good point, i have never tried this as do not want to lose keyless entry .
copied from another f-type forum so took it as being correct

 

Little story here.

About 2.5 yrs ago I parked my '12 XJ, in the (new to me) Rec Center car park. It was about the same temp outside as a Hades winter, wife and kid are unloaded and head off to get our new pool passes. I park, get out, and attempt to lock the car. Nothing. Car will not lock using the door button, key fob, lock button inside, zilch. I locked the car using the emergency blade key and walked across the road to get a new fob battery....again nothing works.

Long story short, car gets towed to the local dealer, they reprogrammed the keys,KVM and all was good. When I asked what had caused the problem they speculated that someone was in the car park and trying to steal my car, by a clone device, and that they corrupted my KVM in their attempt. If I hadn't noticed that the car didn't lock, they would have been able to access the car and then start it using SDD via OBDII.

My insurance paid for everything!

Pls explain KVM ?

 

Are you asking what it means/stands for or how it works?
Coz I can help with the first but not the second!
It means Keyless Vehicle Module.
Which I presume means it is one of the eleventy million electronic modules in the car and it controls keyless entry and locking.
After that I am clueless.

 

I think we've identified two risk scenarios here.
The first is thieves using a scanner to pick up and amplify/rebroadcast the proximity signal from a fob and use that to enter the car with keyless entry and start the car. This could happen at home, a motel, your office, or anywhere the thieves can get close enough to your fob to pick up the signal. The solution is faraday bag that you can buy online for about $12 for a pack of two bags.

Question. Is it true that this proximity signal could be recorded by the thieves and replayed even when your fob is nowhere near the car?

The second risk, if I understand the comments above, is that the signal sent by pressing the lock and unlock buttons on the fob can also be intercepted and replayed. The "solution" for this is keyless entry, don't press the fob buttons, just press the handle itself in or the button to unlock. This reduces your risk, but does not eliminate the possibility of the proximity signal being hacked by someone next to you in the parking lot.
Is this an accurate summary? Thanks.

 

I don't think that the second risk applies to modern Jags because they have a rolling code.

I remember reading this a few years ago:

https://www.stuff.co.nz/motoring/new...ck-finds-study

But if you can't be bothered to read it this is the interesting bit:

"The three models that withstood all attempts were Jaguar Land Rover vehicles – the Jaguar I-Pace electric car and latest versions of the Land Rover Discovery and Range Rover."

 

Interesting report. 2019 vintage. Sounds like we may be OK on that front. Does anyone know for certain if Jag uses rolling codes for F's, and when they started doing that?

I ordered a set of faraday key fob pouches, $12 on amazon.

 

Is it the vehicle that has the rolling code or the opener? When I was trying to get my opener to play nice with Homelink, it appeared that only the openers have the rolling code feature.

 

Hmmm, on the other hand:

so best risk management is using keyless entry and not pressing the fob when away from home and when at home and in the office having your keys in a faraday pouch or tin. $12 or so for a little bit extra piece of mind isn’t too bad and not too paranoid either.

 

I suppose I must be paranoid then!
I bought a pair of Faraday pouches a few months ago and the fob now goes in one when not in use, The other/spare fob remains disassembled with no battery together with the spare pouch, hidden away in a "secret" table drawer.
The car is always double locked (to prevent battery drain) and parked in the under-main-roof garage with a secure electric roller door, with the door remote semi-hidden inside the car.
So no way any dodgy ****** are stealing my car without a fight!
I suppose of course they could smash through my front door, hold me at gun point or knife point, and demand the fob from me.
Then they would have to figure out where I have secreted the garage door remote in the car but even a nitwit should be able to find it without too much trouble.
Given these simple precautions and the fact that I don't live in a rough neighbourhood I have peace of mind that my car is safe.

 

There are lots of ways to steal a car, and lots of ways to guard against it, but it depends a lot on the potential thief in question - how sophisticated they are, how much of a full-time gig this is, and how much money they are willing to spend upfront on car theft gear.

Casual thief isn't going to steal the F-Type, they'd be foiled by the rolling code keyfob. They might bust a window and rummage through for valuables. To prevent it: park in safe places, park in well-lit places, don't leave anything inside that they can see.

Next level - they can read and repeat the keyfob's signal (the passive one, or the active one from pressing a button) but they can't defeat the rolling code (ie: they can't predict what the next code will be). So they use your keyfob without your knowledge, by using a repeater like the story above (and an accomplice, which already makes this a more organized and planned theft) or by straight up stealing your keys. To prevent it: keep your keyfob somewhere they can't casually read it when you aren't using it, including in a faraday bag (which you can buy on Amazon) if your house layout makes it possible to read your keys through an outside wall.

Professional level - they can read the keyfob's signal and calculate the next code in the rolling sequence. They have professional tools and probably hunt specific cars they have a buyer for. These are the ones tracking your car looking for the right moment, because they can unlock it whenever they want. To prevent it: keep your keyfob secure to give them fewer chances at reading your unlock sequence and park in secure places. And then just make sure it's insured and don't make a big show of where you store it at night . If they want your specific car there's not much you can do but if your car is less convenient than another one, they will rob someone else.

There's no point in making yourself hyper-paranoid or doing a bunch of really cumbersome things to protect your car, just have a few good habits ("all keys go in the faraday box on the hall table and close the lid", etc.) and that makes you leaps and bounds less convenient to rob than the house down the road.

 

Thank you for a superbly written and described piece that puts much in perspective. While I had purchased a Faraday bag for the 2018 corvette and HAD used it regularly when having the car out, had gotten lazy. But I do store the key fob in bag, in house, yards away from the car. Also lazy with the F. Guess I felt it wasn't so serious anymore, always park it in a garage at night, key fob in house at a distance. Having read this thread, purchased additional Faraday bags and will be more mindful about using them. No sense it making it easy for thieves.

 

Yeah I think it's a simple step that's worth doing, just make it easy for yourself and make it a habit. The bags are cheap, and there are also nice wooden faraday boxes that look appropriate on a hall table or other "normal" ways like that to store your keys, so it can be easy enough for you that you do it most always. The professionals driving through the neighborhood looking for stray signals won't get anything from your house and will just move along.

 

I do as schuss suggests and keep my key fobs in a box like this on a shelf near the stairs where keys, outgoing mail and those types of items are often found in a home


A friend mocked me for having a special box "just for the keys to my Jag" until I explained what it was and why it was necessary.

 

Has anyone tried this? I just gave it a try on my 2018. It did not work.

 

Some car manufactures are designing the key fob to only transmit when it is moving, like when you are carrying it in your pocket.
