When is it time to replace a lock instead of nursing it along?
A lock rarely announces that it is finished. It starts by sticking in the afternoon, then the key needs a little jiggle, and then one morning the cylinder spins without catching the bolt, or the key snaps off in your hand. By then you are standing at your own door with a problem that could have been handled on your schedule instead of the lock's.
Replacement is the right call when the hardware itself is the problem, not just who holds the keys. Worn internal parts, a bent latch, a cracked housing, a finish worn clean through, a deadbolt that no longer throws all the way, or a lock that was forced during an attempted break-in all point to new hardware. So does a lock so old that matching parts and key blanks are hard to find. Whether it is a front door lock, a back door, or a business entrance, the test is the same: can this lock be trusted to hold tomorrow?
- The key turns hard, sticks, or only works with the door held a certain way
- The bolt does not fully extend or retract, or the latch drags on the strike plate
- The cylinder wobbles, spins freely, or has visible damage from a pry or drill attempt
- Parts of the lock are loose, cracked, or rusted through
- The hardware is decades old and no one knows how many keys are out there
- You want a security lock upgrade, such as a better-grade deadbolt or a keypad lock
Should you replace, rekey, or repair the lock?
We do not start from the assumption that you need new hardware. Sometimes the honest answer is that the lock is fine and the keys are the issue. If the lock is solid but you lost a key, moved into a new place, or ended a roommate arrangement, rekeying the existing lock is usually the more economical route, because the cylinder is reset to a new key and the hardware stays on the door.
If the lock is sound but a single part has failed, such as a spring, a latch, or a strike, a lock repair may be all that is needed. Replacement earns its place when the lock is worn out, damaged, mismatched to the door, or no longer something you want protecting your home or business. When you call, describe what the lock is doing and we will tell you which of the three fits. If you are unsure, we look at it in person before anything is removed.

Call (213) 577-1366How does a lock replacement work, step by step?
Every door is a little different, but the process we follow stays consistent whether it is a bungalow front door or a rear shop entrance.
- You call (213) 577-1366 and describe the door, the lock, and what went wrong. We answer around the clock, so this works at 2 a.m. as well as midday.
- We tell you what we expect to be involved and what drives the cost, and we send a mobile van from our fleet. We are one company, with no third-party dispatcher passing your job along.
- On arrival we inspect the lock, the door, the latch and strike, and the frame. A new lock is only as good as what it is mounted into, so we check for splitting wood, sagging hinges, and misaligned strikes.
- We confirm the plan with you before work starts: which lock, which grade, and whether anything else on the door should be addressed.
- We remove the old hardware, fit the new lock, and adjust the latch and strike so the bolt moves freely without forcing.
- We test the lock repeatedly with the door open and closed, hand you the new keys or codes, and explain how to operate it.
- We take the old hardware with us unless you want to keep it.
What kinds of locks do we replace?
Most calls fall into a few categories. Residential lock replacement covers front door locksets, knob and lever sets, and deadbolts on houses, bungalows, and cottages. Apartment lock replacement covers unit entry doors, and sometimes patio or secondary doors. Business lock replacement covers storefront doors, back doors, office suites, and any entry that sees heavy daily use.
If what you really want is an additional layer of protection, a new deadbolt is often the single most useful addition to a door that has only a spring latch. If you are tired of carrying and losing keys, we can talk through a smart lock, including the honest tradeoffs around batteries, power, and how it behaves when something fails. For people who want stronger cylinders and key control, our page on high-security locks explains what the extra grade actually buys.
- Front door and entry locksets, including handle sets and lever sets
- Deadbolts, single and double cylinder
- Keypad and smart locks
- Rear door, patio door, and side gate entry hardware
- Security screen door locks
- Apartment entry and unit door locks
- Storefront, office, and back-of-house business locks
How much does lock replacement cost in San Fernando?
We will not quote a number on a web page, because the honest answer depends on the door in front of us. What we can do is tell you exactly what moves the price, so nothing surprises you.
Hardware grade is the biggest factor. A basic builder-grade lockset and a heavy-duty deadbolt with a hardened strike and reinforced plate are very different products. Quantity matters too: one lock is a short visit, while a whole house or a row of storefront doors takes more time and materials. If you want every new lock keyed to one key, that adds some work but saves you a ring of keys.
Door condition counts. A lock fitted to a swollen, split, or badly drilled door may need the door prepared or repaired first. Specialty hardware, such as commercial-grade or smart locks, costs more than a plain cylinder. Timing and travel also play a part: an after-hours call differs from a scheduled visit, and we are 23 miles from our Westwood storefront, so travel is part of the picture. Finally, if rekeying or a small repair solves the problem, you will pay for that instead of new hardware. We tell you before we start, and you decide.

Call (213) 577-1366Lock replacement for San Fernando houses, bungalows, and apartments
San Fernando is a compact, independent city of about 2.4 square miles, and its housing reflects it: early-1900s bungalows, Spanish-style cottages, and postwar homes on small lots, with small apartment buildings clustered closer to the downtown mall. Many of those older homes still carry their original door hardware. That is charming until the latch wears out, the key blank is no longer made, and nobody knows who held a copy in 1990. For homes in the 91340 ZIP code, replacing a lock that old is often a better move than patching it.
Around Las Palmas Park, older bungalows often call for a different approach: the door itself is old-growth wood that has been painted many times, and the lock bore may be a size or style that modern hardware does not match. We check the door, then fit hardware that suits it rather than forcing a mismatch. In the Civic Center and Pioneer Park areas, we see more apartment doors and rental units, where a fresh lock between tenants is simply sensible housekeeping.
Security screen doors are a common retrofit on pre-war homes here, and their locks take real abuse. Replacing a worn or broken security screen door lock is one of the most typical jobs in the city, and we bring hardware that fits those frames.
Climate plays a role too. Hot northeast-Valley summers expand wood doors and frames, which can make bolts bind and strikes misalign. Santa Ana wind events push fine dust into exterior cylinders, which wears keys and stiffens locks over time. Winters are mild with little corrosion risk, so rust is rarely the culprit here; heat, dust, and age usually are. When we replace a lock in San Fernando, we adjust for seasonal door movement and favor hardware that handles dust well.
Business lock replacement and security upgrades near the mall and Maclay
Storefronts line Maclay Avenue, Truman Street, and San Fernando Road, with plenty more around the San Fernando Mall downtown. Doors in these places are opened and slammed dozens of times a day, and the locks wear faster than anything on a house. A sticky storefront lock is not only an annoyance; it can leave a business unable to open on time or unable to close up securely.
For commercial lock replacement, we look at how the door is actually used. A shop with a single glass entry has different needs from an office with a back exit that must open from the inside under fire code, and some doors need panic hardware that a standard lockset cannot provide. If the issue is a damaged storefront entry rather than a full swap, our storefront lock repair page covers that side, and commercial door hardware covers closers, exit devices, and heavier-duty sets.
A business security upgrade is often the right time to rethink key control: who has keys, which doors need to be keyed alike, and whether a former employee still holds a working copy. Replacing locks is also the cleanest way to reset after a break-in attempt, a staff change, or a move into a space whose previous tenant is unknown. We handle that reset in one visit where we can.

Call (213) 577-1366Why call Wilshire Lock & Key for a lock replacement?
We have been in business since 1987, and we serve 140 cities across Los Angeles and Ventura counties, San Fernando included. That many years teaches you which hardware lasts, which fails in a year, and which brands are mostly marketing. We tell you that plainly.
We are one company with a storefront at 10740 Wilshire Blvd in Westwood and our own mobile service vans. When you call, you are not routed to a call center that sells your job to whoever is nearest; the work is done by our people. David, the owner and lead technician, oversees the work, so the standards come from someone who has been doing this for decades.
One more point worth knowing: California requires locksmith companies to hold a BSIS LCO license, and you should ask any locksmith you call for their license information before they start work. That is a reasonable thing to ask of anyone who will be handling the keys to your home or business.

What should you do before we arrive?
A little preparation makes the visit smoother. None of it is complicated, and if you cannot do any of it, we work around it.
- Note the brand and look of the current lock if you can, or send a photo so we know what we are replacing
- Locate any keys you still have, including spares, so we can test them before removal
- Decide whether you want new locks keyed alike, so one key opens every door
- If the door was forced, avoid pushing it shut hard; leave the damage as it is so we can assess the frame
- If you rent, confirm with your landlord first that you may change the lock
- Clear the area around the door so we can work without moving furniture
Frequently asked questions
How do I know whether I need a new lock or just a rekey?
If the lock works smoothly and feels solid, but you want to cancel old keys, rekeying is usually the more economical route. If the lock is worn, damaged, loose, or very old, replacement makes more sense. Describe what it is doing and we will tell you honestly which fits.
Can you replace the lock on a security screen door?
Yes. Security screen doors are common on older San Fernando homes, and their locks take a lot of wear. We fit hardware suited to those frames and check that it latches cleanly with the door's normal movement.
Will the new lock work with my existing keys?
It can. If you have several locks and want one key for all of them, we can key the new hardware to match, depending on the brands involved. If you want a clean break from old keys, we set the new lock to entirely new ones.
Do you replace locks at night or on weekends?
Yes. We answer the phone 24 hours a day, 7 days a week, year-round at (213) 577-1366. A lock damaged in a break-in attempt or one that will not secure the door does not wait for business hours, and neither do we.
Can you replace locks on my apartment or rental?
We can, but check your lease and speak to your landlord first, since many rentals have rules about who may change locks. Landlords and property managers often have us handle replacements between tenants, and we are glad to work with them.
Do you handle business lock replacement along Maclay Avenue and the mall?
Yes. We replace locks on storefronts, offices, and back entrances, and we can advise on panic hardware, closers, and keying across several doors. Commercial doors differ from home doors, so we look at how the door is used before choosing hardware.
Do you bring the new lock with you, or do I buy it first?
You can do either. We carry common hardware on our vans, and we can discuss options on the phone. If you have already bought a lock, tell us the model, and we will say whether it suits your door before we install it.
How can I tell a legitimate locksmith from a risky one?
Ask for their BSIS LCO license information, since California requires locksmith companies to hold one. Ask who will actually come to your door, and whether the company has a real address. Be cautious of anyone who refuses to explain what drives the cost before starting.
