St Kilda homes are not one thing
Within a few streets you will find Victorian terraces with original joinery, interwar walk-up flats, 1970s brick units, renovated townhouses and new apartments with commercial-grade entry hardware. Each locks up differently.
Older timber doors need work that respects the door as much as the lock. Aluminium sliders need the right hardware for the section. Newer apartments often involve building entrances, common-property rules and an owners corporation. Knowing which you are dealing with is most of the job.
