Take full control of your keys with the free TTLock App—generate anti-peep virtual passwords (6–9 digits) and share time-limited access permissions with family, tenants, or cleaners. Engineered for resilience, the zinc alloy body with IP65 certification resists water, dust, and extreme temperatures (–20°C to 55°C). Its dedicated wall-mount design ensures secure installation both indoors and outdoors, standing strong against rain, snow, and harsh environments. Powered by 3 x AAA batteries (not included), the lock box sends real-time low-battery alerts via the app. If power runs out, use a USB-C power bank for instant charging to regain immediate access—no more lockouts due to dead batteries. The reinforced zinc alloy cover resists tampering and impacts, while the spacious interior securely holds up to 5 keys, 3 access cards, and 1 car key fob. Its dustproof and anti-pry design helps keep valuables safe in any setting. Designed for homeowners, property managers, and real estate professionals, the app lets you create temporary access codes with customizable start and end times. Streamline short-term rentals and property management with reliable, keyless access.
