What actually makes a lock high security?
A standard pin-tumbler lock from a hardware store is built to a price and a convenience. It works, but it can be picked or bumped by someone with the right tools and a little practice, and the keys can be copied at almost any kiosk. A high security lock is built differently, and the differences are specific rather than a matter of marketing.
When we talk about high security locks, we mean a cylinder and key system with some combination of the following features. Not every product has all of them, and part of our job is telling you which ones matter for your door.
- Pick resistance: tighter machining tolerances, security pins (spool and serrated shapes), and extra locking elements that make manipulating the cylinder much harder.
- Bump resistance: internal designs that don't let a single bump key set all the pins at once. No lock is magically immune, but a well-built cylinder makes bumping impractical.
- Drill and tamper resistance: hardened inserts in the places a drill or pry tool usually goes first.
- Restricted keys: key blanks protected by patent or controlled distribution, so a stranger can't walk into a shop and get a copy cut.
- Key control: records of who holds which key, and a process for authorizing additional copies.
Why Valencia homes and businesses ask for upgraded locks
Most of the people who call us about high security locks are not in a panic. They have a front door that has had the same builder-grade cylinder since the house went up, and something has made them look at it again: a neighbor's break-in, a contractor who had a key, a tenant who moved out without returning copies, or simply a new house they want to feel sure about.
Valencia is a good example of why the key question matters as much as the lock. It is a master-planned community of HOA-governed single-family tracts built from the 1960s through the 2000s, plus townhome and condo clusters near Town Center. In a tract that old, a house may have changed hands several times, and every owner, renter, painter, and relative may have been handed a key. The cylinder might be perfectly sound and still be a poor protector, because nobody can say how many copies exist.
That's the situation a restricted-key system fixes. A pick-resistant cylinder keeps out the person who tries to defeat the lock, and a restricted key keeps out the person who tries to copy their way in. Sometimes you need both, sometimes only one, and sometimes the better money goes somewhere else on the door entirely. We'll tell you which.

Call (213) 577-1366How we install or replace a high security lock, step by step
Whether you call us for a single front door or a row of commercial doors, the process is the same. It's a short conversation and a careful look, not a sales pitch.
- You call (213) 577-1366. We answer around the clock, so there's no waiting for a business-hours callback. Tell us the type of door, what the lock is now, and what's driving the change.
- We look at what you have. That means the existing cylinder, the deadbolt or handleset, the strike plate, the door edge, and the frame. We check whether the door can actually support the upgrade.
- We explain your realistic options. You may be choosing between a high security cylinder in your existing hardware, a new deadbolt built around a high security cylinder, or a full hardware replacement. We'll lay out the tradeoffs in plain language.
- We talk about keys. Restricted keys come with rules about who can authorize copies, and some systems take longer to order than a standard blank. We settle how many keys you need and who will hold them before we order anything.
- We install and fit the hardware. Alignment gets real attention: a precision cylinder in a sticking door will frustrate you every day, so we adjust the strike and the latch until the bolt throws freely.
- We test it with you. You operate the lock with each key, from inside and outside, with the door open and closed. We hand over the keys and any key-control paperwork, and we explain how to order copies later.
What a better cylinder can't fix: the door, frame, and strike
Here's something many sellers skip. The most pick-resistant cylinder in the world is only as strong as the door it's mounted in. Most real-world forced entries don't involve picking at all. Someone kicks the door, the strike plate tears out of a thin frame, and the lock never has to fail.
So when we put a high security lock on a Valencia house, we look at the whole assembly. A deadbolt with a short strike screw sitting in soft wood is a weak point no matter what's inside the cylinder. Long screws into the framing, a reinforced strike, and a solid door core all matter. If your door is hollow or damaged, we'll say so and discuss it, even though it means your upgrade is a bit larger than you expected.
We'd rather tell you that a standard-grade deadbolt plus a properly reinforced frame is the right call than sell you an expensive cylinder to put on a door that won't hold. And if you want more on the hardware side, our deadbolt installation page covers the strike and frame details in depth.

Call (213) 577-1366How much do high security locks cost in Valencia?
We don't quote numbers on a web page, because honest pricing for this work depends on things we can only see at your door. What we can do is show you exactly what moves the cost, so you know what you're paying for.
The factors that matter most:
- Which lock system you choose. Restricted-keyway systems with patent protection cost more to produce than a standard cylinder with security pins. A lock rated to a higher grade costs more than a basic one.
- How many cylinders. Keying several doors alike on one restricted key is common and convenient, but it changes the ordering and the number of cylinders involved.
- How many keys you need, and who may authorize more. Restricted blanks are more expensive to cut and sometimes require paperwork.
- Whether we're upgrading cylinders in hardware you already own or replacing the whole lock. Reusing good existing hardware is usually the more economical route, as long as it's in good shape.
- Door and frame condition. Reinforcement, strike upgrades, or door repairs add to the job, but they also add to the real security.
- Lead time on parts. Some systems are in stock and some are ordered, and an emergency or after-hours visit differs from a scheduled one.
- Travel. Valencia is about 34 miles from our Westwood storefront, and we take that into account when we schedule the visit.
Valencia specifics: villages, paseos, dust, and HOAs
Valencia's layout shapes how we approach high security work. The community is organized into named villages linked by the paseo walkway system, and most of those villages sit under HOA governance. Before you change exterior hardware in Valencia Glen, Northpark, Bridgeport, or Old Orchard, it's worth reading your HOA rules on exterior door hardware and finish. Some associations care about the look of the front door, and we can usually match finish and style while changing what's inside the cylinder. A high security cylinder often looks the same from the outside as an ordinary one, which makes it easy to upgrade without a fuss.
Gated enclaves, such as those in Westridge and the north edge of Tesoro del Valle, add another consideration. A gate at the entrance doesn't replace a good lock on the door, and it adds another set of keys, codes, or remotes that may be in circulation. We treat the front door as its own line of defense, and if you're also dealing with a gate, our team can sort that out separately.
Climate matters here more than people expect. The Santa Clarita Valley has hot, dry summers with large day-to-night temperature swings, and that causes seasonal door and frame movement. Wood and metal expand and contract, and a bolt that slid freely in April can bind in August. Precision cylinders tolerate this fine, but a misaligned strike makes the lock feel stiff and wears the parts faster, so we set alignment with the seasons in mind. Santa Ana wind events also push fine dust into exterior locks. A quality cylinder resists that better than a loose, worn one, and we'll tell you how to care for it so it keeps turning smoothly.
Some local scenarios where the high security conversation comes up naturally:
- Mailbox and cluster-box locks in paseo-linked village HOAs. These are shared, exposed, and often forgotten for decades. If your association is thinking about a change, see our mailbox lock replacement service.
- New construction in FivePoint Valencia, where buyers often want controlled keys from day one and sometimes pair a restricted cylinder with electronic hardware. See smart lock installation if you're weighing that route.
- Condos and apartments near Town Center and along the McBean Parkway corridor, where tenant turnover is the real risk and key control is the practical fix.
- Homes in the 91354 and 91355 ZIP codes that have changed hands a few times and still run on the original builder cylinders.

Call (213) 577-1366Commercial security locks and key control in the Valencia Industrial Center
Businesses have a different problem from homeowners. A shop or warehouse may have a dozen employees, a few vendors, and a history of people coming and going. The question isn't only how hard the lock is to pick, but who holds the keys and how you get them back.
In the Valencia Industrial Center, we see the same pattern over and over: one key that opens everything, copied years ago by someone who no longer works there. A restricted keyway plus a master-key structure changes that. Employees get keys that open only their areas, you hold a master, and nobody can walk into a key shop and duplicate a restricted blank. If that's the shape of your problem, our master key system page covers the design, and our commercial locksmith service covers the doors themselves.
For commercial security locks we also look at the door type. A glass storefront door, a steel rear door, and an interior office each call for different hardware, and we'll match the lock to the door rather than the other way around.
Why call Wilshire Lock & Key
We've been in business since 1987, and we serve 140 cities across Los Angeles and Ventura counties, Valencia among them. We have a real storefront at 10740 Wilshire Blvd in Westwood plus mobile service vans, so you're dealing with one company rather than a call center that sells your job to whoever is nearest. Nobody is dispatching you to a subcontractor we've never met.
David, the owner and lead technician, oversees the work. For a high security installation that matters, because the decisions are judgment calls: which system fits, whether the door is ready, how many keys to authorize. We'd rather make those calls with you at the door than hand you a catalog.
One more thing worth knowing: California requires locksmith companies to hold a BSIS LCO license, and you should ask any locksmith for it before they start work. That includes us. It's a reasonable thing to ask, and a company that dodges the question is telling you something.
If your problem is more urgent than an upgrade, such as a lockout tonight, our emergency locksmith page is the better starting point. The phone number is the same: (213) 577-1366.
What to have ready when you call
A few details make the first conversation faster and more accurate. You don't need all of them, and we'll help you figure out the rest.
- The type of door (wood, steel, glass, or fiberglass) and whether it's an entry, side, garage, or interior door.
- What lock is on it now, if you know, and roughly how old the house or building is.
- How many keys exist and whether any are missing or held by people you'd rather not have them.
- Whether you're in an HOA village or gated enclave, and whether you've checked the exterior hardware rules.
- Whether you need copies right away. For ordinary keys, see key duplication, but understand that restricted keys follow different rules.
Frequently asked questions
Are high security locks really pick-proof?
No lock is pick-proof, and anyone who says otherwise is overselling. High security locks are pick-resistant and bump-resistant, which means they take far more skill, time, and specialized tools to defeat. For most break-ins, that's enough to make the attempt impractical. The door, frame, and strike still matter just as much.
What is a restricted key, and why does it matter?
A restricted key is cut on a blank that's protected by patent or controlled distribution, so you can't have it copied at an ordinary kiosk or hardware store. Copies typically require authorization, such as a key card or ID. It matters because it solves the problem of unknown copies floating around, which is common in older homes and rental units.
Can you upgrade just the cylinder, or do I need a whole new lock?
Often we can swap the cylinder and keep your existing hardware, provided the hardware is sound and compatible. That's usually the more economical route. If the deadbolt itself is worn, low-grade, or doesn't fit the door, we'll recommend replacing it. We decide after we see the door.
Will a high security lock look different from my current one in my HOA village?
Often it looks nearly identical from the outside, since much of the difference is inside the cylinder and in the key. We can usually match the finish and style to what's already on the door. Still, check your HOA's exterior hardware rules first, especially if you're replacing a visible deadbolt or handleset.
How is this different from rekeying my locks?
Rekeying changes the pins inside your existing cylinder so old keys stop working. It's useful, and it's often the lighter-cost fix after a move or a lost key. A high security lock replaces the cylinder with one that resists picking and bumping and may use a restricted key. See our lock rekey page if rekeying fits your situation better.
Do high security locks work in Valencia's heat and dust?
Yes, though they benefit from care. Summer heat and big day-night swings move doors and frames, so we set the strike and latch alignment with that in mind. Santa Ana winds carry dust into exterior cylinders, and we'll show you how to keep them clean. A properly aligned precision lock should turn smoothly year-round.
Can you do high security locks for my business, not just my house?
Yes. Commercial security locks are a regular part of our work, including restricted keyways and master-key structures for shops and industrial units. The choice depends on your doors, your staff, and how you control key distribution. We'll walk through that with you at the site.
Can I get a high security lock installed outside business hours?
Yes. We answer the phone 24 hours a day, seven days a week, year-round, at (213) 577-1366. Urgent situations come first, but if you simply want an upgrade done at an odd hour, call and we'll talk through what's possible.
