About this lock
A weatherproof lock with a fingerprint reader on both sides — the detail that matters on a gate, where there is no hallway to leave a key in. You go out the same way you came in, with nothing in your pockets. Rated IP66 by the manufacturer: dust-tight and protected against powerful water jets, so the Kezvion gate lock belongs on a front gate, side gate or courtyard door in direct rain and sun.
Will it fit your gate?
This is a surface-mounted rim lock, not a mortise. Nothing is cut into the upright: the body bolts to the inside face of the gate and the keeper screws to the frame opposite — which is what makes it practical on steel or aluminium gates where a mortise pocket is not an option. Keypad panel 170 × 58 × 35 mm, lock body 130 × 100 × 42 mm, keeper 100 × 40 × 35 mm, 60 mm backset to the 30 mm brass cylinder. Suits material 20–65 mm thick in steel, timber or stainless steel; handing is reversible. The dimensioned drawing is in the photos, and the sizing guide shows where to measure.
Ways to unlock
- Fingerprint, both sides.
- Keypad code — anti-peep layout so a bystander cannot read your code off the panel.
- RFID card — for regular visitors.
- Mechanical key — the override.
- App and gateway on the app versions (Bluetooth and Wi-Fi).
Good to know
- Compliance marks (CE, FCC, RoHS) are 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
A gate upright is narrower than a door, so the panel width is what decides here, not a mortise code. Check the drawing against your upright, then confirm the thickness.

Read this before you order
The version in stock is the standard keypad model — no app. If you want Tuya or TTLock app control on a gate, message us first so we get you the right unit. Ordering this one and expecting your phone to open it will disappoint you.
IP66 is a weather rating, not a security rating. It says nothing about how hard the lock is to force. On an exposed gate, pair it with a gate frame and hinges that are worth locking.
Voice prompts. The Tuya version speaks nine languages including English. The TTLock version is English only.
Voice assistants need a gateway and are only available on the app versions.
CE, FCC and RoHS marked according to the manufacturer (documentation being verified); no UKCA marking is claimed. Ask us before ordering if you need compliance paperwork.

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.
Can I really leave this out in the rain?
That is what IP66 means and what the manufacturer states — direct rain and sun. It is the reason to choose this lock over the rest of the range.
Will it fit a steel gate upright?
The panel is 34 mm wide, which is narrow enough for most steel and aluminium gate uprights. Measure the flat face of your upright before ordering.
Does it open from the inside without a key?
Yes — there is a fingerprint reader on the inside face too, which is the whole point on a gate.
Can I let a delivery driver in?
On the app versions, yes: issue a code valid for an hour. The standard version in stock has no app, so you would set a permanent or shared code instead.
What about the summer heat?
It is built for outdoor use, but no lock enjoys full afternoon sun in a Queensland summer. Mounting it on a shaded face of the gate will extend the life of the seals and the batteries.
