Key Safe, are they safe?

alanq

A box claiming to be the only police approved one claims over 4000 key combinations. (actually 4096)

Each key can be used no more than once and the order of entry does not matter.

I'm not sure I agree with what they are saying!

If each key can only be pressed once and the order is not important, the total combinations should be 2508.

792 + (5 out of 12)
924 + (6 out of 12)
792 (7 out of 12)

Thanks for the handy link which I have used for the following.

1 + (0 out of 12)
12 + (1 out of 12)
66 + (2 out of 12)
220 + (3 out of 12)
495 + (4 out of 12)
792 + (5 out of 12)
924 + (6 out of 12)
792 + (7 out of 12)
495 + (8 out of 12)
220 + (9 out of 12)
66 + (10 out of 12)
12 + (11 out of 12)
1 (12 out of 12)
= 4096

Using 5,6 or 7 key combinations is recommended not mandatory.
Using a no key combination is definitely not recommended!

Either type is more secure than putting the key under a mat or a flower pot

Ahh, I missed the bit about 5-7 being recommended.

my old dad use to put the key under the mat outside the back door with a note on the back door saying key under mat :rotfl: that was in the 1970s though.

his best one was leaving the key under the mat and the note on the kitchen table ,... bless him

This may be stating the obvious, but they are only as secure as the wall they are fixed to. So don't fix them in such a fashion as to make it easy for someone to jemmy the whole thing off the wall and then force open the box at their leisure. In most cases this means fixing it to a solid masonry wall.

Mums key safe was fitted today. This was done through her care package with the council. They out source all these sorts of things. I am disgusted at this:mad:

I'd rather try and break in via a window or door than get inside a decent key safe, they are very secure. We have been paid to get into one that failed so carers couldn't get in to see a patient and daughter was in work miles away panicking, and tried to remove one from a property we bought. They are safe enough. If you have secure bars on all your doors and windows, a moat and a drawbridge then the keysafe might be your weakest link.

They are fine, secure and reliable. Just best to site them where they cannot be obviously seen by passers by or casual callers, if possible.
