I installed this on my front door and now I never have to dig my keys out of my pocket to get in my front door. I added all my family’s fingerprints and made my own 4 digit code incase I have on gloves and don’t want to take off a glove to scan my finger I just punch in the 4 digit code…I like that it comes with 2 real keys also incase the lock batteries die while you’re not home you can still get in with a key. I like that the keypad lights up so you can see what you’re doing in the dark.This product has made life so much easier.It looks good on my front door and it was east to install I’m 100% happy with this lock. So happy I wrote a review and that’s something I never do I never write reviews…but it’s that good.
