Vintage Mortise Lock Service in Rouge Hill
After a wet summer the entry door sits lower in its frame. The lock works perfectly when the door is open, but with it shut you have to lift the handle and shoulder the door to get the deadbolt to throw.
Vintage Mortise Lock Service
In plain words
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.
How the visit goesThe 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.

How the visit goes
Repair, replacement cylinder or replacement case
The last step of the check is deciding what the lock needs, in plain terms, before any of it is done. Most cases need cleaning, springs and adjustment, and that is the recommendation. A cylinder lock with a worn plug may be better served by a new mortise cylinder of the same thread and cam, keeping the case. A cracked case, a bolt worn thin or a hub broken through calls for a replacement case in the same pocket, and the locksmith measures for it on the spot. You hear which of these applies and why, and if the answer is a replacement case, the choice between a reproduction and a modern case is yours to make.
Putting the door edge right
Before the case goes back, the pocket and screw holes get whatever attention the check turned up. Stripped holes are drilled out, plugged with glued hardwood dowel and re-drilled so the faceplate screws bite. A pocket that has loosened is packed with a thin hardwood shim glued to one wall so the case sits tight. A split at the edge is glued and clamped. None of this changes the door's appearance; it simply gives the rebuilt lock something solid to sit in, which matters because a case that shifts in its pocket will bind the spindle and undo the bench work in a few months.
A lock that feels new and looks old
What you get back is the door you had, with the lock working as it was designed to. The knob returns level with a snap, the latch catches when the door is pushed shut, the deadbolt throws with a light turn of the key or the thumb-turn, and the key goes in and out without a wiggle. Nothing on the face of the door has changed except that the brass has been cleaned where it was handled. The locksmith runs through each function with you from both sides before leaving, so the standard of what has been done is something you have seen, not something you have been told.

What affects the quote
Same fees day, night or weekend
1Parts that must be ordered
A reproduction case or an unusual cylinder size may have to be ordered to measurement, which means a second visit to fit it. The quote separates the first visit from the return.
2Missing or mismatched trim
Sourcing a knob, escutcheon or thumb-turn to match the survivors, from salvage or reproduction stock, is quoted as parts plus the search. Reusing your own trim from another door avoids that line.
3Making the inside key-free
Fitting a thumb-turn or interior release to a deadbolt that was keyed on both sides is its own small item, and one most owners of an entry door choose to include.
Vintage Mortise Lock Service: questions
How long does servicing a mortise lock take?
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.
How should I look after the lock once it is serviced?
A drop of the right lock oil into the latch and bolt once a year is plenty. If the lock has a pin-tumbler cylinder, use whatever lubricant that cylinder's maker specifies, since some take a dry graphite or PTFE product and others a specified liquid one. Try the latch and deadbolt each spring and fall; if the bolt starts to scrape, the strike wants a small adjustment before anything is strained. Keep bit keys out of a pocket where they bend.
Is it worth repairing an old mortise lock instead of replacing it?
Usually, yes. The mechanisms are simple and robust, and what fails is nearly always a spring, dried grease or wear on one part, all of which are repairable on a bench. Replacing the lock with a modern cylindrical set means boring a large hole through the door stile and filling the old pocket, which is more work and changes the door for good. A rebuilt case keeps the original trim and keeps the door intact.
