What does lock installation involve on a Carson door?
Lock installation means fitting a lock where there isn't one, or fitting a different type of lock than the one that used to be there, and making sure it works with the door it's going into. On a fresh, well-prepared door that can be straightforward. Most doors aren't fresh. They have old bore holes, painted-over strike plates, frames that have shifted a quarter inch, and edges that have been planed more than once.
When people search for door lock installation, they usually want one of a few things: a new knob or lever on an interior or office door, a front door lock installation after a move or a break-in attempt, a deadbolt added above an existing handle, or a commercial lock put on a shop, office, or warehouse door. We do all of these. The approach stays the same each time: look at the door and frame first, choose hardware that suits what we see, and test the finished work before we hand over the keys.
This page is about installation only. If your lock works and you just want different keys, that's a rekey. If a lock is worn out or damaged, that's usually a replacement. We lay out the difference below so you don't pay for the wrong job.
Is new lock installation what you actually need?
A fair number of calls that begin as 'I need a new lock' end up as something else once we look at the door. Being straight about that matters, because the right job is often the lighter one.
On the phone we ask what's on the door now, what you want it to do, and whether anyone has had it apart before. Photos help. If the picture changes once we're at the door, we tell you before any work starts.
- If you only need old keys to stop working, after a move, a roommate leaving, or a lost key, a lock rekey changes the inside of the lock you already own and is usually the more economical route.
- If a lock is worn, sticking, damaged, or you just want a different style in the same hole, lock replacement swaps one for the other.
- If a door has no lock, has a lock in the wrong place, needs a hole bored or enlarged, or you want a second lock added, that is installation.
- If you're moving from one lock type to another, say a knob to a lever or a bored lock to a mortise lock, that's installation too, because the door itself may need work.

Call (213) 577-1366How do we install a new lock, step by step?
Every installation is a little different, but the sequence below is how we work on nearly every door. None of it is exotic. The difference between a lock that lasts and one that causes trouble is usually whether these steps were skipped.
- Look at the door. We check thickness, material (solid wood, hollow core, metal, fiberglass, or aluminum storefront), condition, and whether it swells or drags at certain times of year.
- Check the frame and the strike side. A lock is only as strong as what it bolts into, so we look at the jamb, the strike plate, and how far the frame has moved.
- Agree on the hardware with you: the function (entry, privacy, passage, or keyed), the finish, the grade, and whether it should match other locks or work with a single key.
- Prepare the door. If a hole already exists, we confirm it suits the new lock. If not, we mark, bore, and chisel to the template, keeping the edges clean so the door isn't weakened or splintered.
- Fit the lock body, latch, and strike, and align them so the bolt moves freely into the strike without anyone lifting or pushing the door.
- Reinforce where it matters, usually with longer screws that reach the framing behind the strike and a reinforced strike plate where it makes sense.
- Test the work. We cycle the lock repeatedly with the door open and closed, try every key from both sides where that applies, and check how the door sits in the frame.
- Walk you through it. We hand over the keys, explain any settings, and point out anything about the door you should know about, like a frame that's started to move.
Which types of locks do we install?
Different doors and different households call for different hardware. Here is how the main categories break down, using the terms people most often search for.
- Front door lock installation: usually a handle set or knob paired with a deadbolt. Placement, backset, and the strike matter as much as the lock itself, since the front door is the one that gets tested.
- Deadbolts on their own: adding a separate deadbolt has its own details, from hole size to door thickness. We cover that in deadbolt installation.
- Lever lock installation: levers work without gripping and twisting, so they suit interior doors, offices, and households where hands aren't as strong as they used to be. They're also common on commercial doors.
- Mortise lock installation: a mortise lock sits in a deep pocket cut into the edge of the door instead of a simple round bore. You'll find them on older commercial and storefront doors and some older entry doors. The cutting is precise and slower, and the door has to be suitable. Sometimes a modern bored lock with proper door prep is the lighter-cost option, and we'll say so if that applies to your door.
- Security lock installation: higher-grade deadbolts, reinforced strikes, and cylinders that resist picking and drilling. If you want restricted keys nobody can copy at a hardware counter, see high-security locks.
- Smart locks: keypad and app-controlled locks involve batteries, setup, and tight door alignment, so they have their own page on smart lock installation.
- Commercial lock installation: storefront, office, and warehouse doors take heavier hardware and have egress considerations. More on that in commercial door hardware.

Call (213) 577-1366What affects the cost of lock installation in Carson?
We don't quote numbers on a web page, because the same phrase, 'install a lock,' covers a ten-minute swap on a prepared door and a half-day job on a worn steel frame. What we can do is tell you honestly what moves the cost up or down.
Before we start, we explain the scope of the job and what is driving the cost. If we open up the door and find something that changes the work, we tell you before continuing, not after.
- Lock type and grade: a basic interior lever and a high-grade security deadbolt are very different products.
- Door material and condition: solid wood, hollow core, metal, and aluminum storefront each need different handling, and a damaged edge or a split near the latch takes extra time to repair.
- New holes versus existing holes: if the door is already bored for the lock, it's quicker. Cutting a new bore or a mortise pocket is more involved.
- Number of locks: several doors keyed alike takes planning but often goes faster per door than separate visits.
- Keying requirements: matching an existing key, keyed-alike sets, or restricted keyways all add steps.
- Hardware you supply versus hardware we supply: we're happy to install what you've bought if it suits the door, and we'll tell you if it doesn't.
- Timing: work arranged in regular hours is simpler than a middle-of-the-night call, which is fair to say plainly.
What should Carson homes and properties know about lock installation?
Carson is mostly 1950s to 1970s single-family tracts, and neighborhoods like the Carousel Tract and Dominguez are good examples of what that means at the door: decades of paint on the strike plate, old bore holes from previous locks, and frames that have settled. When we install a new lock on a door like that, a lot of the work is cleaning up what's already there so the new hardware sits correctly.
Carson sits on the flat inland harbor plain. The marine layer brings overcast mornings but, according to the area's climate profile, little salt-air corrosion, so finish choice is mostly about looks and wear rather than fighting coastal rust. What does matter is the weather swing. Summer heat and damp winter mornings make wood doors expand and contract, and a latch that works fine in the afternoon can bind first thing in the morning. We check the fit with that movement in mind and leave sensible clearance rather than setting everything tight on a warm day.
Townhome communities like Scottsdale have their own pattern. Entry doors and mailboxes are often part of a shared look, so it's worth checking with your HOA before choosing a finish. Those communities also generate steady mailbox lock work, which is a separate job covered under mailbox lock replacement.
Mobile home lock replacement is a regular part of the work across the city's many parks. Mobile home doors are often lighter and thinner than a standard house door, so we look at the door before promising any particular lock will fit, and we bring options in the van. The right screws and the right backset matter more on a lighter door.
Near CSU Dominguez Hills, the University area has newer infill and student-oriented rentals where doors see constant turnover and keys get lost. Landlords and tenants there often ask for a new lock fitted, or an extra one added, to tighten up a door that's been used hard.
We work across 90745, 90746, and 90747, from the Avalon Boulevard and Carson Street corridors to the Sepulveda Boulevard corridor and South Carson near the Wilmington border. Our storefront is on Wilshire Blvd in Westwood, about 24 miles from Carson, and our vans come to you.

Call (213) 577-1366What about commercial lock installation near Carson's industrial areas?
Industrial and logistics buildings sit right up against residential streets in Carson, and the work follows. Warehouse and distribution-facility lock service along the 405 industrial corridors is a different job from a house door: heavier steel doors, high daily traffic, and sometimes several doors that need to work on the same key system.
Storefronts at SouthBay Pavilion and along the Avalon Blvd corridor bring their own details. Aluminum storefront doors have narrow stiles, so the lock has to fit a small space, and the hardware needs to hold up to being opened and closed all day.
Commercial lock installation also means paying attention to how people get out. A door that has to let people leave quickly in an emergency can't simply be fitted with a lock that needs a key from the inside, so we ask how the door is used before choosing hardware. If you're setting up several doors, ask us about keying them so staff carry fewer keys. The right setup depends on the building, and we'd rather talk it through than guess.
Why call Wilshire Lock & Key for lock installation?
We've been in business since 1987, and a lot of that time has been spent fixing the shortcuts other people took on installations. Here is what you get when you call us:
- A real storefront at 10740 Wilshire Blvd, Los Angeles, CA 90024, plus mobile service vans, so there's a place and a company behind the van.
- One company doing the work. There are no dispatch middlemen passing your job to whoever's free, so the person you talk to is part of the company that does the work.
- David, the owner and lead technician, oversees the work and the standards we hold it to.
- The phone is answered 24 hours a day, 7 days a week, year-round, at (213) 577-1366. If a lock has failed and you can't secure your door tonight, ask about our emergency locksmith service.
How can you check a locksmith before they start?
California requires locksmith companies to hold a BSIS LCO license, issued through the Bureau of Security and Investigative Services. Ask any locksmith for their license number before work begins, and that includes us. It's a reasonable question and one you should feel free to ask every time.
When you're ready, call (213) 577-1366 and tell us the door, the lock you have now, and the lock you want. We'll tell you plainly whether it's installation, a rekey, or a replacement.
Frequently asked questions
How long does a lock installation take?
It depends on the door. A standard lock on a door that's already bored is quick. A new bore, a mortise pocket, or a repair to a damaged edge takes longer. We look at the door first and tell you what to expect before we begin.
Can you install a lock I bought myself?
Often, yes. We check that the lock suits the door's thickness, material, and use. If the hardware is a poor fit or too light for the job, we tell you before cutting anything, and you can decide whether to use it or switch.
Do you install locks on mobile home doors in Carson?
Yes. Mobile home lock replacement is a regular part of the work across Carson's parks. Those doors are often lighter than standard house doors, so we check the door and choose hardware that fits it rather than assuming a standard lock will work.
What's the difference between a lever and a knob lock?
A lever works with a push-down motion and doesn't need gripping or twisting, which makes it easier for many people to use. A knob is the more traditional round style. Both can be installed with keyed, privacy, or passage functions, so the choice is mostly about ease of use and appearance.
Do I need a mortise lock?
Only if your door already has a mortise pocket or you specifically want that style. Mortise locks are common on older commercial and storefront doors. If your door isn't set up for one, a modern bored lock with proper prep is often the lighter-cost option, and we'll tell you honestly which fits better.
Can you do commercial lock installation for a warehouse or shop?
Yes. We install locks on storefront, office, and warehouse doors in and around Carson. We ask how the door is used and how people exit, then choose hardware to match. Multiple doors can be keyed so staff carry fewer keys.
Will a new lock work with my existing keys?
Sometimes. It depends on the brands and whether the new lock can be keyed to match your current key. If you want one key for several doors, tell us up front so we can plan the keying before we start.
Do you install locks at night or on weekends?
Our phone is answered 24 hours a day, every day of the year at (213) 577-1366. Call whenever you need us and we'll arrange the work. For an urgent situation where a door can't be secured, tell us that first.
How do I know a locksmith is properly licensed in California?
California requires locksmith companies to hold a BSIS LCO license. Ask any locksmith for their license number before work begins and check it with the state. A company that won't give you the number is worth walking away from.
