This could have been a great product, but it really missed the mark. We had a similar keypad on our door prior to purchasing this that worked good, but we wanted an upgrade. Unfortunately, this was not what we expected. They sent the wrong screws which were way too small. My husband had to go to the hardware store to get screws that would work. Then the directions were a nightmare once it came time to get the code, etc set up. The QR code that you scan on the instructions didn’t take you to the correct place and there were no clear instructions on how to complete the functions to actually get the lock and unlock functions to work with your code. After hours of trying, we were finally able to find a short YouTube video that showed us the administrator code of 123456 and then we could enter our preferred code. We still have to figure out how to get the fingerprints, etc to work, but after that struggle, I have no desire anytime soon to work any further on this. At least we can lock and unlock our door with a code.

The installation was kind of challenging. First of all, if you have door that are cover in metal, the hole for the lock will be too small. Second, the screws are not 2.5, they are 2 38 so they will be too short. We had to change couple things to make it work. Overall, the quality of the lock is good. It’s an easy solution if you forget the key, the code is very helpful.

The Dalton Z07 was a big disappointment. It arrived quickly but was downhill after that. The piece had wrong parts. Screws didn’t work and it was such poor quality parts broke. It took my husband many hours trying to make it work but it will actually go in the garbage once we get a new door. Would not recommend.
