Seized & Jammed Lock Opening in Riverdale

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

When the cylinder is the part that has seized, the work is about cleaning rather than force. Keyways collect dust, salt spray, metal filings and residue from sprays never meant for locks, and over time the pins stop lifting cleanly. The locksmith flushes the plug with a contact cleaner, applies a penetrating lubricant, and works the key in small movements until the plug turns. With the door open the cylinder comes out, is stripped and cleaned, gets fresh springs or pins where worn, and is dressed with the lubricant specified for that cylinder. A plug or shell that is worn, damaged or eaten through by corrosion is what gets replaced.

Sound familiar?

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. This morning it feels set in concrete, and pushing harder only makes the key flex.

How the visit goes

  1. 1

    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.

  2. 2

    Proving it with the door open and shut

    The job is finished with testing rather than with the last screw. The bolt is thrown and drawn back with the door open to prove the lock itself, then with the door closed to prove the door and strike, then from the inside with the thumb-turn or lever. Every key you hold is tried, including the spare from the drawer. If the door is a main exit, the locksmith confirms it opens from inside with one motion and no key. Any hardware that was adjusted is cycled a dozen times to make sure it stays put, and the finish is wiped clean of cleaner and lubricant.

  3. 3

    What was done, in writing, with the old parts

    You are told plainly which family the jam belonged to and what was done: cylinder cleaned and rebuilt, tailpiece replaced, strike moved, hinges shimmed, mortise spring fitted, or cylinder replaced and keyed to your existing key. Replaced parts are handed over so you can see the wear or the break for yourself. For a rental, tenants and landlords both benefit from that note, since it records that the lock was serviced rather than changed. For an owner it goes in the home file beside the keyway and key code, which makes the next key cut or the next service a shorter conversation.

In the van

  • Replacement cylinder
  • Key blanks and code cutter
  • Long hinge screws
  • Strike plate and hinge shims
  • Lock de-icer

What affects the quote

  1. 1

    Small parts behind the cylinder

    Tailpieces, cams, springs, cylinder caps and pins are minor items, but each one used is named on the quote so you can see what went into the lock.

  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

    Door 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.

Same fees day, night or weekend.

Seized & Jammed Lock Opening: questions

Advice · (289) 806-2827

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.

Does road salt affect door locks?

Yes, especially on side doors near a treated driveway or walkway. Salt spray dries into a crust inside the keyway and around the plug, and each thaw dissolves and re-deposits it deeper. Over a few winters it pits brass and makes the pins drag. The remedy is a flush with contact cleaner, a thorough drying, and a dry lubricant that sheds moisture, followed by rinsing the hardware when the weather allows.

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.

What the census means at the door

58%

Older homes. About 58% of homes in Toronto were built in 1980 or earlier, according to the 2021 Census.

Established homes often have non-standard bores and backsets from an earlier generation of hardware. A locksmith working in such an area carries adapter plates and cylinders in the older sizes, so an upgrade fits the existing door instead of forcing a new one.

23%

Single-detached houses make up about 23% of homes in Toronto (2021 Census).

Where most people live in townhouses, apartments or condos, doors come in two kinds: the suite door you control and the shared entrances the building manages. A locksmith works on your door freely and coordinates with management on the rest.
