Introduction
Few things are more stressful than standing at your front door with groceries in both hands, entering your code, and hearing nothing but rapid beeping. Understanding FEOCEY’s battery warning system helps you replace batteries proactively and never experience a lockout.
Battery Warning Timeline
100% – 50% Battery Level
Normal operation. No warnings or indicators. The lock functions normally and the app reports battery level accurately in this range.
50% – 20% Battery Level
App notification: When battery drops below 50%, the FEOCEY Home App will display a battery warning icon on the lock’s device card. This is the first and least urgent warning. Schedule battery replacement within the next 2-3 weeks.
20% – 10% Battery Level
LED indicator: When battery drops below 20%, the lock’s LED indicator flashes orange during unlock operations. This is a moderate warning – replace batteries within 1-2 weeks. The app sends a second push notification at this threshold.
10% – 5% Battery Level
Audio alert: When battery drops below 10%, the lock emits 3 rapid beeps during each unlock. The LED indicator continues to flash orange. Replace batteries within 3-5 days. The app sends a high-priority notification at this level.
Below 5% Battery Level
Critical warning: At below 5%, the lock enters power-saving mode. Wi-Fi connectivity is disabled to conserve remaining power. The keypad still functions, but remote unlock and app connectivity are suspended. Replace batteries within 24-48 hours.
What Happens When Battery Dies Completely
If the battery fails before you replace it, the lock’s response priority is:
- The physical key always works – this is the ultimate backup and requires no battery
- The keypad will not respond to code entry when battery is fully depleted
- The app cannot connect to the lock when battery is dead
How to Replace Batteries
FEOCEY X GEN1 uses 3x CR123A lithium batteries. To replace:
- Open the interior lock body cover (slides upward)
- Remove the old batteries, noting the correct polarity orientation
- Insert 3 new CR123A batteries with correct polarity (+ and – correctly oriented)
- Replace the cover
- Wait 10 seconds for the lock to restart and reconnect to Wi-Fi
Proactive Maintenance Tips
The single most effective way to prevent lockouts is to replace batteries on a schedule, not reactively. We recommend replacing all batteries twice per year regardless of current level – spring and fall are convenient markers. This eliminates the risk of unexpected battery failure.
