for every door

Yes. Those cylinders let an owner change the key with a small learn tool, but only while a working key is in hand. Without one, a design such as Kwikset SmartKey is removed and placed in its own reset fixture, returning it to a blank state; other cylinder types are rekeyed by their own method instead. A new key is then set and the lock goes back on. It is a few extra minutes rather than a replacement.

As many as you ask for, cut on site from the fresh pinning and tested in each door they should open; two or three is typical for a household. More can be cut later. When you do, bring one of the locksmith's originals to be copied rather than a copy of a copy, since every generation strays slightly from the intended depths. If any key is a restricted type, additional copies come from the record kept for that system rather than from a hardware store.

Thousands of turns over the years wear down the small parts inside a cam lock the same way any cylinder wears, and a worn key accelerates it further. A cylinder that spins without engaging the cam usually means the connection between the two has failed, often from corrosion or metal fatigue rather than anything the resident did. Once that connection goes, replacement is simpler than trying to repair the worn parts individually.

Yes, and this is one of the more useful parts of the system. A front office can unlock for regular business hours, a stockroom can allow only two credentials at any hour, and a loading dock can release only during a set delivery window. Schedules are set per door and per access level in the controller, and can be changed at any time without touching the hardware itself.
