MIFARE CLASSIC 1k UID clone not working

Hi All

I am new to the proxmark, but have managed to make a couple of (what seem to be) perfect clones for my apartment building.
I seemed to have no issues collecting the keys (using an extended dictionary) and I used both the restore and the cload methods to "clone" the card but neither method seem to work.
I also tried the same thing on a CUID card but for some reason our elevator doesn't seem to accept it.
I have read all of the manuals and searched the forums but I am stuck!

Any ideas?

>> Original Card

UID : f2 83 0d XX
ATQA : 00 04
SAK : 08 [2]
TYPE : NXP MIFARE CLASSIC 1k | Plus 2k SL1
proprietary non iso14443-4 card found, RATS not supported
No chinese magic backdoor command detected
Prng detection: HARDENED (hardnested)
