High Security Key Duplication in Pomona: Copies Cut to Spec
Short answer: Bring the working key, photo ID, and any registration card or paperwork that came with the lock. Many high security systems release spares only to the registered owner or an authorized signer, so we confirm authority before cutting. If we can't be the right source, we say who is. For businesses and rentals in Pomona, the account holder or property owner usually has to approve.

Not every key that looks serious is high security, and not every high security key is copied the same way. A few can be cut on a specialized machine in our van. Some profiles are controlled, so blanks come only from the maker. Others can only be released by the dealer who registered your system. Julian's Locksmith offers high security key duplication in Pomona with a straight answer on which path yours takes, how many days an order might need and what paperwork you'll supply. You decide whether to go ahead before anything is ordered or cut.
High Security Key Duplication in Pomona: what to expect
There are three honest routes to a copy of a high-security key. The first is cutting on site. When your system uses an unrestricted profile and we hold the correct blank and cutter, we can make the copy at your door in Pomona, inspect it under magnification and test it before we leave. The second is a factory order. When the maker controls the blank or the cut, we place the order with the right authorization and the key arrives cut to your system's specification, usually after days rather than minutes. The third is referral: if the dealer who registered your system holds the records and the right to release keys, we tell you who that is and why we can't bypass them. Knowing which route applies is the first thing we work out, and we say it before anything is ordered or cut. If you're hoping for a same-visit copy, ask us about the system first. We would rather disappoint you honestly on the phone than waste your afternoon at the door.
Work included on a typical visit
- Identifying the system from the key in your hand. Many owners don't know what lock they have, but the key often tells us. We read the headstamp, measure the blade thickness, count cut positions and look for secondary tracks. That identification decides which machine, blank and authorization a copy needs, and we explain it before quoting.
- Dimple and telescoping-pin keys such as Mul-T-Lock. Dimple keys turn up on higher-end residential doors and gates as well as commercial cylinders. If your key has dimples in its face, tell us the brand and whether it came with a card. That decides if we cut it on the van, order the blank, or send you to the registering dealer.
- Disc-detainer and multi-surface keys such as Abloy and ASSA. Keys for disc cylinders often show up on padlocks, gates and industrial equipment rather than on house doors. Bring the key and the lock if you can. The padlock body often carries the brand and series, which saves time identifying the system.
- Worn, rounded or slightly bent high-security keys. If your high-security key has started to feel notchy, the key and cylinder may be wearing together. We test a corrected copy. If it feels the same in the lock, the cylinder is the worn part, and we discuss servicing or repinning it before cutting more keys.
- When a copy is the wrong fix. Sometimes owners want a spare because their system is aging, with a discontinued keyway, a cylinder rattling in the door or a key that's no longer available. Then converting to a current high-security cylinder with new keys can be a better use of money than another copy.
What's different about Pomona
Student housing near California State Polytechnic University rarely has high-security keys on bedrooms, but landlords sometimes use them on shared utility rooms or on a master-keyed building. Turnover is constant. Property managers should copy keys through an authorized channel, number every key, and plan to rekey when a number goes unreturned. We help owners build a simple issue-and-return routine. Even a one-page log makes next summer's turnover calmer.
Some older homes in Pomona 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.
Apartment buildings in Pomona seldom use high-security keys on individual units, but they do on laundry rooms, equipment closets, roof access and management offices. Managers need spares for maintenance staff and vendors. We confirm the owner's authority, copy the keys, number them and update the property's log, so the question of who holds a roof key has an answer. It is a small record that settles arguments later.
Example situations
- An executive assistant at a firm near SR-71 needs two more keys for the partners' conference room but has only one in her desk. The key is a worn dimple type. We'd cut a clean reference key by code, make the second from it, and record the key numbers on the firm's sheet, along with who received each one.
- A clinic in Pomona 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.
- At a family property in Spadra, 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.
- A typical call: an office manager in Pomona inherits a Medeco deadbolt on the supply room, one key in the drawer, and a new assistant starting Monday. The hardware-store kiosk refused to touch it. We'd identify the system, check who is authorized to order, and explain whether the copy can be cut on the van or has to come through the maker.
How the visit works
- Show us the key and what it opens. Call (951) 903-3193 for high security key duplication and describe the key: brand names, a patent mark, dimples, angled cuts or a groove on the side of the blade. Tell us what it opens and whether you have a card. We can often narrow the system before we head to Pomona.
- 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. Under good light and magnification we check each cut, dimple or notch for rounding, burrs and bends, and measure against the system's depth chart. If the key has drifted out of specification, we plan to cut from code instead of copying it.
- Choose the route: cut on site, order, or refer. Where factory ordering applies, you get a clear list: what we're ordering, what authorization goes with it and what happens when it arrives. You decide whether to proceed, and nothing is ordered until you've agreed.
- Cut, finish and compare. A high-security cut leaves tiny burrs that scrape pins and sidebars. We finish the key carefully and check it with a gauge before it goes near your cylinder. Skipping that step is how a good blank becomes a worn lock.
- 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
- Where the blank comes from. Uncontrolled blanks for common high-security profiles are easy to stock and relatively inexpensive. Controlled blanks come only from the maker or authorized dealers, with their own pricing and paperwork. We tell you which group your key falls into before you commit.
- Original key, code or neither. A copy made from a sound original is the straightforward case. If the original is worn, a code-based cut takes more because we have to obtain or confirm the specification. If you have neither, a new key means working from the cylinder, and that's a larger job.
- 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.
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 Pomona.
What not to do
- 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.
- 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.
- Using a bent or straightened key as the source. Straightening a high-security key can leave hidden distortion in the blade or side groove, and every copy inherits it. Retire the damaged key and cut from the specification instead. A key that was ever bent deserves suspicion.
What to do before we arrive
- Keep a simple key log even at home: three or four lines on who has which numbered key and when it was issued. It takes five minutes, and it makes a later decision about rekeying much easier. Update it whenever a key changes hands, even briefly.
- Don't lend your only high-security key to anyone for high security key duplication elsewhere. The key leaves your sight, you can't verify the blank, and you may learn later it was copied somewhere that shouldn't have done it. Have the copy made in front of you.
- Keep one spare off site, with a trusted person or in a secure box. A fire or break-in that takes your keys shouldn't leave you waiting on a factory order while the door is compromised. Tell that person what the key opens and not much more.
- 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.

Frequently asked questions
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 Pomona, start by showing us the key, and we'll say what route a copy will take.
Can you copy a Medeco key?
Sometimes. Medeco keys carry angled cuts, and many blanks are controlled, so the answer depends on your system and who is authorized to order. We inspect the key, confirm authority, and then either cut it where our equipment and the blank allow or order it through the proper channel. We tell you which route applies before anything is cut or ordered.
What is the difference between a duplicated key and a key cut by code?
A duplicate follows an existing key, so it inherits that key's wear. A code cut starts from the system's specification, such as the bitting from your records or the dealer, and produces a key to factory specification. For worn high-security keys we prefer code cutting. The catch is the specification itself, which only the registered owner or the dealer holds.
Do I need my registration card?
Bring it if you have it. A card, or the dealer's name on your paperwork, can turn a long search into one phone call, and many systems release spares only to the registered owner. If you don't have it, we can still identify the system and tell you which steps remain open, including contacting the dealer or moving to a cylinder you control.
What hours do you offer high security key duplication?
We work every day from 6:30 a.m. to 11:30 p.m., and we're closed overnight. Factory orders ship when the maker is open, so plan around that if you need keys by a date. Call (951) 903-3193 and we'll give you a realistic timeline for your Pomona address.
Why does a high security key cost more than a regular one?
High security key duplication costs more because proprietary blanks cost more, the cutting takes more setups and inspection, and controlled systems add paperwork and handling. A single row of dimples is simpler than angled cuts plus a slider. We quote after seeing the key, and the number we give you before work begins is the number we expect to bill unless the job changes on site.
How far is Pomona from your base?
Pomona is about 32 miles from our San Bernardino base, roughly 38 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.
