Are you looking for an alternative way to get into your home without fumbling about with a set of keys? Perhaps the Kwikset SmartCode Signature Series might come in handy – this keyless entry deadbolt comes with a touchpad that will open up the door whenever you key in the right access code. You can have a unique set for yourself, while visitors can have another for temporary access. Perfect for those who have to pick out the right key after a late night out, but on the downside, you’ll have yet another number combination to remember. A quartet of AA batteries power the Kwikset SmartCode Signature Series, and it is said to last for up to a year.
