The Matte Black DS10 Mini Alloy Smart Keypad Deadbolt Lock is a compact, keypad-operated deadbolt designed for front door security and convenient code access. Ideal for homeowners and small rental hosts, it supports up to 300 stored user codes and offers temporary single-use codes for guest entry without sharing a permanent passcode. This lock combines practical features—an adjustable automatic lock (5/10/20/30/60 seconds) that can be disabled—with low power consumption. It runs on 4xAA batteries, which can power the lock for about one year or roughly 5,000 operations; a power indicator light shows remaining battery status. The DS10's alloy construction and IP54 weather resistance help protect the mechanism outdoors, while anti-peeping code protection and a solid lock cylinder enhance durability. Installation is straightforward for standard residential doors: the DS10 fits 2-1/8" (54mm) door holes but is not compatible with 38mm holes. Customer support includes a 30-day customer commitment, a 1-year product warranty, and ongoing after-sales service.
