The Avent Security B3 is a next-generation smart door lock designed for homes, offices, and hotels that want both convenience and top-level security. With five different access methods – fingerprint, password, card, mechanical key, and app – you’ll never have to worry about being locked out again. Whether it’s the fingerprint door lock for quick keyless entry, a secure password, or even your phone through Bluetooth or Wi-Fi, the Avent B3 adapts to your lifestyle. It’s built to fit wooden, metal, and even glass doors with a thickness of 40–50mm, making it one of the best smart locks for front doors and a reliable choice for Airbnb and hotel room entry.
Powered by 4-AA batteries, the Avent B3 lasts up to 4,000 cycles, and if power runs out, you can easily recharge it using a USB Type-C port. This app-controlled lock supports up to 450 users – including 100 fingerprints, 200 RFID cards, and 150 passwords – making it ideal not only for households but also for businesses that need reliable access control smart locks. With Bluetooth and Wi-Fi connectivity, you can manage entry from anywhere, check activity logs, and share one-time access codes with guests, making it perfect for airbnb smart locks, offices, or hotels that want to simplify keyless room entry.
Beyond convenience, the Avent Security B3 is built with durable aluminum and comes in stylish black or stainless steel finishes that complement any modern door. It combines the strength of a biometric office door lock with the ease of a wifi smart lock, giving you peace of mind whether you’re at home or away. From a digital door lock for your Nairobi apartment to a hotel smart lock system that supports seamless guest check-ins, the Avent B3 proves to be more than just a lock – it’s a complete electronic access control system designed for today’s lifestyle.
