Ive had Kwikset locks for years. I love that I can rekey them easily on my own and not have to call someone. They setup very easily, give a decent beep noise when the batteries are running low to keep the keypad operational.
Install isnt hard with them, and if youre having technical issues Ive had to call in once or twice because it was failing when it wasnt and they had very easy instructions over the phone for me to get it fixed.
