Buying your first smart lock can feel overwhelming — face recognition, Wi-Fi, mortise sizes, apps. This smart door lock buying guide from Covlor® breaks the decision into seven simple steps, so you choose the right lock for your door, your budget, and your security needs the first time.
Step 1: Measure Your Door
Before anything else, check your door. Note the thickness, whether it opens left or right, the material (wooden, metal, or uPVC), and the existing lock cutout or mortise size (commonly 6068 in India). Most Covlor® locks fit standard doors, but confirming the fit avoids surprises.
Step 2: Choose Your Unlock Methods
Decide how you want to get in. Options include fingerprint, face recognition, PIN code, RFID card, smartphone app, and a mechanical key backup. More methods mean more flexibility for family, guests, and staff. If you are unsure between biometrics, compare fingerprint vs face recognition.
Step 3: Wi-Fi or Bluetooth?
Choose Wi-Fi if you want remote lock/unlock and instant alerts from anywhere. Bluetooth-only locks are fine if you only need control near the door. For most homes and offices, Wi-Fi (often via the Tuya or TTLock app) is worth it.
Step 4: Check the Security Features
A good lock protects, not just opens. Look for encrypted access, tamper and forced-entry alarms, anti-peep passwords, and lockout after failed attempts. Our guide to the best smart door lock for home security covers these in detail.
Step 5: Battery Life & Backup
Smart locks run on rechargeable or AA batteries lasting several months, with low-battery alerts. Make sure yours includes a mechanical key and an emergency USB power port so you are never locked out.
Step 6: Warranty & Installation
Every Covlor® Smart AI Door Lock comes with a 2-year warranty covering manufacturing defects, plus free professional installation on orders of two or more locks in Bihar (within 7–10 days of delivery). Reliable after-sales support matters as much as the hardware.
Step 7: Match Budget to Value
Set a budget, then pick the lock that covers your must-have features. You do not always need the most expensive model — you need the right features for your door and lifestyle. Review the benefits of smart door locks to prioritise.
