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?

You are inside, the deadbolt is thrown, and the thumb-turn will not budge. It moved a little last week with some effort. Now the door you walk through every day is a wall, and you need it open.

How the visit goes

  1. 1

    The key in your hand

    Before blaming the lock, the locksmith looks at the key. A key that has been copied from another copy several times drifts away from the true cuts, a worn key no longer lifts the pins to the shear line, and a bent key binds before it is fully seated. If an original or a rarely used spare exists, it is tried; a lock that opens with the spare has told you the problem. Some cylinders also retain the key until the plug is returned to its neutral position, and a key that seems trapped may simply be a plug that has not come back. A fresh key cut from the code is a common outcome.

  2. 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. 3

    A door that closes without a fight

    If the door was the cause, the hinges, strike and seal have been set so the bolt has room. Keeping it that way is a seasonal habit: each spring and fall, try the lock with the door closed and no pressure on it, and snug the hinge and strike screws if the door has begun to drop. Wood keeps moving with humidity, so a door that swells in August may need a touch on the strike in September. A door that suddenly needs a push to lock is telling you early, while the fix is still a screwdriver and not a seized bolt.

What affects the quote

  1. 1

    Mortise 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.

  2. 2

    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.

  3. 3

    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.

Same fees day, night or weekend.

Seized & Jammed Lock Opening: questions

Advice · (289) 804-7704

Is a key stuck in the lock the same problem as a jammed lock?

They are close relatives. A key that will not come out is usually a plug that has not returned to its neutral position with the shell, a cylinder cap that has loosened, debris in the keyway, or a cylinder that is pinned incorrectly; some cylinders are also designed to hold the key until the plug is returned. The locksmith frees the key first, without pulling, then treats the cause the same way as any seized cylinder.

How long does a jammed lock opening take?

It depends on which family the jam belongs to. A bolt bound by the door is often freed in minutes and the adjustment afterwards takes a little longer. A seized cylinder needs patient cleaning before it turns and a bench service after, and a frozen one needs thawing time. A tailpiece swap is short once the door is open; a mortise case service is longer. The locksmith gives a sense of the time once the cause is identified at the door.

How can I tell whether the lock or the door is the problem?

Try the key while gently pushing, pulling and lifting the door. If it frees up in one position, the bolt is being pinched by the frame and the door is the cause. If nothing changes, look at the key: does it go fully in and refuse to turn, or spin freely? The first points to the cylinder, the second to the tailpiece behind it. Tell the locksmith which you found and the right parts come in the van.

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.

Layers of paint build up on older doors and frames, and a lock that seemed to fail is sometimes a latch glued shut by the last coat. Part of the visit in an older area is freeing hardware, cleaning the edges and checking the door swings true.

23%

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

Townhouse rows often share a keyway chosen by the builder. A locksmith can move a household onto a keyway of its own so a neighbour's key, or a key from the construction phase, no longer has any chance of fitting.
