I have Kwikset KW-1 5pin locks (At least 10 of them). Since I have a duplex, I'd like to make two keys and have three locks (Unit 1, Unit 2, and Common)
So that each tenant can have a single key which opens the front/rear/garage door and their unit, but not the other unit.
Is this possible? What would the pin patterns need to look like?
I want each tenant to hold a single key (they currently carry two). That key should open the front door (which is shared) and their unit which has no exterior door.
Which to me says there should be two patterns for keys (each unit)
And three patterns for locks:
- Shared, that can be opened by either key
- Unit 1, that can only be opened by key 1
- Unit 2, that can only be opened by key 2
Been reading a bit about master pins. Maybe the right answer is put the same change key on the front door and unit one, and just use the master myself. Then I can open all doors with one key, and they can open just common and unit one. Obviously that won't work in a few years when we move on and rent both out though.
