Using Generic MIFARE Cards with Lockly Smart Locks
Lockly RFID locks use standard MIFARE Classic 1K cards (13.56 MHz), but ship with one sector key changed from the factory default. This causes generic cards to fail enrollment.

Important clarification: This process does not clone an existing card or bypass your lock.
