Total Control Over Access

Restricted key systems aren’t just for large organisations—they’re an excellent fit for any property where multiple people have access. Unlike standard keys, which can be easily duplicated at hardware stores, restricted keys can only be cut by the original locksmith and only with written authorisation. That means you always know exactly how many keys exist—and who holds them. At Eastcoast Locksmiths, we tailor every system to suit your setup, from single-door installs to multi-level master key systems. We use high-quality, durable lock components and secure key profiles registered to our business, giving you legal protection and long-term security. And if you need to expand or reconfigure the system later, we make it easy.


  • Custom systems designed for your property
  • Registered profiles and complete key control
  • Scalable solutions for growing needs


Are you looking to upgrade your access system or tighten control at your property? Restricted key systems are one of the most effective ways to do it. For advice or a tailored solution in Port Macquarie, call (02) 6583 3256 today.

Frequently Asked Questions

  • What is a restricted key system and how does it work?

    A restricted key system is a lock and key setup where the keys cannot be copied without authorised permission. These keys use a patented design and are linked to a specific locksmith or locksmith business that holds the legal rights to cut them. This means keyholders can’t simply go to a hardware store to get a duplicate made. These systems are ideal for properties that require tight control over who has access, such as offices, apartment buildings, schools, or any location with shared entry points.

  • Who should consider installing a restricted key system?

    Restricted key systems are highly recommended for businesses, landlords, real estate agencies, strata managers, schools, medical clinics, and even residential properties where access needs to be controlled. They help reduce the risk of former tenants, employees, or unauthorised individuals having duplicate keys. These systems also provide a clear paper trail and accountability for who has access to what areas.

  • Can I add new locks or keys to an existing restricted key system?

    Yes, most restricted key systems can be expanded or reconfigured as needed. If you want to add more locks, restrict certain keys to specific areas, or issue additional keys, your locksmith can modify the system accordingly. You’ll need to go through the same authorisation process to add or duplicate keys, which keeps the system’s integrity intact. This flexibility makes restricted key systems great for growing businesses or evolving property needs.
