As far as I'm aware, the Keys are permanent, or at least I didn't see any timers on them, not that it should matter since there's no point keeping them in your inventory.

As for the Docks themselves, well, I've had mine for half a year or so and haven't had to repurchase them, I think it's safe to assume they're permanent.
