Why does key quality matter when you copy a key?
Most key trouble starts with a bad copy. A key is a measured object. The depth of every cut is held to a tiny tolerance, and the lock's pins or wafers only line up when each cut lands close to where it should. A copy that is a little off will often still turn the lock, but only with a jiggle, a lift, or a second try. Over time that sloppy fit wears the pins inside the cylinder, and sooner or later either the key or the lock gives up.
The other problem is copies of copies. Each time a key is cut from a worn key, the small errors stack. If your home dates from the 1940s or 1950s, as much of Paramount's housing does, there is a fair chance the keys in your kitchen drawer are several generations removed from whatever the builder handed over. We would rather start from the best original available, and we will tell you plainly when the key you hand us is too worn to copy well.
There is also a weather angle here. Paramount's damp winters can swell older wood doors, and a swollen door makes a deadbolt bind and feel like a key problem. Before we cut anything we check whether the key or the door is the real culprit, because a new copy will not fix a door that has simply swollen against its frame.
What kinds of keys do we duplicate?
Our key duplication work covers the keys people actually carry around Paramount, and a few they forget they own. Here is what comes through the door or the van most often.
- House key copies and spare house keys, including front door, back door, and side gate keys.
- Duplicate deadbolt keys, which often use a different keyway than the knob lock beside them.
- Apartment key copies for tenants and for owners with several units.
- Office key duplication and commercial key duplication for suites, back rooms, file cabinets, and storefronts.
- Mailbox key duplication for private and building-controlled mailbox locks.
- Padlock, gate, and security screen door keys, which people tend to lose first.
- High security key duplication and restricted key duplication, which follow a separate process described below.
How do we duplicate a key, step by step?
Copying a key is quick work for a trained hand, but it is not a vending machine process. Here is how we handle it every time.
- Look at the original. We check it for wear, bends, cracks, and a worn-down tip. A key that is already failing makes a poor template.
- Identify the keyway and blank. The brand and profile stamped on the key tell us which blank to use. A near match that slides into the lock is not the same as the correct blank.
- Check for restrictions. Some keys are patented or controlled and cannot be freely copied. If yours is one of them, we explain the authorization step before going further.
- Cut the copy. We cut it on a machine that is kept in good condition, then remove the burrs so the key does not drag metal shavings into your lock.
- Test it in the lock. A copy that looks right can still fail, so we try it in the actual cylinder when we can. If it is sticky, we fix the cut rather than tell you to give it time.
- Hand over keys that work. If the lock itself is the real problem, such as a worn cylinder or a misaligned bolt, we say so and offer repair or replacement. We do not leave you with a new key in a failing lock.

Call (213) 577-1366Can you copy a high security or restricted key?
Sometimes yes, but not at a hardware-store kiosk. High security keys use unusual profiles, sidebars, or dimples, and restricted keyways are controlled by the manufacturer so that only authorized people can order copies. That control is the entire point of the system. If you pay for a restricted keyway, you expect nobody to be able to copy your key on a whim.
If your key is marked with a brand name and a restricted-key notice, bring it to us or call. We will identify the system, tell you whether we can cut it on our own equipment or whether the manufacturer has to produce it, and say what proof of authorization is needed. That proof is usually a registered card, a signed request, or confirmation from the account holder. Timing depends on the manufacturer, so we will not promise a quick turnaround on a restricted order.
A word on 'Do Not Duplicate' stamps: they are a marking, not a lock. A stamped key on an ordinary keyway can be copied by a shop that chooses to, which is why a stamp alone is no security. If you want real control over who holds copies, the right move is a restricted system, and our high security locks page explains how those systems work.
Can you cut keys at your door with a mobile van?
For many standard keys, yes. Our mobile vans carry key blanks and cutting equipment, so we can copy common house, deadbolt, office, and padlock keys on site, and we can test the copy in your actual lock before we leave. That is handy when you cannot leave a property unattended, when you are managing several units, or when it is the middle of the night and you need an extra key now.
There are limits, and we would rather state them. Some keyways need a blank we do not carry in the van, and restricted or high security keys may have to be handled at the storefront or ordered through the manufacturer. If that is your situation, we will say so on the phone instead of sending a van that cannot finish the job. Our mobile locksmith page covers how our vans work more broadly.
Paramount is about 23 miles from our Westwood storefront, and we serve it as part of the 140 cities we cover across Los Angeles and Ventura counties. Describe the key and the lock when you call, and we will tell you whether a van visit or a drop-off makes more sense.

Call (213) 577-1366What affects the cost of key duplication in Paramount?
We do not quote numbers on a web page, because the honest answer depends on the key. Here is what actually moves the cost up or down.
- Key type. A basic single-sided house key is the lighter-cost end of the range. Dimple keys, sidebar keys, and keys with tamper-resistant features take more time, more specialized blanks, or both.
- Restricted keyways. When the manufacturer has to produce the copy and verify authorization, the process involves more steps and usually costs more than a standard cut.
- Quantity. Several copies cut in one visit are usually the more economical route than coming back repeatedly for single keys.
- Condition of the original. A worn or damaged key can take extra effort to copy well, and sometimes the better option is to work from the lock itself.
- Where the work happens. Bringing the key to the storefront is usually the more economical route. A mobile visit adds travel and van time, which is worth it when you need the key on site or after hours.
- Time of day. Our phones are answered around the clock, and after-hours visits are priced differently from daytime ones.
Key duplication around Paramount: houses, apartments, and shops
Paramount was formed in 1948 from the dairy towns of Hynes and Clearwater, and the housing in those historic districts is mostly small 1940s and 1950s single-family homes. Those houses have often had their keys passed around for decades, so a fresh set of spares, or a spare house key cut from a clean original, is a common request in the 90723 ZIP code. If you are not sure who holds old copies, a lock rekey makes every older key useless, and then we cut new copies for the people who should have them.
The city also has a high renter share, with many 1960s-1980s apartment complexes along the Paramount Boulevard and Downey Avenue corridors. Apartment key copy requests there are usually simple: a tenant needs one more key for a roommate or a family member. We cut those when you can show you are entitled to the key, and we may check with the property manager if the key is on a controlled system. Mailbox key duplication comes up in the same buildings, and if the lock itself has to change rather than just the key, our mailbox lock replacement service handles that. If you are locked out of an apartment rather than short a key, the apartment lockout page is the better starting point.
Security screen doors are common on both houses and apartments in Paramount, and they often carry their own key, separate from the main door. People tend to lose that one first, so mention it if you are ordering spares. Mobile home parks around the city have their own mix of hardware, and duplicate keys for those locks usually take a quick look at the key first. Along Alondra Boulevard, Rosecrans Avenue, and the Somerset Boulevard area, business owners ask for office and storefront copies, and we can cut those for the staff who need them.

Call (213) 577-1366Why call Wilshire Lock & Key for key copies?
We have been in business since 1987, and key work is something we have done every working day since. We run a storefront at 10740 Wilshire Blvd in Westwood plus mobile service vans, so you can drop a key in or have us come out. When you call (213) 577-1366, you reach our company rather than a call center passing your job to whoever is free. We answer the phone 24 hours a day, seven days a week, all year.
David, our owner and lead technician, oversees the work. That matters most when a job is not routine: an odd keyway, a worn original, or a restricted key that needs paperwork. We will tell you when a copy is not the right answer. Sometimes the better fix is a rekey, a repair, or a new cylinder.
One more thing worth knowing whoever you hire: California requires locksmith companies to hold a BSIS LCO license, and you are entitled to ask any locksmith for it. A reputable company will not be bothered by the question.
When a copy is not the right fix
Sometimes the real problem is bigger than one more key. If you have lost track of who holds keys, or a former tenant, roommate, or employee still has one, rekeying or changing the lock is better than cutting more copies. If you manage several doors, a master key system lets one key open many locks while keeping each lock separate. Landlords handling turnover across many units can look at our locksmith for landlords page.
Car keys are a different job. Many modern vehicle keys contain a chip that has to be programmed to the car, and a plain cut will not start the engine. We confirm what a particular vehicle needs by VIN or in person rather than guessing, and some cases are dealer-only. Our car key replacement page explains how we approach those requests.
Frequently asked questions
Do I need to bring the original key for key duplication in Paramount?
For the best result, yes. A clean, undamaged original gives the most accurate copy. If your only key is badly worn, tell us when you call. We can often work from the lock itself or suggest a rekey if the lock no longer has a usable key.
Can you copy a key that says 'Do Not Duplicate'?
It depends on the keyway. A stamp on an ordinary key is just a marking and does not stop a copy. A truly restricted key is a different story: it is controlled by the manufacturer, and we will ask for proof of authorization before ordering or cutting it.
Can you cut a key without the original?
Sometimes. If the lock is in front of us, we can often cut a key to fit it. If the lock is unavailable and no key exists, the practical route is usually a rekey or a new cylinder, and we will tell you which makes more sense for your door.
Can you make an apartment key copy for me?
Usually yes, if the key is on an ordinary keyway and you are entitled to it. Some apartment buildings use controlled keys that only the property manager can authorize. If yours is one of those, we will say so up front.
Do you duplicate mailbox keys?
Yes, for private and building mailbox locks on standard keyways. Postal service locks are controlled by the postal service, so we may point you to the post office for those. If the lock itself is damaged, replacement is the better fix than another copy.
Will you come to me for key duplication, or do I have to bring the key in?
Both are options. Our storefront in Westwood takes drop-offs, and our mobile vans can cut many standard keys on site. Restricted or unusual keys may have to be done at the shop or ordered from the manufacturer, and we will say so when you call.
How much does it cost to copy a key?
It depends on the key type, whether it is restricted, how many copies you need, the condition of the original, and whether we come to you or you come to us. A standard house key is on the lighter-cost end. Call (213) 577-1366 and describe the key for a clearer picture.
Can you copy a car key?
A plain metal car key can be cut, but many newer keys contain a chip that must be programmed to the vehicle. We confirm what a particular car needs by VIN or in person, and some vehicles are dealer-only. We will be upfront about which case yours is.
Can you cut a duplicate deadbolt key?
Yes. Deadbolts often use a different keyway than the knob lock on the same door, so we match the blank to the actual lock. We test the copy in the cylinder when we can, so you are not left with a key that only almost works.
