Depends on how cheaply the unit was designed. I remember putting in back to back diodes on the front gates to protect against stuff like static discharge. If this was done, you would have to generate a HELL of a lot of EMF to blow these out. Time to bring out the van-de-graf generator :-). But in this era of cheaper cheaper cheaper, I bet these aren't there anymore. What will probably happen is you'll DOS the box. The AGC on the front end will try to cut the signal back as far as it can, probably not enough, the decoders won't see a clear signal/sequence, so will probably fail to engage. But I wouldn't be surprised if you burned out a front end.
<<much snipping>>
I'm incluned to agree that a low end unit will probably scatter parts if you hit it with enough power. Which, I suspect, would lead it to "fail closed", with the gate/door/what have you still locked. As has been mentioned, simply jamming the thing would be a piece of cake. In the context of a pen-test, you could probably combine a Remote Door DOS with a bit of social engineering to gain entrance to a prem, if it was within the scope of your test. Cheers, L4J
