6 in 1 CUID fob

They do these in different versions, I got the 3 x T5577 + 3 x UID

UID is basically Chinese speak for a Mifare Classic 1k gen1a

So you can write to it with a Proxmark3, Flipper Zero, iCopy etc.

If it was a CUID rather than UID, you could use MCT

What tools do you have available to you?

If you have the ability to enroll rather than copy, you could just enroll it into the system you have acces to…
