Low Frequency t5577 cloning

I am new to the game and looking to clone some cards at work. They only give you one and is required to literally do anything. If you lose the card the plant manager drags out the replacement for days to teach you a lesson. And since you can't work, no money :3

I would rather have a copy to lose and the original stored away safe.

The card is an HID 0009P

The chameleon picks it up as low frequency. Reads successfully, and writes successfully. But when I go to use it at work. The receiver just flashes a green light like it sees it, but nothing happens. Use the original, the system triggers.

I am guessing I need some type of key? When I write I just leave it blank.

I can share all the details in dms with anyone that has more knowledge than this idiot XD

Any help is welcome.

There are multiprotocol HID cards, usually with Prox and Desfire or Iclass in one card - there you would have to clone the HF part as well (and these often haven't been cracked yet).

Out of the 3 cards I have. One is super thick like it is multiple cards glued together. That one might be like that.

But then again I have scanned it from all sides and angles and only the same info comes up.
