Smart Lock C33 New, open box
Get a grip. Leave the key in your pocket.
A Wi-Fi smart lever lock for a front or side door. It reads a fingerprint at the handle, takes a code at the keypad, opens from the app or an encrypted eufy NFC card, and keeps a physical key as backup. It talks straight to the eufy app over its own built-in Wi-Fi, so there is no HomeBase or bridge to add.

Battery life is eufy's own rated figure under its stated assumptions; actual endurance varies with use, network conditions, temperature and battery quality.
What it does well.
Smart Lock C33: the features that matter in everyday use.
No hub to add
Direct built-in Wi-Fi connects the lock straight to the eufy app. eufy's own comparison table lists no HomeBase requirement for this model.
A lever, not a deadbolt
This replaces a lever handleset, not a deadbolt or a mortice/euro-cylinder lock. It carries an ANSI/BHMA Grade 3 residential hardware rating.
Measure before you order
eufy publishes a bore hole of 2 1/8 in, a backset of 2 3/8 in or 2 3/4 in, and a door thickness of 35–55 mm (exact T85L0 user guide). Check your own door against these first.
The honest details
Before you buy.
- It's a lever lock, not a deadbolt. It replaces a lever handleset. If you specifically want a deadbolt, this isn't that product.
- The weather rating is IP53. eufy's own figure. That covers dust and spraying water, not a fully exposed, driving-rain spot.
- No Apple Home or Matter. eufy's own FAQ states it isn't compatible with these yet. It works with Amazon Alexa and Google Assistant.
- Direct Wi-Fi and device integration are separate. The lock connects directly to Wi-Fi and supports integration with eufy doorbells and cameras. This does not mean it pairs to a HomeBase: eufy's T85L0 compatibility row marks HomeBase Mini, HomeBase 3 and HomeBase 2 unsupported.

New, explained.
What the condition label on this listing actually means.
What Open Box means
A new unit whose box has been opened and repackaged. It has not been used or installed.
Who did the work
The box was opened and repacked; the unit itself is untouched. We describe the packaging and the published spec sheet only.
How it arrives
In its original carton, opened and resealed, with every accessory listed below and our own 12-month warranty.
Right for you if
- Your door measures within the published bore, backset and thickness range.
- You want a lever lock with fingerprint, keypad, app and NFC options, plus a physical key backup.
- You use Amazon Alexa or Google Assistant, or neither.
- The door is sheltered rather than fully exposed to driving rain.
Probably not for you if
- You need a deadbolt or a mortice/euro-cylinder replacement.
- You run Apple Home or Matter and need the lock in it.
- Your door falls outside the published bore, backset or thickness range.
- The door is fully exposed to horizontal rain or extreme weather.
Plan your setup.
What you need
Before you bring it home
The C33 replaces a lever handleset, not a deadbolt. It uses eight AA batteries and its own Wi-Fi connection to the eufy app, with no HomeBase required. For card entry, use supported encrypted eufy NFC cards; an ordinary bank card or transport card is not a substitute.
- Measure your door first. Check bore hole (2 1/8 in), backset (2 3/8 in or 2 3/4 in) and door thickness (35–55 mm (exact T85L0 user guide)) against eufy's published figures before you order or fit anything.
- Complete the assembly, then insert the batteries. Follow the T85L0 guide: fit the exterior and interior assemblies, connect the cable, fasten screws and fit the silicone plug, then insert the eight AA batteries. Leave the battery cover off until app setup is complete. USB-C supplies emergency power only.
- Pair it in the eufy app. The lock connects to your Wi-Fi directly; there is no HomeBase step in that process.
- Enrol your unlock methods. Add fingerprints (up to 50), set passcodes (up to 100), register a compatible encrypted eufy NFC card, and keep the physical key somewhere known as backup.

Questions people ask.
Do I need a HomeBase to use this lock?

Is this a deadbolt?
No. eufy's own FAQ describes it as a smart lever lock that replaces a lever handleset, not a deadbolt or a mortice/euro-cylinder lock.
What size door does it fit?
eufy publishes a bore hole of 2 1/8 in, a backset of 2 3/8 in or 2 3/4 in, and a door thickness of 35–55 mm (exact T85L0 user guide), on wood or metal doors. Measure your own door against these before ordering.
Does it work with Apple Home?
eufy's own FAQ says it's not compatible with Apple Home or Matter yet. It works with Amazon Alexa and Google Assistant.
When will it ship, and what does delivery cost?
We do our best to get orders out the same day. Same-day to 1 business day is our typical dispatch time from Townsville. During busy periods it can extend, though that is rare. Australia Post Express is included on every order over $99.00. Under $99.00 it is $9.95 tracked or $12.95 Express.
Who covers the warranty?
We do. CamGuard Australia is an independent importer and reseller, and this product carries our own 12-month warranty. It is not a manufacturer warranty. Your rights under Australian Consumer Law apply on top. Faulty or not as described inside that year and we cover the return postage.

Smart Lock C33, new, open box.
Five ways in, one lever, no hub to add. Exactly as described above, our 12-month warranty. If that is the trade you want, this is the listing.
The door roster for guests, groceries and forgotten keys.
This page treats the C33 like a Queenslander housewarming host: your thumb opens the lever while both hands hold groceries, five entry methods manage the RSVP list, and the opened retail box is the invitation envelope that already lost its seal.
Arrival scene · thumb on the lever
The fingerprint reader is where your hand already goes.
Residents: grip and enter
The fingerprint sensor sits in the handle grip. The C33 can store up to 50 fingerprints, so the unlock action fits the natural motion of pressing the lever.
Guests: give them a code
Create and manage up to 100 passcodes in the eufy app. Anti-Peep lets extra digits surround the real code so somebody nearby cannot simply copy the sequence.
Closing time: countdown auto-lock
Set the countdown auto-lock so the host does not have to wonder whether the last person pulled the door shut and remembered the lock.
Attendance thread · built-in Wi-Fi
The lock posts its own updates. No hub chaperone.
Door: unlocked using an enrolled method.
App: real-time notification received.
House: event history saved for review.
Door: auto-lock countdown complete.
A quick housewarming only happens on the right door.
Wrong address: deadbolt, mortice or euro cylinder.The C33 replaces a standard lever handleset. It is not a smart deadbolt and is not designed to replace mortice-lock or euro-cylinder architecture. The advertised roughly 15-minute, no-drilling installation assumes a matching, standard pre-bored door, measure first.
Shelter gets an invitation. Sideways rain does not.
Welcome: sheltered exterior door
The IP53 rating suits a doorway under cover where the lock is protected from direct, driving rain.
Declined: exposed gate or storm face
IP53 is not full weatherproofing. Do not install it where an exposed gate or doorway takes direct Queensland downpours.
8 × AA includedRated for up to 8 months; real use and conditions affect battery life.
Alert at 20%The lock warns when battery capacity is getting low.
Emergency ride homeUSB-C provides emergency power only; it does not recharge the AA batteries. A physical key remains the backup.

Quick answers from the host.
What exactly does Open Box mean here?
The lock is new and has never been used. Its retail box was opened and the product repacked, so it is not factory sealed. It is not refurbished or renewed.
Does it need a hub or subscription?
No. Built-in Wi-Fi connects it directly to the eufy Security app. A HomeBase, bridge and paid subscription are not required for its core app functions.
Can it replace my deadbolt?
No. This is a lever handleset replacement, not a deadbolt. Confirm the bore, backset, thickness and lock architecture before ordering.
Can I recharge it through USB-C?
No. The lock runs on the included eight AA batteries. USB-C is an emergency power input if those batteries are flat; it does not recharge them.
Can it stay on a fully exposed gate?
No. IP53 calls for a sheltered doorway and is not suitable for an exposed gate or direct driving rain.
