How to Add Fingerprints, Users and Codes to Your Smart Lock

Adding a user to your smart lock is the first thing most homeowners in Riyadh, Jeddah and Dammam want to do right after installation. A smart lock only becomes useful once you enrol your family's fingerprints, hand a temporary code to a guest or helper, and control exactly who enters and when. This practical Fixlr guide walks you through adding fingerprints, users, codes and cards to your smart lock, and managing them safely through an app like TTLock. ## Access methods and user types Most modern smart locks support several unlock methods at once and can hold 50–100 users: - **Fingerprint** — fastest, ideal for the family. - **PIN code** — 4–9 digits, great for guests and helpers. - **RFID card** — handy for kids and the elderly. - **App / Bluetooth** — unlock from your phone nearby, or remotely with a Wi-Fi gateway. - **Mechanical key** — for emergencies on most models. ### Admin vs. regular user Every smart lock has an Admin account that can add or remove users and change settings, plus regular users who can only open the door. Keep admin rights on one trusted phone and never share them. ## How to add a fingerprint 1. Enter the lock's management mode (long-press a button or enter the admin code + #). 2. Choose Add User, then Fingerprint. 3. Place and lift your finger at slightly different angles several times until enrolment completes. 4. Register the same finger twice under different names for better accuracy. 5. Test it immediately by closing and opening the door. Tip: clean the sensor and your finger first, and avoid wet or very dry fingers. ## How to add a PIN code Codes come in a few types: permanent (family), one-time (deliveries) and time-limited (helpers, guests). Enter management mode, choose Add Code, type and confirm the new code, then set its type and duration if available. Enable the anti-peep / random-digits feature if your lock has it, so onlookers can't catch your real code. ## How to add a user through the app App-based locks such as TTLock give you the most control. Install the official app (play.google.com/store/apps/details?id=com.tongtongsuo.app), create an account, and pair the lock over Bluetooth while standing next to it. You can then send eKeys, add codes, fingerprints and cards, and review the entry log. With a Wi-Fi gateway connected, you can add users or send codes from anywhere.

Create a temporary code or eKey that works only on set days and hours, then expires automatically — far safer than a key under the mat or a shared permanent code. ## Security tips - Choose strong codes; avoid 1234, 0000, birthdays or phone numbers. - Delete any code or fingerprint you no longer need. - Review the user list regularly. - Never share the admin account; lock the admin phone. - Update the lock's firmware from the app when prompted.
