The HIDALIFE HL-669FL is a robust smart fingerprint door lock crafted from heavy-duty zinc alloy and engineered for over 250,000 use cycles, making it an ideal security solution for homes, rentals, and short-term rentals. It offers four convenient unlocking methods: ultra-fast fingerprint recognition in just 0.3 seconds with storage for up to 50 fingerprints, a backlit keypad that supports up to 20 user codes (4-8 digits) with an anti-peep feature that lets you enter random digits before and after your code to prevent prying eyes, one-time use passcodes for visitors or deliveries, and a hidden mechanical key for emergency access when batteries are fully drained. The lock provides versatile smart locking modes, including an auto-lock mode with a customizable delay time from 2 to 99 seconds (default 5 seconds) for hands-free security, a one-touch locking button for instant safety, and a passage mode that keeps the door unlocked for free movement during parties or when carrying items. Advanced security features include a vacation mode that disables all electronic access except the programming code and key, a silent mode for quiet nighttime entry, a tamper-proof lockout that activates after 5 incorrect password attempts, and a low-power alert that beeps 10 times to remind you to replace the 4 AA alkaline batteries (not included), which provide over 13 months of battery life. Designed for a universal fit, this lock works with standard doors 1-3/8" to 2" thick, with a 2-1/8" (54mm) door hole and a 2-3/8" or 2-3/4" backset, and comes with all necessary installation hardware, a drilling template, and access to step-by-step guide videos, requiring only a Phillips head screwdriver for a straightforward DIY installationthough a power drill is not recommended. With its combination of rapid access, flexible access control, intelligent security, and durable construction, the HL-669FL delivers the perfect balance of proactive security and everyday convenience for modern living.
