That solves part of the problem, but doesn't help when you're in a supermarket or any other event where you're moving around.

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.

My previous car(a Mercedes) had a very very simple solution to this - you clicked on the lock button twice and it just disabled the keyless entry entirely until you pressed any other button.

>>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.

I think the Toyota has it too. Press and hold lock and click unlock twice on the FOB. This disables the signalling that enables a lot of 'quick actions' - like double tapping the door latch to open it.

that's a nice solution too but re: mercedes it requires the user to actively use that feature which I suspect most won't remember to do

For anyone interested, with all keyless entry Subarus in the US it’s easy to put the fob to sleep.

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.

maybe so, but this would seemingly solve most of the problem with easy to implement tech

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...

Related: I've found that replacing/programming Volvo keys is extraordinarily expensive and I've yet to find a third-party locksmith who will touch them. (The latter applies to both fobs and a basic key.)

Yep - which is why I always add key insurance to my car insurance, it's a very cheap add on annually but saves a lot of money if you need a new key.

Wow. I had no idea this was an option. It kind of breaks my brain a bit because, based on the majority of my experience with car ownership (91, 98 and 2K models), it's an absurd notion.

Likewise, I wish my phone had a setting to mute Amber Alerts while the phone's been motionless for a long time. It's sleeping, I'm sleeping, blasting me with an emergency tone at 4:45am is not going to help anyone. But yes if I'm actually out and about, by all means, I'd be happy to help, I don't want to turn them off entirely.

Such common sense, yet so uncommon.

I've heard BMW does it too. Hoping that it's true and I can preserve battery by just keeping my key on the table, since it burns through a charge.

Phone based keys leapfrogged this

Except phone based keys are terrible in many other ways
