- The call
- The brass handleset has gone blotchy and green where the winter salt reaches it, and the coating on the deadbolt is lifting in flakes. It still locks, but it looks tired beside the fresh paint on the door.

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.

Scene 1
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.
Scene 2
When the brief is a stronger door, the new deadbolt is chosen for what is inside it: a bolt with a full 25 millimetre throw and a hardened steel insert that spins against a saw, a housing that stands low so a wrench has nothing to grip, and a cylinder with pins that resist picking and bumping. Fitting follows the normal steps, but the locksmith confirms the bolt reaches full extension with the door closed, because a high-grade bolt seated halfway into a shallow pocket behaves like a low-grade one. The strike is upgraded alongside it so both halves of the lock share the same standard.
Scene 3
A keypad or smart deadbolt leaves the visit with codes set for each person, auto-lock and alerts configured, and any phone pairing confirmed while the locksmith is there to check it. You are shown the low-battery signal so you recognise it, and the type of battery the maker calls for. The mechanical override key is the piece to look after: keep it on a keyring or with a neighbour rather than inside the home it opens. A second person's code is set up before the locksmith leaves, so a flat phone or a forgotten code is never a reason to stand on the porch.

The locksmith will ask, and it is a sign of a careful trade. Photo identification with the address, a deed or property tax notice, or a mortgage or insurance document is plenty for an owner. Tenants show a lease and the landlord's consent; landlords show ownership and confirm the tenant will receive keys. It is a short step that protects everyone with a right to that door.
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.
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.
