A shrouded shackle and a drainage-friendly body cope with rain and salt far better than an indoor lock left outside.

Every square is one home in a hundred.
Often, yes. A replacement cylinder in the same keyway can be pinned to the cuts on the key already on your ring, so the front and back doors stay on one key and nothing else in the house changes. If the old keyway is no longer made or the key is badly worn, the new cylinder comes with fresh keys and the other doors can be rekeyed to match in the same visit.
Yes, at every cylinder that was rekeyed. Once the bottom pins are changed, a key cut to the old combination lifts them to the wrong heights and the plug will not turn. The locksmith proves this at each door by trying the old key after the new one, because any door missed from the list would still answer to the old key. That is also why the walk around the property at the start matters: every door meant to be included has to be on the list.
You can, with a conversation first. Tenancy rules in this province expect a tenant to have the landlord's consent before changing locks and expect the landlord to hold a key, so ask in writing and share the plan. Many landlords welcome a proper bolt. The locksmith can key the new cylinder to the building's existing key where the keyway allows, and leave a note of the model and keys cut for the building manager.
Choosing corrosion-resistant fasteners and a cylinder rated for weather exposure at the outset avoids most of the problem, since plain steel fittings near a driveway or walkway take the brunt of de-icing salt over a winter. For hardware that already shows early corrosion, cleaning and a dry lubricant can extend its working life, while pitted or seized parts are better replaced than fought with season after season. A rinse of the hardware after a heavy salt application is a simple habit that helps as well.
