If you find some of the old security cables in your building, you will find
some weirdness with keys for them. Keys were supposed to be left with the
custodians, sometimes also with the head secretary, and the Librarian was
supposed to have keys for their computers' security cables. We tried to
keep using the same number locks in a building but after a couple of years,
we no longer could keep up the same numbers.
Here is the weird part. The key number doesn't always mean a lot. We
removed tumblers from the locks so that a few keys could open most of the
locks. So, if you can't find the correct key number for a security cable,
try whatever keys that you have. Push the cable up into the lock cylinder
while pushing the key into and out of the lock. Often, you can move the
lock out in steps using the "wrong" key. this is what we call in security
"security by obscurity". Most people didn't know that it could be done.
