Having trouble emulating a nfc classic 1k key with all sectors unlocked on Salto reader. Does anyone know anything about these?

Hello, I have tested a few different types of nfc tags and locks that I have around but an nfc classic 1k key has simply not been working. All the keys have been found and all the sectors have been read. I've tried to look into detailed specs of the reader but it seems like they don't offer much, even on their datasheets. One theory I tried to dig into was if the reader works on 13.50 MHz instead of the usual 13.56 MHz as it is known to cause issues, but I've come up short for answers. Does anyone know a potential solution to my problem?
