This is the second one of these I have owned. I purchased this one because I have used the other for probably close to 10 years and have loved it but decided to put it on my garage when I purchased a new door for my house. It has worked perfectly for what I purchased it has been installed for close to 10 years on my house. This item looks identical to the old one (besides the word "Lockey" added to one side, but there are definite differences and disappointments. Maybe not an issue for some, but for the purpose I am using it for it doesn't work nearly as well. First noticable change.... on the old lock you could change the passcode to whatever 4 numbers you chose. Same function on the new lock...HOWEVER... On the new lock for example if the passcode is 1234... you now push "C" and then "Y" then 1234 to unlock the door. On the "old" lock... you would push "C" then 1234 and then "X" which would unlock the door. On the old lock if you wanted to use the "bypass" function you would hit "C" 1234 "X" and the "Y" key which would put the door on by-pass. Otherwise the lock would automatically lock once it was closed. This new lock can no longer do that. So if I clear the door and open it from the inside it will not lock again unless I hit the "Y" button on the inside of the door. It will automatocally unlock when the lever is opened. While this sounds like a good option in theory the other gave you the option of using by-pass or having the door locked at all times. You never had to worry about it not being locked or forgetting to lock it. You do have the option to disable the "by-pass by removing a tumbler from the "Y" postition but than you can no longer use the "by-pass" function ever. The old way allowed you to easily rotate between using by-pass or locked with just the push of a button. There seems to be no function now for the "X" or "Z" buttons on the lock which seem to now be just additional keys. I am extremely disappointed in the changes with the lock as the other lock has worked perfectly. And the reason I made this purchase. The only reason for replacing it was that I had purchased a new door and loved the lock so much that I plan to put the other on my garage and use this on my house. Also... installing this one seemed much more difficult than the first. Lining up the screw with the rubber plate was difficult and took some finagling. For my purpose I am not sure what I will do...It is beyond the date that I can return it and I love the lock but it's function is not what it was. For the amount of money these cost I would have expected equal quality. Change is not always for the better. I hope it holds up as well as my first one. I live in a 4 season climate and even had weather with -50 below wind chill and it has never failed. The other personal challenge for me is going to be to remember one is maneuvered one way and the other differently.Update** changed my review to **** (4) stars. After using this lock a few times I realized that it is actually easier to open-- instead of the other way-- you simply use the "Y" then "C" button to open without bypass or the "C" then "Y" to set the bypass before the number. Actually much easier to remember just had to retrain my brain a bit. It does make it a little more confusing as I used my old on my garage. Lol So far I haven't had any issues with it and I hope that it holds up as well as my last one which is still going strong on the garage. I would definitely recommend. I live in a climate with all kinds of weather all the way down to -50 below F wind chill. My first one has not failed. I expect this will be the same.Update 4/21: Made it through the winter with no problems. Works as it should. Both locks are working perfectly. I have finally gotten the codes down and have less issue remembering them. Lol I would definitely buy these again.
