✅ Yes, a blinking light on the remote control of your Secureye S-FGD200 biometric glass door lock often indicates a low battery. To confirm if it's a cell (battery) issue:

Stand close to the lock and press the remote. If the lock doesn’t respond and the remote still blinks, it’s likely the cell/battery in the remote is weak or drained.

Replace the existing coin cell (usually a CR2032) with a fresh one and test again.

If the problem persists after battery replacement, try re-pairing the remote or contact Secureye service support.

📦 This issue is common across India due to temperature changes or battery shelf life during storage. Always use high-quality batteries for best performance.

❓ Do I need to change the cell in the biometric device itself?
🛠️ The Secureye S-FGD200 lock runs on internal batteries (usually AA or AAA) for biometric operations. If:

The biometric scanner or keypad is unresponsive, or

There’s no sound/beep when using the fingerprint/card/password,

Then it's time to replace the internal main power cells (consult the manual for cell type). However, if only the remote isn't working while the lock works fine with fingerprint or code, you only need to change the remote's battery.
