How can I unlock the door to my house remotely?

Episode 1225 (1:15:51)

Chip from Philadelphia, PA

Chip would like to have a door device that will unlock his door via the internet. Leo says that Schlage, Kwikset, and Yale make locks that would allow him to unlock his door via smartphone. Kwikset also makes a code for giving to technicians that will only work within a set time window. But he'll have to be careful of the NFC features that unlock the door when he would walk up because it sees his phone.
