Securing Detached Garage - Allowing Brief Entries

I’m about to spend a small fortune on an Abode system and all the sensors I need to secure my property. However I can’t figure out how to secure my detached garage.

The situation is that I want it secured during Away and Home modes. However, sometimes when I leave the house I pass by the garage in the alley (after arming the system) and need to pop in to grab something (sports gear etc). My wife does this too, as do other family who swing by to pick up or drop stuff off.

I know I can disable it via the app, but my wife will refuse to do this. It also doesn’t help with other family stopping by.

I thought about keyfobs in the cars, but that doesn’t help with family stopping by.

Is my only option to install another keypad in the garage? I was hoping to avoid this as I already have 3 keypads in the shopping list and I’m trying not to increase the budget much more.

Does Abode understand Zones, like traditional alarm systems? Could I make the garage its own zone?
