Waterproof Smart Locks for Outdoors & Humid Climates: What to Demand

In the tropics, on the coast, or just under the rain, a regular smart lock dies within months. If your door is exposed, demand this:

1. Real waterproofing

Proof of immersion or at least IP65 — FANDAN's B60 series is deep-immersion tested.

2. Anti-corrosion materials

304 stainless steel (F21W) or aerospace aluminum (F18); tempered glass panel over ABS plastic.

3. Protected electronics

Conformal-coated board and a sealed Type-C emergency port.

4. Redundant access

Wet fingers fail fingerprint readers — require PIN + card + app + mechanical key backup.

FANDAN outdoor models

• B60 waterproof rim — gates and exterior doors
• F21W stainless — coastal climates
