I just don't understand why manufacturers don't follow Volvo on this - their keyless keys just go to sleep if they aren't moved for a few seconds, and they won't respond to any signal while sitting on a table for example.
My previous cars had keys that I could manually switch off and on, which is also not a full solution because it only works for people who take the effort to always do that, but at least it gives people to opportunity to complete prevent relay attacks.
All in all I'm not a big fan of key-less entry. Having to press a button on a key to gain entry can maybe be a bit of an annoyance, but in my opinion it's not a big deal compared to the advantage of completely preventing relay attacks.
>>the advantage of completely preventing relay attacks.
From my understanding ToF sensors are good enough now to completely prevent relay attacks, the added time for the relay just adds too much of a delay and it gets rejected. I believe the newest range rovers use that, they went from being extremely susceptible to relay attacks to relay attacks against them being impossible.
the real test is to find out if this effectively eliminated all fob hacks for volvo since they may not be faster than the tiger, they just need to be faster than everyone else...
If you’re car camping and doing a lot of stuff around your car and opening the doors a bunch for a couple hours, you probably want to put your fob to sleep. Found out the hard way, but my battery was also a bit iffy to start with that year.
Such common sense, yet so uncommon.
