How many times is taking mfcuk to find a key

I would like to copy a VIGIK RFID badge. It’s MIFARE type badge. I’ve an ARC122 USB reader / writer and my OS is Linux like. I compiled mfoc and mfcuk successfully. First I tried to copy the badge with mfoc using this command:

mfoc  -P 500 -O Matrice.dmp 

And I’ve got this error :

    Found Mifare Classic 1k tag ISO/IEC 14443A (106 kbps) target:     ATQA (SENS_RES): 00  04   * UID size: single * bit frame anticollision supported        UID (NFCID1): 63  0e  43  bc         SAK (SEL_RES): 08   * Not compliant with ISO/IEC 14443-4 * Not compliant with ISO/IEC 18092 .../... mfoc: ERROR:  No sector encrypted with the default key has been found, exiting.. 

After a search on the web, I found I’ve to use mfcuk tool like this for find a key :

mfcuk -C -O Matrice.dmp -R 0:A -s 250 -S 250 -v 3 

But it’s taking hour without result. How to do that quicker ?
