This guide covers the full installation and configuration of a typical Sciener smart lock, step by step, for a first deployment or as a refresher for staff. A single door is well within reach of a competent DIYer or handyman. For a large rollout, professional installation tends to pay for itself in reliability, because most support tickets trace back to a door that was not prepared correctly rather than to the lock itself.
Before you start
Gather what you'll need. The product documentation lists the exact parts for your model; in general:
- The lock and all supplied hardware (latch, strike, screws, batteries).
- The door, prepared to the correct thickness, backset and bore.
- A charged phone with the TTLock / Sciener app installed.
- Basic tools: drill, screwdriver, tape measure.
Confirm the door spec matches the lock before going further.
1. Fit the latch and strike
- Insert the latch into the door edge bore.
- Secure the latch face with its screws.
- Position the strike plate on the door frame so the bolt engages cleanly, and fix it in place.
- Test that the bolt extends and retracts smoothly with the door closed.
If the bolt binds here, the strike is misaligned — fix it now, before the electronics go on. Binding bolts are the single biggest cause of "the lock doesn't work" calls, so it is worth getting right at this step.
2. Mount the lock body
- Pass the spindle and any connecting cable through the latch.
- Place the exterior assembly on the outside of the door.
- Place the interior assembly on the inside.
- Tighten the mounting screws that draw the two halves together, then fit the interior cover.
Do not overtighten — you can crack a housing or pinch a cable. Route the connecting cable carefully as the halves come together.
3. Power up
Insert the batteries in the interior assembly. The lock will initialise and emit a confirmation tone. If nothing happens, check the battery orientation and that any internal connector is seated.
4. Bind the lock in the app
- Open the TTLock / Sciener app and sign in.
- Add a new lock and follow the Bluetooth pairing flow.
- Stand close to the lock while it pairs.
- Name the lock (for example, "Unit 12 — Front Door") so you can identify it later.
Set yourself as the administrator before adding anyone else.
5. Enrol users and credentials
- Add an administrator fingerprint and passcode first.
- Enrol regular users: fingerprints, passcodes and IC cards as needed.
- Test each credential at the door — do not assume enrolment succeeded.
- Set time limits on any temporary credentials.
6. Add a gateway (for remote access)
If the lock will be managed remotely:
- Plug in the gateway within Bluetooth range of the lock — about 10 m, away from metal obstructions.
- Add the gateway in the app and connect it to the 2.4 GHz Wi-Fi. Most gateways do not connect to 5 GHz networks, so confirm the band before you start.
- From the gateway settings, pair the lock(s) it will manage.
- Trigger a remote unlock to confirm the round-trip works.
Final checks at the door
Walk through these checks at the door:
- Every enrolled credential opens the door.
- Expired or unenrolled credentials are rejected.
- The mechanical key works as a failsafe.
- Remote unlock and alerts work (if a gateway is fitted).
- The lock reports battery level and is fresh.
- The door latches cleanly with no binding.
Document the administrator credentials and store a mechanical key off-site.
Where most installs go wrong
The same short list accounts for most callbacks: a binding bolt from an uncorrected strike misalignment, a pinched cable from drawing the halves together carelessly, a gateway placed out of range or on 5 GHz, and batteries that mix old with new. These are installation details that surface once the door is in daily use, and they are the reason most support tickets get raised.
