I was absolutely amazed at the simplicity of installing this Halo Touchscreen Wi-Fi Enabled Smart Lock. It is very high quality and am very pleased with the design as well as the brushed nickel finish. This uses your WiFi router to pair and the Kwikset App needs to be downloaded on your phone. You can lock and unlock your door this way, or use the keypad, key or turn the deadbolt from the inside to unlock. You can enable access codes for others to enter the home and the App will notify you of any activity and you may view the history. It is patented so the touchscreen prevents on-screen fingerprints and is BHMA certified in security, durability, and finish. Another great feature is that it works with Alexa. I highly recommend the Kwikset Halo Touchscreen WiFi enabled smart lock. It is absolutely wonderful to have peace of mind that our home is secure and easy access to those I provide an access code.
