HARFO Smart Door Lock, Heavy Duty 5 in 1 Keyless Entry Door Lock
This smart door lock is ideal for busy homeowners who want to control access without fumbling for keys. The 5-in-1 design offers fingerprint, passcode, IC card, app, and physical key entry, so you can let in the dog walker or a repairman even when you're at work.
Installation takes about 10 minutes with just a screwdriver—no drilling needed. The reversible handle works for both left- and right-handed doors. Pair it with the optional Wi-Fi gateway (sold separately) to lock or unlock from anywhere, check access logs, and set temporary codes for guests.
