Construction Keying

How often do you hear of security breaches or careless damage during the often lengthy construction phases that have cost the project both time and money?

The Australian Lock Company has offered the building sector BiLock high security locking systems for two decades now. In 1997, we introduced an added feature known as 'construction keying'. This added characteristic was launched in parallel with the patented Quick Change Core (QCC) onto the Australian market!

This facility is available via any one of our accredited agents throughout Australia and selected international markets, and has afforded end users a significantly enhanced ability to maintain a system's security.

Something as simple as colour coding to differentiate the level of access during the construction phase offers the developer or builder a genuine, added dimension when using QCC in security during construction.

  • The door hardware is fitted with the appropriate BiLock Quick Change Core (QCC) cylinder and installed to suit the door/building schedule.
  • The raw construction cores (or plugs, as they are often called) are either keyed alike or keyed to differ in accordance with the builder's requirements.
  • These 'construction' cores are either purchased or rented by the builder to better control security during construction and keep keying costs within budget; no need to install and remove complete hardware or even cylinders with BiLock's colour coded construction keying system.

The Construction cores are fully keyed to 12 pins and your nearest BiLock agent will explain how the system can be designed to suit your specific requirements during construction. The cores are supplied by the agent with keys as required by project management. A QCC control key is supplied to management to facilitate the change of access levels.

3 Tier, Then Handover

It is simply a three tiered system of access using blue, green and red inserts in ALCO's brass construction plug - The blue coloured insert is used during the initial general construction stage of the project through to completion of the shell. For instance, access may be limited to say, plumbers!



By simply removing the core and replacing it with a new core containing the green insert, the developer/builder will then be covered through to lock-up stage and/or finishing trades. For instance, access may be limited to say, electricians and plasterers!


Again, by simply removing the "green" core and replacing with a new core containing the red insert, these locks take the developer/builder through to completion of finished trades and/or through the defects period and on to actual handover to the tenant/owner/s. For instance, access may be limited to say, painters and decorators!

Again, by simply removing the core [or plug] containing the red insert and replacing it with a keyed-up plug [in Chrome Plate, Satin Chrome, Polished Brass or other finish offered by Australian Lock Company].
