Seized & Jammed Lock Opening

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.

Sound familiar?

The lock works, but only if you lean on the door with your hip while turning the key. After a week of humid weather the bolt is jammed against the strike plate, and without that push the key stops halfway.

How the visit goes

Burlington

How the visit goes

  1. What is inside the keyway

    A small mirror and a bright light show what the keyway has collected. Salt crust, sand, metal filings, sawdust from a renovation and the gummy residue of household spray oils are all common, and each reads differently: a dry gritty feel, a sticky drag, or a plug that will not accept the key to full depth. Ice shows as frost on the cylinder face and a key that stops short. A cylinder cap that has loosened lets the plug sit crooked so the pins never line up. This look decides whether the cylinder needs a flush and dry lubricant, a thaw, a re-tightened cap, or a full strip on the bench.

  2. 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.

  3. Set up for the freeze-thaw months

    After a winter jam the cylinder has been dried and dressed with a lubricant that sheds moisture, and you know the routine for the next cold snap. A keyhole cover or a storm door keeps meltwater out of an exposed lock. A tube of de-icer in the car or coat pocket is the answer to a frosted cylinder, and boiling water is never the answer. Rinse salt spray off hardware near a treated driveway or walkway when the weather allows. Doors on the shaded side deserve a check after the first hard frost, because they hold ice long after the sunny side has cleared.

What affects the quote

Same fees day, night or weekend

  1. 1Keying a new cylinder to your existing key

    Pinning a replacement cylinder to the key already on your ring, or rekeying other doors to match a new key, is extra work per cylinder and simplest to do in the same visit.

  2. 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.

  3. 3Matching finish and keyway

    A replacement that has to match an unusual finish or a restricted keyway takes a specific part rather than a stock one, and the quote reflects the part.

Seized & Jammed Lock Opening: questions

Will I need a whole new lock?

Usually not. Most jammed locks are saved by cleaning the cylinder, fitting a small part such as a tailpiece or spring, or adjusting the door so the bolt has room. A new cylinder is fitted when the plug or shell is corroded through or twisted by forcing, matched to your finish and, where possible, pinned to your current key. A complete new lockset is usually a choice you make rather than a requirement, though some internal failures cannot be serviced in place and call for a full replacement.

My key turns all the way round but the bolt stays put. What has broken?

The key and cylinder are doing their job; the bar behind the cylinder that drives the bolt, called the tailpiece or cam, has broken, slipped or twisted out of engagement. It is a small part. The locksmith retracts the bolt through the mechanism or removes the cylinder to reach it, then fits a tailpiece of the right length and profile. Your cylinder and keys are unchanged afterwards.

If the cylinder is replaced, can it be keyed to my existing key?

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.
