Fingerprint Door Locks

Every lock in this range opens with a fingerprint — and with a keypad code, an RFID card or fob, your phone, or a mechanical key if you ever need one.

These are our own SDL and Loqee locks, which means a 12-month warranty handled here in Australia, spare parts kept in stock, and free shipping Australia-wide on every model.

How a fingerprint door lock works

A fingerprint door lock replaces the keyhole with a small sensor set into the handle or the lock body. You enrol a finger once, and the lock stores a mathematical template of the ridge pattern — not a photograph of your fingerprint. From then on, touching the sensor unlocks the door in about a second.

Enrolling a new person takes under a minute, either at the lock using the admin passcode or from the TTLock app. Deleting them is just as quick, and that is the practical reason fingerprint access suits share houses, holiday rentals and offices: when someone moves out you delete a finger, instead of re-keying a lock and cutting new keys.

How many fingerprints a lock stores varies by model. The number is listed in the Specification section of each product page above.

What happens when a fingerprint will not read

Wet hands, a fresh cut, cold fingers or a worn ridge pattern will occasionally fail to read. Every lock we sell is 5-in-1, so there are four other ways in:

  • A keypad passcode
  • An RFID card or key fob (Mifare 13.56 MHz)
  • The TTLock app on your phone, over Bluetooth
  • A mechanical key

That last one matters more than people expect. A fingerprint lock with no mechanical override is a lock you cannot open when the batteries go flat. Every lock in this range has one.

Which fingerprint lock fits your door?

Fit is the single most common reason a smart lock has to go back. Start from what is on the door now, not from the model you like the look of.

Timber, composite and standard entry doors
  • Latch (tubular) lock with a lever handle — the SDL-H1 Smart Compact. Wireless installation, no wiring to run. Best suited to internal doors, home offices, garages, storerooms, wine cellars and side entries.
  • Mortise lock body with a lever handle — the SDL-H2 Smart Medium. It replaces the mortise mechanism itself, which is what makes it suitable for front and main entry doors.
  • Deadbolt only, no handle — the SDL-T1 Smart Deadbolt. Fully automatic locking and a handle-free look, fitted to a standard deadbolt cut-out.
Aluminium and narrow-stile doors — sliding, swing and commercial

Narrow-stile doors are sized by the stile: the vertical frame section on the lock side of the door, beside the glass. Measure it before you order. A 43 mm lock will not go into a 35 mm stile, and no amount of goodwill changes that.

The four measurements to take before you order
  1. Stile width — the width of the vertical frame section on the lock side of the door. Each model's stile requirements page above shows exactly where to measure.
  2. Backset — the distance from the edge of the door to the centre of the existing lock hole. Our backset calculator works it out for you.
  3. Door thickness — measured across the edge of the door.
  4. Handing — which side the hinges are on, and which way the door swings.

Full dimensions are on the mortise and latch specifications and slim swing and sliding mortise specifications pages. If any of it is unclear, email a photo of your door and your current lock to sales@smartdoorlocks.com.au and we will tell you what fits — it is faster than guessing, and it is free.

Things to check before you buy

1. Where the door is, and what the weather does to it

A front door under a deep verandah and a gate in full sun are different problems. If the lock will be rained on or sit in direct sun, check the IP rating and the water-resistance notes in the Specification section of the product page. For gates and fully exposed openings, start with our smart gate locks instead — they are built for it.

2. Screen doors and security doors

If a screen door or security door closes over the top of your main door, the lock has to clear it. Check the external depth of the lock in the Specification section against the gap you actually have. Slim and low-profile models are usually the answer, but measure the gap first rather than assuming.

3. How you will actually use it

For a family home, the useful features are multiple user profiles and a record of who came and went. For an Airbnb or short-stay rental, it is time-limited and one-time passcodes you can issue and expire without ever meeting the guest. For an office or commercial site, it is a more robust handle set and, often, a DDA-compliant lever. These are different locks, and the difference is worth thinking about before you buy rather than after.

4. Remote access, and what it costs

Every lock here has Bluetooth built in, which covers you when you are standing at the door. Unlocking from anywhere, seeing the access log remotely, or issuing a code to someone who is not there yet requires a Wi-Fi gateway — a separate plug-in device, one per home, not one per lock.

One thing worth knowing up front, because nobody else mentions it: the TTLock free tier limits ad-hoc passcodes to five per month. For a household that is irrelevant. For a rental turning over guests weekly it is not, and it is better to know now.

5. Funding and accessibility

Keyless entry is often easier for people with limited grip or dexterity, and smart locks may qualify for NDIS assistive technology or home modification funding depending on your plan and your goals. We cannot approve funding or advise on your plan — talk to your plan manager or occupational therapist — but we are happy to supply the product detail they will ask for.

Apps, smart home and what these locks do not do

Most models run on the TTLock app; a few run on Tuya / SmartLife. The app is where you add and remove users, issue passcodes, and read the access log.

With a Wi-Fi gateway added, the locks work with Amazon Alexa and Google Assistant, and Control4 integration is available via API.

Being straight about the limits, because it saves everyone a return:

  • No native Apple HomeKit. A HomeBridge workaround exists, but it is not something we support out of the box.
  • No Z-Wave and no Zigbee.
  • Matter and Thread are on the roadmap, with no date we are willing to promise.

Setup guides for the gateway and the app are in our help centre.

Shipping, warranty and spare parts

  • Free shipping Australia-wide on every fingerprint door lock in this range. Standard delivery is 3–8 business days; express is 1–3.
  • A 12-month warranty on every lock, in addition to the rights you have under the Australian Consumer Law — never instead of them. Details on our warranty page.
  • Spare parts are held in Australia. If a component fails, it can usually be replaced rather than the whole lock — which is the practical difference between buying from an Australian company and buying from an overseas seller.
  • Australian support by phone and email, from people who know these specific locks.

Still deciding?

Take the Lock Recommendation Quiz — it takes a few minutes, asks about your door and your measurements, and narrows the range down to the models that will actually fit.

Or send a photo of your door and your current lock to sales@smartdoorlocks.com.au, tell us what you want it to do, and we will tell you which lock to buy. We would rather do that than process a return.

If a fingerprint is not the deciding factor, browse the range by shape instead: smart handles, smart deadbolts, slim locks for narrow-stile doors, digital door locks, or the smart keybox for situations where a lock cannot be installed at all.
