Loving the tinted glasses you are wearing 1sttimer considering the tone of Mark Ns post before I had said a word. If you call it constructive then I guess we will have to disagree. Unlike MarkN I AM a RRS owner.

Interesting, the touch sensitive locking is designed to only work when the car can detect the key transmitting and it is outside the car, otherwise the car could easily be locked with the key inside. In the case of a normal non-keyless-entry remote, the key is normally off to conserve power; pressing a button emits a strong signal - hence the ability to unlock the car from a distance - and if this signal is jammed close to the car, the car will not see it and will not lock or unlock. Equally, because the key is emitting a strong signal, it's easy to intercept but I believe the problem of capturing the code to unlock the car has been fixed by using encrypted codes and maybe also frequency hopping so that the key transmits on a different frequency each time. With the touch sensitive locking, the key is not transmitting all the time because to do so would quickly flatten the battery. Instead, the key is listening and the car starts transmitting when you touch the door handle; the key wakes up and says "I'm here" and if the codes match, the car unlocks. The power output of the key is now much less since it has to be on repeatedly (though not continuously) - hence the "smart key not detected" message - to conserve battery power. Holding the key underneath the steering column (in the Evoque) wakes it up and may even (not sure) provide enough power to it through an induction loop if the smart key battery has failed. What I do not know is whether it is possible to jam the close distance transmission between the key and the car so that when you go to lock the car with the touch pad, it fails to lock. If you're doing that at close quarters, you're going to be much more aware of whether the car is locking than if you walk away and just blip the remote. A car with a locked door is at least some protection. So, the message is clear, make sure the car is actually locked when you walk away. The trouble with the keyless entry system is that trying the door handle to check will just unlock the car again. Mark SVR in Estoril Blue |

Thanks for the link, a rather timely article. The reason why so many manufacturers are affected is because they use a network bus to connect together dozens of small computers which talk to each other. If one wants to know what the outside temperature is, it can ask another which knows. When you open the door, the interior lights are no longer hard-wired to the door switches; instead, the computer in the door sends a message to the computer in the overhead console to switch on the lights. This is all to do with providing convenience features and reducing the amount of wiring but it means that a rogue computer can be connected and join the party. Switching things on and off, interrogate security codes, programming keys. Some cars use two busses - one for the general stuff and one for higher priority things like the engine management unit talking to the traction control system, of example. The ODB port provides just such a way to connect to the bus (sometimes called a CAN bus) and is there to allow dealers to exercise a car's functionality, obtain error logs, that sort of thing. It's also exactly why it's disabled in my Evoque and will be in my RRS when I get it. Even so, it is still possible to connect to the bus somewhere else in the car. By its very nature, bus connections are all over the place. Disabling the OBD port simply puts another obstacle in the way, just like a steering wheel cover As the Daily Mail article states (and I did in an earlier post), removing the ability to program a replacement key through the OBD port is key to addressing this problem but will make key replacement a much longer process. What I do not know is whether Japanese cars are similarly afflicted. I have the feeling that it's the German system with the prevalence of Bosch as a major technology supplier which is vulnerable; the Japanese have their own supplier axis and may do things differently. For manufacturers, there's a disincentive to do their own thing because many of the bought in parts - an air bag control unit, for example - will be designed with that standard bus in mind. Not that Bosch are to blame. Their technology provides the basic connectivity and messaging. However, somewhere in the car, there's a chip programmed with the unique codes of the car and a computer running some software which, in response to a request "download security codes", reads the codes from the chip and says, "here you are: 123456789......". All fine if that request comes from a legitimate source, less so if it's from some scumbag's laptop on your street at 3 in the morning. This is the area which needs tightening up, or removing all together, so that in response to the same request, the computer says "What?" Apologies for the long post. I don't expect my New Best Friend, Mikey will read it LOL. Mark SVR in Estoril Blue |

Thinking about this some more (night shift and it's quiet), there needs to be an additional authentication step by the owner of the car so that the software can obtain their approval: "I am only going to download the codes if the legal owner approves".

To be fair Mikey, I also said I find your almost taking offence when a word is said against LR a bit odd. Just to clarify, it is not my place to suspect/accuse anyone of being a troll planted by LR or a competitor and this is certainly not what I was suggesting. Just saying people should calm down and respect one another despite disagreements. |

I agree Fkarim yet the odd thing is when anyone offers a constructive argument to statements that are made, instead of jumping on the bandwagon suddenly they get berated? Just look at the accusations and claims of being psychotic simply because I said all cars can be stolen and no manufacturer of any product has any responsibility to tell you that people may try to steal it. Yet none of that is angry, it's all completely 100% accurate yet apparently I should be screaming blue murder about the people who make my car? I didn't when my BMW was stolen and wouldn't if my RRS gets stolen which obviously I hope doesn't happen.
