What counts as a high security lock, and who needs one in Redondo Beach?
A standard keyed lock from a hardware store is built to a price and a convenience target. The pin tolerances are loose, the keyway is common, and the blank key can be cut at almost any kiosk. That is fine for a lot of doors. It is not fine for every door.
A high security lock is a cylinder, and sometimes the whole lock body, designed to resist the specific ways locks get beaten without a key: picking, bumping, drilling, and unauthorized key copying. It usually pairs tighter manufacturing with a restricted keyway, meaning the key blanks are controlled and a copy cannot be cut on a whim.
In Redondo Beach the people who ask us about this tend to fall into a few groups. Some own a home or townhome and want a front door they do not have to wonder about. Some manage a condo or rental where a dozen old keys are floating around. Some run a shop or restaurant and want keys that employees cannot quietly duplicate. Some keep a boat and gear near the harbor and are tired of replacing corroded hardware.
One honest note up front: a high security cylinder protects the lock. It does not fix a weak door, a loose strike plate or a thin frame. We look at the whole opening when we quote, and we will tell you if money is better spent on the door than on the cylinder.
How do pick-resistant and bump-resistant locks actually work?
Most pin-tumbler locks can be picked or bumped because the internal parts have small gaps that an attacker can exploit. High security cylinders close those gaps in several ways. Not every product uses every feature, which is why we explain what is inside before we recommend anything.
- Security pins: spool, serrated and mushroom-shaped pins give false feedback when someone picks the lock, so the tension and feel do not behave the way a picker expects.
- Tighter tolerances: parts are machined closely enough that the small movements bump keys and rakes depend on are much harder to produce.
- Complex or sidebar keyways: some designs add a second locking element that must be satisfied by cuts on the side of the key, not only the top edge.
- Drill and pull resistance: hardened inserts and shielded pins make drilling slower and more difficult, and better cylinder housings resist being pulled or snapped.
- Restricted key control: the key blank is patented or controlled, so a copy requires authorization rather than a trip to a general key machine.

Call (213) 577-1366Why do restricted keys matter for condos, rentals and shops?
People focus on picking, but in practice the most common way a lock fails is the key itself. A former tenant, a contractor, a roommate who moved out, a part-time employee: any of them may have had a copy made years ago. With a standard key you cannot know who holds one.
A restricted key system changes that. Copies are made only with proof of authorization, usually through the locksmith that set up the system and the person or entity named on the account. That does not make duplication impossible, but it moves it from casual to deliberate, and it gives you a paper trail.
For a multi-unit property or a business, restricted keys also combine well with a master key system, so staff or managers carry one key that opens what they need and nothing more. We set the hierarchy up with you on paper first, because it is much easier to design correctly than to untangle later.
If you only need new keys cut for a lock we already installed, our key duplication service explains how authorized copies work for restricted keyways.
How do we handle a high security lock installation, step by step?
Whether it is a front door in South Redondo or a back office door at a business, the process is the same. David oversees how we approach each job, and we do not guess at the door before we have seen it.
- You call (213) 577-1366. We ask what the door is, what it protects, how many keys you want in circulation, and whether this is a one-time upgrade or a response to something that happened.
- We inspect the opening: door material and thickness, the existing bore holes, the strike and frame, the condition of the hinges, and any corrosion on the hardware.
- We recommend a level of protection that fits the door. Sometimes that is a high security cylinder in your existing lockset. Sometimes it is a new deadbolt or a complete replacement because the old hardware cannot carry the upgrade.
- We explain the key control options, including how many keys come with the system, who can authorize copies, and what happens if you lose one.
- We install, adjust and test. The bolt should throw smoothly into the strike with no forcing, the key should turn cleanly, and the door should close without rubbing.
- We hand over the keys and any key-control paperwork, and we explain who to contact for copies later. If something feels stiff in a month, call us and we will look at it.

Call (213) 577-1366What affects the cost of high security lock installation?
We do not quote numbers on a web page because the range between two high security jobs can be wide, and a figure out of context is worse than useless. What we can do is tell you exactly what moves the cost, so the quote you receive makes sense.
Starting with the lock itself: a pick-resistant cylinder that drops into your existing hardware is usually the more economical route compared with replacing the whole lockset. A full replacement costs more but may be the right call if the old body is worn or poorly made.
- The cylinder or lockset you choose, and how much of its protection comes from patented key control versus tighter manufacturing alone.
- How many doors are involved and whether they should all share one key (keyed alike) or work in a hierarchy.
- The number of keys you want, and whether they are restricted blanks with controlled duplication.
- The condition of the door, frame and strike, since reinforcement or repair may be needed for the lock to do its job.
- Whether the work is scheduled or urgent, and whether a mobile van visit is needed after hours.
- Corrosion or damage to existing hardware that complicates removal.
What do high security locks look like on Redondo Beach doors?
Local housing shapes what we install more than any product catalog does. Here is how it plays out in the neighborhoods we get asked about, using what we know of the city.
South Redondo (ZIP 90277) mixes 1950s and 1960s single-family homes, beach homes in The Avenues, and condo buildings near the pier and Esplanade. Older single-family doors often have a worn standard deadbolt that has been rekeyed or passed between owners several times. A pick-resistant cylinder with a restricted key is a natural upgrade there, particularly when the home has changed hands or has a history of contractors with keys.
In Hollywood Riviera, Spanish and mid-century styles on hillside streets mean decorative entry doors and, often, heavier hardware. We pay attention to the look of the lockset because it matters as much as the cylinder, and we aim for a high security option that sits properly on the door instead of looking tacked on.
North Redondo (ZIP 90278) is known for dense two-on-a-lot townhome development, including the tall, narrow townhomes of Golden Hills. Those units often have a street-facing front door and a garage or side entry that the owner uses daily. Keying the entries alike on one restricted key cuts down the key ring and keeps control tight. If you are locked out of one of these townhomes first, our emergency locksmith service handles that, and the security upgrade can follow when things are calmer.
Brookside Village is a large gated condominium community, and condo rekeys and mailbox lock changes are common there. A resident who has moved in or had keys lost may want a restricted-key cylinder on the unit door and a mailbox lock replacement on the same visit. Because condo associations often have rules about exterior hardware, we advise you to check with your HOA or management before changing anything visible from outside.
Then there is salt air. Along the Esplanade, the pier and King Harbor, steady coastal exposure corrodes exterior hardware. High security cylinders are precise parts, and corrosion hurts precision. We steer toward corrosion-resistant finishes and materials for exterior-facing locks, and we recommend a cylinder that is shielded from direct weather where the door design allows. Inland North Redondo is slightly more sheltered but sits within the marine layer belt, so mornings stay damp much of the year and hardware still ages faster than you might expect.
At King Harbor, dock boxes, gates and marina hardware live in the harshest conditions in the city. A restricted-key padlock or cylinder is useful when several people share access to a dock but you want to control who can make copies. We choose materials built for the environment rather than a standard indoor-rated product.

Call (213) 577-1366Do businesses near Riviera Village and the pier need commercial security locks?
Commercial security locks are a related but distinct need. A boutique in Riviera Village has a storefront door, a back door and often a stock room, and each one may benefit from a different level of protection. A restaurant near the Redondo Beach Pier deals with staff turnover, late-night closings and back-of-house doors that get hard use.
For a business, the key question is control. Who has keys, who made copies and when did anyone last change the combination of access? A restricted-key cylinder answers part of that, and a documented key list answers the rest. We also look at whether the door hardware itself, such as a panic device or door closer, is in good shape, because a strong cylinder on a sagging door is still a weak door.
Our commercial locksmith page covers the broader range of business work. On this page the focus stays on the cylinders and key control that make a door harder to defeat quietly.
Why call Wilshire Lock & Key for high security locks?
We have been in business since 1987, and high security work rewards that kind of experience, because installation quality matters as much as the product. A good cylinder badly fitted is a frustrating lock.
We are one company, not a call-center dispatching your job to whoever is nearest. You reach our line at (213) 577-1366, answered every hour of every day, and the person who plans the work is the person accountable for it. We run a storefront at 10740 Wilshire Blvd in Westwood and mobile service vans, so we can come to your door or you can bring hardware in.
David, the owner and lead technician, oversees our approach to each job. If a request does not make sense for your door, we say so.
Regarding credentials: California requires locksmith companies to hold a Bureau of Security and Investigative Services (BSIS) locksmith company license, known as an LCO license. Ask any locksmith you consider, including us, for that license number before work begins. A legitimate company will give it to you without hesitation.
Redondo Beach is about 20 miles from our base, and we serve it as part of the 140 cities we cover across Los Angeles and Ventura counties. For a wider view of what we do in the city, visit our Redondo Beach locksmith page.
What should you do before you call about high security locks?
A few minutes of preparation makes the visit faster and the recommendation better. None of this is required, but it helps.
First, note how many doors you want to upgrade and whether they should open with the same key. Second, decide who should be allowed to authorize copies: just you, a property manager, a business partner. Third, check whether your building has HOA rules about exterior hardware, especially in condo communities. Fourth, take a photo of each door, including the edge where the latch sits and the frame around it.
If you are also considering electronic options, we can discuss how a smart lock installation compares. Smart locks offer convenience and access logs, while mechanical high security cylinders offer simple, durable key control. Some customers want both, and the two can coexist on different doors.
If your goal is simply to stop old keys from working, a lock rekey is sometimes enough. We will tell you honestly when a rekey solves the problem and a high security upgrade is not necessary.
Frequently asked questions
What is the difference between a high security lock and a regular deadbolt?
A regular deadbolt relies on a bolt and a standard pin-tumbler cylinder with loose tolerances and a common key. A high security lock improves the cylinder with security pins, tighter machining, and often a restricted keyway with controlled key duplication. The bolt matters too, so we often look at both parts. Pairing a good cylinder with a solid deadbolt installation gives the strongest result for most doors.
Can a pick-resistant lock still be picked?
Resistant does not mean impossible. A skilled person with enough time and the right tools can defeat many locks. What high security cylinders do is raise the skill, time and noise involved, and make casual methods like bumping and basic raking far less likely to work. We will not tell you a lock is unbeatable, because no honest locksmith can.
Do bump-resistant locks work against bump keys?
Bump-resistant designs use features such as security pins, tighter tolerances and sidebars to disrupt the way a bump key works. They are meant to make bumping unreliable or ineffective. How well a particular cylinder resists depends on its construction, which is why we explain what is inside the lock instead of just naming a category.
Can you upgrade the cylinder in my existing lock, or do I need a whole new lockset?
Often the cylinder can be swapped into your existing hardware, which is usually the more economical route. If the lock body is worn, poorly made or incompatible with the cylinder you want, a full replacement makes more sense. We check the lock in person and tell you which one applies before doing the work.
Will high security locks hold up against salt air near the coast?
Coastal exposure along the Esplanade, pier and King Harbor does corrode exterior hardware, and precision cylinders are more sensitive to that than loose ones. We recommend corrosion-resistant materials and finishes for exposed doors and gates, and shielding where possible. No lock lasts forever in salt air, but the right choice and some occasional maintenance extends its life.
Can I get copies of a restricted key at a hardware store?
Typically no, and that is the point. Restricted key blanks are controlled, and copies are made through authorized channels with proof that you are allowed to request them. If you lose a key or need more, call us at (213) 577-1366 and we will explain what the process requires for your particular system.
I manage a condo or rental in Redondo Beach. Are high security locks worth it?
They can be, especially when tenants turn over often and old keys remain in circulation. Restricted keys limit unauthorized copying, and a master key hierarchy keeps access organized. For some properties a straightforward rekey between tenants is enough, and we will tell you when that is the case. Check HOA rules before changing any exterior hardware.
Do you install high security locks outside regular business hours?
Our phone is answered 24 hours a day, 7 days a week, year-round at (213) 577-1366, and our mobile vans can come to you. If a lockout or break-in is involved, we handle the emergency first, then plan the upgrade. For planned work, we are happy to schedule a visit that suits you.
How do I know a locksmith in Redondo Beach is legitimate?
Ask for their BSIS locksmith company (LCO) license number, which California requires. Ask who will actually come to your door and whether the company has a real address. We are at 10740 Wilshire Blvd in Westwood and have operated since 1987. Be cautious of anyone who refuses to explain the work before starting.
