Locksmith DeFuniak

Old doors, old hardware, and what actually goes wrong with them

DeFuniak Springs has a housing stock that most of this part of Florida does not. Homes around the lake and through the older streets of town were built long before the hardware standards everyone now takes for granted, and a great many of them are still wearing their original door furniture. That produces a set of problems a locksmith who only works new construction never sees.

Mortise locks and why they are worth keeping

A mortise lock is not a modern lockset. Instead of two round holes bored through the door, it lives in a deep rectangular pocket cut into the door edge, and inside that pocket is a steel case containing the latch, the deadbolt, the handle spindle and the springs that return everything to position. It is a small machine, and unlike a modern cylindrical lockset it was designed to be opened, cleaned and repaired rather than thrown away.

That is the single most useful thing to know about them: a mortise case that has stopped working is usually repairable. The common faults are a broken or fatigued spring so the handle no longer returns and droops, a spindle worn square-to-round so the handle turns without moving anything, a latch bolt gummed with a century of dried oil and dust, or a lever pack that has never been cleaned. None of those require replacement of the case, and replacement is rarely straightforward anyway — pocket dimensions, backset, and the spacing between handle and keyhole vary enormously across the eras, and a modern case dropped into an old pocket usually means enlarging the mortise, which is irreversible damage to an original door.

Servicing one properly means removing the case from the door, opening it, cleaning out the old lubricant and grit, inspecting the springs and the lever pack, replacing what has failed, reassembling with a dry lubricant rather than a wet oil, and refitting. It takes longer than swapping a knob. It also keeps a door that is part of a house worth keeping.

Skeleton keys, warded locks, and what they really protect

The barrel-shaped keys people call skeleton keys generally operate either a warded lock or a simple lever lock. It is worth being plainly honest about these: they offer very little security by any modern measure, and anyone who tells you otherwise is selling something. Their value on an old house is different — they are original, they are part of the door, and on interior doors, closets and pantries where the lock exists for privacy rather than protection, they are entirely adequate.

The sensible approach on a historic home is therefore split. Keep and service the original hardware where it is doing a privacy job or where it is visible and matters to the house. Put real security on the doors that face the outside world, using either a modern cylinder discreetly fitted into the existing hardware where the case allows it, or a separate deadbolt positioned so it does not compete visually with the original set. What you should not do is accept a recommendation to strip the original hardware off a house because a catalogue is easier to work from.

Doors that have moved

A door that has stood in a frame for decades has been through many thousands of humid summers and dry winters, and it has not stood still. Wood slabs swell across the grain in the wet months and shrink back in the cool ones, hinge screws work loose in softened wood and let the slab drop at the latch edge, and the frame itself settles with the house.

The result is the complaint we hear most often here: the deadbolt only throws if you lift the door, or lean on it, or pull it toward you. Almost everyone reads that as a failing lock. It usually is not. Open the door fully and throw the bolt into open air — if it extends smoothly with the door open, the lock is healthy and the bolt is simply arriving at the strike plate off-centre. The repair is at the hinges and the strike, and it is far smaller than a new lock. Tightening or replacing hinge screws with longer ones that reach solid framing lifts a sagging door back into position; the strike can be adjusted or re-mortised to match where the bolt now lands.

The related problem is paint. Decades of repainting builds a film in the latch rebate, over the strike, and frequently across the face of the lock itself. Painted-over hardware binds, and painted-shut sash and casement window latches are effectively decoration. Stripping paint back out of a strike and off a latch face restores function without replacing anything.

Worn keys and worn cylinders on an old house

Where a modern cylinder has been fitted at some point in an old door's life, it has usually been there a long time. A brass key rounds off at the shoulders and at the peaks of its cuts, so the pins no longer reach the heights they were cut for. That is the stage where a key needs jiggling, or works for one person and not another, or works in the morning and not in the afternoon. If several copies exist and only one of them works reliably, the others are copies of a worn original and inherit its errors. Cutting a fresh key to the code, rather than tracing yet another copy, resolves it properly and gives you a master worth copying from in future.

Property outside the town limits

Inland Walton County is not just houses. A large share of the work here is on the buildings around the house — a workshop, a pole barn, a well house, a pump house, a stock gate, a trailer parked behind the treeline. These have their own failure pattern, and it is not the one that affects a front door.

Outbuilding hardware lives outdoors permanently, is used irregularly, and is almost always the cheapest thing that was to hand when it went up. Padlocks are the biggest offender. A low-grade padlock hanging on a gate for two or three seasons seizes in its own body — moisture wicks in, the shackle spring corrodes, and the mechanism gums up with dust and pollen until no key will turn it. Once seized, it is cut off; nothing sprayed into it brings it back. The practical answer is a weather-rated padlock with a shielded or fully enclosed shackle, dry-lubricated once or twice a year, and keyed alike with the others on the property so one key runs the whole place instead of a ring of twelve.

Hasps deserve as much attention as the padlock hanging from them. A quality padlock bolted through a soft hasp with exposed screws is a hasp problem, not a lock problem. The staple should be through-bolted, and the fasteners should not be reachable when the hasp is closed.

Gates and long driveways are the other common item. The lock is rarely what fails first — the post has shifted in soft ground, the gate has dropped on its hinge, and the latch no longer meets its keeper. Realigning the gate is what makes the lock work again. On a property with more than one gate, keying them alike is the difference between an errand and an ordeal.

The one thing worth planning rather than improvising is key management across a property with many buildings. Rather than accumulating a key per building over the years, a set keyed alike, or a small master arrangement where individual buildings have their own key and one master runs everything, turns access from a memory test into a system.

What to have ready when you call

Tell us the age of the house if you know it, and whether the hardware looks original. Say whether the lock is a knob or lever with a separate deadbolt, or a single unit with a handle and a keyhole in the same plate — that last description usually means a mortise case, and it changes what comes off the truck. Say whether the key is a flat modern key or a barrel-shaped one. If a door has been sticking, say for how long and whether it changed with the season. If a key broke, leave the fragment where it is and say so. For an outbuilding, tell us whether the padlock still accepts the key and simply will not turn, or whether the key no longer goes in at all — those are different problems.

More straight answers

Can my original hardware be saved, or do I need new locks?

In most cases it can be serviced. Broken springs, worn spindles and dirty lever packs are repairable, and the case usually stays in the door. Replacement is the right answer when a case is cracked or a part no longer exists, and you should be told which of those applies before anything is removed.

My key stopped working in a lock that has been fine for years.

Look at the key first. Worn brass is the most common cause of a lock that suddenly becomes unreliable. If a different copy works consistently, that confirms it, and a key cut to the code fixes it.

Can I put a modern deadbolt on an antique door?

Often, yes, and it is frequently the right call on an exterior door. What matters is where it goes and how much material is removed. Boring a new hole through an old stile in the wrong place weakens the door permanently, so placement is a decision to make carefully rather than at speed.

My padlock will not turn any more.

If the key goes in and will not move, the internals have seized and the lock is finished. It gets cut off and replaced. Fit a weather-rated one and dry-lubricate it on a schedule, and consider keying the whole property alike while somebody is already there.

The deadbolt only throws when I lift the door.

The door has moved, not the lock. Throw the bolt with the door standing open to confirm — smooth open and stiff closed means hinges and strike, not hardware.
