Lock Replacement & Upgrade
The lever on the side door droops toward the floor and rattles in your hand. The latch no longer springs back on its own, so the door drifts open behind you unless you pull it shut and check it twice.
Lock Replacement & Upgrade
In plain words
When people say upgrade they usually mean a heavier lock, and there is a real scale behind that word. Builders hardware in North America is graded to ANSI/BHMA standards, with Grade 1 the highest and Grade 3 the lightest, and residential products carry a separate label scoring security, durability and finish. A higher grade certifies stronger performance on the standard's own tests, and moving up often brings a longer hardened bolt, a sturdier housing, pins that resist picking and a strike built to anchor into the framing, though the exact features depend on the model. The locksmith explains which grade fits which door.
How the visit goesThe 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.

How the visit goes
Measuring the existing preparation
Before any product is chosen the door is measured. Backset first, the distance from the door edge to the centre of the bore, which on most doors here is 60 or 70 millimetres. Then the cross-bore diameter, the edge-bore size, the shape of the latch faceplate, the door thickness and the handing. The strike cut-out and any glass, trim or storm door that limits where hardware can sit are noted too. These few numbers decide which locks will drop straight into the door and which would need a filler plate, an extension kit or fresh drilling, so they are written down before the catalogue is opened.
Taking the old hardware off without harm
Removal is done with the same care as fitting. Interior trim screws come out first, then the interior rose or thumb-turn, and the exterior housing lifts away with its tailpiece. The latch or bolt slides out of the edge bore once its two faceplate screws are released, and the old strike comes off the jamb. Painted-over screws are scored free rather than forced, seized screws are eased with a hand driver of the right size, and a stripped head is drilled out only as a last step. The bore and edge mortise are then cleaned of paint build-up and debris so the new parts seat properly.
Keys counted, named and planned
You receive the agreed number of keys, cut from the new pinning and tried in every door they should open, plus any code cards for a restricted system, which are what future copies are cut from. It is worth deciding on the spot who gets one and where the spare lives, ideally with a trusted neighbour or in a lockbox rather than in a drawer inside. If the house is now on a single key, retire every old key so none can be confused with the new one. A written list of which key does what goes in the home file.

What affects the quote
Same fees day, night or weekend
1Condition 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.
2Changes to the door preparation
Adjusting a strike mortise is minor; boring a new hole for a deadbolt, fitting a filler plate over an old mortise pocket or adapting a thick door with extension kits is quoted as its own item.
3Patio and French door hardware
Sliding door mortise locks, foot bolts and flush bolts for an inactive French door leaf are specialty items sized to the door, and they are quoted as their own line beside the entrance work.
Lock Replacement & Upgrade: questions
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.
How do I look after a new lock so it stays smooth?
Very little is needed. Whatever lubricant and interval the cylinder maker specifies, worked into the keyway with a few turns of the key, keeps the pins free; using the wrong product collects grit instead of helping. Wipe salt off exterior hardware during winter melts. Snug the hinge and strike screws each spring and fall as the door moves with humidity. Cut spare keys from a crisp original rather than a worn copy.
Can every door in the house work from one key?
Yes, provided the cylinders share a compatible keyway, which the locksmith checks when choosing hardware. New cylinders are pinned on site to a single new key and any existing locks worth keeping are repinned to match. Front, back, side and garage doors commonly end up on one key, and a shed or gate padlock can join them. You then decide how many copies exist and who holds each.
