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 not simply a heavier-looking lock or one with a bigger price tag on the box. It is a lock built to hold up against the quiet ways people get past ordinary hardware: picking, bumping, drilling, and unauthorized key copying.
A standard pin-tumbler cylinder from a hardware store is designed to be affordable and easy to produce. It works fine for everyday use, but its tolerances are loose, its pins are plain, and its keys can be copied at almost any kiosk. A high security cylinder tightens all of that. It usually combines several of the features below.
- Security pins, such as spool and serrated pins, that make picking slower and more difficult.
- Bump-resistant design, meaning internal elements or a sidebar that do not respond to a bump key the way a standard pin stack does.
- Hardened steel inserts that protect against drilling at the points where attackers usually aim.
- A restricted keyway with key blanks that are not sold openly, so a copy requires authorization.
- A deadbolt body and strike built to resist kicking and prying, not just a cylinder that resists picking.
Why La Mirada homes and businesses upgrade their locks
Most people who call us about high security locks are not reacting to a break-in. They have noticed something small. A tenant moved out and nobody can say how many keys are still floating around. A house changed hands and the original 1950s hardware is worn smooth. A shop owner realizes that half a dozen former employees once held a key that any shop could copy.
The common thread is key control. A standard lock tells you almost nothing about who can open it, because keys are cheap to duplicate and easy to hand off. A restricted-key system changes that. When copies can only be cut with authorization, you know the number of keys in circulation is the number you actually issued.
The second reason is simple wear. Cylinders that have been in a door for decades tend to feel gritty, stick in warm weather, or need a jiggle. Replacing them with a better lock solves the annoyance and the weak point at the same time, so the upgrade often pays off in day-to-day use as well as security.
How does high security lock installation work, step by step?
We try to keep the process plain. You should know what is happening to your door and why. Whether we come out in a mobile van or you stop by the storefront in Westwood, the work follows roughly the same path.
- You call (213) 577-1366 and tell us about the door, what you are protecting, and what bothers you about the current lock. Someone answers at any hour, any day.
- We look at the door itself. Door thickness, bore size, edge condition, the strike plate, and the frame all matter. A strong lock in a weak frame is only half a solution.
- We recommend a lock and explain the tradeoffs: how much resistance you actually need, how the key system works, and what it means for spare keys later.
- We install the cylinder or the full deadbolt and strike, then adjust the alignment so the bolt throws freely without forcing it.
- We test every key, operate the lock from both sides several times, and check the latch and bolt with the door open and closed.
- We hand over the keys, explain how key authorization works for copies, and give you any registration or card information that comes with the lock so you can order more later.

Call (213) 577-1366Pick-resistant locks and bump-resistant locks: what each feature really does
These two terms get lumped together, but they address different tricks. Pick resistance is about slowing someone who is manipulating pins one at a time with tools. Security pins snag and give false feedback, and tighter machining leaves less room to work. Bump resistance is about a specific technique where a specially cut key is struck to jar the pins into place. A cylinder built to resist bumping uses different internal geometry so that trick does not line things up.
We want to be straight with you: no lock is unpickable or untouchable, and anyone who says otherwise is selling you something. What a good high security lock does is raise the skill, time, and noise required, which pushes most opportunists toward an easier door. It also leaves clearer evidence if someone tries.
Drilling and forced entry are a separate matter. That is why the deadbolt body, the hardened inserts, the strike plate, and the screws that anchor it all count. When we talk about home security locks, we are talking about the whole door assembly, not just the part you put the key in.
What affects the cost of high security lock replacement?
We do not publish numbers on a web page because the real answer depends on your door. What we can do is tell you what moves the cost up or down, so a quote makes sense when you get one.
The biggest factor is the lock itself. A high security cylinder that drops into your existing hardware is usually the more economical route compared with replacing the entire deadbolt. A full high-grade deadbolt with a reinforced strike costs more, and so does a system with a patent-protected restricted keyway and authorization controls.
- Number of locks: a front door alone is a different job than a front door, back door, and side gate.
- Cylinder only versus full hardware: some doors only need a better cylinder, others need a new bolt, strike, and reinforcement.
- Key system: matching all your locks to one key adds planning and parts, and it is often worth it.
- Door and frame condition: a warped, swollen, or poorly bored door may need adjustment before any lock performs well.
- Number of keys and spares: restricted key blanks often cost more to cut than standard ones.
- Time of day and distance: after-hours calls and longer drives affect what we charge, and we will explain that before we start.
What about commercial security locks?
Businesses have a different problem than homeowners. A home has a handful of keys. A shop, office, or warehouse may have many people coming and going, turnover among staff, and several doors that need different levels of access. A high security cylinder on the back door is only useful if you can control who holds that key.
For commercial security locks, we usually start with a conversation about who needs access to what. Sometimes a restricted keyway on a few critical doors is enough. In other cases, a master key system makes more sense, with the owner holding a top key and employees holding keys that open only their areas. If you are weighing larger hardware changes at the same time, our commercial locksmith service covers doors, hardware, and related work.
We stay in our lane on this page: this is about cylinders and key control. Panic hardware, closers, storefront repairs, and electronic access are separate jobs, and we will point you to the right one rather than stretch a lock quote to cover them.

Call (213) 577-1366High security locks in La Mirada: housing, neighborhoods, and ZIP 90638
La Mirada was master-planned and largely built out in the 1950s, and single-story ranch tract homes dominate the city. That matters for lock work. Many of those homes still carry original or early replacement hardware, and a house that has passed through a few owners can have an unknown number of keys out there. One scenario we see around town is rekeying 1950s tract homes after sales in the neighborhoods off Rosecrans Avenue. A plain rekey resets which keys work, but it keeps the same cylinder. If the buyer wants pick and bump resistance and keys that cannot be copied at a kiosk, a high security cylinder is the next step up.
Heat plays a role too. La Mirada sits slightly farther inland than neighboring Gateway Cities and runs a few degrees warmer in summer, and seasonal heat can swell wood entry doors in the older tracts. A swollen door pushes on the bolt and strike. A high security deadbolt works best when the bolt throws freely, so we check door fit and strike alignment before we finish the job. Salt-air corrosion is negligible here, which helps hardware last.
Condominium and townhome communities add another kind of stock, including the La Mirada Landmark adult community, with HOA-managed controlled-access entries. If you live in one, check your HOA rules before changing exterior locks. In a unit near La Mirada Regional Park, you may be choosing between a restricted-key deadbolt and a smart lock. Many owners do both, with a high security deadbolt as the backbone.
Homes toward the Puente Hills on the east side tend to be newer and larger than the original tracts, which often means more doors, side entries, and garage-access doors to key alike. Around Hillsborough and the Knolls at Hillsborough area, a single restricted key that runs several doors is a popular approach. Near Biola University and in the rental stock around it, landlords and tenants often want keys that cannot be casually duplicated, since turnover is steady. Along the Foster Road corridor, the Santa Gertrudes Avenue corridor, and the Creek Park area, we work on the same tract-home hardware and the same questions.
On the commercial side, retail centers along Imperial Highway and Valley View Avenue need lock service too. Rear doors, storage rooms, and office doors in those centers are where restricted keys tend to make the most sense. We serve ZIP 90638 and the adjacent unincorporated area in East La Mirada. Our storefront is at 10740 Wilshire Blvd in Westwood, about 29 miles away, so mobile vans do the field work. See our full La Mirada locksmith page for everything we do in the city.

What to check before hiring any high security locksmith
Locksmith work is a trust business, since you are handing someone access to your door. California requires locksmith companies to hold a BSIS LCO license, which is issued by the Bureau of Security and Investigative Services. Ask any locksmith for that license number before work begins, and expect a straight answer. If someone dodges, move on.
A few other signs are worth watching. A trustworthy locksmith explains what they are installing and why, can tell you whether your existing frame and strike will support it, and gives you a clear picture of how the cost works before they start drilling. They should also be clear about how restricted keys are ordered later, because a key system is only as good as your access to spares.
Be wary of anyone who promises that a lock cannot be defeated, who pushes the most expensive option without looking at the door, or who will not tell you the company name when answering the phone.
Frequently asked questions
What is the difference between a high security lock and a regular deadbolt?
A regular deadbolt mainly stops casual entry and uses a standard cylinder with plain pins and an openly copyable key. A high security lock adds resistance to picking, bumping, and drilling, and typically uses a restricted keyway so copies need authorization. Some doors need a better cylinder, others need the whole deadbolt and strike upgraded.
Can a high security lock be picked or bumped?
Any mechanical lock can be defeated by someone with enough skill, time, and tools, and we will not tell you otherwise. A good high security lock makes picking and bumping much harder, slower, and noisier, which is what discourages most attempts. It works best alongside a solid door, frame, and strike plate.
Can I get extra keys cut for a restricted-key lock?
Yes, but not at a kiosk. Restricted blanks are controlled, so copies require authorization, usually through the registered owner, a key card, or ID. We explain how that works at installation. If you need more copies, see our key duplication service or call us.
Do I need to replace the whole deadbolt or just the cylinder?
It depends on the existing hardware. If the deadbolt body is in good shape and the door is bored correctly, a high security cylinder alone is often the more economical route. If the bolt is worn, the strike is weak, or the door is damaged, a full deadbolt with a reinforced strike makes more sense. We check before recommending.
Is it better to rekey my locks or install high security locks after buying a home?
A rekey resets which keys work, which solves the question of previous owners' keys. A high security cylinder goes further by adding pick and bump resistance and controlling who can copy keys. Many new homeowners start with a rekey and upgrade the front and back doors. We can help you decide at the door.
Will hot weather affect a high security deadbolt on my La Mirada home?
Heat can swell wood entry doors, especially in the older tract homes, and a swollen door can make the bolt bind. That is a door-fit problem, not a lock problem, but it affects how any lock feels. We check door alignment and the strike when installing so the bolt throws freely in summer.
Can you install high security locks in my HOA townhome or condo?
We can, but first check your HOA rules. Many communities, including controlled-access ones, have requirements on exterior hardware, finish, and who holds master or emergency keys. Once you know what is allowed, we can fit a restricted-key deadbolt or pair it with a smart lock.
Do you do high security locks for businesses and rental properties?
Yes. For shops and offices we focus on key control: which doors need restricted keys and whether a master key system makes sense. Landlords often want restricted keys so tenants cannot copy them freely between turnovers. We can plan this with you, and you can reach us 24/7 at (213) 577-1366.
Is a locksmith required to be licensed in California?
California requires locksmith companies to hold a BSIS LCO license. Ask any locksmith for the license number before work starts and check that it is valid with the state. A reputable company will give it to you without hesitation. You can also reach us through our contact page.
