Seized & Jammed Lock Opening in Lafontaine

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.

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.

Sound familiar?

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.

  1. 1

    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.

  2. 2

    Stripping and rebuilding the cylinder on the bench

    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.

  3. 3

    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

  1. 1

    When 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.

  2. 2

    Inside 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.

  3. 3

    The 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.

Same fees day, night or weekend.

Seized & Jammed Lock Opening: questions

Advice · (249) 486-8066

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.

Why is it always the shaded side of the building that seizes?

The face of a building that never sees direct sun stays colder and damper, so ice in a keyway lasts days longer there and condensation sits in the cylinder rather than drying off. Wind-driven rain and snow tend to hit the same face. Those doors deserve a keyhole cover, a storm door where one fits, and a lubricant check before the season turns, and they are often the first lock a locksmith asks about.

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.

What the census means at the door

47%

Homes of every age. About 47% of homes in Tiny were built in 1980 or earlier, according to the 2021 Census.

Mixed housing stock keeps a locksmith versatile. A morning might be a heritage mortise lock rebuilt and an afternoon a smart lock paired to a phone on a steel door. The same care goes into both, with tools and parts for each.

97%

Mostly houses. Single-detached houses make up about 97% of homes in Tiny (2021 Census).

Where the housing is mostly single houses, the door into the house from an attached garage is easy to overlook because it feels indoors. It is still an exterior door, and a proper deadbolt there is a sensible, low-fuss upgrade.
