- The call
- The 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.

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.
After a break-in or an attempt, the door tells a story, and the new hardware should answer it. Splintered wood around the strike means the jamb gave before the lock did, so the repair pairs a heavier deadbolt with a reinforced strike and 75 millimetre screws that reach the framing behind the jamb. A bent bolt or cracked housing is replaced with a graded deadbolt whose bolt has a hardened core. A knob lock that was bumped or forced is swapped for a set with better pins. The aim is a whole opening that resists force, not merely a shinier lock.

Scene 1
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.
Scene 2
Most modern latches and bolts adjust between the two common backsets, so the unit is set to the measured figure and slid into the edge bore. A spring latch goes in with its bevel facing the strike, while a deadbolt is oriented the way its markings or instructions call for, not by that bevel rule. The faceplate should sit flush in its mortise; where the old cut-out differs in shape or size, the mortise is trimmed with a sharp chisel, or a round drive-in collar is used where the door was prepared that way. The bolt is checked to travel freely before anything else goes on, since a bolt that binds in the door will bind under the key too.
Scene 3
Before the tools go back in the van, each lock is operated from both sides with the door open, then closed, then closed hard against the weatherstrip. The latch should catch on its own when the door swings shut, the deadbolt should throw to its stop with a fingertip on the thumb-turn and no shoulder on the door, and the key should turn without lifting or jiggling. You are invited to try each one yourself and to lock up behind the locksmith. Anything that felt marginal has been adjusted, so the door you close that night behaves the same as the one you tested.

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.
