- The call
- 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.

The 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.
On storefronts, offices and older houses the hardware is often a mortise lock with a lever, and the jam is frequently inside the case, not the cylinder. A lever that swings without retracting the latch can point to a broken spring, a worn hub, or another fault in the drive path; a key that stops halfway can point to a bent spindle, an old case packed with dust, or a problem in the cylinder itself. Seized and jammed lock opening for this hardware means getting people through the door, then opening the case, cleaning the contact points, and fitting the part that gave up.

Scene 1
With the lock family narrowed, the locksmith puts a hand on the door. Pushing it into the frame, pulling it out, and lifting on the handle each change how a bound bolt sits in its pocket, and the key is tried gently in each position. If the key frees up under one of those loads, the door is the cause. Where a second entrance is open, the same lock family is compared with the door swung wide, since a bolt that throws smoothly in mid-air and binds when closed has been pinched by the frame. Nothing is forced during this test; it is a diagnosis, not an attempt.
Scene 2
For mortise locks and lever hardware the work moves from the cylinder to the case. The locksmith gets the door open, then removes the trim and draws the case out of the door edge. Inside, a broken lever return spring, a worn hub, a bent spindle or a latch that has lost its spring is replaced with the matching part, and years of dust and hardened grease are cleaned from the contact surfaces before a fresh application of a grease suited to lock mechanisms. The case is reassembled, the spindle and cylinder are refitted, and lever, key and thumb-turn are each tested so the latch and bolt travel fully.
Scene 3
Where a worn or drifted key was part of the jam, you now hold a key cut from the code or from a fresh master, and every spare has been tried in the lock. Retire copies that needed force, and cut future spares from the good key rather than from each other, since each generation of copying adds error. Label the keys if several locks are involved. If the cylinder was replaced and pinned to your existing key, the whole house is still on one key. Keeping a written note of the keyway and, where it exists, the key code makes any future key a simple cut.
What shapes the quoteAshburnham Lock Experts
FeesSame any hour
The key and cylinder are doing their job; the bar behind the cylinder that drives the bolt, called the tailpiece or cam, has broken, slipped or twisted out of engagement. It is a small part. The locksmith retracts the bolt through the mechanism or removes the cylinder to reach it, then fits a tailpiece of the right length and profile. Your cylinder and keys are unchanged afterwards.
It is a normal part of the visit and it protects you as much as anyone. Photo identification matching the address is the simplest route; a lease, a bill, a management record or a manager or neighbour who can confirm you works as well. For a business, the key holder or the person on the lease is enough. If the documents are behind the jammed door, the check is completed once you are inside, before the locksmith leaves.
Often, yes. A replacement cylinder in the same keyway can be pinned to the cuts on the key already on your ring, so the front and back doors stay on one key and nothing else in the house changes. If the old keyway is no longer made or the key is badly worn, the new cylinder comes with fresh keys and the other doors can be rekeyed to match in the same visit.
