The Yale SYDM3109 Series Digital Door Lock combines advanced security with everyday convenience. Unlock your door using PIN codes, RFID key tags, or a traditional key, and enjoy extra security with the scramble code feature to mask your PIN.
Key Features:
- Multiple Access Options: Unlock with PIN, RFID tag, or physical key for ultimate flexibility.
- Enhanced Security: The scramble code feature and child-safe handle button provide added protection.
