What counts as lock installation, and when do you need it?
Lock installation means fitting a lock into a door that has none, or fitting new hardware where the old set has reached the end of its life. The work is more than screwing a box-store lock into a pre-drilled hole. It is boring and chiseling to the right dimensions, setting the latch and strike so the door closes without a fight, and checking that the key turns smoothly with the door shut, not just on the workbench.
It helps to know what installation is not. If your lock works but you are worried about who holds copies of the key, you probably want lock rekeying, where the lock stays on the door and only the internal pins change. That is usually the more economical route. If one lock has failed and you want the same kind of hardware back in the same hole, that falls under lock replacement. This page is about the cases where something new is going into a door: a new home, a new door, a new opening, a change in lock type, or an upgrade in security level.
People in Fillmore call us for new lock installation for a handful of recurring reasons: a newly built home that needs its hardware set up the way the owner wants it, a remodel with a new door slab, a shed or workshop door that never had a real lock, a rental that needs consistent hardware, or a business opening its doors. Sometimes the trigger is simpler. A knob that never latched right finally quits, and the owner decides to put in something better rather than patch it again.
One more point we say often: a lock that fits in the package is not the same as a lock that is fitted. A latch that is a few millimeters out of line will drag, wear, and eventually fail, and a strike plate set slightly wrong can leave a door that looks locked but can be pushed open. Getting those small dimensions right is most of what you are paying a tradesperson for.
Which types of locks do we install?
We install most of what a home or small business needs. Because the right lock depends on the door and the use, we usually ask a few questions before recommending anything: how thick is the door, what is it made of, who needs keys, and how much punishment will it take.
- Front door lock installation: keyed entry sets, handle sets with a separate deadbolt, and single-cylinder or double-cylinder arrangements where the door and local fire-safety considerations allow.
- Lever lock installation: lever-handle locksets for interior and exterior doors, often chosen for easier grip and for accessibility. Levers are common on commercial doors and increasingly on homes.
- Mortise lock installation: the heavier, rectangular-bodied lock that sits in a pocket cut into the edge of the door, found on older homes and many storefronts. We can fit new mortise locks and work with the existing pocket where it is sound.
- Security lock installation: higher-grade deadbolts and locks with stronger cylinders, longer throws, and reinforced strikes. For picking- and drill-resistant options, see our page on high security locks.
- Residential lock installation: knobs, levers, deadbolts, and combination sets for entry, garage service doors, side gates attached to the house, and patio doors.
- Commercial lock installation: grade-rated hardware for shop doors, back doors, and offices, including keyed-alike sets so a business owner carries one key rather than a ring of them.
- Electronic and keypad locks: we can fit these too, but they have their own considerations, so they are covered on our smart lock installation page.

Call (213) 577-1366How does a lock installation go, step by step?
Every door is a little different, but the process we follow is the same. It is built around catching problems before the lock goes in rather than after.
- We start with a conversation about the door and the goal. You tell us what you are trying to secure, who needs access, and any past problems like a door that sticks or a lock that was forced.
- We inspect the door, frame, and jamb. We look at door thickness, material, and condition; whether the frame is solid or soft; and whether the existing holes and pockets are usable. A new lock in a split or rotted frame is only as strong as the wood around it.
- We recommend hardware and explain the trade-offs plainly. That might mean a standard-grade lock where the door is lightly used, or a heavier lock where the door faces an alley or an unattended outbuilding. If you already bought the hardware, we will tell you honestly whether it suits that door.
- We prepare the door. This can mean drilling a new bore, cutting a latch mortise, or enlarging or filling existing holes so the lock sits firmly. Where the frame is weak, we reinforce the strike area with longer screws or a proper strike plate set into solid material.
- We fit the lock and set the latch and strike. The latch should enter the strike freely with the door closing normally, and the bolt should throw fully without binding.
- We test everything with the door closed, open, and under normal use. Keys are cycled several times, the handle or lever is checked for return and smoothness, and we check that the door still latches in hot-weather conditions if it is a wood door that moves with the seasons.
- We hand over the keys and explain how to look after the lock, including what to do and what to avoid when a mechanism starts to feel stiff.
What affects the cost of lock installation in Fillmore?
We do not publish flat numbers for installation, because the same job title can mean very different amounts of work. What we can do is tell you exactly what moves the cost up or down so there are no surprises.
The lock itself is the first factor. A basic entry set and a high-security deadbolt are different products at very different ranges, and mortise locks generally cost more than bored cylindrical locks, both for the hardware and for the labor. The second factor is door preparation. A door already bored for a standard lock is a lighter job; a door that needs new holes, a new mortise pocket, or repair of damaged edges takes more time. Door material matters, too. Solid wood, hollow-core, metal, and glass doors each need different tooling and care.
The number of locks is the third factor. Several doors keyed alike, or a set of exterior doors done together, often makes more sense in one visit than several. Fourth is the frame. If the jamb is damaged, we may need to reinforce it, and we will tell you before we start. Last is timing and travel. Fillmore is roughly 55 miles from our Westwood storefront, so planned installations are scheduled so that we arrive with the right hardware and tools, and after-hours or urgent calls are handled differently from a scheduled appointment.
If you describe the doors and the type of lock over the phone at (213) 577-1366, we can usually explain which of these factors apply to your job before anyone drives out.

Call (213) 577-1366Why does the door matter as much as the lock in Fillmore?
Fillmore sits inland in the Santa Clara River Valley, with hot, dry summers and occasional strong downslope winds. Both affect how a newly installed lock behaves over the years, and we plan the installation around them.
Summer heat can swell wood doors and frames, particularly in older homes. A lock that is set with no allowance for that movement can bind in August and loosen in winter. We check clearances with that in mind and avoid fitting parts so tightly that a hot week turns a smooth deadbolt into a stubborn one. If your door already sticks in the heat, we will tell you whether that is something the installation can fix or whether the door itself needs planing or adjustment first.
Valley dust is the other factor. Fine dust works its way into exterior lock mechanisms over time, and it tends to do the most harm in cylinders that are exposed on a porch or a gate. That is one reason we pay attention to where a lock is mounted and which hardware is suitable for an exposed position. A lock on a sheltered interior door and one on a gate beside a dirt drive do not face the same conditions, and the best choice for each is different.
None of this is complicated, but it separates an installation that feels good on day one from one that still feels good in five years.
What does lock installation look like around Fillmore?
Fillmore is a small, mostly single-family city, and the lock work follows the housing. Our work here usually falls into a few patterns, and the neighborhoods you live in tend to point to the right approach.
In Heritage Grove on the north side, the homes are newer tract construction, and installation questions there tend to come from new owners. A common scenario is rekeying new tract homes in Heritage Grove, where the question is whether the builder's hardware is worth keeping or whether it should be upgraded. Where owners want a stronger front door lock installation, a better deadbolt, or lever sets that match throughout the house, we install them to suit the existing door preparation, which is usually standard and straightforward. For simply changing who holds the keys, rekeying is often enough and is the lighter-cost option.
Near downtown, around the Central Avenue district, the housing is early-1900s bungalows and 1920s to 1940s cottages. These homes often have vintage hardware, thick wood doors, and older frames that have moved over decades. Installing a new lock there is a different job from installing one in a recent tract house. We may need to work around an existing mortise pocket, choose hardware whose faceplate matches the old cutout, or reinforce a frame that has dried and softened. If you are putting a new lock into a bungalow door, we look first at what the door can accept without being damaged.
North Fillmore and the postwar single-family streets around the core fall between the two. Doors there are usually standard sizes, but they have had decades to wear, and we often find old locks that were replaced once and never fitted properly. The ZIP code 93015 covers all of this area, and the same approach carries across it: inspect, fit, test.
Outside town, near Bardsdale and Piru, which are close by but unincorporated, and across the valley floor, citrus ranch properties have outbuildings, sheds, and gates. These need locks that hold up outdoors, and often different lock types than a house door. New outbuilding doors may need a hasp or a deadbolt fitted into a rough frame, and gate locks have their own challenges, which we cover on our gate lock repair page. Because we serve 140 cities across Los Angeles and Ventura counties, travelling to rural Fillmore properties is routine for us, though we do plan the trip carefully given the distance from our Westwood base.

Call (213) 577-1366What about commercial lock installation on Central Avenue?
Businesses in Fillmore, especially along Central Avenue, have different installation needs from homes. A shop door gets used constantly, often by several people, and it faces the street. Commercial lock installation usually means choosing hardware rated for heavier use, fitting levers or mortise locks in storefront doors, and coordinating keys so staff can open and close without a heavy ring.
We handle new installations for shops, offices, and back doors, and our commercial locksmith page covers the broader range of business work. If you have an existing storefront lock that is failing rather than a new opening that needs hardware, storefront lock repair is the better starting point, and we will tell you honestly whether repair or fresh installation makes more sense for that door.
One thing worth saying about older commercial buildings: the doors and frames are sometimes unusual, and standard hardware does not always fit. We measure first and tell you what will work, rather than forcing a lock in and hoping.
Why call Wilshire Lock & Key for installation?
We have been in business since 1987, and installation is one of the oldest parts of the trade. We are a real storefront at 10740 Wilshire Blvd in Westwood, with mobile service vans that come to you. When you call (213) 577-1366, you are speaking with our own company, not a call center that passes your job to whichever contractor is free. There are no dispatch middlemen between you and the person doing the work.
David, the owner and lead technician, oversees how our jobs are done, and the standards he set decades ago are the ones still in use. That includes a habit we think matters: we test every lock on the actual door before we leave, and we tell you if we see a problem we were not asked about, such as a loose frame or a lock that does not suit its door.
We answer the phone around the clock, every day of the year, so if you discover a door will not secure at night, you can reach us. Installation is often planned work, but not always. A forced door, a burglary, or a move-in the night before can mean you need a lock fitted urgently, and we handle that too.
How should you choose a lock, and what should you ask any locksmith?
Start with the door and the risk. A bedroom or a hall closet does not need the same lock as a front door, and a garden shed is not the same as a back door that opens to an alley. A reasonable approach is to put the most attention on the doors someone would actually try, and to match the lock to the door rather than the other way around. A strong deadbolt in a weak frame is a common mistake, which is why we look at the frame before we recommend hardware. If a deadbolt is the main thing you need, see our deadbolt installation page.
Ask any locksmith, including us, about licensing. California requires locksmith companies to hold a license from the Bureau of Security and Investigative Services, called a BSIS LCO license, and you are entitled to ask for it before work starts. You should also ask who will actually do the work and whether they will test the lock on the door before they leave. Be careful with anyone who quotes a surprisingly specific figure without asking about the door, because lock installation depends on conditions that cannot be known until someone has seen it or at least heard a good description.
Finally, keep your keys organized. When we install, we label what each key opens and tell you how many we have cut, so you know who holds copies. If a new home or business is changing hands, that single step prevents many of the problems people call us about later.
Frequently asked questions
How long does a lock installation take?
It depends on the door. A standard lock going into a door that is already bored is a short job. A new bore, a mortise pocket, or a repair to the frame takes longer. When you call (213) 577-1366 and describe the door, we can tell you which kind of job it probably is.
Can you install a lock I already bought?
Often yes. We will check that it suits the door and the use before we start, and we will tell you plainly if it is the wrong thickness, the wrong backset, or too light for the door. We cannot always vouch for hardware we did not supply, so we will explain what we see.
Can you install a mortise lock in an older Fillmore bungalow?
Yes, in many cases. Older doors near downtown often already have a mortise pocket, and we can fit a new mortise lock to it or work with the old cutout. If the pocket or the door edge is damaged, we will say so before cutting anything. Matching vintage faceplates can take extra care.
Will a newly installed lock use the same key as my other locks?
Sometimes. If the new lock is from a compatible brand and keyway, we can often key it to match your existing locks, so you carry one key. If the hardware is different, we may need to match the key some other way or key all the locks to a new key. We will explain which applies.
Do you install locks on shop doors and outbuildings, not just houses?
Yes. We handle commercial lock installation for storefronts, offices, and back doors, and we install locks on sheds, workshops, and outbuildings, including those on ranch properties around Fillmore. The hardware choice differs from a house door because of weather, dust, and use.
My wood door sticks in summer. Will a new lock fix that?
Not by itself. Heat can swell wood doors and frames, and a lock cannot correct that movement. We check whether the problem is the door fitting the frame, and we set the new lock so that it does not bind in hot weather. If the door needs adjusting, we will tell you.
Do you only do new installations, or can you also rekey what I have?
We do both. If your existing locks are sound and the issue is who has keys, rekeying is usually the lighter-cost route. If the hardware is worn, the wrong grade, or missing, installation makes more sense. We would rather tell you which is which than sell you something you do not need.
Is your company licensed to do lock installation?
California requires locksmith companies to hold a BSIS LCO license, and you should ask any locksmith for it, including us, before work begins. Our license number is being added to this site, so please ask when you call (213) 577-1366 and we will answer directly.
