Lock Replacement & Upgrade in Pefferlaw
The lever on the side door droops toward the floor and rattles in your hand.
In plain words
Not every complaint about a lock ends in a new lock, and a good visit says so. A cylinder that turns stiffly may only need cleaning and fresh pins; a lost key calls for rekeying, which keeps the hardware and changes the key; a loose lever often wants a tightened spindle. Replacement earns its place when the mechanism is worn through, the housing is damaged, the grade was never adequate for the entrance, or you want a different function, finish or a keypad. The locksmith lays the three routes side by side so the choice rests on what the door needs rather than on what is in the van.
How the visit goesEvery morning the front door key needs the same little dance: push in, lift, wiggle, turn. It has been getting worse for a year, and this week it took three tries in the cold before the deadbolt finally gave.
Lock Replacement & Upgrade
How the visit goes


The door and frame around the lock
A new lock inherits whatever the door and frame are doing, so both get a look. The locksmith checks whether the door has dropped on its hinges, whether weatherstrip is pushing it out of square, and whether the bolt lands squarely in the strike pocket or rubs its edge. The pocket depth matters as well: a bolt that reaches the back of a shallow pocket is not fully thrown. Hinge screws, a jamb split from an old forced entry and a strike held by short screws are all noted, because the visit will tidy them up so the new hardware works as designed.
Fitting the latch or bolt to the door
Most modern latches and bolts adjust between the two common backsets, so the unit is set to the measured figure and slid into the edge bore. A spring latch goes in with its bevel facing the strike, while a deadbolt is oriented the way its markings or instructions call for, not by that bevel rule. The faceplate should sit flush in its mortise; where the old cut-out differs in shape or size, the mortise is trimmed with a sharp chisel, or a round drive-in collar is used where the door was prepared that way. The bolt is checked to travel freely before anything else goes on, since a bolt that binds in the door will bind under the key too.
Simple habits that keep new hardware new
New locks ask very little. Once or twice a year, or at whatever interval the lock maker specifies, a puff of the lubricant that maker calls for in the keyway and a few turns of the key keep the pins moving freely, since the wrong product for that cylinder gathers grit instead of helping it. In winter, wipe salt spray off the exterior hardware when it appears, since salt is the finish's main enemy here. Each spring and fall, check that the hinge and strike screws are snug, because wood doors move with humidity and a dropped door makes a good lock feel worn. A key that starts to need coaxing is an early word from the cylinder.

What affects the quote
Strike reinforcement and jamb repair
A reinforced strike with long screws is a modest addition; repairing a jamb split from a forced entry, or fitting a strike box into a frame that has never had one, adds labour and materials.
Authorization needed from a property manager or landlord
A rental or condominium unit sometimes needs sign-off from a property manager or landlord before a lock is changed, and new keys may need to reach more than one party afterward. Confirming who is authorized and who receives keys is worked out before the new hardware goes in.
Finish and style
Standard satin nickel or brass is one line; specialty finishes, matched suites across several doors and designer handlesets are others. The finish you choose for exposure and looks is priced as the maker prices it.
What to have ready
- Has the door been forced or damaged, or does it need a push to lock?
- Which finish should the new hardware match?
- Are you interested in a keypad or smart lock on any door?
Lock Replacement & Upgrade: questions
QuestionsIs it possible to upgrade just the exterior locks now and handle interior doors later?
Yes, and it is a common way to spread the work out. Exterior doors carry the security load, so starting there with a graded deadbolt and a reinforced strike covers the part that matters most first. Interior locks, passage sets, privacy locks on bathrooms and bedrooms, can be scheduled for a later visit without affecting anything already done, and the locksmith can note what was fitted so the second visit matches it.
What happens to the old lock?
It is yours. Some people keep a sound old cylinder as a spare or move a decent deadbolt to a shed or garage door, and the locksmith can rekey it to the house key for that purpose. Worn or damaged hardware is taken away for recycling if you prefer. Either way, the old keys should be gathered up and discarded so nobody confuses them with the new set.
Can you replace the lock on a sliding patio door or French doors?
Yes. Sliding doors take a replacement mortise hook lock sized to the rail, often with a keyed exterior, and benefit from a secondary foot bolt or a pin through the frames. French doors are secured by treating the inactive leaf properly with flush bolts into the head and sill, then fitting a deadbolt to the active leaf with a strike into that reinforced edge. Both are routine parts of a residential upgrade.
