Can I use same key for multiple properties

[Al Pat]

I have multiple SFH houses spread within few miles from each other. Besides the houses on the same street, what if I use same key for the properties so I don't have to carry bunch of keys with me? Has anyone did that? Does master key concept work with locks from Defiant and Quaickset? (as some properties have different brands). Tenants dont know each other much less know what properties I have. I am open to other creative ideas.

I use a digital deadbolt from Schlage on everything. Even garages. I set one master code for me, tenants choose their 4 digit code. I go Schlage because they use a 9V vs AAA batteries and when it’s -40*C they still actually work (mainly because use physically slides the bolt) , the AAA’s don’t when it’s that cold.

Really interested in trying the Kevo system soon too though. The gen 2 product looks quite nice.
