Rekey or replace: what does it mean to change your locks?
When people say they want to change the locks, they usually mean one of two different jobs. The first is rekeying: we keep your existing lock hardware and rebuild the inside of the cylinder so the old keys stop working and a new key takes over. The second is replacement: we remove the old hardware and install new locks. Either one shuts out every key that was in circulation before. Which one makes sense depends on the condition of what is on your door, how you want it to look, and what you want it to do.
We would rather talk you through the choice than sell you the bigger job. If your locks are sound, rekeying is usually the more economical route and the quicker one at the door. If the hardware is worn, loose, mismatched, or simply not what you want guarding your home, replacement is the honest answer. This page covers how that decision gets made and what a lock change at your Agoura Hills home actually involves.
When should you change your locks?
The most common reason we hear is a move. You get keys at closing or from a landlord, but nobody can tell you how many other keys exist. Beyond that, these are the situations where a lock change is worth doing rather than putting off:
- You bought a house, townhome, or condo and have no idea how many copies were made over the years by previous owners, agents, contractors, cleaners, or neighbors.
- You moved into a different home and want every exterior door on a key you control.
- A key was lost or stolen, especially if it was on a ring with anything that shows your address.
- A roommate, partner, or family member moved out and still has a key.
- A contractor, house sitter, caregiver, or former employee had access and the job is finished.
- The hardware is failing: keys stick, the cylinder is rough, the deadbolt drags, or the knob wobbles.
- Your front door, back door, and side door each take a different key and you are tired of carrying a bundle.
How do we change your locks, step by step?
The process is the same whether it is one door or a whole house. Here is what happens from the first call to the last key handed over.
- You call (213) 577-1366. Tell us how many exterior doors you want done, what kind of locks are on them if you know, and whether you are also locked out. Photos of the locks help, but they are not required.
- We send a mobile van to your address. You do not have to bring anything to our Westwood storefront at 10740 Wilshire Blvd.
- We look at each lock before touching anything: brand, age, wear, and whether the cylinder can be rekeyed cleanly. We also check how the door closes, because a lock is only as good as the alignment behind it.
- We lay out the options in plain terms for each door. Rekey this one, replace that one, and why. You decide before any work starts, and we explain what the job will cost before we begin.
- We do the work. That means rekeying the cylinders to a new key, or installing new hardware fitted to your door, latch, and strike plate.
- We test every lock with the new keys, with the door open and closed, and check that the latch and deadbolt move fully and smoothly. A lock that works open-handed but binds when the door is shut is not finished.
- We hand over the keys, tell you exactly how many are in existence, and talk through spares. If you need extra copies, key duplication is easy to add on the same visit.

Call (213) 577-1366How do you decide between rekeying, replacing, and upgrading?
Here is how we think it through at your door. None of this is a sales script; sometimes the lighter-cost option is plainly the right one, and sometimes it is not.
Rekeying works on most standard pin-tumbler cylinders in decent shape. It keeps your existing finish and style, which matters if you like the look of what you have, or if you live under an HOA and do not want visible changes. It also lets us put several doors on one key. It is not a good choice when the cylinder is badly worn, when parts are damaged, or when the lock is low-grade enough that you would be paying to improve something you would replace anyway. We will tell you when we see that.
Replacement is the right call when hardware is loose, corroded, mismatched, or broken, or when you simply want a better lock. It is also where the door itself comes into play. A new lock on a door with a weak strike plate or short screws into the frame still leaves the weak point where it was, so we check that while we are there.
Upgrading is a separate decision from changing locks, but a move is a natural time to make it. If a door has only a knob lock and no deadbolt, deadbolt installation adds a second layer. If you want codes or phone access instead of carrying keys, smart lock installation is worth considering, though a smart lock still needs a well-fitted door and sound mechanical hardware behind it. We will tell you honestly whether a smart lock suits a particular door.
- Rekey when the hardware is sound and you mainly want old keys dead.
- Replace when the hardware is worn, damaged, mismatched, or not what you want.
- Upgrade when a door lacks a deadbolt, or you want keyless access.
What affects the cost of changing locks?
We do not put numbers on a web page, because the real figure depends on your doors and not on an average. What moves the cost up or down is fairly predictable:
- How many locks you want changed. Every cylinder adds work, though a multi-door visit spreads the fixed part of the trip across more doors.
- Rekey versus replace. Rekeying generally costs less than new hardware, but only when the existing locks are worth rekeying.
- Hardware grade and brand. Standard builder-grade locks and high-security cylinders sit in very different places. If you are interested in the higher end, see our page on high-security locks.
- Finish and style matching. Matching a particular finish across several doors can affect which hardware we use.
- Door and frame condition. Misaligned latches, worn bores, or damaged strike areas can add repair work before a new lock will behave.
- Keying choices. Keyed-alike setups, restricted keyways, and extra keys all change the work involved.
- Timing and travel. A night or holiday call is different from a weekday daytime visit, and Agoura Hills is about 28 miles from our Westwood storefront.

Call (213) 577-1366Changing locks in Agoura Hills: tract homes, HOAs, and canyon weather
Most of the homes in Agoura Hills are 1960s through 1980s ranch and two-story tract houses built as the Ventura Freeway corridor grew, with townhomes and condos near Kanan Road and Thousand Oaks Boulevard. That age matters for a lock change. A house that has passed through several owners over several decades has had plenty of chances for keys to be copied and forgotten. If you just bought in Morrison Ranch or Lake Lindero, both in ZIP code 91301, the original builder-grade hardware may still be on the door, and no one can tell you how many keys are out there. Rekeying the whole house to one new key is often the sensible first step before the moving boxes come in.
Several Agoura Hills neighborhoods, including Lake Lindero and Morrison Ranch, operate under homeowners associations. Some HOAs have guidelines about exterior door hardware and finish, so check before replacing anything visible from the street. Rekeying leaves the look of your locks exactly as it is, which makes it an easy path in those communities. Other neighborhoods in town, such as Liberty Canyon, Fountainwood, Forest Cove, Hillrise, and Annandale, have their own mix of tract homes and townhomes, and we handle the same decision at each door: sound hardware gets rekeyed, tired hardware gets replaced.
The climate shows up in lock work here. Agoura Hills is an inland valley next to the Conejo Valley, with hot, dry summers, strong Santa Ana winds, and big temperature swings between day and night. Wood doors and frames move with the seasons. A lock that sticks in one month and works fine in another is often a door that has shifted, not a bad lock, and putting a new lock on a door that rubs will only give you a new lock that binds. We check alignment and the strike plate as part of a change, so the lock you install keeps working through the seasons.
Agoura Hills also sits in a wildland-urban interface, and some homes there were rebuilt after the 2018 Woolsey Fire. If you are taking over a rebuilt house, or one where contractors have worked for months, think about how many people held keys during construction and finishing. Changing the locks after the last trade leaves is a simple way to start clean. In Old Agoura, larger equestrian lots and older rural homes often have a gate and barn on top of the house doors. We can rekey or replace the house locks on those properties as a lock change job, while gate and barn hardware is a different kind of work.
And if you are moving into a townhome near Whizin Market Square and discover you are locked out with a van full of furniture, that is a lockout first and a lock change second. Our house lockout service gets you inside, and we can rekey or replace the lock on that same visit once you are in.

What should you ask any locksmith before they change your locks?
Ask the same questions of us that you would ask of anyone. California requires locksmith companies to hold a BSIS LCO license, issued by the Bureau of Security and Investigative Services, and you should ask any locksmith for it before they start working on your home. Be wary of a company that will not give its legal name and address, or that answers the phone with a generic greeting instead of a business name.
Also ask what exactly they plan to do to each lock, whether it is a rekey or a replacement, and what that will cost before work begins. Be cautious of a very low advertised service fee that grows once someone is standing at your door. A reputable locksmith will explain the work first and expect you to agree to it.
What should you have ready when you call?
A little preparation makes the visit faster and the quote more accurate:
- The address and which doors you want done: front, back, garage side door, patio slider, or others.
- Photos of the locks, or a note of whether each has a knob, a deadbolt, or both.
- Any keys you currently have, so we can tell you what to expect.
- A note of whether you are under an HOA and whether it has hardware rules.
- Whether you want everything on one key, and how many copies you would like.
- Proof that you live at the property, since a locksmith should confirm that you are entitled to have the locks changed.
Frequently asked questions
Should I change the locks when I buy a house in Agoura Hills?
Yes, it is one of the most common reasons people call us. You cannot know how many keys previous owners, agents, or contractors made over the years, especially in tract homes that have changed hands over several decades. Rekeying or replacing before you settle in puts you in control of every key.
Is rekeying as secure as installing new locks?
For a lock in good shape, rekeying gives you a fresh key and shuts out all the old ones, so it addresses the main concern after a move. It does not make the lock stronger than it was. If the hardware is low-grade or worn, replacing it gives you better protection, and we will say so at the door.
Can all my doors be put on the same key?
Usually yes. When the locks are compatible, we can rekey or select hardware so the front door, back door, and other exterior doors work with a single key. Some older or unusual locks may not allow it, and we will let you know after we look at each one.
How long does a lock change take?
It depends on the number of doors and whether we are rekeying or replacing. A single rekey is a quick job, while a whole house with replacement hardware takes longer. If a door needs alignment work, that adds time. We will give you a realistic sense of it after looking at your locks.
Do I need HOA approval to change my locks in Lake Lindero or Morrison Ranch?
Both neighborhoods have HOAs, and some associations have guidelines on exterior door hardware. We cannot speak for any specific association, so check yours before replacing visible hardware. Rekeying keeps the same hardware, so it generally avoids the question altogether.
Can you change my locks if I am locked out of my new home?
Yes. We get you inside first, then rekey or replace the lock once the door is open. Doing both on the same visit saves a second trip, and you do not have to let the old keys stay in circulation.
Do you change locks at night or on weekends?
Our phone line is answered 24 hours a day, 7 days a week, year-round, at (213) 577-1366. If you are moving in late or discover a problem on a holiday, call and we will tell you what we can do.
My lock sticks more in summer. Does it need replacing?
Not necessarily. Agoura Hills has hot, dry summers and big day-night temperature swings, and wood doors and frames shift with the seasons. A sticking lock can be a door that has moved and a latch or strike that no longer lines up. We check alignment first, since a new lock on a rubbing door will bind too.
Do I need to be home while you change the locks?
Someone with the authority to approve the work should be there, at least at the start and end. We need to confirm you are entitled to have the locks changed, agree on the work, and hand the new keys to you directly.
