Mathematics Problem

[mammutly]

I encountered a similar situation on arriving at a Chamonix apartment block in 2001. It was the early hours of the morning, we were pissed and we had ice axes.

There was no problem

Well, you can examine the keypad very closely. You will see that some of the numbers will be more worn than the others, which means that they are your four digits numbers.

Failing that, and if you have to go for the long way round, I'd do default sequencing then alternative sequencing.

Default sequencing would be to try ones that are defaulted to the safe. 1234, 0000, 1111, 9999, etc.

Failing that, as a last resort, alternative sequencing would have been the quickest way. try 0001 then 1000. 0002 then 2000. Although mathematically, the probabilities are the same, logically, you can start from middle range then move out.

That's how I would have done it anyway, or am I not thinking this through properly?

Once you've opened the safe, its easy to reset the code so worn keys wouldn't have worked.

I did start with the logic you've mentioned but very quickly deduced that the number had changed and had been changed by a human being. Therefore a new approach was needed.

Bolt cutters...?

it was 1234 wasn't it

One thing has struck me.

The booked dates for the property are available on the internet and people with similar codebreaking capabilities could have a free holiday by getting into the safe.

Before anyone asks ...

The answer is *NO*!<br /><br />-- Sun Jun 19, 2011 10:31 pm --<br /><br />

It depends what kind of keypad it is...can you give us that info?

4 digits rotating with numbers 0-9 - 10000 possible combinations - 0000 to 9999.

Alternating turns too?

No.

I would have had a dirty protest, smearing myself and all walls and furniture with shit.

B.S. ? another Thatcher total fuk up ;)
