What does key duplication actually involve?
Key duplication is the simple-sounding job of making a working copy of a key you already have. It is also the job where small mistakes show up later, usually at the worst moment: a key that sticks, turns only if you jiggle it, or works for a month and then stops. A good copy is not just a key that looks right. It is a key whose cuts match the original to a very tight tolerance, on a blank that fits the lock's keyway, finished cleanly enough that it will not chew up the pins inside your cylinder.
At Wilshire Lock & Key we cut house keys, spare deadbolt keys, apartment keys, office keys, and mailbox keys for Toluca Lake customers, and we handle the higher-security and restricted keys that a hardware-store kiosk will turn away. This page covers that work. If what you really need is a lock changed, a lockout opened, or a key pulled out of a cylinder, we will point you to the right service instead of cutting a key that will not solve the problem.
Why a bad copy causes more trouble than no copy
Most people only think about duplicates when they are handing a spare to a house sitter, a dog walker, or a family member. By then the copy is already cut, and nobody tests it against the lock until it is needed. A poorly cut key can fail in several ways, and each one has a cause we can name.
The most common is copy drift. If a key is copied from a copy, then that copy is copied again, each generation adds a little error. A cut that is off by a hair on its own might still turn a worn lock, but stack two or three of those and the key stops lifting the pins to the right height. The second is the wrong blank. Keys that look nearly identical can have different keyway profiles, and a blank that is slightly off will enter the lock but never seat properly. The third is rough finishing. Burrs left on a fresh cut catch inside the cylinder and wear it faster than you would expect.
- Copy-of-a-copy drift: small errors compound with each generation.
- Wrong blank: it enters the lock but does not seat or turn cleanly.
- Leftover burrs: they scrape the pins and shorten the cylinder's life.
- Worn originals: a key that is already rounded off passes its wear on to the duplicate.

Call (213) 577-1366How we duplicate a key, step by step
The process is straightforward, and we do it the same careful way whether it is one spare or a dozen. We would rather take an extra minute at the bench than have you come back because a key binds.
- We look at your original key, check its condition, and identify the keyway and brand. If the key is worn, we say so and talk through whether to cut from it or from a better source.
- We match it to the correct blank. This is the step that most quick copy counters rush, and it is where fit problems begin.
- We cut the duplicate to the original's depths and spacing, then remove burrs and smooth the edges.
- We test the new key against the original, and where we have the lock in front of us we test it in the lock itself, turning it several times in both directions.
- We tell you plainly if the original is worn enough that a fresh copy will not behave much better, and what your options are.
Which keys can we copy?
Most keys are routine. Some need extra care, and a few require paperwork before anyone should cut them. Here is how we sort them.
- House and spare house keys: standard residential keys for entry doors, including the keys for a duplicate deadbolt key, which is often a different blank from the knob lock beside it.
- Apartment key copies: unit keys and building keys, with the understanding that some buildings control who may copy common-area keys.
- Office and commercial key duplication: shop, suite, and back-door keys, including the keys used on a master key system, which we handle with more caution than single-door keys.
- Mailbox key duplication: small, easy to lose, and usually quick to copy. If the mailbox lock itself is damaged, a copy will not help and mailbox lock replacement is the fix.
- High security key duplication: keys with more complex cuts, dimples, or side-milled profiles that need the right machine and the right blank.
- Restricted key duplication: keys on patented or controlled keyways, which we cut only for someone who can show they are authorized.
What about restricted and 'Do Not Duplicate' keys?
A stamp reading 'Do Not Duplicate' is a request, not a lock. Plenty of ordinary keys carry it, and a stamp alone does not change how a key is copied. We use judgment: if you are the owner or manager and the key is a normal keyway, we will talk it through with you and usually can help.
True restricted systems are different. These use patented keyways and blanks that are supposed to be available only through the manufacturer or an authorized channel. Their whole purpose is to keep copies under control. For those, we ask for proof that you are authorized, which may mean an authorization card, a record held by the property owner, or documentation from the building. If we cannot confirm it, we will not cut the key, and we will say why. That is not us being difficult. It is what protects the next person who relies on that lock.
If you want a system where you control who can copy your keys in the future, that is a conversation about high-security locks, and we are glad to walk through it.

Call (213) 577-1366What affects the cost of copying a key?
We do not quote numbers on a web page because the work varies, but we can tell you exactly what moves the cost, so nothing surprises you. A plain brass house key on a common blank sits at the lighter-cost end. From there, a few things change the picture.
Key type is the biggest factor. Standard keys are quick. High-security and restricted keys use costlier blanks and more specialized cutting, and some need verification steps. The quantity matters too, since a handful of keys for a household or a small office is more efficient than one at a time. The condition of the original counts as well: a worn key may need extra attention or a different approach. Finally, location matters. Copying at our Westwood storefront is the usually more economical route. If you need a technician and mobile van to come to you, there is a service component for that travel.
We will tell you what applies to your keys before we start cutting, not after.
Why have Wilshire Lock & Key cut your keys?
We have been in business since 1987, and key work is the foundation of what a locksmith does. Everything else grows out of knowing keys: how they wear, how they bind, and how a lock tells you something is wrong.
A few honest differences are worth knowing about.
- One company, no dispatch middlemen: the person who answers the phone works for the same company that sends the van.
- A real storefront at 10740 Wilshire Blvd in Westwood, plus mobile service vans, so you can come to us or have us come to you.
- David, the owner and lead technician, oversees the work, which means standards do not change depending on who is on the schedule.
- The phone at (213) 577-1366 is answered 24 hours a day, 7 days a week, year-round, so you can arrange a copy or ask a question any time.
- We say so when a copy is the wrong answer. Sometimes a rekey, a repair, or a replacement will serve you better than another key.
- California requires locksmith companies to hold a BSIS LCO license, and you should ask any locksmith, including us, to see it before work begins.
Key duplication around Toluca Lake: what we see here
Toluca Lake is a small neighborhood, ZIP code 91602, with a mix that makes key work interesting. The older estates, many dating from the 1920s and 1930s, sit behind gates and privacy hedges. Those homes often carry a mix of vintage hardware and modern retrofit security, so one household might hold an old mortise key, a newer deadbolt key, a gate key, and a side-door key that all look a little different. Copying them well means identifying each one correctly rather than treating all keys as the same.
In the Lake enclave, where the private shoreline homes are part of a homeowner association, spare keys are a practical matter of who needs access: family, house staff, a property manager. For homes near Lakeside Golf Club, gates and estate locks add more keys to the ring, and when a gate lock is the problem rather than the key, gate lock repair is the next step. We can come out to you with a mobile van, and when you need the fresh copy tested in the actual lock, that is the better route than a counter.
Along Riverside Drive, the village commercial district has shops and restaurants where keys get copied for staff turnover, opening and closing routines, and back doors. The low-rise condos and apartments on Riverside Drive and the Cahuenga edge add unit keys, mailbox keys, and building keys. Residents of nearby areas such as West Toluca Lake, Toluca Woods, and Toluca Terrace tend to need the same things: a spare for the front door, one for the deadbolt, one for the mailbox.
If you have a 1920s or 1930s house still running on its original hardware, a copy is often a good short-term answer, but we will tell you honestly if the old cylinder is worn enough that a new key will only work as well as the tired lock allows. In that situation a rekey may suit you better, and we can explain the difference.

Call (213) 577-1366Mobile key duplication when you cannot come to us
Our storefront is in Westwood, about 15 miles from Toluca Lake, so not everyone will want to make the trip for a spare key. That is what the mobile vans are for. A mobile locksmith visit lets us cut keys on site, test them in your door right there, and handle other small adjustments while we are at the property.
Mobile service is especially useful for an estate owner who does not want to hand an original key to someone else, a property manager who needs several copies for a unit, or a business that cannot leave the shop unattended. Call (213) 577-1366, tell us what keys you have and how many copies you need, and we will tell you whether bringing them to us or having us come to you makes more sense for your case.
When a copy is not the right fix
Sometimes people call for a duplicate when the real issue is something else, and it saves you money and effort to sort that out first.
If you have lost every key and do not have one to copy, you are not looking at duplication, you are looking at access and a new key. A house lockout call comes first, and we can then make you a working key. If you do not know who else holds a copy, such as a former tenant, a contractor, or an ex-roommate, a spare does not solve that. Having the lock rekeyed makes the old keys useless without replacing the hardware. And if a commercial space has several staff keys floating around, a master key system is a better way to organize who can open what than a growing pile of copies.
Car keys with chips are also a different job from a house key copy. For those we confirm details by VIN and in person rather than guessing, and some vehicles may only be handled through a dealer. We will say so honestly if that applies to yours.
Frequently asked questions
How many spare house keys should I have made?
Most households do well with one spare for a trusted person and one stored securely at home. More copies mean more keys to track. If you are handing keys to several people, such as staff or tenants, consider rekeying so you know who holds a working key.
Can you copy a worn or damaged key?
Often, yes, but a worn key passes its wear to the copy. We look at the original first and tell you whether it is safe to cut from, or whether a better approach exists. If the key is bent or cracked, we will advise against copying it as is.
Do you copy keys stamped 'Do Not Duplicate'?
A stamp by itself is not a legal lock on copying. For a standard keyway, if you are the owner or manager, we will talk it through. For genuinely restricted keyways, we need proof of authorization before cutting anything.
Can you make a duplicate deadbolt key?
Yes. Deadbolt keys often use a different blank from the knob lock beside them, so we identify the right keyway and test the copy in the lock whenever we are on site.
Can you copy a mailbox key?
Yes, mailbox keys are usually quick to cut. If the mailbox lock is jammed or broken, though, a new key will not fix it, and the lock itself would need to be replaced.
Do you copy high security or restricted keys in Toluca Lake?
We handle high security key duplication with the correct blanks and machines. Restricted keys are cut only when you can show you are authorized. If we cannot verify that, we will explain why we cannot proceed.
Can you come to my Toluca Lake home to make the keys?
Yes. Our mobile vans can cut and test keys at your property. Call (213) 577-1366 with the type and number of keys, and we will confirm the best way to handle it.
Are copies from you as reliable as the original key?
A well-cut copy on the right blank should work smoothly. Reliability depends on the condition of your original and your lock. If the lock itself is worn, even a perfect key may stick, and we will tell you if that is the case.
Is a duplicate key a security risk?
Every copy is another key that can open your door. That is fine when you know where each one is. If you are unsure who holds a copy, rekeying is the safer move, since it makes all older keys stop working.
