When the cylinder is the part that has seized, the work is about cleaning rather than force. Keyways collect dust, salt spray, metal filings and residue from sprays never meant for locks, and over time the pins stop lifting cleanly. The locksmith flushes the plug with a contact cleaner, applies a penetrating lubricant, and works the key in small movements until the plug turns. With the door open the cylinder comes out, is stripped and cleaned, gets fresh springs or pins where worn, and is dressed with the lubricant specified for that cylinder. A plug or shell that is worn, damaged or eaten through by corrosion is what gets replaced.

Scene 1
The last questions are about recent history. Has there been a thaw followed by a hard frost, or a stretch of humid days? Is this door on the shaded or windward side, or near a salted driveway? Was the door painted, re-hung, fitted with new weatherstripping or a storm door lately? Has anyone sprayed something into the keyway? Each answer changes the likely cause, and together they tell the locksmith whether this is a one-off, such as a freak freeze, or a lock that is going to keep doing this until the door or the lubrication habit is changed. The answers also shape the advice you leave with.
Scene 2
With access restored, a cylinder that seized gets a proper service. The locksmith removes it from the door, slides the plug out with a follower so the top pins and springs stay put, and lays out the pin stacks. Everything is cleaned, worn bottom pins and tired springs are replaced, and any burr on the plug is dressed. The plug is reassembled to the same combination so your existing keys keep working, then lubricated with the product that cylinder's maker specifies and cycled until it turns with a fingertip. If the key that jammed was worn, a fresh one is cut from the code rather than from that key.
Scene 3
A serviced cylinder stays that way with very little effort. At the interval and with the product that cylinder's maker specifies, a short burst of lock lubricant into the keyway followed by a few turns of the key is enough; stay with that one product, since mixing lubricants makes a paste. Household oils, penetrating sprays and silicone meant for hinges belong nowhere near the pins, because they thicken and attract grit. Wipe the key before it goes in on a muddy or salty day. If the lock ever starts to drag, a puff of lubricant is the first response, and a call is the second.

In most cases, yes. A bolt held by the door is freed by relieving the pressure on the door. A cylinder clogged with grit or ice is cleaned and thawed until it turns. A failed tailpiece is bypassed and replaced. The lock stays on the door with its finish and your existing keys. A plug or shell that is worn, damaged, or eaten through by corrosion or earlier forcing is what has to be replaced, and that is explained before any work starts.
Often, and keeping the original hardware is usually worth trying first, since it fits the door and suits the house, though condition and the availability of matching parts decide whether a repair is realistic. The case comes out of the door edge, the decades of dust and hardened grease are cleaned away, a broken spring or worn hub is replaced with a matching part, and the contact surfaces get fresh grease. If a bit key or a cylinder has worn, a new key is cut or the cylinder rebuilt.
Better not, unless it is a proper dry lock lubricant. Household oils, general penetrating sprays and hinge silicone thicken inside the cylinder and attract grit, so they buy a day and cost a service later. If the lock is frozen, a lock de-icer is fine; boiling water is not, since it refreezes deeper in. The most useful thing to do while waiting is to stop turning the key, so it does not bend or snap.
