Seized & Jammed Lock Opening
The old mortise lock on the front door of the house turns the key halfway and stops with a dull clunk. It has been getting harder for months, and the brass key is starting to show a bend.
Seized & Jammed Lock Opening
In plain words
This service has a season here. The first wet fortnight of winter sends meltwater into keyways that freezes overnight, and doors on the north and shaded sides of a building stay iced the longest. Salt spray from driveways and walkways leaves a crust that thickens with every thaw. Then summer humidity swells wood doors until the bolt drags in its pocket. A jammed lock opening in these conditions means thawing without boiling water, flushing out salt, drying the cylinder, and dressing it with a lubricant that sheds moisture, along with a check of the door so the same weather does not jam it again next month.
How the visit goesThe key slides all the way in, exactly as it has for years, and then refuses to turn in either direction. Yesterday it needed a small wiggle. This morning it feels set in concrete, and pushing harder only makes the key flex.

How the visit goes
What the weather and the house have been doing
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.
Taking the load off a bound bolt
When the door is the cause, the opening is a matter of leverage rather than tools. The locksmith lifts, pushes or pulls the door to bring the bolt back into line with its pocket while the key turns, and the bolt slides home. With the door open, the reason is dealt with: hinge screws tightened or replaced with longer ones that reach the framing, a hinge shimmed to raise a dropped door, the strike plate moved or its edge dressed with a file, the bolt pocket deepened with a sharp chisel, or a weatherstrip trimmed. The lock is then thrown and retracted with the door closed until it moves without any pressure on the door.
Keys that match the lock again
Where a worn or drifted key was part of the jam, you now hold a key cut from the code or from a fresh master, and every spare has been tried in the lock. Retire copies that needed force, and cut future spares from the good key rather than from each other, since each generation of copying adds error. Label the keys if several locks are involved. If the cylinder was replaced and pinned to your existing key, the whole house is still on one key. Keeping a written note of the keyway and, where it exists, the key code makes any future key a simple cut.

What affects the quote
Same fees day, night or weekend
1The drive to you
Driving time is part of every call, and a property at the end of a long rural road is a different trip from one a few streets over.
2Inside door or outside door
A jammed bedroom or office privacy lock is generally a lighter job than a weather-exposed exterior deadbolt, and a mortise lock on an interior door sits between the two.
3Cutting fresh keys
If a worn key was part of the trouble, keys cut from the code or a fresh master are counted individually, so say how many the household or staff need.
Seized & Jammed Lock Opening: questions
What lubricant should I use afterwards, and how often?
Whatever lubricant and interval the cylinder's manufacturer specifies, applied with a few turns of the key. Stay with that one product, because mixing different lubricants can make a paste. Oil, hinge silicone and general-purpose penetrating sprays are kept out of the keyway. Lock manufacturers describe cleaning the cylinder with an electronic contact cleaner before lubricating, and that is the order the locksmith follows on a service too.
The thumb-turn is stuck from inside and we need that door to get out. What should we do?
Use another exit for now and call. From the inside the fault is usually a bolt pinned by the frame or a bent spindle, both of which the locksmith frees without damage. A main exit door should open from inside without a key or special knowledge, so the repair leaves the door doing exactly that, and if the hardware on it was the wrong type for an exit, a thumb-turn deadbolt is suggested.
Should I spray something into the keyway while I wait?
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.
