What counts as a high security lock?
The phrase gets used loosely, so here is what we mean by it. A high security lock is a cylinder, and usually the whole lock body around it, built to resist the ways ordinary locks are defeated: picking, bumping, drilling, and unauthorized key copying. The lock on most homes and rental units is a basic pin-tumbler that a trained person, or a person with a cheap bump key, can open in seconds without leaving a mark.
A true high security cylinder changes that in a few specific ways. It uses tighter tolerances and security pins that fight a pick. It often adds a second locking element, such as a sidebar or a moving element in the key, so that lifting the pins alone does nothing. It usually has hardened inserts to slow drilling. And it comes with a restricted keyway, meaning the key blanks are controlled and a copy generally requires authorization from whoever owns the key card or registration.
No lock is pick-proof or bump-proof, and we won't tell you one is. What a good pick-resistant, bump-resistant cylinder does is raise the time, skill, and noise required to get past it, which is what actually discourages a burglar. That is the honest standard we hold every installation to.
- Pick-resistant: security pins and tight tolerances make manipulation slow and difficult.
- Bump-resistant: extra mechanisms keep a bump key from transferring force the way it does in a standard cylinder.
- Drill-resistant: hardened components protect the shear line from a drill bit.
- Restricted keys: controlled blanks mean copies are not available at a hardware-store kiosk.
Why are people in Lake View Terrace asking for high security locks?
Most of the calls we get about this come from a few situations. Someone has lost a key that was copied freely over the years and no longer knows how many duplicates are floating around. Someone has had a break-in or an attempted one on a rural-feeling lot where the nearest neighbor is a driveway away. Or someone is simply tired of a builder-grade lock that the previous owner, a former tenant, and three contractors all had keys to.
On a standard lock, key control is the quiet weak point. Anyone holding a key can walk into a shop and have a copy cut in a minute. A restricted-key system closes that gap. You decide who gets keys, and you can trace where they went. For a ranch house with a long driveway, a barn full of tack and equipment, or a small rental property, that control is often worth more than the lock's picking resistance alone.
The other reason is simply fit for the property. Lake View Terrace has a lot of exposed, larger parcels where a person can work on a door or gate without being seen from the street. When nobody is watching, the lock has to do more of the work by itself.

Call (213) 577-1366How we handle a high security lock installation, step by step
We keep the process plain and the decisions yours. Whether you call about a single front door or an entire property, this is how it normally goes.
- Call (213) 577-1366. Someone answers at any hour. Tell us what you want protected, what your door or gate looks like now, and whether it is a house, an apartment, a barn, or a business.
- We figure out the right scope. Sometimes a high security cylinder in your existing hardware is enough. Sometimes the deadbolt, strike plate, or door itself is the real problem and swapping only the cylinder would be wasted effort.
- We look at the door in person. We check the door's thickness and material, the bore holes, the frame, the strike and its screws, and the condition of the wood or metal. A strong cylinder in a loose frame is a weak lock.
- We explain your options and the trade-offs plainly: restricted keyway systems, grades of hardware, how key copying will work afterward, and what each choice does to the cost.
- We install the new hardware, align it, and test it with the door open and closed so it throws smoothly and the bolt seats fully into the frame.
- We hand you the keys and walk you through how to order more. With a restricted system, that means telling you who can authorize additional keys so you aren't surprised later.
- Before we leave, we make sure any old keys that matter no longer work. If you want the new cylinder keyed to match other locks you already own, we can plan for that too.
What affects the cost of high security lock replacement?
We don't quote numbers on a web page because the honest answer depends on the property, and a number without context just misleads you. What we can do is tell you exactly what moves the cost up or down, so that when we do quote you, it makes sense.
One thing worth saying clearly: a higher level of security does cost more than a basic lock, and the lighter-cost option is usually just a standard cylinder. But replacing one failing lock is often the more economical route compared with replacing every lock on the property, and sometimes rekeying is the right answer rather than new hardware at all.
- The security level of the cylinder: a pick-resistant and bump-resistant cylinder differs from one with a patented restricted key and drill protection.
- How many locks are involved: one front door is different from a house, a barn, a gate, and a detached garage all keyed alike.
- The state of the door and frame: if the strike, jamb, or door itself needs reinforcement, that is additional work worth doing.
- Whether the locks need to be keyed alike or on a master key system, which adds planning.
- Key quantity and the cost of restricted blanks, which are controlled and are not cut like ordinary keys.
- Outdoor exposure: weather-rated hardware for gates, padlocks, and barn doors is built differently from interior-grade locks.
- When and where we are called: after-hours trips and distant properties take more of our time than a scheduled visit.

Call (213) 577-1366Which high security lock fits your property?
The right answer for a ranch house is not the right answer for a Foothill Boulevard apartment or a barn gate. Here is how we usually think through it, and where we send you to a related service rather than overselling a lock.
For home security locks, the front and back doors are the priority. We typically pair a high security cylinder with a solid deadbolt and a reinforced strike. If you only need a stronger deadbolt on a door that has none, our deadbolt installation service covers that. If your existing locks are fine but you don't know who has keys, lock rekeying is usually the more economical fix and we'll tell you that honestly.
For replacing worn or compromised locks entirely, lock replacement is the broader service, and a high security cylinder is one upgrade within it.
For commercial security locks, a shop or office usually needs key control more than anyone, since employees come and go. Restricted keyways make that practical. If you are weighing a whole building rather than a single door, our commercial locksmith page covers the wider picture.
If you are drawn to keyless entry, say so. A smart lock can be a good fit for some doors, and our smart lock installation service is the place to start. It is a different category from a mechanical high security cylinder, and some people use both on the same property: a restricted-key cylinder as the backup and a smart lock for daily use.
What does high security hardware look like in Lake View Terrace?
This is a semi-rural neighborhood of 1950s through 1970s ranch homes, and many sit on horse-zoned lots with barns, corrals, and long gated driveways. That layout shapes what high security work looks like here more than any generic checklist would. Along the Wentworth Street equestrian corridor, a property often has several things to protect at different distances from the house: the gate at the road, the barn, a tack room, and the main residence. A single high security cylinder on the front door protects only one of them.
In the Hansen Dam area and up toward Little Tujunga Canyon, the lots tend to be larger and more exposed, and canyon-edge parcels especially so. Owners rekeying ranch homes near Little Tujunga Canyon often tell us the same thing: they bought the house, they don't know who has keys, and they want the next set controlled. That is a natural reason to move to a restricted keyway, so that new copies stop being something anyone can do at a counter.
Foothill Boulevard is different. Apartment and condo complexes cluster along it, and the question there is usually about who has authority to change locks. If you rent, check with your landlord before changing anything, since the building may already be on a keyed system. If you manage the property, a restricted key system helps you control tenant turnover, and our page for locksmith services for landlords is the better place to read about that kind of work.
The climate matters too. Foothill heat and strong seasonal Santa Ana winds push dust and grit through the Hansen Dam basin, and that can foul exterior gate locks and padlocks. Any exposed lock suffers from this, and tighter-tolerance cylinders do not like grit in the keyway. For outdoor locks, we choose weather-resistant hardware with covers where appropriate, and we advise against heavy oil sprays that turn dust into paste. If a gate lock is already sticking, our gate lock repair service is the starting point, and a high security upgrade can follow once it is working cleanly.
Summer sun also dries out wood doors on unshaded lots. A wood door that has shrunk or warped can leave the bolt barely catching the strike, and that undermines even an excellent cylinder. We check the door itself when we install, and we will tell you if the door needs attention before the lock does.
We work across ZIP code 91342, and we do it as a mobile service from our Westwood base, about 21 miles away, so we bring the tools and a range of hardware to your property rather than asking you to drive to us. If you would rather see options in person, the storefront at 10740 Wilshire Blvd is open to you.

Call (213) 577-1366Why call Wilshire Lock & Key for high security locks?
High security work is a place where it pays to deal with someone who has seen a lot of locks fail. Here is what we can honestly say about how we operate.
We have been in business since 1987. That is a long time to see which hardware holds up in Southern California heat and dust and which gets returned. We have a storefront at 10740 Wilshire Blvd in Westwood and mobile service vans, so there is a real place behind the phone number and a real vehicle that comes to you. We serve 140 cities across Los Angeles and Ventura counties.
You are dealing with one company, not a dispatch middleman who passes your call to whoever is nearest. David, the owner and lead technician, oversees the work, which matters most on jobs like this where the details of the door, frame, and key control decide whether the lock is worth having.
We answer the phone around the clock, every day of the year, at (213) 577-1366. If something has just happened and you need a lock changed tonight, our mobile locksmith service is built for exactly that. You can also reach us through our contact page when it is not urgent.
What should you ask any high security locksmith?
Whoever you hire, ask these questions. A reputable locksmith will answer them directly and won't be bothered that you asked.
California requires locksmith companies to hold a license from the Bureau of Security and Investigative Services, called an LCO license. Ask any locksmith, including us, for the license number and look it up with the state before work begins. It is a reasonable request and it protects you.
Beyond that, here are the questions that tell you whether you are getting real high security hardware or just a lock with a marketing label.
- Is the cylinder actually independently rated for pick, bump, and drill resistance, or is that just what the packaging says?
- Is the keyway restricted, and who can authorize additional keys?
- What happens to the old keys, and how do I know they no longer work?
- Do you check the door, frame, and strike, or only swap the cylinder?
- Will I get a clear quote after you see the door, rather than a number over the phone that changes later?
- Can you cut spare keys when I need them, and what will that process look like? Our key duplication page explains how it works for standard keys, and restricted keys follow the authorization rules described above.
Frequently asked questions
Are high security locks really pick-proof?
No lock is pick-proof, and anyone who says otherwise is selling something. A good high security cylinder is pick-resistant and bump-resistant, meaning it takes much more time, skill, and noise to defeat than a standard lock. That added difficulty is what discourages most break-ins.
Can you upgrade my existing locks to high security in Lake View Terrace?
In most cases yes. We look at your door, bore, frame, and strike first. Often we can replace the cylinder or the whole lock body and reinforce the strike without replacing the door. If the door is in poor shape, we will say so before we start.
Can someone copy a high security key at a hardware store?
Generally not. Restricted keyways use controlled blanks, and copies typically require authorization from the registered owner. That is a big part of the value: you control who has keys. Ask us how authorization works for the system we install on your property.
How much do high security lock installation and replacement cost?
It depends on the cylinder's security level, how many locks are involved, the condition of the door and frame, how many restricted keys you need, and whether the locks are exposed to weather. We quote after we understand the job, and we explain what is driving the cost. Call (213) 577-1366 to start.
Is rekeying enough, or do I need new high security locks?
If your locks are in good shape and you only need to cut off old keys, rekeying is usually the more economical route. If you also want to stop casual copying or add pick and bump resistance, new high security cylinders make sense. We'll tell you which you need, and our lock rekey page explains the basics.
Do you handle gates, barns, and padlocks on larger properties?
Yes. Equestrian and ranch properties often need protection beyond the front door. We can discuss weather-resistant hardware for gates, barns, and outbuildings, and we can plan the keying so you are not carrying a ring of unrelated keys. Dust and grit in this area are a real factor in choosing outdoor locks.
I rent an apartment near Foothill Boulevard. Can I install a high security lock?
Check with your landlord or property manager first. The building may be on a keyed system, and changing a lock without permission can cause problems with your lease. If the landlord approves, we can do the work and make sure the keys are handled properly.
Do you install high security locks in the middle of the night?
Our phone is answered 24 hours a day, 7 days a week. If a break-in or a lost key means you need a lock changed right away, call (213) 577-1366 and we will tell you what is possible. For planned upgrades, a daytime visit lets us examine the door in good light.
Will a high security lock protect me if my door is weak?
Not much. A strong cylinder in a warped wood door, a loose frame, or a short-screwed strike plate is still a weak entry point. We check the whole door assembly and recommend reinforcement where it is needed, since the lock is only as strong as what holds it in place.
