Why does the quality of a duplicate key matter?
Copying a key looks like the simplest job in the trade, and when it goes well it is. But a duplicate is only as good as the key it was cut from and the care taken at the machine. A copy that is off by a few thousandths of an inch on a single cut can feel fine for a week and then start to stick, drag across the pins, or refuse to throw a deadbolt all the way. Worse, a rough copy wears the lock's internal parts faster, so a key problem slowly turns into a lock problem.
Most bad copies come from the same chain of events. A worn original gets copied, that copy gets copied, and each generation drifts a little further from the cuts the lock was built for. By the third or fourth generation the key only half fits. The fix is simple: copy from the best key you have, ideally the original or one that was cut properly in the first place, and test the result before anyone walks away.
This page covers duplicate keys for Inglewood homes, apartments, offices, and mailboxes. It explains what we can copy, what we can't, what moves the cost, and how mobile key duplication works when you would rather not make the trip. If your real problem is a lockout, a broken key in the lock, or a lost car key, those are different jobs, and we point you to the right pages below.
What kinds of keys can we copy in Inglewood?
Most keys people bring us are ordinary pin-tumbler keys for doors, and those are the bread and butter of a key cutting service. Here is what typically comes across the counter or gets handled at your door:
- House key copy and spare house key requests for front doors, back doors, side gates, and garage entries.
- Duplicate deadbolt key jobs, which matter because many homes have the deadbolt keyed separately from the knob or handle set.
- Apartment key copy for unit doors, building entries, storage rooms, and similar, as long as the key isn't restricted (more on that below).
- Office key duplication and commercial key duplication for suite doors, storefronts, desks, and file cabinets.
- Mailbox key duplication for private and building mailboxes. If the box belongs to the postal service or to building management, they may control the keys, and we'll tell you honestly what is possible.
- Padlock, cabinet, and utility keys that have a clear keyway and a readable blank.
- High security key duplication and restricted key duplication, which follow their own rules and are covered in their own section.

Call (213) 577-1366How does a key duplication job work, step by step?
Here is how we handle a typical request, whether it happens at the storefront on Wilshire Boulevard or at your door.
- Look at the key you have. We check the keyway, any brand stamp, and how worn the key is. A fresh original cuts a better copy than a tired one.
- Choose the source. If your key is the original or close to it, we copy it. If it is badly worn, we may cut from the lock's code or work from the lock itself so the new key is not a copy of a copy.
- Match the blank. Blanks look alike but are not interchangeable. A blank with the wrong keyway may slide in but never turn, so we match the blank to the lock, not just to the shape.
- Cut and deburr. The key is cut on the machine, then the burrs are cleaned off. Leftover burrs are a quiet cause of rough, gritty keys that wear locks.
- Test it. Where we are at the lock, we try the new key in the real lock and the real deadbolt. At the shop, we compare it against the original and check the cuts.
- Hand it back with plain advice. If your original is worn out, we say so, so you don't keep copying a failing key.
What about restricted and high security keys?
Some keys can't simply be cut on request, and a locksmith who says otherwise is either guessing or cutting corners. Restricted keyways are protected by the manufacturer's rules, often with patents behind them, and duplicates are normally made only with authorization from whoever controls the key system: a card, a registered account, or approval from the property owner or manager. If you bring us a restricted key, we will ask who is authorized and explain what we need before cutting anything.
A stamp reading 'Do Not Duplicate' is a different matter. That stamp is a request, not a lock on the key, and plenty of machines will still cut it. We treat it as a signal to check who controls the system, especially in an office, a rental building, or anywhere a master key system sits above the individual door. You can read more about how those systems work on our master key system page.
High security keys are their own category. Sidebar, dimple, and laser-cut keys need specific equipment, and some are available only from the manufacturer or a dealer. We don't promise to copy every one. We confirm by looking at the key in person, and if a particular key is dealer-only, we tell you plainly instead of letting you wait on something we can't deliver. If you are considering upgrading to a lock whose keys are harder to copy, see our high security locks page.

Call (213) 577-1366What affects the cost of key duplication?
We don't quote numbers on a web page, because the same request can be a quick job or a longer one depending on the key. What actually moves the cost:
The type of key matters first. A standard brass house key is the simple end of the range, while high security and restricted keys involve special blanks, special machines, and sometimes authorization paperwork. The availability of the blank matters too: common blanks are easy to find, unusual ones may need to be sourced.
The condition of the original is next. A clean original copies quickly. A worn or bent one may need to be cut by code or matched at the lock, which takes more time and care. The number of keys changes the picture as well, though a batch for a household or office is usually more economical per key than ordering one at a time.
Then there is where the job happens. Coming to the storefront is the lighter-cost route for a simple key. A mobile visit adds travel, and Inglewood sits about 11 miles from our Westwood base, and the time of day can matter for late-night requests. Describe the key when you call (213) 577-1366 and we'll tell you what applies to your situation before anything is cut.
Can we come to you for mobile key duplication?
Yes. Alongside the Westwood storefront at 10740 Wilshire Blvd, we run mobile service vans, so key duplication doesn't always require you to leave your building. Mobile key duplication makes sense in a few situations: an office or small business that needs several keys cut without shutting down for a trip, a household where nobody can easily get away, or a lock that is stiff enough that we want to test the new key right at the door.
Testing at the lock is the real advantage. A key can look perfect on the bench and still bind in a worn deadbolt. When we are standing at your door, we find that out immediately and fix it instead of sending you home with a copy that sticks.
The shop is usually the better route for a simple, standard key you can easily carry in. We'll tell you which route fits when you call. Our mobile locksmith page explains how the vans work in general. The phone is answered around the clock, so a request for a spare at an odd hour is a conversation with a person, not a voicemail box.

Call (213) 577-1366What does key duplication look like around Inglewood?
Inglewood is largely a renter's city, and that shapes how spare keys get used. Along the Century Boulevard and La Brea corridors there is a large stock of apartments, where one lease often means several people who each need a working key. Copies get passed around, lent out, and lost, which is why an apartment key copy is one of the most common requests we expect here. If you rent, check your lease first, because some buildings limit copying of entry keys, and we may ask for a sign of authorization on restricted ones. When the question is whether the people holding old copies should still have access, the right tool is a rekey, not another duplicate.
The older homes tell a different story. In Fairview Heights and Morningside Park, the 1920s to 1940s Spanish bungalows have often been through decades of tenants and owners, and the keys that open them have been copied many times over. Security screen doors and window bars are also common on older homes and small apartment buildings in the denser parts of the city, and those typically have their own lock and their own key. If a duplicate deadbolt key works but the security door key is a mystery, bring both. On Morningside Park bungalows, a gate or security-door key that sticks is often a sign the copy is tired or the lock needs attention.
Downtown Inglewood has its own needs. Storefronts on Market Street run on office key duplication and commercial key duplication: keys for the front door, the back door, and the cabinets inside, held by an owner and a few staff. Near SoFi Stadium, the Hollywood Park development is adding newer condominium and apartment buildings, where many units run smart locks. Even then, a mechanical backup key is often the only physical key, and it is worth copying carefully; our smart lock installation page covers the electronic side.
We take key duplication requests from every part of Inglewood, including North Inglewood, Arbor Village, Lockhaven, Crenshaw-Imperial, and Inglewood Knolls, across ZIP codes 90301 through 90305. The climate is mild. Inglewood gets marine-layer mornings but little direct salt exposure, so the effect on door hardware is modest. When a key here is worn, the cause is almost always years of use, not corrosion.
When is a copy not the right answer?
A duplicate is a good answer when you know where every existing key is. It is the wrong answer in a few situations, and we would rather say so than cut another key that doesn't fix the real problem.
If you've just moved in and don't know who holds copies, a new key does nothing about the old ones, and lock rekeying is the right job: the lock is changed so old keys stop working, and you get new ones. If you've lost your only key, you need a different kind of service, because a duplicate requires something to copy from. If a key is breaking off in the lock, that is broken key extraction, not copying.
Property owners with several units sometimes ask for dozens of copies. That can work, but it is better planned through a key system than done as a pile of duplicates; our locksmith for landlords page explains the options. For cars, a duplicate is not the same thing as a cut metal key, since many vehicles use chips that need programming; we confirm by VIN or in person instead of guessing. Our car key replacement page covers that work separately.

Call (213) 577-1366Why call Wilshire Lock & Key for spare keys?
We have been in business since 1987, and we serve 140 cities across Los Angeles and Ventura counties. That means we have cut keys for many kinds of buildings and many ages of locks, and we know when a worn key needs more than a quick pass at the machine.
We are one company. The person who answers (213) 577-1366 is part of the same operation that cuts your key; there is no dispatch middleman passing your request to a stranger. David, the owner and lead technician, oversees the work. We have a real storefront and mobile vans, so you can walk in or have us come to you.
One more point of honesty: 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 goes for us as well.
Frequently asked questions
Can you copy a key marked 'Do Not Duplicate'?
That stamp is a request, not a legal barrier, but we treat it seriously. We ask who controls the key system, and if the key is restricted or part of a master key system, we need authorization from the owner or manager. If the key is simply stamped and not restricted, we'll explain our options before cutting.
How long does it take to duplicate a key?
A standard house key is a short job at the machine. High security, restricted, or worn keys take longer because of blank sourcing, authorization, or matching at the lock. We don't promise times we can't keep, so describe your key when you call (213) 577-1366.
Can you make a spare key at my Inglewood home or office?
Yes. Our mobile vans can handle many duplication jobs at your door, and testing the new key in the real lock is a real advantage. Some keys are better handled at the Westwood storefront, and we'll tell you which route fits when you call.
Do I need the original key, or can you copy a worn one?
A good original gives the best copy, but a worn key can often still be copied or used as a starting point. If it is badly worn, we may cut by code or match it at the lock instead of copying the copy, and we'll tell you if the original should be retired.
Can you duplicate a mailbox key?
Often yes, for private and many building mailboxes. If the box belongs to the postal service or building management, they may control the keys and we'll tell you what is possible rather than guess. Bring the key, or tell us the mailbox type, when you call.
Can I copy my apartment key if I rent?
Usually for a standard unit key, yes, but check your lease first, since some buildings restrict copies of entry keys. Restricted keys require authorization from the owner or manager, and we'll explain what we need before we cut anything.
Can you copy a car key?
A plain metal car key can be cut, but many vehicles use chips that need programming, and the facts differ by make, model, and year. We confirm by VIN or in person instead of guessing, and we say plainly if a particular key is dealer-only.
How many spare keys should I have made?
Enough that no one is stuck, but not so many that you lose track. For a home, one for each regular occupant plus one trusted spare is common. For an office, keep a written list of who holds which key, so you can tell when it is time to rekey instead of copying more.
