Why does a copied house key sometimes fail to work?
A key copy is only as good as the key it was cut from and the lock it has to turn. Most failed copies trace back to one of three things: a worn original that passed its wear on to the copy, a blank that did not truly match the keyway, or a cut that was slightly off at one depth. Any one of them gives you a key that slides in, wiggles, and refuses to throw the deadbolt at the worst possible moment.
In Rancho Palos Verdes there is a fourth cause people rarely suspect, and that is the lock itself. Coastal bluffs get direct salt spray and a persistent fog belt, which speeds up corrosion on exterior hardware. In parts of the city, ongoing ground movement can shift a house enough that a bolt drags against its strike plate. A perfectly cut key can feel like a bad copy when the real trouble is a gritty cylinder or a door that no longer lines up with its frame. We check for that before we blame the key.
That is why we treat duplicate keys as a small precision job and not a vending-machine transaction. You hand us one key, and you leave with copies that behave the same way as the original, in your lock, on your door.
How do we duplicate your keys, step by step?
The process is simple, but each step matters. Skipping any of them is how people end up with a drawer full of keys that almost work.
- We look at your original under good light, checking for wear, bends, stamped markings, and whether it is a standard key, a high-security key, or a restricted one.
- We identify the keyway and choose a blank that matches by brand and profile, not one that merely looks close.
- We cut the copy, working from the key's code or a clean original whenever possible, rather than from a worn copy of a copy.
- We deburr the new key and compare the cuts against the original so there are no rough edges to chew up your pins.
- We test the key in the actual lock when we can, whether that is your front door, your deadbolt, or your mailbox, and turn it several times. We also test the original, since a tired original sometimes tells us something.
- If we find a sticky cylinder, a misaligned bolt, or corrosion, we tell you what we see and what the options are before doing anything beyond the copy.

Call (213) 577-1366Which keys can we copy?
Most keys can be copied. A few need extra steps, and a few need paperwork. Here is how it breaks down for what people in Rancho Palos Verdes typically bring us.
- House key copy and spare house key: standard residential keys for front doors, side doors, and garage entry doors. This is the most common request.
- Duplicate deadbolt key: deadbolts often use a different keyway from the knob or handle set, so we match each key to its own lock instead of assuming one blank fits both.
- Apartment key copy: we can cut copies of most apartment and condo keys. Check your lease or building rules first, since some properties require management approval for extra keys.
- Office key duplication and commercial key duplication: suite doors, storefront locks, desks, file cabinets, and back-of-house doors. If you want a structured system with controlled access, ask about a master key system.
- Mailbox key duplication: mailbox keys are small, and they are easy to lose. If you have a key to copy, it is a quick job. If you have no key at all, you are looking at a lock change instead, which we cover under mailbox lock replacement.
- High security key duplication: these keys use tighter tolerances or special profiles. Copying them takes the right blank and the right machine, and we will tell you plainly if a particular key has to be cut at the storefront. More on the locks themselves is on our high-security locks page.
- Restricted key duplication: restricted keyways are controlled so that copies cannot be cut casually. Expect to show an authorization card, a record of ownership, or contact the key system's owner. This protects you, and we will not skip it.
- Car keys: a key with a chip or remote is not a plain cutting job. We confirm by VIN and in person what your vehicle needs, and we say plainly when a dealer is the only route. If you have lost every key, see lost car key replacement.
Should you copy the key, or rekey the lock?
Copying is the right move when you know exactly who holds every key and you simply need more of them: a spare for a family member, a backup for a neighbor, a set for a house sitter. It is usually the more economical route compared with changing any hardware.
Copying is the wrong move when you do not know who has keys. If a key went missing, a tenant moved out, a contractor kept a set, or you bought a home and have no idea how many copies exist, another copy just adds to the problem. In those cases you want the lock changed so old keys stop working, and that is what lock rekeying does, usually without replacing the hardware.
One more situation: if the lock is worn out, corroded, or the key sticks even when new, copying a key for it is money spent on a lock that is already failing. We would rather tell you that at the counter than send you home with keys for a lock that will not last.

Call (213) 577-1366What affects the cost of key duplication?
We are not going to quote you a figure on a web page, because the honest answer depends on what is in your hand. Here is what moves the cost of a job, from small to large.
- The type of key: a standard house key is the simplest. High-security and restricted keys take specialized blanks and more careful cutting.
- How many copies you need: a single spare is different from a set for a family, a rental, or a team of employees.
- The condition of the original: a clean original cuts straightforwardly. A worn or bent one may need extra work, or we may recommend cutting from code instead.
- Authorization requirements: restricted systems need documentation, which can add a step but protects your property.
- Where the work happens: a copy at our storefront is different from a mobile visit to your home or business, where travel and the hour of the call play a part.
- What we find in the lock: if the copy exposes a worn cylinder, we will tell you. Any repair or replacement is a separate decision, and it is always yours.
What does key duplication look like in Rancho Palos Verdes?
Rancho Palos Verdes is mostly 1950s to 1970s ranch and view homes on hillside and bluff lots, with larger estate properties in Portuguese Bend and condo and townhome communities concentrated on the Eastview side. Houses of that age often still carry original or decades-old hardware, and the keys have usually been copied several times over. A copy of a copy of a copy is where fit problems begin, so for older homes in 90275 we like to cut from the cleanest key you have, and we are happy to look at a bundle and tell you which ones are worth copying from.
Salt and fog are the second local factor. On bluff-top homes, exterior locksets corrode faster than they would inland, and a corroded key will cut a poor copy. If your house key looks pitted or the cylinder feels rough, a duplicate may simply carry the problem forward. In that case we may suggest lock replacement on the exposed door and copies cut once the new lock is in.
Ground movement is the third. Near Portuguese Bend and Seaview, shifting structures can rack door frames so that deadbolts and strike plates no longer line up. Homeowners there sometimes assume the key is the problem and ask for a new copy, when the bolt is actually binding in the frame. We check the door and the bolt with the key in hand, and if it is an alignment issue we will say so. Fixing that is a separate piece of work, and it falls under lock repair.
The neighborhoods vary in what they need. In Miraleste and Mira Catalina, hillside homes tend to need extra house keys and duplicate deadbolt keys for family, caretakers, and service people. In Eastview, condo and townhome owners often ask about apartment-style key copies and need to check HOA rules about common doors and shared gates. Many tracts in the city are HOA-governed, so it is smart to confirm who may hold keys to shared areas before you order extras. Over at Golden Cove Shopping Center, shop owners and staff need commercial key duplication for storefront and back-room doors, and we can cut those keys, keeping a clear record of who holds what.

Mobile key duplication is useful when you cannot leave a property, when you need keys for several doors in one visit, or when it is the middle of the night and the only key you have is the one in your pocket. Read more about mobile locksmith service in the city.
We will be straight about limits. Standard house, deadbolt, and mailbox keys are the easiest to handle at your door.

When you call, tell us what the key looks like and any markings on it, and we will say whether it is a visit to you or a trip to Wilshire Boulevard.
Why call Wilshire Lock & Key for copies?
We have been in business since 1987, which means we have cut keys for a long list of lock brands and seen most of the ways a copy can go wrong. David, the owner and lead technician, oversees the work, so there is someone accountable for how your keys turn out.
We run a storefront at 10740 Wilshire Blvd in Westwood plus mobile vans. When you call (213) 577-1366, you reach us, not a dispatch middleman who passes your job to whoever is free. We answer 24 hours a day, 7 days a week, year-round, and we serve 140 cities across Los Angeles and Ventura counties.
One more point worth knowing as a customer: California requires locksmith companies to hold a BSIS LCO license, and you should ask any locksmith you hire for it. That applies to everyone in this trade, and it is a reasonable question before anyone cuts keys to your home or business.
Frequently asked questions
Can you copy a key stamped Do Not Duplicate?
The stamp does not physically stop a key from being cut, but we do not treat it as meaningless. If a key is stamped that way or belongs to a restricted system, we ask for authorization, such as a card or a letter from whoever controls the keys. If you are the owner and can show it, we can usually help. If the key belongs to an employer or a landlord, we will ask you to get their approval first.
How many spare house keys should I have made?
For most households, one or two spares kept in trusted hands is plenty. More copies mean more places a key can be lost. If you are keeping track of who holds a key, a copy for each person is fine. If you have lost track, rekeying is a better move than adding more copies.
Can you copy my apartment key?
Usually yes, since most apartment and condo keys are standard. Check your lease or building rules first, because some properties require management approval for extra keys or use restricted keyways. If yours is restricted, we will need authorization before we can cut it.
Do you duplicate mailbox keys?
Yes. Mailbox keys are small and cut quickly if you have the original. If you have no key at all, copying is not an option, and the lock typically has to be replaced. Our page on mailbox lock replacement covers that case. If your mailbox is part of a community or HOA setup, check who manages it before you replace anything.
Can you duplicate a car key?
It depends on the key and the vehicle. A plain metal key is a simple cut. A key with a chip or remote involves programming, and what your car needs is something we confirm by VIN and in person. In some cases a dealer is the only route, and we say so plainly. If you have no working key at all, that is a different service from copying.
The copy you made sticks in my lock. What do I do?
Bring it back along with the original and we will compare them. Sometimes the copy is the issue and we recut it. Sometimes the lock is worn, corroded by salt air, or out of line because the door has shifted, and the better fix is to address the lock. Either way, we will tell you what we find before suggesting any additional work.
How much does key duplication cost in Rancho Palos Verdes?
It depends on the key type, how many copies you need, the condition of the original, whether authorization is required, and whether we come to you or you visit the storefront. A standard house key is the simplest job. High-security and restricted keys take more care. Call (213) 577-1366 and describe what you have, and we will walk you through what drives the cost for your situation.
Are you available at night or on weekends?
Our phone is answered 24 hours a day, 7 days a week, year-round. Whether a given key can be cut at your door that hour depends on the key type. Standard keys are straightforward, while some restricted or high-security keys may need to wait for the storefront. We will tell you honestly when you call.
What if I only have one key and it is the last one?
Do not wait until it breaks or goes missing. Copy it while it is still in good shape, because a worn original gives a worse copy each time. If the single key is already bent or cracking, bring it in soon and we will cut from the cleanest option available.
