SentrySafe FPW082HSB

D0 No Radio — No radio at all. It cannot phone home.

The unplug test

There is nothing to unplug — this safe was never connected to anything. Punch the 5-digit code into the backlit keypad and the motor-driven bolts retract, exactly the same whether your internet, power grid, or SentrySafe itself is running. The lithium battery (rated 5+ years) runs the keypad and motor; if it dies, the physical override key opens the door. No app, no pairing, no account, ever.

Why this tier: A battery-powered digital keypad safe with a motor-driven bolt lock and a physical override key. The manufacturer's own product page states no WiFi, Bluetooth, or app functionality exists for this model, and a grantee search for 'SentrySafe' on fccid.io returns no matches for the safe manufacturer (the only 'Sentry' hits are an unrelated Bluetooth-audio company, 'Sentry Industries limited'). No intentional radiator is present, so D0 applies even though the lock itself is electronic.
