What does a proper lock installation involve?
Most people think installing a lock is a matter of dropping a new knob into an old hole. Sometimes it is. More often the job is about the door: its thickness, its bore holes, the edge prep, the strike plate, the frame behind it, and whether the wood is still sound enough to hold hardware under real use. A lock that is bolted into a tired door will feel fine for a week and then start to bind, rattle, or fail the first time someone leans a shoulder against it.
That is why we treat lock installation as door work as much as lock work. We look at what is there, decide what the door can carry, and fit the hardware so it turns freely, latches cleanly, and throws a deadbolt fully into a solid strike. When the existing door prep does not suit the lock you want, we say so and explain the options before we cut anything.
This page covers fitting new locks where there is no working lock, where you are adding a second one, or where you are upgrading to a different type. If an existing lock is simply worn out and you want it swapped, our lock replacement service is the closer match, and if you only need new keys for locks you already trust, rekeying is usually the more economical route.
Which kinds of locks do we install in Hermosa Beach?
Hermosa Beach has a wide mix of doors, from small cottage entries to townhome front doors to commercial glass and steel. We install the hardware that fits each of them, and we will tell you plainly when a different lock would serve you better than the one you first had in mind.
- Front door lock installation: entry knobs, lever handlesets, and keyed entry sets matched to the door's thickness and bore size.
- Door lock installation for interior and secondary doors: privacy sets, storage rooms, offices, and side doors.
- Deadbolt installation: single-cylinder and double-cylinder deadbolts, fitted square to the edge and aligned with a properly reinforced strike. See our separate deadbolt installation page for that service on its own.
- Mortise lock installation: the heavier, boxed lock bodies found in older wood doors and many commercial entries, which sit in a pocket cut into the door's edge.
- Lever lock installation: lever-handle locksets for residential and commercial doors, including sets chosen for easier grip.
- Security lock installation: higher-grade cylinders and hardware for doors that need more resistance to picking, drilling, and forced entry. More on that under high-security locks.
- Residential and commercial lock installation: the same trade, but commercial work adds code, door-traffic, and keying considerations.

Call (213) 577-1366How does a lock installation go, step by step?
We follow the same sequence whether it is a single deadbolt on a cottage door or several sets on a small building. The order matters, because shortcuts early on show up later as sticking, misalignment, or a lock that never quite feels right.
- You call (213) 577-1366, day or night, and describe the door: material, existing hardware, what you want installed, and whether this is a home or a business.
- We confirm what we can over the phone, tell you what affects the cost for your situation, and send a technician in a mobile van, or you can come to our Westwood storefront for hardware that does not need a visit.
- On arrival we inspect the door, frame, and strike area. We check thickness, backset (commonly 2-3/8 or 2-3/4 inches), bore size, edge condition, and whether the wood or metal is sound.
- We agree on the hardware with you. If the door needs reinforcement or the lock you chose will not suit the door, we explain that before starting.
- We prepare the door: new bores or edge cuts where needed, clean-up of old ones, and correct alignment so the latch and bolt line up with the frame.
- We mount the lock, fit the strike plate, and use longer screws into the framing where the situation calls for it, so the bolt is anchored into more than trim.
- We test every function with the door open and closed, adjust until it operates smoothly, and cut or set the keys. You leave with working keys and an explanation of how the lock is meant to be used and maintained.
What affects the cost of lock installation?
We do not quote numbers on a web page, because honest pricing depends on things we have to see or hear about first. Here is what actually moves the cost of a lock installation up or down.
The biggest factor is the hardware itself. A basic entry knobset, a Grade 1 commercial lever, a mortise lock body, and a high-security cylinder sit in very different places. Grade ratings, cylinder quality, finish, and brand all matter, and finish matters more than people expect near the ocean.
The second factor is door preparation. A door that already has the right bores and edge cut is straightforward. A door that needs new holes, patching of old ones, or reinforcement takes more time and sometimes extra materials. Mortise work in particular requires more skilled cutting than a standard bored lock.
Third, the number of locks and whether they should be keyed alike. Several locks on one key are convenient, but they require planning at the start, and they can be cleaner to do in one visit than piecemeal.
Finally, the setting. Commercial doors, glass doors with narrow stiles, and doors needing code-related hardware add complexity. Time of day and location can also factor in, since after-hours calls take a technician out of their regular schedule. We would rather explain all of this up front than surprise you at the door.

Call (213) 577-1366Mortise, lever, and security locks: when the lock type changes the job
Mortise lock installation is the one customers are most often surprised by. A mortise lock is not screwed onto the surface of a door like a typical bored lockset; the lock body sits inside a deep pocket cut into the door edge. If an old mortise pocket is there, the right lock body can often be fitted into it. If it is not, cutting a new one properly takes care, and on a door that is thin or already weakened, we may recommend a different approach.
Lever lock installation is usually more straightforward, but the details still count. Lever handles put more leverage on the latch and the door prep, so a loose or poorly supported set will wear out faster than a knob. On commercial doors we match lever sets to the door's use and, where it applies, to accessibility needs.
Security lock installation is about the whole assembly rather than just a bolt. A strong cylinder does little good if the strike is held by short screws into thin trim, or if the door itself can be flexed away from the frame. We look at the cylinder, the bolt throw, the strike, the hinges, and the frame together, then recommend what makes sense for the actual risk at your door. If you are curious about smart or keyless options, we handle those separately under smart lock installation.
What should Hermosa Beach homes and rentals know about lock installation?
Hermosa Beach is under 1.5 square miles, densely built, and sits within a few blocks of the ocean. That shapes the work. Much of the housing is small-lot beach cottages from the 1920s onward, many converted or rebuilt as multi-story townhomes, with duplexes, triplexes and small apartment buildings common in the Sand Section and along the Pacific Coast Highway and Aviation Boulevard corridors. There is a high share of renters and frequent unit turnover.
Salt air is the first thing to plan around. Exterior locks, hinges and gate hardware corrode routinely here, so a beachfront unit often needs a lockset replaced with something finished to resist it. When we install a new exterior lock on a door in the Sand Section or near Pier Plaza, we pay attention to finish and to the fasteners, because a good lock with a corroding screw will still fail. Marine layer damp also swells older wood-frame doors, which can make a new deadbolt bind if the door is not aligned properly during installation.
For owners of duplexes and triplexes in the Sand Section, East Hermosa and North Hermosa, installation often comes up when a unit has no lock worth keeping, a door has been replaced, or a new entry has been added in a remodel. If a unit just needs new keys after a tenant moves out, rekeying is the lighter-cost option; our locksmith for landlords page covers turnover work in more detail.
We serve all of 90254, and because many homes near the beach sit on walk streets or alley access, we plan for carrying tools and hardware on foot when the van cannot pull up to the door. Hermosa Beach is about 19 miles from our Westwood base, and our mobile vans are equipped to complete the installation on site rather than making a second trip for a missing part.

Call (213) 577-1366Commercial lock installation around Pier Plaza and the corridors
Bars, restaurants, and shops in Pier Plaza and Downtown, along with businesses on the PCH and Aviation Boulevard corridors, have different needs than a home. Doors open and close all day, entries are exposed to salt air and foot traffic, and fire and exit rules affect what hardware is allowed on certain doors.
Commercial lock installation means choosing hardware rated for the door's use, fitting it so it holds up under heavy cycling, and keying it in a way that makes sense for staff turnover. For restaurants and bars, that can include exit hardware on rear and side doors; our panic bar installation service covers that specifically. We keep this page focused on the locks themselves, and we will tell you if a door needs closers, exit devices, or other hardware as part of the same job.
Why call Wilshire Lock & Key for installation?
We have been in business since 1987, and we serve 140 cities across Los Angeles and Ventura counties, Hermosa Beach among them. In that time we have fitted locks on just about every kind of door you can find in a coastal city, from old wood cottage doors to commercial glass.
We are one company. When you call (213) 577-1366, you reach us, not a dispatch middleman who sells your job to whoever is closest. We have a storefront at 10740 Wilshire Blvd in Westwood for hardware and keys, plus mobile service vans that bring the work to your door. The phone is answered 24 hours a day, 7 days a week, year-round.
David, the owner and lead technician, oversees the work. That matters on installation, because fit and alignment are judgment calls, and they are best made by someone who has done thousands of them. If you prefer to have a technician come to you rather than visit the shop, see how our mobile locksmith service works.
How can you check a locksmith before you hire?
California requires locksmith companies to hold a license from the Bureau of Security and Investigative Services (BSIS), known as an LCO license. Ask any locksmith for their license number before work starts, and check it with the state. You should also expect a clear explanation of what is being installed and what factors affect the cost before anyone drills into your door.
Good signs include a technician who looks at the door before quoting, explains the hardware choice, and does not push a full replacement when a smaller fix would do. Be cautious of anyone who cannot tell you who they work for or who refuses to explain what drives the cost.
Frequently asked questions
Can you install a lock on a door that has never had one?
Yes. We prepare the door with the correct bores and edge cut, fit the latch and strike, and test the lock. We will also check whether the door and frame are solid enough to support the hardware before we begin.
What is the difference between lock installation and lock replacement?
Installation is fitting a lock where none exists, adding a second lock, or changing to a different type that needs new door prep. Replacement swaps a worn or damaged lock for a similar one. If you are not sure which applies, call (213) 577-1366 and we will help sort it out.
Do you install mortise locks?
Yes. If your door already has a mortise pocket, we can often fit a suitable new lock body into it. If a pocket needs to be cut, we will check that the door is thick and sound enough to take it before we start.
Will salt air affect a new lock?
It can. Hermosa Beach sits within a few blocks of the ocean, and salt-air corrosion of exterior locks, hinges and gate hardware is routine. We pay attention to the finish and fasteners we use on exterior doors so the installation holds up better in that environment.
Can you install locks on a commercial door in Hermosa Beach?
Yes. We fit commercial locksets, lever locks, and security hardware on storefronts and business doors. If the door also needs exit hardware, we can handle that as a related job.
How much will lock installation cost?
It depends on the hardware, the condition of the door, how many locks you want, whether they should be keyed alike, and the setting. We do not give numbers on the website, but we will explain exactly what applies to your door before work begins.
Do you come to me, or do I bring the door to you?
Both are possible. Our mobile vans come to your home or business anywhere we serve, and our Westwood storefront at 10740 Wilshire Blvd is open to those who want to pick up hardware or keys. Call (213) 577-1366 to arrange either.
Do I have to be home during the installation?
Someone should be there, at least at the start and the end, so we can confirm what is being installed, test it with you, and hand over the keys. If you are a landlord or property manager, we can work with the person who has access to the unit.
Can I choose my own lock and have you install it?
Often yes. We will check that it suits your door's thickness and prep, and tell you honestly if we think a different grade or type would serve you better. If a lock turns out to be a poor fit for the door, we will explain why before starting.
