Key Cutting Service in Ontario
Short answer: Most keys can be cut three ways: traced from a working key, cut by code from the numbers that describe each cut, or decoded from the lock when no key exists. Tracing is fastest. Code cutting gives the cleanest result when your key is worn. Tell Julian's Locksmith at (951) 903-3193 what you have in Ontario and we'll pick the method and quote it up front.

You don't need a key in your hand to get a key cut. A working original is the easiest starting point, but a code from a lock's packaging, the numbers stamped on a worn key, or the lock itself can all supply the cuts. Julian's Locksmith provides key cutting service across Ontario from whichever starting point you have: trace a good key, cut a fresh one by code, or decode the lock when every copy is gone. Tell us what you've got when you call (951) 903-3193 and we'll quote the job. One honest limit: restricted keys need proof of authority, and some must be ordered.
How this works in Ontario
Every ordinary house key does one job: lift a row of spring-loaded pins to exactly the right height so the cylinder can turn. That means each cut on the blade has two measurements, where along the blade it sits and how deep it goes. Kwikset keys use seven depths spaced roughly 0.023 inch apart. Schlage uses ten depths only about 0.015 inch apart, which is why a sloppy cut on a Schlage key shows up faster. A key cutting service reproduces those measurements one of two ways. On a duplicator, a guide follows the original while a cutter wheel grinds the blank in step. On a code machine, we set each position and depth from numbers, so the machine never touches the original at all. Laser-cut keys, with their milled wavy track, need a different machine that cuts a groove rather than notches. Knowing which machine fits your key is the first decision, and it takes a minute of looking at the blade, the stamping on the head and the lock it belongs to.
Work included on a typical visit
- Tracing a good key on the duplicator. Plain residential keys that still look factory-fresh are ideal for tracing. We look at the cuts for rounding first, since a rounded valley is a sign of wear. If the key passes, we copy it. If it doesn't, we move to code cutting. Either way you hear the reason, not just the result.
- Matching the blank to the keyway. Blank choice decides whether a perfect cut still fails. Our van carries blanks for the common Kwikset, Schlage, Yale and Weiser keyways and the usual padlock profiles. When your key calls for something less common, we say so, order the correct blank and finish the job rather than forcing a near match.
- Laser-cut and track keys. That wavy track is made by a small spinning end mill, not a wheel, so the machine, the clamp and the blank all differ from a standard setup. Tolerances are tight, and a slightly off cut can feel fine in the keyway and still refuse to turn. We identify the profile first and quote honestly.
- Batch and bulk key cutting. Volume work lives or dies on consistency. A cutter that dulls halfway through a batch yields keys that drift from the first to the last. We check the cutter, spot-test keys at intervals and tag every key as it leaves the machine, so mix-ups don't happen in a drawer later.
- Keys cut from the lock itself. Decoding takes patience. For some locks, a specialized tool reads each position while the cylinder stays in the door. For others, we pull the cylinder and measure at the bench. Either way, the readings become a code, the code goes into the machine, and you end up with a working key.
Local factors in Ontario
Apartment keys are a tangle of tenants, managers, roommates and lease clauses about duplication. We cut copies for residents with the manager's permission where required, and for managers we handle unit-by-unit batches with clean labeling. If a building uses a restricted keyway, only management can authorize extras. For ordinary keys, we can usually cut and test at your door during the same visit.
Established neighborhoods are full of keys that have been copied for decades. Original hardware from Schlage, Kwikset and Yale, old mortise sets and the occasional warded lock produce keys with worn cuts and blanks that are hard to find. Around Edenglen, our key cutting service often cuts fresh keys by code rather than tracing tired ones, and we'll tell you honestly when an old lock is better replaced than copied.
Warehouses and yards run on batches: dozens of padlocks, gate chains, dock office keys, equipment keys and cage locks, with turnover among the staff who carry them. We cut in quantity, keep patterns separate and label by access level. Keyed-alike padlock sets help, since one key opens many locks. Restricted or fleet-issued keys need written authorization before we cut anything.
Situations this covers
- A property manager calls about a key stamped with a lock maker's name and Do Not Duplicate. She wants five more for an office suite near Toyota Arena. We'd ask whether she holds the authorization card, explain that the profile is controlled, and either start a proper order or tell her whom to call. A guessed copy is how a key control system leaks.
- Picture an older house in New Haven with an original warded lock and one flat steel key, pitted with age. Modern blanks won't fit. We'd look at the lock and tell the owner honestly whether a blank can be filed to fit or whether the cleaner answer is a new cylinder that takes an ordinary key. Both options get a plain price.
- For example, a landlord with a fourplex off Mission Boulevard books a key cutting service visit for eight copies of each unit key and four of the shared laundry room key. We'd cut each pattern from its best original, label the bundles by unit, and try one key from every batch in its door. The landlord leaves with a tidy bag per unit and a note listing which doors were checked.
- Consider three roommates in a rental near Graber Olive House who need copies of the apartment key. Their lease allows it, but the landlord asks to approve in writing. We'd wait for the confirmation, cut the keys at the curb, test each in the door and note the count on the work order. Without that approval, we would have stopped and explained why.
How the visit works
- Tell us what you have and what you need. A short call shapes the visit. Tell us if the keys are for a deadbolt, padlock, cabinet or mailbox, whether they're new or worn, and how many copies you want. If you have a key code or paperwork from the lock's packaging, mention it. We'll quote the job and confirm a time.
- Confirm who the keys belong to. Keys give access, so we ask about ownership or authority before cutting. For a home, a photo ID and a word about the address usually do it. For a business, a manager's authorization. For restricted keys, the authorization card or the signer on file. It takes a minute and protects the people who rely on those locks.
- Match the blank and choose the method. Matching the blank often means holding your key beside two or three near-identical candidates. We compare the groove pattern, test the fit in the keyway and sometimes in the lock, and only then clamp the blank in the machine. If we don't carry the right one, we say so and arrange an order.
- Set up the machine and cut. Different keyways reference from different places, some from the shoulder, some from the tip. We confirm which before clamping, because a key aligned to the wrong stop comes out with every cut shifted. Code machines handle this through position settings; duplicators rely on our eye and a test.
- Deburr, clean and compare. After cutting, the key isn't ready. We remove burrs along every edge, check the tip for a lip that could catch inside the keyway, and lay the original and the copy side by side to check each cut. This is where small errors get caught cheaply.
- Test in the lock and hand over. We don't hand over keys on trust. Each one is tested in your lock, and for a batch we test at least one key from every pattern in its door. You get your originals back, the copies in labeled bundles, and advice about which key to keep as the master.
How we quote the job
- How many keys, and how many patterns. Tell us the whole list when you call, not key by key. Ten copies of one key and one copy of ten different keys are very different jobs. A tidy list lets us bring the right blanks and give an accurate quote before the van leaves.
- Controlled and restricted profiles. Keys tied to a restricted system need paperwork before anyone cuts them. That can mean authorization from a facility manager or a factory order, which adds steps and often lead time. We tell you what a controlled key will involve before work starts.
- Travel, timing and extras. We drive to you from our San Bernardino base, so distance and drive time are part of the quote, along with the hour you call within our schedule. A visit that combines our key cutting service with another job, such as easing a sticky lock, spreads the trip across both.
Every job gets a clear quote before any work starts. Call (951) 903-3193 with the details and we'll tell you what to expect for your situation in Ontario.
What to do before we arrive
- Test your spare keys twice a year. Walk up to each lock with the spare instead of your daily key and run it through. Spares sit in drawers, and many turn out to be copies that never worked quite right. Learning that on a quiet Sunday beats learning it during a lockout.
- Keep oil sprays away from your locks. Common household lubricants leave a film that collects dust and gums the pins, especially in dry, dusty neighborhoods around Ontario. If a new key is stiff, a small puff of dry graphite or PTFE lubricant is the better choice. Still stiff afterward? The key or the cylinder needs attention.
- Cut copies from the original, never from another copy. Each generation adds a little error, and three or four copies deep you end up with a key that works only when the lock is feeling generous. Pick one key as the master, keep it unused in a safe spot, and make everything else from it.
- Save the little tag or card that came with new locks. Many manufacturers print a key code or keying number on it, and with that and the keyway we can cut a key with no original in sight. Tape it inside a closet or file it with your house paperwork, not on the key ring.
Mistakes to avoid
- Copying a copy. Each trace passes along the previous key's flaws and adds a few of its own. Several generations later the key hangs in the lock and nobody can say why. Go back to the original, or have a fresh key cut by code from the factory numbers.
- Bringing the wrong kind of key. Car keys, fobs, smart-lock cards and many alarm keys need programming, not just cutting, and they are handled on separate pages. If you're unsure what a key is, bring it, say what you want from it, and we'll point you the right way.
- Trusting a blank because it looks right. KW1 and SC1 blanks, among many others, are close cousins across a counter yet fit different keyways. A near match won't enter the lock or, worse, enters and jams. Always check the stamp on the bow and try the blank before cutting.

Frequently asked questions
Can I get a car key cut from you?
We can cut the metal blade of many car keys, but modern keys with transponder chips also need programming before they start the engine. That's covered on our car key pages, including car key cutting and replacement. This page is about house, padlock, cabinet and mailbox keys. If you aren't sure what your car key needs, call and give us the year, make and model.
Is it safe to send a photo of my key to get it cut?
It's risky. A sharp, flat photo can be enough to work out the cuts, so anyone who sees it can potentially make a copy. A photo also doesn't tell us the blank, the wear or the lock's real specifications. We recommend having a locksmith inspect the key in person, and we suggest not posting images of keys on social media.
How many keys can you cut in one visit?
As many as the job needs. Setup is per pattern, so large batches of one key go quickly, and mixed sets take longer because each pattern needs its own setup. There is no fixed limit, but tell us the count and the patterns when you call (951) 903-3193 so we bring enough blanks. Big batches get labeled and sampled in their doors.
Why does my new key go in but won't turn?
Usually one of three things: the blank is slightly wrong for the keyway, one or two cuts are a hair off, or burrs from cutting are catching the pins. Sometimes the original was worn and the copy inherited it. Don't force it. Call (951) 903-3193 and we'll check the key, find the problem and recut it on the right blank if needed.
When can you come to cut keys?
Julian's Locksmith works every day from 6:30 a.m. to 11:30 p.m. We are closed overnight, and we aren't a 24/7 service. Call (951) 903-3193, tell us what needs cutting, and we'll give you an honest arrival estimate and a price before we drive to Ontario.
What does a key cutting service actually do?
A key cutting service turns a blank into a working key by grinding cuts that match your original, a key code or your lock. Done properly, that includes matching the blank to the keyway, cutting on a correctly set machine, removing burrs and testing the key in the lock. Julian's Locksmith does this at your door in Ontario and quotes the job before we start.
How far is Ontario from your base?
Ontario is about 25 miles from our San Bernardino base, roughly 33 minutes in light traffic. Arrival time depends on traffic and on the job the technician is finishing, so we give you an estimate on the phone before you commit.
