Introduction
There is nothing worse than getting locked out because of a dead battery at an inconvenient moment. FEOCEY smart locks are designed to warn you well in advance.
Understanding FEOCEY Battery Notifications
Notification Levels
- Level 1 (25% remaining): First notification in the app. Provides approximately 3 months of warning.
- Level 2 (10% remaining): Second notification. Lock indicator flashes yellow during operation.
- Level 3 (5% remaining): Final warning. Indicator flashes red. Approximately 2-3 weeks remain – replace immediately.
Indicator Light Patterns
- Green (steady): Lock is powered and healthy
- Yellow (flashing): Battery below 25%
- Red (flashing): Battery below 10%
- Red (rapid flash): Battery below 5%
What Happens When Batteries Die
When battery voltage drops below the operational threshold, the lock will no longer respond to app commands or keypad inputs. The physical key backup continues to function – the key mechanism is purely mechanical.
Emergency Access Options
If locked outside: Use your physical key. If you do not have your key, call a family member or trusted neighbor with a spare. As a last resort, contact a FEOCEY-authorized locksmith.
If inside: Manually turn the thumb turn to lock/unlock, then replace batteries as soon as possible.
