The brass knob on the front door of your century home turns, but nothing happens on the other side. The latch stays tucked in, the door swings free, and the only thing holding it shut is the deadbolt and a bit key that has worn down to a nub.
Keys are the part of the job people expect to be impossible, and they rarely are. A bit key, the skeleton key style used on older doors, is cut and filed on the bench to the wards and levers of your particular case, so a lost key can be replaced from the lock itself. A round cylinder on a later mortise lock is rekeyed like any modern cylinder, or exchanged for a new cylinder of matching thread and cam if it is worn out. Either way the service ends with keys in your hand that turn the original lock, and a spare made while the case is on the bench.

Scene 1
The mortise pocket and the screw holes in the door edge carry the whole lock, so their state is part of the assessment. The locksmith probes the faceplate screws for grip, looks for cracks running from the pocket into the stile, and checks whether an earlier repair enlarged the pocket or packed it with something soft. Stripped holes, a split edge or a case that shifts when the knob is turned change the plan: dowelling and re-drilling, a hardwood filler, or longer screws may be needed before the rebuilt case can be trusted. Finding this now avoids surprises once the lock is back in the door.
Scene 2
With the cover screws out, the case opens like a book: the latch bolt with its spring, the hub the spindle passes through, the deadbolt with its lever or tumblers, and the springs holding each in place. The locksmith notes what is broken, worn or merely stuck, then cleans the case with solvent and a brass brush until the old grease and rust are gone; old paint on the hardware is treated as a possible lead hazard and cleared with contained, lead-safe methods rather than dry brushing. Parts are cleaned individually, burrs are dressed off the bolts, and the hub square is checked against a fresh spindle to see whether it has rounded.
Scene 3
Anything that came out of the lock, a broken spring, a worn lever, the old cylinder, is offered to you rather than thrown away; some owners keep the originals with the house's papers. The locksmith leaves a short account of what was done: the case type and size, what was replaced, whether keys were made or a cylinder rekeyed, and how the strike was adjusted. For a designated heritage property this record shows the original hardware was retained. For everyone else it is simply the sheet you hand to the next locksmith, or the next owner, so nobody has to rediscover what is inside the door.
What shapes the quotePeru Lock Services
FeesSame any hour
A single entry lock that needs cleaning, springs and a strike adjustment is generally done in one visit of an hour or two. Filing a bit key adds bench time, and a set of interior latches is longer simply because there are more of them. A case that needs a part fabricated, or a replacement case that has to be ordered to size, may mean a second visit; the locksmith says so at the assessment.
A lock you have tested yourself from both sides, keys counted into your hand with a spare, any parts that were removed if you want them, and a short written note of what was done: case type, parts replaced, keys made, strike adjusted. For a bit-key lock the locksmith keeps the details needed to cut further keys later. You also get shown where the yearly drop of oil goes.
Two causes cover most cases. Either paint has built up on the faceplate, the bolt or the strike so the bolt drags across it, or the door has dropped so the bolt is entering the strike pocket at an angle and rubbing its edge. Occasionally a bent deadbolt lever inside the case adds friction. Cleaning the paint back, adjusting the strike and checking the lever all happen as part of the service.
