The biggest mistake people make buying a smart lock in India is ordering before checking whether it fits their door. The right lock depends on your door type, the unlock methods you want, and a few practical details. This guide gives you a clear way to choose — and a checklist to confirm before you buy. For a ranked list of options first, see our best smart locks in India 2026 roundup.
Step 1: Match the Lock to Your Door
- Standard wooden / mortise doors (most Indian flats): a full digital mortise lock with fingerprint, PIN, RFID, and key is the usual choice.
- Existing handle you want to keep simple: a smart handle lock gives keyless entry with a familiar lever design.
- Cylindrical/knob-style doors: choose a lock specifically rated for cylindrical fitment.
- Door thickness & handing: measure thickness and note whether the door is left- or right-opening — most locks support a range, but confirm it.
Step 2: Pick Your Unlock Methods
Modern locks offer several ways in — more options means more convenience and a reliable fallback:
- Fingerprint — fastest for daily use.
- Passcode (PIN) — great for guests; set temporary codes.
- RFID card — handy for kids and elderly family members.
- App / Bluetooth / Wi-Fi — unlock remotely and get entry alerts.
- Physical key — the essential emergency backup.
Step 3: Bluetooth or Wi-Fi?
Bluetooth locks work over your phone when you're nearby and are very battery-efficient. Wi-Fi locks add true remote access — unlock for a visitor while you're at work, or check logs from anywhere. Choose Wi-Fi if remote control matters; Bluetooth if you mainly want keyless entry at the door.
Step 4: Check Battery & Backup
Most smart locks run for 6–12 months on AA batteries and warn you before they're flat. Confirm there's an emergency power option (USB-C jump or mechanical key) so a dead battery never locks you out. We bust the common worries in 10 smart lock myths in India.
