Lock Replacement & Upgrade in Keelesdale
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
Moving into a home is the classic moment for this service, because you inherit whatever hardware and whatever key copies the previous owners left behind. The locksmith walks every exterior door with you and sorts the locks into three piles: sound hardware worth keeping and rekeying, worn hardware worth replacing, and doors with no deadbolt at all. Everything that stays is pinned to one new key, new locks are keyed to match, and old copies floating around town stop mattering. You leave the visit knowing exactly which key opens which door and how many of them exist.

How the visit goes
The door and frame around the lock
A new lock inherits whatever the door and frame are doing, so both get a look. The locksmith checks whether the door has dropped on its hinges, whether weatherstrip is pushing it out of square, and whether the bolt lands squarely in the strike pocket or rubs its edge. The pocket depth matters as well: a bolt that reaches the back of a shallow pocket is not fully thrown. Hinge screws, a jamb split from an old forced entry and a strike held by short screws are all noted, because the visit will tidy them up so the new hardware works as designed.
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.
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
1Smart 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.
2Older 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.
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
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.
What is a reinforced strike, and is it worth adding?
A standard strike is a thin plate held by two short screws in the jamb, and the jamb is what splits when a door is forced. A reinforced strike or strike box is heavier and is fixed with long screws that pass through the jamb into the framing, spreading the load into the structure. It is one of the most effective upgrades on any exterior door and is usually fitted as part of a deadbolt replacement.
Is a smart lock a good upgrade, and what happens when the batteries run out?
For a household with many people coming and going, codes that can be added and removed are a real convenience. Behind the keypad it is still a deadbolt, so grade and strike matter as much as ever. Batteries typically last months and the lock warns you as they fade; depending on the model, a dead battery is handled with a mechanical override key or with external contacts for a temporary power source, so it is worth confirming which one your lock uses.
