A digital door lock replaces or backs up your key with a keypad, fingerprint reader, card or phone. Supplied and fitted in Sydney, one typically costs about $600, within a range of $345–$920 per lock.
This guide explains how keypad and fingerprint options differ, what they cost, which door they suit and where owners go wrong. For the wider picture, see our smart locks guide.
Key points
- A digital lock supplied and fitted in Sydney typically costs about $600 (range $345–$920).
- A keypad door lock is simple and suits shared access; a fingerprint door lock suits households that rarely share codes.
- Keep a mechanical key override, because a flat battery should never mean a lockout.
- In NSW, locksmiths work under a Class 2 security licence; ask for the licence number before work starts.
What is a digital door lock?
A digital door lock moves the control of your door from a metal key to something you know, hold or are. The table below defines the common terms you will meet when comparing models.
| Term | Meaning | Why it matters |
|---|---|---|
| Keypad door lock | Opens with a code you enter on buttons or a touchscreen | Easy to share and cancel codes for family, guests and tradies |
| Fingerprint door lock | Opens when the reader recognises a stored fingerprint | No code to forget, but check how the reader copes with dirty or wet hands |
| Digital lock | Any electronic lock that replaces or supplements a key | Covers keypad, card, fingerprint and phone-controlled models |
| Smart lock | A digital lock that also connects to an app or home system | Adds remote access, but also adds setup and battery needs |
| Mechanical override | A physical key slot kept as a backup | Protects you from a flat battery or an electronic fault |
Keypad door lock: how it works and who it suits
A keypad door lock is the most common entry point into digital locks, because everyone understands a code.
- Short-term access: give a cleaner or tradie a code for one visit, then delete it instead of re-keying.
- Family use: children and older relatives do not need to carry keys that get lost.
- Weak codes: birthdays and repeated digits are easy to guess, so choose a code that means nothing to anyone else.
- Wear on the buttons: on a front door that sees heavy use, the most-pressed keys can show wear, so change codes regularly.
- Weather exposure: a keypad in direct sun or salt air near the coast needs a finish rated for the conditions.
- Override key: keep a mechanical key in a safe place, not under the doormat.
Fingerprint door lock: pros, cons and fit
A fingerprint door lock suits people who want quick entry without remembering anything. Performance depends on the reader and on how clean the finger is.
- Fast entry: you walk up, touch the reader and the door opens, which helps when you are carrying shopping.
- No code to share: there is nothing for a visitor to overhear or copy, but there is also nothing easy to hand a guest.
- Reader condition: dirt, moisture or worn fingertips can cause misreads, so check how the model copes with real-life conditions.
- Backup methods: pick a model that also offers a code or key, so one failed fingerprint is never a lockout.
- Children and guests: a fingerprint door lock is awkward for short-term visitors, so pair it with a code option.
- Enrolment: enrol more than one finger per person so a cut or bandage does not lock them out.
Digital door lock cost in Sydney
These are Sydney prices as at October 2026, including GST. Your quote depends on the model, the door and the time of day.
| Job (Sydney, Oct 2026) | Price range | Typical |
|---|---|---|
| Digital lock, supplied and fitted | $345–$920 | $600 |
| Deadbolt installation | $170–$460 | $290 |
| Basic lock replacement | $140–$400 | $255 |
| Re-key, per lock | $52–$140 | $75 |
| Standard key cutting | $6–$34 | $14 |
- Model and features: adding fingerprint, card or app control usually moves a quote toward the top of the range.
- Door preparation: new cut-outs or a repaired frame add to the bill (indicative — get itemised quotes).
- Time of day: after-hours, weekend and public-holiday call-outs carry a surcharge that varies by locksmith.
- Number of doors: fitting several in one visit reduces repeat travel.
- Running costs: budget for batteries over the life of the lock (indicative — check the product manual).
- Old hardware: re-keying the locks you keep costs about $75 each, so old copies stop working.
Digital lock vs deadbolt and standard locks
| Option | Strength | Watch out for |
|---|---|---|
| Digital lock | Keyless entry and easy access control | Batteries, door fit and a working override |
| Deadbolt | Strong mechanical security at a typical $290 | Still needs keys that can be copied |
| Standard lock | Low cost and familiar | Worn pins and cheap knob locks on older doors |
- Combine them: a deadbolt plus a digital lock gives you both keyless entry and a strong mechanical bolt.
- Check the door and frame first: a rotten frame defeats any lock, however clever.
- Compare brands: see our Aqara vs Lockly comparison, Eufy smart lock review, Samsung smart lock review, Yale smart lock review and Philips smart lock review.
- Learn the basics: our types of door locks guide explains the mechanical side.
- Egress: NCC exit-door egress rules apply to some doors, so confirm with a locksmith before changing hardware on one.
- Renters and strata: get written approval before changing a lock on a unit or tenancy.
Digital door lock installation and licensing
- Licence check: locksmiths in NSW work under a Class 2 security licence, so ask for the licence number before work starts.
- ID check: a legitimate locksmith asks for ID or proof of residence before working on your door.
- Measure first: door thickness, backset and existing holes decide which models fit without extra joinery.
- Test the override: before the locksmith leaves, check the mechanical key works.
- Set up codes properly: remove factory default codes and record who holds each one.
- Cancel old keys: have any retained locks re-keyed so earlier copies stop working.
Common mistakes to avoid with a digital door lock
- Skipping the override: a flat battery with no mechanical key means a lockout call, which typically costs about $205 in business hours.
- Leaving default codes: factory codes are published, so change them on day one.
- Ignoring the strike plate: a misaligned strike plate after the house settles makes motors work harder and batteries drain faster.
- Buying on features alone: a model that does not fit your door costs more than the one that does.
- Never deleting guest codes: old codes are the digital version of a spare key under the pot plant.
Digital door lock FAQs
How much does a digital door lock cost in Sydney?
A digital door lock supplied and fitted in Sydney typically costs about $600, within a range of $345–$920 per lock (October 2026). The price depends on the model, the door and any preparation work, so ask for an itemised quote before you commit.
Is a keypad door lock or a fingerprint door lock better?
A keypad door lock is better for shared access, because you can issue and delete codes. A fingerprint door lock is better when only a few people use the door. Many models offer both, plus a key override, which is the safest combination.
Are digital locks secure?
A digital lock is only as secure as its code habits, its door and its frame. Change default codes, delete old ones and fix weak frames. For forced-entry resistance, many owners pair a digital lock with a deadbolt.
Do I need a locksmith to fit a digital door lock?
Fitting and aligning the lock is best left to a licensed locksmith. In NSW, locksmiths work under a Class 2 security licence, so ask for the licence number. You can manage codes and batteries yourself afterwards.
