FAQ of using 125kHz T5577 RFID Key Cards
Question 1: Can I directly register these key cards to my electronic lock?
Answer: No. These RFID key tags are blank cards without pre-programmed card numbers. The electronic locks cannot write or program a blank key card. The electronic locks can read only. They read the card numbers from the programmed key fob and then verify it pass or not.


Question 2: Why I can't copy my old tags/cards to your cards by a card writer?
Answer: First, make sure that your card is the same RFID frequency of 125kHz. Not all RFID cards are 125kHz type. For example, the frequency of some popular key cards are 13.56MHz, which is also called NFC card or IC card. Cards of different frequencies are incompatible.
Second, make sure that your RFID card writer can work for the frequency 125kHz, and that you set it in the right channel. Some RFID card writers have several working frequencies.
