Chastity During Time Apart

There is a good chance that my wife and keyholder might be taking a job out-of-state. I’m curious how you all manage being locked up while your key holder isn’t nearby. Previously, I coped with this by masturbating frequently and watching porn. This time around, though, I feel like having an emergency key hidden away somewhere would be nice in case of need. I haven’t brought it up with my wife yet, so I’m unsure how she’d react. Traveling to see her about once a month should be feasible for me. Up until now, although locked, she has been nearby and could release me whenever she chose, which both thrills and frightens me at the thought of her being in another state while I stay home locked up. Has anyone else here experienced this before? What setup did you choose? How well does it work?
