For me one key is in my locker at work... I use this for hygiene openings etc but it stays at work and I don't regard it as an escape route.
"My" key is in a lockbox at home. Who has the combination to the lockbox depends on the situation... sometimes me, sometimes not.
And finally I have an emergency key at my best friend's house, but if I ask for that one there are consequences.
So even though I take my belt off for work some days, I still regard the one in the lockbox as the only way to get a release.
