Before buying, check:

• Is your door deadbolt-ready?

🔍 Key Features to Look For

1. Unlocking Methods

Modern smart locks offer multiple ways to open the door:

• ✅ Fingerprint recognition (fast & secure)
• ✅ PIN code entry (great for guests)
• ✅ Smartphone app (control from anywhere)
• ✅ RFID cards or NFC (ideal for office doors)
• ✅ Traditional key backup (for emergencies)

💡 Pro Tip: Choose a lock with at least two unlocking methods.

2. Connectivity

Keywords: Wi-Fi smart lock, Bluetooth smart lock, Zigbee, Matter

Make sure your smart lock connects properly:

• Wi-Fi: Control from anywhere, receive real-time alerts

3. Auto-Lock and Unlock

Set your door to:

• Auto-lock after a set time

This adds convenience and peace of mind.

4. Battery Life

Most smart locks run on AA batteries or rechargeable lithium cells. Look for:

• Low-battery notifications
• Emergency USB power port
• Battery life of 6–12 months minimum

💡 Some models on niceshine.com last up to 18 months per charge.
