Seized & Jammed Lock Opening
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.

A lock rarely seizes without warning. It asks for a wiggle, then a firmer wiggle, then it needs the door pulled toward you, and one morning it stops. Seized and jammed lock opening deals with that morning, but the same visit deals with the months before it. The locksmith explains why this lock jammed, whether it was grit, weather, a worn key or a door that moved, and leaves you with a lubrication routine, a fresh key cut from code rather than from a tired copy, and a door that closes without a shove. The point is a lock that turns with two fingers and keeps doing so.
How the visit goesThe 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

- 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.

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.

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
Ice 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.

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.

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.
Same fees day, night or weekend.
Seized & Jammed Lock Opening: questions
The lever on our shop door goes down but the latch does not pull back. Is that a lock problem?
It usually points to the mortise case rather than the cylinder, and it is a common complaint on commercial doors. Inside the case a return spring, a worn hub, or another part of the latch's drive path can have failed, so the lever moves without driving the latch. The locksmith gets the door open, draws the case out of the door edge, replaces the worn part, cleans and greases the contact points and refits everything, then tests lever, key and thumb-turn together.
What should I tell you on the phone?
Say what the key does: refuses to turn, spins without effect, or works only when the door is pushed or pulled. Name the lock type if you can, whether it is a deadbolt, knob, lever or an old mortise lock, and which side of the building the door faces. Mention recent weather, any spray that went into the keyway, any other door you can use, and whether anyone is inside. That short list decides the tools that come.
My key is worn. Would a new copy have prevented this?
Possibly, if the key was part of the cause. A worn or bent key lifts the pins short of the shear line, so the plug binds even in a healthy cylinder, and a copy made from that key repeats the wear. A key cut from the code or from a crisp original is the fix. If the lock was also gritty or the door had moved, the new key would have eased things without settling them, which is why the locksmith checks all three.

What the census means at the door
38%
Homes of every age. About 38% of homes in Mississauga were built in 1980 or earlier, according to the 2021 Census.
In neighbourhoods with a mix of older and newer homes, the finishes on the doors vary widely: aged brass, satin nickel, matte black. A locksmith serving such an area keeps a range of finishes so replacement hardware suits each house.
37%
Single-detached houses make up about 37% of homes in Mississauga (2021 Census).
Where housing is mostly apartments and condos, mailbox locks are a regular call. A worn or lost mailbox key is a small job that a locksmith handles alongside the suite door, and the new lock comes with fresh keys cut on the spot.
