Hi!

i Have an X1 magic gen1 in my hand, but it will not work with this card

do i need something that can handle 7 byte uid?

The data in the screenshot shows a 4 byte NUID? Why do you think you need 7 byte UID support?

What exactly is the issue? From what I see, the problem is not the target chip but the cracking and decoding of keys from your source card?

At first, when my implant was coded with some other imormation. I tried if the card reader will recognize my magic gen 1 implant. And yes it did ”no access”

but when i have cloned this tag, the card reader do not recognize it at all… :face_with_monocle:

Card reader is an RCO 509

So what you saying is that my gen 1 chip will work as an clone for that dump i posted?

I think the “failure” is happening in a different part of the transponder check in the lock itself. When the gen1 chip was programmed as some other transponder ID, the lock failed at the “UID check” phase and indicates “no access”, but when you tried to clone the working fob the lock reads the UID and says “ok the UID is correct” then proceeds to try to check further details, maybe use keys to authenticate a sector.. and this is where it is failing.. and this failure state is very uncommon / unlikely, so it is probably silently failing.

I don’t know if you can clone the source fob to your gen1 chip or not. You would have to try to break the keys and clone not only the UID but also the sector contents and keys for each sector, and from the screenshot you posted, it says the PRNG (pseudo-random-number-generator) is “hard” which means it is not easily predictable and thus not easy to crack the keys on your source fob.

It may be possible to accomplish this, but it would take more expertise and patience. You might possibly have to sniff some interactions between the lock and the real source keyfob first to see if you can derive keys from that data. There are other methods of attack but it will require more training and guidance than I can offer.

Have you simply tried to just enroll your xMagic?
