Re: Old trick that
so i you wang out static over the frequency it will stop the fobs talking to the cars..
A $50 hand-held 70cm radio, which you're legally allowed to use if you have an appropriate license, is all that is necessary to jam these key fobs. 433.920MHz is a common centre frequency for this stuff.
I learned this through first-hand experience (with a more expensive radio). Even though I was transmitting on 433.525MHz (to access Mt. Coot-tha repeater VK4RBC), the 5W signal was enough to de-sense the receiver in the car.
