only documented in the long ass car manual, flip to the keyfob page and just read a few lines instead of wasting time on the oil pressure section that you obviously don't care about, manuals have an index/glossary for a reason lol
besides the point is that this IS literally documented in the actual literal documentation for your car, saying it's undocumented is just flat out wrong in every way I can imagine, just because it's not dead obvious, or because people don't actually read things, doesn't mean it's suddenly undocumented lol -
@froge @risottobias @cR0w How is someone who got a car going to know that they even need to read manual entries about their keyfob? It's a keyfob. Who expects it to have hidden features?
Again, such a thing is surprisingly simple: just print it on the back of the keyfob.
-
@[email protected] @[email protected] @[email protected] you always need to read the manual for the things you buy, not doing so is literally negligence, idk what else to tell you
Yes it's surprising they have this feature, but I'm almost certain it's just because people aren't reading things, wanna know how you're supposed to know your keyfob can do this?... read the manual that explains how your devices works, it's very simple, they don't actually hide these things lol -

@froge @nazokiyoubinbou @cR0w I can tell from your defensiveness you know it's right. Bad design and bad documentation is a disservice to users.
Good UI design makes sense to users, is familiar, and small indicators and hints help expose parts of the interface.
People don't read "how their keyfob works" and I think you should understand this.
They don't read how their signaler works, or their window controls, or their speedometer. Those things have small labels and simple functions. they intuitively start using them.
