What does key duplication involve, and when do Palmdale customers need it?
Key duplication is cutting a new key to match an existing one, so more than one person can open the same lock. On paper it is one of the simplest jobs a locksmith does. In practice, the quality of the cut decides whether you get a spare that slides in and turns smoothly, or one that sticks, jiggles, and slowly chews up the pins inside your lock. A key is a precision part, and a difference you can barely see is enough to change how it behaves.
People in Palmdale call us for duplicate keys for ordinary reasons. A family moves into a house and has one key for four adults. A property manager needs sets for a new tenant. An office has one key and a growing team. A mailbox key went missing, or a deadbolt key was never copied because only two were handed over. None of these is an emergency, which is exactly why a spare house key is worth sorting out now. Making an extra key on your own schedule is usually the more economical route compared with an urgent lockout call later.
This page is about copying keys: house, apartment, office, mailbox, deadbolt, and high-security keys. If what you really need is a different outcome, such as changing who can open a lock after a key went missing, that is a different job, and we point you to it below.
Which keys can Wilshire Lock & Key copy?
Most standard keys can be copied, meaning the common keys that fit house locks, deadbolts, and office doors. The harder questions come with unusual keyways, restricted blanks, and keys that have been copied and re-copied until the cuts have drifted from the original. Here is how we sort the common requests:
- House key copy and spare house key: front-door, back-door, and garage-entry keys, cut to match the key you already have.
- Duplicate deadbolt key: a deadbolt is often on a different keyway than the knob in the same door, so we match the blank to the specific lock instead of assuming.
- Apartment key copy: unit keys, plus the mailbox, laundry, or gate keys that tend to ride on the same ring. Many buildings have rules about who may copy keys, so we may ask for the manager's okay.
- Office key duplication and commercial key duplication: door, desk, file cabinet, and storefront keys, with attention to who is authorized to hold them.
- Mailbox key duplication: small keys that are usually specific to the box. If the lock can't be matched or the original is gone, replacing the lock is the better fix, and our mailbox lock replacement page explains it.
- High security key duplication and restricted key duplication: handled case by case, covered in its own section below.

Car keys are the one category we treat separately. A modern car key can contain a transponder chip or a remote function that a simple cut will not satisfy, and we do not guess from a description over the phone. We confirm what a given vehicle needs by VIN and in person. Some vehicles and key types may turn out to be dealer-only, and if yours is one of them we will tell you plainly instead of letting you pay for a key that won't start the car. Car keys come up again in the local section below.
How we handle a duplicate key, step by step
Here is how a duplicate key job goes, whether you bring the key to our Westwood storefront or we meet you in Palmdale.
- You tell us what the key opens: front door, deadbolt, office, mailbox, or something else, and how many copies you want. If you can describe the markings stamped on the key head, that helps us identify the type before anything gets cut.
- We identify the key and the correct blank. The blank has to match the keyway, which is the profile of the slot in the lock. Many blanks look alike and are not interchangeable.
- We inspect your original. If it is worn, bent, or a copy of a copy, we say so. Copying a worn key reproduces the wear, and sometimes the better route is working from a cleaner source key.
- We cut the copy and remove the burrs. Loose metal left on a fresh cut drags through the lock and wears it faster than a clean edge would.
- We test the new key. When the lock is available, we try the copy in it to confirm it turns smoothly rather than assuming. If the lock is not with us, we say so and ask you to test it as soon as you are back at the door.
- We tell you what we noticed. If the lock feels rough, gritty, or sticky, we mention it, because a good new key in a struggling lock is still a problem.
Why do some copies stick or fail, and what does the high desert have to do with it?
Most bad copies come from one of three things: the key was cut from a worn original, the wrong blank was used, or the burrs were never cleaned off. The simplest protection is to always copy from your original key, not from a copy. If the key on your ring is the third or fourth generation, find the oldest, best-condition key in the house and bring that.
Palmdale's climate adds its own wrinkles. The Antelope Valley has very hot summers, freezing winter nights, and strong, dusty winds. Big temperature swings cause seasonal door and frame movement, so a deadbolt that lines up perfectly in spring can bind a little on a cold morning, and people blame the key. Wind-blown grit also shortens the life of exposed exterior locks, and grit inside a keyway makes any key feel stiff.
Before deciding a new copy is bad, check the lock. If the copy works smoothly on the counter but drags in the door, the lock or the door alignment may be the real issue. If you use lubricant, a dry graphite or PTFE-type product is a safer choice than oily sprays, which hold dust. And if your key is cracked, bent, or already tough to turn, stop forcing it. A key that snaps in the lock turns a simple copy job into broken key extraction, which is a harder day than it needed to be.

Call (213) 577-1366Can high-security and restricted keys be duplicated?
Sometimes yes, sometimes only with authorization, and a few only through the manufacturer or a dealer. We cannot give you an honest answer without seeing the key or knowing the lock brand. High-security systems use restricted keyways and blanks that are deliberately hard to obtain, and many are tied to a card or a registered owner. That is the entire point of them.
A 'Do Not Duplicate' stamp is not proof that a key can't be copied, and it is not a magic wall either. We treat it as a signal to slow down. We ask who owns the key and who is authorized, and for restricted systems we ask for the paperwork or the owner's authorization. If we can't copy a key responsibly, we say so and tell you who can.
If you have a restricted system and lost the authorization card, tell us the lock brand when you call and we will explain what the process looks like. If you are thinking about upgrading from standard keys so unauthorized copies are harder to make, read about high-security locks in Palmdale.
How does office and commercial key duplication work?
Copying a key for a business is more about control than cutting. Every extra key is one more person who can open the door after hours. Before we copy a commercial key we want to know who is asking and whether they are authorized, and we would rather ask an awkward question than be the reason an unknown key exists.
The industrial and aerospace-adjacent buildings near U.S. Air Force Plant 42 are the sort of sites where a facilities manager usually wants a tight record of who holds which key. If your building has its own key policy, we follow it. A few habits make office keys easier to manage:
- Keep a simple log of who holds each key, and update it when staff change.
- Separate keys by area, such as front door, stockroom, and file cabinets, so one lost key doesn't open everything.
- Treat any key that opens multiple doors as a higher-stakes copy and limit who can request it.
- If keys keep multiplying and tracking them has become a chore, a master key system may serve you better than more copies.
What affects the cost of duplicate keys?
We don't post numbers on a web page because the honest answer depends on the key in your hand. These are the factors that move the cost up or down:
- Key type: a standard house key with a common blank is the lighter-cost kind of job. Specialized and high-security keys involve more.
- Blank availability: restricted or less common blanks are harder to source.
- Authorization: restricted keys can require paperwork or owner verification before they can be cut.
- Quantity: a handful of copies is a different job than a full set for a building.
- Condition of the original: a badly worn key can take extra work to copy accurately, or may call for a different approach.
- Where the work happens: coming to the shop is usually more economical than having a van come to you, since travel and time are part of the service.
- Time of day: after-hours calls can be priced differently than daytime ones.

Call (213) 577-1366Key duplication around Palmdale: homes, apartments, and mailboxes
East Palmdale holds the older 1950s to 1980s housing tied to the aerospace industry. Older homes often mean older hardware and keys that have been copied many times over the decades. If you live in one, bring the best original you can find so the new copy does not inherit years of drift.
West Palmdale grew rapidly from the late 1980s through the 2000s, with large stucco tract homes around Rancho Vista and the Antelope Valley Country Club Estates. Houses like these tend to have several exterior doors, such as the front, a garage entry, and a side or back door, and a spare house key for each adult adds up quickly. Anaverde, the newer master-planned community in the southwest hills, is a good place to make extra sets early, before the originals see much wear. If you moved into any of these homes and don't know how many copies previous occupants made, copying will not answer that question. Lock rekeying will.
Apartment and duplex stock concentrates along Palmdale Boulevard and the eastside avenues. For an apartment key copy, we may ask for the manager's permission, since many buildings control their keys. Property managers who need sets for turnovers can read about our locksmith services for landlords. We cover Palmdale's ZIP codes 93550, 93551, and 93552, and customers in nearby unincorporated areas like Sun Village or Desert View Highlands can call the same number so we can confirm service.
Car keys come up here too. Replacement car keys at the Palmdale Transportation Center park-and-ride are a scenario we know about, and anyone who parks there for a Metrolink commute knows how bad it is to lose the only key. A spare made before that happens is an easier conversation. Because chip and programming needs vary by vehicle, we confirm by VIN and in person, and our car key replacement page explains the details.
Palmdale is about 59 miles from our Westwood storefront at 10740 Wilshire Blvd, so for most Palmdale customers mobile key duplication is the practical route. Tell us the key type on the phone, and we will say plainly whether it can be done at your door or needs the shop.

Call (213) 577-1366Ask any locksmith for a license number
California requires locksmith companies to hold a BSIS LCO license, issued through the Bureau of Security and Investigative Services. Ask any locksmith for it before you hand over keys or open your door to them. It is a fair question, and a reputable company will not mind being asked.
When you are ready for a spare, call (213) 577-1366. Tell us which key it is and what it opens, and we will say honestly what can be done.
Frequently asked questions
Can you copy a key marked 'Do Not Duplicate'?
It depends on the key and the lock. That stamp is a signal, not a guarantee either way. We ask who owns the key and who is authorized, and for restricted systems we ask for the owner's authorization or paperwork. If we can't copy it responsibly, we say so and tell you who can.
How many spare house keys should I have?
Enough that no one gets locked out and no key is the only one. Many households keep one for each adult, plus one with a trusted person. Skip the fake rock and the doormat. If you aren't sure who already has copies of your keys, rekeying is the better fix.
Is it better to copy my original key or a copy?
Your original, every time. Each generation of copy carries small errors from the one before, so a copy of a copy of a copy can stick, jiggle, or wear the lock. Bring the oldest, cleanest key you have.
Can you duplicate a car key in Palmdale?
Sometimes, but cars are different from houses. Many keys have a transponder chip or remote that a simple cut doesn't cover. We confirm what your vehicle needs by VIN and in person, and some vehicles may be dealer-only. We will tell you plainly if yours is one of them.
I lost my only mailbox key. Can you make a copy?
Without a key, there is nothing to copy from, so replacing the lock is often the answer. If the box belongs to a building or complex, the property manager may need to be involved. Call us with the box type and we will explain the options.
Can you come to my home or office in Palmdale to copy keys?
Yes, our mobile vans serve Palmdale. Tell us the key type when you call, and we will say plainly whether the job can be done at your door or needs the Westwood shop. Specialized and restricted keys sometimes need the shop.
How much does key duplication cost in Palmdale?
It depends on the key type, blank availability, authorization needs, how many copies you want, the condition of your original, whether we come to you, and the time of day. A standard house key is the lighter-cost kind of job. Call (213) 577-1366 and describe your key.
What if my new copy sticks or won't turn?
Tell us, and bring both the new copy and the original. We will look at the key and the lock together. Sometimes the cut is the problem, and sometimes the lock is worn or full of desert grit, so a fresh key can't fix the real issue.
