What does lock installation actually involve?
Lock installation sounds simple until you see how many ways it can go wrong. A new lock is only as good as the door it sits in. If the bore hole is a hair off, if the strike plate is screwed into thin trim instead of the frame, or if the latch does not line up with the keeper, you end up with a lock that sticks, spins loose, or can be defeated with a firm shoulder. Good installation is mostly about the door, the frame and the fit, and only partly about the hardware you buy.
At Wilshire Lock & Key we have been fitting locks since 1987, and the work covers a wide range: a first deadbolt on a bare door, a lever handle set to replace a worn knob, a mortise lock in an older frame, a security lock on a rear unit, or a full set of commercial hardware on a shop entrance. This page is about putting new hardware onto a door correctly. If your lock is already there and just needs different keys, that is a separate job, and we explain the difference further down.
People in Cudahy usually call us for installation in a few situations: a landlord is adding hardware to a unit that never had decent locks, a tenant or owner has a door with a damaged or missing lockset, a new storefront tenant needs a working entrance, or someone simply wants a stronger lock on the front door than the builder-grade one that came with the place.
Which lock should go on which door?
There is no single right lock. The right choice depends on the door material, the thickness, what the door protects, and who needs to use it every day. Here is how we think about the common types, using the terms you will see on a hardware label.
We will tell you plainly when a cheaper-looking option is enough and when it is not. If a door is hollow, thin or badly damaged, no lock will make it secure, and we say so before we start drilling.
- Deadbolts: the standard answer for exterior doors. A properly set deadbolt with a solid strike plate and long screws into the frame does most of the real security work. For this specific job see our page on deadbolt installation in Cudahy.
- Lever lock installation: lever handles are easier on hands than round knobs, which matters for older residents, children and anyone carrying groceries. They also suit accessibility needs in commercial spaces. A lever set can be a simple passage latch, a privacy set or a keyed entry set.
- Mortise lock installation: a mortise lock sits inside a deep pocket cut into the edge of the door, and it combines the latch and the deadbolt in one body. You find them on older doors and on many commercial entrances. Fitting one correctly means cutting the pocket accurately, so this is not a casual job.
- Security lock installation: this covers hardware chosen for resistance to picking, drilling and forced entry, such as reinforced strike plates, longer bolts and restricted keyways. It makes the most sense on rear doors, unit entrances and anywhere a break-in would be costly.
- Keyed entry sets and combination sets: a deadbolt paired with a handle set is the usual front door lock installation for houses and rental units. Which pairing works depends on the existing bore holes in the door.

Call (213) 577-1366How do we handle a lock installation step by step?
Every installation follows the same discipline, whether it is one door or a row of them. We do not rush the measuring, because that is where bad installs begin.
- You call (213) 577-1366 and tell us the door type, whether a lock is already on it, and what you want the lock to do. We will ask a few questions about the door and the frame so the right hardware comes on the van.
- We look at the door in person: material, thickness, condition of the edge and the frame, and whether existing holes can be reused. If the door or frame is the weak point, we tell you before any work starts.
- We agree on the hardware and the scope of the job with you, and explain what will affect the cost, so there are no surprises when the work is done.
- We mark and cut the bore and edge holes with proper templates, set the latch and bolt, and fit the strike plate into solid framing with screws long enough to reach the stud, not just the trim.
- We install the lock body, trim and cylinders, and then test it repeatedly with the door open and closed, from inside and outside, to confirm the bolt throws fully and the latch catches cleanly.
- We hand over the keys, explain how the hardware works, and clear away debris. If the job is for a landlord with several doors, we label and organize the keys so they are usable later.
What affects the cost of lock installation in Cudahy?
We do not quote prices on a web page, because a fair figure depends on the door in front of us. What we can do is explain exactly what moves the cost up or down, so you can judge any quote you get, ours or anyone else's.
The biggest factor is the hardware itself. A basic keyed entry set and a high-security deadbolt with a restricted keyway are different products at very different cost levels. A mortise lock body costs more than a bored cylindrical lock, and fitting it takes longer.
The second factor is the door. Installing onto a door that is already drilled for a standard bore is quick. A door that has never had a lock, a door with old holes in the wrong places, or a door that needs patching or a reinforcement plate takes more labor and sometimes extra parts.
Quantity matters too. Fitting one door is a single trip with a set amount of setup. A landlord doing several units on the same property can often be handled efficiently in one visit, which is usually the more economical route compared with returning door by door.
Finally, timing and location play a part. After-hours and emergency calls cost differently than scheduled daytime work, and the distance from our Westwood storefront matters for mobile service. Cudahy is about 16 miles from our base, and we factor that in honestly. We will give you the details of the job before we start, not after.
- Type and grade of lock or lock set
- Door material, thickness and condition
- Whether the door is pre-drilled or needs new holes
- Frame repair or reinforcement needs
- Number of doors on the same visit
- Scheduled daytime visit versus an urgent after-hours call

Call (213) 577-1366What does lock installation look like on a Cudahy lot?
Cudahy has a housing pattern you do not see in many places. The city is known for its deep, narrow parcels left over from the original one-acre ranchito subdivision. A typical lot holds a front house with several rental units behind it, which makes Cudahy one of the densest cities in the country. Most of the structures are renter-occupied and date from the 1920s through the 1960s, and long shared driveways with gates are common.
That layout shapes the installation work we expect to do. A rear unit set deep on a lot has a front door that nobody walking down the street can see. Lockouts at rear rental units are a real local scenario, and the lesson from them is practical: a unit entrance with a worn or missing lock is a problem for the tenant and the owner both. Fitting a solid deadbolt and a sturdy handle set on that door, with a strike plate properly anchored, is one of the more useful jobs we do for these properties. If you are locked out of one right now, our apartment lockout service is the page to read first.
Because the same address often shelters a front house and several units, hardware decisions touch many people. Mailbox lock replacement for multi-unit properties sharing one address is a common need, and if the cluster boxes also need new locks, we can handle that through our mailbox lock replacement work. Long shared driveways with gates also call for padlock and gate hardware service, which we cover separately under gate lock repair.
Here is how this plays out across the city, using the areas we work in:
- Clara Street corridor: older residential parcels where a front house and rental units behind it often need matching hardware on several doors, so installation can be planned as one visit with organized keys.
- Santa Ana Street area: homes and small rental clusters from the mid-century era, where original door hardware is often worn and new lever lock installation or a fresh deadbolt is a straightforward upgrade.
- Lugo Park area (Otis Ave): residential doors near the park where a front door lock installation is often prompted by a move-in, a tenant change or a damaged lockset.
- Atlantic Avenue corridor: the commercial strip, where shop entrances need commercial lock installation, covered in the next section.
- LA River edge (southeast, near the river bike path): residences and gated areas where rear doors and side gates benefit from stronger security lock installation.
- 90201: the single ZIP code that covers the whole city, so wherever you are in Cudahy, you are inside our regular service area.

Call (213) 577-1366Can you do commercial lock installation along Atlantic Avenue?
Yes. Commercial lock installation follows a different logic than residential work. Shop doors are used all day, so the hardware has to survive heavy traffic, and the lock often has to meet fire and egress requirements. A storefront entrance might need a heavy-duty mortise lock, a keyed lever, a deadbolt for after-hours security, or a combination of those, depending on the door and the business.
Storefront lock repair along the Atlantic Avenue commercial strip is a real local scenario. When a lock fails there, the owner often asks whether to repair or to install fresh hardware. If the existing lock is salvageable, storefront lock repair is usually the lighter-cost option. If the hardware is worn out, mismatched or poorly fitted, a new installation is the better answer, and we can look at the complete set of commercial door hardware in the same visit.
We will check the door itself first. A commercial door that drags, sags or fails to close squarely will wear out any new lock, so we address alignment before fitting a new body. When the work is done, you leave with a door that closes, latches and locks the way it should, and keys that are tracked clearly so you know who holds what.
When is installation the wrong answer?
Not every lock problem needs a new lock. Part of being straight with customers is saying so when we can. If your locks are in good shape but you are worried about who has keys, a lock rekey changes the internal pins so old keys stop working, and you keep the hardware you already own. That is often the more economical route, especially for a landlord turning over a unit.
If a lock is already installed but is damaged, worn out or outdated, lock replacement may be the better label for the job, even though the work overlaps with installation. The difference is mostly about what is on the door when we arrive. If the door is bare, you need installation. If there is a failing lock, you are weighing repair, rekey or replacement.
We also look at the door's weather and wear. Cudahy sits on flat ground beside the LA River channel, in a mild inland-plain climate. Salt-air corrosion is not a concern here, so you do not need to pay for coastal-grade finishes. Summer heat does cause minor movement in older wood doors, which can shift a bolt slightly out of alignment, so we check the fit when we set the strike and leave a little clearance to keep the lock working smoothly.

Call (213) 577-1366Why call Wilshire Lock & Key for lock installation?
We try to keep this part short and honest. We have been in business since 1987, with a storefront at 10740 Wilshire Blvd in Westwood and mobile service vans that reach 140 cities across Los Angeles and Ventura counties, Cudahy among them. Our phone line is answered 24 hours a day, 7 days a week, year-round, at (213) 577-1366.
When you call, you are talking to one company, not a call center that passes your job to whichever contractor picks it up. David, the owner and lead technician, oversees the work. That matters on installation more than almost anything, because the quality of a fit shows up months later, not on the day.
If you need more than installation, our residential locksmith page and our mobile locksmith page explain the broader service. Property owners with several units can read about our work for landlords. You can also use our contact page if you would rather write us than call.
How should you vet any locksmith before work begins?
California requires locksmith companies to hold a license from the Bureau of Security and Investigative Services (BSIS), called a Locksmith Company (LCO) license. Whoever you hire, ask to see their license number before they start drilling or cutting, and check it. A legitimate company will give it to you without argument.
Also ask for a clear description of the work and the factors that determine the cost before work begins. Be cautious of anyone who quotes a rock-bottom figure on the phone and then changes it at the door, or who insists on drilling a lock that could have been picked or adjusted. A trustworthy installer explains what they are going to do and why.
Frequently asked questions
What is the difference between lock installation and lock replacement?
Installation means fitting a lock where there is none, or fitting a new type of lock that needs new holes or a new door preparation. Replacement means swapping out an existing lock that is worn, broken or outdated. The skills overlap, and we will tell you which you need after seeing the door.
Can you install a lock on a door that has never had one?
Yes. We measure the door, check its thickness and material, cut the bore and edge holes, set the latch and bolt and fit the strike plate into the frame. If the door is too thin or damaged to hold a lock safely, we tell you before starting and explain the options.
Do you install locks on rear rental units in Cudahy?
Yes. Many Cudahy lots have a front house with rental units behind it, and the rear unit doors often need new deadbolts, handle sets or security hardware. We can fit several doors in one visit and organize the keys so they are easy to manage.
Do you handle commercial lock installation for storefronts?
Yes. We install commercial hardware such as mortise locks, keyed levers and deadbolts on shop entrances, including along Atlantic Avenue. We check the door's alignment first, because a door that drags will wear out new hardware quickly.
How much does lock installation cost in Cudahy?
It depends on the lock itself, the condition of the door, whether new holes are needed, how many doors are being done and when you need the work. We do not publish numbers here because they would not be honest without seeing the door. Call (213) 577-1366 and we will explain what drives the cost for your job.
Is a mortise lock better than a standard deadbolt?
Neither is better across the board. A mortise lock is a heavy, durable body set into the door edge and is common on older doors and commercial entrances. A deadbolt with a solid strike is a strong and simple choice for most residential doors. The door and your use determine which fits.
Are you licensed to do this work?
We do not state a license number on this page yet. California requires locksmith companies to hold a BSIS LCO license, and you should ask any locksmith, including us, to show it before work starts.
Can I call at night to arrange an installation?
Our phone is answered 24 hours a day, 7 days a week, year-round, at (213) 577-1366. Planned installations are usually easier to schedule in daytime, but if a door will not secure and you need help after hours, call and we will discuss what is possible.
