Seized & Jammed Lock Opening in Mulhern
The 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.
Seized & Jammed Lock Opening
In plain words
Many jammed locks are not lock problems at all. Wood doors swell in humid weather and shrink in dry winter air, hinges loosen and let the door drop, and a strike plate that was fine in spring is a few millimetres out by autumn. When that happens the bolt is squeezed in its pocket and the key cannot move it. The locksmith checks this first by loading the door in different directions while working the key, and by comparing how the lock behaves with the door open. If the door is the cause, the opening is gentle and the lasting fix is a hinge, strike or seal adjustment.

How the visit goes
Loading the door while the key is worked
With the lock family narrowed, the locksmith puts a hand on the door. Pushing it into the frame, pulling it out, and lifting on the handle each change how a bound bolt sits in its pocket, and the key is tried gently in each position. If the key frees up under one of those loads, the door is the cause. Where a second entrance is open, the same lock family is compared with the door swung wide, since a bolt that throws smoothly in mid-air and binds when closed has been pinched by the frame. Nothing is forced during this test; it is a diagnosis, not an attempt.
Freeing a seized cylinder without forcing it
A plug that will not turn is coaxed, not wrenched. The locksmith flushes the keyway with an electronic contact cleaner to lift out grit and old residue, then applies a penetrating lubricant sparingly, since too much simply carries dirt deeper. The key is worked in small movements, in and out and a few degrees each way, letting the pins settle back into their stacks. If the cylinder cap has loosened, it is snugged so the plug sits square. As the plug begins to move, tension is kept light so nothing inside is bent. Once the door is open, the cylinder is removed for proper cleaning rather than left with lubricant masking the wear.
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
1When the call comes in
An evening, weekend or holiday call for a jammed lock costs the same amount as a weekday one. The locksmith looks at what is actually jammed once on site, and the exact figure follows from that, not from the clock.
2Upgrades you choose on the spot
A keyhole cover, a storm door latch, a reinforced strike or a new deadbolt are optional extras some people add while the locksmith is there, each shown as its own line.
3How many locks are affected
One seized side door is the simplest case; a front and back door that both drag, or a storefront with two leaves, adds hardware and time to the visit.
Seized & Jammed Lock Opening: questions
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.
How do I stop this from happening again?
Three habits cover most of it. Lubricate the cylinder with a dry lock product twice a year and keep oils out of it. Check that the door locks with no pressure on it each spring and fall, snugging hinge and strike screws when it starts to drag. Keep a lock de-icer handy and fit a keyhole cover on exposed doors. And act on the first stiff turn, because a lock that still turns is a smaller job than one that has stopped.
Can an old mortise lock in a century home be serviced rather than replaced?
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.
