Waterproof Smart Locks for Exterior Doors: What to Demand

Black Sea rain, Aegean sea humidity, or just an open garden gate — a regular smart lock dies within months in these conditions: moisture corrodes the board, the screen fails, the fingerprint reader stops responding. If your door is exposed, demand this:
1. Real waterproofing
Immersion testing or at least IP65 — FANDAN's B60 is deep-immersion tested.
2. Anti-corrosion materials
304 stainless steel (F21W) or aerospace aluminum (F18); tempered glass over ABS plastic.
3. Protected electronics
Conformal-coated board and a sealed Type-C emergency port.
4. Redundant access
Wet fingers fail biometrics — require PIN + card + app + mechanical key backup.
