Keyless Entry

[MikeFish]

There were stories of code grabbers / extenders (or such like) that could read the code given off by your keys in your house and extend/ repeat the signal to someone next to your car to unlock the doors and start the car. Not sure how true it is but weighed up against the benefits / convenience the possibility was enough to stop me getting it.

I know they can be stolen because my last Audi got nicked and the fob is still in my desk draw!

Keyless is a well known vulnerability, not just with Audi.

Mike if that really be the case and I'm not disputing that this can't happen or hasn't in the past - but most stories you hear of is either someone breaking into a property to acquire the keys or being held up with a weapon!

[robf]

Yep, exactly what i thought too. Imagine my dismay seeing an Audi shaped dry patch on a wet road one morning!

[Y3CHR]

Given it is part of the reason why Audis can be nicked so easily, i didn't spec it on purpose.

This is the reason I didn't spec it. I almost specced it because the package also allows you to close the boot with the remote but I found a way to do this for free with VCDS and also close the boot from the door button.

Any chance of sharing how to do that?

I have heard those stories, too, but they don't stack up particularly to my mind. It's long and boring, but here goes: Like the standard car, a keyless car is continuously listening for a broadcast signal from your remote, in case you want to do it old-school style. If you use your remote in that way, then it's just the same as if you didn't have keyless entry, so no reduction in security from keyless entry in that situation.

However, if you do use keyless entry, neither the car nor the fob broadcast anything until a handle is grasped. At that point, the car pings the fob and the fob responds. Both of these signals are very low range - deliberately so in order to avoid compromising the security, otherwise someone could run up to your car after you have parked it and turned your back from it and open the door. So, in this keyless entry scenario, security is in fact higher than conventional locking and unlocking because the exchanged codes are broadcast at a much weaker level; to grab a code would require the thief to be right next to you.

Similarly, a thief would have to be right next to you to ping your fob and get a response that could be "stolen". It's possible, but they couldn't ping your fob if it were in your house and they were outside. And they can still grab the codes of conventionally locked cars from 50 metres away, so why not stick to the easy jobs stealing cars with conventional locking.

Thus, it could easily be argued that keyless entry is a safer system than standard entry since the keyless system user isn't regularly broadcasting a code to their car from 50 metres away.

Anyway, that's my logic from a basic understanding of the systems' operational methods. As I said, I did ask someone who knows and they said there is no compromise in security from keyless systems and, as I said, I haven't seen anything beyond internet speculation on this subject.

But how many people keep their keys near doors or windows? Not everyone but some people do. So one thief stands next to your car with a transmitter/ receiver. The other thief is next to your house door / windows with the other end of the transmitter/ receiver. Thief one pulls the car door handle, ping is sent through his transmitter to thief 2s receiver (and amplified). If in range of the keys and low power signal is picked up by Thief 2 and sent to Thief 1 and the car unlocks. If nothing happens then Thief 2 moves to another window etc. Seems quote straight forward and easy as long as you have the tech which apparently exists. But as I said before I don't believe everything I read on the Internet but seems a feasible thing to do and simpler than trying to generate or clone a remote key fob from a conventional locking system (doesn't need to generate code, just transmit an actual code).
But hey, I'm not trying to stop anyone from getting keyless entry, just explaining why I didn't get it.

Sure. Do you have VCDS or know someone that does? I've posted the instructions a couple of times on here but can dig them out again if you have the right equipment.

[Y3CHR]

Yes there is a guy local to me that does VCDS coding.

Thanks i appreciate it, your rapidly becoming my go to guy for this car haha

Mikes the go to guy for most things!! Including dead ho's,one armed gangsters and even dead horse heads. He is the MAN!!

There was a video of this on book of mugs so it's not a rumour it's fact that they have this tech/ method. They can't use the conventional method of smashing the window on a RS6 due to the laminated front windows then reach into the OBD so I guess they've had to think of new ways apart from hijacking. If I was ordering a new car now I'd go without advance key as well.

Good work Eddie, I forgot about that video; there are still people that will say it is unlikely or not possible but for the sake of pressing a button it was a no brainer for me. I have to press a button anyway to disable my aftermarket car alarm (with disabled OBD port too).

This is the instruction I found online. Every car I've done so far has already had these settings correct, so just make sure yours are set to these values first:

[Select]
[46 - Cent Conv]
[Coding - 07]
Click on byte 2, bit 2
Tick Comfort operation: Remote control active
[Do It!]

[Select]
[4D - Trunk Elec]
[Security Access - 16]
Input 12345
[Adaption - 10]
Activation using rear lid opening button in remote key - Touch function for closing
Change to ACTIVE
[Do It!]


Once you've checked both of the above items are selected check the following options and change to the values shown if not already set:

6D – Trunk electronics
Security access – 16 = 12345
Address 6D:4G9 959 107 A recoded (ADP-(4)-Activation using rear lid opening button in remote key-Tap function for closing) from not active to active
Address 6D:4G9 959 107 A recoded (ADP-(3)-Activation using rear lid opening button in remote key-Touch function for closing) from active to not active
Address 6D:4G9 959 107 A recoded (ADP-(4)-Activation using rear lid remote unlocking switch-Tap function for closing) from not active to active
Address 6D:4G9 959 107 A recoded (ADP-(3)-Activation using rear lid remote unlocking switch-Touch function for closing) from active to not active

This will result:

remote opening – long press - touch
remote closing – short press - tap
door switch – short press – tap

Touch = long press is set for opening to prevent accidentally opening the hatch.

I normally mess up on that bit as the option look so similar and the list above is not in the same order as they appear on the screen so it ca ntake a couple of goes to get it all working as it should. I should perhaps make a note of the order and rearange the list above to make it simpler to follow. Just make sure you select the right one each time.

If any of you are looking for something to protect the key whilst out and about here is an option. No involved with them, just trying to assist.
