Mid-Century Homes and the Hardware They Came With
The neighborhoods east of downtown Orlando, including the area around Lake Underhill, contain many homes built in the middle of the twentieth century. These are often single-story houses with low rooflines, concrete block or wood frame walls, jalousie or aluminum windows and front doors set under a small overhang. They have been remodeled, added onto and repaired many times. Few still have every original part, but many keep some of the old hardware.
Old hardware has charm and a few problems. Early cylindrical knob sets were designed for a time when a house was left unlocked more often than not. Their latches are short, their strike plates are thin and their keyways are simple. Over decades the springs soften, the screws loosen in the soft wood and the plating wears through to bare brass. A lock may still turn but give little resistance to anyone who leans on the door.
A technician visiting such a house looks first at what can be saved. A sound lock body often needs only a new cylinder or a rekey. A loose latch can be tightened. A worn strike can be replaced with a longer, sturdier one. Replacing everything is sometimes the right answer, but it is not the only one, and a phone call can help sort out which approach fits the door in front of you.
Doors That Have Shifted Over Time
Houses settle. Wood swells in the wet season and shrinks in the dry. Hinges loosen. After fifty or sixty years, a door that once fit its frame precisely may now rub at the top corner, gap at the bottom or sit crooked. The lock may be perfectly sound while the door no longer lines up with it.
The symptoms are familiar. You must lift the door while turning the key. The deadbolt moves slowly or hits the frame. The latch does not click into the strike. The door has to be slammed to close. Many people blame the lock and replace it, only to find the problem remains. A technician who sees the whole door can often fix it by tightening hinge screws, shimming a hinge, enlarging the strike opening or moving the strike plate a fraction of an inch.
If the frame is rotted or split, particularly near the strike and the bolt, the repair becomes carpentry. A technician can reinforce a frame that is sound but weak, using a longer strike plate and long screws that reach the stud. A frame that is soft with rot needs a carpenter before any lock can hold. Our guide on door frame and hinge security explains why the frame matters as much as the lock.
Keeping Original Hardware Without Giving Up Security
Some owners love the look of original hardware and want to keep it. That is a reasonable wish, and a good technician will respect it. The best approach is often to leave the old hardware on the door and add a modern deadbolt above it. The old knob stays as a latch, and the new deadbolt provides the security. The result is a door that looks right and resists force better.
Mortise locks, which sit in a deep pocket cut into the edge of the door, appear in some older homes and in some commercial doors. They are sturdy but need experienced hands. Parts are not always easy to find, and a worn mortise lock may be better repaired than replaced. Our page on mortise lock service describes what is possible, and the historic home lock guide covers considerations for older houses.
Owners who want modern convenience in an older house can also choose a keypad deadbolt or smart lock, as long as the door has the standard bore or can be adapted. Do not drill a door yourself without knowing what is inside it. A technician can measure and tell you whether the door will accept a new lock or needs preparation first.
Rekeying After a Home Changes Hands
Mid-century homes in neighborhoods like this change owners regularly. People buy, renovate, sell and move on. Each transaction leaves behind keys: with former owners, agents, inspectors, contractors, cleaners and neighbors. After a purchase, nobody can say how many copies exist.
A rekey is the usual answer. The technician removes the cylinder from each lock, changes the pins to match a new key and reinstalls it. The lock body stays on the door, and the old key stops working. It is faster than replacing hardware and less disruptive to the door. In a house with several exterior doors, all can be keyed alike, so one key opens the front, the side and the back.
New owners should do this before moving in, or as soon as possible afterward. Inspect the doors at the same time, since a locksmith visit is a good moment to check the strike plates, the deadbolt throw and the window and slider locks. Our page on lock rekeying and the guide to moving-in security steps offer more.
Jalousie Windows, Aluminum Sliders and Window Locks
Older Florida homes often have windows that were designed for ventilation first and security second. Jalousie windows, with their slats of glass in a metal frame, let breezes in but offer little resistance. Aluminum sliders have small latches that can be lifted or forced. Over time, the tracks fill with dirt and the latches wear.
Upgrading a window lock is often simpler than owners expect. A secondary lock or a pin that stops the window from sliding open more than a few inches adds a degree of security without spoiling ventilation. A track bar on a sliding glass door has a similar effect. A technician can suggest measures that suit the window type. See window lock repair and sliding patio door locks for the usual options.
Think about the escape side as well. Bedroom windows are an emergency exit in a fire, and any lock added to one must be operable from the inside without a key. A lock that traps people in is a hazard, not a protection.
Carports, Side Doors and Detached Sheds
Homes of this era often have a carport rather than a garage, with a side door to a utility room and a shed in the back yard. The side door tends to be the weakest in the house, because it is out of sight from the street and rarely upgraded. A hollow-core door with a basic knob is common, and it offers little resistance.
A simple upgrade makes a difference. Replace the door with a solid one or reinforce the existing door around the lock. Add a deadbolt with a one-inch throw and a strike plate with long screws. If the door has glass near the lock, consider a double-cylinder deadbolt or a security film, though a double-cylinder lock needs a key on the inside and should be used with care because it can slow an exit in a fire.
Sheds and storage buildings hold tools, lawn equipment and sometimes bicycles. A padlock is the usual answer, and a good one with a shrouded shackle is harder to cut. If you lose a padlock key, a technician can open and replace the padlock. See padlock key lost for what to expect.
Lakeside Humidity, Shade and Slow Corrosion
A lakeside setting means a higher moisture level in the air, plus shade from mature trees that keeps surfaces damp. Door hardware here rarely dries out fully. Plated finishes lift, steel parts rust and cylinders fill with a sticky film of dust and moisture. You may notice a lock that is stiff in the morning and eases as the day warms.
Regular care helps. Wipe exterior hardware with a damp cloth and dry it. Apply a dry lubricant to the keyway once or twice a year. Do not use heavy oil, which collects dust. Tighten the screws on the knob and the strike plate. Trim any shrubs that rub against the door, since constant dampness near the frame speeds up rot.
If a lock is already rusted, it may be time to replace it. A technician can tell by looking at the cylinder and the bolt. Our page on lock rusted from salt and humidity explains the signs, and the guide to humidity and lock longevity adds tips.
Car Keys, Driveways and Street Parking
Many homes here have short driveways or parking along the street. A car lockout at home is common: the car locks behind you as you carry groceries inside and the keys are on the seat. A mobile locksmith can open the car at the curb. Most calls need only a short visit.
For lost keys, a technician needs the vehicle identification number, proof of ownership and photo identification. Newer cars use transponder keys or smart keys that must be programmed. Older cars from before the late 1990s may use a plain metal key that can be cut without programming. If you have a car from any era, say what it is and the technician will know what to bring.
If a key breaks off in a door or ignition, stop trying to turn it. Forcing can wedge the piece deeper. A technician has extractors made for this job. See broken key extraction and car key replacement for details.
Renters, Landlords and Duplex Owners
Not every home in the neighborhood is owner-occupied. Some are rented, some are duplexes and some have a back unit or an apartment above a garage. Landlords here face the usual question: how to give each tenant secure access while keeping control of the property.
The tools are the same as anywhere. Rekey between tenants. Use keyed-alike locks so a tenant carries one key. Keep a written record of who has which key. For an owner who lives elsewhere, a keypad deadbolt can let a property manager give access to a repair worker without handing over a key. See landlord lock responsibilities in Florida for general guidance, and consult an attorney for legal questions.
Tenants who find themselves locked out should contact the landlord first. If that fails, a locksmith can open the door once identity is confirmed, but should not change locks without the owner's approval.
How Quotes and Dispatch Work
Every price is given by phone before a technician is sent. The dispatcher asks about the lock, the door and the location, and explains the cost. For a simple lockout the quote can often be given right away. For complicated work, such as old mortise hardware, a damaged frame or several doors, an on-site visit may be needed first. A service call charge applies, and it is explained before dispatch.
On arrival, the technician introduces themselves, confirms your name and address and asks for identification. They explain the work, perform it and test the lock with you. Keep your receipt. See what to expect on a locksmith call and how a phone quote works for more.

If you are locked out, or if an old lock has begun to fail, call and describe the door, the lock and what happened. If anyone is in danger, call 911 first. Otherwise the dispatcher can tell you what to expect and give you a quote before anyone is sent. Have your address and identification ready when you call.
Questions people ask
Can an old knob lock be repaired instead of replaced?
Often yes. A worn cylinder can be replaced or rekeyed, a loose latch can be tightened and a thin strike plate can be swapped for a stronger one. Replacement makes sense when the body is damaged or the lock gives little security. A technician can look at it on site, and a phone call can give you a general idea first.
My door only locks if I lift it. Is the lock broken?
Probably not. The door has likely sagged on its hinges so the bolt no longer lines up with the strike. Tightening hinge screws, shimming a hinge or adjusting the strike plate often fixes it. If the frame is rotted around the lock, it needs repair first, since no lock can hold well in soft wood.
Can I keep my original hardware and still be secure?
In many cases, yes. A common approach is to leave the original knob as a latch and add a modern deadbolt above it with a long strike plate. The door keeps its look and gains resistance. A technician can check that the door and frame are strong enough to support the new lock.
We just bought the house. Should we change the locks?
It is a sensible step, since you cannot know how many keys exist. Rekeying is faster than replacing and changes the pins so old keys no longer work. Ask for keyed-alike locks so one key opens every exterior door. Do it before you move in, and check strike plates and window locks at the same visit.
Is it safe to put a lock on a bedroom window?
Only if it can be opened from the inside quickly without a key, since a bedroom window may be an escape route in a fire. Pins or secondary latches that release by hand are suitable. Avoid any lock that needs a key to open from the inside. A technician can suggest options that meet that need.
Describe the situation by phone and we will tell you what the job involves. Quotes are given by phone. Jobs that cannot be quoted without seeing them need a technician on site, and the service call charge is explained on the phone before anyone is dispatched.
