In plain words

This service has a season here. The first wet fortnight of winter sends meltwater into keyways that freezes overnight, and doors on the north and shaded sides of a building stay iced the longest. Salt spray from driveways and walkways leaves a crust that thickens with every thaw. Then summer humidity swells wood doors until the bolt drags in its pocket. A jammed lock opening in these conditions means thawing without boiling water, flushing out salt, drying the cylinder, and dressing it with a lubricant that sheds moisture, along with a check of the door so the same weather does not jam it again next month.

Sound familiar?

You are inside, the deadbolt is thrown, and the thumb-turn will not budge. It moved a little last week with some effort. Now the door you walk through every day is a wall, and you need it open.

How the visit goes

  1. 1

    Loading the door while the key is worked

    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.

  2. 2

    Inside a mortise case or lever set

    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.

  3. 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

  1. 1

    How many locks are affected

    One seized side door is the simplest case; a front and back door that both drag, or a storefront with two leaves, adds hardware and time to the visit.

  2. 2

    Mortise 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.

  3. 3

    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.

Seized & Jammed Lock Opening: questions

Advice · (289) 816-4986

Why do locks jam more in winter?

Two reasons meet in the same season. Freeze-thaw weather sends meltwater into the keyway by day and freezes it by night, and cold thickens any old grease or oil that has been sprayed into the pins. At the same time dry, heated indoor air shrinks wood doors so bolts move in their pockets. Doors on the shaded or windward side get the worst of it. A dry lubricant, a keyhole cover and a check of the strike after the first hard frost take care of most of it.

My key turns all the way round but the bolt stays put. What has broken?

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.

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 the census means at the door

47%

Homes of every age. About 47% of homes in Burlington were built in 1980 or earlier, according to the 2021 Census.

Mixed housing stock keeps a locksmith versatile. A morning might be a heritage mortise lock rebuilt and an afternoon a smart lock paired to a phone on a steel door. The same care goes into both, with tools and parts for each.

50%

A mix of homes. Single-detached houses make up about 50% of homes in Burlington (2021 Census).

Where the housing is mixed, expectations about what can be changed differ. A homeowner in a house decides everything; a condo owner works within house rules on the outer face. The locksmith knows which conversation to have at which door.
