San Bernardino Key Duplication for Worn, Restricted and Everyday Keys
Short answer: You don't need to drive to a key counter. Julian's Locksmith brings blanks, a code cutter and a duplicator to homes and businesses in San Bernardino seven days a week, from 6:30 a.m. to 11:30 p.m. Gather every key you want copied before we arrive, and have photo ID ready if we're cutting from a code instead of an existing key.

Some keys can be copied on the spot, some need paperwork and a few shouldn't be copied at all. Julian's Locksmith tells you which is which before any metal gets cut. Standard house, apartment, padlock and cabinet keys we cut and test at your San Bernardino address. Restricted and high-security keys go through the person and channel registered with the system. A car key with a transponder chip needs that chip cloned or programmed, not just a blade cut, and the carrier's arrow key on a postal cluster box belongs to the Postal Service, period. Call (951) 903-3193, describe the key and any stamps on its head, and we'll give you a straight answer and a quote.
A key copied from a copy of a copy drifts away from the original cuts, which is the most common reason a duplicate in San Bernardino sticks, wobbles or refuses to turn. Landlords near Cal State and on the Westside see it constantly: a unit key passes through tenants, roommates and contractors, and every generation adds a little error. We copy two ways. Tracing is quick and fine for a clean key. When the original is worn, we cut by code or decode the lock itself, which gives you factory depths rather than a copy of the wear. Mobile duplication means the key machine comes to your driveway or office, so you can test the new key in the actual lock before we leave. Some keys are different. Restricted keyways such as Medeco, Mul-T-Lock and Schlage Primus are cut only for the authorized holder, and we ask for your authorization card or proof that you are the account holder. A stamp like Do Not Duplicate is a request we honor by asking for authorization first. Mailbox, padlock, car and smart-key blanks each have their own rules.
Key Duplication in San Bernardino: what to expect
The first decision in any key duplication job is the blank, and getting it wrong is the most common reason a copy won't even slide into the lock. Residential keyways come in families. Kwikset's KW1 and Schlage's SC1 are five-pin profiles; their six-pin cousins, KW10 and SC4, are longer. A five-pin blank cut to perfection will never run a six-pin cylinder. Beyond the big two, older homes across San Bernardino County still carry Weiser, Weslock, Yale, Arrow and Sargent keyways, each with its own groove pattern. Material matters too. Nickel-silver blanks resist bending and wear better than plain brass, which is worth it for a key that turns a stiff deadbolt several times a day. Thin decorative blanks are fine for a seldom-used spare but can twist in a tight lock. Specialty keys need their own tooling: dimple keys have cuts drilled into the flat face, tubular keys have cuts arranged in a ring, and many cabinet and mailbox keys use small wafer-lock profiles. We identify the blank before cutting, and if it isn't on the van, we tell you how long it takes to get.
How we can help in San Bernardino
- House and apartment key copies. Need four keys for the household and one for a neighbor? We cut the whole batch from a single decoded bitting, so every copy is identical instead of each one drifting slightly from the last. Colored heads or rubber key caps help family members tell the front-door key from the side-door key at a glance.
- Code cutting and worn-key restoration. If the original packaging, a code tag or a number stamped on the key head survived, dig it out. A key code lets us cut a factory-spec key without relying on any physical copy. We still check the result against your lock, since a previous owner may have rekeyed without updating the paperwork.
- Restricted and high-security keys. Copies of a restricted key come from the company that registered the system, released once the authorized person on the account approves them. If that company isn't us, we can't bypass that arrangement, and you wouldn't want a locksmith who would. That registration is exactly what you paid for when you chose restricted keys.
- Padlock and gate keys. Gate keys spend their lives outdoors. Sun, dust and sprinkler overspray wear keyways and keys faster than an indoor lock would. When we copy a gate key in San Bernardino, we also check whether the cylinder needs cleaning and lubrication so the new key doesn't grind against grit on day one.
- RV, trailer, toolbox and older vehicle keys. Older cars and trucks built before transponder chips became standard, plus many motorcycles, boats and ATVs, use plain mechanical keys. We cut those by code or from your key. For a chipped key, cutting the blade is only half the job; the chip has to be cloned or programmed through our car key service.
How San Bernardino shapes the job
Inland heat around San Bernardino doesn't hurt brass keys much, but it bakes lubricant out of cylinders and dries out the plastic heads on vehicle and remote keys. Summer dust in the keyway can make an accurate copy feel stiff. If a new key drags, have the lock cleaned and dry-lubricated before blaming the copy. Keep spares indoors rather than in a glove box that cooks all afternoon.
Commuters leaving San Bernardino before sunrise need keys that work on the first try in the dark. A worn key that needs jiggling costs time you don't have, and a fresh code-cut key tested with the door closed fixes that. Keep a spare house key somewhere other than your car, since a key ring lost at a park-and-ride often takes the house key and the car key together.
Warehouses and distribution sites around San Bernardino cycle through staff and contractors quickly, and dock doors, offices, cages and yard gates all need keys. Duplicating more copies of an uncontrolled key only spreads it further. We cut authorized copies, stamp numbers, and help managers move high-turnover areas onto a restricted keyway where only named signers can order keys. Yard and trailer padlocks can be keyed alike.
Example situations
A Westside property manager hands over a tenant key that has been copied so many times the newest copy has to be jiggled to turn. Instead of tracing it again, we would read the lock with a decoder, cut a key to factory specs and test it in the unit's deadbolt. While we are at the curb, the manager asks for six more of the same key for a maintenance crew, so we cut and label them on the van and note the count for the next turnover.
- For example, a contractor's office runs Medeco cylinders and needs a key for a new project manager. The owner has the key card, but it lists only a former partner as an authorized signer. We explain that the registration must be updated with the dealer or manufacturer that holds it before a copy can be ordered, and help the owner work out where the system is registered.
- For example, a family in the 92404 ZIP code wants a house key for a teenager who just started driving to school. We copy it on a nickel-silver blank, sturdier for a ring that will be dropped and stuffed into backpacks. We don't copy the car key that day: its thick plastic head holds a transponder, so a metal copy wouldn't start the engine, and that becomes a separate programming appointment.
- For example, a medical office near National Orange Show Events Center needs extra keys for medication cabinets fitted with small cam locks. The office manager signs off, and we notice the cabinets all use a common factory key code. We copy the keys requested, then recommend moving the controlled-substance cabinet to a cam lock with a less common key, so a generic key from the same series won't open it.
How the visit works
- Tell us about the keys. When you call, describe each key: the brand stamped on the bow, any numbers, and what it opens. A clear photo of both sides helps us bring the right blanks. Mention stamps like Do Not Duplicate or a key number, since those change what we'll need from you.
- Confirm authorization where it applies. Tenants copying a key to their own unit on a standard blank are usually fine. Leasing office keys stamped Do Not Duplicate, pool and gate keys, and keys to common areas belong to the property, so we ask for a note or a call from management before cutting any of them.
- Identify the blank and read the wear. Matching the blank means more than finding one that slides in. Look-alike profiles can enter a cylinder and still drag against the wards or sit a hair low. We compare against reference blanks, confirm five-pin or six-pin length, and choose brass or nickel silver based on how hard the key works.
- Cut by duplication or by code. Clean originals go into the duplicator, clamped square at the shoulder so the spacing lines up. Worn originals are cut on a code machine to the decoded bitting. Either way, we compare the copy against the original side by side and measure any cut that looks even slightly off.
- Deburr, finish and mark. Finishing also covers marking. If your keys differ by door, we can add colored caps or tags so each one is easy to find. For business keys, we stamp control numbers on request and list them for your records before we hand anything over.
- Test in the lock and hand over. We try each copy in the lock it belongs to, locking and unlocking, with the door open and then closed. A key that turns freely with the door open can bind once the bolt presses on a misaligned strike. If something's off, we fix the key or point out the door problem.
How we quote the job
- Tracing versus decoding. A key that's bent, cracked or missing part of a cut takes more interpretation, sometimes including a test cut and an adjustment at the lock. The more guesswork the original forces, the longer the job runs. Bringing out the least-used key in the house can shorten it.
- Quantity and number of key patterns. Ordering copies for a whole household or staff at once usually costs less per key than adding one at a time over several visits. Think through who needs access: spouse, kids, a neighbor, a caregiver, the cleaner. Then order the set in one trip and keep track of who holds which.
- Lock condition and keys made from scratch. Originating a key means picking or decoding the lock, sometimes removing the cylinder, and confirming ownership first. It's more involved than duplication but often cheaper than new hardware. For high-security cylinders, origination may not be possible, and replacement becomes the realistic path.

What not to do
- Copying a transponder car key on a plain metal blank. The copy slides into the ignition and may even turn, but the immobilizer won't recognize it, so the engine won't run. Check whether the key head holds a chip before paying for a metal-only copy.
- Using a key that's cracked near the bow. A crack at the shoulder usually means the key is one hard turn away from breaking inside the lock. Get it decoded and replaced while it's still in one piece; a broken-off blade means an extraction before any copy can be made.
- Copying the copy. Each traced generation adds a little error, and after a few rounds the newest key barely works. Go back to the original, or have the key decoded and cut to code, so the next spare is made from the correct numbers instead of the latest approximation.
Advice before you book
- Label spares without naming the address. Use colored caps or a code only your household understands instead of writing your street on a tag. If a labeled ring goes missing in San Bernardino, it shouldn't lead anyone straight to the door it opens.
- Skip novelty printed keys for important locks. Colorful patterned keys are fun, but many are softer than plain brass and more likely to bend or snap in a stiff deadbolt. A key broken off in your front door costs more to fix than the plain spare would have.
- Copy from your best key, not your daily one. The key on your keychain has been pushed into the lock thousands of times and carries the most wear. The spare in the kitchen drawer, or the one that came in the box with the lock, makes a far better source for new copies.
- Don't post photos of your keys online. A sharp picture of a key's cuts is enough for someone with the right knowledge to work out the bitting. Crop keys out of new-homeowner celebration photos, and keep them off the desk during video calls.

Frequently asked questions
Will you copy a key to a school or government building?
Only with written authorization from the person in charge of that building or their designated representative. California law makes it a misdemeanor to knowingly copy a key to a building controlled by the state, a county, a city or a public school or community college district without that authorization. Staff members should request additional keys through their facilities office.
Can you copy my car key?
Plain metal keys for older cars, trailers, RVs, boats and motorcycles, yes. Most cars from the late 1990s onward use transponder keys, and a metal-only copy won't start the engine. For those, we cut and program a new key through our car key service. If you're not sure which kind you have, give us the year, make and model and we'll tell you.
Why doesn't my new copy work when the old key does?
There are a few possibilities. The copy might be on a look-alike blank, cut slightly off at the shoulder, or carrying a burr. Or the original may be so worn that the lock has adapted to it, so a correct key feels wrong. We test both keys in the lock to find out which is true, then fix the key or service the cylinder.
Why do some copied keys snap?
Thin novelty blanks, cuts made too deep, and keys forced into stiff locks are the usual causes. A very deep cut next to a shallow one leaves a narrow neck that can crack over time. We cut within each manufacturer's limits on neighboring cuts, use brass or nickel silver for daily keys, and flag any lock that needs servicing before it breaks a key.
What are dimple and tubular keys, and can you copy them?
Dimple keys have shallow drilled cuts on the flat faces instead of notches along the edge, and they turn up on some higher-security locks. Tubular keys have cuts arranged around a round shaft and appear on bike locks, vending machines and certain cabinets. Both need dedicated machines and blanks. We copy common versions and tell you when a particular profile has to be ordered.
How many spare keys should a household keep?
Enough to cover every regular user plus one or two true backups, and no more. A typical household might want one per adult, one for a trusted neighbor, and one stored safely indoors. Every extra copy is a key you need to account for, so hand them out deliberately and keep a simple list of who has which.
How quickly can you get to an address in San Bernardino?
We're based in San Bernardino, so most addresses in town are a short drive. Arrival time still depends on traffic and on the job the technician is finishing, so we give you an estimate on the phone before you commit.
