Why a spare house key matters more near the coast
Most people think about a spare house key only after they need one. Then the sequence is predictable: the one key is in a jacket pocket on the beach, a wetsuit bag, or the other car, and nobody else has a copy. Key duplication is the quiet, inexpensive-in-effort job that prevents that evening from happening. A spare cut today is a lockout you probably never have.
Malibu adds its own wrinkles. Homes here sit in salt air and a persistent marine layer, which corrodes exterior metal faster than inland conditions do and swells wood doors when it is damp. A key that has lived on a ring in that air, and in that lock for years, wears. Copying from a badly worn key can produce a copy that is worse than the original. So part of our job is judging whether the key you hand us is a good source, not simply running it through a machine.
This page covers what we actually copy, how we do it, what changes the cost, and where copying is the wrong move. If you already know what you need, call (213) 577-1366 at any hour and we will talk it through.
How we duplicate a key, step by step
Key copying looks simple from the counter, but small errors in the process are what cause a copy that sticks, grinds, or works on Tuesday and fails on Friday. This is the order we follow.
- Identify the key. We look at the blank type, the brand stamped on the head, and whether it is a standard pin-tumbler key, a restricted profile, a high-security key, or something that needs a different approach altogether.
- Inspect the original. We check for bent shoulders, rounded cuts, and wear on the bitting. If the original is tired, we say so and discuss options before cutting anything.
- Match the blank. The copy has to be the right keyway and the right length, with the correct shoulder or tip stop. A close blank that is not exact is how keys end up binding in a lock.
- Cut and deburr. The cuts are made to the original's depth and spacing, then the burrs are removed so the key does not shed brass filings into your lock.
- Test in the actual lock when possible. A copy that matches the original on a machine can still behave differently in a lock that has its own wear. We try it, and if it is stiff we correct it.
- Hand it back with a clear note. If any copy is slightly stiffer than the original, or if the lock itself looks like the real culprit, we tell you instead of letting you find out later.

Call (213) 577-1366Which keys can we copy?
Most keys are straightforward. Some are not, and it is better to hear that before you drive anywhere. Here is the honest rundown by type.
- House key copy and spare house key: standard residential keys for entry locks are the most common request and generally the simplest.
- Duplicate deadbolt key: deadbolts often use a different keyway than the knob or handle set, so we match each key to its own lock rather than assuming one blank fits both.
- Apartment key copy: we can cut copies of ordinary apartment keys. If the key is stamped or marked as restricted by the building, or your lease requires management approval, we will ask about that first.
- Office key duplication and commercial key duplication: standard office keys are routine. Where a business uses a master key system, copies of the upper-level keys may need authorization, and we handle that carefully.
- Mailbox key duplication: mailbox keys are small, and many are a specific style. If the key is lost entirely rather than just needing a copy, the answer is usually a lock change, not a copy.
- High security key duplication: these keys use tighter tolerances or unusual cut patterns, and not every machine or blank handles them. We confirm what you have before promising anything.
- Restricted key duplication: restricted keyways are protected by the manufacturer so copies are controlled. These typically need proof of authorization, and in some cases only the manufacturer can supply the blank. We will tell you plainly if that is where your key lands.
Standard keys versus high-security and restricted keys
A standard key is cut on a blank that anyone can buy, which is exactly why standard keys are easy to copy and also why they offer limited control over who holds one. If you want control over who can duplicate your keys, that is a lock decision, not a key decision. Restricted and high-security systems exist to limit unauthorized copying, and that control is the point of buying them. If you are curious about moving to that kind of system, our page on high-security locks explains how they work.
One thing to be careful of: a stamp on the head of a key reading something like do not duplicate does not make it legally or physically uncopyable. It is a request, not a barrier. A truly restricted system works differently, because the blanks and the machines are controlled. We don't copy keys from a restricted system without the authorization that system requires, and if we cannot cut it we will say so up front and point you to who can, even if that is the manufacturer or a dealer.

Call (213) 577-1366When copying the key is the wrong answer
Duplication is a good fix for a good key and a bad fix for a few other situations. These are the cases where we steer people somewhere else.
If the original is worn, a copy of a copy of a worn key is a gamble. Each generation drifts a little further from the factory cuts. For a key that is already sticking, we would rather work from the lock's code or rekey the lock than hand you a third-generation key that will not turn reliably.
If you have lost a key and do not know where it is, a copy does nothing about whoever might find it. In that case, lock rekeying changes the pins inside the lock so the lost key stops working and the new keys do. This is often the more sensible path after a rental turnover, a move, or a lost set.
If the lock itself is damaged, sticking, or corroded, a new key will not fix it. A fresh copy in a failing lock just fails with a newer key. We look at the lock when it is part of the problem.
Can you come to me for mobile key duplication?
Wilshire Lock & Key runs a storefront at 10740 Wilshire Blvd in Westwood plus mobile service vans, so we can often bring the work to you. Whether we can cut a given key at your door depends on the key type: many standard keys are easy to handle on a call, while some high-security or restricted keys need shop equipment or manufacturer authorization. When you call, describe the key and we will tell you which route makes sense.
Malibu is about 17 miles from our Westwood base, and it is a long, spread-out city, so if you have a particular location in mind such as a canyon road or a beachfront address, give us the address and we will work out the logistics with you. Our full mobile service is covered on our mobile locksmith page, and the phone is answered around the clock at (213) 577-1366.
What affects the cost of key duplication?
We don't quote numbers on a web page because the honest answer depends on the key in your hand. Here is what moves the cost, in rough order of importance.
The type of key matters most. A standard house key is the lighter-cost job. Keys with unusual blanks, tight tolerances, or restricted profiles take more time, special equipment, or controlled blanks, and that is reflected in the work.
Quantity changes the picture slightly, since setup is the same whether you need one copy or several. If you are cutting a set for family, a rental, or an office, it usually makes sense to do it in one go.
Where the work happens matters. Copying a key at our shop is usually the more economical route compared with arranging a visit by a mobile van, though a visit makes sense when you cannot get to us or when the key must be checked in the lock itself.
Time of day plays a part. Phones are answered at all hours, but after-hours work is handled differently from a planned daytime visit.
Condition of the original also counts. If the key needs extra care, or if we recommend a different fix, that changes what the job looks like. When you call (213) 577-1366, we will ask a few questions and tell you how pricing works for your specific key before we start.

Call (213) 577-1366Key duplication around Malibu: what we see locally
Malibu is a coastal city split across ZIP codes 90265 and 90263, with beachfront homes along Pacific Coast Highway, hillside and canyon estates on large lots, and long-standing mobile-home communities such as Paradise Cove and Point Dume Club. Each setting changes how keys get used and lost.
In oceanfront areas such as Carbon Beach and Broad Beach, keys spend their lives in salt air. Brass and plated keys can pit and wear faster, and a key that sticks in a coastal door is often a sign the key is tired, the lock is corroding, or both. This is exactly the situation where we check the original before copying it, and where we may suggest replacing worn hardware. Beach house lockouts in Malibu Colony and on Point Dume are a common reason people come looking for a spare in the first place.
Short-term and vacation rental owners near the Zuma Beach area often need several keys cut at once so cleaners, managers, and guests each have their own. If keys are changing hands often, the cleaner approach is to rekey between guests rather than keep multiplying copies. We cover that in more depth on our Airbnb and vacation rental locksmith page.
Canyon estates off Latigo Canyon and Corral Canyon often have a gate in addition to the front door, and gate padlocks or gate lock keys are copied just like any other key, as long as we can identify the blank. If the gate hardware itself is failing rather than the key, that is a gate lock repair job. Gated enclaves such as Serra Retreat and the guard-gated Malibu Colony may have their own rules about who can hold access keys, so check with your association before you order extras.
A meaningful share of homes along the eastern coast are recent rebuilds after the wildfires, with new door and lock hardware. New hardware usually comes with only a limited set of keys, and once the house is occupied, making spares is among the first small jobs worth doing.
Why call Wilshire Lock & Key for your spare keys
We have been in business since 1987 and serve 140 cities across Los Angeles and Ventura counties, Malibu among them. That is long enough to have seen nearly every kind of key and every way a copy can go wrong.
You deal with one company. There is no dispatch middleman passing your call along: we have a storefront in Westwood and our own mobile vans, and the person who answers the phone is part of the same operation that does the work.
David, the owner and lead technician, oversees the work, so questions about an unusual key do not get lost between desks.
We will also tell you when a copy is not the right answer. Sometimes the better move is a rekey, a replacement, or a different lock entirely, and we would rather tell you that than cut a key that will not solve your problem.
One note on licensing: California requires locksmith companies to hold a BSIS LCO license, and you should ask any locksmith you hire to show it, including us. Asking is a reasonable step, and a legitimate company will not mind.
If your need is bigger than a key, we also handle car key replacement and master key systems for offices and multi-door properties. And if you are replacing a mailbox lock rather than copying its key, see our mailbox lock replacement page.
Frequently asked questions
How long does it take to copy a house key?
For a standard house key, the copy itself is quick, and most of the time goes to matching the blank correctly and testing the result. Restricted or high-security keys take longer or may need authorization. We don't quote times over the phone because they depend on the key, but we can tell you which category yours falls into once you describe it.
Can you duplicate a key stamped do not duplicate?
Often, yes, if it is a standard key. That stamp is a request, not a technical lock. A key from a truly restricted system is different, since those blanks and machines are controlled and need proof of authorization. If you rent, check whether your landlord or building requires approval before ordering extras.
Do you offer mobile key duplication in Malibu?
We run mobile service vans in addition to our Westwood storefront, and we can often handle standard keys at your location. Some high-security or restricted keys need shop equipment or manufacturer authorization instead. Call (213) 577-1366, describe the key, and we will tell you which route fits.
Can you copy a duplicate deadbolt key and a knob key together?
Yes. Deadbolts often use a different keyway from the handle or knob lock, so each key is matched to its own lock. If you bring both, we will copy each separately and test them. If both locks are keyed alike, we will confirm that first.
Is it better to copy a key or rekey the lock?
If you still have the key and simply want a spare, copying is the straightforward choice. If a key is lost, a tenant or guest has left, or you are unsure who has copies, rekeying is usually the better option because it makes old keys stop working. Our rekeying page covers it in more detail.
My key is worn from salt air. Will a copy work?
It might, but copying from a worn key can pass the wear along to the new one. We check the original first. If it is too worn to copy reliably, we may suggest working from the lock itself, rekeying, or replacing corroded hardware so you are not carrying a poor copy.
Can you copy mailbox keys and office keys?
Standard mailbox and office keys are routine for us. If the office uses a master key system or the key is restricted, we may need authorization before cutting it. If a mailbox key is lost entirely, a lock change is usually the answer rather than a copy.
Can you duplicate high security keys?
Sometimes. High-security keys use tighter tolerances or unusual cut patterns, and some need controlled blanks that only the manufacturer or an authorized dealer can supply. We identify the key first and tell you honestly what is possible, including any dealer-only cases.
Are you available at night or on weekends?
Our phone is answered 24 hours a day, 7 days a week, year-round, at (213) 577-1366. Routine copies are usually easiest to plan during the day, but if you are locked out or stuck without a key, call any time and we will advise you.
