Why does a spare house key in Tarzana deserve a careful copy?
A key copy looks like the simplest job in the trade, which is exactly why so many bad ones are out there. A key is a small piece of metal that has to match the pin positions in a lock within a very tight tolerance. A copy that is a hair off will still slide in and still turn on a good day. Then it starts to stick, bind, or wear the pins inside your lock a few months later. It usually fails at the worst moment, at night, with your hands full.
Tarzana households lean on spare keys more than most. A ranch home north of Ventura Boulevard can easily have a front door key, a separate deadbolt key, a side gate key, and a garage entry key. Condo and apartment residents carry a building key, a unit key, and a mailbox key. Estate and equestrian properties add gate padlocks and outbuilding keys on top of that. When one of those keys goes missing or wears down, a clean duplicate is the fastest way back to normal.
This page explains what we copy, how we do it, what changes the cost, and when a copy is not the right answer. If you would rather just talk it through, call (213) 577-1366. A person answers at any hour.
How do we duplicate a key, step by step?
Whether you walk into our storefront at 10740 Wilshire Blvd in Westwood or meet one of our mobile vans, the process is the same. We do not treat a copy as a quick pass through a machine. Here is what actually happens:
- We look at your original key first. We check it for wear, bends, and damage, and we identify the keyway and the type of blank it needs. If the key is badly worn, we tell you, because a copy of a worn key inherits that wear.
- We match the blank. Blanks can look nearly identical and still not be interchangeable. The brand, keyway, and length all have to line up with your lock.
- We cut the key on a calibrated machine, tracing your original or cutting by code when that is the better method for the key in your hand.
- We deburr and clean the new key. Leftover metal burrs drag debris into the lock and make the key feel rough, so this step matters more than people expect.
- We test the copy in the lock whenever the lock is in front of us, such as when we are at your door. If you brought only the key, we test the action as best we can and tell you what to watch for.
- If the key sticks or turns stiffly, we adjust or recut it rather than hand it over and hope. A new key should turn about as smoothly as the original did when it was new.

Call (213) 577-1366Which keys can we copy, and which need extra steps?
Most keys are routine. Some come with conditions, and we would rather explain those at the start than surprise you at the counter.
- House keys and duplicate deadbolt keys: Standard residential keys are the everyday job. Many homes use one key for the knob and a different one for the deadbolt, so bring every key you want copied. If you want a single key to run every lock on the house, that is a rekeying job rather than a copy.
- Apartment key copy: Many buildings stamp keys with a do-not-duplicate mark. We use judgment here. We may ask whether you are the tenant or owner, and if a property manager's policy applies we will say so honestly instead of cutting a key that gets you in trouble with your lease.
- Office key duplication and commercial key duplication: We copy keys for staff, suites, and storage rooms. If you are handing out more than a few keys and need to control who can open what, a master key system is a better structure than a pile of copies.
- Mailbox key duplication: Private mailbox locks are usually straightforward. Postal-controlled locks are a different story, and in many cases they are handled through the postal service rather than a locksmith. If your lock is the problem and not the key, see our mailbox lock replacement service.
- High security key duplication: Keys for higher-security cylinders often use tighter tolerances and special blanks. Many can be copied with the right blank and equipment. If you are considering an upgrade, our overview of high-security locks explains the tradeoffs.
- Restricted key duplication: Some keyways are controlled by the manufacturer. Copies require proof of authorization, and without it we cannot cut them. We will tell you what the lock maker's process is so you are not left guessing.
- Padlock, gate, and cabinet keys: These are usually simple, though the quality of the key matters. A weathered padlock key is a good candidate for a fresh cut from the original.
Can you duplicate keys at my door? Mobile key duplication
Yes, in most cases. Our mobile vans carry cutting equipment and a range of common blanks, so many standard house, office, and gate keys can be copied where you are. That is handy if you are caring for a family member, running a business you cannot leave, or simply do not want to drive across the Valley with your only key in your pocket. Details are on our mobile locksmith page.
The honest limit is blanks. If your key needs a specialty or restricted blank that is not on the van, we say so before you wait for us, and the job may come back to the storefront instead.
One more distinction matters. Duplication assumes you still have a working key to copy from. If you are standing outside with no key at all, that is a house lockout, and the first job is getting you in. A new set of keys can follow once you are inside.

Call (213) 577-1366What affects the cost of duplicating a key?
We do not quote numbers on a web page, because the same request can mean very different work. What moves the cost is predictable, though:
- The type of key. A plain residential key is a lighter job than a high-security or restricted key with a specialty blank.
- Blank availability. Common blanks are on the shelf. Unusual ones may have to be sourced.
- How many copies you need. Cutting several keys in one visit is usually the more economical route than coming back repeatedly.
- Condition of the original. A clean original makes a clean copy. A worn key may need extra care or a different cutting method.
- Authorization steps. Restricted systems require verification before anything is cut.
- Where the work happens. Bringing keys to the storefront is usually the more economical route. Mobile service adds travel, and Tarzana is roughly 14 miles from our base.
- Time of day. Late-night and holiday calls cost more than a weekday visit, since a technician is rolling out for you.
- Whether anything else is needed. If the lock itself is damaged, a copy will not fix that. We will tell you before extra work is added.
What does key duplication look like across Tarzana's neighborhoods?
Tarzana covers a wide range of homes, and the keys that come with them vary just as much. Here is how duplication tends to play out in different parts of the community, all within ZIP code 91356.
In Melody Acres, the equestrian-zoned lots often have a driveway gate, a paddock gate, and a barn or tack room, each with its own padlock or key. Those exterior keys live outside, in sun, dust, and wind, and they wear faster than a key that only sees an interior front door. If a paddock gate key is starting to feel loose in the lock, copy it from the original now, before it gets worn down further. If the gate hardware itself is the problem, our gate lock repair service covers that.
In Mulholland Park and Braemar Estates, the guard-gated, estate-style homes usually have several entry points, including front doors, service doors, and pool or guest house locks. Spare keys for those are best cut from originals and kept in more than one safe place. If a gate runs on cards or remotes rather than a cut key, that is access-control work and not key cutting. We will point you to the right service.
Along the Ventura Boulevard corridor, condo and apartment residents typically carry a unit key, a building or common-area key, and a mailbox key. We can cut copies of the ones that are properly yours to copy, and we will be straight about any building policy that applies.
Around the Tarzana medical district near Providence Cedars-Sinai Tarzana Medical Center, small offices and suites often need extra keys for staff turnover or after-hours access. Our commercial locksmith team handles office key duplication and can advise on whether a single copy or a more structured key plan makes sense.
Storefronts in the Tarzana Safari Walk business district on Ventura Boulevard have a similar need. Front doors, back doors, and stock rooms all need working keys for the people who open and close. And in the North Tarzana flats along Victory and Vanowen, the postwar ranch tracts tend to have decades-old keys that have been copied from copies, which is exactly where a fresh cut from a clean original pays off.

Call (213) 577-1366Why call Wilshire Lock & Key for key duplication?
We have been in business since 1987, and key cutting is one of the oldest parts of the trade. David, the owner and lead technician, oversees the work. We are one company, with a real storefront at 10740 Wilshire Blvd and our own mobile vans. That means no dispatch middleman who has never held your key, and no handoff to a stranger you cannot reach later.
We serve 140 cities across Los Angeles and Ventura counties, so Tarzana is one of many places we work regularly. Our phone line at (213) 577-1366 is answered 24 hours a day, 7 days a week, year-round. Most key duplication is not an emergency, but the ones that are, like a tenant who needs a copy before a family member arrives tonight, deserve a real person on the line.
One more thing to know. California requires locksmith companies to hold a BSIS LCO license. Whoever you hire for key work, ask for their license number. It is a reasonable question and a good company will not mind it.
When is a copy not the right fix?
Sometimes a duplicate is the wrong tool, and we would rather tell you than sell you a key you do not need.
If you have lost a key and do not know who might have found it, copying your remaining key leaves the old one in circulation. Rekeying the lock makes the lost key useless. If a key has snapped off in the lock, that is a broken key extraction job, and cutting a new key comes after the lock is clear. If you are managing several tenants or staff and keys keep multiplying, a master key system or different hardware may serve you better than one more copy.
And if your original key is so worn that it barely works, the lock may be worn too. A copy from a bad key often feels bad in a bad lock. In that case we will check the lock and tell you whether duplication will help or whether the lock needs attention first.
Frequently asked questions
How long does it take to copy a key?
For a standard house key it is usually a short stop, not a long wait. Specialty keys, restricted systems, and anything that needs authorization checks take longer. If we do not carry the right blank, we will tell you when you call so you do not make the trip for nothing.
Can you copy a key marked 'Do Not Duplicate'?
That stamp is a request from the building or manufacturer, not a law, but we take it seriously. We may ask whether you are authorized to have a copy, and if a property manager's or system owner's policy applies we will say so. Many apartment buildings do require permission before extra keys are made.
Can you copy a high-security or restricted key?
Often yes for high-security keys, provided we have the right blank and equipment. Restricted keys are different, because the manufacturer controls who can order copies. We need proof of authorization before cutting, and we will explain the process if we cannot do it on the spot.
Can you copy my mailbox key in Tarzana?
Private mailbox locks are usually simple to copy. Postal-controlled locks are often handled through the postal service instead, so we will tell you honestly which kind you have. If the lock itself is broken or missing, replacement is a separate service.
Do you come to me for key duplication?
Yes, our mobile vans can copy many common keys at your home or office in Tarzana. If your key needs a specialty blank that is not on the van, we will tell you before you wait. Bringing keys to our Westwood storefront is often the more economical route when you are not in a rush.
What if my key is worn or is a copy of a copy?
Each generation of copy passes along the previous key's wear, so a copy of a copy can drift out of tolerance. We inspect the key first and tell you whether it is good enough to copy from. If it is not, we may suggest a different cutting method or look at the lock itself.
Do I need to bring the lock with me?
Usually not. The key is what we copy from. Bringing every key from a door, including both the knob and deadbolt keys, helps us match your setup. If the key has been sticking, mention it, because that can point to a lock problem as well.
Should I make a copy or rekey after losing a key?
If you lost a key and do not know where it went, rekeying the lock is the safer move, because it makes the lost key stop working. A copy is better when you simply want a spare and nothing has gone missing. We can explain both when you call.
Can you copy a car key too?
A basic metal-only cut is one thing, but many modern car keys contain a chip that must be programmed to the vehicle, and that is a separate automotive service. Whether a given key can be copied depends on the vehicle, so we confirm by VIN or in person before promising anything.
What should I ask a locksmith before they cut my keys?
Ask for their California BSIS LCO license number, since the state requires locksmith companies to hold one. Also ask whether they are an actual local company or a dispatch service, and how the price is determined. A clear answer to each is a good sign.
