About this lock
The lever-handle lock that removes the measurement most people get wrong. The Kezvion adjustable lever lock ships with a 60–70 mm adjustable latch, so it fits either common backset without you committing before you have measured. Available in silver or black.
Why the adjustable latch matters
Backset is the distance from the door edge to the centre of the handle hole — usually 60 mm, sometimes 70 mm. Order the wrong fixed latch and the lock simply does not go on. Here one latch covers the range and is set during installation. Door thickness and stile width still have to match — the sizing guide shows how to check.
Ways to unlock
- Fingerprint — stored on the lock, not in a cloud account.
- Keypad code — permanent, temporary or one-time.
- IC / NFC card.
- App — TTLock as standard (fingerprints, codes, cards, access log, shared keys). Prefer the Tuya version? Say so in the order note at checkout — same price. Message us before ordering if you need a specific one.
- Mechanical key, plus a USB-C emergency port on the outside — touch a power bank to it and the keypad wakes.
Good to know
- The manufacturer states this model is not waterproof: internal doors and sheltered entries only.
- Designed for timber doors.
- Compliance marking (CE) is stated by the manufacturer; documentation is being verified.
- Not certified for fire doors or required exit doors.

Backset CalculatorTwo questions, about a minute — find the exact mortise for your door
Two questions, about a minute. Keep a tape measure handy.
1Your door
Where is this lock going?
The gate lock suits that better
This is a door lock. For a gate, our SL-G1 has a 34 mm panel made for narrow gate uprights and fingerprint readers on both sides.
2Your measurement
Measure from the faceplate of your existing mortise to the centre of the square spindle hole. What does it read?
Order the 6085 mortise
60 mm backset, 85 mm centres. This is the one most 60 mm timber doors take.
Order the 4585 mortise
45 mm backset, 85 mm centres.
Order the 3585 mortise
If your door slides, order the 3585 hook bolt version instead — a straight bolt will not hold on a slider.
Order the 2885 mortise
If your door slides, order the 2885 hook bolt version instead.
You need a hook bolt
A straight bolt has nothing to grip on a sliding door. Measure your backset, then order the hook bolt version of that size — 2885 hook or 3585 hook.
Measure the mortise, not the door
Measure from the faceplate to the centre of the square spindle hole. The sizing guide shows it with a diagram.

Guides and installation
Check the size, then follow the guide
This one ships with an adjustable latch that covers both 60 and 70 mm backsets, so the measurement that usually decides everything matters less here. Check the door thickness and the stile width on the drawing before you order.

Read this before you order
No weather rating at all. The manufacturer states this lock is not waterproof. Internal doors and sheltered entries only. If your door catches rain, order the SL-G1, which is rated IP66.
It costs more than our Fingerprint & Code model, and it is not better in every way. What you are paying the extra for is the adjustable latch in the box, the higher user count and the twelve-month battery. That model adds a doorbell and more narrow-stile options for less money. Pick on what you actually need.
Remote access needs a gateway — a TTLock G2 for the standard TTLock version (not included, not sold by us). Bluetooth only out of the box.
Timber doors. The manufacturer lists wooden doors and room doors. For aluminium-framed, glass or sliding doors, look at the Long Handle and Push/Pull Handle models instead.
CE marked according to the manufacturer (documentation being verified); no UKCA marking is claimed. Ask us before ordering if you need compliance paperwork for a rental, a managing agent or a commercial fit-out.

Before you buy
Questions people ask about this lock
Fitting and measurement questions in depth live in the sizing guide. How to choose between our five types is in the buying guide.
Why is this dearer than the Fingerprint & Code model if it has no doorbell?
Because the adjustable latch is included, so there is no wrong option to order, and because it handles far more users. If neither matters to you, the Fingerprint & Code model is the better value.
Do I still need to measure my door?
Measure the thickness and the stile width. The backset is the one you can stop worrying about — the adjustable latch covers 60 mm and 70 mm.
Tuya or TTLock — which app?
We ship the TTLock version as standard — it has the better guest-access tools. If you would rather have Tuya, which integrates with more smart-home devices, say so in the order note at checkout; same price.
Can I put it on my front door?
Only if the door is sheltered by an eave, porch or roof. It has no waterproof rating.
How long do the batteries last?
About twelve months of normal household use, and the lock warns you before they run out.
