Took myself maybe twenty minutes to install on the door. And then it to me oh. About an hour to think of a code I liked. Lol. It was a walk in the park. Everything is solid not flimsy at all. Heavy solid slide dead bolt. I’m like the extra opportunity for the back lit numbers. Very nice. And the price was good too. Now I can go do yard work or anything else without my keys constantly in my pocket.

EASY TO REPLACE YOUR DEADBOLT AND HAVE THE WONDERFUL ABILITY TO TRAVEL WITHOUT A KEY TO GET IN AND OUT. YOU CODE IT AND YOU ARE HOME FREE. WAS EASY TO INSTALL (REPLACED A DEAD BOLT) AND WITHIN MINUTES ENJOYED THE FREEDOM OF HAVING TO HAVE A KEY. KEEP A SPARE KEY HIDDEN FOR THOSE TIMES THAT POSSIBLY YOUR BATTERIES RUN WAY TOO LOW OVER A LONG TIME (MOST EVERYTHING HAS A MAINTENANCE SCHEDULE, NO DIFFERENCE HERE).

The media could not be loaded. Installed myself in 5 minutes!!! So easy, I want do more doors now!

Very easy to install, lock and unlock. Like fact that an individual number can be assigned to users.

This was such an easy install! It has saved me on making trips when my son forgets his keys! It didn’t take too long to install and it matched perfectly with my door knob!

This is not a “smart” lock. I knew that right up front. Having said that it works exactly as it was intended. My husband installed it within 15 minutes or so. We have several lock combinations saved so if we have to give one out to somebody we can. Then we can delete that particular combination and make another one. I love the ease with which this works. When you leave just close the door firmly and push the lock button. To unlock, simply punch in your code and then push the unlock symbol. That’s it. There is one button which provides a light when you push it and it makes all the number keys light up. We love it! Now that I know I like an electronic deadbolt, the next when I purchase will probably be a “smart“ lock so I can control it with my Amazon Alexa device.

Am a "Senior Citizen." Always lock the front door when home. Bought this so that, if I ever have to call 911 for help, I can give them the "lock code" and they won't have to break the door down! Could save precious minutes. This lock was easy to install and program (follow the instructions...there are two important "cautions" in them.) Has worked without any problems for almost two months on one set of batteries. (Caveat: I recommend that you always take a key with you. If the batteries fail, you will not be able to get back in.) The keypad's "one button lock" and "night light" features are great.

Very convenient. So glad I stared using this!

Lock is fantastically priced and works great,no more lost keys with the 13 year old. The negative reviews I have read seem to be install issues,if the lock is very tight it would be an alignment problem,understand that electronics can be defective but the customer service responds right away.As this is a mechanical unit that operates on its own and not manually with a key being turned it is imperative that it is lined up to perfection to allow the unit to operate as it is intended and mine does,it's not Rocket Science to install but it does take some degree of mechanical ability to install properly. One simple solution to install correctly is to read the simple instructions and if they don't make simple sense to you,you may be in over your head, get a friend with some mechanical ability to give you 15 minutes of his time to do it,as my door was already drilled correctly literally took me 7-8 minutes to install,has already withstood the test of time as the girl and her friends love playing with it,switching codes,locking each other out,cheap way for her mom to entertain them. Highly recommend this unit.

It fit easily into a pre-drilled security screen door. I live in a rental so I'm not allowed to have locks that don't match the front and back doors. But for a temporary solution this was fabulous and I'll be using it again. It's super strong considering it only runs on four AA batteries
