I had the following message in an e-mail yesterday regarding the cloning of car Key fobs.

Just to make everyone aware of a motor scam that you may or may not have heard about :-
 
If vehicle keys with fob are left within a certain range of a vehicle parked up ( eg near your front door/hallway ) , there is a device which thieves are using to pick up the signal to the fob &  unlock the vehicle rather than having to break into the vehicle in their usual manner .
 
The best policy is obviously not to leave anything of value in a vehicle should the fob get cloned & to store the keys as far from the vehicle as possible in a metal container to try & block the cloning device .
 
Please could any of the  Site Managers who receive this email pass the message on to the guys who have site vehicles .
 
Thanks ,

Now I thought the fobs had to be in use to transmit a signal so they could only attempt to clone while you were locking or unlocking your car.

Cars like my 370z have keyless entry where you only need to be in close proximity to unlock the car without actually using the fob so my question is are they transmitting all the time?

Does anyone on here know the facts behind all this?

I wonder how the car knows how far away the fob is? Guessing that it is simple signal strength

Presumably if someone could stand between your car and your fob with some kind of signal booster they might be able to trick it into unlocking

You are correct.  , the Fobs just transmit, the recivers in the car just recieve, theres no active hand shaking going on between the two.

There are some aftermarket systems that have a Intelligent 'Pager' alert on the Fob, which talks between the Fob and Car but not your average run of the mill systems.

With the Nissan system you have to be in very close proximity of the lock otherwise you cant open the door, and thats without pressing any buttons on the fob, similar to the cards used by Renault it works on proximity. Pressing the buttons on the fob then it works just like every other fob.

All the works vehicles just have normal fobs, and in any case there`s nothing special about a Shitroen Nemo worth stealing so I`m not too worried about that

Potentially possible with keyless entry systems, where the fob has a transponder in for the remote locking.

But virtually all remote locking systems have been broken now, so no real point in getting overly concerned.  Very few of us have the most desirable/profitable car in the neighbourhood....   ....so hopefully wont get targeted.

Depends on your neighbourhood...

Apart from the coffin dodgers at the end with their W plate Astra-G, I'm the only car owner who's registration starts with a single letter.

Come to that, from what I can see, there are 2 rusty cars in my road. Both mine.

Oh dear. Do I have to put my tin hat on again?
