They are close relatives. A key that will not come out is usually a plug that has not returned to its neutral position with the shell, a cylinder cap that has loosened, debris in the keyway, or a cylinder that is pinned incorrectly; some cylinders are also designed to hold the key until the plug is returned. The locksmith frees the key first, without pulling, then treats the cause the same way as any seized cylinder.

Plan on an hour or two for a typical house with three or four cylinders, including the walk-through, identification, pinning, cutting and testing. Each additional cylinder adds a little, as does swapping a cylinder to bring a mismatched door onto the same key, resetting a homeowner-rekeyable lock or clearing a garage opener. The locksmith gives a realistic window on the phone once the list of doors is known.

It does, with one check: the thumb-turn and the outside cylinder have to clear the storm door when it closes. Most storm doors leave enough depth, but a low-profile deadbolt trim is chosen where the gap is tight. The storm door's own latch is separate and does not replace a bolt on the main door, since a screen frame gives little resistance on its own.

You generally do not need to; identifying the hardware is part of the visit. The locksmith reads the maker's mark on the lock face, measures the cylinder and cam, and checks the hole pattern in the compartment door, which together point to a matching replacement even when the original brand is no longer sold.

The mechanical resistance of the cylinder does not change, but blanks may become openly available, so copy control weakens. Manufacturers issue new patented keyways as older ones expire, and the usual answer is to move to the next generation by changing cylinders and keys while keeping the lock bodies. Your locksmith notes the patent term at handover so the date is on the calendar rather than a surprise years later.
