Seized & Jammed Lock Opening
It is the coldest morning of the winter and the key goes halfway into the side door and stops. There is frost on the face of the cylinder, and the door on the shaded side of the house has done this before.

A jammed lock looks like one problem from outside and is usually one of three inside. The cylinder itself may have seized, packed with grit, corrosion or old grease. The link between cylinder and bolt, the tailpiece or cam, may have broken, which is why a key can spin without doing anything. Or the lock may be healthy and the bolt simply pinned against the strike by a door that has moved. Seized and jammed lock opening starts by telling those apart, because the right answer for one would damage the hardware in another. Once the culprit is known, the door is opened and the cause is repaired.
How the visit goesThe 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
- 1
What is inside the keyway
A small mirror and a bright light show what the keyway has collected. Salt crust, sand, metal filings, sawdust from a renovation and the gummy residue of household spray oils are all common, and each reads differently: a dry gritty feel, a sticky drag, or a plug that will not accept the key to full depth. Ice shows as frost on the cylinder face and a key that stops short. A cylinder cap that has loosened lets the plug sit crooked so the pins never line up. This look decides whether the cylinder needs a flush and dry lubricant, a thaw, a re-tightened cap, or a full strip on the bench.

When corrosion has taken the core
Occasionally the plug or shell has rusted or pitted past the point of cleaning, or an earlier forcing has twisted the plug in the shell. Then the cylinder is replaced rather than rebuilt. The locksmith matches the keyway and finish so the new part looks like the old one, and where the keyway allows, pins the new cylinder to the key already on your ring so nothing else in the house changes. If the whole lockset is tired, a replacement deadbolt or lever set goes on in the same visit, with the strike checked to suit it. The old parts are handed over so you can see exactly what failed.

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
- 1
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.

Matching finish and keyway
A replacement that has to match an unusual finish or a restricted keyway takes a specific part rather than a stock one, and the quote reflects the part.

Keying a new cylinder to your existing key
Pinning a replacement cylinder to the key already on your ring, or rekeying other doors to match a new key, is extra work per cylinder and simplest to do in the same visit.
Same fees day, night or weekend.
Seized & Jammed Lock Opening: questions
Will I need a whole new lock?
Usually not. Most jammed locks are saved by cleaning the cylinder, fitting a small part such as a tailpiece or spring, or adjusting the door so the bolt has room. A new cylinder is fitted when the plug or shell is corroded through or twisted by forcing, matched to your finish and, where possible, pinned to your current key. A complete new lockset is usually a choice you make rather than a requirement, though some internal failures cannot be serviced in place and call for a full replacement.
Should I spray something into the keyway while I wait?
Better not, unless it is a proper dry lock lubricant. Household oils, general penetrating sprays and hinge silicone thicken inside the cylinder and attract grit, so they buy a day and cost a service later. If the lock is frozen, a lock de-icer is fine; boiling water is not, since it refreezes deeper in. The most useful thing to do while waiting is to stop turning the key, so it does not bend or snap.
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
52%
Older homes. About 52% of homes in London 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.
49%
A mix of homes. Single-detached houses make up about 49% of homes in London (2021 Census).
In mixed neighbourhoods, a family may move from an apartment to a house or the other way around. A locksmith who knows both kinds of door can rekey the old place for the next occupant and set up the new one on the same visit.
