TTLock gateway: when you need one and how to connect it

By Ribat · Updated 7 Nov 2026 · 6 min read

You need a TTLock gateway when you want to control a lock from anywhere. Remote control takes four things: the lock, a G2 or other TTLock-approved gateway, an internet connection and a TTLock account. Without a gateway, time-based codes still work on the lock, but changing them needs a Bluetooth phone at the door.

Key takeaways

  • Remote control needs four things: a TTLock lock, a G2 or other TTLock-approved gateway, internet and a TTLock account.
  • Without a gateway, time-based codes keep working. TTLock lists remote unlock and remote code changes as gateway-only.
  • The G2 uses 2.4 GHz Wi-Fi. TTLock's app says 5G is not supported, so choose your router's 2.4 GHz network.
  • TTLock gives the gateway's range as 10 meters with no obstruction. Add the lock and gateway under the same TTLock account.
  • TTLock's and Sciener's own pages we checked on 7 November 2026 list no G5, so this guide gives no G5 specs.

What remote control needs

Remote control of a standard TTLock lock takes four things. If one is missing, you cannot open the door or change a code from somewhere else.

  • A TTLock lock. A standard TTLock lock talks only over Bluetooth, so it cannot reach the internet by itself.
  • A G2 or other TTLock-approved gateway. A gateway is a small plug-in box. It connects your lock to the internet.
  • An internet connection. The G2 joins your Wi-Fi.
  • A TTLock account. Add the lock and the gateway under the same account. TTLock only links them automatically when they share an administrator account.

For remote unlock, there is one more step. The “Remote Unlock” setting must be on in the lock’s settings in the TTLock app.

What works without a gateway, and what doesn’t

Time-based door codes work without a gateway. Anything you want to do from far away needs one. Time-based codes are stored on the lock, so they also keep working if your connection drops.

TTLock features with and without a gateway

What you want to doWith a gatewayWithout a gateway
Guest enters a time-based codeYesYes
Unlock with the phone app over Bluetooth, at the doorYesYes
Unlock from anywhereYesNo
Edit or delete a code remotelyYesNo
Create a custom code remotelyYesNo
Manage cards or fingerprints remotelyYesNo
Upload unlock records to TTLock automaticallyYesNo
Change lock settings remotelyYesNo
Check lock time and status remotelyYesNo

Without a gateway, changing or deleting a code means someone must be near the lock with a phone and Bluetooth. TTLock also says changes by gateway or Bluetooth only work on locks with “V4 passcode” support, so check this with your lock supplier.

One rule applies either way. TTLock says a time-limited code must be used once within 24 hours of its start time, or it stops working.

So a gateway is worth it when nobody can easily reach the door. If staff are on site and can walk to the lock with a phone, you may be fine without one for now.

G2 vs G5: what TTLock’s own documents confirm

We cannot give you a confirmed G2 vs G5 comparison. TTLock’s and Sciener’s own pages that we checked on 7 November 2026 do not list a G5. Sciener’s hardware page shows the G2, G3/G3P and G4. TTLock’s developer documents number gateways from G1 to G4.

G1Wi-Fi, 2.4 GHzListed in TTLock’s help center
G2Wi-Fi, 2.4 GHz, 802.11 b/g/nUSB-C power, 5V/500mA, 70 x 70 x 26 mm
G3/G3PWiredSciener’s product name adds PoE power, which means power through the network cable
G44GNamed by TTLock as a 4G gateway
G5Not listedNo specs confirmed, so we give none

Documents can lag behind new products, so this does not prove that a G5 won’t work. If a seller offers you one, check these first:

  • Does G5 appear on the gateway type list in your TTLock app?
  • Can the seller show the manufacturer’s documentation, including which Wi-Fi bands it needs?
  • Is it TTLock-approved for your lock model?

How to connect a G2 gateway

You connect a G2 from the TTLock app. These steps follow TTLock’s help center and G2 guide. Screens may differ a little between app versions.

  1. Add your lock first Add the lock to the TTLock app, using the account you plan to keep.
  2. Open the gateway page Tap ≡, then Gateway, then + at the top right.
  3. Choose the type Select G2 (Wi-Fi) from the list.
  4. Power the gateway Plug it in. When the light flashes red and blue in turn, tap Next.
  5. Pick your gateway Tap + next to the gateway the app finds.
  6. Connect it to Wi-Fi Choose a 2.4 GHz network, enter its password, name the gateway and tap OK. The app warns that “5G is not supported”. That means 5 GHz Wi-Fi, not mobile 5G.
  7. Wait for the scan The app looks for locks that belong to you. It says this may take about 3 minutes.
  8. Check the result The gateway’s page should show Status as Online, your Wi-Fi name and at least one nearby lock.
  9. Turn on Remote Unlock Switch it on in the lock’s settings in the app. If you skip this, remote unlock will fail.

If adding the gateway fails or times out, power it off and try again. The light tells you where it stands.

Where to place the gateway

Place the gateway within 10 meters of the lock, and closer if anything stands between them. TTLock’s figure is “10 meters (no shelter)”, so treat it as the best case. The other limits are practical:

  • It must reach your Wi-Fi as well as the lock.
  • The G2 needs USB power, so choose a spot near an outlet where nobody will unplug it.
  • Long corridors may need more than one gateway. A lock can link to several, and TTLock picks the one with the best signal for each remote command.

The TTLock web system shows each lock’s gateway, Wi-Fi and signal. TTLock’s developer documents rate signal like this: stronger than -75 is strong, -75 to -85 is medium, and weaker than -85 is weak. Numbers closer to zero are stronger. The reading normally refreshes about every 10 minutes, so wait before judging a new position.

We did not find a limit on locks per gateway in TTLock’s own documents, so ask your supplier if you plan to cover a whole floor.

How to check a lock is online

A lock counts as online when it is connected to a gateway or has Wi-Fi built in. For a gateway lock, check in the TTLock app.

  1. Check the gateway Tap ≡, then Gateway. Each gateway shows as Online or Offline.
  2. Check nearby locks Open the gateway and confirm that Nearby Locks includes your lock.
  3. Check the lock Open the lock’s settings. Gateway details appear there once it is connected.
  4. Run a real test Ask someone at the door to confirm while you try a remote unlock.

The status can lag. TTLock says a gateway going offline normally takes about 10 minutes to show. The app only sends an alert once a gateway has been offline for more than 30 minutes, so a short dropout may pass without notice.

How a gateway-connected lock maps into Ribat

Once TTLock shows the lock connected, you can control it remotely from Ribat. Do the TTLock setup first, because Ribat uses that same account.

  1. Link your TTLock account Sign in to TTLock from Ribat.
  2. Map each lock Assign each lock to its room or unit.
  3. Control it from Ribat Each booking gets its own time-limited code. After a code is generated, you can extend it, shorten it or move it to new check-in and check-out times without changing the code.

Gateway-free locks are also supported, with a manual or Bluetooth step, so a gateway does not have to come first. We confirm what your lock model needs during setup.

Ribat is a fit if you run bookings across several channels and want codes tied to each stay. It starts at a flat $49 a month per property for 1–2 rooms, and Ribat takes no booking commission. There is a 14-day free trial. If you only want remote access to your own door and take no bookings, the TTLock app alone is enough. See the TTLock integration for more.

Frequently asked questions

Do I need a gateway for TTLock door codes?

Not for time-based codes, because they are stored on the lock and keep working without internet. You need a gateway to unlock the door or change a code from somewhere else.

What is the difference between the TTLock G2 and G5?

We cannot confirm one. TTLock's and Sciener's own pages we checked on 7 November 2026 cover the G2 but list no G5. The G2 uses 2.4 GHz Wi-Fi. If you are offered a G5, ask for the manufacturer's documentation first.

Why won't my G2 gateway connect to Wi-Fi?

Check that you chose a 2.4 GHz network, because the G2 does not support 5 GHz. A red light means a network failure. If adding the gateway times out, power it off and try again.

How far can the gateway be from the lock?

TTLock gives the range as 10 meters with no obstruction. Treat that as the best case, and place the gateway closer if walls or doors stand between it and the lock.

How do I check that my TTLock lock is online?

In the TTLock app, open the Gateway page and check that the gateway shows Online and that its nearby locks include yours. The lock's settings also show its gateway. A short remote test confirms it.

Can one lock use more than one gateway?

Yes. TTLock says locks and gateways can be linked many-to-many. When you send a remote command, its system picks the gateway with the best signal to that lock.
