Security Features

Your data is safe with this lock. It uses AES-128 encryption. That scrambles your app data. Your fingerprint data never goes to the cloud. It stays on the lock only. PIN codes are stored with their own keys.

After 10 wrong PIN tries, the lock shuts down for 30 minutes. That stops guessing attacks. The fingerprint scanner gets smarter over time. It learns your finger better with each scan.

Every unlock is logged. You can see who got in. You can see when and how. The log goes back up to a year. That's useful for rentals and shared spaces.

Backup options if power fails:

• Use the key - it always works
• Use the USB-C port to jump-start the lock
• The lock works even without Wi-Fi

Smart Home Setup Ideas

The C220 works well with other smart devices. You can set up routines. When you unlock the door, the lights can turn on. The thermostat can adjust. A camera can start recording. It all happens on its own.

When you leave, the lock can close on its own. Lights turn off. The thermostat shifts to save energy. Cameras switch to full recording. You don't have to touch anything.

You can create codes for guests. Set them to expire after a day. The log shows when they came in. No need to swap keys. No need to meet in person.

If someone tries to force the lock, alerts fire at once. Lights can turn on. Smart speakers can sound an alarm. You can call for help from the app.

Battery Care and Fixes

Cold weather drains batteries faster. Expect four to six months in harsh winters. In mild weather, you can get up to 12 months. Standard AA batteries cost about $5 to $10 for a pack.

Keep the sensor clean. Wipe it with a dry cloth each month. Check the bolts once a year. Make sure the door still lines up with the lock. Wood doors can swell in summer.

If the fingerprint scanner won't work, wipe it dry. Re-train your fingerprint if needed. Try a different finger. If the PIN fails, check the battery level first. A low battery can make the keypad slow.

If the app won't connect, check your Wi-Fi. The lock needs a 2.4 GHz network. It won't work on 5 GHz only. Restart your router if needed.
