A proper programmable lock would let you set a temporary password. You could then leave the house wearing just some cheap clothes and get back into your house even if someone stole your clothes while you were swimming in the lake. Sounds good to me. No smartphone. No Internet. No surveillance. There would be a high-entropy emergency password in a sealed envelope hidden in your brother's house in case you ever locked yourself out. But I don't think the market will produce secure programmable locks at a reasonable price until some government regulator lays down a standard that manufacturers can follow.
