What does key duplication cover in Hermosa Beach?
Key duplication means cutting a new key that matches an existing one so it operates the same lock. In practice that covers a lot of small jobs: a spare house key for a partner or a dog walker, an apartment key copy for a new roommate, an office key for an extra employee, a duplicate deadbolt key, and the small flat key that opens a mailbox. Each one is a different blank, a different cut, and sometimes a different conversation about who is allowed to have a copy.
Wilshire Lock & Key has been cutting keys since 1987. David, our owner and lead technician, oversees how the work is done. We operate from a storefront at 10740 Wilshire Blvd in Westwood and from mobile service vans, so in Hermosa Beach you can either bring a key to us or ask a van to come to you. Some jobs suit one better than the other, and we will say which when you call.
This page is about copying keys. If your real problem is a lock that is failing, a key that has snapped off inside the cylinder, or a former tenant who may still hold copies, the right fix is probably something else. We point you to those services further down rather than selling you a copy that does not solve the problem.
Why does the quality of a key copy matter?
A key is a small precision part. The cuts on its blade lift the pins inside the lock to exact heights, and a copy that is slightly off will often still go in and still turn, but only if you wiggle it, lift the door, or push the key in a certain way. That habit puts extra wear on the lock and on the key, and a worn or weakened key is the one that eventually snaps.
The usual cause of a bad copy is the source. A copy made from a worn key inherits the wear and adds its own small error. A copy made from that copy adds another. After a few generations, you have a key that barely resembles the original cut. This is common with the one key everybody in a household has been duplicating for years.
Wrong blanks cause trouble too. Many keys look identical at a glance but differ in the keyway profile, the length, or where the shoulder stops the key. A blank that is close but not correct can bind in the lock or fail to seat fully.
Signs that a copy was not cut well:
- The key only works when you jiggle it, pull it back slightly, or lift the door as you turn.
- The key goes in rough or stops short of fully seating.
- The deadbolt does not throw all the way, or it feels gritty.
- The copy works in the front door but not in the secondary lock it should also open.
- Fresh metal burrs are still on the blade, or the key leaves brass dust in your pocket.

Call (213) 577-1366How do we duplicate a key, step by step?
Most standard house, apartment, office, and mailbox keys follow the same basic path. It is quick when the key is straightforward, and it slows down only when something about the key or the situation needs a second look.
- Look at the key and ask what it opens. We check the brand markings, the keyway profile, and whether it belongs to a front door, deadbolt, gate, padlock, office door, or mailbox.
- Choose the matching blank. We match the profile, length, and shoulder position instead of grabbing something that looks close.
- Inspect the original. If it is bent, badly worn, or corroded, we tell you before cutting, because the copy will only be as good as the source. We talk through other options if the original is past saving.
- Cut the copy on calibrated equipment and remove the burrs so no metal shavings are carried into your lock.
- Test the new key in the actual lock, not just against the original. It should enter smoothly, turn without force, and throw a deadbolt fully, repeatedly.
- Hand over both keys and tell you what we found. If the original was worn, we say so, so you can retire it instead of using it for the next copy.
What affects the cost of key duplication?
We do not quote 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:
Beyond those, a plain brass house key is the lighter-cost end of the range, and a restricted or high-security key is at the other end. We explain what applies to your key before we cut anything, so there are no surprises when the work is done.
- The type of key: a standard house or mailbox key is a different job from a high-security or restricted key.
- Whether the blank is common or has to be sourced or ordered.
- How many copies you need, since a handful cut together is not the same as a single key.
- The condition of the original, and whether it needs extra work or a different method to copy well.
- Whether authorization is required before we can copy it.
- Whether you come to the storefront or a mobile van comes to you.
- The time of day or night you call, since after-hours service is a different arrangement from a daytime walk-in.
Can restricted, high-security, or 'Do Not Duplicate' keys be copied?
Sometimes, but not the way a standard key is. Restricted keyways are protected so that blanks are not freely available, and copies are normally tied to authorization from whoever the system is registered to. Depending on the system, that can mean paperwork, proof of ownership, or a request through the manufacturer or a dealer. We confirm what applies to your specific key in person or by looking at it, rather than guess over the phone. If a particular key can only be handled through a dealer or the manufacturer, we tell you plainly instead of pretending otherwise.
A 'Do Not Duplicate' stamp on a key is a request, not a security feature. The metal itself is usually the same as any other key. We treat the stamp seriously and ask about authorization, and we may decline a copy when we cannot reasonably confirm you are entitled to one. If you want real control over who can copy your keys, that is what high-security locks are for, because the protection lives in the keyway and the registration instead of a stamp.
Offices have a related concern. In a building with a keyed-alike or hierarchical setup, a copy of a master key opens many doors. If your business runs on that kind of arrangement, or you are considering one, read about a master key system before making extra copies of the top-level key. We handle commercial key duplication for office doors, storage rooms, and file cabinets, with the same authorization questions applied.

Call (213) 577-1366What should Hermosa Beach residents know about key copies in ZIP 90254?
Hermosa Beach is under 1.5 square miles, and nearly all of it sits inside ZIP 90254. The housing is dense: small-lot beach cottages from the 1920s onward, plenty of them converted or rebuilt as multi-story townhomes, and many duplexes, triplexes, and small apartment buildings. That mix shapes what we see on the key-cutting side.
Rental turnover is the big one. In the Sand Section, and along the Pacific Coast Highway and Aviation Boulevard corridors, a high share of residents rent and units change hands often. Every move-in tends to create another copy of the key, and nobody tracks how many exist. When a Sand Section duplex or triplex turns over, copying keys for the incoming tenant is routine, but if the previous tenant may have kept copies, a duplicate does nothing for security. That is a lock rekey job, and property managers who handle several units often fold both into one visit. Our page for locksmith services for landlords covers the turnover side in more detail.
The ocean sets the condition of the hardware. Everything in the city is within a few blocks of salt air, so exterior locks, hinges, and gate hardware corrode routinely, and keys that live on a ring near the beach pick up the same wear. Older wood-frame cottages also deal with marine layer damp, which swells doors and makes deadbolts stick. Before we cut a copy, we check whether the sticking is the key or the lock, because a good copy of a key that is already worn will not feel any better in a stiff, salt-worn deadbolt.
Where this comes up around town:
- Walk-street and alley-access cottages near The Strand: a spare key held by a neighbor or family member is much easier to arrange than a lockout call, so a good copy cut ahead of time is worth it.
- Hermosa Valley and East Hermosa: side-gate and garage keys along the Hermosa Valley Greenbelt are often separate keys on a ring, so bring every key you want copied, not just the front door.
- North Hermosa and South Hermosa: older townhomes and cottages often carry dated hardware, so the key itself may be a rare or aging profile. Bring it in and we will look at it.
- Pier Plaza and downtown: workplaces and food-and-drink businesses regularly need extra employee keys, which are commercial key duplication jobs, with authorization from whoever holds the keying.
- Apartment buildings on the PCH and Aviation corridors: an apartment key copy generally needs the building manager or owner to agree, and we ask.

Call (213) 577-1366Can you come to me for mobile key duplication?
Yes, in many cases. Our vans carry key-cutting equipment, and we serve Hermosa Beach from our Westwood storefront, about 19 miles away. Mobile key duplication makes the most sense when several keys need cutting at once, such as a multi-unit building, an office where staff cannot leave, or someone who cannot travel. Our mobile locksmith page explains how mobile visits work in general.
One honest caveat: a van cannot carry every blank for every key. When you call, tell us what you can about the key, such as brand markings, what it opens, and whether it has a restriction stamp, and we will say whether we can cut it on-site or whether it is better handled at the storefront.
Mailbox keys are a special case. They are small, simple, and easy to lose, but who controls the lock matters. If it is a building-owned mailbox we can usually cut a copy. If the mailbox is controlled by someone else, such as the building owner or the postal service, we will say so instead of guessing. When the lock itself is damaged or the key is gone entirely, you are looking at mailbox lock replacement instead of a copy.
Why call Wilshire Lock & Key for key copies?
We have been in business since 1987 and serve 140 cities across Los Angeles and Ventura counties, Hermosa Beach among them. We are one company with a real storefront and our own mobile vans, not a call center that passes your job to whoever is available. When you call (213) 577-1366, the phone is answered 24 hours a day, 7 days a week, all year, and the person who handles your job works for us.
David oversees the work. That matters for key duplication because small details, like choosing the correct blank or declining to copy a key we cannot confirm is yours to copy, are judgment calls, and he sets the standard for them.
California requires locksmith companies to hold a license from the Bureau of Security and Investigative Services, known as a BSIS LCO license. Ask any locksmith for it before they work on your locks, including us. It is a fair question and a reasonable way to tell a real company from a stranger with a van.
We would rather tell you a copy is a bad idea than cut it and move on. If we see a worn key, a failing lock, or a situation where extra copies make you less secure, you will hear that from us before we pick up the cutter.

Call (213) 577-1366When is a copy not the right answer?
Duplication is the simplest locksmith job, which is why it is easy to use it as a patch for a bigger problem. A few situations where we would suggest something else:
If you are unsure which category you are in, call and describe what is happening. We will tell you whether a copy is enough.
- You do not know who else has keys. Copies add to the problem. Rekeying the lock makes every old key useless, and you then cut fresh copies from the new key.
- The key is part of a broken or snapped piece. A copy cannot be made until the fragment is dealt with, and you need broken key extraction first.
- The lock itself is corroded, loose, or past repair, which is common with salt-worn exterior hardware. A perfect copy will not fix it, and lock replacement is the better route.
- The key only works with effort. If the original has always been hard to turn, we check the lock before duplicating it, because the problem may not be the key.
Frequently asked questions
How long does it take to copy a house key?
A standard house, apartment, or deadbolt key is normally cut while you wait at our Westwood storefront. We do not promise exact times on the phone, because it depends on the key, whether the blank is in stock, and whether the original needs a closer look first.
Can you duplicate a key in the middle of the night?
Our phone is answered 24 hours a day, 7 days a week at (213) 577-1366. Call and tell us what the key is and where you are in Hermosa Beach. We will say what we can do at that hour, including whether a mobile visit makes sense, since not every blank travels in the van.
Can you copy a key that says 'Do Not Duplicate'?
Possibly, but not automatically. The stamp is a request, not a lock-level protection, and we ask about authorization. If the key belongs to a restricted system, the copy may need approval from the registered owner or go through the manufacturer or a dealer. We will tell you plainly which applies.
Can you make a key if I have lost the original?
Sometimes. Depending on the lock, there may be a way to make a working key from the lock itself, and in other cases rekeying or replacing the lock is the more sensible route. We figure out which when we see the lock, and we ask for some proof that you are entitled to access it.
Do you copy mailbox keys in Hermosa Beach?
Yes, for mailboxes where the lock belongs to the building or owner and the key is a standard type. If the mailbox is controlled by someone else, such as the property owner or the postal service, we will say so. If the lock is broken or the key is gone, replacing the lock is usually the better answer.
I rent my apartment. Can I just copy my key?
Check your lease or ask the property manager first. Many buildings expect to approve extra copies. We may ask for confirmation that the building allows it, particularly for apartments in small multi-unit buildings or for restricted keys.
Do you do office and commercial key duplication?
Yes. We cut copies for office doors, storage rooms, and cabinets. If your building uses a master key arrangement, we ask who is authorized to request copies, because a copy of the wrong key could open far more than one door.
Why does my new copy stick when the original works fine?
The usual causes are a poorly matched blank, a copy made from a worn original, or burrs left on the blade. Bring both keys back and we will look at them. It is also worth checking the lock, since salt air and damp can make a deadbolt stiff in Hermosa Beach even when the keys are fine.
