Our keyless is a deadbolt. The knob is just the original keyed version that you can lock from the inside by pushing the button but, of course, we leave the knob unlocked or that defeats the purpose of the keyless deadbolt.
I also like that we can program additional codes for the keyless. Whenever we have guests, we program the last four digits of one of their phones as the access code so we don’t have to give out our primary code, and we erase the temporary code when the guests leave. We can also remotely open/lock the doors which has come in handy when we’ve been at one place and needed to allow entry for someone at the other.
