Get the app, add your lock.

Applies to: Connectivity on the product page reads “Bluetooth (TTLock)”.

1. 1Install TTLock and register with your phone number or email.
2. 2Turn on Bluetooth and stand within a metre of the lock.
3. 3Tap “+” (Add Lock) and choose “All Locks”.
4. 4Touch the keypad to wake the lock. It appears in the list with a “+” beside it — a lock already registered to another account will not appear at all. Tap it.
5. 5Name the lock. It now belongs to your account, and anyone else needs you to share access.
6. 6Add fingerprints, PIN codes and cards from the lock’s page. All of it is written over Bluetooth, so stay at the door while you do it.
7. 7Optional: to unlock or issue codes while you are away, add a G2 gateway — side menu → Gateway → “+”. Power the gateway until its light flashes red and blue, then pick your 2.4 GHz network and enter the password. Keep the gateway within about 10 m of the lock.

Without a gateway the lock is not on the internet. Passcodes still work — TTLock calculates them rather than sending them to the lock — but remote unlock is unavailable, and unlock records only reach the app when you next stand at the door.

Applies to: Connectivity reads “WiFi (TTLock)” — or reads “WiFi (TTLock or Tuya Smart)” and you ordered the TTLock version.

1. 1Add the lock exactly as for a Bluetooth lock — steps 1 to 5 above. A WiFi lock is still paired over Bluetooth.
2. 2Stay at the door, open the lock’s settings and find WiFi (some firmware labels it “Network”).
3. 3The app has the lock scan for networks over Bluetooth, and lists what the lock itself can see — not what your phone can see.
4. 4Pick a 2.4 GHz network and enter its password. The lock has no 5 GHz radio, so if your router broadcasts both bands under one name, split them or use a 2.4 GHz-only SSID.
5. 5Wait for the lock to report in — its page in the app then shows it online.
6. 6Add fingerprints, PIN codes and cards as usual. From here remote unlock, issuing and deleting codes, and unlock records all work from anywhere — no gateway.

A WiFi lock runs on batteries, so it does not hold the connection open — it wakes on a schedule and after each use, and a remote command usually takes a few seconds to land. If the lock’s settings offer a WiFi power-saving mode, turning it on lengthens battery life and lengthens that delay.

Applies to: Connectivity reads “WiFi (Tuya Smart)”, or you ordered the Tuya version. Every Tuya version in this range is a WiFi lock: it joins your network itself and needs no Tuya hub.

1. 1Install Tuya Smart and register with your phone number or email.
2. 2Connect your phone to the 2.4 GHz network the lock will join, and allow the app Bluetooth and location access — it reads the current network name from them.
3. 3Put the lock into pairing mode at the keypad: wake it and follow the lock’s manual — commonly * then #, or the admin code and then the network item in the lock’s menu. The indicator starts blinking.
4. 4Read the blink. Fast is quick pairing (EZ mode); slow is compatibility mode, where the lock puts up its own hotspot. Choose the matching mode in the app, and if one fails, switch the lock to the other and try again.
5. 5Tap “+” (Add Device). A lock in pairing mode usually pops up at the top of the screen; if it does not, choose Security & Sensors → Lock (Wi-Fi).
6. 6Enter the WiFi password and wait. In compatibility mode the app first asks you to join the lock’s own SmartLife-xxxx hotspot; your phone returns to your network once pairing finishes.
7. 7Name the lock, then add fingerprints, PIN codes and cards from its device page. Temporary codes and remote unlock run over WiFi.

Pairing fails for four reasons more often than all the others combined: the phone is on 5 GHz, the WiFi password contains special characters, the router is too far from the door, or location permission is off.
