lots of info concerning this at . .
and the Medeco crack . .
. . from what I read they just had a data sheet on the keys, not a physical one . . considering their knowledge they probably had an idea what the key looked like . .
That's why when my house is in a state of "Armed - Away" I lock the doors with an electronic locking plate that gets magnetically pulled out of the door into the frame. Bump or not, the door isn't going to open without breaking the WHOLE doorjam (it's re-inforced with a plate across the WHOLE doorjam).
Oh, battery backed of course, with a quick release button incase someone needs to exit the house in a HURRY (fire, etc.)
Or at least it will when the stuff come in from the mail.
Can you give me an example/link of what you're using? This sounds smarter then buying a crazy mechanical lock. Thank you.
P.S. my Bumpkeys are on the way.
