You are inside, the deadbolt is thrown, and the thumb-turn will not budge. It moved a little last week with some effort.

Seized & Jammed Lock Opening

In plain words

Most seized locks can be saved, and keeping your existing hardware is the aim. A cylinder that has stopped turning is usually recoverable with cleaning and fresh internal parts. A failed tailpiece is a small component swapped without touching the rest of the lock. A bolt bound by the door needs adjustment, not new hardware. Replacement is the answer for a plug or shell that is worn, damaged or hollowed out by corrosion beyond what cleaning and parts can fix, and then the new cylinder is matched to your keyway and finish and, where possible, keyed to the key already in your pocket.

Sound familiar?

The old mortise lock on the front door of the house turns the key halfway and stops with a dull clunk. It has been getting harder for months, and the brass key is starting to show a bend.

How the visit goes

Midland

How the visit goes

  1. Which of the three families it belongs to

    Every jammed lock falls into one of three groups, and sorting it is the whole diagnosis. A key that enters fully and will not turn points to the cylinder: grit, ice, corrosion, dried lubricant or a plug that has not returned to its neutral position with the shell. A key that turns freely and moves nothing points to the connection behind the cylinder, the tailpiece or cam, or to a broken hub in a mortise case. A key that works only when the door is pushed, pulled or lifted points past the lock entirely to the door and its strike. Each group has its own opening method and its own repair.

  2. Stripping and rebuilding the cylinder on the bench

    With access restored, a cylinder that seized gets a proper service. The locksmith removes it from the door, slides the plug out with a follower so the top pins and springs stay put, and lays out the pin stacks. Everything is cleaned, worn bottom pins and tired springs are replaced, and any burr on the plug is dressed. The plug is reassembled to the same combination so your existing keys keep working, then lubricated with the product that cylinder's maker specifies and cycled until it turns with a fingertip. If the key that jammed was worn, a fresh one is cut from the code rather than from that key.

  3. Keeping the cylinder clean and dry

    A serviced cylinder stays that way with very little effort. At the interval and with the product that cylinder's maker specifies, a short burst of lock lubricant into the keyway followed by a few turns of the key is enough; stay with that one product, since mixing lubricants makes a paste. Household oils, penetrating sprays and silicone meant for hinges belong nowhere near the pins, because they thicken and attract grit. Wipe the key before it goes in on a muddy or salty day. If the lock ever starts to drag, a puff of lubricant is the first response, and a call is the second.

What affects the quote

Same fees day, night or weekend

  1. 1Mortise 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. 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. 3Service or replace the cylinder

    A cylinder that can be stripped, cleaned and rebuilt is quoted as labour with a few small parts; one corroded through is quoted with a replacement cylinder matched to your finish and keyway.

Seized & Jammed Lock Opening: questions

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.

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.

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.
