Key Duplication in Sierra Madre, CA

What does key duplication really involve?

Copying a key sounds like the simplest job in the trade, and the machine part of it is. The skill is in everything around the machine: reading which blank the lock actually wants, checking that your original is still true, and testing the finished copy in the lock it is meant for. A copy that looks right on the counter but drags in the cylinder is a copy that will wear out your lock and eventually snap in it.

At Wilshire Lock & Key we cut duplicate keys for houses, apartments, offices, and mailboxes, and we handle the less common requests too: a duplicate deadbolt key, a high security key, a restricted key that needs authorization. This page explains how we do it, what changes the cost, and what is specific to Sierra Madre, where a lot of the doors are older than the locks on them and older than most of the keys in people's drawers.

Why do some copied keys fail?

Most bad copies come from the same few causes. Knowing them helps you decide which key to hand over and what to ask for.

• Copying a copy. Every generation of duplicate drifts a little from the factory cut. After two or three generations the key can be off by enough to bind or to turn only if you jiggle it.
• A worn original. A key that has opened the same front door for twenty years has rounded peaks and shallow valleys. Cutting from it simply reproduces the wear.
• The wrong blank. Many keys look alike but differ in the keyway profile, the width of the shoulder, or where the key stops in the lock. A blank that is almost right will cut almost right.
• A cutting machine that is out of adjustment or a cutter that has gone dull, leaving burrs that scratch the pins inside your cylinder.
• No test. A copy that is never tried in the actual lock is a guess.

How we duplicate a key, step by step

Our process is short, and it is the same whether you walk into the storefront on Wilshire Boulevard or meet one of our mobile vans.

1. Look at the original. We check it for wear, bends, cracks, and stamped markings, and we tell you honestly if it is too worn to copy well.
2. Identify the key. We match the keyway, the brand, and the blank. If the key carries a restricted or high security marking, we stop and explain what that means before cutting anything.
3. Choose the blank. We select a blank that fits the keyway, not just one that resembles it.
4. Cut and deburr. The copy is cut to the original's bitting, then cleaned so no rough edges are left to scratch your cylinder.
5. Test it. Whenever the lock is available to us, we try the new key in it, and we compare the feel against the original. Tell us if you can bring the lock, or we can test at your door on a mobile visit.
6. Hand it back with advice. If your original is badly worn, we may suggest cutting the new key from the code or a fresh blank pattern, or replacing the cylinder, rather than letting you carry on with a tired key.

Which keys can we copy?

Most everyday keys can be copied without any fuss. A few categories need more care or paperwork, and we would rather say so up front than surprise you at the counter.

• House key copy and spare house key: standard residential keys for front doors, back doors, and side gates.
• Duplicate deadbolt key: deadbolts often use a different keyway from the knob lock beside them, so we check each one rather than assume.
• Apartment key copy: building owners and managers sometimes restrict copies. If the lease or the building requires management permission, we may ask for it.
• Office key duplication and commercial key duplication: single keys, sets for staff, and keys that belong to a larger master key system, where authorization matters.
• Mailbox key duplication: mailbox keys are small and easy to lose. If yours is gone altogether, copying is not an option, and a lock change through mailbox lock replacement is usually the route.
• High security key duplication and restricted key duplication: these keys are protected by patents or by the maker's control system. We can only cut them with the proper authorization, and sometimes only through the manufacturer. Our page on high security locks explains how those systems work.
• Keys that say 'Do Not Duplicate': that stamp is not a legal lock on the key. It is a request. On a plain key, it does not stop a machine. We will still ask whether you are the person entitled to a copy, and for restricted systems we follow the manufacturer's rules.

What about car keys with chips?

A plain metal copy of a modern car key can open the door and still fail to start the engine if the key needs a transponder chip programmed to the car. Whether a given car needs programming, and whether a dealer is the only source for a particular key, depends on the make, the model, and the year. We do not guess. We confirm by VIN and in person before telling you what is possible, and we say so plainly if a particular key turns out to be dealer-only. For anything with a chip, see our page on transponder key programming.

What affects the cost of key duplication?

We do not quote numbers on a web page, because the same request can mean different work. What moves the cost is mostly predictable:

• The type of key. A plain brass house key is the simple end of the range. Restricted, high security, and chip-equipped keys involve special blanks, controlled blank supply, or authorization steps.
• How many copies you need. A single spare and a set for a whole household or staff are priced differently, and the setup effort is shared across a bigger batch.
• The condition of the original. A clean original copies easily. A worn one may need extra care, or a different approach altogether.
• Where the work happens. Coming to the storefront is usually the more economical route. A mobile visit adds travel and the time of a technician, which makes sense when you cannot leave a property or need testing in the lock itself.
• Authorization. Keys on controlled systems require proof you are allowed to have them, and that process can add steps.
• Other work discovered on the way. If the lock itself is the real problem, we will tell you, and what you choose to do about it changes the job.

Key duplication around Sierra Madre

Sierra Madre is a small foothill town where most doors belong to older single-family homes: early-1900s cottages, Craftsman houses, and mid-century houses, with rustic cabins on narrow lanes in Sierra Madre Canyon. Multifamily housing is limited to a few small complexes near the village core. That mix shapes the kind of key work people here ask for. Older homes often carry legacy hardware, with original knob locks, mismatched deadbolts added over the decades, and keys that have been copied from copies for years. A household in the 91024 ZIP may have five different keys for a single front door and no clear idea which one is the good one.

In Sierra Madre Canyon, we often think about the cottage that has changed hands and still runs on keys nobody can account for. If you have moved in and want the old copies to stop mattering, duplicating is only half the story. The better answer is lock rekeying, after which we cut fresh copies for everyone who should have one. Narrow lanes in the canyon can complicate access, which is one reason many people there choose a mobile visit and have the cutting and testing done at the door.

Around the Kersting Court village core and along Sierra Madre Boulevard, the requests lean toward spare house keys for homes, small-office keys, and apartment key copies for the few small complexes nearby. Up on the hillside properties off the Baldwin Avenue corridor, gates and side doors matter as much as the front door, so we ask which keys you carry for the gate, the side door, and any outbuilding before we start. It is common to find the gate key is the one worn flattest.

The climate plays a part as well. Sierra Madre sits directly below the San Gabriels, with strong Santa Ana winds, hot dry summers, and heavy canyon runoff in wet winters. Sun and wind dry and crack wood doors on hillside homes, and a door that has shifted makes a lock bind. People blame the key and keep forcing it, and the key wears faster. If a new copy sticks in a lock that the original also fought, the lock or the door is the likely culprit, not the cut.

Hikers use a spare, too. The Mount Wilson Trail trailhead and Bailey Canyon Wilderness Park are close to town, and hiker car lockouts at those trailheads are a scenario we know. A spare house key kept with someone you trust, instead of hidden under a planter, is a small step that keeps a bad afternoon from getting worse.

Can you come to me for mobile key duplication?

Yes, when the job suits it. Our storefront is at 10740 Wilshire Blvd in Westwood, and Sierra Madre is about 27 miles from it, so for a single spare key many people find the trip is not worth their time and prefer that a van comes to them. Our mobile locksmith service is built for that. It is most useful when you cannot leave the property, when you need the new key tested in the actual lock, or when you need several keys cut for a household or a small office.

Some specialty blanks and restricted keys are better handled with the full shop setup or the manufacturer's process, and we will tell you if your key is one of them. We do not promise that every key can be finished on your driveway, and we do not say so just to win the call.

Why call Wilshire Lock & Key for your spare keys?

We are not complicated, and the reasons are plain.

• In business since 1987, which means we have cut keys for a very long list of older hardware, including the legacy locks common in Sierra Madre.
• A real storefront in Westwood and mobile vans, so you can bring the key to us or have us come to you.
• One company. The person who answers your call works for Wilshire Lock & Key, not for a dispatch middleman who passes your job to whoever is free.
• David, the owner and lead technician, oversees the work, so there is someone accountable for it.
• The phone at (213) 577-1366 is answered 24 hours a day, every day of the year. A lost or broken key rarely waits for business hours.
• Plain advice. If a copy will not do the job and a rekey or a new lock is the honest answer, we say that, and we have pages for each of those paths, like house lockout help for the evening when the only key is the one locked inside.

What should you ask any locksmith before handing over a key?

California requires locksmith companies to hold a license from the Bureau of Security and Investigative Services (BSIS), called a Locksmith Company (LCO) license. Ask any locksmith, including us, for that license number before work begins. A company that hesitates to give it is telling you something.

Also ask who will do the work, whether the key will be tested in the lock, and what happens if a copy fails to turn. For office or commercial keys, ask how the shop handles authorization on keys that belong to a controlled system. If your business needs more than a copy, our commercial locksmith work covers the rest. You can always reach us through the contact page or by phone.
