Key Duplication in Whittier, CA

What does key duplication actually involve?

A key copy sounds like the simplest job in the trade, and for a plain brass house key it often is. But a good copy is not just a piece of metal that looks right. It has to match the depth of every cut on the original and the spacing between them, to a tolerance of a few thousandths of an inch, and it has to match the keyway profile so it slides into the lock without catching. A copy that is slightly off may work on a fresh lock and then start to bind, stick, or wear the pins within a few months.

In Whittier, people usually call us for one of a few reasons. A family wants a spare house key for a teenager or a dog walker. A tenant needs an extra apartment key for a partner. A shop owner needs several office keys for new staff. Or someone just found out the only key to the mailbox is the one already in the box. Each of those is a different key, and each deserves a slightly different approach.

Our job is to look at the key you hold, tell you plainly whether it can be copied, and cut it accurately. If it cannot be copied the easy way, we tell you why and what the options are, rather than cutting something that might fail in your lock.

How do we duplicate a key, step by step?

Whether you come to our Westwood storefront or one of our mobile vans comes to you, the process is the same. Here is what happens.

1. We look at the original key first. We check the brand stamp, the keyway shape, and the condition of the cuts. A key worn smooth by years in a pocket is a poor starting point, and we say so.
2. We identify the right blank. The blank has to match the keyway of your lock, not just look similar. Many keys share a general shape but differ in the grooves along the blade, and a wrong blank can jam in the cylinder.
3. We check whether the key is restricted or high-security. If it carries a restricted stamp or a patented profile, we explain the authorization it needs before we cut anything.
4. We cut the copy on a calibrated machine, matching each depth and spacing to the original. Where the original is badly worn, we may suggest cutting from the lock's code or rekeying instead, since a copy of a worn key inherits its worn cuts.
5. We deburr the new key, removing the fine metal burrs left by cutting. Burrs are a common reason a fresh copy feels rough and wears the lock.
6. We test the copy in the lock whenever the lock is available to us, including turning the bolt or latch fully. If you are at the storefront and the lock is at home, we recommend you try it right away and bring it back if it does not run smoothly.

Which keys can we copy?

Most of what people bring us falls into a few groups. Here is how each one works in practice.

• House key copy and spare house key: standard residential keys for entry knobs, levers, and deadbolts. These are the most common requests and usually the quickest.
• Duplicate deadbolt key: deadbolt keys are often a different keyway from the knob on the same door, so we copy each one by its own blank rather than assuming they match. Some homes have the knob and deadbolt keyed alike, and some do not.
• Apartment key copy: building entry, unit door, and sometimes a mail or storage key. Some property managers restrict copies, so we may ask for permission from the property manager or landlord where a key is stamped or marked.
• Office key duplication and commercial key duplication: suite doors, file cabinets, desk locks, and back-of-house keys. If the keys belong to a master-key system, copying them is a different matter, covered below.
• Mailbox key duplication: small, flat keys for cluster boxes and individual mailboxes. If you have lost every key, copying is not possible and the lock itself usually needs work. See our page on mailbox lock replacement for that situation.
• High security key duplication and restricted key duplication: patented or controlled profiles that are deliberately hard to copy. These generally need proof of authorization, a key card, or factory involvement. We explain which route your key requires. For a wider look at these locks, see our guide to high-security locks.

What about master-key and car keys?

A key that is part of a master-key system should not be copied casually. A copy of a master or sub-master opens more doors than the person holding it may be meant to reach, which is a security question for whoever manages the system. If you run a building or office with a system in place, talk to us about master key systems so that new keys are issued under a clear record rather than cut ad hoc.

Vehicle keys are a separate subject. Many modern car keys contain electronics that must be programmed, and the details depend on the make, model, and year. We do not guess on those. We confirm by VIN and in person, and we tell you plainly if a particular vehicle is dealer-only. Start with our page on car key replacement instead of expecting a simple cut at the machine.

What affects the cost of key duplication?

We do not quote numbers on a web page because the honest answer depends on the key in your hand. These are the things that move the cost, roughly in order of how much they matter.

The type of key is the biggest factor. A standard brass house key is the lighter-cost end of the work. A high-security or restricted key uses a more expensive blank, more machine setup, and sometimes an authorization step, so it costs more. Keys with unusual shapes, such as old mortise keys or some antique skeleton keys, may need a blank to be filed or fabricated by hand.

Quantity also matters. Several copies of the same key are usually more economical per key than a single one, because the setup is done once.

Condition of the original comes next. A clean, crisp original makes a clean copy. A worn or bent original may take extra time to read accurately, and in some cases we recommend a different approach.

Finally, location and timing play a part. Coming to our storefront is usually the more economical route. A mobile visit adds travel, and after-hours service adds to that, since we are pulling a technician and a van out at a time that is not ordinary working hours. We tell you what applies before we start, so there are no surprises after the work.

Should we come to you, or should you come to us?

Our storefront is at 10740 Wilshire Blvd in Westwood, about 24 miles from Whittier, so many Whittier customers prefer a mobile visit to a drive. If you need a couple of copies of a common key and you are already going to be on the west side, the storefront is the more economical choice.

Mobile key duplication makes more sense in several situations: you have a number of keys to cut, you are not able to leave your home or business, the lock itself needs to be checked while we copy the key, or you want a new key tested in the actual door. Our vans carry key machines and a wide range of blanks, so a visit can often cover cutting, testing, and a quick adjustment on site. Details on how that works are on our mobile locksmith page.

The phone line is answered 24 hours a day, every day of the year, at (213) 577-1366. Most duplication is planned work, but if you are locked out or have lost your only key, call at any hour and we will tell you what makes sense.

What does key duplication look like around Whittier?

Whittier is an older city with an unusual mix of housing, and that shapes the key work we see here. The city's 1887 Quaker-founding period left Victorian-era and Craftsman homes around Uptown Whittier and Whittier College, many still with original mortise locksets and vintage hardware. Those old keys are not like modern ones. They can be long, with unusual bits, and blanks for them are not always on a shelf. If you have an old mortise key in College Hills or near Uptown, bring it by or call, and we will see whether it can be matched, filed from a similar blank, or whether the lock needs attention. If an old lock is sticking or failing, our lock repair service is the next step.

Climate comes into it too. Whittier sits against the Puente Hills and runs warmer than the coastal plain, and the wet-winter, dry-summer cycle swells and shrinks the old wood doors common in the historic districts. A new copy that seems to stick in winter may not be the key at all; the door may have swollen against its strike. We test a copy and look at how the door is behaving before anyone decides the key is at fault.

East Whittier is mostly mid-century ranch tracts, where the typical request is simple: a few spare house keys and a duplicate deadbolt key for a family that has grown. Friendly Hills and Rideout Heights have larger custom hillside homes, often with several exterior doors, side gates, and garages, each on its own key. When a household in those neighborhoods ends up with a pile of mismatched keys, we sometimes suggest rekeying the locks so one key runs everything, rather than cutting yet another copy.

Apartments concentrate near Uptown and along Whittier Boulevard, and student rentals cluster near Whittier College. In shared housing, spare keys disappear quickly. Roommates move out with a key, and nobody knows how many copies exist. Landlords and property managers can make this simpler through a planned approach with us; see our page on locksmith services for landlords. On the commercial side, shops along the Greenleaf Avenue district in Uptown often need office and back-door keys cut, and Whittwood Town Center businesses may involve master-key arrangements where we want to confirm authorization first.

We serve all six Whittier ZIP codes, 90601 through 90606, along with the surrounding areas.

Why call Wilshire Lock & Key for duplicate keys?

We have been in business since 1987, and key cutting is one of the oldest things we do. That experience shows up in small ways: knowing a key is worn before it goes on the machine, recognizing a blank by feel, and telling you when a copy is a bad idea.

We are one company with a storefront and our own mobile vans. There is no dispatch middleman who takes your call and sends someone you have never heard of. The person who tells you what to expect is part of the same operation that does the work. David, our owner and lead technician, oversees how we do the job, from how we handle restricted keys to when we say no.

We also tell you when a copy is not the right answer. Sometimes the honest recommendation is a rekey, a repair, or a new lock, and sometimes it is that the key you have is fine and the problem is somewhere else.

What should you check before giving a key to any locksmith?

Keys are access to your home or business, so it is reasonable to ask questions first. California requires locksmith companies to hold a license from the Bureau of Security and Investigative Services, known as a BSIS LCO license. Ask any locksmith you are thinking of using for that license number and check it with the state. It is a fair question and a good company will not mind answering it.

Also ask who is cutting the key, where, and whether they will keep any record or code of it. For restricted or high-security keys, be wary of anyone who offers to copy a controlled key with no authorization at all. That is a sign something is off, either with the key or with the shop.

If a key broke inside the lock rather than needing a copy, that is a different job. See our page on broken key extraction rather than trying to force it.
