Smart lock recommendation with physical buttons

Hello,

I live in a very cold climate (Alberta, Canada) and I don’t want to have to take my mittens off to open the door. So smartlocks with touchpads are not an option for me.

I’ve been thinking of getting the Kwikset 620 but I’d like to see if people recommend something else. Also, this will be my first non-wifi device, do I just need to buy a Z-Wave stick to get going?

Thanks in advance!
