What does key duplication involve for a Stevenson Ranch home or business?
Key duplication is simple in concept: a new key is cut to match an existing one so more than one person can open the same lock. In practice, the quality of the copy decides whether it slides in smoothly for years or starts sticking within a few weeks. We cut house keys, duplicate deadbolt keys, copy apartment and office keys, make mailbox keys, and handle many high-security and restricted keys, either at our Westwood storefront or from a mobile van.
Stevenson Ranch is mostly single-family tract homes built in the 1990s and 2000s, with builder-installed hardware that is now decades old in many houses. A typical household has a front door, a deadbolt, a garage entry, maybe a side gate, and a mailbox, and each of those can take a different key. Getting a good spare for every one of them, in the right hands, is what most local key requests come down to.
Why do some copied keys stop working?
A key copy is only as good as the key it was cut from. Every duplicate carries tiny differences from its source, and when you copy a copy, those differences stack up. After a few generations the cuts can be shallow or off by a hair, and the key drags across the pin tumblers, sticks halfway, or turns only if you jiggle it. People then blame the lock, when the lock is usually fine.
Wear works the same way. A key carried for years on a ring loses metal along its ridges, and a copy of a worn key is a worn shape in fresh brass. Whenever we can, we prefer to cut from the original, or from the most accurate key in the household. If every key you own is tired, tell us. In some cases we can work from the lock itself instead of from a bad pattern.
Stevenson Ranch adds a local factor. Summers in the Santa Clarita Valley are hot and dry, and canyon winds funnel through Pico and Towsley canyons. Heat can make doors and frames expand slightly, and dust works its way into exterior locks. A key that feels stiff in August may be a dirty lock or a swollen door rather than a bad copy, and it is worth sorting that out before cutting five more keys from the same suspect original.
How do we duplicate a key, step by step?
The process is not complicated, but the details are where accuracy comes from. Here is how we run a typical job, whether it happens at the counter in Westwood or at your door.
- Identify the key: brand, keyway, and whether it is a standard key, a high-security design, or one stamped as restricted.
- Check its condition. If it is worn, bent, or cracked, we say so and suggest the best source to cut from.
- Select the correct blank, matching the keyway, length, and the way the key seats in the lock (shoulder or tip stop).
- Cut the copy on the machine, then remove burrs so the key does not catch or shed metal shavings inside your lock.
- Test it. When we are on site, we try the new key in your actual lock and deadbolt rather than trusting the machine alone.
- Hand over the keys, mark which is which if you have several similar ones, and talk through how many spares make sense for the household or the office.

Call (213) 577-1366Which keys can we copy, and which need extra steps?
Most keys are straightforward, but not all of them. Here is an honest breakdown of what we handle and where there are conditions.
- House and deadbolt keys: the most common request. Many homes use a different key for the knob and the deadbolt, so duplicate deadbolt key requests are often separate from the door key. Tell us how many locks the key family covers so no one is left without access.
- Apartment keys: we can copy apartment keys in most cases. If your lease or building rules say copies need management approval, check first. We may ask for confirmation before cutting a key that is stamped against duplication.
- Office and commercial keys: these are often tied to a larger system. Copies of a master or change key from a master key system usually require authorization from whoever controls the system. For general business work beyond keys, see our commercial locksmith service.
- Mailbox keys: small keys with their own blanks. A private mailbox lock can usually be copied, or replaced through mailbox lock replacement if the lock itself is failing. Boxes controlled by the Postal Service are handled by the Postal Service, and we will tell you if that is your situation.
- High-security keys: sidebar, dimple, and other protected designs need the correct blank and the right machine. Some can be cut with proper authorization. Learn more about those locks on our high-security locks page.
- Restricted keys: the manufacturer controls the blanks, and a copy needs the registered owner or a valid authorization card. In some cases the key can only be ordered from the manufacturer or a dealer. If that is true for yours, we tell you plainly and explain the route, which can take longer than an ordinary cut.
- Car keys with chips: a chip key needs programming as well as cutting. Whether we can do your vehicle depends on make, model, and year, and some are dealer-only. We confirm by VIN and in person rather than guess. Our transponder key programming page covers that side.
What affects the cost of key duplication?
We do not publish prices on a web page, because the honest answer depends on the key in your hand. Here is what moves the cost up or down, so there are no surprises when you call.
Quantity matters, but not as much as type. A standard house key is the lighter-cost end of the range. Costs rise as the key becomes more specialized, when a blank must be ordered, or when authorization has to be checked.
- Key type: a standard brass key versus a high-security, restricted, or chip-equipped key.
- Blank availability: common blanks are on the van and at the storefront; specialty blanks may need to be ordered.
- Condition of the original: a badly worn key can mean extra work to get an accurate copy.
- Quantity: cutting several keys in one visit is usually the more economical route than several separate trips.
- Location: bringing keys to our storefront is different from a mobile visit. Stevenson Ranch is about 32 miles from our Westwood base, so a van trip for one plain key is rarely the efficient choice.
- Time of day: the phone is answered around the clock, and after-hours visits are priced differently from daytime work.

Call (213) 577-1366Key duplication around Stevenson Ranch: Southern Oaks, The Palisades, Treana, and 91381
Stevenson Ranch, ZIP code 91381, is made up of several dozen named subdivisions on the west side of I-5, from Treana and Diamond Head to Bellagio, Toscana, and Marblehead. Most are single-family tract homes with builder-installed door hardware from the 1990s through the 2010s. That has a practical effect on keys: neighbors in the same tract often share keyways, so a key stamped with a common brand and profile is usually a straightforward cut. The harder jobs tend to be the older, much-copied keys.
One scenario we see in Stevenson Ranch is the home sale. In Southern Oaks and The Palisades, a house changes hands and the new owner has a set of keys, but no idea how many copies the previous owners, agents, or contractors made. The sensible order is to rekey the locks first, then cut your spare house keys from the new key. Doing it the other way around means paying for copies that stop working the moment the locks change.
Hillside homes backing open space near Richard Rioux Memorial Park often have more than one key to carry: garage, side gate, and front door. Gated and semi-custom enclaves such as Southern Oaks, south of Pico Canyon Road, can add further keys for gates or common areas. If your tract has HOA rules about exterior hardware, copying a key does not touch them, but replacing or changing exterior hardware might, so check before switching locks.
On the commercial side, shops at Valencia Marketplace on The Old Road need office and storefront keys for staff, and each employee set becomes a record to keep track of. If you run a business there, we can cut the keys and help you decide who should hold which one. When you cannot get to Westwood, our mobile locksmith service lets us bring blanks and a cutting setup to you. Call first so we send the right blanks.
Why have Wilshire Lock & Key cut your keys?
We have been in business since 1987, with a storefront at 10740 Wilshire Blvd in Westwood and mobile vans that serve 140 cities across Los Angeles and Ventura counties, Stevenson Ranch included. It is one company. When you call (213) 577-1366, you are not routed through a dispatch middleman who sends whoever is free; the phone is answered 24 hours a day, 7 days a week, year-round.
David, the owner and lead technician, oversees how the work is done. That matters with keys, because a bad copy looks fine until the day you need it. We would rather tell you your original is too worn to copy well than hand you a key that fails.
One more point, whichever locksmith you choose: California requires locksmith companies to hold a BSIS LCO license. Ask for it before any work starts. A reputable company will not mind the question.
Locked out or need a locksmith now?
We answer around the clock, every day of the year.
Call (213) 577-1366When is a copy not the right fix?
Sometimes people ask for duplicates when something else is going on. If you do not know who has copies, rekeying is the better answer. If you are locked out right now, a house lockout call is the first step, and we can cut spares once you are inside. If a key has snapped in the lock, stop turning it, because force makes extraction harder.
A copy is also not a cure for a lock that is failing. A key that works in some locks but not others, or a lock that has grown stiff, usually points to wear or dust rather than a bad key. We will check the lock before cutting more keys, so you do not end up with several new keys that all fight the same problem.
Frequently asked questions
Can you copy a key that says 'Do Not Duplicate'?
That stamp is not a lock on the key itself, but it usually means someone, such as a property manager or a system owner, wants copies controlled. We may ask for confirmation that you are authorized. If the key belongs to a restricted system, we will explain the proper route.
How many spare house keys should I have?
Enough that no single lost key leaves you stuck, but not so many that you lose track of them. For most households, one spare held by a trusted person plus one set for each adult is a sensible starting point. Tell us how many locks you have and we will help.
Can you come to my Stevenson Ranch home to cut keys?
Yes, our mobile vans serve Stevenson Ranch. Because we are based in Westwood, about 32 miles away, it helps to call (213) 577-1366 first so we bring the right blanks. Bundling several keys into one visit is usually the more economical route.
Can you duplicate a high-security or restricted key?
Often yes, but not always. Some need specific blanks or machines, and restricted keys require authorization from the registered owner. Some can only be ordered from the manufacturer or a dealer. We tell you which situation applies before we start.
What is the difference between a quick kiosk copy and a locksmith copy?
Accuracy and testing. We identify the exact blank, cut carefully, remove burrs, and try the key in the real lock when we are on site. We can also tell you when your original is too worn to copy well, which a machine cannot.
Do I need ID to get a key copied?
For ordinary house keys, usually not. For restricted systems, master keys, and some high-security keys, we may ask for ID, an authorization card, or confirmation from the property or system owner. This protects you and the people who rely on that lock.
Can you copy my car key?
It depends. Many modern car keys have a chip that must be programmed, and some vehicles are dealer-only. We confirm by VIN and in person instead of guessing from a make and model. For a simple metal-only key, cutting is usually straightforward.
Why does my new copy stick or not turn?
The copy may have been cut from a worn key, or the lock may be dirty or affected by a swollen door in summer heat. Bring both the copy and the original and we will check which one is at fault before cutting anything else.
Can you make a mailbox key if I have lost mine?
For a private mailbox lock, usually yes, either by cutting a key or replacing the lock if needed. For a box controlled by the Postal Service, that agency handles the keys, and we will tell you straight away if that is your case.
