About this item

• [Two‑Way Security & Access Control] This double‑sided door knob features independent keypads and identical cylinders on both sides, with the same mechanical keys working for both cylinders – supporting up to 50 user codes per keypad. The backlit keypad ensures easy operation in any lighting. Designed for gates, fences, and doors that require controlled entry from both directions – indoors or outdoors, with dual‑side code management for enhanced flexibility.
• [Flexible Locking Modes] Choose between automatic or manual locking, and bi‑directional or uni‑directional control. Set the auto‑lock delay from 2 seconds up to 12 hours after closing, or disable it entirely during busy periods. This programmable electronic lock adapts seamlessly to homes, commercial offices, medical facilities, and departmental spaces – offering on‑the‑fly mode switching to suit any traffic flow.
• [Smart Synchronization & Power Efficiency] With the synchronization switch turned on, any code change made on one side is instantly mirrored on the other – saving time and eliminating duplicate effort. Anti‑peeping user code protection (virtual PIN shielding) and a low‑battery beep alert are built‑in. Ultra‑low power consumption allows 4 new AAA batteries (Batteries not included) to last over one year, and a Type‑C USB emergency charging port provides backup power for extra peace of mind – ensuring you’re never locked out.
