Why choose the Covlor CR L51-S smart door lock
The Covlor CR L51-S is built around the fundamentals that make a smart lock worth owning: fast, reliable entry and serious security. Like every Covlor lock, it offers face and palm recognition, fingerprint, PIN, RFID card and app control, with a concealed mechanical key for emergencies, so every member of your household has a convenient way in. It works with the Tuya / Smart Life app for remote unlocking, temporary passwords and access logs.
Built to last: all-metal gear motor
Durability is engineered into the CR L51-S. It uses an all-metal gear motor rather than the plastic gears found in many locks — metal gears keep working smoothly for roughly twice as long, so the lock stays reliable for years of daily use. A multi-bolt body, anti-tamper hardware and anti-spoofing biometrics (3D face recognition with liveness detection) round out the security.
Designed for Indian homes
The Covlor CR L51-S supports a wide 40–120 mm door-thickness range to fit varied Indian doors, includes emergency USB-C power for power cuts, and uses sealed electronics with a capacitive sensor to cope with heat, humidity and dust. Biometric data is processed on the device rather than the cloud, protecting your privacy while keeping entry fast and dependable.
Price, warranty and support
Covlor flagship smart door locks start around ₹24,000 and come with a 2-year warranty, spare-part availability and reachable Indian support. Explore the full range on our smart door locks shop, or compare models in our best smart door lock in India guide.
Who the Covlor CR L51-S is for
The Covlor CR L51-S suits homeowners and renters who want modern, hands-free access without overpaying for an imported nameplate, joint families that need capacity for many users, and anyone who values on-device privacy and reachable Indian support. It is equally at home on an apartment door in a metro and an independent house in a smaller town, and works well for offices, clinics and hotels that need secure, manageable keyless entry. Whichever household it serves, the CR L51-S is engineered to open instantly for the people you trust and stay firmly shut for everyone else, day in and day out, for years.
