An Eufy smart lock is worth considering if you want keyless entry from a brand known for home-security gear, provided the model fits your door and keeps a mechanical key override. Fitted in Sydney, any smart lock typically costs about $600, within a range of $345–$920.

Eufy smart lock review: what to check first
A fair review starts with the points that decide whether the lock suits your home. Use this table before you read any feature list.
| Check | What to look for | Why it matters |
|---|---|---|
| Door fit | Thickness, backset and existing holes match the spec sheet | A poor fit means extra joinery and a higher quote |
| Entry methods | Which of code, fingerprint, app or key your model offers | Different households need different ways in |
| Backup | A mechanical key or another override | Prevents a lockout when the battery fails |
| Connection | Whether it needs Wi-Fi, Bluetooth or a separate bridge | Affects remote access and total cost |
| Weather rating | Suitability for an exposed door in sun, rain or coastal air | Salt and heat age electronics faster |
| Support | Local availability of parts and help | A good lock still needs service over time |
Eufy door lock: entry methods and features
Eufy sells several lock styles, so list what you need before you pick a model.
- Keypad entry: good for family and visitors, because you can issue a code and delete it later without re-keying the door.
- Fingerprint entry: quick when your hands are full, but check how the reader copes with wet or dirty fingers.
- App control: useful for letting someone in while you are away, so confirm what your model needs for remote access.
- Mechanical key: a physical backup remains the safest fallback, so check that your model includes one.
- Auto-lock: handy for busy households, but test it carefully so it does not shut you out with the door open.
- Activity records: see who entered and when, which helps in rentals, share houses and with tradies.

Eufy smart lock security: what a locksmith checks
- The door and frame: a rotten frame or loose hinge fails long before the electronics do, whichever brand you fit.
- The strike plate: after a house settles, a misaligned strike plate makes the motor work harder and drains batteries.
- Code habits: change default codes on day one and avoid birthdays and repeated digits.
- Old codes and accounts: delete guest codes after use and remove former tenants or housemates from any app.
- Extra protection: pair a smart lock with a deadbolt, which typically costs about $290 to install, for added mechanical strength.
- Software updates: keep the app and lock firmware current, as makers release fixes over time.
Eufy smart lock batteries and reliability
- Check the battery type and where it sits, since some designs make changing cells easier than others.
- Replace batteries early: do not wait for the last warning; battery life varies by model and use (indicative — check the product manual).
- Test the override: try the mechanical key once a year, because locks that never turn can stiffen.
- Weather and salt air: near the coast, rinse and inspect exposed hardware and keypads more often.
- Know your lockout options: a business-hours lockout typically costs about $205, rising to about $320 after hours.
- Keep a spare key with someone you trust; a standard key typically costs about $14 to cut.
Eufy smart lock installation: DIY or licensed locksmith?
| Approach | Suits | Watch out for |
|---|---|---|
| DIY fitting | Confident owners with a standard door | Misaligned latch, wrong backset, no testing of the override |
| Licensed locksmith | Older doors, deadbolt upgrades, several locks | Check the licence number and get an itemised quote |
- Licence check: locksmiths in NSW work under a Class 2 security licence, and a legitimate one asks for ID before working on your home.
- Rentals and strata: get written approval before replacing a lock on a tenancy or unit.
- Egress: NCC exit-door egress rules apply to some doors, so ask before you fit a lock on a fire or exit door.
- Compare other brands before you commit, because the best lock is the one that fits your door and habits: read our Samsung smart lock review, Yale smart lock review, Philips smart lock review and Aqara vs Lockly comparison.
- Keypad choices: see our digital and keypad door locks guide.
- Mechanical basics: our types of door locks guide explains the hardware behind the electronics.
Common mistakes to avoid with an Eufy smart lock
- Not measuring the door: check thickness and backset first, or you risk returning the lock.
- Removing the key override: a flat battery then means a locksmith call, not a quick fix.
- Leaving default codes: change them straight away and record who holds each one.
- Ignoring the frame: strengthen weak timber before fitting any lock.
- Forgetting old keys: if you keep any conventional locks, re-key them at about $75 each so earlier copies stop working.
