Recently had one of those Careline things installed for an elderly
relative so she can get help if she has a fall by pressing a
button on a pendant. One of the options given was to install a
key safe outside the house so that staff can gain access in an
emergency. This seems eminently sensible.

They fit it at the rear of the house

I hope not!
They aren't that difficult to open by going through the combination
and fitting it at the rear out if sight gives the crook as much
time as he needs.

Dennis, if you use 4 digits there are 10,000 possible combinations.
The GE
keysafes can use up to 6 digits. It would take days to go through
them.


The GE Slimline KeySafe can use up to 7 digits, giving 10 million
possible combinations. You could spend your whole retirement trying
to find the combination. ;-)


The GE can have each button pressed once only, pressing it more than
once has zero effect.
There are 1023 + 0000 combinations no matter how many digits you
select as long as you don't tell the cracker how many digits he needs
to press.
F-, join TMW in the dunces corner.

Not so. The most common code set is year of birth. If an ambulance crew
don't know the code, they ask a neighbour how old the patient is & key in
the year. It works 90% of the time.

You couldn't have 1941, 1944, 1949 etc if you could only use each button
once.
