I have the schlage but not the kwikset. I agree that the build quality of the schlage is excellent. It seems that relying on the user to turn the deadbolt makes the device that much more reliable. On the flip side, the schlage seems less versatile from the point of view of the uninitiated. If you need to let someone in your house, your aunt for example, then you will need to explain to her how to operate the device beforehand. With the kwikset, you can simply unlock/lock it for her - no need to supply more instructions. Since this will not be a common scenario for me, I’m very happy with the schlage.
I got Home Depot to re-key my schlage to match the other locks in our house. The “SmartKey” feature could be useful if I ever sell the house and it needs to be re-keyed by the buyer. But because the keyless entry means I don’t need to share physical keys with others outside my family, it doesn’t seem to be a big feature for me.
