Locksmith work in apartment buildings and body corporate complexes is a little more involved than a standard house call. Because multiple parties share ownership and access responsibilities, a locksmith needs to be clear on who has the authority to approve the job, what systems are already in place, and how any changes will affect other residents or building managers.
Who Has Authority to Approve the Work?
This is the first question any good locksmith will ask. In a body corporate building, the body corporate (the collective of unit owners, usually managed by a body corporate manager) typically controls common areas — entrances, lobbies, car parks, stairwells, and shared facilities. Individual unit owners or tenants control their own unit doors.
In practice, this means:
- Common area locks (main entrance, letterbox banks, car park gates): Changes usually require approval from the body corporate committee or manager.
- Unit entry doors: The unit owner can generally authorise work on their own door, but any changes must not compromise the building's master key system if one exists.
- Tenanted units: If the unit is rented out, the landlord (unit owner) is typically the authorising party, not the tenant — though tenants have rights around access under the Residential Tenancies Act. Check Tenancy Services for guidance on landlord and tenant obligations.
A locksmith will ask for proof of authority before starting work, especially for common area jobs. This protects everyone involved.
Master Key Systems in Apartment Buildings
Many apartment buildings use a master key system — a hierarchy of keys where a grand master or building master key opens every lock, while individual keys only open specific doors. These systems are carefully designed and registered with the lock manufacturer or supplier.
Working within an existing master key system requires:
- Identifying the system: The locksmith needs to know the brand, series, and key profile in use. Common systems in NZ include Abloy, Mul-T-Lock, Lockwood, and Assa Abloy products.
- Ordering keyed-alike or keyed-to-master cylinders: Replacement cylinders must be ordered to match the existing hierarchy. This can take time if the system is a restricted (patented) key profile.
- Restricted key profiles: Many body corporate buildings use restricted key profiles, meaning keys can only be cut by authorised locksmiths who hold the relevant licence for that system. This prevents unauthorised key copying — an important security feature.
If a locksmith is not registered with the relevant key system, they may not be able to supply matching cylinders and will need to refer the job to a locksmith who is.
Emergency Lockouts in Apartments
Lockouts are one of the most common callouts in apartment buildings. The process depends on the situation:
- Locked out of your own unit: The locksmith will verify your identity and right to access before picking or bypassing the lock. Expect to show ID and, in some cases, proof of tenancy or ownership.
- Building entrance lockout: If you're locked out of the main building entrance (e.g., your fob or swipe card has failed), the locksmith may need to contact the building manager or body corporate to authorise access or issue a replacement credential.
- After-hours emergencies: Many body corporate buildings have an after-hours contact number for the building manager. It's worth trying this first, as they may be able to remotely unlock electronic access systems without a callout fee.
Electronic Access Control Systems
Modern apartment buildings increasingly use electronic access control — swipe cards, key fobs, PIN pads, or smartphone-based entry. These systems are usually managed centrally by the body corporate or building manager.
A locksmith working on these systems needs to understand:
- Who administers the system: Adding or removing credentials (cards, fobs, PINs) is usually done by the building manager through software, not by a locksmith with physical tools.
- Hardware faults: If a reader, electric strike, or magnetic lock fails, a locksmith with access control experience can diagnose and replace the hardware component.
- Integration with fire systems: Electric locks in common areas must fail-safe (unlock) in a fire alarm event, in line with the NZ Building Code. Any modifications to these systems need to be done carefully and may require building consent depending on the scope of work — always check with your local council.
Rekeying vs. Replacing Locks
| Option | Best For | Considerations |
|---|---|---|
| Rekeying | Lost keys, change of tenancy | Cheaper; must match master key system |
| Cylinder replacement | Worn or damaged lock | Must be compatible with existing hardware |
| Full lock replacement | Upgrading security | May need body corporate approval for common doors |
| Electronic upgrade | Building-wide access control | Significant cost; body corporate decision |
Building Consent and Compliance
Most standard locksmith work — rekeying, cylinder replacement, fitting a deadbolt to a unit door — falls under Schedule 1 exemptions of the Building Act and does not require a building consent. However, structural changes, new door frames, or modifications to fire-rated doors or electronic egress systems may require consent. Always confirm with your local council if you're unsure. MBIE Building Performance has useful guidance on what requires consent.
When to Call a Professional
Always use a qualified, experienced locksmith for body corporate work. The stakes are higher than a standard house — a mistake can affect the security of every resident in the building. Look for a locksmith who:
- Has experience with master key systems and access control
- Is registered with the relevant restricted key system suppliers
- Can liaise professionally with body corporate managers
- Carries appropriate insurance

Safety note: Never attempt to force or bypass a lock in a common area yourself — this can cause expensive damage and may raise security concerns with other residents or building management.
