Scientists from Ruhr University Bochum (RUB) in Germany have revealed a major flaw in vehicle keyless entry systems by demonstrating a new device that can ‘learn and record’ radio codes used to lock and unlock car doors. In the same way that a universal remote control can mimic commands from your TV and DVD controller, the new device could enable thieves to access buildings and cars after remote eavesdropping from a distance of up to 100 meters.

The security system scientists cracked is based on KeeLoq RFID technology used in millions of cars around the world. Leading the research is RUB professor Christof Paar, who said “eavesdropping on as little as two messages enables illegitimate parties to duplicate your key and to open your garage or unlock your car.”

Does anyone else find it ironic and funny that this post is about security and how some people are duplicating keyless remote codes... but at the same time the google ad banner below is selling factory original keyless entry remotes on the cheap?

On a more serious note - I wrap foil around my keychain so the aliens and eavesdroppers can't read it's brain.

Too bad I had FF block all the ads lol but good call nonetheless

This might cause the general public to force automakers into finding another way to unlock their cars...

this theory has been floating around for awhile.

Well, this is why we have insurance. I sure don't want my car or its belongings stolen, but I am not going to deprive myself from a keyless entry system because of society.

So does this mean that not only you can unlock the car, but you can press the start button and drive away

I only use my remote in an open lot for that reason. Majority of the time I walk up to the car and just open it with the key.

Last year, Someone broke into my lincoln at the mall without setting the alarm off and leaving the drivers door wide open...I wonder if that could have been how it happened. :uh:

EDIT:

And what about rolling codes on Garage doors?? They couldnt duplicate those unless one opened the door with the master switch and had the door to program, or could they?
