4.0 out of 5 stars
Very sturdy; only 582 combinations; guess any combination in 65 minutes,

This review is from: GE AccessPoint 001406 KeySafe 3-Key Portable Push-Button Key Box, Black (Tools & Home Improvement)
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!)

Best key box with one minor problem,

This review is from: GE AccessPoint 001406 KeySafe 3-Key Portable Push-Button Key Box, Black (Tools & Home Improvement)
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.

Nice outside, cheap plastic inside - BROKE,

This review is from: GE AccessPoint 001406 KeySafe 3-Key Portable Push-Button Key Box, Black (Tools & Home Improvement)
Used this for outside emergency acess for about two months. Worked great until I dropped it once and the plastic "guts" broke into pieces. Took it apart to see if I could realign something to fix it but the 5 numbers I was using as the combo had all broken internally. Bad design by my standards, I would think it should withstand a drop from 3 feet and survive.
