A quick answer: most locksmith jobs are faster than people expect
For many New Zealand homes, a locksmith job takes 15 minutes to 2 hours once the locksmith is on site. Simple jobs such as rekeying a lock, cutting keys, or repairing a minor issue are often quick. Bigger jobs like replacing multiple locks, fitting digital locks, or dealing with a jammed deadbolt can take longer.
The total time also includes travel, diagnosis, and any follow-up for parts. If you need an urgent call-out, the locksmith may arrive quickly but still need extra time to open, repair, or replace the lock properly.
If you are planning a reno, a move, or an insurance-related change, it is worth asking for an estimated labour time and whether the quote includes call-out fees, parts, and GST.
Typical timeframes for common locksmith jobs
The actual time depends on the lock type, the condition of the door, and whether the locksmith is working on a standard residential property or something more complex. As a rough guide:
| Job | Typical on-site time | Notes |
|---|---|---|
| Cut duplicate keys | 5–15 minutes | Usually quicker if the key blank is standard |
| Rekey one lock | 15–30 minutes | Faster if the lock is common and in good condition |
| Rekey several locks to one key | 30–90 minutes | Depends on number of cylinders and lock types |
| Fix a sticky latch or misaligned lock | 20–60 minutes | Door alignment can add time |
| Repair a broken lock mechanism | 30–90 minutes | May take longer if parts are worn or obsolete |
| Lockout / gaining entry | 10–60 minutes | Can be quicker or much longer depending on the lock and door |
| Install a new deadbolt | 30–90 minutes | Timber doors are usually easier than steel or composite doors |
| Install a digital smart lock | 45–180 minutes | Extra setup and testing often needed |
| Change multiple locks after a move or tenancy change | 1–3 hours | More time if many doors, keys, and access points are involved |
| Commercial lock or restricted key system work | 1–4+ hours | Often more complex than standard home jobs |
These are broad estimates rather than guarantees. A straightforward job on a standard timber door in good condition may be done quickly. Older homes, seaside properties, and damaged doors often take longer.
What affects how long locksmith work takes?
Several practical factors can change the timeline quite a bit.
1) The type of lock
A basic mortice lock, a deadbolt, a patio door lock, and a smart lock all have different mechanisms. Simple mechanical locks are usually quicker to service than electronic or high-security systems.
Some lock types can be opened or rekeyed on site with standard tools. Others may need:
- special parts
- manufacturer-specific codes or cylinders
- more careful fitting to maintain security
- time-consuming testing after installation
2) The condition of the door and frame
Lock issues are often really door issues. If the door has dropped, swollen, or twisted, the locksmith may need to adjust hinges, latch alignment, or strike plates before the lock works properly.
This is common in New Zealand after:
- winter moisture and damp weather
- summer heat affecting timber movement
- coastal corrosion around exposed hardware
- older villas and bungalows with doors that have settled over time
A quick lock repair can become a longer job if the door itself is not lining up.
3) Whether the locksmith has the right parts with them
Many locksmiths carry common cylinders, keys, latches, and hardware, but not every brand or finish is kept on the van. If the lock is unusual, discontinued, or high security, the job may need a return visit.
That is one reason to describe the lock clearly when booking. If possible, send:
- photos of the lock and door edge
- the brand name or model number
- a brief description of the problem
- whether the lock is jammed, broken, or just difficult to use
4) Access and site conditions
The more accessible the lock, the faster the work. A straightforward front door is much quicker than:
- a gate lock at the rear of a property
- a lock in a tight apartment entryway
- a tenant property where keys or access cards are missing
- a commercial site with layered access controls
If the locksmith has to work after hours, in rain, or in poor light, that can also slow things down.
5) Security checks and proof of authority
A good locksmith will take care to confirm they are dealing with the right person before opening or changing locks. This is normal and important.
Be ready to show:
- photo ID
- proof you live there or are authorised to act for the owner or body corporate
- tenancy or agency details if relevant
This is not just paperwork. It protects everyone involved and can avoid delays if the locksmith cannot verify authority straight away.
Common jobs and what to expect
Rekeying locks
Rekeying changes the internal pins or tumblers so old keys no longer work. It is often faster and cheaper than replacing the whole lock, especially after moving house or changing tenants.
Typical time:
- one lock: about 15–30 minutes
- several locks: about 30–90 minutes
Rekeying is usually efficient if the lock is standard and in good condition. It may take longer if the locksmith needs to remove and service tired hardware.
Emergency lockout service
If you are locked out, time can vary a lot. A simple residential lockout might take only 10–20 minutes once the locksmith arrives. A more secure lock, a damaged cylinder, or a door that has swollen shut may take much longer.
For emergency jobs, the biggest time variable is often response time, not the on-site work itself. In busy periods, after-hours, or in smaller towns, you may wait longer for arrival.
Lock repair
Minor fixes like a loose handle, a worn latch, or a sticking cylinder are often quick. If the lock is broken internally, the locksmith may need to disassemble, clean, realign, or replace components.
Typical time:
- minor repair: 20–45 minutes
- more involved repair: 45–90 minutes or longer
Sometimes repair is not the best option. If the lock is old, corroded, or insecure, replacement can be more practical.
New lock installation
Installing a new lock usually takes longer than repairing one because the locksmith must measure, fit, test, and make sure the lock works smoothly with the door and frame.
Expect around:
- 30–90 minutes for a standard deadbolt or entry lock
- longer if the door needs drilling, patching, or adjustment
If you are upgrading security across the house, allow more time for multiple doors and final key matching.
Smart locks and access systems
Digital and smart locks can be convenient, but they often take longer to install and set up. The locksmith may need to:
- check compatibility with the existing door
- fit batteries or wiring components
- programme user codes or app access
- test emergency override functions
A straightforward smart lock replacement may still be done in under 2 hours, but more complex models can take longer, especially if the door needs modification.
What causes delays on the day?
Even well-planned locksmith work can run over time. Common causes of delay include:
- unknown lock type: the lock differs from the description provided
- missing parts: the locksmith has to source a replacement cylinder, latch, or key blank
- damage: forced-entry damage, broken keys, or a warped door add complexity
- poor fitting: the lock and door have not been installed neatly in the past
- multiple access points: side doors, garages, ranch sliders, gates, and outbuildings all add time
- weather: rain and moisture can swell timber doors, especially in winter
- peak demand: after-hours call-outs, weekends, and holiday periods are often busier
If the job is part of a larger home-improvement project, delays can also happen when other trades are not finished. For example, painters, builders, or door installers may need to finish before the locksmith can finalise hardware.
How to plan around locksmith work
A little planning helps avoid frustration and extra call-out charges.
Before you book
Ask the locksmith:
- how long the job usually takes
- whether the quote includes call-out, labour, parts, and GST
- whether there is a minimum charge or after-hours surcharge
- whether they expect to need special parts
- if you need to be home for the whole visit
If possible, send photos first. That helps the locksmith estimate time more accurately and bring the right gear.
On the day
Make sure:
- someone authorised is present
- keys, access cards, or codes are available if needed
- the area around the door is clear
- pets and children are kept away from the work area
- nearby vehicles or furniture do not block door access
If you are replacing locks after a move, plan to do it before you fully settle in. That reduces the chance of people holding old keys getting access.
If timing matters for your schedule
If you need the locksmith to fit in with other work, build in a buffer. A job that should take 30 minutes can easily stretch to an hour if there is a worn part or alignment issue.
Good times to schedule locksmith work include:
- mid-morning or early afternoon
- weekdays rather than weekend emergencies
- before a tenancy handover or open home
- before painters or builders finish the last stage of a renovation
How locksmith timing compares with other home work
Most locksmith jobs are relatively fast compared with major trades work. You usually do not need a building consent just to rekey or replace standard locks, though more substantial alterations to doors, openings, fire exits, or security systems may have separate requirements depending on the property and the work involved.
For a standard home lock job, the main question is usually not consent but fit, function, and security. That said, if the work is part of a wider renovation, your builder may need to coordinate with the locksmith so the final hardware matches the finished door and frame.
If any electrical wiring is involved, that may fall under electrical regulations and should be handled by the appropriate licensed professional. Similarly, locksmiths are not a substitute for plumbers, gasfitters, or drainlayers on restricted work.
How to get a realistic quote
To avoid surprises, request multiple written quotes where practical, especially for larger jobs or whole-house lock changes.
A useful quote should spell out:
- labour time or fixed price
- call-out fee, if any
- parts and hardware brands
- GST
- after-hours or travel surcharges
- whether the locksmith will return for a second visit if parts are needed
It is also worth checking:
- the locksmith’s experience with your type of lock
- public liability insurance
- any relevant membership, training, or industry credentials
- reviews that mention punctuality and clean workmanship, not just price
In New Zealand, licensing requirements depend on the type of work being done. For standard locksmith services, there is not the same statutory licensing regime as for electrical work, but you should still verify competence and ask questions before you hire.
The bottom line
Most locksmith jobs in New Zealand take minutes to a couple of hours on site, but the total time depends on the lock type, the door condition, the need for parts, and how quickly the locksmith can verify access and authority. Simple rekeying and small repairs are usually fast, while smart lock installations, lockouts with damaged hardware, and multi-door security upgrades can take longer.
The best way to plan is to describe the job clearly, send photos, get a written quote, and allow a time buffer — especially during busy seasons, bad weather, or after-hours call-outs.
