Lock Replacement & Upgrade in Port Rowan
The lever on the side door droops toward the floor and rattles in your hand.
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 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.
Installing a keypad or smart deadbolt
A smart lock is fitted like any deadbolt, then brought to life. The bolt and exterior keypad go on first, the interior module with its battery pack after, and the door is closed so the lock can learn where the bolt sits; a bolt that meets resistance in the strike is corrected before pairing, because a straining motor drains batteries and fails early. Codes are programmed for each person, auto-lock and sound settings are set to your liking, any phone or hub pairing is completed, and the mechanical override cylinder is tested with its key. Fresh batteries go in last.
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
Keying alike and rekeying
Pinning new cylinders to one key and repinning existing locks to match is work per cylinder, so a whole house on a single key is quoted by the number of locks joining it.
Grade of hardware
A light Grade 3 knob set, a residential deadbolt with a strong label rating and a Grade 1 commercial-style deadbolt are different products at different levels, and the quote follows the grade you choose for each door.
Number of doors
One back door is a small visit; the front, back, side, garage man-door and patio slider together are a longer one, though several doors done at once share the travel and setup.
What to have ready
- Which finish should the new hardware match?
- Do you own the home, or rent it with the landlord's agreement to change locks?
- Do you want every exterior door to open with one key?
Lock Replacement & Upgrade: questions
QuestionsMy door has glass beside it. Should I fit a deadbolt keyed on both sides?
A keyed interior cylinder means finding a key to get out, which is not what you want on a door people use every day. The steadier answer for a door with glass is a single-cylinder deadbolt with a thumb-turn, combined with a reinforced strike, a longer bolt and a security film or laminated glass in the sidelight.
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.
My old house has a mortise lock. Can it take modern hardware?
Often the original case can be kept and given a new cylinder and strike, which keeps the period look and the old door intact. Where the case is beyond service, a filler or conversion plate covers the mortise pocket and lets a cylindrical deadbolt or knob set be fitted without cutting into the door's stile. The locksmith looks at the door before recommending either path, since old doors vary a great deal.
