- The call
- The key turns a full circle without any resistance and the deadbolt stays exactly where it is. There is no click, nothing moves behind the face of the lock, and the door is as closed as it was before you touched it.

It is the coldest morning of the winter and the key goes halfway into the side door and stops. There is frost on the face of the cylinder, and the door on the shaded side of the house has done this before.
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.

Seized & Jammed Lock Opening · Innisfil

Scene 1
The first check is the person, not the lock. The locksmith confirms that whoever is asking for the opening is entitled to it, usually with photo identification that matches the address, or a lease, deed, property-management record or a manager who can vouch for you. For a business, a key holder or the person named on the lease is enough. If everything that proves it is behind the jammed door, the check is finished once you are inside and before the locksmith leaves. Then a short walk to the other entrances: a second door on the same key gives a comparison lock and sometimes a gentler way in.
Scene 2
A key that spins freely means the cylinder is fine and the bar behind it, the tailpiece or cam, has broken, slipped or twisted out of engagement. The bolt is then retracted directly through the mechanism rather than through the cylinder, or the cylinder is withdrawn so the locksmith can reach the bolt drive. Once the door is open the old tailpiece is removed and a replacement of the correct length and profile is fitted, since one that is too short repeats the fault and one that is too long binds. The cylinder goes back, the retaining screws are checked, and the bolt is thrown and retracted with the key until it moves cleanly through its full travel.
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.

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.
Possibly, if the key was part of the cause. A worn or bent key lifts the pins short of the shear line, so the plug binds even in a healthy cylinder, and a copy made from that key repeats the wear. A key cut from the code or from a crisp original is the fix. If the lock was also gritty or the door had moved, the new key would have eased things without settling them, which is why the locksmith checks all three.
Occasionally, but wear and weather are far more common. Signs that point to tampering are fresh scratches around the keyway, a plug that sits crooked, or debris such as glue or a broken tool tip inside, none of which appear from ordinary use. The locksmith looks for these during the inspection and says plainly what was found. If the cylinder has been damaged that way, it is replaced and, if you wish, the other doors are rekeyed.
