“Sleeping Batteries”

MarkMas said:
Well, much more sensible, but I suppose not easier or cheaper. Easier to send out a few batteries, than to recall and replace thousands of fobs.

I guess another solution would be to send out some sort of compression switch to sit next to the normal battery., so you have to squeeze the fob to make the connection. Would that work? Or, duh, have a fob with a button.

Yeah, I think it'll be the next gen fobs that sleep automatically. Sort of what I meant. Easier if you're designing from the ground up. As for cheaper, I assume you looked at the price of the batteries? :O

So I have a 2022 Velar now but when I walked up to it, it doesn’t do anything. I have to press the physical buttons on the key to operate.

So I assume the keyless system is off?

Do I need to do anything further to protect myself?

Buy yourself a Full Fat P38 Matt.

If you don’t click the fob on my XJ you have to press a button on the door and then the car will start “keyless” - I suspect yours will be the same.

So you need to faraday your key or they can “boost” the signal to unlock and then start the car.

Yes, indeed; mine hardly unlocks at all, whatever you do.

Post in thread 'Range Rover advice'

I've been having some trouble with the key fob and central locking on the P38, with the main fob intermittently working, and sometimes not disabling the immobiliser. The 2nd fob has knackered buttons, but the chip works.

I thought I would start by replacing the batteries, but the battery door is made of the sort of cheese that (a) sticks fast to the fob, and (b) has a very soft indent for a coin to turn it, which had already been destroyed in the past (on both keys).

Suggestions on the interweb included drilling two small holes and using 'pin pliers' (new to me), or heating...

Land Rover has updated their system. It is quite safe now. They have changed the way how the car authenticates the key’s signal.
It now looks for distance from the fob as well. Meaning if the key is not inside the car, the car can’t be driven away.
All the Land Rover Made from middle 24 have this additional safety measure.
Relay attacks are unlikely on this models. Anything between 2018 and 2024… God help the Insurer…

Define safe...
How far is too far...
And why didn't they do this in the first place?
One for the lawyers
 
Yeah because it would take sooooooooo much more time and effort to steal (for example) @philw696 's car

£2500 worth or electronics? Nope
An accomplice? Nope
Possibly a couple of screwdrivers, some wire strippers and 20 seconds or so.....

If thieves are determined to take a car, they may succeed. However, when defeating the security takes too long, they usually abandon the attempt and move on to an easier target.
Relay attacks are ineffective on vehicles equipped with UWB keyless systems, which makes this method secure.
Instead, thieves typically attempt to access the vehicle’s CAN bus, often by reaching the wiring behind a headlight. This method can unlock the vehicle without triggering the alarm.

Mrs C's cousin had his Giulia go by this method.

I still maintain it probably took them longer than a coat hanger and a screw driver. Not *much* longer, perhaps...
