[This review was collected as part of a promotion.] I have never changed a door knob before, always relied on my dad or brother to help me after I moved into my first home. I needed to change out my lock as an old one had quit working and I got locked out of my house temporarily. I picked this up at our local hardware store today. Only took a short time to install and was super simple! Very easy to set up new code and swap door handle position. Woild definitely recommend to anyone, especially those who may feel like this task could be a bit challenging if it's their first time changing out a lock.
