- The call
- The century home's original mortise lock takes a key the size of a spoon, sticks in humid weather and has worn its strike to a groove. You want a lock that works every day without giving up the old door.

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.
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.

Lock Replacement & Upgrade · North End

Scene 1
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.
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
If the door belongs to a rental unit, the visit finishes with the keys in the right hands. When a landlord orders the change, giving the tenant a full set of new keys is standard practice. When a tenant orders it with the landlord's consent, a key for the landlord is cut alongside the household's and the consent is noted. The locksmith can leave a short written record of the hardware fitted and the keys issued for the property file, so both sides know what is on the door and nobody is surprised at the next inspection or move-out.

Rekey when the hardware is sound and the problem is the key: a lost copy, a move, or too many keys for one house. Replace when the mechanism itself is worn, the housing or bolt is damaged, the grade was never suitable for the entrance, or you want a different function, finish or a keypad. Many visits do both, keeping good locks and rekeying them while replacing the tired ones, all to one key.
Yes, and it is a common change for anyone who finds a knob hard to grip. Levers use the same bore and backset as knobs, so the swap is usually a direct fit. Levers are handed, so the locksmith checks which way the door swings and chooses or adjusts the lever accordingly. A keyed entry lever pairs well with a deadbolt above it, and interior passage and privacy levers complete the set.
It is yours. Some people keep a sound old cylinder as a spare or move a decent deadbolt to a shed or garage door, and the locksmith can rekey it to the house key for that purpose. Worn or damaged hardware is taken away for recycling if you prefer. Either way, the old keys should be gathered up and discarded so nobody confuses them with the new set.
