Smart Door Lock CSH-INDCB-017: Fingerprint & Latch Control

Question: How do fingerprint access and the thumb latch work on the Smart Internal Door Lock with Fingerprint?

Answer:

This lock combines app-controlled fingerprint access with a thumb latch that determines how the lock behaves. Here’s how to set it up and use it:

 Fingerprint Setup

• Fingerprints must be registered via the app

• You can save up to 20 fingerprints:

  • First 3 = Administrators

  • Next 17 = Regular Users

• To add a new admin once full:

  • Delete an existing admin in the app

  • Then add the new fingerprint

Thumb Latch Positions

Locked Position (Horizontal):

• Lock auto-locks 5 seconds after unlocking

• Only admin fingerprints can unlock

• Regular User fingerprints won't work

Open Position (Vertical):

• Lock stays unlocked after access

• Anyone can open from outside without fingerprint

• To lock: Scan fingerprint twice within 3 seconds

  • Both admins and regular users can then unlock

 Unlocking the Door

• Simply touch the sensor with a registered fingerprint

• No need to "wake" the sensor

• After unlocking:

  • Lock auto-locks after 5 seconds (if in locked mode)

  • Stays unlocked (if in open mode)

Leaving the House Securely

1. Turn latch to open before leaving

2. After exiting, either:

   • Turn latch back to locked, then close the door

   • Or close the door while latch is open, then
     scan fingerprint twice in 3 seconds to lock

Fingerprint Errors & Lockouts

• 5 failed attempts =

  • 10-second alarm

  • 2-minute lockout

  • No lights or unlock from inside/outside

• Use app only to unlock during lockout

App Connection Tip

If you see:
"Tap to connect to the device"
→ Just move closer and tap again — no need to wake the lock.
