I installed this lever on the kitchen/garage door. I added it to our ADT security system. We have our alarm to instantly sound when any zone leading to the outside is opened- no delay. We can now disarm the alarm when we unlock the door from inside the garage. It has a setting to lock automatically after 30 seconds. This feature is great if your using it on a door leading to the outside. I set ours through ADT to lock when ADT is armed. I control it through ADT by setting schedules but you can also download the Kwikset App. So far I have nothing bad to say about it. There is about a 3 second delay turning off the alarm when you enter your code to unlock the door. This device can also be controlled with Alexa and a special voice code that only we know.
