High Security Lock Installation in Pomona: Surveyed, Fitted, Keyed and Registered
Short answer: High security lock installation means fitting pick-, bump- and drill-resistant cylinders or deadbolts with patent-protected keys, then keying them and handing over a registered key set. In Pomona, Julian's Locksmith surveys the door, orders hardware that fits, installs and reinforces it, and tests every key. Many lines are special order, so expect a survey visit first. Call (951) 903-3193.

Did you buy a Medeco, Mul-T-Lock or ASSA deadbolt online and now wonder who can put it in? We can often help in Pomona, with a few honest caveats. Before drilling, we check that the product is genuine and fits your door, because marketplace listings sometimes mix up models, backsets and finishes. We also ask how its keys are sourced. If the manufacturer won't release more blanks for it, you'd own a lock whose key control exists only on paper. When everything checks out, we install and reinforce it properly. When it doesn't, we say so before we start.
High Security Lock Installation in Pomona: what to expect
A high security cylinder defends the lock face; the door and frame defend everything else. During installation we reinforce the strike and jamb, add a box strike or plate where the frame is weak, drive long screws into the stud and, on outswinging doors, add hinge protection and a latch guard. Codes shape the work as well. Residential entry doors need to open from inside without a key, so a double-cylinder high security deadbolt is generally not suitable on a home's main exit. Commercial exit doors must stay free to operate. Fire-rated doors carry a label, and field drilling on them is restricted, so on a rated door we work within the existing prep. We finish by testing: full bolt throw, no free play in the cylinder, a clean turn with every key and a check that the door latches on its own. In Pomona, that final round of checking is what turns a pricey lock into a protected door.
What we can do on-site
- Mortise cylinders for storefronts and older locks. Adams Rite-style storefront deadlocks use a mortise cylinder, and many shops still run the plain one that came with the door. Swapping in a patented cylinder with a free-spinning guard turns an easy target into a slow one. The work happens at the door, usually in one short visit once the parts are here.
- Rim cylinders and exit device trim. Rim cylinders sit on the inside of the door and connect through it to a rim lock, night latch or exit device. High security rim cylinders use the same mounting, so installation means removing the old one, setting the tailpiece for your device and tightening the mounting screws evenly.
- Interchangeable cores with high security keyways. Not every core housing accepts a high security upgrade. Large-format and small-format cores differ, and a few older housings need replacing. We identify what you have, tell you what's possible and quote the full change if needed. Once installed, a core system gives you flexibility that plain cylinders cannot.
- Padlocks, hasps and gate or roll-up door locks. High security padlocks use shrouded bodies and hardened shackles, and they resist the bolt cutters and pick tools that defeat common padlocks. We install them with through-bolted hasps that use concealed fasteners, so thieves can't back the screws out. They suit gates, sheds, trailers and roll-up doors.
- Installing hardware you bought yourself. If you've already bought a high security lock, we can usually install it. First we check that the model fits your door, that it's genuine and that its keys can be reordered. If something is off, we say so before drilling. When it checks out, we install, reinforce and key it like any other.
What's different about Pomona
Clinics and offices near hospitals in Pomona protect medication storage, patient records, supply rooms and after-hours entrances. We install high security cylinders on those doors, reinforce strikes and record who may authorize keys, the kind of control many practices want on paper. Fire-rated doors and required exits limit what we can drill, so we work within the existing prep and keep egress free.
Apartment buildings in Pomona rarely upgrade every unit door, and they shouldn't. The best use of high security lock installation is on shared and sensitive doors: mail rooms, laundry rooms, roof and utility access, offices and trash enclosures. We install patented cylinders there, tie the keys to a log and coordinate timing so no door sits unlocked. Unit doors can stay on rekeyable locks with strong strikes, which is easier to manage at turnover.
Landlords and property managers near campus in Pomona deal with annual turnover, many keys and tenants who copy them. High security lock installation on shared doors, owner storage rooms and utility closets keeps those keys from multiplying. Unit doors typically use rekeyable locks, and a patented cylinder on the building's main entry and mechanical rooms offers a good balance of cost and control.
Situations this covers
- A software start-up in a business park has a server closet behind a standard door with a standard lock. The founder wants access limited to three people. We install a high security cylinder in the existing lockset, add a hardened strike and number the keys. Should the company add electronic access control later, a low-voltage contractor handles the wiring.
- An estate owner has a wine room off the kitchen and a housekeeper who rightly has the house key. We fit a patented deadbolt on the wine room door, with a separate keyway from the main house system, and replace the original hollow door with a solid-core slab. The owner keeps two keys, one on the ring and one in a safe.
- A phone repair shop in a strip center has an aluminum storefront door with a narrow-stile deadlock and the original cylinder. After a break-in down the row, the owner wants something harder to attack. We install a patented mortise cylinder with a free-spinning guard, check that the deadlock throws fully into the frame, and confirm the inside exit stays free.
- A 1950s home in North Pomona has a mortise lockset on the front door, original and attractive. The owner wants to keep it. We remove the old cylinder, clean and test the lock body and fit a high security mortise cylinder in a matching finish. The door looks unchanged, while the keyway no longer opens to a kiosk copy.
How the visit works
- Talk through what you need to protect. We start with your reasons: lost keys, a former employee, valuables in a room or a recent break-in nearby. That tells us which doors matter and what kind of key control you need. We'll also ask who has keys now, because the answer often shapes the whole plan.
- Verify ownership and who may order keys. Because patented keys depend on a record of authority, we establish it early. Owners show ID and proof of the address, tenants bring the landlord's written approval, and businesses name an authorized contact. We note this in your key record, so a future copy request has a clear answer.
- Survey the door, lock and frame. On site we identify every lock format: deadbolt, mortise, rim, core, padlock. We note each door's swing, material and condition and write a parts list. If a door can't take the upgrade, we tell you now and price the alternative, so the order covers only hardware that fits.
- Specify, quote and order the hardware. You receive a written quote naming each product, where it goes, the key plan and the work on the frame. Once you approve, we order the hardware. Special-order timing varies by product, and we give you an honest estimate rather than a promise that shipping could break.
- Install, reinforce and key. We mount hardware in the right order: frame and strike first, then lock body, then cylinder. That sequence lets us adjust the strike to the bolt and keeps the cylinder free of dust and drilling debris. We tighten screws in stages and check for binding as we go.
- Test, register and hand over. Final checks cover alignment, free spin on guards, smooth key action and a full-force push on the closed door. We then hand over keys, explain the registration process and recommend where to store the owner record. A good installation ends with you knowing exactly who can order copies.
What affects the cost
- Which product line you choose. A cylinder with a UL 437 listing costs more than an unlisted one for a reason: it passed timed attack tests. The tier you pick shifts the quote more than anything else. We recommend based on what you're protecting, not on the most expensive page in the catalog.
- Cylinders, formats and quantity. Mortise cylinders, rim cylinders, deadbolt cylinders and cores are priced differently, as are padlocks and hasps. A mixed property usually needs several parts and a few extra measurements. We total these in one itemized quote, and larger orders often share setup time and travel across doors.
- What the door and frame need. A solid steel or wood door with a sound frame needs only the lock. A hollow-core door, split jamb or sagging hinge side needs repair or replacement, or the new hardware won't deliver. We assess the frame at the survey and price any prep, reinforcement or repair as a separate line.

Mistakes to avoid
- Buying from unknown marketplace sellers. Counterfeit or gray-market locks may look right but arrive with no listing, no key control and no way to reorder keys. Buy through channels that support the product, or ask us to confirm a purchase before you pay.
- Skipping the authorization record. If nobody knows who may order keys, you can't reorder them, and the system either stalls or leaks. Name the authorized people at installation, store the record apart from the keys, and review the list whenever staff or tenants change.
- Assuming cylinders are universal. A patented cylinder has to match the lock body's format, length and cam. Buying one by brand name alone can leave you with a part that doesn't fit. Have the lock identified at a survey, and order the exact size for each door.
Practical tips before you call
- Lubricate sparingly. Tight-tolerance cylinders do best with a dry lubricant, such as graphite powder or a PTFE spray made for locks. Oils and general-purpose sprays collect dust, especially in inland heat. If a cylinder starts to feel gritty, call us instead of flooding it.
- Ask for the exact model and its listing in writing. 'High security' on a box can mean many things. A quote that names the model and states its UL 437 or BHMA A156.30 listing lets you verify the claim with the manufacturer and keep the paperwork with your records.
- Tell us your door thickness and style. Most residential entry doors are about an inch and three-quarters thick, while interior doors are often thinner, and some high security deadbolts are built for the thicker size. Knowing the thickness early prevents ordering a bolt that won't reach or a cylinder that sticks out.
- Order spare keys with the cylinders. Reorders for patented systems go through authorized channels and need verification, so they take longer than a hardware-store copy. Two spares, one at home and one stored elsewhere, cover most households. Businesses should plan by role instead of by head count.

Frequently asked questions
What do I receive when the installation is finished?
You get numbered keys, a registration record or owner card where the system uses one, and a written summary of the hardware installed and the work done on the frame. We walk you through how reordering works and who may authorize copies. Store the card away from the keys, in a safe or deposit box.
Can you install a high security lock I bought online?
Often, yes, after a few checks. We confirm that the model fits your door, that it appears genuine and that extra keys can be ordered. If a seller can't supply keys or the product is a gray-market item, we tell you before drilling. Bring the box and any key card or paperwork to the survey.
Which brands do you install in Pomona?
We work with patented systems such as Medeco, Mul-T-Lock, ASSA and Schlage Primus, along with other listed high security cylinders, depending on your door and how a given line's keys are sourced. We recommend the product that fits your doors and your risk, and we tell you early if a line you want is one we can't supply.
Will the installation leave holes or damage on my door?
Not when it's done carefully. Retrofits reuse existing holes. Where new bores are needed, we use jigs and hole saws, protect the finish and clean up. On older or metal doors, we tell you what we can do without causing damage. If the door can't take the upgrade, we say so before cutting.
How much does high security lock installation cost?
It depends on the product line, how many cylinders and formats are involved, whether a retrofit works, what the frame needs and how many keys you want registered. We don't quote a final figure without seeing the doors. After the survey you receive an itemized written quote, and nothing is ordered or drilled until you approve it.
Can a high security lock go on a fire-rated door?
Yes, with limits. Fire-rated doors carry a label, and field drilling is restricted, so we install into the existing prep or use cylinder swaps that don't require new holes. Adding a deadbolt where none exists may not be permitted. We check the label first and explain what is allowed before we order anything.
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.
