Keyless Entry Door Lock with Stainless Steel Housing and IP66 Waterproof Rating FM309

Secure your home with the FM309, a keyless smart lock that eliminates the need for traditional keys. This keyless lock is designed to fit multiple mortise types including 60/70, 5050, 5072, 5572, 6072, 4585, 6085 and 7054, making it a versatile digital door lock for various door preparations.

The FM309 offers five ways to unlock. Use your smartphone via the TTLock app, touch the fingerprint sensor for instant access, enter a password on the keypad, tap an RFID card, or use the mechanical backup key for emergencies. As a smart house lock, it provides convenient keyless entry for the whole family while maintaining high security standards.

This smart home lock supports up to 100 fingerprints, 250 passwords and 1000 RFID cards, making it ideal for families, vacation rentals, and small offices. Through the TTLock app, you can lock or unlock remotely when paired with a gateway, share eKeys with family members or guests, and view the complete audit trail of who accessed your door and when. The lock works with Google Home in the United States, Australia, and New Zealand.

The FM309 is built for long lasting performance. The stainless steel housing with glass screen and baking paint finish operates reliably in temperatures from -20°C to 70°C. It is tested to 100,000 unlock cycles and 98 hours of salt spray protection, with an IP54 waterproof rating. The lock fits door thickness from 30mm to 55mm.

Power comes from 4 AA alkaline batteries, lasting up to one year with typical use of 10 unlocks per day. A low battery alert warns you before power runs out, and the Type-C port accepts emergency power from any power bank.

Security features include incorrect attempt alert and lockout to prevent brute force attacks, anti peep scramble code that lets you enter random digits before and after your real password so no one can see what you typed, a tamper alarm that triggers when someone tries to pry the lock open, and a privacy switch that locks out all access except the administrator and override key. Passage mode allows you to keep the door unlocked during business hours, and double verification mode requires two methods to unlock for added security.

Whether you need smart locks for home, a keyless lock for your apartment, or a digital door lock for a rental property, the FM309 delivers the versatility, security, and smart features that modern homeowners demand. Its compatibility with multiple mortise types makes it one of the most adaptable keyless entry solutions available.
