Lock Replacement & Upgrade in Sonya
Three teenagers, a dog walker, a cleaner and one house key that keeps going missing.
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
Who is asking for the change
The first check is about the person, not the door. An owner can change any lock on their home. A tenant who wants new hardware on the unit door needs the landlord's agreement, and a landlord who changes a lock while a tenant lives there hands over new keys. The locksmith asks which situation applies and, where paperwork helps, looks at identification, a deed, a lease or a property-management note. It takes a minute and it means the new lock goes on with everyone who has a stake in the door knowing about it, which is exactly how a lock should start its working life.
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.
An opening that is stronger, not just newer
Where the strike was reinforced, the improvement is mostly invisible and worth understanding. Long screws now tie the strike through the jamb into the framing, the pocket has been cut to take the whole bolt, and any split wood has been repaired. Together these make the frame the equal of the deadbolt, which is the part most break-ins defeat. The locksmith points out what changed so you can check it yourself: a bolt that seats fully with the door closed and a strike that stays put under a firm push. A twice-yearly look at those screws keeps it that way.

What affects the quote
Smart lock setup
Fitting a keypad or smart deadbolt includes programming codes, pairing to a phone or hub and calibrating the bolt, which is time on top of the mechanical installation and is named in the quote.
Special-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.
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 doors are you thinking about, and what is on each one now?
- 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
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.
My deadbolt only locks if I push the door. Will a new lock cure that?
The push is a sign the bolt and the strike pocket are out of line, which is a door and frame matter more than a lock fault. A new deadbolt is welcome if the old one is worn, but the visit also adjusts the strike, deepens the pocket or tightens hinges so the bolt throws freely with the door simply closed. Done together, the door locks with a fingertip and the new hardware works as designed.
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.
