Seized & Jammed Lock Opening
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.
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.
How the visit goesThe key turns a full circle without any resistance and the deadbolt stays exactly where it is. There is no click, nothing moves behind the face of the lock, and the door is as closed as it was before you touched it.

How the visit goes
Whose door, and which door
The first check is the person, not the lock. The locksmith confirms that whoever is asking for the opening is entitled to it, usually with photo identification that matches the address, or a lease, deed, property-management record or a manager who can vouch for you. For a business, a key holder or the person named on the lease is enough. If everything that proves it is behind the jammed door, the check is finished once you are inside and before the locksmith leaves. Then a short walk to the other entrances: a second door on the same key gives a comparison lock and sometimes a gentler way in.
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.
A lock that turns with two fingers
You leave with a lock that operates the way it did when it was new: the key seats fully, the plug turns without a wiggle, the bolt throws and retracts through its whole travel, and the door closes and locks without a shoulder. The locksmith has cycled it from both sides and with every key, and has shown you where the trouble was, whether that was a gritty keyway, a broken tailpiece or a strike plate a few millimetres out. If you had a habit of lifting the door or pulling it toward you to lock it, that habit is now retired.

What affects the quote
Same fees day, night or weekend
1Matching 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.
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.
3Inside 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.
Seized & Jammed Lock Opening: questions
How do I stop this from happening again?
Three habits cover most of it. Lubricate the cylinder with a dry lock product twice a year and keep oils out of it. Check that the door locks with no pressure on it each spring and fall, snugging hinge and strike screws when it starts to drag. Keep a lock de-icer handy and fit a keyhole cover on exposed doors. And act on the first stiff turn, because a lock that still turns is a smaller job than one that has stopped.
What is a tailpiece, and why does it matter here?
The tailpiece is the flat bar that sticks out of the back of a deadbolt cylinder and turns the bolt mechanism when the key turns; on a knob or lever set the equivalent part is a cam or spindle. It carries all the twisting effort, so a bent, worn or broken one is the reason a key can turn without anything happening. It is a small part to replace, it comes in several lengths, and the right length matters.
What lubricant should I use afterwards, and how often?
Whatever lubricant and interval the cylinder's manufacturer specifies, applied with a few turns of the key. Stay with that one product, because mixing different lubricants can make a paste. Oil, hinge silicone and general-purpose penetrating sprays are kept out of the keyway. Lock manufacturers describe cleaning the cylinder with an electronic contact cleaner before lubricating, and that is the order the locksmith follows on a service too.
