Question: Can there be multiable entry code numbers.  If yes, up to how many.
Document: We got this keyless deadbolt because we have many designers in and out of our offices and it was just easier to give them a code than to wait and let them in. The down side is that it cost almost as much as the lock to put in and it's VERY tricky to change the code.
the build quality is cheap, and the combination code mechanism is inherently insecure. example say you set a 5 digit code: 82734ANY combination of those 5 numbers will open the lock. the code setting mechanism has no sense of order. the more digits you specify in the code, the worse the security gets. set an 8 digit code, and almost anyone will be able to open the lock by walking up and randomly mashing numbers.don't buy this lock. it is junk.
I have the electronic more expensive locks on my house. I was looking for a low cost version to Install on my detached garage door. Replaced a standard door knob which made installation easy. Wasn't aware before I bought it that any combination of your numbers will unlock it but for the price you can't beat it.
Changing combination was not hard, nothing flew out of the lock when I opened it as instructed, all went well. Installation straightforward but be aware that your combination can not reuse numbers... if your favorite is 1134 it won't work because of the duplication of the number 1... you need to use 4-6 unique numbers in your combo.
What ever you do, DON'T CHANGE THE COMBINATION! You can (carefully) open it up, but only to find that you are locked in to what order of numbers you can pick, so so much for your favorite order. The fun comes when you try to reassemble, and springs fly everywhere. You reassemble the springs only to have them take off again. It's like Duck Duck Goose only with tiny springs that refuse to stay put.
I installed on my door with no problems. I did have to shorten the "spindle" that comes with the lock and use the shorter screws that are included. One thing I find strange though, it doesn't matter what order you enter your combination in. Say your combination is 12345, you can enter the numbers in any order and it will work. 54321, 32541, 15432, they will all work. An implication of this is that you can't use the same number twice in the combination.
I bought this lock for my entry door to fit over the dead bolt, which is what it was advertised for. I didn't however know that I had to drill an additional hole through the door to receive a long screw on the top of the lock that was attached to the lock on the other side of the door.
This is a very good quality lock, looks good, and saves us many trips to my daughters house to open the door for her.I think for the money it would be hard to find one any better. These folks are a pleasure to deal with and do what it takes to get things correct and ship fast.
In addition, it was tricky to set the new combination since you had to be careful not to lose the pins and springs that could easily come off during the setting of the new combination. Other than that, it looks like a very durable keyless entry lock that doesn't need batteries. I just need to find a way to ensure the drilling of a straight hole through the door. It's been 6 months now and its still sitting in the box.
The code can be changed, but since this is a mechanical lock, it requires the removal of a back plate and moving of little metal tumblers. Be careful when removing the plate, it is spring loaded.
Answer: yes
