The Daily WTF: Curious Perversions in Information Technology

On the type of lockbox you describe, this is actually a simple "x choose y" probability calculation. Imagine putting 10 balls in a bag and choosing 4 at random. This is usually referred to as "10 choose 4" or "10C4". Try entering "10 choose 4" in Google and their calculator will give you the answer, which is 210 possible combinations.

A wrinkle is that with this type of lockbox you can create any size of combination from 1 to 9 digits, as long as the numbers aren't repeated. It turns out that a 5 digit combination is the best (10C5). It results in 252 possible combinations. A 6 digit combination (10C6) results in 210 possible combinations, the same as a 4 digit combination.

they still use them in Southern California, where 99 percent of the population holds a real estate license or is an illegal immigrant ... or both. :)

Actually,new technology has brought electronics to key lock boxes. In particular, Selectlocks.com sells the Model 7060-3 Smart Box from NuSet. It is seriously cool and seriously secure. You can assign a different access code to a lot of users and track their activity.

i remember a spy story: the spy used fingerprint dust to find out which buttons were actually in the code. if it's a 4-digit code, that would narrow it down to 12 possibilities.
