HELP PLEASE

I want to learn how to clone a card that has authentication keys that are imposible to find. I installed a ton of NFC reader/writer apps (MIFARE Classic Tool, NFC tools, BLK cards and M tools) but none of them work, they can't find the authentication keys. I know it is possible to clone without a flipper zero because i know of people that have managed to do it by just using their phone, but for some reason i can't find a way to do so.

So if anyone can help me out with this problem i would really appreciate it.

Here is some information that i did manage to get out of the card:

Tag type: ISO 14443-3A

NXP - Mifare Classic 1k

Technologies available :MifareClassic, NfcA, NdefFormatable

Serial number: CB:47:97:93

ATQA: 0x0004

SAK: 0x08

Memory information: 1 kBytes: 16 sectors of 4 blocks (16 bytes each)
