The SmartKeeper Basic USB Cable Lock Mechanism (LK03PK) is a color-coded security system that protects USB Type-A cables/devices (keyboards, mice, USB flash drives) in USB-A ports, preventing unauthorized removal, accidental disconnection, and access by internal users. The lock is pink (PK version) and is designed to withstand tampering; it can only be removed with the corresponding SmartKeeper Essential Lock Key Basic (U03), which is not included. Installation is tool-free — simple plug-in and lock operation. It is suitable for computers, laptops, servers, network equipment, medical devices, public kiosks, exhibitions, and industrial control equipment. No software required; it is a standalone physical security device. Model: LK03 (LK03PK = pink). EAN/Barcode: 8809534692536.
