    Default Car jammer at the office. Is there any hope?

    Today, car jammed, and liberated from expensive medical gear. Feeling very despondent after a terrible series of petty crime. Seems things are getting way worse:

    Car locked by remote :



    Vermin:



    Gone, 1min 38 sec flat:

    Locked by key you mean key turned in the door lock?

    Yeah, I don't understand. Locked by key...... what does jamming have to do with it then?

    Did you check the doors after pressing the remote? I always check when in a city.

    How do you check your doors when your vehicle has keyless entry? The doors will not lock unless you walk away....

    You're screwed.

    The criminals know that there is a window of opportunity in these cases and they know which vehicles are good targets.

    Yeah, that system where it automatically unlocks when you get close is a PITA, it is not suitable for South Africa. Once had that on a rental Renault in the UK.

    In this case you have to make sure that the lights flash appropriately, indicating that the car is locked. From 10m away.

    Mine is keyless, but you still have to press the button, and that suits me.

    Pull on the back door handle after locking. Shouldnt open if the car is properly locked.

    so walk away, and walk back, but don't the doors open again? or just the drivers door? (don't have keyless entry, how does it work?)

    Some of the keyless entry systems unlock if you just get close to the car, and lock when you leave. No button presses.

    These are very problematical if jammed, they only way to avoid that is if they use nonstandard frequencies, but I don't believe that they do.

    One needs to physically check that the car is locked and not just imagine/hope it is locked. Mine doesn't even have remote locking, and I still check it by pulling on the handle, because there are other tricks (like pulling a passenger door open a fraction while in another car or a pedestrian, which works on remote locking, and probably keyless systems, too).

    Keyless entry systems are not suitable for SA, in my opinion.

    My Triton has keyless entry but luckily you have to press the remote or button on door handle. And when it locks the mirrors fold in, so when they don't I know there's usually a door open somewhere.

    If a keyless system locks automatically when you walk away one would assume it is when the key goes out of range. Jamming therefore, in a case like this, should make it lock even sooner? Or what am I missing?

    How do you know someone hasn't opened a passenger door a fraction causing it to not successfully lock (I have seen the CCTV footage myself) when you have gone out of range. Can you pull on the handle to double check that? If not, then keyless entry is a problem.

    On my wifes HRV, you close the door and push the button on the handle, car locks. Push the button again and it folds the mirrors / closes windows too I think.
    It'll only unlock again if you put your hand behind the handle to pull it open. Pretty easy system. (obviously the key fob must be close to the car)

    There seems to be some confusion on how keyless entry works.

    This applies to Toyota vehicles.

    Keyless entry unlocks the car when you put your hand INSIDE the door handle to open it. Not on your way to the car. Keyless entry locks the car when you touch the door handle on the outside, if the key is in the car, it will continue to beep until you remove it, if a door is not closed properly, it will not lock and the long beep will be activated again. I feel I am better off with keyless entry than using a key remote to lock and unlock. I stand next to the vehicle when I lock and unlock, no chance of keyjamming here...

    No matter how we scratch our heads, the whole incident leaves you totally frustrated. You kind of build a little bubble where you think you are safe.

    I must mention that the SAPS were on the scene within 5 minutes. Business robbery unit. The detective was super professional. He made it very clear that they are not taking any nonsense this year.

    Hope the perps get the memo.

    A solution would be to get a rfid blocking pouch. Basically a Faraday cage for your key. Lock car with remote, visually confirm it locking, then place key in the pouch. The keys transmit continuously and the tsotsi know this. So there is a window of opportunity to open the doors as you walk away.
