What does it mean to change locks?
When people say they want to 'change the locks,' they usually mean one of three different jobs, and the difference affects both your security and your bill. Sorting it out at the start is most of what a good locksmith does on the phone.
The first job is rekeying. We take the lock apart, change the internal pins so it works with a new key, and put it back on your door. The hardware stays, the old keys stop working, and you get new keys cut to the new pattern. The second job is replacing, where the lock itself comes off and a different one goes on. The third is a mix: some doors get rekeyed because the hardware is sound, and others get replaced because it is worn, damaged, or simply not the kind of lock you want protecting your home.
A lock change is not a repair and it is not an emergency entry. If you are standing outside a locked door, that is a different call, and our house lockout service in Fillmore covers it. This page is about the planned or semi-planned situation: you have access, and you want to be sure nobody else does.
Should you rekey or replace your locks in Fillmore?
This is the question we get most, and the honest answer is that rekeying is usually the more economical route when the existing locks are in good shape. A decent deadbolt or knob set does not stop being decent because someone else once held a key to it. If the hardware works smoothly and you simply need different keys, lock rekeying is typically what we recommend.
Replacement makes more sense when the lock itself is the problem. We look at the hardware in your hand before we suggest anything, and we will tell you plainly if rekeying is the sensible call, even though it is the smaller job.
- Rekey when the locks are in good working order, the finish is fine, and your goal is simply to cut off old keys.
- Replace when a lock is worn, sticks, spins loosely, shows damage from a past break-in attempt, or is a basic builder-grade piece you would rather upgrade.
- Replace when you want a different feature, such as a keypad, a higher-security cylinder, or a matching set of finishes across every door.
- Replace when the lock is an unusual or discontinued model that cannot be rekeyed reliably.
- Do a mix when your doors vary: some rekeyed, a few swapped, all keyed alike so you carry one key.

Call (213) 577-1366Why change locks after buying a house or moving in?
When you buy a house, you do not know how many keys exist for it. The previous owner may have given copies to family, a house cleaner, a neighbor, a contractor, or a dog walker, and may not remember. The same is true of a rental you move into, or a place you share after a roommate leaves. Nobody has to be untrustworthy for this to be a problem. A key you cannot account for is simply a key you cannot control.
That is why changing locks after buying a house is one of the first things we suggest to new owners, ideally before the first night or as close to it as you can manage. It is also a clean way to start: you hold every key, you know exactly how many were made, and you can decide who gets one.
The same logic applies in other life changes. After a separation, after a roommate moves out, after an employee or helper who had a key leaves, after a lost or stolen set of keys, or after a break-in, new keys are the sensible response. If you are a landlord handling turnover, our locksmith for landlords page is the better starting point, but the principle is the same.
How we change your locks, step by step
Here is how a typical lock change goes, whether you are a new homeowner or just tired of wondering who has a key. The details shift with your doors, but the order stays the same.
- You call (213) 577-1366, any hour. We ask what kind of doors you have, how many, whether you have all the current keys, and what is prompting the change. Photos of the locks, if you can text them, help us bring the right parts.
- We tell you what we expect, rekey, replace, or a mix, and what will affect the cost, so there is no surprise on arrival. Fillmore is roughly 55 miles from our Westwood storefront, so these phone questions matter: we want the van loaded correctly before it leaves.
- On site, we look at each lock in person: how it turns, whether it is loose, how the bolt meets the frame, and whether the door itself is sitting true.
- We confirm the plan with you. If something we saw changes our recommendation, we say so before touching anything.
- We do the work: rekeying cylinders, installing new hardware, or both. We test each lock with the door open and closed, because a lock that works open can bind once the door is shut.
- We cut and test your new keys, and we make sure every lock you wanted keyed alike really does work with one key.
- We walk you through what we did and explain which old keys no longer work. If you want extra copies, we can handle key duplication at the same visit.

Call (213) 577-1366What affects the cost of a lock change in Fillmore?
We do not quote numbers on a web page, because an honest number depends on your actual doors. What we can do is tell you exactly what moves the cost up or down, so you can judge any quote you receive from us or from anyone else.
- How many locks. A single front door is a different job from a house with front, back, side, garage entry, and a gate.
- Rekey versus replace. Rekeying is generally the lighter-cost option when the hardware is sound. New hardware adds the cost of the lock itself.
- The grade and type of hardware. Basic knob sets, solid deadbolts, high-security cylinders, and electronic locks sit at very different points.
- Keyed alike or not. Setting every lock to one key is common and sensible, but it takes a little more work on mixed hardware.
- The number of keys you want cut.
- The condition of the doors and frames. A door that has swollen or dropped may need adjustment before any lock will work well on it.
- When and where you call. After-hours and out-of-area work involves different time and travel than a daytime scheduled visit.
- Special items such as keypad or smart locks, which add setup and programming.
Changing locks in Fillmore: Heritage Grove, Central Avenue, and the ranches
Fillmore is mostly single-family housing, and the right lock change depends heavily on which part of town you are in. ZIP code 93015 covers a wide mix, and we treat each type of home differently.
In Heritage Grove on the north side, the newer tract homes are the classic case for a first-week rekey. Builders and their crews can hold keys during construction and finishing, and the locks installed are usually standard builder hardware in good condition. For most of these homes, rekeying every exterior door to one new key is the sensible approach, and we can upgrade a deadbolt or two if you want more than the basics. If you are thinking about adding a keypad or app-controlled lock, see our smart lock installation page.
Around Downtown Fillmore and the Central Avenue district, the early-1900s bungalows and 1920s to 1940s cottages are a different story. The original hardware may be vintage, and some of it is worth keeping. We look first at whether an old mortise or rim lock can be rekeyed or serviced rather than ripped out. Summer heat can also swell wood doors and frames in older homes, which makes a lock bind or a deadbolt fail to throw cleanly. If a new lock seems to stick in August, the door is often the cause, and we check that before blaming the hardware. If the problem is the lock itself and not a change, our lock repair page explains that side.
Out toward North Fillmore and the edges of town, many homes are postwar single-family houses with a mix of original and replaced hardware. Valley dust works into exterior lock mechanisms over time, so older locks that feel gritty may be better replaced than rekeyed.
On the citrus ranch properties around Bardsdale and the valley floor, a lock change often means more than the house door. Outbuildings, sheds, and gates may all share keys that have passed through many hands over the years. We can bring all of these onto a single plan, and for the gates themselves, our gate lock repair page covers the mechanical side.

Call (213) 577-1366Why call Wilshire Lock & Key for a lock change?
We have been in business since 1987, and we serve 140 cities across Los Angeles and Ventura counties, Fillmore among them. We run a storefront at 10740 Wilshire Blvd in Westwood plus mobile service vans. When you call (213) 577-1366, you reach us, not a dispatch middleman who sells the job to whoever is available. The company that answers is the company that shows up.
David, the owner and lead technician, oversees how we work. That matters on lock changes in particular because the decision of rekey versus replace is a judgment call, and we would rather make it with your interests in mind than push the larger job.
One more thing worth knowing: California requires locksmith companies to hold a license from the Bureau of Security and Investigative Services, known as a BSIS LCO license. Ask any locksmith for that license number before they start work, including us. It is a fair question and a good habit.
What to have ready before you call
A few details make the phone call quicker and the visit smoother. None of this is required, and if you do not know something, say so and we will figure it out on site.
- How many exterior doors, plus any gates, garage entry doors, or outbuildings, you want included.
- Whether you want one key for everything or different keys for different doors.
- Any current keys you still have, since we can work from them.
- A photo of each lock, especially if it looks old or unusual.
- Whether any lock is currently sticking, loose, or damaged.
- Whether you are leaning toward rekeying or replacing, and why. If you are unsure, that is fine; helping you decide is part of the job.
Questions to settle before the lock change
Most Fillmore customers have the same few concerns, and they are worth settling in advance. Do you want a keypad or smart lock on one door while the rest stay keyed? Would you like your mailbox, side gate, or shed keyed the same? Will anyone else, such as a tenant, relative, or house helper, need their own key? A few minutes thinking about those answers means you pay for the work you actually want, once, and do not need a second visit.
Frequently asked questions
Should I change my locks right after buying a house in Fillmore?
Yes, as early as you reasonably can. You cannot know how many copies of the old keys exist, and new keys put control back in your hands. For most newer homes, rekeying is enough. Call (213) 577-1366 and we will tell you what makes sense for your doors.
What is the difference between rekeying and replacing locks?
Rekeying changes the inside of the existing lock so it works with a new key and old keys stop working. Replacing removes the lock and installs a different one. Rekeying is usually the more economical route when the hardware is in good shape; replacing makes sense when it is worn, damaged, or you want a different type of lock.
Can you change locks the same day I call?
We answer the phone 24 hours a day, 7 days a week, and we will give you an honest arrival window when you call. Because Fillmore is about 55 miles from our Westwood storefront, we ask a few questions first so the van carries the right parts.
Do I need new keys for every door, or can they all match?
They can all match. Setting every exterior lock to one key is common and works well on most homes. Mixed hardware may take a little more work to key alike, and we will tell you if a particular lock is better replaced than rekeyed.
Can old Central Avenue bungalow locks be rekeyed?
Often, yes. Early-1900s and 1920s to 1940s homes may have vintage hardware that is worth keeping, and many of those locks can be rekeyed or serviced. If a lock is too worn or no longer works properly, we will say so and discuss replacement. See our lock replacement page for what that involves.
Will a lock change work on a sticking wood door?
Only if the door is not the problem. Summer heat can swell wood doors and frames in older homes, which makes any lock bind. We check how the door sits before deciding, because a new lock on a swollen door will still stick.
Can you upgrade a deadbolt while you change the locks?
Yes. Many people rekey the existing knob sets and upgrade only the deadbolt on the main entry. Our deadbolt installation page explains the options, and we can handle both in a single visit.
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 the number before work begins and check it with the state if you want to be sure. It is a reasonable request from any customer.
