Changing Gainsborough main door lock

A-Zed · Jul 06, 2020 9:36 pm

Hi guys,

Tried finding it in the topics but couldnt find it.

Has anyone changed the main door lock themselves before?
My builder is charging me 865$ extra for the Trilock Omni.

If i just get a normal lock, can i install it myself or should i get it done bu builder?

Thanks

Omni's are only about $450-500 and they do take a little longer to install than a standard entrance set.
What sort of lock does your builder install as standard?
The only issue I could think of with retro fitting a Omni after is the size of the holes required to install.
Most standard locks are 60mm backset so all good there.
Standard locks use a 54mm lock hole and a 25mm latch hole.
Omni's use a 60mm lock hole and a 22mm latch. You could make the lock hole work as you actually need to drop the lock hole slightly (and drill a second hole higher) so would need a jig to hold the hole Saw in the right spot as you drill it out. It's the latch hole that maybe just a bit too big to hide it behind the latch plate.
Realistically upgrading to an omni is probably a $500-550 actual upgrade (lock and extra fitting) cost to the builder.
If you get a carpenter to install after it will probably cost you around $650 and you may have a slight gap at the latch.

Our builder (Rawson Homes) charged us $340

The variation wording said:
Provide Gainsborough Omni Entrance Set (Code: 8905 ALL SS) in lieu of standard Trilock to Front Entry Door $340

That would be what I'd expect if you upgrade a trilock to a trilock omni. You are looking at roughly $200-$250 extra for the hardware then a bit extra for fitting and builders margin and $340 sounds right.
If the builder is using basic entrance hardware then it will easily cost you $550-600.
$865 is gouging
