How can I install an electronic door lock ? Can an electronic door lock be installed on any door ?

I am fixing to purchase an apartment in Australia and it will come with a "Solid Core door with Deadlocks" for the front door. I just want to make sure I get a secure locking mechanism on my front door (as well as never to remember if I forgot my keys), thats why I am leaning towards the keypad lock things. I am missing HomeDepot

  • They don't have Home Depot in Australia? (Inconceivable!)

Installation instructions depend on the exact model of "electronic door lock" you purchase.

Most of the low-cost/self-contained units install into a standard cylindrical-lock bore (ie, in place of the normal knobset and/or deadbolt), occasionally with another hole or two to anchor them firmly in place. That's an easy retrofit.

Commercial-type units, where the electronics is separate from the door hardware, are more complicated.


It turns out electronic locks (and door passage sets—a.k.a. door handle sets) have a limited range of door thicknesses they install in.

A condo I used to live in had a mondo solid wood entry door 2.5 inches thick (exterior doors are normally 1.75 inches thick). To obtain a suitable electronic lock required a special order, 8 weeks, and $750.

It was a pain to install mostly because the previous mechanical combination lock required custom cutouts in the door which I had to either cover or modify for a standard lock pattern through-holes.

Bottom line: check the actual door thickness and range of the lock. Otherwise, it should fit on "any door".
