Hi - my new dorm is locked up with Medeco Sitekeys. It is incredibly irritating - because my key only opens up some doors - leaving me a really really slow route that I have to take to get to my room. So - I'd like to try to make a copy of someone else's sitekey. Oh - and the managers of the building won't help me out with this :( Anyways - my sitekey has two contacts on it - both of which I believe are isolated from the actual key. I pulled off the cover of the key - and there is some little round cylinder thing in it - which only has two contacts on it (it looks like an oversized watch battery) My first impulse was that it was probably just a diode - so I tried flippign it upside down (one contact on top the other's on the bottom) and that didn't work at all. So - my multimeter is being sent to me from back home and should arrive soon - so I'll be able to do further tests with it then - but in the meantime - does anyone know how these work? BTW - there is some writing on the battery like thing. This is what I could make out:1993 Dallas 0033 registered 03 C6 91 5E70000C23D7 (various small numbers that I can't make out)
Anyways - anyone have any advice? Thanks!
