Why do Gardena households and businesses end up needing duplicate keys?
Nearly every key duplication call starts with the same sentence: this is the only key I have. One key hangs on a hook by the door, or one key rides on a ring that goes everywhere, and there is no plan for the day it gets lost, left in a jacket, or locked inside a car. A spare house key cut from a good original takes a few minutes of attention. A lockout takes an evening.
Gardena makes the one-key problem easy to fall into. The city is largely built out with 1940s and 1950s single-family tracts, garden apartments, and condo complexes, and it has a high share of small multi-unit rental properties. Households change, tenants come and go, and older homes often carry more than one lock to keep track of: a deadbolt, a knob lock, and sometimes a separate lock on a security door. Each of those can mean another key to copy.
Businesses hit the same wall from the other side. A new employee needs access, an owner wants a backup stored off-site, or a manager has lost the only copy of the back-door key. Here is who we usually cut for:
- A family member, roommate, or caregiver who needs regular access to a house or apartment
- A spare house key kept with a trusted neighbor or stored safely away from home
- A duplicate deadbolt key, since the deadbolt often takes a different key than the knob lock
- Office keys for staff, cleaners, or a second location
- Mailbox keys for a household member or a small business
- A worn key that still works but is on its way out
How does key duplication work with us, step by step?
A good copy depends on three things: a clean look at the original key, the right blank, and a cut that is checked before it leaves our hands. Here is how we run it.
- Call (213) 577-1366. The line is answered 24 hours a day, every day of the year. Tell us what the key opens, any name or number stamped on the bow, and how many copies you want.
- We identify the key. Keyway, blank type, and wear all matter. If the key looks like a high-security or restricted design, we say so right away and explain what that changes.
- We pick where it gets cut. Many keys can be cut at our storefront at 10740 Wilshire Blvd in Westwood. If you would rather not travel, ask about mobile key duplication through our mobile locksmith service. We will tell you honestly whether your particular key suits a visit at your door.
- We cut from the best key you have. An original is always a better source than a copy of a copy, because every generation passes along small errors in the cut.
- We finish and test. After cutting, the edges are cleaned so burrs do not chew up your lock, and when we are on site we try the new key in the lock it is meant for. If a copy cut at the storefront drags in your lock, bring it back and we will look at it.
- You leave with simple advice. Keep one copy away from home, and mark which key goes to which lock so you are not guessing later.

Call (213) 577-1366Which keys can we copy, and which need extra steps?
Most household keys are simple to copy. Standard house keys for knob locks and deadbolts, office door keys, and small cabinet or mailbox keys are routine work. The details change when a key is built to resist copying.
Condition matters too. A key worn smooth, bent, or cracked is a poor source, because the copy inherits every flaw. If your only key is badly worn, tell us when you call. We may suggest checking whether the lock itself needs attention before cutting more keys to fit it. And if a key has already snapped off inside a lock, that is a different job, covered under broken key extraction.
- Standard keys: common pin-tumbler house, deadbolt, and office keys. Usually straightforward once we see the key.
- High-security keys: unusual profiles, such as dimple or sidewinder styles, need matching blanks and the right cutting equipment. Our page on high-security locks explains what makes these systems different. We confirm by looking at the key in person before promising a same-day copy.
- Restricted keys: these use protected keyways, and the manufacturer controls who can order copies. Expect to show authorization. Some can only be ordered through the manufacturer or an authorized dealer. If that is your situation, we will say so plainly rather than cut something that may not work.
- Keys stamped Do Not Duplicate: that stamp is a request, not a lock. We will ask about the key's source and who authorized the copy, especially for commercial and property keys.
- Vehicle keys with electronics: these are a different job from a house key. See car key replacement for those.
What affects the cost of key duplication in Gardena?
We do not put numbers on a web page, because the honest answer depends on the key in your hand. These are the things that move the cost up or down:
- Key type: a standard house key is the simplest. High-security and restricted keys involve special blanks, tighter cutting, and sometimes an authorization step.
- Number of copies: one spare and a dozen for a staff are not the same job.
- Condition of the original: a clean original is quick. A worn one may need extra care or a different approach.
- Where it is cut: bringing the key to the storefront is usually the more economical route. Having us come to you adds the convenience of a mobile visit, and travel is part of that picture.
- Time of day: the phone is answered around the clock, but an after-hours visit is priced differently from a daytime one.
- Whether anything else is wrong: if the lock is failing, a copy will not fix that, and we will tell you before you pay for keys that will not help.

Call (213) 577-1366How do apartment, office, mailbox, and deadbolt keys differ?
Apartment key copy: check your lease before you copy anything. Many leases require the landlord's permission to add keys, and some building keys are restricted for exactly that reason. If you manage rentals, our page on a locksmith for landlords covers key control across several units.
Office and commercial key duplication: this is usually about control as much as convenience. Keep a record of who holds which key. If an office has many doors and many people, a master key system can replace a heavy ring of keys with an organized plan. Commercial keys on restricted systems follow the authorization rules above.
Mailbox key duplication: mailbox keys are small and easy to lose. If you have the key, we can copy it. If you have no key at all, or the box is in a shared cluster the property manages, the fix is often a new lock, covered under mailbox lock replacement. Ask your property manager who is responsible for the lock before you arrange anything.
Duplicate deadbolt key: bring the deadbolt key itself, not just the knob-lock key. The two are frequently different, particularly in older homes where locks were swapped out over the years.
What does key duplication look like around Gardena?
In Hollypark, Moneta, and Strawberry Park, the typical job is a spare for a single-family home from the tract era: one for a family member, one for a trusted neighbor, and often a separate key for a security door. Security doors and window bars are common on older housing here, and they tend to add keys to the ring. Gather every key before you call and tell us which lock each belongs to, so one visit covers them all.
Along the Western Avenue corridor, apartment complexes and mailbox keys are the pattern. Tenants share entry doors and mailboxes, and a lost mailbox key is a regular headache. Whether you are in 90247, 90248, or 90249, the first question for an apartment key is the same: who controls it? If the building does, the property manager should be part of the conversation.
In the Gardena Boulevard old downtown strip, storefront keys are the common request: an owner wants a second front-door key for a manager, or a spare kept off-site. Along Rosecrans and Artesia, where light-industrial buildings mix with homes, warehouse and roll-up door keys get copied for crews and supervisors. For any business with staff coming and going, including those near the Redondo Beach Boulevard casino corridor, a written record of every copy cut is worth the five minutes it takes.
Gardena sits on the inland coastal plain. The marine layer brings overcast and damp mornings, but there is minimal direct salt exposure, so you are looking at ordinary wear rather than coastal corrosion. Doors can swell slightly on damp mornings, and people respond by forcing the key. That wears keys faster than you would expect. If your key has started to stick or needs jiggling, copy it from the original now, before the wear gets cut into every spare.
Gardena is about 17 miles from our Westwood storefront, and we serve it with mobile service vans. Call (213) 577-1366 and we will say whether a visit or a drop-off suits your key better.

Call (213) 577-1366When is a copy the wrong fix?
A duplicate gives another person the same access you have. That is the wrong move when you do not know where the existing keys are: a lost or stolen set, a previous tenant, a former roommate or partner, an employee who has left. Cutting more keys to a lock that unknown people can open only adds to the problem.
In those cases, rekeying the lock is usually the better route. It changes the lock so the old keys stop working, and you keep the hardware you already have. We are happy to talk it through on the phone, and if a copy is all you need, we will say that too.

Frequently asked questions
Can I get a spare house key made in Gardena without bringing the original to the shop?
Call (213) 577-1366 first. For many standard keys we can discuss mobile key duplication and tell you whether your key suits a visit at your door. For some keys, especially high-security ones, we need to see the key in person before we promise anything.
How long does it take to duplicate a key?
For a standard house key it is a short job once we have the key in hand. High-security and restricted keys take longer because of special blanks and authorization steps. We will tell you what to expect on the phone, based on the key you describe.
Can you copy a key stamped Do Not Duplicate?
That stamp is a request from the manufacturer or owner, not a mechanical block. We will ask about the key's source and who authorized the copy. If it belongs to a restricted system or a property you do not control, we may need authorization or may send you back to the owner.
Do you duplicate high-security and restricted keys?
Sometimes. High-security keys need matching blanks and cutting equipment, and restricted keys often require authorization through the manufacturer or an authorized dealer. We confirm by looking at the key in person, and where a key is dealer-only, we say so honestly.
Can I copy my apartment key?
Check your lease first. Many leases require the landlord's permission to add keys, and some building keys are restricted. If your property manager approves, we can usually handle a standard apartment key quickly. Ask who controls the lock before you start.
Can you make a mailbox key if I have lost the original?
Without the original, a copy is not possible in the usual sense. The lock may need to be changed instead, and in shared mailbox clusters the property often controls that. Ask your property manager, and we can help with the lock side.
Can you cut keys for a whole staff or several offices?
Yes. Tell us how many keys and which doors, and we will plan the order. Keep a written record of who holds each key. If your key ring keeps growing, ask about a master key system.
What is the difference between a duplicate deadbolt key and a house key copy?
The deadbolt and knob lock on the same door often take different keys, especially in older homes where hardware was replaced over time. Bring both keys if you are unsure, and we will copy the right one.
Is a copy as good as the original key?
A well-cut copy from a clean original should work smoothly. A copy of a copy, or a copy from a worn key, carries over small errors. That is why we cut from the best source key available and try the new key when we are on site.
Do you answer the phone at night for key requests?
Yes. Our line at (213) 577-1366 is answered 24 hours a day, 7 days a week, year-round. For a spare key, a daytime visit is usually the more economical route, but we are there if the situation cannot wait.
