Lock Replacement & Upgrade in Oro Park
The century home's original mortise lock takes a key the size of a spoon, sticks in humid weather and has worn its strike to a groove. You want a lock that works every day without giving up the old door.
Lock Replacement & Upgrade
In plain words
A replacement lock has to fit holes that already exist, and that is where the visit begins. The locksmith measures the backset, the distance from the door edge to the centre of the bore, which on most doors is 60 or 70 millimetres, checks the cross-bore diameter and edge-bore size, notes door thickness and handing, and looks at the strike cut-out. Most residential hardware is made to these standard preparations, so the new lock usually drops into place with no new drilling. Where a mortise lock or a thick door departs from the norm, filler plates, extension kits or a careful new bore bring the door up to standard.
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.

How the visit goes
The rest of the openings
One failing lock is often the loudest of several, so the locksmith takes a short tour. The back door, the garage man-door, a basement walkout, a sliding patio door and a storm door all count, and so does the door from the garage into the house, which is often the lightest lock on the property. Each is noted for grade, condition and whether it has a deadbolt at all. You are not obliged to do them all at once; the value of the tour is a clear list ranked by what matters most, so the first replacement goes where it makes the largest difference.
Adapting older and unusual doors
Not every door is a standard modern slab. A century home with a mortise lock may keep its case and get a new cylinder and strike, or take a filler plate that lets a cylindrical deadbolt sit where the old case was, without hacking at the original stile. A door thicker than 45 millimetres gets extended spindles and screws. A sliding patio door gets a replacement mortise hook lock or a keyed surface bolt sized to the rail. Steel and fibreglass doors are drilled only with the right bits and a jig, and a new deadbolt above an existing knob is bored with a template so it sits square.
A record of what went on the door
You are told plainly what was fitted: the maker and model, the grade, the function and finish of each lock, whether the strike was reinforced, and how the doors are keyed. The instruction sheets and packaging stay with you, since they carry the model numbers needed for a matching lever or a spare cylinder later. The old hardware is handed over or taken away as you prefer; a sound old cylinder can be worth keeping as a spare. For a rental, this account doubles as the note a landlord or property manager will want about the new keys.

What affects the quote
Same fees day, night or weekend
1Special-order hardware
Most standard locks come from the van. A specific style, an unusual finish or a restricted system may need ordering, which affects scheduling and is noted in the quote rather than discovered on the day.
2Finish 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.
3Condition of the old hardware
Hardware that comes off cleanly is one thing; painted-over trim, seized or stripped screws and a cylinder that has to be drilled out add time before the new lock can go on.
Lock Replacement & Upgrade: questions
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.
Can I stop people copying my house key?
A restricted keyway helps with that. The key blanks are controlled by the manufacturer and its authorised locksmiths, so a copy generally requires the card, record or authorisation the program uses, cutting down on copies made at an ordinary kiosk. It suits homes where keys are lent to cleaners, contractors or tenants. The cylinders are fitted in the normal way, and you keep the key card safe because it is what future copies depend on.
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.
