Ontario High Security Locksmith: Who to Hire and What to Ask
Short answer: Before you hire anyone in Ontario, ask three things. What is your California locksmith license number, and does it check out at search.dca.ca.gov? Which patented systems do you actually install, and who holds the key registration afterward? What happens if I'm locked out of one of these cylinders? Straight answers separate specialists from advertisers. Ours: LCO7891, systems explained on the phone, registration in your name.

Most people call a high security locksmith after something happens. A back door was forced at a shop on Vineyard Avenue. A manager left on bad terms and kept a key. A tenant moved out with three copies nobody can account for. Others call beforehand, because an insurer asked about the locks, a new lease came with a suite full of unknown keys, or a pharmacy, dental or jewelry operation needs a stricter standard. In every case the useful first step is the same: someone who knows the products walks the doors with you and ranks the weak points. Julian's Locksmith does that survey in Ontario, then quotes the work before anything is ordered.
What to know first in Ontario
There's a simple way to separate specialists from generalists: listen for specifics. Ask a high security locksmith what they would put on a glass storefront door versus a steel back door, and you should hear cylinder formats (mortise, rim, profile, interchangeable core), cams or tailpieces, and a view on the strike and frame. Ask about key control and you should hear about patented blanks, authorization records and who may request copies. Ask about the license and you should hear a number you can look up. Julian's Locksmith holds California locksmith company license LCO7891, issued by the Bureau of Security and Investigative Services, and you can verify it at search.dca.ca.gov. Also listen for restraint. Specialists say 'it depends' more often than salespeople do, and they give reasons. They'll tell you when a mid-range Grade 1 deadbolt is enough, when a restricted keyway without full patent protection fits your budget, and when to save premium cylinders for the two doors that carry real risk. In Ontario, that candor is usually worth more than any brochure.
How we can help in Ontario
- Security surveys and written specifications. A survey is not a sales pitch for the priciest lock. We note which doors carry real risk, which are fine with a better deadbolt, and which need frame work before any cylinder upgrade makes sense. Afterward you receive a plain-language list with the reasoning, ready to approve in stages if your budget calls for it.
- Bench service and repinning. Patented cylinders can be serviced, not just swapped. We disassemble, clean, inspect springs and sidebars, and repin to a new key combination when a key walks away, often keeping the same cylinders and hardware. Repinning is a legitimate alternative to full replacement, and we explain where it does and doesn't apply.
- Opening and recovering high security locks. Lockouts on patented hardware take longer than on builder-grade locks, and that is the lock doing its job. We verify ownership first, then work the cylinder methodically. When drilling is unavoidable, we aim for the exact point that spares the door, then fit a replacement cylinder so the opening is secured on the same visit when parts allow.
- Master-keyed high security systems. Yes, high security cylinders can be master keyed, with caveats. Some product lines support multi-level master systems, others restrict them, and added complexity can trade away some pick resistance. We design the hierarchy with you, explain the limits and document the keying chart so future additions follow the plan.
- Re-securing after a break-in or key loss. When a ring of keys disappears, change the lock rather than worry about it. Registered high security keys make this faster: the system record tells us the exact cylinder and combination, and we can repin or replace on a short timeline. Outside our hours, secure the door temporarily until we open.
Local factors in Ontario
Newer tracts in Ontario are typically fitted by the builder with serviceable but common locks, and every home in a development may share the same keyway family. A high security locksmith fits patented or restricted cylinders to the doors that matter, adds a reinforced strike where builders used short screws, and issues keys that contractors can't copy. Do this early, before painters, movers and landscapers have each taken a copy.
Strip centers along Holt Boulevard share rear service corridors, roll-up doors and cash handling routines. A high security locksmith there looks at the back door first, because that is where owners tend to be most exposed. We pair a reinforced steel door and a patented cylinder with a separate key for the cash office or stockroom, and we set simple rules about who closes and who holds the master. Landlord approval is common, so we ask early.
Homes built decades ago in Ontario often have original deadbolts, mortise sets and wooden frames that have shrunk and cracked. A high security locksmith evaluates whether a patented cylinder can fit the existing hardware, but the real gain often comes from replacing worn locks, installing long strike screws and straightening doors that no longer latch cleanly. Patented keys are a bonus once the structure is sound, particularly for a detached garage or workshop.
Situations this covers
- For example, a dental practice near ONT Field keeps controlled medications in a wall cabinet and a back storeroom. A hygienist left last month and nobody can say how many keys she carried. A high security locksmith skips the guesswork: we repin the two storeroom cylinders, issue numbered keys to current staff and set a short authorization list for future copies. The front door stays as is, because the survey showed it was never the weak point.
- A condo board near Ontario Mills discovers that contractors kept copies of the keys to the pool equipment room and the electrical closet. Blanks for that keyway are sold everywhere. We propose a restricted, registered keyway for those two rooms only, issued against signatures to the treasurer and the management company. Residents' unit doors stay untouched, and the board gets a short list of who holds what.
- A manager at a small medical clinic inherited a master key system from the previous tenant and has no keying chart. A high security locksmith can't read minds but can read cylinders: we pull samples, decode the pinning and reconstruct the hierarchy so you know which keys open what. Then you decide whether to keep, extend or replace it. That is a survey job, not an emergency, and we schedule it that way.
- A homeowner in Edenglen bought a custom house whose previous owner installed premium locks. The keys say Medeco, the owner card is gone and the seller can't be reached. We confirm who you are with your closing documents, identify the cylinders from their faces, ask the manufacturer's channel whether the registration can be transferred and, if it can't, quote a clean new system instead of leaving you guessing.
How the visit works
- Tell us what you're protecting. Call (951) 903-3193 and describe the property, the number of doors and what prompted the call. A break-in, a departing employee and a lease renewal lead to different plans. The more you share, the better we can prepare for the survey visit.
- Confirm who can authorize the work. Business tenants sometimes need landlord consent before cylinders change. We ask early so the survey doesn't stall. A short email from the property manager, or a lease clause, normally settles it, and we keep a copy with your system documentation.
- Survey the doors, hardware and keys. We also inventory keys and users. Surveys often uncover surprises, such as three doors on one key, an unmarked master or a cylinder that has already been drilled. Knowing the real state of your system keeps the quote honest.
- Specification, quote and order. Quotes list the work in stages so you can approve what matters most first. A typical split is door and frame repairs now, patented cylinders when they arrive and the key control paperwork alongside. We explain every line in plain language.
- Install, reinforce and key. Installation covers the details: cams matched to the lock, set screws tightened, long screws into the framing and cylinder guards seated flush. We cycle each lock many times from both sides and check that the door closes and latches without effort.
- Hand over keys and records. You receive keys, the owner or registration documents, a record of what was installed and a one-page summary of how to order more. We suggest storing the documents apart from the keys, ideally in a locked cabinet or off-site.
Pricing factors
- Number of doors and cylinder formats. Every opening adds parts and labor, and formats differ. A mortise cylinder, a rim cylinder, a padlock and an interchangeable core each carry their own price and fitting time. We count openings and formats at the survey so the quote reflects your real property.
- Door and frame condition. A high security cylinder in a weak door is money wasted. If the frame needs a new strike reinforcement, a jamb repair or a replacement door, we say so, give you the choice and explain what the cylinder alone would and wouldn't achieve.
- Special order timing and temporary securing. Scheduling matters too. We work every day, 6:30 a.m. to 11:30 p.m. Planning installation inside those hours and combining it with other work keeps trips, and therefore cost, down. Restricted keyways can mean ordering parts ahead of time, so tell us early what you have in mind and we can plan the visit around delivery.
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.
Advice before you book
- Treat stamped 'Do Not Duplicate' markings as a request, not protection. Many kiosks and some stores will still copy such keys on standard blanks. Real control comes from a patented or restricted keyway where blanks can't be bought freely, plus an authorization record. If your keys are ordinary, plan on upgrading the cylinder.
- Plan for the hours we're not open. Julian's Locksmith works every day from 6:30 a.m. to 11:30 p.m. and is closed overnight. Keep your alarm company's number, a property-patrol contact and a temporary securing option such as a door bar on hand for the overnight hours.
- Decide your spare key count before installation. Ordering patented keys later requires authorization and shipping, while ordering extras with the first cylinders is faster and simpler. Think about who truly needs a key, then add one sealed spare stored off-site. More keys means more risk, not more convenience.
- Walk your own property at dusk and try each door as a stranger would. Look for glass within arm's reach of a handle, gaps between double doors, exposed hinge pins and strikes held by short screws. Most findings cost little to fix, and a specialist will focus the survey on the worst ones.
What not to do
- Assuming a heavy lock is a high security lock. Weight, brass finish and Grade 1 durability say nothing about picking, drilling or key copying. Ask which listing or standard the cylinder meets, and whether keys are patent-protected. If the answer is vague, you're probably looking at a good ordinary lock.
- Hiring on the first ad that says 'high security.' Many ads are lead generators that dispatch whoever is available, with no particular skill. Ask for the company name, license number and the specific systems they install before agreeing, and don't pay a deposit to someone who can't answer.
- Skipping the key log. Without a record of who holds which key, you can't tell whether a departing employee's key matters, so you either ignore the risk or replace everything. A one-page log costs nothing and makes every later decision easier.

Frequently asked questions
Can you work on a system someone else installed?
Frequently, yes. We identify the product line from the cylinder faces, check whether the key registration can be reached, and then service, repin or extend the system. Some situations need the original dealer or the factory, particularly when an owner card is missing. We explain what's possible after we see the hardware, and we quote a fresh system if the old one can't be recovered.
Are you licensed, and how do I verify it?
Yes. Julian's Locksmith holds California locksmith company license LCO7891, issued by the Bureau of Security and Investigative Services under the Locksmith Act. Anyone can verify a license at search.dca.ca.gov by searching the license number or company name. We encourage you to check before we arrive, and we'll give you our full business name when you call (951) 903-3193.
Can you open a high security lock if I'm locked out?
Often, but not always without damage. We verify ownership, then try picking, decoding or a manufacturer procedure. Some high security cylinders are designed to resist these methods, in which case drilling and replacing the cylinder may be required. We explain the likely outcome before starting so you can decide. Tell us the brand on the cylinder when you call so we can bring the right tools and parts.
Which high security systems do you work with?
We work with the major patented and restricted lines used in homes and businesses, including Medeco, Mul-T-Lock, ASSA and Schlage Primus, along with Abloy-style disc cylinders in many formats. Availability and ordering terms vary by manufacturer. When you describe your doors, we confirm which line fits and whether any restriction affects ordering, and we say so honestly if another source would serve you better.
Can you set up a key control program for my employees?
Yes. We design a program sized to your business: numbered keys, an issue log with signatures, a short list of people who may authorize copies, and a plan for rekeying when someone leaves. Combined with a patented or restricted keyway, it keeps copies from appearing unnoticed. We document the system and explain how to maintain it, then adjust as staff change.
Does my home need a high security locksmith?
Probably not for the front door. A Grade 1 deadbolt, long strike screws and a solid frame stop most attacks, and we'd tell you that at the survey. A high security locksmith makes sense when you store firearms, valuables or records, run a home business, or have many keyholders such as staff and contractors. In those cases, selective patented cylinders can add control for relatively little.
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.
