Lock Replacement & Upgrade in Troy
The keys the seller handed over came in a sandwich bag: six unlabelled copies for two locks of different makes from different decades. You have no idea how many more copies exist or who is holding them.
Lock Replacement & Upgrade
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 goesThe house is fifteen years old and every exterior door still wears the light hardware the builder fitted: a short bolt, a thin strike held by two small screws, and a knob lock that never suited a street entrance.

How the visit goes
The key plan for the whole house
A lock is only half of a system; the other half is who holds which key. The locksmith asks how many exterior doors there are, which ones should open with the same key, whether a garage man-door or a shed should join them, and who in the household needs a key of their own. If keys have been lent out over the years, the plan can retire all of them at once. Where copying keys without permission is a worry, a restricted keyway can be offered. Settling this before the hardware is chosen means the new locks arrive ready to be pinned alike rather than fixed up afterwards.
Mounting the cylinder and the interior side
The exterior housing goes on with its tailpiece passing through the slot in the bolt, oriented as the maker specifies so the keyway sits upright. The interior thumb-turn or rose is offered up and the two long mounting screws are drawn down evenly by hand until firm, not crushed; zinc housings distort and threads strip under a drill, and an over-tight rose makes a lever heavy forever. On thick doors, extension kits bring screws and spindle to length. A knob or lever set adds the latch spindle and the spring cage, and the handle is checked to return crisply to level before the trim is snugged.
A clear plan for the remaining doors
Most households do not replace every lock in one visit, and you leave with a short list of what is left, in order of importance. Typically the front door and the garage-to-house door come first, then the back and side doors, then the patio slider and interior sets. Because the key plan has been settled, any lock added later can be pinned to the same key, so the house stays on one key as the work continues. Finishes and styles are recorded so future hardware matches. The first visit sets the standard; the rest of the house can follow when it suits you.

What affects the quote
Same fees day, night or weekend
1Restricted keyway system
Patented cylinders and controlled key blanks cost more than standard hardware and involve setting up your key records, which is quoted separately from an ordinary replacement.
2Door material and thickness
Wood, steel and fibreglass doors are drilled and fitted differently, and a door thicker than the standard 45 millimetres needs extension parts, so the door itself shapes part of the quote.
3Older and mortise hardware
Servicing an original mortise case, sourcing a compatible cylinder or fitting a conversion plate on a century door involves more assessment and fitting time than a standard cylindrical replacement.
Lock Replacement & Upgrade: questions
Can the same visit replace locks on more than one door, or does each door need its own appointment?
One visit usually covers every door on the job. The locksmith brings a range of cylinders and strikes, measures each door's backset and bore, and works through the list in order, front entrance first if a key change matters most there. Having a rough list ready, which doors, and whether they should end up on one key or several, lets the locksmith plan hardware before arriving rather than working it out door by door on site.
Is 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.
Can I replace only the deadbolt and keep my existing knob?
Yes. The deadbolt and the knob or lever are separate locks in separate bores, so one can be replaced while the other stays. The new deadbolt can be pinned to work on the same key as the knob if the keyways are compatible, and its finish can be matched to the knob so the door looks intended. Replacing the deadbolt first is a sensible order, since it does most of the securing.
