Introduction
Smart lock troubleshooting guide for 2026. Common issues and solutions for installation, connectivity, battery, and performance problems.
Installation Issues
Lock Doesn’t Align
Adjust mounting plate position. FEOCEY includes adjustable shaft for perfect alignment with existing deadbolt.
Screws Won’t Tighten
Ensure mounting plate sits flush against door. Don’t overtighten — snug is sufficient.
Connectivity Problems
Wi-Fi Connection Fails
Ensure 2.4GHz network (not 5GHz). Move lock closer to router during setup. Check Wi-Fi password doesn’t contain special characters.
App Can’t Find Lock
Put lock in pairing mode (press button). Ensure Bluetooth enabled on phone. Restart app and phone if needed.
Battery Issues
Battery Drains Quickly
Check alignment — misalignment causes motor strain. Reduce excessive auto-lock cycles. Use quality lithium batteries.
No Low-Battery Alerts
Ensure app notifications enabled. Check battery contacts clean. Replace with fresh batteries.
Performance Problems
Slow Lock/Unlock
Weak batteries cause slow motor operation. Replace batteries immediately if operation slows.
Unusual Noises
Grinding or straining indicates misalignment. Adjust lock position. Lubricate deadbolt mechanism if needed.
Auto-Lock Not Working
Check auto-lock settings in app. Ensure door closes fully. FEOCEY’s gyroscope needs door to be properly closed.
Software Issues
App Crashes or Freezes
Update app to latest version. Clear app cache. Reinstall app if problems persist.
Firmware Update Failed
Ensure strong Wi-Fi connection during update. Don’t interrupt power. Contact support if update fails repeatedly.
Emergency Procedures
Locked Out with Dead Batteries
Use backup physical key. FEOCEY includes key that works with original deadbolt cylinder.
Forgotten Master Code
Factory reset lock (see manual). You’ll need to re-pair with app afterward.
Physical Damage to Lock
Contact manufacturer support. FEOCEY offers warranty coverage for defects.
Preventive Maintenance
- Clean lock with dry cloth monthly

When to Contact Support
Contact FEOCEY support if:
- Lock completely unresponsive after battery replacement
