What counts as a high security lock, and what doesn't?
A high security lock is not simply a lock with a heavy feel or a shiny finish. It is a lock built to resist the specific ways burglars get through ordinary ones: picking, bumping, drilling, forced turning and unauthorized key copying. The hardware at the big-box store and the lock that came with your 1990s remodel are usually built to a price, with loose tolerances and common keyways that anyone can buy blanks for.
A real high security cylinder tightens all of that up. It typically uses tighter-tolerance pins or a secondary locking element such as a sidebar, anti-drill hardened inserts, and a restricted keyway. A restricted keyway means the key blanks are controlled by the manufacturer, so a copy generally can't be cut at a random kiosk. You usually need proof of authorization, or the original key card, to duplicate it.
We install pick-resistant locks, bump-resistant locks, and restricted-key systems for both home security locks and commercial security locks. We'll also tell you plainly when a higher grade of lock won't help, because a good cylinder on a weak door or loose strike plate is money spent in the wrong place.
Why do Hermosa Beach homes and businesses ask for high security locks?
Hermosa Beach is under 1.5 square miles and densely built. Small-lot cottages from the 1920s onward sit next to rebuilt multi-story townhomes, and duplexes, triplexes and small apartment buildings are common in the Sand Section and along the Pacific Coast Highway and Aviation Boulevard corridors. Walk-street and alley-access homes near the beach put entry doors close to foot traffic. A high share of renters and frequent unit turnover means a lot of keys have passed through a lot of hands.
That last point is the most common reason people call us about this service. Nobody can say for certain how many copies of a standard key are floating around a building that has changed tenants several times. A restricted-key cylinder gives an owner or resident a way to control who can duplicate a key, and it adds real resistance to picking and bumping on the door that matters most.
Other callers are business owners around Pier Plaza and Downtown who want better hardware on back doors, storerooms and offices. Others live in a beachfront unit where the salt air has chewed up the old lockset and they would rather replace it once with something built to last. Each of those is a different job, and we scope them differently.

Call (213) 577-1366How we handle a high security lock installation, step by step
Whether you call at midday or in the middle of the night, the process is the same. David runs this company the way he has since 1987, and that means looking at the door before talking about products.
- You call (213) 577-1366. We answer around the clock and ask what door you're protecting, what lock is on it now, and what prompted the call: a break-in, a tenant change, lost keys, or a general upgrade.
- We look at the whole entry, not just the cylinder. That means the door material and thickness, the frame, the strike plate, the screws, the hinges, and any glass within reach of the lock.
- We recommend a specific cylinder and lockset, explain what it resists and what it doesn't, and tell you how many keys come with it and how extra keys are authorized.
- If the door or strike needs reinforcement to make the new lock worth installing, we say so, and you decide what to do. We won't add work you don't need.
- We install the hardware, check that the bolt throws fully and the door closes without binding, and test every key.
- We go over key control with you: where the key card or authorization paperwork goes, who is allowed to order copies, and what to do if a key is lost.
Pick-resistant versus bump-resistant: what are you actually buying?
These two terms get used as if they mean the same thing, but they describe different weaknesses. Picking is manipulating the pins one by one with tools. Bumping uses a specially cut key and a sharp tap to jump the pins momentarily and turn the cylinder. A standard pin-tumbler lock is vulnerable to both. A well-built high security cylinder addresses both, usually with modified pin shapes, extra security pins, or a second locking mechanism that a bump key can't defeat.
One honest note: no lock is pick-proof. Pick-resistant means it takes much more skill, time and specialized tools, which is exactly what deters most break-ins. Burglars tend to prefer the easy way in, and the easy way is often a kicked door, a pried frame or a broken window beside the lock. That's why we look at the door assembly as part of every job.
What you get from a good bump-resistant, pick-resistant cylinder:
- Tighter manufacturing tolerances that make rake and bump attacks far less effective.
- Hardened inserts that protect against drilling at the shear line.
- A restricted keyway, so key blanks are not sold over the counter.
- Key control paperwork or a key card that governs who can order duplicates.
- Corrosion-resistant finishes available for the coast, which matters in Hermosa Beach.

Call (213) 577-1366What affects the cost of high security lock installation in Hermosa Beach?
We don't quote numbers on a web page, because the honest answer depends on your door. What we can do is tell you what moves the price so you aren't surprised when we give you a figure over the phone or on site.
- The grade and type of lock. A high security cylinder alone costs less than a full high security deadbolt or a complete lockset with a reinforced strike.
- How many locks you need. Having several doors keyed alike, so one key opens the front, back and garage entry, changes the total and the work involved.
- The key system. Restricted keys cost more than common ones, and extra authorized copies add to the total.
- The condition of the door and frame. A split frame, a worn strike or a swollen door may need repair before the new lock can do its job.
- Finish and corrosion resistance. Beachfront units often warrant a finish chosen for salt air.
- Whether it's a planned appointment or an after-hours emergency call. Night and weekend service is available, and timing can affect the price.
- Retrofitting versus replacing. Sometimes only the cylinder in your existing lock body needs to change. Sometimes the whole lock does. The lighter-cost option is usually the cylinder swap, when the existing hardware is sound.
Why call Wilshire Lock & Key for a high security locksmith?
Plenty of companies list a number and send whoever is closest. We run differently, and these are the reasons that matter for a job like this one.
- We've been in business since 1987. High security hardware is one area where experience shows, because choosing the right lock for the door matters more than installing the most expensive one.
- We have a real storefront at 10740 Wilshire Blvd in Westwood, plus mobile service vans. You're dealing with a company with an address, not a call center that resells your job.
- It's one company. No dispatch middleman hands your job to a stranger and takes a cut. The people who answer the phone are the ones accountable for the work.
- David, the owner and lead technician, oversees the work. If a recommendation seems like too much or too little, you can ask him why.
- We serve 140 cities across Los Angeles and Ventura counties, and Hermosa Beach is about 19 miles from our Westwood base.
High security locks across Hermosa Beach: Sand Section, Hermosa Valley and the corridors
Different parts of the city lead to different conversations. In the Sand Section, where duplexes and triplexes are common, the pattern we hear about is rental turnover. An owner wants one restricted-key system so that a former tenant's copy doesn't still open the door. In that situation, a high security cylinder is often the most useful upgrade. If you only need the existing locks recombined to new keys, lock rekeying may be the more economical route, and we'll tell you honestly which one fits your building.
In Hermosa Valley and the older wood-frame cottages, the issue is often door condition. Marine layer damp can swell old wood doors and make deadbolts stick. A premium cylinder in a door that binds only transfers the problem. We check the fit first, and where it makes sense, we pair the new cylinder with a proper deadbolt installation so the bolt lands cleanly in a solid strike.
North Hermosa, South Hermosa and East Hermosa have their share of rebuilt multi-story townhomes and older cottages on small lots. Walk-street and alley-access entries near the beach are the ones we tend to look at most closely. A door that opens onto a path with regular foot traffic deserves a cylinder that resists tampering, and it deserves a frame that can take a hit.
Along the Pacific Coast Highway and Aviation Boulevard corridors, where small apartment buildings and mixed-use properties sit, the question is usually one of key hierarchy. Owners want unit doors, shared entries and utility rooms keyed in a way that makes sense. For those cases we can build a controlled system, see master key systems, on restricted keyways.
Everything in the city falls under ZIP code 90254, and we work across it, from beachfront units to the blocks east of the highway. One scenario comes up again and again for us in this part of town: replacing corroded exterior locksets on beachfront units. If a lock is already seized or green with salt, the conversation about upgrading is easy, because you're replacing it anyway. A high security lock chosen with a corrosion-resistant finish is a sensible choice there.

Call (213) 577-1366Salt air, damp and the toll on high security hardware
The entire city sits within a few blocks of the ocean, so salt-air corrosion of exterior locks, hinges and gate hardware is routine here. It affects high security locks too. The internal parts of a quality cylinder are built to a higher standard, but the outside of the lock, the screws and the strike plate still face the air every day.
What we do about it is practical. We choose finishes suited to exposed coastal doors, use fasteners that won't rust into the frame, and pay attention to the parts that wear first. Hinges and strike plates on older doors are often more worn than the lock. If your gate or side door, for example along the Hermosa Valley Greenbelt, has hardware that has corroded, we may suggest lock repair or replacement as part of the work, or we may point you toward a different gate hardware solution altogether.
One tip we give to every beachfront customer: if a key starts to feel gritty or the lock turns stiffly, don't just spray it with household oil. Call us. The wrong lubricant can gum up the pins and make the problem worse, and a cylinder that's binding is telling you something.
Commercial security locks and key control for Pier Plaza businesses
Bars, restaurants and shops around Pier Plaza and Downtown have a different set of risks from homes. Many people have keys, staff change often, and the back door faces an alley after closing. For a business, the value of a high security lock is largely about key control: knowing that a former employee cannot walk into a hardware store and order a copy.
We can fit restricted-key cylinders on back doors, storerooms, offices and cash-handling areas, and set them up so that only the owner or a designated manager can authorize duplicates. For doors that also need exit hardware, such as the rear exits at busy venues, a high security cylinder can work together with panic bar installation so the door stays secure from outside and code-compliant from inside. Our broader commercial locksmith work covers the rest of the doors and hardware on the property.
A word about what we don't do on this page: we aren't recommending a lock because it sounds impressive. For a storefront with a glass door, a better cylinder helps, but the glass and the frame matter just as much, and we'll say so.
What to know before you buy: honest limits and good questions
A few things worth knowing before you spend money on high security hardware, wherever you buy it.
First, ask any locksmith for their California locksmith company license. The state requires locksmith companies to hold a license through the Bureau of Security and Investigative Services, known as a BSIS LCO license. You're entitled to ask for it, and a legitimate company will answer plainly. Ask us the same question.
Second, key control is only as good as how you handle it. A restricted key still opens the door if it's left under a mat. Keep the authorization card somewhere safe, and tell us if it's lost, because that affects how copies are ordered.
Third, think about the whole door. A good cylinder is the heart of the system, but the strike plate, the frame, the hinges and nearby glass decide whether the lock gets tested. If you're also considering electronic options, our smart lock installation page covers that, and many customers pair a smart lock on one door with a high security mechanical cylinder on another.
Finally, if you've just had a break-in or lost keys and need the door secured tonight, call us for emergency locksmith service first. We can make the door safe now and schedule the proper high security upgrade when you're ready.
Frequently asked questions
What is the difference between a high security lock and a regular deadbolt?
A regular deadbolt is built to a standard price and usually has a common keyway that anyone can buy blanks for. A high security lock uses tighter tolerances, extra pin or sidebar protection, hardened anti-drill parts and a restricted keyway. That makes picking, bumping and unauthorized copying much harder. It still needs a solid door and frame to do its job.
Can a high security lock be picked or bumped?
No lock is completely pick-proof, and we won't tell you otherwise. A quality pick-resistant, bump-resistant cylinder takes far more skill, time and specialized tools to defeat, which is why it deters most attacks. Many break-ins, though, come through the door, frame or a nearby window, so we assess those too.
Do you install high security locks in Hermosa Beach at night or on weekends?
Yes. We answer the phone 24 hours a day, 7 days a week, year-round, at (213) 577-1366. If you need a door secured right away, we can handle that first and plan the full high security upgrade for a time that suits you.
How much does high security lock installation cost?
It depends on the lock grade, how many doors you're doing, the key system, the condition of your door and frame, the finish, and whether the call is after hours. Over the phone we'll ask a few questions and explain the price factors. A cylinder swap in sound hardware is usually the more economical route compared with replacing the whole lockset.
Can you upgrade just the cylinder, or do I need a whole new lock?
Often only the cylinder needs to change, provided the existing lock body is in good shape and fits a high security cylinder. If the lock is corroded, worn or low-grade, replacing the whole lockset makes more sense. We'll check on site and tell you which applies.
Are high security keys hard to copy?
Restricted keys are meant to be. The manufacturer controls the blanks, and duplicates normally require authorization, such as a key card or the owner's approval on file. That's the point for rental properties and businesses: you decide who can have a copy. It does mean extra keys take a bit more effort to order than a standard one.
I own a duplex in the Sand Section with frequent tenant turnover. Is a high security lock worth it?
For many owners, yes, particularly on entry doors where key copies tend to multiply. Rekeying resets who has access, while a restricted-key cylinder also controls who can make copies afterward. Our page on locksmith services for landlords explains how we handle turnover work, and we can recommend the right balance for your building.
Will salt air damage a high security lock?
The internal parts of a quality cylinder are built to a higher standard, but exterior finishes, screws and strike plates still face the coastal air. We choose corrosion-resistant finishes and fasteners for beachfront doors. If your current lock is already seized or corroded, that's a good time to upgrade.
How do I know a locksmith is legitimate?
Ask for their California locksmith company license. The state requires locksmith companies to hold a BSIS LCO license, and you can ask any company to show it. Also look for a real address. Ours is 10740 Wilshire Blvd in Westwood, and we've been in business since 1987.
