What does key duplication involve, and why does a good copy matter?
On paper, copying a key is simple: a blank is cut to match the pattern of cuts on your original. In practice, the quality of the copy decides whether the key slides in smoothly or fights you every morning at the door. A copy that is a hair off will often work on a bad day and fail on a worse one, usually when your hands are full or the weather is turning.
Most of the trouble we see comes from copies of copies. A key gets duplicated, that duplicate gets duplicated, and each generation drifts a little further from the original cuts. By the third or fourth round the key may turn only if you jiggle it, and the jiggling wears the lock's pins along with the key. If you still have the original, or the first-generation copy, that is always the best thing to bring us.
We have been cutting keys since 1987, and the habits that matter have not changed. We start from a clean, undamaged key, match it to the right blank, cut it carefully, and test it in a lock before it leaves our hands. This page explains how that works, what can and cannot be copied, what changes the cost, and what is specific to Glendale homes and buildings.
How we copy a key, step by step
Whether you walk into our Westwood storefront at 10740 Wilshire Blvd or a technician meets you in Glendale with a mobile van, the process is the same.
- We look at the key you bring. We check for wear, bends, cracks, and whether it has been copied several times already.
- We identify the keyway and brand so we choose the correct blank. Many keys look alike but differ in width, groove profile, or shoulder length, and the wrong blank will never work reliably.
- We check whether the key is a standard, restricted, or high-security type. That decides whether we can cut it on the spot or need authorization first.
- We cut the new key to the pattern of the original, then remove the burrs left by cutting so the key does not scrape the inside of your lock.
- We test the copy in the actual lock whenever the lock is available. When you are at our counter and the lock is at home, we tell you plainly that the final test happens at your door.
- If the copy sticks or turns roughly, we recut or look at the lock itself. Sometimes the key was fine and the lock is the one that is worn or binding.
- We label or sort the keys with you, especially for multi-door properties, so you do not leave with a handful of lookalike keys and no idea which is which.

Call (213) 577-1366Which keys can we copy, and which need extra steps?
Most keys are straightforward. Some are not, and we would rather tell you that up front than cut something that will not work or that we should not be cutting.
Here is how the common types break down:
- House key copy and spare house key: standard residential keys for entry doors are the most common request and usually the quickest to cut.
- Duplicate deadbolt key: deadbolt keys are often a different keyway from the knob lock on the same door, so bring the key for each lock you want copied.
- Apartment key copy: fine for ordinary keyed apartment doors. Building-issued entry keys and fobs are another matter, and we cover that in the Glendale section below.
- Office key duplication and commercial key duplication: standard office and storefront keys are no problem. If your keys belong to a keyed-alike or master-key arrangement, bring the key and tell us who manages the system, and see our master key system work if you are planning to reorganize who can open what.
- Mailbox key duplication: mailbox keys are small and easy to cut but easy to mix up. If you have lost the only one, a copy is not possible and the answer is usually a mailbox lock replacement.
- High security key duplication and restricted key duplication: these keys are built so they cannot be freely copied. Cutting them typically requires proof of authorization, a registered card, or ordering through the manufacturer. Our high-security locks page explains how those systems work. We will tell you honestly if a key can only be obtained through the dealer or the lock's maker.
- Keys stamped 'Do Not Duplicate': the stamp is only a stamp, not a lock. Whether we cut it depends on the keyway and whether the system is restricted. We will not cut a key we have reason to think you are not entitled to copy.
- Car keys with a transponder chip: a plain metal cut is only part of the job on those. Chip and programming details vary by vehicle, and we confirm them by VIN or in person rather than guess. Our transponder key programming page covers that work.
What affects the cost of duplicate keys?
We do not quote prices on a web page, because the honest answer depends on the key in your hand. These are the things that move the cost up or down:
- Key type: a common brass house key is the lightest-cost job. Restricted and high-security keys cost more because the blanks are specialized and the authorization process takes time.
- Quantity: cutting several copies of the same key in one visit is usually the more economical route than coming back for them one at a time.
- Condition of the original: a worn or damaged original may need extra work, or may be better replaced by a fresh key cut from the lock itself.
- Where the work happens: a counter visit to our storefront is different from a mobile visit to your address, because the mobile visit includes the technician's travel.
- Time of day: urgent after-hours calls cost differently from daytime counter work.
- Whether you need other work: if the real issue is a worn lock, you may need repair or rekeying, and we will say so rather than sell you copies that will not fix it.

Call (213) 577-1366Can you come to me for mobile key duplication?
Yes. We run mobile service vans alongside our Westwood storefront, and Glendale is part of our service area at about 18 miles from our base. That distance is simply why we ask a few questions on the phone before we dispatch. We want to bring the right blanks for your key type and not make a second trip.
Mobile key duplication is most useful when the keys are hard to leave behind: a property manager who needs several doors handled at once, an office that cannot close for an hour, or someone who is housebound and cannot get to a counter. It is also the sensible choice when you want the copy tested in the lock on the spot. Read more on our mobile locksmith page.
For a single plain house key and no particular hurry, bringing the key to us is usually the more economical route. If you are not sure which fits your situation, call (213) 577-1366 and describe the key. We answer the phone around the clock, and we will give you a straight recommendation.
Why have Wilshire Lock & Key cut your keys?
We try to stay honest about what makes us different, and we would rather list a few real things than a pile of adjectives.
We have been in business since 1987, so we have cut keys for most of the lock brands and many of the odd, older ones you will find in homes that predate modern hardware. We have a storefront on Wilshire Boulevard and mobile vans, so you can bring a key to us or have us come to you. We are one company. When you call, you reach us, not a dispatch center that sells your call to whichever contractor picks it up. And David, our owner and lead technician, oversees the work.
One more thing worth knowing: California requires locksmith companies to hold a BSIS LCO license, and you should ask any locksmith for it before they work on your locks. That applies to key cutting too, since a key is only as trustworthy as the company that has your pattern and your address.
Key duplication in Glendale: what we see across the city
Glendale covers a lot of different housing, and what you need from a key copy changes with it. We serve the city's ZIP codes, from 91201 through 91208 and 91020, and the key issues differ from block to block.
In the 1920s Spanish and Tudor revival homes of Rossmoyne and Adams Hill, the keys themselves are often the problem. A house that has gone through decades of owners may have keys that have been copied again and again, with each generation a little blurrier than the last. If the front door key only works with persuasion, the fix may be a fresh cut from a clean original, or a decision to rekey the lock so every key is new. A new copy of a worn key just makes you carry a worn key twice. The dense apartment and condo core south of downtown is a different story: it sees ordinary daily wear, so keys that fail are mostly just old, and one clean replacement is often all it takes.
Up in Chevy Chase Canyon and Glenoaks Canyon, the mid-century hillside houses add gates, garages, and side doors, which means a single household can be carrying five or six keys. The Santa Ana winds and strong canyon sun dry out wood doors on hillside homes, and a door that has shifted can make a lock bind. That is worth knowing before you blame the key. If a fresh copy still sticks, bring it to us or ask about the door.
Near The Americana at Brand and along Brand Boulevard, the high-rise and podium condo buildings have controlled-access lobbies. Residents often ask for copies of a unit key, which is straightforward. The lobby key, fob, or access card is usually managed by the building, and we cannot treat that as ours to copy. Check with your property manager or HOA first. If you are locked out of one of these buildings, our apartment lockout service is the better page to read.
In Montrose and Sparr Heights, smaller 1920s to 1950s cottages mean ordinary house keys, and many of those homes still run original hardware. Further along, storefronts on Brand Boulevard and Honolulu Avenue in Montrose are a regular source of commercial key duplication. A shop owner who needs a spare for a new employee, or a landlord handing out keys to a new tenant, can bring the original in or ask us to come out. Landlords with several doors may find our locksmith for landlords page useful.

Call (213) 577-1366When a copy isn't the right answer
Sometimes the honest advice is not to cut another key. If a key has been lost and you do not know where it went, a copy of a surviving key does nothing about the missing one. In that case, rekeying the lock makes the old key stop working and gives you a clean set. If you or a family member has snapped a key off inside a lock, we need to remove the broken piece first, and our broken key extraction service handles that.
It is also worth saying that a copy cannot fix a lock that is failing. If the key goes in but will not turn, or a key you had cut elsewhere works only half the time, the lock may need attention. We would rather examine it than watch you pay for a fourth copy that does not solve anything.
When you are ready, call (213) 577-1366 at any hour. Tell us what kind of key it is, where the lock is, and whether you want to come to us or have us come to you. If the key is a restricted or high-security type, tell us that too, and we will explain what is needed before anyone cuts anything.
Frequently asked questions
Can you copy a house key while I wait?
Usually, yes. Standard residential keys are quick work at our Westwood storefront, and a mobile technician can often cut one at your address. Restricted or high-security keys may need authorization first, so call (213) 577-1366 and describe the key.
Do you offer mobile key duplication in Glendale?
Yes. Our mobile vans serve Glendale, and we answer the phone 24 hours a day. We ask what kind of key you have so the technician brings the right blanks.
Can you copy a key marked 'Do Not Duplicate'?
It depends. The stamp is not a security feature, and many stamped keys are standard keyways that can be cut. If the key belongs to a restricted system, we need proof of authorization, and we will not cut a key we think you are not entitled to copy.
Can you duplicate high-security or restricted keys?
Sometimes, but not freely. These systems are designed to limit copying, so the process typically requires an authorization card, proof of ownership, or an order through the manufacturer. We tell you honestly if a key can only come through the dealer or maker.
Can you copy my apartment or condo building's entry key or fob?
We can copy ordinary keys for your own unit. Lobby keys, fobs, and access cards are usually controlled by the building, so we ask you to check with your property manager or HOA first. In controlled-access buildings, we want to be sure the copy is authorized.
How do I get a mailbox key copied in Glendale?
If you have the original, bring it to us and we can cut a copy. If the only key is lost, copying is not an option and the lock typically needs to be replaced. We can walk you through which applies.
Is it better to copy a key or rekey the lock?
A copy is the right choice when you simply want another working key and all existing keys are accounted for. Rekeying is the better choice when a key is lost, stolen, or in the hands of someone who should no longer have access.
Why does my new copy stick or turn roughly?
Often because the copy was made from a worn copy, or the blank was slightly wrong. Sometimes the lock itself is worn, or a dry hillside wood door has shifted and is binding the bolt. Bring the key and the details, and we will tell you where the problem sits.
