Design and build quality
Premium stainless steel construction
One of the first things you notice about the modern keypad mortise lock with cylinder deadbolt is its solid construction.

Keypad entry system and access control
Efficient keypad functionality
The keypad entry system simplifies access by eliminating the need for physical keys. Users can enter a secure code to unlock the door, making it ideal for shared spaces or environments where multiple individuals require access.
Non-volatile memory advantage
A key feature of this electronic keypad door lock with non-volatile memory is its ability to retain programmed settings even during power loss. This ensures uninterrupted operation and maintains access credentials without requiring reconfiguration.
Advanced locking mechanism
Cylinder deadbolt for enhanced security
The inclusion of a cylinder lock adds an extra layer of protection. This dual-security system combines electronic access with traditional mechanical reinforcement, making unauthorized entry significantly more difficult.
Deadlocking latch system
The auxiliary deadlatch mechanism prevents forced entry techniques such as “credit card slipping.” Once engaged, the latch secures firmly, providing reliable resistance against tampering.
Operational functionality and user experience
Mechanical knob and lever operation
In addition to digital access, the lock features a mechanical knob and lever system. This ensures smooth operation from both sides of the door and provides a fallback method in case of electronic issues.
Passage mode flexibility
The lock can be switched to passage mode, allowing free movement without requiring a code. This is particularly useful in high-traffic areas such as offices or restrooms.
Remote control capability
The ability to control the lock remotely adds convenience and flexibility. This feature allows administrators or homeowners to manage access without being physically present at the door.
