High Security Key Duplication in Fontana: Angled, Dimple and Sidebar Keys
Short answer: Some high security keys can be cut in one visit; others must be ordered from the maker, which takes days rather than minutes. We tell you which applies before you commit, and we never copy from a photo. Julian's Locksmith works every day from 6:30 a.m. to 11:30 p.m. Call (951) 903-3193 for Fontana.

You hold a key that doesn't look like the others on your ring: heavier, maybe with round dimples in its face, angled cuts or a groove down one side. You asked a hardware-store kiosk for a copy and got a shrug, or worse, a key that almost works. High security key duplication in Fontana is a different craft from ordinary key cutting, because the lock behind it was built so casual copies can't happen. Julian's Locksmith starts by identifying what you have, then tells you honestly whether we can cut it on the van, order it through the maker, or send you to the dealer who holds your records. Call (951) 903-3193.
High Security Key Duplication in Fontana: what to expect
Sometimes a copy is the right answer and sometimes it's a distraction. If you simply need another key for someone authorized, high security key duplication is the straightforward path. If a key has been lost, stolen or kept by a former employee or tenant, a copy of what remains does nothing about the one that's out there; the real fix is rekeying or replacing the cylinder so the missing key no longer works. If your system is old or discontinued, converting to a current cylinder may serve you better than another copy of an aging key. And if the door itself is weak, the strongest cylinder in Fontana still leaves you with a hollow door and a thin strike plate. We talk through those options when we see them, then quote what you asked for. Think of a high-security key as one part of a plan: the lock, the key control and the door each need to be as serious as the others.
Work included on a typical visit
- Dimple and telescoping-pin keys such as Mul-T-Lock. A dimple key doesn't wear along an edge, it wears inside each dimple, so a worn key can look fine and still drift. We measure dimple depth against the chart and often cut from code rather than from the original. Newer versions also carry a movable element in the head, which has to be reproduced.
- Sidebar keys such as Schlage Primus and Everest. Many Schlage Everest and Primus systems are controlled, so blanks aren't sold over the counter. Whether we can cut your key depends on the registration. We look at the key, tell you which system you have, and explain how a copy is released for your account.
- Disc-detainer and multi-surface keys such as Abloy and ASSA. ASSA and related systems add secondary cuts or sidebar elements, so one pass on a standard machine can't reproduce them. We examine your key to see how many surfaces are cut and tell you honestly whether we can make the copy on the van or need to order it.
- Keys cut from code or registration records. A key cut from code starts from the specification rather than from a used key, so it's the cleanest source for a copy. We can't invent a system's code from nothing: the registered owner or the dealer holds it, and we work with whatever documentation you have.
- Testing across the whole cylinder set. A copy that opens one cylinder may not open the next. If your key works several locks in a keyed-alike or master-keyed system, we test it in more than one. A key that works in only some cylinders is within tolerance for those and fails the rest.
What's different about Fontana
Warehouses and distribution sites around Fontana often protect cages, tool rooms and offices with high-security padlocks and cylinders. Shift changes make high security key duplication and key accountability harder. We cut keys for supervisors from your authorized list, number every copy, and suggest key levels so a night-shift key doesn't open the whole building. If the maker must supply blanks, we order ahead. Clear numbering saves hours when an audit comes.
Some older homes in Fontana now carry a modern high-security cylinder on the front door or a gate while the rest of the hardware dates from decades ago. The new cylinder's keys are precise, but the old door and strike may be the weaker link. When we copy a key we also glance at the frame and strike plate, and mention reinforcement if we see a gap.
Gated communities and HOA clubhouses in Fontana use high-security keys for amenity rooms, pump houses and gate controls. Board turnover means paperwork gets lost. We help the current board identify the system, confirm who may order, cut or order copies for staff and vendors, and number everything so the next board inherits a working key list. A short written log passed along at each election keeps the system from being rediscovered every few years.
Situations this covers
- A landlord arrives with a high-security key that was bent in a deadbolt and hammered straight. Copying from it would carry the distortion into every new key. We'd decline to trace it, check which cuts are still intact, cut from code, and take the damaged key off her ring before it breaks inside the lock.
- A clinic in Fontana keeps controlled supplies in a locked closet behind a high-security cylinder. The office manager needs a third key for the new nurse lead, and policy requires a log. We'd confirm the clinic's authority, cut or order the key, stamp it with a number and test it in the cylinder while she watches.
- A condo board treasurer asks for six copies of a Medeco key for the storage room and expects them by evening. We'd explain that Medeco blanks are controlled, confirm the board's authority, and place the order through the proper channel, giving her the real wait up front instead of letting her count on the afternoon.
- At a family property in North Fontana, three adult children each want a key to the pool house gate, which uses a dimple padlock. Their father holds the only key and doesn't want to lend it for a week. We'd cut copies on site while he keeps the original in view and hands it right back.
From your call to the finished job
- Show us the key and what it opens. Photos of both sides of the key and the lock face save time. Please don't read us a code from memory or send a measurement; we need the key itself in hand for the cut. The photos just help us arrive with the right blanks and cutters.
- Confirm who holds the authority. We hold California locksmith license LCO7891 from BSIS and verify identity before making any key. For controlled systems that is only the first step: the registration decides who may order, and we won't work around it.
- Inspect and measure the original. Before any metal is cut, we compare the key with a known-good blank of the same family for thickness, width and shoulder. A blank that is subtly wrong cuts a key that almost works, and almost is the worst outcome in a precision cylinder.
- Choose the route: cut on site, order, or refer. The route depends on the system, not on how much we'd like to finish today. We tell you which one applies, how long an order is likely to take in days rather than minutes, and what you'd need to supply for each.
- Cut, finish and compare. When we cut from code, the original sits aside as a comparison rather than a source. We check the new key against it feature by feature, and if the original proves worn we tell you by how much, so you can decide whether to retire it.
- Test, number and hand over. We stamp or tag each key with a number, not a name, and leave a short note of what was cut and from what source. For businesses, that note belongs in your key log with the date and the person who received the key.
What affects the cost
- How complex the cut geometry is. Tell us what you see on the key and we'll give you a realistic idea on the phone. Dimples on a plain blade are one kind of job; angled cuts with a milled side groove are another. We confirm the final figure once we've handled the key itself.
- How many copies, and at which key level. The first key carries the setup and inspection. Additional copies of the same key go faster. Master-keyed systems add complexity because each key level has its own specification and its own authorization. If you expect to need several, ordering them together keeps the per-key effort down.
- Timing, order lead time and the visit. We work every day from 6:30 a.m. to 11:30 p.m. A factory order placed late on a Thursday won't move until the maker is open, so plan ahead if you need keys by a particular date.
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 Fontana.
Advice before you book
- Use dry lubricant sparingly. Oil attracts grit, and tight-tolerance cylinders such as dimple and sidebar types hate grit. A light PTFE-type lubricant once or twice a year helps. In dusty seasons in Fontana, wipe the key as well as the lock.
- Order spares when the lock is installed, because high security key duplication by factory order takes days, and an installer can include extra keys in the same order. Waiting until the last key is the only key is how a simple spare turns into an urgent one.
- Photograph the head of the key, front and back, and the face of the lock today. Brand names, patent marks and series numbers are the quickest way to identify the system, and a photo is easier to find than a drawer search on the day you need high security key duplication.
- Stamp keys with numbers, not names. A number lets you track who holds which key without telling a stranger what it opens. Keep the list in your records, never on the key ring or on the tag. If a key is ever found, a bare number points nowhere.
Mistakes to avoid
- Treating high security key duplication as the fix for a lost or stolen key. A spare doesn't take the missing one out of circulation. If a key might be in the wrong hands, rekey or replace the cylinder and issue new numbered keys.
- Copying a copy. Each generation drifts, and angled cuts and dimples hide drift better than a simple pin key does. By the time the key feels wrong, it has already worn your cylinder, and it is easy to trust a key that looks fine. Cut from code or from the best remaining key.
- Assuming high security means impossible to copy. Some profiles are controlled and some are not, and protection varies by maker and age. Ask what your system actually carries today rather than relying on the label. A label is marketing; a registration is protection.

Frequently asked questions
A former employee still has a key. Should I copy the ones we have?
Copying the keys you have won't take the missing one out of circulation. The reliable fix is rekeying or replacing the cylinder so the old key no longer works, then issuing new numbered keys. We can usually do the rekey and cut the new keys in one visit when the system allows it.
Do you copy Mul-T-Lock keys?
We can often copy unrestricted dimple profiles, and we say plainly when a Mul-T-Lock key is controlled and must come from the maker or a registered dealer. Newer keys carry a movable element in the head that has to be reproduced too. Show us the key and the lock face, and we'll tell you how your copy would be made.
Can you make a copy from a photo of my key?
No. A photo can help us identify the system, but it can't give us accurate cut depths, angles or side milling. We work from the key in hand, from a documented code, or from the factory's own records. Anything else risks a copy that doesn't work and can scrape the cylinder it is tried in.
How long does high security key duplication take?
If we can cut your key on the van, the copy happens during the visit, along with inspection and testing. If the maker must supply the key, the order takes days rather than minutes, and sometimes longer for unusual profiles. We give you an honest estimate before you commit and never order anything until you've approved it.
I rent my home. Can I copy my high security key?
Probably not without your landlord. The lock belongs to the property, and the registration is usually in the owner's or manager's name. We would need their approval, and many leases restrict key copying. A short message from the landlord or manager lets us proceed when authority is clear; if it isn't, we explain who to ask.
Can a hardware store copy a high security key?
Almost never. A kiosk machine traces straight cuts at a single angle, while high security keys use angled cuts, dimples, side grooves or discs, and many blanks aren't sold over the counter. Some stores refuse; others cut a key that almost works, which can scrape the pins and sidebar inside your cylinder. In Fontana, start by showing us the key, and we'll say what route a copy will take.
How far is Fontana from your base?
Fontana is about 16 miles from our San Bernardino base, roughly 22 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.
