How to Use & Install
Remove your existing Euro profile cylinder. Insert the SECBN51 and secure with its fixing hardware. Adjust the cam or included extension to suit your door’s thickness. Register fingerprints and RFID cards via the OLED interface or app and set Bluetooth pairing. If battery runs out, connect a power bank via USB for emergency unlocking.
Why Choose SECBN51?
The SECBN51 offers a robust balance of biometric security, flexible access modes, and retrofit convenience. Its adjustable length and protective features make it ideal for residential or interior use where a smart cylinder is needed but full smart-lock replacement is impractical. The inclusion of OLED feedback, electrostatic protection, and extended durability specs makes it a solid pick for modern door access control.
