Should you rekey or replace when you change locks?
Changing locks is a goal, not a single product. What you actually want is for keys you don't control to stop working on your doors. There are two ways to get there, and part of our job is telling you honestly which one suits the door in front of us.
Rekeying keeps the existing lock body and changes the small internal parts inside the cylinder so the old keys no longer turn it. We then cut new keys to match. It is usually the more economical route, and it works well when the hardware is sound and you're happy with how it looks and feels.
Replacement means taking the lock off and installing a new one. That makes sense when the hardware is worn, loose, damaged, or of a grade you don't trust, when you want a different finish or style, or when you want to step up to a higher-security or electronic lock.
Here is the short version we give people on the phone:
- Rekey when the lock works smoothly, looks fine, and you simply want old keys to stop working.
- Replace when the lock sticks, wobbles, is visibly worn, doesn't match your other hardware, or you want better security or a smart lock.
- Do a mix when it makes sense: for example, rekey the solid back-door deadbolt and replace a tired front-door handle set.
Why do Moorpark homeowners and renters change their locks?
Most calls we get about changing door locks fall into a handful of situations. None of them mean something is wrong with you or your home; they are just the moments when the number of people holding a key is no longer a number you know.
If you recognize your situation below, a lock change is the sensible next step, and you don't need to wait for a problem to justify it.
- You just bought a house and have no idea how many keys the previous owners, agents, contractors, and neighbors were handed.
- You're moving into a rental and the lock hasn't been touched since the last tenant moved out.
- A key was lost or stolen, and you don't know where it ended up.
- A roommate, partner, or relative moved out and still has keys.
- A former employee, house cleaner, or contractor once had access.
- The lock is simply worn out: the key sticks, the bolt drags, or the knob spins loosely.
- You want to change your door locks to a style that matches new fixtures, or to add a keypad or smart lock.

Call (213) 577-1366How do we change your locks, step by step?
We keep the process simple and we explain each decision as we go, because it's your door and your call. Here is how a typical lock change goes, whether you're in a tract home or a small rental.
- You call (213) 577-1366. Someone answers at any hour, any day. Tell us what happened, how many exterior doors you have, and whether anything is stuck, loose, or damaged.
- We help you sort out rekey versus replace over the phone, based on what you describe. If it's unclear, we'll say so and settle it when we see the door.
- A mobile technician comes to your address with tools, pins, and common hardware on the van.
- We look at each lock and the door itself: the condition of the cylinder, how the bolt lines up with the strike plate, and whether the door or frame has shifted.
- We explain what we recommend and what drives the cost, then do the work once you've agreed.
- We test every lock with the new keys, confirm the old keys no longer operate, and check that the door closes and latches without fighting you.
- We hand over the keys and show you anything worth knowing, such as how a keyed-alike setup works, or which key opens which door.
What affects the cost of changing locks in Moorpark?
We don't quote numbers on a web page, because the honest answer depends on your doors. What we can do is tell you exactly what moves the cost up or down, so nothing about the quote surprises you.
In general, rekeying existing hardware is the lighter-cost option, and replacement costs more because you're buying new hardware as well as paying for labor. But there are exceptions: a badly worn lock that can't hold a rekey reliably is a poor place to spend money.
- How many locks: a single front door is a different job from every exterior door, a garage entry, and a side gate.
- Rekey or replace: new hardware adds the cost of the hardware itself.
- Hardware grade and finish: basic, mid-range, and high-security locks differ a great deal, and so do matte, brushed, and specialty finishes.
- Type of lock: a plain deadbolt, a knob, a lever, a handle set, and a smart lock all involve different parts and setup time.
- Keyed alike or not: having every lock open with one key is convenient, and it may change the work involved.
- Door condition: if the door has shifted, the bore is damaged, or the latch no longer lines up, that has to be dealt with for the new lock to work properly.
- Extra keys: additional copies or restricted keys that can't be copied at a hardware store.
- Time and distance: night, weekend, and holiday calls, and travel to your address, can affect the total. Moorpark is roughly 45 miles from our Westwood storefront, and we'll be upfront about how that plays into your job.

Call (213) 577-1366Changing locks after buying a house: what new homeowners should do
If you're searching for a locksmith for a new house, the most useful thing to know is this: do the lock change before you sleep there the first night, or as close to it as you can manage. Keys from the sale, the listing, the inspection, and any earlier repair work are all unaccounted for until you change the locks.
Most new owners are best served by rekeying every exterior lock to one fresh key set, then deciding separately whether any individual lock deserves replacement. If you want to move to electronic entry at the same time, look at our smart lock installation service.
- Exterior doors: front, back, side, and any door from the garage into the house.
- Sliding doors: make sure the latch and any secondary lock or bar actually work.
- Garage: ask whether remotes and keypad codes were reset, and treat the previous owner's as still active until you change them.
- Mailbox: confirm you hold a key and that no one else does.
- Deadbolts: check that every entry door has one, and that it throws fully into the frame. If one is missing, a deadbolt installation is the fix.
- Spare keys: decide who really needs one, and keep that list short.
What changes locks in Moorpark homes specifically?
Moorpark is largely a master-planned suburb, and that shapes the lock-change jobs we see. The 1980s and 1990s single-family tracts in Mountain Meadows and Peach Hill are the classic setting for rekeying at move-in: a house that has changed hands once or twice has gone through a lot of keys, and a rekey across the exterior doors is the straightforward way to reset that. Most of those tracts, along with the 2000s homes in Moorpark Highlands, sit under HOAs, so if you're thinking of changing finish or style on visible hardware, check what your association expects before you pick something. Gate and garage locks in HOA communities are their own category, and we'll sort out what is yours to change and what belongs to the community.
Older parts of town can need more care. Near High Street in Old Town Moorpark, the homes are older and smaller, and cottage-style doors don't always accept modern hardware without adjustment, so we look at the door before promising a particular lock. Campus Park dates to the late 1960s and 1970s, and original-era hardware there may be well past its prime, which often tips the decision from rekey toward replace.
Heat matters too. Moorpark's inland valley setting brings hot, dry summers, cooler marine-influenced mornings, and seasonal Santa Ana winds. Those heat cycles can make doors and frames expand, especially on south- and west-facing entries in tract homes. If a new lock feels tight in the afternoon but fine in the morning, the door or frame may be the cause rather than the lock, and we'll check alignment so you're not blaming the wrong part.
Renters and landlords near Moorpark College deal with a different rhythm of turnover, and lock changes between tenants are routine there. If you're a property owner, see our locksmith for landlords page, and if you've ended up locked out of a rental, our apartment lockout service covers that. Everything above applies across the 93021 ZIP code, and we also work in the unincorporated Home Acres area next door.

What should you ask any locksmith before they change your locks?
Changing locks gives someone temporary access to your home, so it's reasonable to ask questions. 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 you're considering for that license number, and check it with the state before you let them start.
A few other questions are worth asking, whoever you call:
- Is the business located at a real address, or is it a call center that sends whoever is available?
- Will you explain what affects the cost before starting work?
- Will you show me that the old keys no longer work after the change?
- If I only need a rekey, will you tell me so, or push replacement?
Other services that often go with a lock change
A lock change rarely happens in isolation. Once the locks are new, most people want a few extra keys cut, and our key duplication service covers that, including keys that need to match a freshly rekeyed set. If your schedule is tight or you can't leave the house, our mobile locksmith service means the work happens at your door rather than at a counter.
If you're working through a bigger move, tell us about everything at once, including the gate, the garage entry, and any mailbox lock. It's easier for us to plan one visit than three, and it keeps your keys consistent from the first day.
Frequently asked questions
Is it better to rekey or replace my locks in Moorpark?
It depends on the hardware. If your locks work smoothly and look fine, rekeying is usually the more economical route and does the job of cancelling old keys. If they're worn, damaged, loose, or you want better security or a different style, replacement is the better choice. Call (213) 577-1366 and describe your doors, and we'll tell you honestly which fits.
Should I change the locks right after buying a house?
Yes, and the sooner the better. You don't know how many keys went to previous owners, agents, contractors, or neighbors. Most new homeowners rekey all the exterior locks to one new key set, then replace anything that's worn or doesn't meet their security needs.
Can you change locks at night or on a weekend?
Yes. Our phones are answered 24 hours a day, 7 days a week, year-round. Night, weekend, and holiday calls can affect the cost, and we'll explain how before we begin work.
Do I need to be home while you change the locks?
Someone over 18 who can confirm they're authorized to change the locks should be present, at least at the start and the end. We need access to each door, and we'll want to show you the new keys and test them with you before we leave.
Can all my doors work with one key?
In most cases, yes. We can rekey or set up the exterior locks so a single key opens them all, which is called keyed alike. We'll tell you if any particular lock can't be matched, and you can leave a door on its own key if you prefer.
Will changing the locks work with my HOA rules?
Many Moorpark neighborhoods, including Moorpark Highlands, are under HOAs. Rekeying doesn't alter how a lock looks, so it rarely raises questions. If you're swapping visible hardware, check with your association about finish and style first, and we can work around what they allow.
I rent near Moorpark College. Can I change my own locks?
Check your lease and talk to your landlord first. Changing locks without permission can create problems, and landlords often need to keep access. If you're a property owner, we can handle turnover rekeys. If you're locked out, that's a separate service we also cover.
Can you install a smart lock when you change my locks?
Yes. We can replace a standard deadbolt with a keypad or smart lock, but it depends on the door and what you want it to do. We'll look at the door and talk through how you want to enter before recommending anything.
How do I know the old keys no longer work?
We test it with you. After the work, we try the new key and show that the old key doesn't turn the lock, so you don't have to take our word for it.
