What does lock installation in Lomita actually involve?
Putting a new lock on a door sounds simple until the door says otherwise. A lock has to match the thickness of the door, the size and position of the bore holes, the backset (the distance from the edge of the door to the center of the lock), the edge preparation, and the strike plate in the frame. If any one of those is slightly off, the lock may still go in, but it will bind, rattle, drag against the frame, or fail to throw the bolt all the way into the jamb. That is the difference between installing a lock and installing it correctly.
Wilshire Lock & Key has been doing this work since 1987. We run a storefront at 10740 Wilshire Blvd in Westwood and send mobile service vans out to customers across 140 cities in Los Angeles and Ventura counties, Lomita included. This page is about fitting new locks on doors: front doors, back doors, garage side doors, shop doors, and interior doors that need a lock they never had.
If what you really have is a lock that already exists but has failed or worn out, that is a different job, and we cover it on our lock replacement page. If the hardware is fine and you only need different keys, lock rekeying is usually the more economical route. Installation is for the situations where a door needs new hardware, or hardware it never had.
When does a door need a new lock installed?
Most installation calls fall into a handful of situations. Knowing which one you are in helps us bring the right hardware on the first trip, which saves you a second visit.
- A door has no lock at all, such as a new addition, a converted garage, a workshop, or an interior door that now needs privacy or security.
- You are upgrading from a basic knob lock to something stronger, like a quality deadbolt or a higher-grade lever set.
- A remodel or new door is going in and the hardware has to be fitted to the new slab and frame.
- A door was cut for hardware that no longer exists, and the old bore pattern needs a lock that suits it.
- A break-in attempt left the door or latch damaged and you want a better lock fitted at the same time as the repair.
- A commercial space is opening or changing tenants and the entry doors need proper hardware before the first day of business.
- You want a keypad or electronic lock in place of a keyed one. We cover that separately on our smart lock installation page.

Call (213) 577-1366How do we install a lock, step by step?
The process below is how a typical installation goes. Every door is a little different, so the order can shift, but we do not skip the checking steps at the start or the end.
- We talk through the door first. On the phone, we ask what kind of door it is (wood, hollow metal, solid core, aluminum storefront, mobile home door), what lock is on it now if any, and what you want the lock to do. That lets us bring suitable hardware.
- We inspect the door and frame on arrival. We measure thickness, check the bore holes and backset, look at the edge, and look at the condition of the jamb. A lock is only as solid as what it screws into.
- We confirm the hardware with you before cutting or drilling anything. If the door calls for a different lock than you expected, we explain why and give you the options.
- We prepare the door. If holes or edge mortises need to be cut, we use proper jigs and bits so they are clean and square. If an existing bore needs adjusting, we do that with the least damage to the door.
- We fit the lock body, latch, and trim, then install the strike plate in the frame. On deadbolts and security locks, we use long screws that reach the stud rather than just the thin jamb.
- We align and test. The bolt should throw smoothly and fully, the latch should catch without lifting or pushing the door, and the key should turn without force. We test with the door open and closed.
- We hand over the keys, show you how the lock operates, and clean up the shavings and packaging. If you want more copies later, our key duplication service is available.
What types of locks do we install?
Different doors want different locks. Here is how we think about the main categories, without the brochure language.
Front door lock installation is usually a combination: a latch set or lever on the handle side and a deadbolt above it. The handle keeps the door closed, and the deadbolt is what actually resists force. A front door should almost always have both working properly, and the deadbolt should have a strike plate that is anchored well.
Door lock installation on a back or side door follows the same logic, but these doors are often less visible from the street, which is exactly why they deserve the same attention as the front. We also handle sliding and patio doors where the hardware is different, and we will tell you plainly if a particular door is better served by a secondary bar or pin than by a lock alone.
Mortise lock installation is a different animal. A mortise lock sits inside a deep pocket cut into the edge of the door, rather than in two round holes. It is common on older buildings and on many commercial doors, and it is strong when done well. Installing one means cutting or reusing a precise pocket, so this is work we slow down for. If a door already has a mortise pocket, the replacement lock must match its dimensions.
Lever lock installation covers the handles you press down instead of twisting. They are popular for commercial doors and for homes where easy operation matters, because they are friendlier for hands that struggle with a round knob. Levers come in different grades, and the grade matters more on a door used all day.
Security lock installation is about picking hardware that resists picking, drilling, and forced entry beyond the basics. That can mean a higher-grade deadbolt, a reinforced strike, or a restricted keyway. We go deeper on that on our high security locks page.

Call (213) 577-1366Residential or commercial: does the installation differ?
Yes, in a few important ways. Residential lock installation is mostly about the right balance of security and convenience on wood or solid-core doors, with attention to appearance, since the hardware is part of how the home looks. Keys, finish, and style matter to homeowners, and we take those into account.
Commercial lock installation puts heavier demands on the hardware. A shop door is opened and closed many times a day, sometimes with deliveries, sometimes by staff with different access levels. The lock needs to be a commercial grade that handles the traffic, and the door may need a closer, a panic device, or a specific function such as storeroom or office. Commercial doors are often aluminum or hollow metal, which means different prep and different fasteners than a wooden house door. We discuss the full range on our commercial door hardware page.
Fire codes and egress rules can also apply to commercial doors, so the lock function is not always a free choice. If you are not sure what your door requires, ask us before you buy hardware online. A lock that looks right but has the wrong function can cause problems later.
How much does lock installation cost in Lomita?
We do not quote prices on a web page, because the honest answer depends on the door. What we can do is tell you what moves the cost up or down, so you are not surprised.
- The lock itself. A basic latch set, a quality deadbolt, a commercial-grade lever, and a mortise lock sit in very different places, and the grade of the hardware is the largest single factor.
- The condition of the door. A door that is already bored for the lock is quick work. A door that needs new holes cut, an edge prepared, or a mortise pocket formed takes more time and skill.
- The frame. If the jamb is split, soft, or badly aligned, the strike plate cannot do its job, and fixing that is part of a real installation.
- The number of locks. Keying several doors alike, or fitting a full set for a house, changes how the job is planned.
- Door material. Wood, solid core, hollow metal, aluminum, and mobile home doors each have their own preparation needs.
- Timing and location. Work outside normal hours or at a greater distance from our base can affect the final figure.
- Extras such as restricted keys, reinforcement plates, or matching existing keys to a new lock.

Call (213) 577-1366What should you know about lock installation around Lomita?
Lomita has a small-town mix of housing, and each type asks something different of a new lock. Many homes are 1940s and 1950s cottages and ranch houses, often on deep lots left over from the city's small-farm days. On older wood doors, we pay attention to how the door has aged. Lomita sits at the foot of the Palos Verdes Peninsula a couple of miles from the water. The marine layer brings damp air with only mild salt exposure, and older wood doors commonly swell in the damp months. A new lock fitted tight to a swollen door can bind or stop latching. We check the door's fit before and after, and we leave a sensible margin so the hardware works through the seasons. Our mobile locksmith vans bring the tools to do that on site.
Homes on those deep lots often have more than one door to think about: a rear door, a side gate entry, and a detached garage or workshop. Adding or upgrading locks on those outbuildings is a common request, and it is usually worth fitting them at the same time as the house doors so the whole property is consistent.
Along the Pacific Coast Highway corridor, several mobile home parks sit along and near PCH. Installing a lock on a mobile home door is not the same as a standard house job. These doors can be lighter and their bore patterns do not always match what you would find at a hardware store, so we check measurements before we promise a particular lock. Near the Narbonne Avenue corridor and the PCH and Narbonne intersection, small apartment buildings and storefronts cluster together, and the work shifts between residential doors and commercial-style hardware for shops. Further along the Lomita Boulevard corridor, you will find a mix of homes and townhome or condo infill, where an HOA may have rules about which lock finish or type you can fit on a front door. Check with your HOA before you choose hardware.
We also work in the surrounding areas that Lomita residents often mean when they give their address, such as near Harbor Hills, near Walteria in Torrance, and near Harbor City. Whatever the ZIP, 90717 for Lomita itself, the approach is the same: we look at the actual door before deciding what goes on it. Lomita is roughly 24 miles from our Westwood base, which is why we send mobile vans rather than asking you to bring the door to us.

- Our phone is answered 24 hours a day, 7 days a week, year-round at (213) 577-1366. If a door will not secure at night, you do not have to wait for morning.
- We explain what we find and what the options are, including when a cheaper fix is the right one.
What should you ask any locksmith before they start?
California requires locksmith companies to hold a license from the Bureau of Security and Investigative Services, known as a BSIS LCO license. You should ask any locksmith for their license number before work starts, and you can check it with the state. This is good practice with any company, including us.
Beyond the license, ask what lock they plan to fit and what grade it is, whether the quote covers the whole job including the strike and any door prep, and who will actually come to your door. A clear answer to those questions tells you most of what you need to know. If you are still deciding, the best first step is a call to (213) 577-1366, where we can talk through your door, or you can visit our Lomita service page for an overview of what we offer in the city.
Frequently asked questions
Can you install a lock on a door that has never had one?
Yes. We measure the door, cut the holes and any edge preparation with proper jigs, fit the lock, and install the strike in the frame. We check the door thickness and frame condition first so the new lock sits solidly and operates smoothly.
Is a deadbolt part of lock installation, or a separate service?
A deadbolt is one of the lock types we install, and we handle it as part of front and back door work. If a deadbolt is all you need, our dedicated deadbolt installation page explains how that job goes.
Do you install locks on mobile home doors in Lomita?
We do. Mobile home doors can be lighter than house doors and their bore patterns vary, so we check the measurements before choosing hardware. If you can tell us the door type and what is on it now, that helps us bring the right lock.
What is the difference between a mortise lock and a regular door lock?
A regular lock sits in round holes through the door and edge. A mortise lock sits inside a deep rectangular pocket cut into the edge of the door. Mortise locks are common on older and commercial doors, and a replacement has to match the existing pocket.
Will a new lock work on my older wood door that swells in damp weather?
Usually yes, but the fit matters. Older wood doors in the Lomita area commonly swell in damp months, so we check the door's alignment and leave a sensible margin so the latch and bolt do not bind when the weather changes.
Can you install commercial locks for a shop on Pacific Coast Highway or Narbonne Avenue?
Yes. We fit commercial-grade locks on storefront and office doors, and we can advise on function, door closers, and exit hardware where needed. For problems with existing storefront hardware, see our storefront lock repair page.
How do I know what type of lock my door needs?
Tell us about the door: material, thickness, whether it is already drilled, and how you use it. We will recommend the lock type and grade, and confirm in person before any cutting or drilling takes place.
Do you install locks at night or on weekends?
Our phone line at (213) 577-1366 is answered 24 hours a day, 7 days a week, year-round. If a door cannot be secured, call any time and we will work out the next step with you.
