Why do some key copies work badly, or not at all?
A key is a small piece of metal that has to match the pin heights inside your lock within a very tight tolerance. A copy that is off by a hair can still slide in, but it will drag, stick, or need jiggling before the cylinder turns. That is the copy people end up cursing at the front door at the end of a long day.
Most bad copies come from the same few causes. The blank was the wrong profile for the keyway. The cutting machine was out of adjustment. The original being traced was itself worn, so the copy inherited the wear and added its own. Or the copy was made from another copy, and every generation drifts a little further from the original cuts. We have been cutting keys since 1987, and the single most useful habit we have is simple: test the new key in the lock, not just on the bench.
Key duplication sounds like the most basic thing a locksmith does, and in a way it is. But basic does not mean careless. A spare house key you can trust is worth a lot more than a handful of loose ones that only work if you lean on the door.
How do we duplicate a key, step by step?
The process is the same whether you walk into our Westwood storefront at 10740 Wilshire Blvd or we handle it at your door. Here is what actually happens.
- We look at the original key. We check the stamping, the shape of the head, the keyway profile, and how worn the cuts are. If the original is badly worn, we tell you before we cut anything.
- We identify the correct blank. Keys that look alike across a counter can have different grooves, shoulders, or lengths, and the wrong blank is the quiet cause of many failed copies.
- We cut the copy, then remove the burrs left by cutting. A rough edge catches inside the lock and wears the pins faster than you would expect.
- We test the new key in the lock it belongs to whenever that lock is available to us. If the lock is not with us, we test the copy against the original and tell you plainly that it has not been tried in your door yet.
- If the copy does not turn smoothly, we adjust it or re-cut it. We do not hand over a key that we would not use ourselves.
- We suggest labeling and sorting spares so you know which key belongs to which door, then hand everything back, including the original.

Call (213) 577-1366Which kinds of keys can we copy?
Our key cutting service covers the range of keys a Baldwin Park household, landlord, or small business is likely to carry. Some of these are routine and some come with caveats, so here is the honest breakdown.
- House keys and spare house keys: standard residential keys for front doors, back doors, side gates, and garage entries.
- Duplicate deadbolt keys: deadbolts often use a different keyway from the knob lock beside them, so we match each key to its own lock instead of assuming they are the same.
- Apartment key copies: keys for unit doors, building entries, and shared laundry or storage rooms, as long as the key is not restricted (more on that below).
- Office key duplication and commercial key duplication: keys for suite doors, storefronts, filing cabinets, and desks.
- Mailbox key duplication: small flat keys for cluster boxes and private mailboxes. If the key is lost entirely, copying is not an option and the lock needs service instead. See our page on mailbox lock replacement.
- High security key duplication: keys with sidebars, dimple cuts, or other advanced profiles. These take different equipment, and some can only be copied with the right authorization.
- Restricted key duplication: keys on controlled keyways, where the manufacturer limits who may order copies.
What about high security and restricted keys?
This is where being straight with you matters. Many people assume that a key stamped 'Do Not Duplicate' cannot be copied. The stamp on its own is only a request. What truly restricts a key is a controlled keyway, where the manufacturer or a key system owner decides who can order additional keys, usually through an authorization card or a registered account.
If your key is on a controlled system, we will not cut it without proper authorization. That protects you as much as anyone, because it means a stranger cannot walk in and copy the key to your property. If you hold the authorization, bring it. If you do not, the practical route is usually to contact whoever set up the system, such as a property manager, building owner, or your employer's facilities contact. In some cases the better answer is a new lock and new keys, and we can talk through options like high security locks with you.
Some high security keys can be duplicated at a storefront with the right machine, and some need to be ordered or coded by the manufacturer. We tell you which situation you are in before any work starts, so you are not left waiting on something that cannot happen.

Call (213) 577-1366What affects the cost of duplicate keys in Baldwin Park?
We do not quote numbers on a web page, because the honest answer depends on the key in your hand. Here is what moves the cost up or down.
The type of key is the biggest factor. A plain brass house key is a simple cut. A high security key or a key with a unique profile needs a specialized blank and often more time. Restricted keys can involve authorization steps that a basic copy does not.
Quantity matters in a practical way. Several keys cut in one visit are usually the more economical route compared with returning again and again for one at a time.
Where the work happens also plays a role. Coming to our storefront is the lighter-cost option for a straightforward copy. If you want us to come to you, there is a service element on top of the cutting itself, which depends on location and timing. After-hours requests are treated differently from daytime ones.
Finally, the condition of the original counts. A badly worn key may need extra attention, or the better recommendation may be to have the lock re-keyed rather than copy a key that no longer matches well. We will tell you which, and you decide. Call (213) 577-1366 and describe the key, and we can tell you what kind of job it is.
Should you copy the key or rekey the lock instead?
Copying a key and re-keying a lock solve different problems, and mixing them up is a common source of wasted money. Copying gives more people access to the lock you already have. Rekeying changes the lock so that old keys stop working.
Copy the key when you simply want more access and you know where every existing key is. That is the case when a family member needs a spare, or you want a spare to leave with a trusted neighbor.
Rekey instead when you do not know who has a key. That includes a new home, a former roommate, a tenant who moved out, an ex-employee, or a key that was lost somewhere you cannot trace. In those cases, another copy only adds to the problem. Our lock rekey service changes the pins so the old keys no longer work, and then we cut fresh keys to match.
If you are standing outside a door right now with no key at all, that is a different situation, and our house lockout help page covers it. Once you are back inside, duplication is the sensible next step so it does not happen twice.

Call (213) 577-1366Key duplication around Baldwin Park: homes, apartments, and storefronts
Baldwin Park (ZIP 91706) has a housing mix that shapes the way people use spare keys. Much of the city is made up of 1950s-era tract bungalows and ranch homes, with high owner occupancy and many multigenerational households. In a house where several adults, grandparents, and older kids come and go on different schedules, one or two keys are rarely enough. People tend to need a real set of spares, and they need them to work on the first try. In the Morgan Park area and on similar tract blocks, we regularly see the same scenario: a family with one worn key that has been copied from a copy, and a door that has to be pulled and lifted to open. A clean copy cut from a good original, tested in the lock, takes care of it.
Accessory units and garage conversions are common here too, and each of those often has its own door and its own key. That adds up to more keys per property than the original floor plan suggests. Security screen doors are also a frequent retrofit in Baldwin Park, which can mean a second lock and a second key at the same entry. When we copy keys for a house, we make a point of asking how many separate doors the keys cover, so nothing gets missed.
Apartment buildings cluster along Ramona Boulevard and near the Metrolink station district. For tenants there, apartment key copy requests usually involve unit keys, building entry keys, and sometimes a mailbox key. Check your lease before copying, because some buildings control their keys or use restricted keyways, and we will not cut those without authorization. Landlords and managers with several units can look at our locksmith services for landlords.
Downtown Baldwin Park, around Maine Avenue and Ramona Boulevard, has storefronts and small offices where office key duplication is a routine need. Owners often want extra keys for an opening manager, a bookkeeper, or a cleaning crew, and they want to know which key is which. Along the Francisquito Avenue corridor and the Arrow Highway industrial corridor in the north, businesses tend to carry larger rings for yard gates, side doors, and office suites. Commercial key duplication there is usually about keeping the ring organized and not having a single master copy in one pocket. If your business has outgrown a handful of loose keys, ask us about a master key system.
Heat is the other local factor. Baldwin Park gets hot inland summers, typically hotter than coastal Los Angeles, and door and frame expansion during heat waves is the most common climate-related lock complaint we hear about. A door that binds in August can make a perfectly good key feel like it is failing. Before blaming the copy, we check whether the door is the real problem. Sometimes a key that seems stiff is just a swollen door pressing the bolt against the strike.

Call (213) 577-1366When does mobile key duplication make sense?
Most people think of key cutting as something you do at a counter. That is still the lighter-cost route for a simple copy, and Baldwin Park customers are welcome to bring keys to our Westwood storefront, though we are about 29 miles from the city, so it is not a quick errand for everyone.
Mobile key duplication exists for the cases where leaving is not practical. Think of a shop owner who cannot close up to run across town, a household where the only car is in use, or a landlord turning over several units who wants every key tested on site. Depending on the key, we may be able to cut at your door from the van, or we may take the key back to the storefront and return it. We tell you which applies once we see the key.
One practical benefit of coming to you is that the copy can be tested in the actual lock right away. That removes the guesswork about whether the new key works on your specific door. For more on how our vans work, see our mobile locksmith page.
A note about car keys, since people ask. Many modern vehicle keys contain a transponder chip and cannot be duplicated by simply cutting metal. Whether a chip is involved depends on the vehicle, so we confirm by VIN or in person instead of guessing. Some vehicles may be dealer-only for certain key types, and if yours is one of them, we say so honestly. If you need programming, our transponder key programming page explains how that works. This page stays focused on the house, office, and mailbox keys that are cut mechanically.
Why call Wilshire Lock & Key for spare keys?
We have been in business since 1987, and David, the owner and lead technician, oversees the work. That matters for something as small as a copied key, because the difference between a good copy and a frustrating one is attention, not complexity.
We are one company, not a dispatch service passing your request to whoever is nearest. The person who answers the phone works for the same business that cuts your key. We have a storefront at 10740 Wilshire Blvd in Westwood and mobile service vans, and we serve 140 cities across Los Angeles and Ventura counties, Baldwin Park included. Our phone line at (213) 577-1366 is answered 24 hours a day, 7 days a week, year-round.
One more thing worth knowing: California requires locksmith companies to hold a BSIS LCO license. Ask any locksmith you call, us included, for that license number before they work on your property. It is a fair question, and a reputable company will not mind answering it.
If you are unsure what kind of key you have, or whether you should copy it or rekey the lock, call and describe the situation. We would rather tell you the simple answer over the phone than sell you the wrong job.

Call (213) 577-1366How to get more from your spare keys
A few habits keep duplicate keys useful instead of becoming a liability.
- Copy from the original, not from a copy. If your only key is already a copy, have us cut from it and check the result, or consider whether a fresh set is the better path.
- Label by door, not by address. A tag with an address on a lost key is an invitation. Use a code or a color you will remember.
- Keep one spare off the property, with someone you trust completely, rather than under a mat or in a planter.
- Replace worn keys before they fail. If a key is bending, losing its edges, or sticking, a fresh copy now is easier than a broken key in the lock later.
- Rekey when the people with access change. Moving in, a roommate leaving, or a staff change are all good moments.
Frequently asked questions
Can you copy a key marked 'Do Not Duplicate' in Baldwin Park?
Sometimes. The stamp on its own is not a legal barrier, but a truly restricted keyway is controlled by the manufacturer and needs authorization. We will check which type you have before cutting anything, and we do not cut keys on controlled systems without proper authorization.
Can I get a copy of my apartment key?
Often yes, if it is a standard key. Some apartment buildings use restricted keys or require manager approval, so check your lease or ask your property manager first. If the key is restricted, we will explain what authorization is needed.
Do you make mailbox key copies?
Yes, when you have a working mailbox key to copy from. If the key is lost entirely, copying is not possible and the lock usually needs to be replaced or rekeyed. We can help with either path.
Can you duplicate a deadbolt key?
Yes. A deadbolt often has a different keyway from the knob lock on the same door, so we match each key to its own lock. We test the copy in the deadbolt when we can.
Do you come to me for key duplication, or do I have to visit the shop?
Both options exist. You can bring keys to our Westwood storefront at 10740 Wilshire Blvd, or we can come to you with a mobile van. Depending on the key, we may cut at your location or bring it back to the shop. Call (213) 577-1366 to talk it through.
Can you copy high security keys?
Some, yes. High security keys use different blanks and equipment, and some require authorization or ordering through the manufacturer. We tell you which situation you are in before any work starts.
My key works but sticks. Is the copy bad, or is it the door?
It could be either. In Baldwin Park, heat can cause doors and frames to expand and bind a bolt, which feels like a bad key. We check the key, the lock, and the door to see which is the real cause.
Should I copy my key or rekey the lock?
Copy when you know where all the existing keys are and just want more access. Rekey when you are not sure who has a key, such as after moving in or after a tenant or employee leaves.
Can you copy a car key too?
Mechanical car keys can sometimes be cut, but many modern keys include a transponder chip that needs programming. Because it varies by vehicle, we confirm by VIN or in person, and we are upfront when a vehicle is dealer-only for a particular key.
