Customer Reviews

Best key box with one minor problem
This is the only KeySafe that I will buy. However, the newer models are painted with a very dark black-brown finish. Since the numbers for the combination buttons are also painted over, it is very difficult to see the numbers in daylight, and virtually impossible at night.

Very sturdy; only 582 combinations; guess any combination in 65 minutes
This lock feels sturdy. However, as commented elsewhere, the sequence of buttons pressed does not matter. So the combination '12345' is equivalent to '54321' or '23451' , etc.

It takes a 5-digit combination, a 6-digit combination, or a 7-digit combination. Your best security is with a 5-digit combination because there are 252 5-digit combinations. (10 choose 5, mathematically). There are 210 possible 6-digit combinations, and 120 possible 7-digit combinations.

Assuming that the attacker (who's trying to break in) doesn't know how many digits you chose, this means there are 582 possible combinations. If we assume it takes about five (5) seconds to test each one, and you take a 15-second break every minute, then an attacker could find your combination in about 65 minutes. (582 combinations * 5 seconds / 45 seconds of work per minute => 65 minutes). And that's assuming yours is the very-last combination he tries.

(Finally, my Discrete Mathematics class is paying off!)

Good keybox - but small mechanical problem
After more than 2 weeks of slow shipping from amazon, I finally recieved this lockbox. The box works great except the number 1 push button sticks a little. Also, lets say your combination is 1234, you can enter the numbers in any order until you get the right combination. So, you could put in 2413 or 1324, etc and it will open when you get the 4 right numbers. Still satisfied with my purchase, for the most part. Not satisfied about paying $6 shipping via USPS and not getting it for 2 weeks.
