Why does a key copy go wrong so often?
A key copy looks like the simplest job in the trade, which is exactly why it goes wrong so often. A duplicate is only as good as the key it is cut from and the blank it is cut on. Copy a worn key and you get a slightly worse key. Copy that one and you get a key that drags across the pins, sticks in the cylinder, and eventually twists or snaps. We see this chain all the time: a third- or fourth-generation copy that sort of works until the morning it doesn't.
In Port Hueneme the problem has an extra layer. Keys that live near the ocean collect grit and film in pockets and on key rings, and the locks they turn are fighting salt air and damp all year. A key that has spent years forcing its way through a stiff, slightly corroded cylinder is usually worn itself. Cutting a fresh copy straight from it carries that wear forward and sometimes makes it worse.
That is why we never treat duplication as a push-the-button job. We look at the original first, decide whether it is a good enough master to copy from, and then test the new key in your actual lock. If the original is tired, we say so and explain your options before cutting anything.
How does key duplication work at Wilshire Lock & Key?
The process is short, but each step exists because we have seen what happens when it gets skipped. Here is how a normal duplication job goes, whether it happens in a van at your door or across our counter.
- Tell us what the key opens: a front door, a deadbolt, an apartment, an office, a mailbox, a gate. Read us anything stamped on the head of the key. Call (213) 577-1366 and we will say whether it is a job we can do at your location or one better handled another way.
- We inspect the original for wear, bends, hairline cracks, burrs and damage to the bow. A key with a bent shoulder or rounded cuts is a poor master, and we tell you that before going further.
- We match the blank to the key: keyway profile, length, shoulder position and brand. A blank that is close but not exact is how you end up with a copy that only works if you jiggle it.
- We cut the copy and deburr it so loose metal shavings do not end up inside your lock.
- We test the new key in the lock it is meant for, not just against the original. If it turns rough, we adjust or recut it.
- We hand over the keys and tell you plainly if the original is too worn to keep using. If it is, we recommend retiring it and working from the fresh copy.

Call (213) 577-1366Which keys can we duplicate?
Most keys that people bring us fall into a handful of categories. Some are routine, and some need a conversation first. Here is the range we cover under this service:
- House keys and spare house keys for front doors, back doors and side entries.
- Duplicate deadbolt keys, including keys for separate single-cylinder deadbolts that do not match the knob or handle set.
- Apartment key copies for tenants who need an extra for a partner, roommate or family member, with the right permission from the building.
- Office key duplication and commercial key duplication for suites, storerooms, file cabinets and back-of-house doors.
- Mailbox key duplication for individual boxes and cluster units, where the key and lock match is specific to the box.
- Gate, padlock and utility keys used on fences, side yards and storage.
- High security key duplication and restricted key duplication, which follow their own rules, covered in the next section.
Can high-security and restricted keys be copied?
Sometimes, but not on the same terms as a standard brass key. High-security keys often have unusual cuts, such as dimples, internal tracks or side milling, and they need the correct blank and the right cutting equipment. We confirm what you have in person before promising anything, because guessing wrong wastes your time and can ruin a good blank.
Restricted keys are a different case. The whole point of a restricted keyway is that duplicates are controlled. The system's owner usually has to authorize copies, often with a card, registration or sign-off from whoever manages the account. That protects you. If anyone with a hardware-store machine could copy a restricted key, the restriction would mean nothing. When we ask for authorization on one of these, we are not being difficult; we are protecting the integrity of the lock.
A stamp reading Do Not Duplicate is only a request stamped into metal. It does not stop a cutting machine. We still ask questions when we see one, and if a key belongs to an employer, a property manager or an HOA, we will want to know you have permission. If you are considering upgrading to a controlled system, our page on high-security locks explains how those systems work.
What affects the cost of duplicate keys?
We do not quote numbers on a web page, because the honest answer depends on the key in your hand. Here is what moves the cost up or down:
- Key type: a standard house key is the lighter-cost end of the range, while high-security and restricted keys involve specialty blanks and more careful work.
- Blank availability: some keyways use common blanks, and others take sourcing effort.
- How many copies you need: cutting several at once is usually the more economical route than coming back repeatedly.
- Condition of the original: a worn or damaged key may need extra work, or may not be a good master at all.
- Where the work happens: a counter job at our storefront differs from a mobile visit, which includes the technician's travel to you.
- Authorization: restricted systems may require paperwork before we can cut.

Call (213) 577-1366What does key duplication look like in Port Hueneme?
Port Hueneme is a compact coastal city, and nearly all of its exterior hardware sits within blocks of the ocean. The heavy marine layer, salt air and constant damp stiffen and corrode locks, gate latches and door closers noticeably faster than inland hardware. For key duplication, that has practical consequences: keys wear faster in sticky cylinders, and the same corroded lock that wears a key out is often the reason a copy does not turn smoothly.
Much of the housing is postwar single-family homes, and many of those entries have been refitted over the years with whatever deadbolt was convenient at the time. That means a household can be carrying two or three different key types for one front door. We sort that out during duplication. If you live in ZIP 93041 near the Hueneme Beach area and your front door needs two keys for two locks, we can copy both and test each against its own lock.
One local scenario comes up often near the beach: a corroded deadbolt or entry set that still works with a key everyone has stopped trusting. If the lock is stiff enough that a fresh copy will not turn it cleanly, cutting more keys is the wrong move. We will tell you honestly when a copy is worth making and when lock replacement makes more sense.
Condos, gated communities and Navy rentals: who needs copies here?
Port Hueneme has a large share of condos and townhomes, including the Surfside condominiums near the beach. Residents there often need spare keys for entry doors, mail and storage, and HOA rules sometimes decide who may authorize copies. If a key in your complex is restricted, we will ask for the right authorization rather than cutting it without it. If you manage the common areas and are thinking about a structure for who holds which keys, a master key system is worth a conversation.
Hueneme Bay is a gated 55+ community, and access hardware matters there. Residents sometimes need extra keys for gates, mail and doors, and a worn gate latch can make a perfectly good key seem faulty. If the gate itself is the issue, see our gate lock repair page. Keys near the Bubbling Springs greenbelt area follow the same salt-and-damp pattern as everywhere else in town.
Rental housing near Naval Base Ventura County serves Navy families, and turnovers create a steady need for spare keys: extra copies for a new household, replacements for ones that went missing during a move. Landlords and property managers with several units can read more at locksmith for landlords. Storefronts along Channel Islands Boulevard and Ventura Road have their own needs: employee keys, back-door keys and storeroom copies. For those, we cut commercial keys and tell you honestly if a key is on a restricted system.

Call (213) 577-1366Can you come to me for mobile key duplication?
Yes, in many cases. Our storefront is at 10740 Wilshire Blvd in Westwood, about 62 miles from Port Hueneme, so for most people here the practical route is one of our mobile vans rather than a trip to the counter. We do not promise arrival times, since they depend on where our technicians are, but you can call any hour and we will tell you what to expect.
Plain brass house and mailbox keys are usually straightforward to handle at your door. High-security and restricted keys are different. We may need to confirm the blank, the equipment and your authorization before anyone drives out, so we will ask about the key when you call. Sometimes the right answer is to bring us the key or arrange something different, and we would rather say that on the phone than waste your afternoon.
If you are not sure what you need, our mobile locksmith page explains how our van service works across the area.
When is a copy not the right answer?
Duplication is the right move when you have a good original, the lock works smoothly, and the only issue is you need more keys. It is the wrong move in a few situations, and we would rather tell you that than cut metal for the sake of it.
If you do not know who has copies of your keys, perhaps after a tenant moves out, a breakup, or a lost key ring, more copies only add to the problem. Lock rekeying changes the lock so the old keys stop working, usually at lower cost than replacing the hardware. If your lock is corroded, we will explain why a replacement may serve you better than another key.
Duplication also needs an original. If you have lost the only key, a copy is not possible. And car keys with chips are a separate matter altogether; this page covers house, office and mailbox keys. For a mailbox lock that is damaged beyond a key copy, see mailbox lock replacement.

Frequently asked questions
Can I get a spare house key made without bringing the original to your shop?
Often yes. Our mobile vans can handle many standard key jobs at your door in Port Hueneme. Call (213) 577-1366 and describe the key, and we will tell you whether it is a mobile job or whether it makes more sense to bring us the key.
What if my key is stamped Do Not Duplicate?
That stamp is a request, not a mechanical lock. We still ask about it. If the key belongs to an employer, landlord or HOA, we want to know you have permission. If the key is on a restricted system, authorization is usually required.
Can you copy a mailbox key?
In most cases, yes. Mailbox keys are small and specific to the lock, so we match the blank carefully. If the lock itself is damaged or the key is lost, a replacement lock may be the better route, and we will tell you which applies.
Do you duplicate high-security keys?
Sometimes. It depends on the key type, blank availability and whether the system is restricted. We confirm in person before committing, since guessing wrong can ruin a blank. If you have a card or authorization paperwork, have it ready.
I lost my only key. Can you just copy it?
No. A copy needs an original to cut from. If you have lost every key, the next step is usually rekeying or replacing the lock so you can have working keys again. We can talk through the options when you call.
Why does my new copy stick in the lock?
Near the coast, the cause is often the lock rather than the key. Salt air and damp can stiffen or corrode a cylinder. Sometimes a copy cut from a worn original is also to blame. We test the key in your lock to figure out which it is.
How much does it cost to copy a key?
It depends on key type, blank availability, how many copies you need, the condition of the original and whether the job is at our storefront or mobile. We explain what drives the cost on the phone rather than posting numbers online.
I manage rental units near the base. Can you cut multiple copies?
Yes. Landlords and property managers regularly need multiple copies at turnover. Tell us the key types and how many units are involved. If you are unsure who still holds old keys, we can also discuss rekeying.
Can you duplicate keys for a Surfside condo or the Hueneme Bay community?
We can cut standard keys for homes in either. If the key is restricted by an HOA or association, we will ask for the right authorization. For gate or common-area hardware, tell us what you have when you call.
