What key duplication really involves

Most people think of key copying as a thirty-second job at a hardware store counter. Sometimes it is. But a copy that looks right and a copy that works smoothly in your lock are two different things, and the gap between them is where most frustration comes from. A key is a set of cuts measured in thousandths of an inch. If the cutting machine is slightly out of calibration, or if the blank is the wrong profile, or if the original is worn and the copy inherits that wear, you get a key that goes in but fights you at the turn.

At Wilshire Lock & Key we have been cutting keys since 1987, and the single most useful habit we have learned is to check the copy in a lock before it leaves our hands. A duplicate that only works if you jiggle it is not a finished job. If you are in Compton and need a spare house key, an apartment key copy, an office key, or a mailbox key, this page explains how we handle each, what changes the cost, and when copying is the wrong move.

We take calls any hour of the day or night, every day of the year, at (213) 577-1366. Key duplication is usually a planned errand rather than an emergency, but the people who call us late at night are often the ones who just realized they have only one key left, and we would rather you make the copy before that key goes missing.

Which keys can we copy for homes, offices, and mailboxes?

Most keys in everyday use are straightforward to duplicate. The list below covers what Compton customers bring us most often, along with the honest caveats for each.

Where a key falls outside this list, tell us what it opens and we will say plainly whether we can copy it, whether it needs authorization, or whether a different solution makes more sense.

  • House keys and spare house keys for standard pin-tumbler locks, including the front door, back door, and side gates.
  • Duplicate deadbolt keys. Deadbolts often use a different keyway than the knob lock on the same door, so we match each key to its own lock rather than assuming they are the same.
  • Apartment key copies, as long as the key is not stamped or registered as restricted by the property or lock manufacturer.
  • Office key duplication and commercial key duplication for suites, storerooms, and back-of-house doors, including doors that share one keyway under a master key system.
  • Mailbox key duplication for private and commercial mailboxes. Postal-owned boxes are controlled by the Postal Service, so those keys come from them, not from us.
  • Security screen door keys and window-bar lock keys, which are common on Compton houses and use their own small keyways.
  • Padlock, shed, and outbuilding keys, including the keys for gates and barns.
  • High-security and restricted keys, with the limits described in a separate section below.

How do we duplicate a key, step by step?

The process is simple, but the order matters. Skipping the inspection or the test is how bad copies get made.

  1. Look at the original. We check for wear, bends, and cracks. A badly worn key makes a badly worn copy, and a bent key can cut off-angle.
  2. Identify the keyway and find the matching blank. The wrong blank can fit just well enough to cut and then fail in the lock. The brand and keyway stamped on the key help, and we confirm it by eye and by test fit.
  3. Check for restrictions. If the key is stamped or part of a restricted system, we stop and explain the options before cutting anything.
  4. Cut the copy on a calibrated machine, following the original's depths and spacing.
  5. Deburr the new key. Fresh cuts leave tiny metal burrs that rough up a lock and make the key feel gritty.
  6. Test the copy. Whenever the lock is available, such as a mobile visit, we try the new key in the actual lock. In the shop, we compare it against the original and test it in a matching cylinder.
  7. Hand it back with a plain note about anything we noticed, such as a worn original, a sticking lock, or a key that is overdue for replacement.

Restricted and high-security keys: what we can and cannot copy

Some keys are deliberately hard to copy. Restricted keyways and high security key duplication exist so that a stranger cannot walk into a shop and have a copy of your key made in a few minutes. If your key is marked with a do-not-duplicate stamp, know that the stamp alone is often a request rather than a legal barrier. What actually protects you is the lock system behind it: a restricted blank that is only sold to authorized dealers, and a registration process that identifies who may order copies.

In practice that means three possible outcomes. Some high security keys we can copy in person, with proof that you are the owner or authorized user. Some need a factory authorization card or an order through the lock manufacturer's system, which takes longer than a standard cut. And some are dealer-only, meaning that we cannot cut them at all without the manufacturer's involvement. We will tell you which category your key falls in, and we will not cut a key we should not cut just to close a job.

If your restricted key system is old or you cannot find the paperwork, the better path may be upgrading to high-security locks with a documented key control process. That is a different project from duplication, but it is worth knowing about if you keep losing track of who holds a copy.

What affects the cost of duplicate keys in Compton?

We do not quote numbers on a web page, because the real figure depends on the key in your hand. What we can do is explain what moves the cost up or down, so that when you call you understand the quote.

A plain, common house key is the lighter-cost end of the range, because blanks are easy to source and cutting is quick. Costs rise with each of these factors:

  • Key type. Standard brass keys are the most economical route. Dimple keys, paracentric keyways, and high-security profiles use costlier blanks and more precise cutting.
  • Restricted status. Keys that need authorization or a factory order add time and handling.
  • Quantity. Several copies cut in one visit are more efficient than separate trips.
  • Location. Cutting at our storefront is usually the more economical route. A mobile visit adds travel, which matters because Compton is about 20 miles from our Westwood base.
  • Condition of the original. A worn key may need to be cut by code or by decoding the lock rather than by tracing, which takes longer.
  • Time of day. Calls outside normal business hours may be priced differently, since someone is staffing the phones and van overnight.
  • Whether the lock itself needs attention. If the copy will not work because the lock is worn, that is a repair question, separate from the key.

Key duplication around Compton: homes, Richland Farms, and commercial corridors

Compton's housing and layout shape what people ask us to copy. Across ZIP codes 90220, 90221, and 90222, most homes are single-family. Near downtown there are 1920s bungalows, and across much of the city the houses are late-1940s and 1950s tract homes. Locks in houses that age have often been through several owners, and the keys in circulation are often third or fourth generation copies. Copies of copies drift. If your spare house key sticks, the cause is often that it was cut from a copy that was itself cut from a copy. Cutting a fresh key from the best available original, or by decoding the lock, usually cures it. If you are not sure how many people still have keys to your house, a rekey is the better step than another duplicate.

Security screen doors and window bars are common on Compton homes, and each one adds a key. A household can end up with a front door key, a deadbolt key, a screen door key, a back gate key, and a window-bar key, all on one ring. When you ask for a spare, we suggest copying the whole set at once and labeling each, so that nobody is guessing at the next lockout. Older wood doors in this area can also swell in damp winter mornings, when the marine layer rolls in, which makes a lock bind. A tight lock is not a bad key, and cutting another copy will not fix it. We would rather check the door than sell you a key that does not help.

In Richland Farms, the large agricultural-zoned lots with barns, corrals, and horse-keeping bring a different kind of key work. A single property may have a house lock, a pasture gate padlock, a barn lock, and one or more outbuilding locks, often on different brands bought over many years. Duplicating these is mostly about matching old padlocks and weathered keys, and about keeping a clearly labeled set so that a ranch hand or a family member can get to the barn without borrowing the main house key. If a gate latch or chain lock is failing, that is a gate lock repair job rather than a key job.

Along Compton Boulevard and Long Beach Boulevard, where storefronts and roll-up gates are part of daily life, the questions are about commercial key duplication: how many employees need a key, whether the gate lock and the front door share a keyway, and how to avoid handing out the only key to a part-time worker. In Downtown Compton, Sunny Cove, Leland, the Compton College area, and along the Rosecrans Avenue corridor, we also get requests for apartment and office copies. For anyone managing many doors, a master key system can reduce a heavy ring to one key per person, though it is a bigger project than simple copying.

Mobile key duplication and shop visits

You can bring your keys to our storefront at 10740 Wilshire Blvd in Westwood, or we can come to you. A mobile locksmith visit makes the most sense when the keys cannot leave the property, when the lock itself needs to be tested with the new key, when you manage several doors, or when the original key is in a lock that needs decoding on site.

For a single common house key, coming to the shop is usually the more economical route. For a business owner who cannot close the register, a property with many locks, or a rancher who does not want to leave animals unattended, a van visit saves a trip. Tell us the situation on the phone and we will say which approach fits.

We are one company with our own storefront and our own vans, so the person who answers the phone is not a dispatcher passing your request to an unknown contractor.

Mailbox keys and small locks

Mailbox key duplication is a small job that often turns out to be more complicated than expected. If the box belongs to a private building, a business, or a standalone residential mailbox, we can usually cut a copy or replace the lock. If the box is a Postal Service cluster unit or a postal-owned lock, the Postal Service controls the keys, and we are not the right place to get one.

If the key is lost and you do not have an original to copy, duplication is not possible. In that case a lock replacement is the way forward, and our page on mailbox lock replacement covers it. The same applies to filing cabinets, desk drawers, and cash drawers in a small office: if you have a key we can copy it, and if you do not, we can discuss opening or replacing the lock.

Why call Wilshire Lock & Key for key copying?

We have been in business since 1987, and David, who owns the company and leads the technical work, oversees how we operate. We serve 140 cities across Los Angeles and Ventura counties, Compton included, from a real storefront with real vans.

California requires locksmith companies to hold a Bureau of Security and Investigative Services locksmith company license, known as a BSIS LCO license. You should ask any locksmith, including us, for that license number before work begins. A key shop that cannot name its license is a warning sign, especially for restricted keys.

Our approach to key duplication comes down to a few habits: we match the blank rather than eyeball it, we deburr and test every key, we tell you when an original is too worn to trust, and we do not cut restricted keys without proper authorization. We would rather lose a small job than hand you a key that does not work or one that should not exist.

When duplicating a key is not the right answer

Copying is not always the fix. If you have lost a key and do not know where it went, a duplicate of your remaining key leaves the lost one active. Having the lock rekeyed means the old key stops working while new keys are cut to fit. If a key broke in the lock, the first step is broken key extraction, not another copy. And if you need a spare for a vehicle, that involves programming and sometimes chips, which is its own category; see our page on car key replacement. We confirm vehicle key details by VIN or in person rather than guessing over the phone.

For a house key, the simple rule is this: if you know where every key is, duplicate. If you do not, rekey.

Frequently asked questions

Can you copy a key that says Do Not Duplicate?

Sometimes. The stamp is often a request, not a legal block, but we do not treat it lightly. We look at whether the key belongs to a restricted system, ask who you are and what the key opens, and decide from there. If the key needs manufacturer authorization, we will say so rather than cut it anyway.

Do I need to bring the original key?

Yes, for duplication we need a working original, or access to the lock so we can decode it. If you have lost every key, copying is not possible and the solution is usually rekeying or replacing the lock.

Will the copy work as smoothly as my original?

It should work as well as the original, and often better if your original is worn. We deburr and test each copy. If your original is badly worn, we will tell you, because a copy cut from a worn key may still stick.

Can you come to my Compton home or business to copy keys?

Yes. We run mobile service vans and serve Compton from our Westwood base. Call (213) 577-1366 and describe the keys and the locks, and we will tell you whether a mobile visit or a shop drop-off makes more sense.

Can you duplicate a deadbolt key?

Yes, in most cases. Deadbolts often have a different keyway than the doorknob, so we match each key separately. If you are unsure which key goes with which lock, bring all of them or tell us what each one opens.

Why does my new copy stick when the original does not?

A few causes: the blank may be the wrong profile, the burrs may not have been removed, or the machine may have been off. Bring it in and we will check the cut against the original. If the lock itself is worn or the door has swollen, a good key may still feel tight, and we can look at that too.

Can you copy apartment keys?

Often yes, as long as the key is not restricted and you are authorized to have a copy. Some buildings require you to get keys through management, and some leases forbid copies. Check your lease first, since changing or adding keys without permission can cause problems.

How much will duplicate keys cost?

It depends on key type, restricted status, quantity, location, and whether we come to you. A plain house key is the lighter-cost end. Call (213) 577-1366 with a description of the key and we will explain what applies.

Do you duplicate office and commercial keys?

Yes. We handle office key duplication and commercial key duplication, including doors on a shared keyway. If your business has grown and keys are out of control, ask us about a more organized key system.
