955 SmartCode™ Electronic Pembroke Lever featuring SmartKey Security is a doorknob that really makes me feel a little extra secure. I love the option of getting to enter my home keyless. There have been many times when I am carrying a kid and arm full of groceries. When this happens it is next to impossible to use a key whereas entering a code is so much easier. The keypad is lit up for about 5 seconds at a time so it makes it much more visible. I was very surprised by how easy and quick it was to install. This is powdered by  a single 9 volt battery. One great thing about this is that it isn't just a keypad but also you can use a key. Overall, I feel every household could really benefit from using this.
