What lock replacement means, and when it makes sense
Lock replacement means we take the old hardware off your door and fit new hardware in its place. That might be a single knob or lever, a deadbolt, or the whole set. It is different from rekeying, where the lock body stays and only the internal pins change, and different from repair, where we fix the one part that is failing. Most lock replacement calls in Lomita start the same way: a key that turns only some of the time, a deadbolt that no longer throws all the way, a handle that spins loose, or a lock that has clearly been forced.
Replacement is the right call when the hardware itself is the problem. A lock that has been pried, drilled, or kicked is compromised even if it still turns. A lock worn out after decades of daily use will keep failing and tends to pick the worst moment to do it. And a lock can simply be outdated, like a builder-grade knob set left by a previous owner, a lock nobody can find keys for, or a mismatched set where every door on the property uses a different key. If you need to replace a broken lock or want a security lock upgrade, this is the page for it.
Should I replace the lock, repair it, or just rekey it?
Not every sticky lock needs replacing, and we would rather tell you that than sell you hardware you do not need. When we look at your door, we sort the problem into one of three buckets.
If the lock is sound but something small has gone wrong, we say so, and if you do end up needing a different fix, our other pages cover it in detail.
- Repair: if one part is worn, a latch is misaligned, a set screw has backed out, or a cylinder just needs attention, lock repair is usually the lighter-cost option and keeps hardware you already like.
- Rekey: if the lock is in good shape but you have lost a key, moved into a new place, or want old keys to stop working, rekeying is usually the more economical route.
- Replace: if the lock is broken, forced, loose inside, missing parts, no longer matches the rest of the door, or is too weak for what you are protecting, replacement is the honest answer.
How does a lock replacement visit work?
Here is the sequence on a typical house or apartment door. Business doors follow the same logic with different hardware.
- You call (213) 577-1366. Tell us which door it is, what the lock is doing, and whether the door can currently be secured. Someone answers at any hour, any day.
- We look at the whole door, not just the lock. That means the thickness, the bore holes, the edge, the strike plate, and the frame, and whether the door itself has shifted or swelled.
- We lay out the options in plain language: replace or repair, what grade of hardware makes sense, which finishes are available, and how many locks should share one key.
- We give you the cost of the job before we start work, so the number is settled before any hardware comes off the door.
- We remove the old hardware and check for damage around it, especially after a break-in attempt, when splintered wood or a bent strike plate can undermine a perfectly good new lock.
- We fit the new lock and align the latch and strike so the bolt throws fully without you needing to lift, push, or slam the door.
- We test it with you: every key, the thumb turn, the bolt, and the door closing from the outside. Then we hand over the keys and any packaging you want to keep.

Call (213) 577-1366What affects the cost of lock replacement in Lomita?
We do not publish numbers on a web page because the same phrase, replace a lock, covers very different jobs. What we can do is tell you exactly what moves the cost up or down, so you can judge any quote you get from us or anyone else.
- The hardware itself: a basic knob set, a heavy-duty deadbolt, a high-security cylinder, and a smart lock sit in very different places. Grade and build quality are the biggest factor.
- How many locks: replacing one front door lock is a different job from refitting every exterior door, a garage side door, and a workshop.
- Keying: having several new locks all work with one key takes extra setup, and it is usually worth it.
- Door condition: a door that is swollen, out of square, or damaged from a forced entry may need prep work before new hardware will sit properly.
- Unusual sizes: older doors and some mobile home doors do not use standard bore sizes or backsets, and fitting them can take more care or special parts.
- Time of day: after-hours and emergency calls cost differently than a scheduled daytime appointment, and you can often choose between the two if the door is still secure.
- Travel: Lomita is about 24 miles from our Westwood base, and we factor that in honestly rather than hiding it.
Front door, house, and apartment lock replacement
A front door lock replacement is the most common request we get, and the front door is also where the most can go wrong with an older home. Lomita has plenty of 1940s and 1950s cottages and ranch homes, and many of them still have original or very old wood doors. In the damp months, when the marine layer sits over the area, those doors swell. A swollen door can bind the latch against the strike so badly that it looks like the lock has failed. Before we sell you a new lock, we check whether the door is the real culprit. Sometimes the fix is adjusting the strike or easing the door, and the old lock goes back on working fine.
When the lock really is worn or broken, we replace it with hardware sized to your door. If the door has no deadbolt at all, or only a knob lock with a thin latch, a separate deadbolt installation adds real resistance to forced entry. If you want keypad or app-based entry, smart lock installation is its own job, and we will tell you plainly where a smart lock makes sense and where a good mechanical deadbolt is the better choice.
Apartment lock replacement works the same way, with one practical note: if you rent, check with your landlord or property manager before changing hardware, since they may need keys or have their own requirements. If you are the owner or manager of a small building, we can work through all the doors in a single visit and key them in a way that is easy to manage.

Call (213) 577-1366Business lock replacement and security upgrades
Commercial lock replacement is a different animal from residential work. Storefront doors are often aluminum-framed glass with narrow-stile hardware, rim cylinders, or mortise locks, and they get used hundreds of times a day. Hardware wears out faster, and a failed lock on a business door is a security problem and a lost-business problem at the same time.
When a storefront lock is worn but the door hardware around it is sound, storefront lock repair may be all you need. When the lock, handle, or latch is beyond saving, or you want a business security upgrade because a former employee still has a key or the door was tampered with, we replace it and re-key the new hardware so you control who holds access. If the whole door setup is tired, including closers, push bars, and handles, commercial door hardware covers what that larger job looks like.
A good business security upgrade is rarely just a pricier lock. It is usually a combination of the right grade of cylinder, solid strike and frame, and a key plan that matches how many people actually need to get in. We talk through that with you before recommending anything.
Lock replacement around Lomita: what we see on the ground
Lomita is a compact city, ZIP code 90717, and the lock jobs follow its streets. Along the Narbonne Avenue corridor and near Pacific Coast Highway, you find small apartment buildings where several doors share the same age and the same worn hardware, and where replacing the locks building-wide often makes more sense than handling one door at a time. Along the Pacific Coast Highway corridor you also find storefronts and several mobile home parks. Mobile home lock replacement is a regular job for us there: the doors are lighter than a standard house door, the hardware sizes often differ, and we confirm what fits on site before removing anything.
Along the Lomita Boulevard corridor and the residential streets around it, the older cottages and ranch homes are on deep lots, so a lot of properties have a detached garage or workshop with its own lock that nobody has thought about in years. Those outbuildings deserve the same attention as the front door, and replacing a rusty padlock hasp or worn side-door lock is often a quick upgrade. Newer townhome and condo infill has its own wrinkle: if you are in an HOA, check whether the association has rules about exterior hardware finish before you pick a style.
The climate here is gentler than at the beach itself. Lomita sits at the foot of the Palos Verdes Peninsula a couple of miles from the water, so you get marine layer dampness but only mild salt-air exposure. That means locks here more often fail from age, heavy use, and swollen doors than from heavy corrosion. We also work in the neighboring areas near Harbor Hills, near Walteria in Torrance, and near Harbor City, and our mobile locksmith vans cover all of it.

Is your locksmith licensed? What to ask before work starts
California requires locksmith companies to hold a Locksmith Company license (LCO) issued through the Bureau of Security and Investigative Services, known as BSIS. Whoever you hire for lock replacement, ask for their LCO license number before they touch your door, and check that it matches the company name on their van or invoice. A locksmith who dodges the question is telling you something.
A reputable company will also be comfortable explaining the work and the cost before starting. If you ever feel pressured to approve a job on the spot, or the price changes once the lock is off the door, stop and ask questions. Lock replacement should feel like a clear decision, not a corner you were backed into.
Frequently asked questions
How do I know if my lock needs replacing or just repair?
If the lock still turns smoothly but a latch is misaligned or a screw is loose, repair is usually enough. If the lock has been forced, feels loose inside, grinds, sticks regardless of the door, or is missing parts, replacement is the better call. We check the door too, since swollen wood can imitate a failed lock.
Can you replace a broken lock after a break-in attempt?
Yes. Call us any hour at (213) 577-1366. We look at the lock, strike plate, and door frame, because forced entry often damages more than the lock. We replace what is compromised so the new hardware sits on solid wood and holds up, and we tell you if the door itself needs more attention.
Do you replace locks on mobile homes in Lomita?
Yes. Mobile home doors are often lighter than standard house doors and may use different bore sizes or backsets, so we confirm what fits on site before removing anything. There are several mobile home parks along and near Pacific Coast Highway, and we regularly work with that type of door.
Will the new lock work with my existing keys?
Sometimes, but usually not. New hardware comes with its own keying. If you want a new lock to match your other locks, we can key it alike so one key opens several doors. If you want a clean break from old keys, the new lock simply comes with fresh ones.
Can you replace locks for a small business or storefront?
Yes. We handle commercial lock replacement and business security upgrades, including storefront doors, rim and mortise hardware, and re-keying new locks so you control who has access. We will also tell you if repair is a lighter-cost option than replacing the whole setup.
What does it cost to replace a lock?
It depends on the grade of hardware, how many locks, the keying, the condition of the door, unusual sizes, time of day, and travel. We do not quote numbers over a web page. We look at the door, explain the options, and give you the cost before any work begins.
Do I need to be home when you replace the lock?
Someone with authority over the property should be there, or you should arrange access clearly with us beforehand. We test the lock with you at the end and hand over the keys, so it works best when you are present. For rentals, coordinate with your landlord first.
Can I upgrade to a better lock while you are there?
Absolutely. A security lock upgrade is a common reason people call. We can step up the grade of hardware, add a deadbolt, or discuss high-security cylinders or a smart lock. We will be honest about what actually improves protection on your door versus what is just a nicer finish.
Do you serve Lomita at night and on weekends?
Yes. We answer 24 hours a day, seven days a week, year-round at (213) 577-1366. If a door will not lock at 2 a.m. or on a holiday, call and we will work out the right next step with you. If the door is secure, you can also schedule for daytime.
