Door Materials & Mounting That Lasts

The lock is smart. The door just has to survive weather and torque.

1) Wood Doors

• Pre-drill and seal all holes with varnish or thin epoxy to stop moisture wicking.
• Use stainless hardware (#304 or #316) — no zinc plated stuff outside.
• Add nylon spacers if panel thickness > 2 in to avoid latch bind.

2) Steel Doors

• Apply rubber gasket between metal and lock plate to isolate galvanic coupling.
• Use anti-corrosion primer around cutouts; edge paint after drilling.
• Ensure electrical bonding if part of lightning network (see Post 5).

3) Fiberglass & Composite

• Requires backing block inside core — don't rely on foam alone.
• Drill slowly to avoid delamination; use step bit and tape surface.

4) Thermal Bridge Check

Keep metal lock interior side from direct contact with outside metal to avoid condensation. Tiny silicone washers work wonders.
