    Default Hacking car remotes

    Has anybody come across this yet?


    I locked my car. As I walked away I heard my car door unlock. I went back and locked my car again three times .. Each time, as soon as I started to walk away, I would hear it unlock again!! Naturally alarmed, I looked around and there were two guys sitting in a car in the fire lane next to the store. They were obviously watching me intently, and there was no doubt they were somehow involved in this very weird situation. I quickly chucked the errand I was on, jumped in my car and sped away.. I went straight t o the police station, told them what had happened, and found out I was part of a new, and very successful, scheme being used to gain entry into cars. Two weeks later, my friend's son had a similar happening....
    While traveling, my friend's son stopped at a roadside rest to use the bathroom. When he came out to his car less than 4-5 minutes later, someone had gotten into his car and stolen his cell phone, laptop computer, GPS navigator, briefcase.....you name it. He called the police and since there were no signs of his car being broken into, the police told him he had been a victim of the latest robbery tactic -- there is a device that robbers are using now to clone your security code when you lock your doors on your car using your key-chain locking device..

    They sit a distance away and watch for their next victim. They know you are going inside of the store, restaurant, or bathroom and that they now have a few minutes to steal and run. The police officer said to manually lock your car door-by hitting the lock button inside the car -- that way if there is someone sitting in a parking lot watching for their next victim, it will not be you.

    When you hit the lock button on your car upon exiting, it does not send the security code, but if you walk away and use the door lock on your key chain, it sends the code through the airwaves where it can be instantly stolen.
    This is very real.

    Be wisely aware of what you just read and please pass this note on. Look how many times we all lock our doors with our remote just to be sure we remembered to lock them -- and bingo, someone has our code....and whatever was in our car.

    From eBay....

    Detect, receive, copy all kinds of car remote control signals, then command the car as freely as the carís owner
    - Working frequency range: 305~330MHz
    - It receives the signal sent by the fixed code anti-theft system, save and copy the masterís remote control signal
    - The effective distance is 100 metres

    Eish.

    So my old school, mechanical, "draad en tang" approach is still the best.

    Does the copying of the signal also apply to the systems using "code hopping" seeing that the copy made is from a now defunct signal and the next one should be different, not the same?

    So much for 'keyless' systems! The newer 'hopping code' systems should overcome this problem provided these scanners are not clever enough which I doubt! Some cars don't activate the alarm system unless it's set via remote so locking the car via key is not always the best. Here the infrared 'point at receiver' remote system is maybe safer.

    very scary stuff.... not just in being burgled... but it opens a doorway to others waiting for you inside the car.

    My Colt's remote is so weak, you have to stand right next to the bakkie to be able to lock/unlock it...

    same story with my Jetta


    On the other hand my owner's manual says that encrypted communication takes place between car and remote and that the signal security code is scrambled every time it is used.

    OR worse they UNLOCK the doors for you in your driveway.

    Code hopping is the way to go. We have recently upgraded all our remotes in our complex to code hopping. i have a security gate between the garage and the house for exactly this reason. garage door is one of the easiest to copy.

    Should be simple to upgrade your cars system, the wiring is already there, just a better remote and receiver...............IT SHOULD BE

    Wonder what the insurance has to say about replacing all your stuff without any forced entry signs. With their track records they will probably say the police are DREAMING.

    Holy smoke!

    Cloning of remotes like this was a big thing about TWENTY YEARS ago.

    That's precisely why rolling code (aka code hopping) remote schemes were invented.

    (South African invention, by the way, now used the world over.)

    I am in the security business and I am not aware of anyone having cracked rolling code technology. I'm pretty sure it would have been discussed in many different security journals and Internet forums if it had happened.

    I therefore assume that the remote control system in this particular story is the much older fixed code type, which is amazing - I had no idea any vehicle manufacturer still installed fixed code systems.

    Picking up the signal from a fixed code remote and then copying it is very easy and has been happening for a couple of decades already. Nothing new.

    Usually you don't find any fixed code systems on vehicles although many remotes used for gates and garage doors are still of the fixed code type due to the cheapskate nature of the SA public who would rather save ten bucks than have decent security.

    Few months ago I locked my bakkie door with the remote and heard the Caravelle parked next to it unlock its doors.
    Came back later and the Caravelle was still there. Unlocked my vehicle and the Caravelle answered with a flash but I couldnt hear doors locking.
    Happened again a few months later at the mall with an Audi parked two cars away. I press the button, the Audi howls. Had fun for awhile.
    Explanation? Naw, not from me.

    Of course is an SA invention - all good security inventions are!!

    There was a recent claim from someone in our neighborhood watch community that the Hummer remote was found to be able to open certain types of gate Motors. I assume these are the transponders that don't use code hopping. I will see if I can locate that email. Specific mention was made of the "vulnerable" transponder boards.

    Greetings - I respect this is an old thread, also not sure if there are other more current threads to this, and if so please accept my humble apologies.

    Just over a year ago in the (very busy) parking lot of Raslouw Lifstyle Centre (next to the Mall @ Reds) Centurion, we arrived back at the car after about 10 minutes in the shop at around 17:15 on a Friday - unlocked the car, got in and went home. Only on the way home did we realise cell phone, camera, GPS was missing from the center console box. Nothing we could do.

    There is a fair amount in the media which mentions that crinimals also use specialised electronics and gadgets which the dealers have. This puts vehicle owners in a bit of a predicament and opens other untoward channels such as those bad apples that will take advantage in other ways. Time to weld a big old padlock onto each door it seems.

    A little off-topic "maybe", but the few times I have been in these big electronic supply shops, I have often wondered about the devices and circuitry bought by some customers - highly opinionated and unfounded of course, but I seriously have my doubts. As they say "Africa is a tough country".

    Don't need sophisticated devices to "open" cars with lately. You can try this at home, it works.
    When you walk away and push your lock button on your remote, the car will never lock if someone close to you have a regular, every day gate or garage door remote that they push and hold. This "jam" the signal from your remote to your vehicle and it doesn't lock. You think it is locked and walk on and the bad guy comes, opens the door and does his affirmative shopping.

    The South African invention is called Keeloq: http://en.wikipedia.org/wiki/KeeLoq

    A couple of mates got together at work and did this on each other's different cars to which ones it works on and which it does not. Very interesting and amusing for what a bad thing is worth. good eye opener for people to see the actual risk under safe conditions

    My standard gate remote so far jams any vehicle I have come across locking signal.
    Just hold it down and the vehicle does not lock up to 20 meters away.
    Although it does not impact the Netstar system as this works every time. Tried to jam it with some "other equipment" and it still works.

    Seems to lock your vehicle you must key it and then push the remote to activate the alarm. Else have you Netstar wired to the locking gadget and alarm system.
    Some manufactures does not allow this and with the GM products it is not possible - so far?
