What actually makes a lock a high security lock?
The phrase gets used loosely, so here is what we mean by it. A high security lock is a lock built to resist the common ways people get through a door without the key. That usually comes down to the cylinder, the part your key turns, and to how tightly the company controls who can make copies of that key.
A standard pin-tumbler cylinder from a hardware aisle can often be picked by someone with basic tools and a little practice, and many can be bumped with a specially cut key. A high security cylinder changes the internal design so those methods get much harder. It also tends to use tougher materials in the places a drill or a pry tool would attack.
When customers ask for pick-resistant locks, bump-resistant locks, or home security locks, they are usually asking for some mix of these features:
- Pick resistance: extra or oddly shaped internal parts that make manipulating the lock with picks slow and unreliable.
- Bump resistance: internal designs that defeat the tap-and-turn technique that works on many ordinary cylinders.
- Drill and pry resistance: hardened inserts and sturdier housings around the weak points.
- Restricted keys: blanks that are not sold over the counter and cannot be copied without authorization, so a key does not end up duplicated without your knowledge.
- Tested ratings: an ANSI/BHMA grade for the lock body, and for some cylinders, a UL 437 listing for resistance to picking, bumping, and forced attack.
Why Inglewood homes and buildings ask about high security locks
Inglewood has a wide range of buildings, and people come to us for different reasons. In the older Spanish bungalows and postwar stucco homes, the original lockset is often decades old and has been keyed to a long list of past tenants, relatives, and contractors. In the apartment stock, doors may have been rekeyed several times by different people with no record of who holds which key. In newer condominium and apartment buildings, the front door may look modern while the cylinder inside is basic.
The common thread is that the lock is the part everyone assumes is doing its job, and nobody has checked it. A high security cylinder is a way to answer a specific worry: that a key has been copied somewhere you cannot trace, or that the lock is easy to defeat quietly.
We try to be straight about what these locks do and do not do. A better cylinder makes covert entry much harder. It does not make a weak door frame strong, and it does not fix a loose strike plate. We look at the whole door before recommending anything, because spending on a cylinder while the frame is the real weakness is poor value for you.

Call (213) 577-1366How do we install or replace a high security lock?
Whether you want a high security lock installation on a door that has never had one, or a high security lock replacement for a cylinder you have outgrown, the process is similar. David oversees how we approach it, and we keep it simple.
- You call (213) 577-1366, any hour. We ask what the door is (front, back, security screen door, storefront), what lock is on it now, and what worries you most.
- We inspect the door in person, since the answer depends on the door. We check the cylinder, the deadbolt or latch, the strike plate, the screws that hold it, and the frame around it.
- We recommend a setup that fits the door and the concern. That might be a high security cylinder in your existing hardware, a new deadbolt with a high security cylinder, or both.
- We explain key control options. If you want restricted keys, we explain how the authorization works, who can request copies, and what happens if you lose one.
- We install the hardware, align the bolt and strike so it throws cleanly, and fit the reinforcement the door needs.
- We test the lock with you, cycle every key, and show you how it behaves so you know what normal feels like. You receive your keys and the information you need for ordering copies later.
Pick-resistant versus bump-resistant: what each one protects against
These terms get mixed up, and the difference matters when you compare options. Picking is manipulating the pins with tools, one at a time or in sequence. Bumping uses a cut key that is struck to jolt the pins into position. A lock can resist one method better than the other, and a properly built high security cylinder is designed to resist both.
What neither does is stop a person who goes around the lock. Kicking a door, prying a frame, or breaking a nearby window are all separate problems. This is why we often pair a cylinder upgrade with a proper deadbolt, a reinforced strike plate, and long screws that reach the framing. If you are adding a new bolt as well, our deadbolt installation service covers that side of the door.
Security screen doors and window bars are common on older homes and smaller apartment buildings in Inglewood's denser corridors. They add a layer, but the lock on a security door is often a basic one, and it can be the easiest part to defeat. If you already have a screen door, we can look at its lock as part of the same visit.

Call (213) 577-1366What affects the cost of high security lock installation?
We do not quote numbers on a web page, because the real price depends on your door and your choices. Here is what moves the cost up or down so you can plan ahead.
Rather than hand you a vague range, we give you a clear figure once we know what you are buying, before work begins. A few of the bigger factors:
- The cylinder itself: tested, patented, restricted-key cylinders cost more to make than standard ones, and the level of protection varies by product.
- How many cylinders: one front door is a different job from a front door, back door, side gate, and garage entry that you want on the same key.
- Whether the hardware underneath is sound: if the existing deadbolt or latch is worn, it is usually wiser to replace it than to put a good cylinder in a poor body.
- The door and frame: reinforcement, a new strike plate, or work on a damaged frame adds time and parts.
- Key control: restricted keys, extra copies, and any record-keeping you want for a building with many users.
- Timing and location: after-hours calls and travel to your address can factor in, and we explain that up front.
- Rekeying versus replacing: when a lock only needs new keys, lock rekeying is usually the more economical route, but it does not upgrade the cylinder's resistance to picking or bumping.
High security locks across Inglewood: neighborhoods, ZIP codes, and real situations
We serve all of Inglewood, from ZIP 90301 through 90305, and we are about 11 miles from our Westwood storefront. Our mobile vans carry the hardware, so most of this work happens at your door.
In Fairview Heights and Morningside Park, many homes are 1920s to 1940s Spanish bungalows. The doors are often solid and worth protecting, but the original hardware may be mortised or old enough that fitting a modern cylinder takes careful judgment. A typical request there is a gate or security-door lock that needs to be stronger. Gate and security-door lock repair on Morningside Park bungalows is a regular scenario, and when the lock is simply too easy to defeat, replacing it with a pick-resistant one makes more sense than repairing it again. For a gate that needs mechanical repair rather than an upgrade, see our gate lock repair page.
Along Century Boulevard and the La Brea corridor, there is a lot of rental housing, and most Inglewood residents rent. That affects how we approach it. A tenant typically cannot swap a cylinder without the owner's permission, so we often work with property owners who want restricted keys and a clear record of who holds them. Those owners and managers can read more about locksmith services for landlords.
In Downtown Inglewood, storefronts on Market Street are a different case from homes. A shop door gets opened and closed many times a day, so the lock needs to be both tough and durable. Our commercial security locks work covers that, and when a front door needs wider repair, we cover it on the storefront lock repair page.
The newer Hollywood Park buildings near SoFi Stadium are adding condominiums and apartments. Many of those have electronic locks. A smart lock changes how you open the door, but it still has a physical side, and we are glad to talk through that. Our smart lock installation page covers that service.
The climate here is mild. Inglewood is a few miles inland, so marine-layer mornings are common but salt exposure is low, and weather has only a modest effect on door hardware. That means long service life from a good cylinder, and you do not have to choose special coatings.

Call (213) 577-1366Commercial security locks versus home security locks
The technology overlaps, but the priorities differ. A home door needs strong protection and a key that is comfortable to use every day. A business door often has more people with keys, longer hours, and more at stake if a key goes missing.
For a shop, office, or small commercial space, the usual concerns are key control and durability. A restricted keyway means an employee cannot take a key to a kiosk and have it copied. If someone leaves the business, we can talk about whether a new cylinder or a rekey makes sense. Where several doors should work from one key, a master key arrangement can be part of that conversation, and we can set it up around your layout.
For residential customers, the question is often simpler: do I want the front door to be harder to defeat than the one next door? We lay out the options plainly and let you decide where to spend.

What should you ask any high security locksmith?
High security work involves your safety, so it pays to check who you are hiring. California requires locksmith companies to hold a license from the Bureau of Security and Investigative Services, known as a BSIS LCO license. Ask any locksmith you consider for that license number, and check it with the state. This is good practice for any company, including ours.
A few more questions are worth asking:
- What exact cylinder are you proposing, and what is it tested to resist?
- How are restricted keys controlled, and what happens when I need another copy?
- Will you check the door, frame, and strike plate, not just swap the cylinder?
- Do you tell me the total before work starts, and what could change it?
- Who will actually do the work?
Frequently asked questions
What is the difference between a high security lock and a regular deadbolt?
A regular deadbolt mostly describes the bolt that locks the door. A high security lock refers to a cylinder and body designed to resist picking, bumping, drilling, and unauthorized key copying. You can have a deadbolt with a standard cylinder or one with a high security cylinder. The bolt matters, but the cylinder is where the added protection usually comes from.
Are pick-resistant and bump-resistant locks really different?
They are different methods of attack, and a lock can resist one better than the other. A good high security cylinder is designed to resist both. We tell you what the specific cylinder is built to handle, so you are not relying on a general label.
Can a high security lock still be broken into?
Yes, any lock can be defeated with enough force or time. A high security lock makes quiet, covert entry much harder, but it will not help if the door frame is weak or the strike plate is loose. That is why we look at the whole door and do not just replace a cylinder.
What are restricted keys and why do they matter?
A restricted key uses a blank that is not sold freely, and copies need authorization. This helps if you want to keep track of who holds a key, which matters in rentals, shared buildings, and businesses. If you ever need more keys, the process runs through us or whoever you have authorized, not a self-serve kiosk.
Can you upgrade the lock on my Inglewood bungalow without replacing the whole door hardware?
Often, yes. Many existing deadbolts can accept a high security cylinder if the body is in good condition. If the hardware is old or worn, it can make more sense to replace it too. We check on site, because older doors vary and we would rather tell you what fits than force something.
I rent my apartment. Can I install a high security lock?
Check with your landlord or property manager first, since most leases restrict changes to locks. If the owner agrees, we can do the work, and we also work with owners who want a better cylinder and clear key control across a building.
How much does high security lock installation cost in Inglewood?
It depends on the cylinder you choose, how many doors you want done, the condition of the existing hardware and frame, how you want keys controlled, and the time of day. We do not post figures online. We give you a clear total once we have seen your door and before any work begins.
Do you handle high security locks for businesses on Market Street?
Yes. Commercial security locks are part of what we do, including restricted key systems and durable cylinders for doors that are used heavily. We look at the door, the traffic it gets, and who needs keys, then recommend a setup.
Can I get service at night or on a weekend?
Yes. We answer the phone 24 hours a day, 7 days a week, year-round at (213) 577-1366. If you have a lock concern after hours, call and we will talk through what you need.
