Can the VF passive entry system be hacked or is it safe?

[stooge]

It's great in theory but likely the law may take a dimmer view of you using your illegal signal jammer than they would of those low life theives who stole your car

yeah but is it "illegal" because you are broadcasting on a legal amateur frequency, don't confuse this with something like a cellphone jammer.
it would come down to how you go about implementing the signal strength or "EIRP" which according to acma must be "25mW" or below and how much interference it creates.

anyone can test it or make one even, just get a simple garage door opener like this one and pin the button down so it is always transmitting.
while it is transmitting the vf will not be able to use the pkes part of the key or the remote lock/unlock depending on signal strength to the vehicles receiver.

would a acma approved remote with the button pinned down be illegal?
it would depend on the complaints I guess lol

Identify the frequency https://www.ebay.com.au/i/323411667633

Replicate the sign depending what frequency it is transmitted on.

As long as your key transmitter is out of range of the frequency counter your safe.

There doesn't seem to be any issues in Australia, at least not widely reported
But see this video

One bloke walks up to the front of the house with a scanner. The other bloke stands near the car door with the receiving unit and bingo,they get into the car. In this case they needed to do it twice to get the car going but like it says, GONE in 60 SECONDS!

The device the guy at the door is using is a repeater. They are picking up the signal from the key transmitter and repeating / transmitting it to the guy at the car. Once he had the signal he was in. Im guessing the device saved and stored the frequency for further use and to reprogram another key.

Well there you go, we do the same, park the wife's Daily behind the garage with the Redline in it, keys live in a safe.... Literally in a safe lol. Drive it on the weekends so... No an issue to dig them out once a week.

Just when you thought you were safe from the old PKES relay attack, seems a new attack vector has been developed to pinch you pride and joy

This new attack is called “CAN injection“ and on a RAV4 it involved accessing the headlight wiring via the wheel well and then connecting a small cheap device to the can bus lines. At that point the vehicles network is spammed by crafted signals and they can then open the door, press the start button and drive off… all can be done within 2 minutes.

There’s a new form of keyless car theft that works in under 2 minutes

As car owners grow hip to one form a theft, crooks are turning to new ones.

So the tin foil wrapped key may no longer help to protect your car

Worst thing is … if they were willing to stoop to stealing a RAV4, they’d be happy to thieve anything!

I wouldn't be concerned with it.

I was recently reading several online articles about how cars with passive entry/start systems (like some VF models) can potentially be hacked - i.e. unlocked and driven away without the keyfob.

These two 2015 articles discuss it in detail:
https://www.whichcar.com.au/news/keyless-entry-hacked
https://practicalmotoring.com.au/car-advice/why-your-keyless-car-is-vulnerable-to-attack/

And an overseas article from 2017:
https://www.tomsguide.com/us/keyless-entry-car-hack,news-25022.html

Yet this NRMA arcticle from 2016 is a bit more positive saying it’s not an issue in Australia:
https://thehub.nrma.com.au/drive/have-keyless-cars-become-target-thieves

So I was wondering are VF’s with passive entry/start safe?

Just a silly question but would a cut off switch to the fuel pump work?

yes but its not necessary.
