Cloning RFID Fob

**hawkburn** · August 26th, 2009, 06:32 PM

Hello guys. I haven't posted here in a while, but I have a technical question, and assume someone might be able to give insight.

I wanted to clone an RFID fob that gives access to an apartment building (my girlfriends) but don't want to pay around $75. The fob looks exactly like the HID ProxKey II seen here:

I've seen you can order them unprogrammed for as little at $4, but where could I get one cloned, or is that even possible really?

Thanks for your help guys.

Unless it is encrypted, or so long as the encryption is minimal you should be able to use a reader/writer to clone the chip. Now the issue here is that readers and writers are more expensive than the key you are wanting to produce, so I see no reason to buy your own. You would also need to be certain that it is the same specifications as the original, and to be honest you could have many different chip designed built into a standard casing.

Now whether or not a service exists that will do it for you is beyond me.

You might have some luck looking at chinese retailers, but the quality and success you will get with these products is uncertain and they cost almost as much as a key.

If my research is correct, this reader is at least for the same frequency.

Well it does not appear to have any encryption on the device, so it may be very easy to duplicate. I'm also fairly certain its 125Hz system. So if you want to duplicate the key that is where you should start, but to be honest it will probably cost you around, or as much as getting the 75$ key.

Also that reader/writer I posted doesn't seem to be HID compatible. The companies programmer cost 715$, so I say good luck with your hunt.

Hi guy after years of research the RFID SLOT team find a way to copy or rewrite all original HID 125Mhz by using a Brute-force and good dictionary under LINUX for who are interest about i can give you the DICO

I'm interested. Could you send me a private message? Thanks.
