Should you rekey or replace when you change your locks?
Most people who search for a lock change service are really asking one question: do I need brand-new locks, or do I just need the old ones to stop working for anyone else who holds a key? That is the first thing we sort out on every call, because the answer decides the work, the time on site, and the cost.
Changing locks is an umbrella term. It can mean rekeying, where we reset the inside of your existing cylinders so they work with a new key and every old key becomes useless. It can mean replacing, where we remove the lockset and fit a new one. And often it is a mix: rekey the front door because the hardware is fine, and replace a worn deadbolt on the back slider or garage entry. Neither approach is automatically better. If you want the details on each, we have separate pages on lock rekeying and lock replacement.
The short version: if your hardware is sound and you like it, rekeying is usually the more economical route. If it is worn, loose, mismatched, or you simply want something stronger, replacing makes more sense. We will tell you which one applies to your doors and why before any work starts, so you are never guessing.
Why do people change their door locks?
The reasons are more ordinary than dramatic. Nobody is usually in danger; they just do not know who else has a key. Here are the situations we see most often when a Westlake Village homeowner or renter calls for a lock change:
- You bought a house and have no idea how many copies the previous owner, their agent, a cleaner, a contractor, or a neighbor still holds.
- You are moving into a rental or a townhome and want the locks to be yours, not a previous tenant's.
- A key was lost or stolen, or a bag with your keys and address in it went missing.
- A relationship ended, a roommate moved out, or a house-sitter or caregiver no longer needs access.
- Your locks are old, stiff, sticking, or visibly worn, and you would rather fix them properly than keep fighting them.
- You want every exterior door on one key instead of carrying a ring that looks like a janitor's.
- You are upgrading, perhaps to a stronger deadbolt or an electronic lock, and want the old hardware dealt with at the same visit.
How does a lock change work, step by step?
There is nothing mysterious about it, and you are welcome to watch. A typical lock change at a home goes like this:
- You call (213) 577-1366. A person answers, whatever the hour. We ask what happened, how many doors are involved, and whether you already know if you want rekeying or replacing.
- We come to you in one of our mobile vans. If you would rather stop by, our storefront is at 10740 Wilshire Blvd in Westwood, though most Westlake Village customers prefer we come to the door.
- We confirm you live there or have the authority to change the locks. This is routine for any reputable locksmith and it protects you as much as anyone.
- We look at every exterior lock: front door, back and side doors, garage entry, sliders with keyed latches, and any deadbolts. We check condition, brand, fit, and how the door and frame are holding up.
- We lay out the options in plain terms: rekey these, replace those, and why. You decide. No pressure to replace something that does not need it.
- We do the work. Rekeying means removing cylinders, changing the internal pins to match new keys, and putting them back. Replacing means removing the old set and installing the new one, with the strike plate and screws checked so it actually seats properly.
- We test every lock with the new keys, with the door open and closed, and confirm the old keys no longer operate the rekeyed cylinders.
- We hand over the new keys and, if you want extras, we cut them on site. If you need more copies later, we do key duplication at the storefront too.

Call (213) 577-1366How do you choose between rekeying and replacing?
Here is how we think about it at the door. It is a judgment call, and it depends on what is physically there, not on what is more profitable for us.
- Rekey when the lock is in good working order, turns smoothly, and you are happy with how it looks. The goal is only to cancel old keys. It is also a good fit when you want several doors to share one key.
- Replace when the lock is worn, loose in the door, hard to turn, damaged, or finish-faded to the point it looks tired. Replace as well when the lock is an unknown or very low-grade unit you would not trust.
- Replace when you want to upgrade the level of protection, for example a heavier deadbolt, a better strike plate arrangement, or a smart lock.
- Mix the two when doors differ. A solid, well-kept front lockset can be rekeyed while a failing back-door deadbolt gets swapped out.
- Keep in mind that some very old or unusual locks cannot be rekeyed neatly, or are not worth the effort. We will say so honestly when that is the case.
What affects the cost of a lock change?
We do not quote numbers on a web page because the real price depends on your actual doors, and anyone who gives a flat figure without seeing them is guessing. What moves the cost, in plain terms:
The number of locks matters most. A lock change on one door is a different job than a house with a front door, two deadbolts, a garage entry, and a patio door. Rekeying is generally priced by the cylinder, while replacement adds the cost of the hardware itself.
Rekey versus replace is the next big factor. Rekeying reuses what you have, so it is usually the lighter-cost option. Replacement brings in new locksets, and the grade and finish you choose change the total considerably. A basic builder-grade lockset and a high-security deadbolt are very different products.
Brand and condition of the existing lock matter too. Some hardware rekeys easily; some needs special parts or more time. If a door is out of alignment or the frame is damaged, fixing that to make the lock work properly is part of the job.
Timing and location play a role as well. A scheduled visit during the day is a different situation from a late-night emergency call, and Westlake Village is a drive for our vans from the Westwood storefront, about 32 miles. We will tell you how the call is being priced before we begin, not after.
Finally, any extras: additional keys, keying several doors alike, or having us haul away the old hardware. Ask us and we will explain each one.

Call (213) 577-1366Changing locks after buying a house in Westlake Village
If you have just closed on a home here, changing the locks should be on the first-week list, ahead of unpacking boxes. Westlake Village was master-planned from the late 1960s around its man-made lake, and most of the city's homes are single-family tract houses from the 1960s through the 1980s. Houses that old have usually had several owners, and each one handed out keys. Nobody can tell you how many copies exist, which is exactly why a lock change after a purchase is worth doing.
Age matters in a second way. In older tracts such as First Neighborhood and Foxmoor Hills, original 1960s and 1970s door hardware still survives in some homes. Those locks may still turn, but after decades the internal parts are worn, the finishes are tired, and the cylinders are often a lower grade than what you would choose today. In these homes we often recommend replacing the front and rear deadbolts outright rather than rekeying a lock that is already near the end of its life. If an older lock is still solid, we will say so and rekey it.
On Westlake Island, the lakefront homes sit behind a gated bridge entrance. That gate is not something we change as part of a house lock change, but the doors of the home itself are. Rekeying a lakefront house is often a clean, quick job when the hardware is good, and it means the previous owner's keys, and any copies floating around, stop working. Stuck, locked out of your own new house? That is a different call, and our page on house lockouts covers it.
Many Westlake Village homes fall under HOAs, so it is worth a quick look at your association's rules before choosing a new finish for visible exterior hardware. We can work with you on finish and style, and rekeying avoids the question completely because the lock looks exactly as it did before.
Climate plays a minor role. The Conejo Valley gets some marine influence, but summers are warm and dry, with Santa Ana wind events, and the main effects on door hardware are sun exposure and modest seasonal wood movement. Sun fades and dries finishes on south- and west-facing doors, and wood doors can swell or shrink slightly through the year, which sometimes makes a bolt bind or a latch rub. When we change a lock we check the alignment so it works smoothly in both seasons.
Everything above applies to ZIP code 91361, whether your home is in Three Springs, Southshore Hills, Trentwood, Hidden Canyon, Triunfo Corner, Village Homes, or one of the others. Neighbors nearby in North Ranch, on the Thousand Oaks side, and Lake Sherwood, in unincorporated Ventura County, are also within our service area. The broader Westlake Village community straddles the county line, so if your address is on either side, the lock work is the same.

Call (213) 577-1366Townhomes, condos, and lock changes near the lake
Condos and townhomes cluster near the lake and Agoura Road, and the lock change questions are a bit different. Often you control your own entry door, but not necessarily the building's shared doors or gates, and your HOA may have rules on exterior hardware or on who may hold keys. Check before you buy new locks if your door faces a common area. A rekey keeps the hardware identical, which is usually the simplest path in a managed community.
If you own a rental, the same logic applies each time a tenant leaves: the locks should be changed or rekeyed before the next person moves in. Our page for landlords covers that kind of ongoing work.
Nearby commercial spaces are a separate world, whether it is the offices along Lindero Canyon Road or the restaurants and shops around The Landing at Westlake. That work is covered under our commercial pages, not here, but the principle is the same: when staff or tenants change, the keys should change too.

What should you ask any locksmith before they change your locks?
Whoever you hire, ask a few questions first. California requires locksmith companies to hold a license from the Bureau of Security and Investigative Services, known as a BSIS LCO license. Ask for the license number and look it up on the state's lookup tool. A real company will give it to you without hesitation.
Ask how the price is determined and what it will include before anyone starts working. Ask whether they will rekey or replace, and why. Be wary of anyone who immediately says everything must be drilled and replaced, or who will not explain the options.
Ask who will be coming to your door and which company they work for. And ask what you will get at the end: how many keys, whether old keys are cancelled, and what happens if something does not work the next day.

Frequently asked questions
Do I need to change the locks after buying a house in Westlake Village?
It is strongly recommended. You cannot know how many copies of the old keys exist. Most homes here are 1960s to 1980s tract houses that have changed hands several times, so a lock change or rekey in the first days of ownership is a sensible precaution.
Is it better to rekey or replace my locks?
It depends on the lock. If the hardware is in good shape and you like it, rekeying is usually the more economical route. If it is worn, damaged, or you want something stronger, replacing is better. We look at your doors and give you an honest recommendation before starting.
Can you rekey the original 1960s or 1970s locks in older Westlake Village homes?
Sometimes. If the lock still works smoothly and the cylinder is rekeyable, yes. But after decades of use, many original locks are worn enough that replacing them is the better choice. We tell you which applies after inspecting each door.
How long does it take to change the locks on a house?
It depends on how many doors there are and whether we are rekeying or replacing. A single door is quick; a whole house with several deadbolts takes longer. We will give you a realistic idea once we have seen the doors, and we do not rush the testing at the end.
Will my old keys still work after a lock change?
Not on the locks we rekey or replace. That is the point of the job. After rekeying, only the new keys operate the cylinders. We test this before we leave. Any lock we did not touch will, of course, still work with its old key.
Can you change locks on weekends, nights, or holidays?
Yes. Our phone at (213) 577-1366 is answered 24 hours a day, 7 days a week, all year. Be aware that how and when a call is scheduled can affect cost, and we will explain that before we begin.
Do I have to prove I live at the property?
We will ask you to confirm that you live there or have the authority to change the locks, such as an owner, a tenant, or a property manager. It is a normal step any responsible locksmith takes, and it protects you too.
Will my HOA care if I change my locks?
Many homes here are in HOAs. Rules vary, mostly regarding the visible look of exterior hardware. Rekeying leaves the hardware looking the same, so it rarely raises questions. If you are replacing visible hardware, check your association's guidelines first.
Can you change all my locks to use one key?
In most cases, yes. We can rekey multiple locks to work with the same key, or fit new locks keyed alike. Some older or unusual hardware may not cooperate, and we will tell you if that is the case.
How do I know you are a legitimate locksmith company?
Ask any locksmith, including us, for their California BSIS LCO license number and check it. You can also see that we operate from a real storefront at 10740 Wilshire Blvd, Los Angeles, CA 90024, and we have been in business since 1987.
