DESLOC K140 Plus is a premium keyless smart deadbolt designed for secure and convenient front door access. Palm vein recognition allows fast, touch-free unlocking using a biometric pattern that is difficult to copy, while local biometric storage helps keep personal access data under user control. Built-in Wi-Fi lets users manage the lock remotely without a separate hub, including app control, voice control, remote access requests, user management and activity visibility. The K140 Plus supports multiple ways to unlock, including palm vein recognition, PIN code, mobile app and mechanical key backup. The included door sensor enables real-time door status and auto-lock when the door is closed, helping reduce the chance of leaving the door unsecured. A 10,000mAh rechargeable lithium battery provides up to 9 months of use, with low-battery alerts and a Type-C emergency power port for backup power when needed. The Black finish offers a clean, modern look for residential entry doors. | Desloc | | K140 Plus Smart Lock with 10,000mAh Battery Wi-Fi Replacement Deadbolt with Palm Vein Recognition and Auto Lock | Black | Best Buy
