Why does a spare house key matter more than people think?
Most key duplication calls begin the same way. Someone has one working key and wants a second before something goes wrong. That is the right instinct. A spare house key held by a family member, a neighbor you trust, or a place only you know about saves far more trouble than any repair after the fact. If you ever do end up outside your own front door, we handle that too through our house lockout service, but a good spare means you may never need it.
Spare keys also solve ordinary household problems. Teenagers need their own, a house sitter needs one for a week, a cleaner needs one that you can take back later, and a contractor may need access while you are at work. Handing out your only key in any of those cases is how people end up locked out or, worse, unsure who still has a way in.
The catch is that a copy is only as good as the process behind it. A poorly cut key can feel fine in the lock for a week and then bind, stick, or fail on a cold, damp morning. We cut keys to work smoothly the first time, and we test them in the lock before you pay for them.
What makes a duplicate key actually work?
A key works because the cuts along its blade lift each pin inside the lock to exactly the right height. Key duplication is the job of reproducing those cuts and the key's groove profile, called the keyway, so the new key behaves like the original. Small errors add up. A cut that is slightly shallow or slightly off its spacing makes the key rough, and a rough key wears the pins inside your lock faster than it should.
The starting point matters as much as the machine. Every copy of a copy drifts a little from the factory original. If your only key is already worn, the duplicate inherits that wear and sometimes adds to it. When we can, we prefer to work from your best, least worn key, or from the original if someone still has it. When the key is badly worn, we may cut by the lock's code or by taking the lock's measurements instead of tracing the tired key.
The blank also matters. A blank must match your lock's brand, keyway, and thickness. A blank that is close but not exact can slide in and turn stiffly, or turn once and then jam. We match the blank to the lock rather than to whatever is nearest on the rack.

Call (213) 577-1366How do we copy your key, step by step?
The process is simple, and we do it the same careful way whether it is a front door key or a small mailbox key.
- You call (213) 577-1366 and tell us what the key opens: a front door, a deadbolt, an office door, a mailbox, a gate, or something less common.
- We ask a few questions about the key itself, such as any stamping on it, how many keys exist, and whether it looks like a standard key or a restricted one.
- We look at the original key and check its condition. If it is worn, bent, or already a copy of a copy, we tell you plainly and suggest the better way to cut from it.
- We select the correct blank, matching the brand, keyway, and thickness to your lock.
- We cut the new key and remove the burrs so it does not drag or scratch the inside of the lock.
- We test the duplicate in the actual lock, and we test the original too, so you know both keys turn the same way.
- If the lock itself is stiff, damaged, or failing, we say so before you leave with a key that only hides the problem.
Which keys can we copy, and which need extra steps?
Most keys are straightforward, but not all of them are. Here is how we sort them out honestly.
- House and apartment keys: standard residential keys, including your duplicate deadbolt key, are the most common copies we cut. For an apartment key copy, we may ask you to confirm that you are allowed to copy it, since a lease or building rule can prohibit it.
- Mailbox keys: small, flat mailbox keys are routine to copy when they are an ordinary type. If the mailbox lock is damaged or the key has been lost entirely, the better route is often a new lock, covered under mailbox lock replacement.
- Office and commercial keys: office key duplication is common for small businesses, but we ask who has authority to approve more copies. If your building runs on a master key arrangement, copying must follow that structure, and our master key system work explains how those are organized.
- High security and restricted keys: these use patent-protected or controlled keyways, and the maker restricts who may order more. We will not cut them without proper authorization from the account holder. Sometimes we can handle it ourselves, and sometimes the maker or a dealer must be involved. We tell you which case you are in before any work starts, and our page on high security locks explains how they differ.
- Keys stamped 'Do Not Duplicate': that stamp is a request, not a technical barrier. Plenty of keys with it are ordinary keys, and plenty of truly restricted keys carry no stamp at all. We look at the keyway and the lock instead of trusting the stamp, and we ask about your authority to copy it.
- Vintage and unusual keys: older keys for old hardware sometimes cannot be copied by a standard machine. We look at them in person and tell you what is realistic.

Call (213) 577-1366What 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 things that move the cost up or down.
The type of key is the biggest factor. A standard residential key is the lighter-cost option. A high security key with a controlled keyway, an unusual profile, or a dealer-only blank takes more effort, more verification, and sometimes more than one source for the blank.
The condition of the original matters. A clean key traces easily. A worn or bent key may need extra work, or may call for cutting by the lock's code or measurements instead.
The number of copies matters, and so does whether you need them at your door or at our counter. A copy made at our Westwood storefront is usually the more economical route when you can drive over. A visit from one of our mobile vans adds travel, which matters in Palos Verdes Estates, roughly 24 miles from our base.
Finally, if the real problem is a worn or failing lock, we would rather tell you that than keep cutting keys for it. We give you a clear price before work begins, and you decide.
Key duplication in Malaga Cove, Lunada Bay, Valmonte and Montemalaga
Palos Verdes Estates is a master-planned city from the 1920s, and its housing is almost entirely single-family. That shapes how keys get copied here. In Malaga Cove and Valmonte, many homes date from the 1920s through the 1940s, and many of them still carry vintage mortise locks and original hardware. Those keys are often long, old, and worn from decades of use. A fast copy from a tired original is a poor idea. We prefer to look at the lock, check how the key sits and turns, and cut so the new key is smoother than the old one, not rougher.
Some of those older locks use keys that are not stocked as common blanks, and we tell you right away if a particular key needs a different approach. Where the lock itself is the real issue, we point you to lock repair rather than leave you with a copy that strains hardware you want to keep.
The coast adds its own wear. Salt spray and persistent fog corrode exterior locks and hinges fastest on homes near Bluff Cove and Lunada Bay, and marine damp swells older wood doors for much of the year. A swollen door makes a key work harder, and a corroded lock makes a key grind. If you have a key that has started to stick in a bluff-top home, copying it will not cure that. We check the lock when we cut the key so you know the difference.
Montemalaga and Lunada Bay bring mid-century ranch and view homes, where families often want a spare for each driver, a hidden backup, and one for a house sitter. One local scenario we see is rekeying after estate sales and property transfers. In that case a copy is the wrong first step, because you do not know how many old keys are out there. We usually suggest rekeying the locks first and then cutting however many new keys you need.
The whole city shares ZIP code 90274, but each street has its own mix of door ages and hardware, so we ask what is on your door before we promise anything.
Locked out or need a locksmith now?
We answer around the clock, every day of the year.
Call (213) 577-1366Can you come to me, or do I have to drive to Westwood?
Our storefront is at 10740 Wilshire Blvd in Westwood, and we also run mobile service vans. From Palos Verdes Estates the storefront is a real drive, so for many people the practical answer is to have us come to you. Our mobile locksmith service is built for that.
What we can do on site depends on the key. Many common keys can be handled where you are. Some restricted keys, vintage keys, or hard-to-find blanks need verification, a specialty blank, or work in our shop. We will say so on the phone instead of sending a van and finding out later.
If you have a key that is stuck, broken in the lock, or already lost, tell us when you call. That changes the job from a simple copy to something else, and we would rather plan it correctly from the start.
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. That is a lot of keys, and a lot of lessons about what goes wrong with copies.
We are one company. You are not calling a dispatch center that hands your request to a stranger. The people who answer the phone, cut the key, and stand at your door work for the same business, and David, the owner and lead technician, oversees how the work is done.
We have a storefront and mobile vans, so we can cut at the counter or come to you. The phone at (213) 577-1366 is answered 24 hours a day, 7 days a week, year-round, so you can ask about a key whenever it occurs to you.
One more point 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. Asking is normal, and a good company expects the question.
When a copy is not the right fix
Sometimes the honest advice is not to copy the key. If you have lost a key and do not know who found it, a copy of your remaining key does not make the door safer. Rekeying does. If a business has lost track of who holds keys, a commercial locksmith can reorganize the system instead of cutting more of the same keys.
If your key is worn so badly that the copy will be worse, we say so. If your lock is corroded, we say so. If you simply need another working key and everything else is sound, we cut it, test it, and you are done.
Frequently asked questions
Can you copy a key at my home in Palos Verdes Estates?
For many common keys, yes. Our mobile vans can handle a lot of standard house, deadbolt, and mailbox keys where you are. Restricted, vintage, or hard-to-find keys may need extra verification or shop work, and we tell you which applies when you call (213) 577-1366.
Do you copy keys marked 'Do Not Duplicate'?
We look at the key and the lock first. The stamp is a request, not a real security feature, and many keys carrying it are ordinary. If the keyway is genuinely restricted, we need proper authorization from the account holder, and we explain what that involves before we cut anything.
What if my only key is old and worn?
We will tell you before cutting. A copy traced from a worn key inherits the wear, so we may cut by the lock's code or measurements instead. If the lock itself is the reason the key is worn, we point that out too.
Can you duplicate a deadbolt key?
Yes. A duplicate deadbolt key is a routine job. We match the blank to the deadbolt's brand and keyway, then test the new key in the actual lock. If the deadbolt turns stiffly, we suggest repair or replacement rather than just adding another key.
Can you copy a mailbox key?
Usually, yes, when the key is an ordinary type. If the key is lost, the lock is damaged, or the mailbox is shared and controlled by a property manager, the route may be different, and we explain the options when you call.
Can I get extra keys for my office or business?
Yes, with the right approval. We ask who has authority to order copies, especially if your building uses a master key arrangement. Cutting more keys for a restricted or master-keyed system has to follow how that system was set up.
Is it better to copy my keys or rekey the locks?
If you trust everyone who holds a key and just need more of them, copying is the lighter-cost option. If a key is lost, a tenant moved out, or you bought a home or handled an estate, rekeying is the safer move because it makes old keys useless.
How long does a key copy take?
A standard copy is quick once we have the key and the correct blank in hand. Restricted and unusual keys take longer because of verification and blank sourcing. We tell you what to expect when we know what key you have.
Do I need to prove the key is mine?
For ordinary keys, we usually just ask a few questions. For restricted keys, office keys, and apartment keys, we may need proof that you are allowed to copy them. That protects you as much as the person who owns the lock.
