What does key duplication involve for an Arcadia home or office?
Key duplication sounds simple: put a key in a machine, get a second key out. In practice the result depends on the blank, the calibration of the machine, the condition of the original, and whether the key is one that should be copied at a hardware-store counter at all. In Arcadia we handle the whole range: house key copies, a spare house key for every family member, apartment key copies, office key duplication, mailbox keys and the duplicate deadbolt key that always seems to go missing first. All of it comes from one company that has been cutting keys in Los Angeles since 1987.
You can reach us at (213) 577-1366 at any hour. Most duplication is not an emergency, so plenty of people call during the day. We answer around the clock anyway, because a call that starts as 'I need a spare' sometimes turns into 'I just locked myself out and my only key is inside.'
Why does a duplicate key sometimes fail to work?
A copy that goes into the lock but will not turn is the most common complaint we hear about key cutting. It is almost never bad luck. It usually traces back to one of a handful of causes, and knowing them helps you judge any key cutting service, ours included.
The other thing worth knowing is the 'copy of a copy' problem. Every generation of copy carries a little of the previous one's error, and a key worn smooth by years of use reproduces that wear faithfully. If your only key is a third-generation copy from a kiosk, the next copy may be the one that finally binds. Where the lock allows it, we would rather work from a cleaner original, or tell you honestly that the lock is the better thing to address.
- The wrong blank: a key that looks nearly identical but belongs to a different keyway or brand.
- A worn original: the cuts are already rounded, so the copy inherits the error.
- An uncalibrated machine: a small offset in the cutting depth is enough to keep the pins from lining up.
- Burrs left on the key: tiny metal edges that catch in the cylinder and make the key feel gritty.
- A lock that has its own problem: a worn cylinder or a misaligned strike plate can make a perfectly cut key feel wrong.
How do we duplicate a key, step by step?
Whether the job happens at our storefront at 10740 Wilshire Blvd or at your door, the sequence is the same. We do not rush it, because the checking at the end is where most of the quality comes from.
- Look at the key and ask what it opens: front door, deadbolt, side gate, office suite, mailbox or something else. The answer changes how we treat it.
- Identify the keyway and check for restriction markings or signs that the key belongs to a controlled system.
- Choose the correct blank for that brand and keyway, not a close substitute that merely fits.
- Cut the copy on a calibrated machine and remove the burrs so it slides cleanly.
- Test the copy in the lock it is meant for, and test your original too, so we know whether the lock or the key is the weak point.
- Adjust the cut if needed, then hand back the original and the copies. If the original is badly worn, we will say so plainly.

Call (213) 577-1366Which keys can be copied, and which cannot be copied freely?
Not every key is a walk-up job. Here is how the common categories break down in our work.
A stamp reading 'Do Not Duplicate' deserves a word of its own. On an ordinary key the stamp is a request, not a lock, and it does not by itself stop a machine. What does control copying is a restricted keyway, where the manufacturer limits who can order blanks and requires proof of authorization. We follow that process where it exists. If a key is part of a system someone else controls, we will ask who that is rather than guess.
- House and duplicate deadbolt keys: the most common request. Entry-lever and deadbolt keys are often different, so bring every key you want covered.
- Apartment and condo keys: these frequently belong to a building system, and the property manager or landlord may need to approve a copy. Landlords who need many keys managed can look at our locksmith for landlords service.
- Office and commercial keys: if your suite runs on a keyed hierarchy, copies may need sign-off from whoever controls it. Larger setups are better handled through a master key system.
- Mailbox keys: small keys with their own blanks. If the key is lost and no original remains, the real job is usually replacing the lock, which is covered under mailbox lock replacement.
- High-security and restricted keys: patented keyways need authorization, and some cannot be cut on a standard machine. We confirm what applies to your lock before promising anything, and our high-security locks page explains the hardware behind it.
- Car keys with chips: this is a different category from a house key. Whether a copy will start the car depends on the vehicle, so we confirm by VIN or in person, and some cases are dealer-only. We say so when that is the situation. See car key replacement for how that works.
What affects the cost of key duplication in Arcadia?
We do not quote numbers on a web page, because the honest answer depends on the key in your hand. What we can do is tell you exactly what moves the cost up or down, so nothing surprises you. Standard house keys are usually the more economical route. Anything that needs special blanks, authorization or a trip to you costs more than a simple counter job, and we will tell you which applies before we cut.
- Key type: a common single-sided house key is a different job from a high-security or restricted key.
- Blank availability: some blanks are stocked everywhere, others have to be sourced.
- Quantity: cutting several copies at once is a different job from cutting one.
- Authorization: restricted systems need paperwork or proof, which takes extra handling.
- Location: a copy made at our Westwood storefront involves no travel, while mobile key duplication means a van coming to you.
- Time of day: after-hours calls are handled differently from daytime visits.
- Condition of the original: a worn key may need extra care, or the lock may need attention first.

Call (213) 577-1366What does key duplication look like in Arcadia's neighborhoods?
Arcadia is about 27 miles from our Westwood base, and our mobile vans cover both ZIP codes, 91006 and 91007. The way people here need keys follows the housing, so here is what we actually see in the way homes and buildings are laid out.
In Santa Anita Oaks and the Upper Rancho, we do a lot of work around high-security deadbolt upgrades. Larger homes, many of them rebuilt from the 1990s onward, tend to have several entry doors, and an upgrade is only useful if the new keys are copied correctly and tracked. A high-security key is the one you do not want to lose, and that is exactly why a family should decide at the start how many authorized copies exist and who holds them.
The Arcadia Highlands add a different wrinkle. Hillside homes there often have gates, long driveways and multiple side entries, so one house can quietly need a lot of keys: the front door, the deadbolt, a side door, and a gate lock. Spare sets for those homes should be labeled, because five similar-looking keys get confusing fast. If the gate lock itself is the problem, see gate lock repair.
The older ranch homes in Lower Rancho and Santa Anita Village are where we most often meet keys that have been copied for decades. Worn keys from the 1930s-1950s era of housing are common. If a key is smooth and tired, we will cut the best copy we can, but we will also tell you if the lock has worn alongside it.
Climate matters too. Arcadia sits in the foothills below the San Gabriel Mountains, with hot summers and occasional Santa Ana wind events. South- and west-facing doors on hillside homes take heavy sun, which can warp door slabs over time. A warped door makes a deadbolt bind, and people often blame the key. Before cutting a new copy for a door that sticks only in summer, it is worth checking the door, not just the key.
Downtown Arcadia near Huntington Drive and First Avenue has condos and townhomes, and the same goes along Duarte Road. A condo key copy there usually involves the building: someone manages the lobby or garage fob, and it may not be ours to cut. For a lockout rather than a copy, see apartment lockout.
Why call Wilshire Lock & Key for spare keys?
We are not the only locksmith that can cut a key, so here is what we think actually distinguishes us, with nothing inflated.
One more thing, and it applies to any locksmith you hire. California requires locksmith companies to hold a BSIS LCO license, and you are entitled to ask any locksmith for it, including us. It is a reasonable question and a good habit.
- We have been in business since 1987, and key cutting is among the oldest parts of the trade.
- We operate a real storefront at 10740 Wilshire Blvd in Westwood alongside mobile service vans, so the work can happen in the shop or come to you.
- You deal with one company. There is no call center passing your job to a dispatch middleman you never meet.
- David, the owner and lead technician, oversees the work.
- Our phone is answered 24 hours a day, 7 days a week, year-round at (213) 577-1366.

Call (213) 577-1366Can mobile key duplication come to my Arcadia home or business?
Yes, for many jobs. Our mobile locksmith service is useful when you cannot leave a business unattended, when several doors on a property need copies, or when the lock needs to be inspected where it sits. Restaurants along the Baldwin Avenue dining corridor and retail stores around The Shops at Santa Anita are the kind of businesses where closing to run an errand costs more than a visit. We would rather come to the front door once and check every key in place.
Some keys still have to come back to the storefront. Certain high-security blanks and restricted keys fall into this group. We will tell you at the start of the call which kind of job yours is, so you are not left waiting on a van that cannot finish the work.
When is duplicating a key not the right fix?
Sometimes the right advice is not to copy the key. If you have lost a key and do not know who found it, or a former roommate, contractor or tenant still holds a copy, adding more keys makes the problem larger. In that case lock rekeying changes the lock so old keys stop working, and then new copies are cut for the new setup.
Call (213) 577-1366 and describe what you have in hand. We will tell you whether a quick copy is the right move, or whether the lock is asking for something different.
Frequently asked questions
Can you copy a key stamped 'Do Not Duplicate' in Arcadia?
Often yes, because on an ordinary key that stamp is a request rather than a technical block. But if the key belongs to a restricted system, the manufacturer controls blanks and authorization is required. We check which one you have and ask for proof where the system demands it.
Do I bring the key to you, or do you come to me?
Either. You can visit our storefront at 10740 Wilshire Blvd in Westwood, or we can send a mobile van to your Arcadia address. Some keys can be cut at the door, while others have to come back to the shop, and we tell you which applies when you call.
How many spare keys should a house have?
Enough that each person who needs access has one, plus one held somewhere safe that is not under a doormat. More copies mean more chances for one to go missing, so label each set and keep track of who has which.
Can you duplicate a high-security key?
Sometimes. High-security and restricted keys use controlled blanks and often require authorization from the owner of record. We confirm what your lock needs before cutting, and we will tell you plainly if a copy has to go through the manufacturer or cannot be made.
Can I get a copy of my apartment or condo key?
Usually, but the building may have a say. Many apartment and condo keys belong to a system managed by the landlord or HOA, and a copy may need their approval. If the building does not control the key, we can often cut it directly.
Do you make mailbox keys?
Yes, when you still have an original to copy from. Mailbox keys use their own small blanks. If every key is lost, the fix is generally replacing the lock rather than copying, and mailboxes owned by the property or postal system may need permission.
Can you copy a car key with a chip in it?
A chip key is not a simple cut-and-go job. Whether a copy will start the car depends on the vehicle, so we confirm by VIN or in person, and some cars are dealer-only. We tell you honestly which case yours is before doing any work.
Why does my new copy stick or refuse to turn?
The usual causes are a worn original, the wrong blank, burrs left on the cut, or a lock that has worn itself. Bring the copy and the original together and we can tell whether the key needs adjustment or the lock needs attention.
How do I know a locksmith in Arcadia is legitimate?
Ask for their BSIS LCO license. California requires locksmith companies to hold one, and a legitimate company will not mind the question. Also look for a real address and a company that answers its own phone.
