When should you replace a lock instead of repairing it?
Lock replacement means taking out the hardware that is on your door now, whether that is a knob, a lever, a deadbolt or a mortise lock, and fitting new hardware in its place. It is the right call less often than people think, and we would rather say so than sell you something you do not need.
Replacement usually makes sense when the damage or wear is inside the lock itself, or when the lock was never good enough to begin with. Here are the situations where we most often recommend it:
- The lock has been forced, bent or pried, for example after a break-in attempt, and the cylinder or latch is no longer sound.
- A key snapped and the cylinder is scarred or the internal pins are damaged.
- The key has to be jiggled, lifted or forced, and the lock sticks more every month.
- The latch no longer retracts cleanly, the finish has worn through, or the screws will not hold in the door.
- The lock is an outdated or unbranded model and replacement parts are hard to find.
- You have no idea how many copies of the key exist, and the hardware is too worn or too basic to be worth rekeying.
What if the lock still works fine?
If the hardware is solid and your only worry is who has keys, a lock rekey changes the internal pinning so old keys stop working, and it is usually the more economical route. If the lock is sound but sticking or loose, a lock repair may be all it needs. We will look at the lock and tell you which of the three is honest advice for your door.
If you are locked out right now and have not yet gotten to the replacement question, our house lockout page covers getting you back inside first. We can then talk about replacing the lock once you are in.
How does lock replacement work, step by step?
The job is simple when it is done carefully, and most of the care is in the steps before and after the new lock goes in. Here is how we handle it from the first call.
- You call (213) 577-1366. The line is answered around the clock, every day of the year. Tell us which door it is, what kind of lock is on it and what is wrong. A phone photo of the lock and the edge of the door helps.
- We confirm the details that decide what fits: the door's thickness, the size of the bore hole, the backset, and whether you want a keyed deadbolt, a handle set, or both.
- A technician comes to you in one of our mobile vans, so the work happens at your door rather than at a shop.
- Before we change anything, we inspect the door and frame. A worn strike plate, a sagging hinge, a swollen edge or soft wood around the latch can make a brand-new lock fail, so we look for those first.
- We explain what we found and what the work involves, and you approve it before we start. No surprises halfway through the job.
- We remove the old lock, fit the new one, align the latch and bolt with the strike plate, and test the door open and closed several times, with the door both ajar and fully shut.
- We hand over the keys, cut extra copies if you want them, and show you how the lock operates. You are welcome to keep the old hardware.

Call (213) 577-1366Front door, house and apartment lock replacement
Front door lock replacement is the most common request we get. A typical entry door has two pieces of hardware: a handle or knob set, and a separate deadbolt. We usually suggest replacing them as a matched pair so they use one key, instead of leaving you with two keys on the ring and one lock that is far older than the other.
House lock replacement for a whole home follows the same idea on a larger scale. You can have front, back and side doors keyed alike, so one key opens everything. Or you can keep certain doors separate, such as a shed, garage entry or guest room. We will lay out those options before we start, because the keying plan is a decision that is easy to make now and annoying to change later.
If a lock is already broken, our job is first to get the door secure again. When you need to replace a broken lock after a failed key, a forced entry or a handle that came off in someone's hand, we deal with the damage to the door as well as the lock. If the door has no deadbolt at all, adding one is covered on our deadbolt installation page.
Apartment lock replacement has one extra step: permission. Tenants should check their lease and talk to the landlord or manager before changing the hardware, and landlords or property managers can call us to replace locks between tenants. In small apartment buildings we can often work through several units in one visit when the manager has arranged access.
What does a security lock upgrade involve?
A security lock upgrade means replacing a lock with something harder to defeat, not just something newer. The things that matter are how well the cylinder resists picking and drilling, how solid the bolt is and how far it extends into the frame, and how the lock is anchored to the door.
In our experience, the door and frame are often the weak link rather than the lock. A good deadbolt held by short screws into a thin strike plate will not stand up to a hard kick. So an upgrade usually includes a reinforced strike plate with long screws that reach the framing, and sometimes reinforcement around the latch area of the door. For people who want controlled key duplication or more pick resistance, see our page on high-security locks.
If you are thinking about keypad or app-based hardware, tell us when you call. Not every door and not every household suits it, and we will say so plainly.

Call (213) 577-1366Commercial and business lock replacement
Commercial lock replacement is a different job from a house door because the hardware, the traffic and the risks are different. Business doors get opened dozens of times a day, and storefront hardware can wear out much faster than anything on a residence. Business lock replacement often involves aluminum-and-glass storefront doors, mortise cylinders, rear service doors and sometimes interior office doors.
A business security upgrade usually starts with a short walk-through: which doors matter most, who holds keys, and what happens when an employee leaves. Rekeying or replacing the cylinders on a schedule that fits staff turnover is one of the simplest ways to tighten a small business's security. Some doors also have to open from inside without a key, so we check that the hardware we install suits how the door is actually used.
If your storefront lock is sticking or damaged rather than due for replacement, our storefront lock repair page may be the better place to start. We will tell you honestly if a repair is enough.
What affects the cost of lock replacement?
We do not quote prices on a web page, because the real answer depends on your door. What we can do is tell you exactly what moves the cost up or down, so the quote we give you over the phone or on site makes sense.
- The grade and brand of lock. A basic residential knob and a heavy-duty commercial deadbolt are different products at different cost.
- How many locks. Replacing and keying several doors alike takes more hardware, though it is often more economical per door than doing them separately.
- The condition of the door and frame. A swollen edge, a worn strike plate or a bore hole that is too large for the new lock adds work.
- Whether the door needs reinforcement as part of a security upgrade.
- The type of lock. Mortise locks, smart locks and high-security cylinders cost more than standard hardware.
- Extra keys and special keying such as keyed-alike sets or restricted blanks.
- When and where you need us. Late-night calls and a longer trip to reach your door can affect the quote, and we will explain that up front.
Lock replacement in Fillmore: bungalows, new tracts and ranch gates
Fillmore is overwhelmingly single-family housing, and the age of the house usually decides what the replacement job looks like. Downtown Fillmore around the Central Avenue district has early-1900s bungalows and 1920s to 1940s cottages. Old doors there can have unusual bore sizes, thick wood and vintage hardware that was never meant to be swapped for a modern lock without some adjustment. Our approach is to check whether the original hardware can be kept in service. If it cannot, we fit a new lock that suits the door without butchering it.
Fillmore sits inland, with hot, dry summers. Heat can swell wood doors and frames in older homes, so a lock that bound up in August can feel fine in winter, and a replacement lock will not fix a door that rubs. We look at that during the inspection. Valley dust also works its way into exterior lock mechanisms over time, which is one reason a worn front door lock in 93015 can start failing even when it was good hardware once.
On the north side, Heritage Grove has added newer tract homes. For those, the typical request is different: new owners who want fresh locks or a security lock upgrade, sometimes alongside a rekey. Ring a lock replacement in North Fillmore and Heritage Grove a decision about whether the builder-grade hardware is worth keeping or worth upgrading.
Around Bardsdale and the valley floor, many properties are citrus ranches with outbuildings and gates. A lock that guards a packing shed or equipment barn faces weather, dust and heavy use. If the problem is a damaged gate latch or chain-lock setup, our gate lock repair page covers it. For the main house and outbuildings, replacement with weather-appropriate hardware is often the better long-term fix.
Along Central Avenue, shops and small offices face the commercial side of this same job: worn storefront cylinders, doors that were rekeyed many times and finally need new hardware. We are based in Westwood, roughly 55 miles away, so we tell you honestly when you call what the arrival window looks like instead of promising one we cannot keep.

Call (213) 577-1366Why call Wilshire Lock & Key for lock replacement?
We have been in business since 1987, and we serve 140 cities across Los Angeles and Ventura counties, Fillmore included. We have a storefront at 10740 Wilshire Blvd in Westwood and mobile service vans that come to you, so you are dealing with one company rather than a call center passing your job to whoever is free.
David, the owner and lead technician, oversees the work. You will not be bounced through a dispatch middleman who has never seen the lock you are describing. The person who answers the phone at (213) 577-1366 can get you a straight answer about replace, rekey or repair, at any hour of any day.
We would rather talk you out of an unnecessary replacement than put in hardware you did not need. If the honest answer is a rekey or a small adjustment, that is what we will tell you.
What should you ask any locksmith before they start?
California requires locksmith companies to hold a BSIS LCO license, issued by the Bureau of Security and Investigative Services. Ask any locksmith for that license number before work begins, and check it with the state. It is a fair question and a good company will answer it without fuss.
Ask also for the full cost explanation before the work starts, what brand and grade of lock will go in, and whether the old hardware comes back to you. Be careful with anyone who will not describe the job until they arrive, or who changes the story once the old lock is out. Those questions apply to us as well, and we welcome them.
Frequently asked questions
How do I know whether I need a new lock or just a rekey?
If the lock works smoothly and looks sound but you are worried about who has keys, a rekey is usually enough and usually the more economical route. If the lock is damaged, forced, worn out or loose, replacement is the better fix. We look at it and tell you which.
Can you replace a lock at night or on a weekend in Fillmore?
Our phone at (213) 577-1366 is answered 24 hours a day, 7 days a week, year-round. Call any time and we will talk through the job. Because Fillmore is about 55 miles from our Westwood base, we will give you an honest arrival window on the call rather than a guess.
Will the new lock work with my existing keys?
Usually not, since a new lock comes with its own keys. If you want one key for the front door and back door, we can key the new locks alike. If you want to keep using an existing key, tell us up front and we will say whether that is possible.
Can you replace just the deadbolt, or do I have to do the whole door?
We can replace only the deadbolt, only the handle set, or both. We often suggest doing both as a matched pair so they share a key and the finish matches, but it is your choice and the door's condition will guide us.
My wood door sticks in summer. Will a new lock fix it?
Probably not on its own. In Fillmore's hot, dry summers, heat can swell wood doors and frames, and that rubbing is a door and frame issue. We check alignment and the strike plate during the visit, and if a new lock is not the answer, we will say so.
I rent an apartment. Can I have the lock replaced?
Check your lease and talk to your landlord or property manager first. Many require permission or a copy of the key. If the manager approves, we can do the replacement. Landlords and managers can also call us to replace locks between tenants.
Do you replace locks for businesses and storefronts?
Yes. We handle business lock replacement and business security upgrades, including storefront cylinders, rear doors and interior office doors. We also look at keying, who holds keys and whether doors must open from inside without a key.
What affects the cost of replacing a lock?
The grade and type of lock, how many doors you are doing, the condition of the door and frame, any reinforcement, extra keys or special keying, and the time and distance of the visit. We explain the quote before work starts and you approve it first.
Is a locksmith required to be licensed in California?
Yes. California requires locksmith companies to hold a BSIS LCO license. Ask any locksmith for the license number before they start work and verify it with the state.
