- 24hr Emergency Locksmith Available Now
Strata · Commercial · Industrial
Perth’s proven security authority for strata and commercial properties. For over 46 years, Diamond Locksmiths has worked with strata managers, property managers and business owners to deliver structured, reliable security systems.
Restricted key systems give you complete control over who can access your property. Unlike standard keys that can be copied at any hardware store, restricted keys can only be duplicated by authorised agents with written permission.
Keys only issued to authorised parties — no unauthorised copies possible.
All key issuance tracked with advanced key management software.
Easily expandable as your property or portfolio grows.
Documented audit trail for strata compliance and insurance requirements.
Most strata properties are still using standard key systems that can be copied without authorisation. A restricted key system upgrade is one of the most cost-effective security improvements a property manager can make.
We understand that property managers and facility managers need more than just a tradesperson — they need a reliable security partner who can manage the entire process. Diamond handles quoting, scheduling, tenant communication, on-site work, invoicing and compliance documentation so you don’t have to.
“We place ourselves in your shoes — ensuring your property is secure, compliant and protected at every level. That’s not just a service, it’s a commitment.”
Fast response · No obligation · Trusted Perth locals

Had Diamond install a full restricted master key system across our 32-unit complex. The project was delivered on time, on budget, and the team were professional throughout.

Sam came out and did a full security audit of our commercial premises. Clear recommendations, fair pricing, and the work was completed exactly as agreed. Couldn’t be happier.
