Until now, I’ve been using an 8-digit combination to set a 4-digit key safe – setting the first 4-digits of the combination directly on the dials, and then adding the second 4-digits to modify the first. The problem is that a sticking dial may sometimes mean I miscount the modifier and incorrectly enter the combination, with unpleasant results. I have now started using a method which looks complex at first, but is all about a methodical approach. Others may find it useful.
 
I request a 12-digit combination for my 4-digit safe, and then scan through it, looking for the numbers 1-4, representing the four dials on my safe. I set the number immediately following that number on the dial. So, for example, if the digit 3 is followed by 7 in the combination, I would set dial 3 to 7.

The following examples show how I set the safe, always ensuring that my thumbs obscure the dials other than the dial I am setting, so I can only ever see the dial I am setting:

Combination 839802780964   
The first of the digits 1-4 is 3, immediately followed by 9, so I set dial 3 to 9.
The next of the digits 1-4 is 2 followed by 7, so I set dial 2 to 7.
The third of the 1-4 digits is 4 at the end, so I continue the series back to the beginning and set dial 4 to 8.
Digit 1 does not appear in the 12-digit number, so I search for overflow digits 5, 6, 7, etc. In this case, there’s no 5 in the combination but I find 6 followed by 4, so I set dial 1 to 4.

Combination 041370042942
Dial 4 is set to 1; (subsequent 4s are ignored)
Dial 1 is set to 3;
Dial 3 is set to 7;
Dial 2 is set to 9 (ignoring subsequent 2)

Combination 966037268789
Dial 3 is set to 7;
Dial 2 is set to 6;
Digit 1 doesn’t appear so I look for 5 (none present) and then 6 and set dial 1 to 6;
Digit 4 doesn’t appear so I look for a second appearance of 6 and set dial 4 to 0.

This seems intricate at first, but I’ve quickly gotten used to it and it seems easier and less prone to errors than my previous system.

I'm intrigued by the chastity eggs on sale recently. Has anyone tried one?

I'm a newbie and exploring things at the moment. Is it possible to view the history of any particular lock, so you can see the changes a bot has made to it?

Also, is it possible to change the default time unit from Days to Hours so that it Fails Safe, rather than Fails Unsafe? Fortunately, I was experimenting when I neglected to change this in the lock setup.
