Seized & Jammed Lock Opening in Winona Park

The shop's lever handle goes down as usual, but the latch inside the mortise case never pulls back. Staff are waiting on the sidewalk with their coffees, the door is locked, and the handle is simply moving air.

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

Winona Park

How the visit goes

  1. Levers, thumb-turns and mortise cases

    Lever handles and mortise locks add parts that a plain deadbolt does not have, and each can jam on its own. A lever that drops without retracting the latch can have a tired return spring or a worn hub inside the case, though latch engagement, linkage, or the spindle can produce the same symptom. A thumb-turn that will not move can be a bent spindle, a stripped drive or a bolt pinned by the frame. On older houses and commercial doors the mortise case itself may be packed with decades of dust and dried grease. The locksmith works the lever, key and thumb-turn separately and feels where resistance starts, which locates the fault before the case is opened.

  2. Thawing ice and clearing salt

    Ice is melted, never chipped. A lock de-icer or gentle warmth on the cylinder face turns the frozen meltwater back to liquid so it can drain, and the key is then worked until the plug turns. Boiling water is kept well away, because it refreezes inside and can crack cold brass. Salt crust is flushed out with contact cleaner and the plug is dried thoroughly before any lubricant goes in, since salt and moisture sealed under lubricant keep corroding. The cylinder is then dressed with the lubricant specified for that product, applied once everything is dry. If the weatherstrip has frozen to the door, that bond is released and the seal wiped.

  3. For a business: a door the staff can rely on

    On a commercial door the handover includes the people who use it. Whoever opens in the morning is shown how the lever, key and cylinder now behave, and the exit side is demonstrated so everyone knows the door opens from inside with one motion. If the mortise case was serviced, the parts that were replaced are named so a future locksmith knows what is in there. A note of which keys were tested and who holds them supports whatever key control the business runs. Spare keys are checked in the lock before they go back in the safe.

What affects the quote

Same fees day, night or weekend

  1. 1Door and hinge adjustment

    When the door caused the jam, hinge screws, shims, a strike move or a deepened bolt pocket are quoted as their own line beside the opening.

  2. 2Ice and salt on the day

    A cylinder frozen solid or crusted with salt needs thawing, flushing and drying before it can even be diagnosed, and a winter call is quoted with that time in mind.

  3. 3Mortise and commercial hardware

    Drawing a mortise case, replacing a hub or spring and regreasing the contact points is more involved than a cylinder service, and storefront and exit hardware are quoted accordingly.

Seized & Jammed Lock Opening: questions

Why does the lock only stick when the door is closed?

Because with the door open the bolt is throwing into thin air, and with the door closed it is throwing into a pocket that has moved. A door that has dropped on its hinges, swollen with humidity or been pushed out by thick weatherstripping lands the bolt against the edge of the strike plate instead of through the hole. A chalk mark on the bolt shows exactly where it hits, and the fix is on the frame, not in the cylinder.

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.

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.
