I would discourage having the Kwikset deadbolt disarm your alarm, unless Kwikset changed their lock significantly since I got mine. Ultimately you are placing a lot of trust in a device that is 1 couple of buttons away from anyone setting their own code. The problem with the Kwikset is you just have to slide open the cover, hit the button to learn a new code…key in a code and its accepted. No security, meaning a door-to-door solicitor that you invite in, a guest, or anyone could do this pretty quickly if your back is turned even for a few seconds…and its an easy lock to identify from the outside. So now you ultimately allowed someone to self program their own access to disarm your alarm.
I have one of these locks, but it still requires the alarm to be disarmed independently due to this design flaw. There are other brands that require a master code to add new codes.
