Restricted key systems Hobart
Commercial restricted key systems installed by Master Locksmiths
When you run a site with staff, contractors or tenants, loose keys can turn into big problems. Tasmanian Mobile Locksmith sets up restricted key systems that make sure every key is registered, trackable and impossible to copy without approval.



Restricted key systems for businesses that can’t afford mistakes
Tasmanian Mobile Locksmith has fitted restricted key systems across offices, depots, schools and government buildings all over Hobart. Every lock and key is registered through the Master Locksmiths Association, so no one can make a copy without your say-so. When keys go missing or staff move on, we can rekey, audit or expand your system on-site without slowing your operations.
- We map access levels room by room, so site managers, cleaners and contractors only reach the areas they’re approved for.
- Each key is stamped, numbered and logged in our secure MLAA database, so you’ll always know exactly how many exist and who has them.
- We rekey and issue replacements on-site when staff change or tenants move out, keeping your security tight without interrupting daily work.

Every restricted key system service is handled by master locksmiths
We’ve spent decades fitting, testing and maintaining key systems for Hobart’s busiest sites. From the first cylinder cut to the last audit check, every step is done by hand and logged for accountability.
Custom system design for complex sites
No two sites run the same. We walk the property, talk to your managers, and map how people actually move through the space. Then we build a key plan that matches real workflows, from front reception to fenced compounds, using MLAA-registered keyways that cannot be copied without written approval.
Professional rekeying and secure key replacement
When staff move on or a contractor loses a key, we do more than swap barrels. We review your whole access structure, re-pin affected locks, and issue fresh keys under the same restricted profile. The old keys stop working immediately, and your audit trail stays clean.
Scheduled maintenance and security audits
Every few years, commercial hardware starts to show its age, especially around salt air and heavy foot traffic. We service hinges, lubricate internal components, and run full key audits to catch inconsistencies before they become risks. You receive a clear report showing every key issued and every lock still in service.

Insights from decades on the tools
Real lessons from years of fitting, servicing and fixing restricted key systems across Hobart’s offices, depots and government sites.
The weakest link isn’t the key, it’s the paperwork
We’ve seen perfect systems fall apart because no one kept the register up to date. Keys walk off, staff move on, and suddenly no one knows who has access. A good system is only as strong as the list that tracks it. We help clients keep that list clean, current and simple to manage.
Cheap door hardware ruins good security
We’ve fitted brilliant restricted systems onto doors held by soft screws or budget hinges. It’s like locking a screen door in a cyclone. The keyway might be bulletproof, but if the door flexes or the strike plate bends, the whole plan fails. Good hardware is part of good security.
Overcomplicating access creates chaos
Managers love long key hierarchies, but the more levels you add, the more chances there are for confusion. We design systems that keep control without turning daily access into a puzzle. Clear structure, clear rules, fewer headaches.
Salt air doesn’t care about stainless labels
Near the waterfront, salt gets into everything — hinges, springs, even cylinders marked as marine grade. We’ve pulled apart locks that looked fine outside but were frozen solid inside. That’s why we choose proven materials and schedule maintenance before things seize.
A review every few years keeps the system honest
Even the best setups drift out of sync as people come and go. Old keys turn up in drawers, contractors keep spares, and locks wear just enough to lose tolerance. A periodic rekey or audit resets everything and stops small gaps from becoming security holes.
The best security comes from communication, not technology
We’ve seen simple systems outperform fancy ones because managers stayed in touch with their locksmith. A quick chat about who has left the business or which doors stick in winter often prevents bigger problems later. Good security starts with good habits.
The story behind Tasmanian Mobile Locksmith
Most mornings start the same way — a quick coffee, the van door sliding shut, and the sound of tools shifting on the road out of town. That’s how Rob’s been starting his days since 1989, when he decided to make a go of locksmithing on his own. The tools are newer now, and the fleet’s a bit bigger, but the approach hasn’t changed: do the job properly, treat people right, and leave every site safer than you found it.
- We’ve worked everywhere from ferry terminals to farm sheds, often in weather that makes keys freeze in your hand.
- Our team includes tradespeople who’ve been with us for decades and still take pride in doing things the careful way.
- We’re still family-run, still local, and still happiest when a job ends with a firm handshake and a working lock.

Questions about restricted key systems
These are the questions we hear most often from local businesses and site managers. Every answer has been checked by our locksmiths to make sure it’s accurate, practical and worth your time.
How does a restricted key system actually work for a business like mine?
A restricted key system provides tight control over who can open what. Each key is cut from registered key blanks that can’t be copied at a hardware shop, so you know exactly how many exist and who has them.
We register every key under a patented profile that only authorised locksmiths can cut. That registration creates a paper trail; every key ordered is logged, signed off, and recorded against your business. If someone tries to make a copy without approval, it simply can’t happen.
After thirty-odd years fitting these systems across Hobart, we’ve learned the key isn’t just the metal, it’s the record keeping. We’ve walked into factories with missing registers and found twenty extra keys no one remembered approving. That’s why we help clients keep their lists current, a good system works best when it’s looked after.
What’s the difference between restricted and master key systems?
A restricted system stops unauthorised key cutting. A master key system decides who can open which doors. Together, they give you both control and convenience, the right people in the right places, and no one else.
In a standard setup, an individual key opens one door while a single key or a grand master unlocks everything in the building. The structure is designed so maintenance staff, managers and contractors all have access to what they need without tripping over each other.
After decades of building these systems for schools, warehouses and government sites, we’ve learned that the simpler the hierarchy, the better. We’ve seen setups with five layers of control that left everyone confused. Clear access levels make for stronger, safer systems and far fewer lost keys.
Can you add new doors or areas to an existing restricted key system?
Yes, we can. A well-designed key system to suit your site can be expanded at any time, whether you’re adding new buildings or separating access for multiple sites.
We work with commercial buildings and stratum properties across Hobart, extending existing systems or creating new tiers of access as businesses grow. Because the locks are modular, we can re-pin or rekey them on-site with minimal disruption.
If you’re updating your layout or expanding to new premises, upgraded security key systems are available that match your existing keys. We’ll design a structure that scales with you, keeping everything consistent and compliant.
How do I know who’s authorised to get extra keys cut?
Under a restricted system, only an authorised person listed on your key register can request a duplicate. This prevents anyone else from trying to make copies or bypassing your control process.
Each business nominates a custodian who oversees key distribution. When someone needs another key, the locksmith verifies their details before cutting it. That simple step ensures traceability and protects your liability.
We also help clients set up approval protocols so only the right people can act on behalf of the company. It’s a straightforward way to ensure key security stays tight without adding red tape.
What happens if an employee loses a restricted key?
If a restricted key goes missing, don’t panic. Because of the system’s high security design, no one can cut a replacement without approval. Still, you’ll want to act quickly to maintain maximum security.
We can re-pin or replace the affected lock cylinders to make sure the lost key no longer works. This prevents anyone from using it without authorisation and restores full control.
It’s a confidential process handled on-site, and it’s one of the biggest reasons businesses choose restricted systems. You get peace of mind knowing a lost key doesn’t mean a full lock replacement or a major security risk.
How often should a restricted key system be reviewed or audited?
A well-run site should review its key management at least once a year. That quick check keeps your access list accurate and your system compliant with insurance and audit requirements.
We’ve done countless audits where we’ve found keys still in circulation years after the holder left. It’s not bad intent; people just forget. A simple review keeps your registers clean and your security tight without needing major rework.
Our specialist locksmiths handle full-site audits, checking every lock, key and record against your register. We often find one or two surprises hiding in drawers, but catching them early is what keeps the whole system sound.
Are restricted key systems weatherproof enough for Hobart’s conditions?
Yes, when they’re built properly. We use robust hardware and proven broach designs that stand up to Tasmania’s sea air and temperature swings.
Around industrial property, locks take a beating from salt and wind. We specify products that have been field-tested locally, including models designed for restricted areas and high-traffic sites.
Restricted key systems are ideal for environments that need defence against corrosion and intrusion. Each lock we install is tested to maintain access to certain areas even under harsh southern conditions.
Can you integrate restricted keys with digital or electronic access systems?
Yes, we can combine both. Modern access control solutions let you manage staff movement electronically while keeping restricted keys for mechanical backup. It’s a balanced way to cover every access point.
We design hybrid systems for multiple departments or locations that need different levels of control. Keys can secure safes, storerooms and utility areas, while fobs or cards handle high-traffic entries.
Our setups work for residential applications, offices and large commercial sites alike. Each system blends high security hardware with reliable key and lock operation, giving you flexibility without losing control.
