What makes a lock high security, and what doesn't?
A high security lock is built to resist the ordinary ways a lock gets beaten: picking, bumping, drilling, and copying a key at a hardware-store kiosk. Most of that work happens inside the cylinder, the part your key slides into, and in the bolt and strike plate behind it. A standard builder-grade cylinder uses simple pin tumblers with loose tolerances. A high security cylinder tightens those tolerances, adds security pins or a second locking element, and pairs the whole thing with a restricted key.
Three things separate real high security hardware from a box that just has the phrase printed on it. The first is the cylinder design. The second is key control, meaning who is able to make a copy of your key. The third is the bolt hardware and how it is anchored to the door and frame. If any one of the three is weak, the whole setup is weaker than it looks.
We have been doing this work since 1987, and the most useful thing we can tell you is that no lock is unpickable or unbreakable. High security hardware raises the time, skill and noise needed to defeat a lock, and it takes the easy, quiet methods off the table. That is a real benefit, and it is the honest way to describe it.
- Cylinder: tighter machining, security pins such as spool or serrated types, and sometimes a sidebar or a second set of pins that has to line up at the same time.
- Key control: a restricted keyway and patent-protected key blanks, so copies are made only through an authorized process rather than at a self-serve machine.
- Hardware: a solid deadbolt with a hardened bolt, a reinforced strike plate and long screws that reach the framing, not just the thin jamb.
Why do Lancaster homes and businesses ask for pick-resistant locks?
People call us for high security locks for a handful of ordinary reasons. Some have had a break-in or an attempted one and no longer trust the lock that was on the door. Some have moved into a house where nobody knows how many copies of the old key exist. Some run a business where employees come and go, and some simply own a property with a lot of valuable equipment and want the door to be the hardest part of the building to deal with.
A pick-resistant cylinder answers the person who can open a basic lock quietly with simple tools. A bump-resistant design answers a different method, where a specially cut key is struck to jump the pins. A restricted key answers the quieter, more common problem: a key that was copied years ago by someone you will never identify. Many people are surprised that the key-control part ends up mattering as much as the picking resistance.
If you are not sure which of those problems you actually have, that is a fine place to start. Describe the door, who has keys and what worries you, and we will tell you plainly which features are worth paying for and which are not.

Call (213) 577-1366How does high security lock installation work, step by step?
Whether it is a first-time installation or a high security lock replacement on a door that already has hardware, the process is the same. We do not sell a one-size-fits-all package, because the door in front of us decides a lot of the answer.
- You call (213) 577-1366 and tell us what the door is, what lock is on it now, and what you want to protect. If it is a full emergency, such as a door that will not secure after a break-in, we treat it that way.
- We look at the door and frame, either on site with a mobile van or from your description first. We check the door material, the thickness, the backset, the strike plate and the condition of the jamb.
- We recommend the cylinder and deadbolt that fit the door and your key-control needs, and we explain what each feature does and does not protect against. You get the choices and the cost drivers before any work starts.
- We remove the old hardware, fit the new cylinder and bolt, and reinforce the strike and jamb where they are the weak point. If the door has swollen or shifted, we fix the alignment so the bolt throws freely.
- We test the lock from both sides, cut and test your keys, and walk you through how the restricted key system works, including how to order additional keys later.
- We leave you with your keys and any key-card or authorization paperwork that comes with a restricted system, so you can order copies without a hassle.
Pick-resistant, bump-resistant and restricted: what each term really means
These words get used loosely, so here is how we use them. Home security locks and commercial security locks can both be built around any of these features, and the good ones combine several.
- Pick-resistant locks use security pins, tighter tolerances or extra locking elements, so a pick has to deal with false feedback and more steps than in a standard cylinder. They slow a skilled person down and defeat an unskilled one.
- Bump-resistant locks use designs that do not respond to the impact of a bump key. That can be a sidebar, a different pin arrangement or a second locking mechanism. A lock marketed as bump-resistant is only as good as its design, which is why we explain which method it uses.
- Restricted keys are cut on blanks that are protected by patent or by a controlled distribution system. Duplicates require authorization, which is the point. It keeps a former tenant, contractor or employee from having a copy made without your knowledge.
- Drill and attack resistance is separate. It involves hardened inserts and the bolt itself, and it is part of what you see when a cylinder or deadbolt carries a recognized rating from standards bodies such as UL or the ANSI/BHMA grading. We tell you which rating a specific product carries before it goes on your door.

Call (213) 577-1366What affects the cost of high security lock replacement?
We do not quote a number on a web page, because the same phone call can describe two very different jobs. What we can do is tell you exactly what moves the cost, so you can see why a quote is what it is.
The biggest factor is the cylinder and key system you choose. A restricted, patent-protected system costs more to produce and to key than a standard one, and the more of the protective features you want, the more that holds true. Next is the number of locks. A single front door is one job. A house with a front door, a back door and a garage entry, all keyed alike on a restricted system, is another. After that comes the condition of the door and frame. A solid door in good shape means a clean installation. A warped door, a split jamb or a cheap strike plate means extra work to make the new lock actually perform.
Timing and location also play a part. A scheduled installation is the usually more economical route compared with an after-hours call-out, because we can plan the visit and bring the exact parts. Lancaster is about 67 miles from our Westwood storefront, so we plan the trip around your job. And if the work is urgent, we will tell you what changes, but we will not hide it.
One more cost note: ordering extra keys on a restricted system takes more steps than copying a standard key. That is by design, but it is worth ordering the spare copies you need at the time of installation.
- The cylinder and key system you choose, and how many security features it includes
- How many doors or locks are being replaced, and whether they are keyed alike
- The condition and material of the door and frame, including any repair or reinforcement needed
- Whether the visit is scheduled or an after-hours call-out
- Whether we need to source a restricted key blank or hardware that is not on the van
How do high security locks work in Lancaster's housing and desert climate?
Lancaster has a real mix of housing, and each type asks something different of a lock. In older central and east Lancaster, where many 1950s to 1970s ranch homes sit on grid streets, we see original hardware that has been through decades of wind and dust. A common request in those neighborhoods is a deadbolt upgrade alongside a security screen door, and a pick-resistant cylinder is a sensible place to start when nobody knows how many old keys are floating around. Households in East Lancaster, Lincoln or Mariposa often tell us exactly that: the house changed hands once or twice and the key count is unknown.
On the westside, ZIP 93536 is dominated by larger 1980s to 2000s stucco tract homes, and the story there is different. These houses usually have several entry points, and families often want one restricted key system that works on the front door, the side door and the garage entry. A lockout call in the west Lancaster tracts near Avenue K and 30th Street West is often the moment someone realizes how loosely their locks were keyed, and it is a natural time to talk about an upgrade after the door is open.
Downtown Lancaster and The BLVD district bring apartments and storefronts, and the lettered avenues carry plenty of multi-unit buildings. Up in Desert View and out toward Quartz Hill and Antelope Acres, the large-lot rural properties add outbuildings and gates to the lock list. For gate hardware that has been chewed up by dust, see our gate lock repair page.
The desert itself is the part people forget. At about 2,350 feet, Lancaster has triple-digit summer heat, sub-freezing winter nights and strong winds that carry fine dust. Doors and frames expand and contract through those swings, and a door that sticks in July can bind a deadbolt that was fine in January. Dust gets into outdoor cylinders and gate hardware. High security cylinders have tight tolerances, so we check door alignment at installation and recommend a dry lubricant rather than oil, which holds dust. Keep that in mind in 93534 and 93535 as much as in 93536: the climate is the same across all three.

Call (213) 577-1366Commercial security locks and key control for Lancaster businesses
For a business, the most valuable feature of a restricted system is usually key control, not picking resistance. Employees leave, contractors come and go, and a standard key can be duplicated by anyone. A restricted key system means the owner decides who can authorize a copy, and the records show who holds what.
Industrial and warehouse buildings along Sierra Highway and Division Street are a good example. Those buildings often have a mix of overhead doors, personnel doors and office entries, and keys have usually spread over the years. We can re-key or replace those cylinders on a restricted system and organize them under a hierarchy so that one key opens what an owner needs it to. If you want that structure, our master key system work goes into the details.
Storefronts along The BLVD have a different problem. Glass doors, narrow stiles and heavy daily use mean the lock has to fit the door, and a pick-resistant cylinder is only worth it if the hardware and closer around it are sound. We keep the focus on the cylinder, and we will tell you if the surrounding hardware needs a separate repair first.
If you need a high security locksmith for a commercial property, tell us how many doors, how many people carry keys and whether the building has a master system already. Those three answers shape the plan.
Why call Wilshire Lock & Key for high security locks?
High security hardware is a place where the installer matters. A good cylinder badly fitted is a mediocre lock, and a poor installation can leave a restricted-key door with a weak frame. Here is what we can honestly offer.
We have been in business since 1987, working from a storefront at 10740 Wilshire Blvd in Westwood, with mobile service vans that reach 140 cities across Los Angeles and Ventura counties, Lancaster included. The phone at (213) 577-1366 is answered around the clock, every day of the year. When you call, you reach our company, not a call center that sells your job to whoever picks it up. The technician who comes is part of our team, not a subcontractor you have never heard of.
David, the owner and lead technician, oversees the work. That matters most on installations where the right decision is not the most expensive one. Sometimes a rekey is the sensible choice instead of a full replacement, and we will say so; see our lock rekey page for how that works.
One last point on trust: California requires locksmith companies to hold a BSIS LCO license, and you should ask any locksmith you hire for it. Do not hesitate to ask us the same questions you would ask anybody working on your front door.

Call (213) 577-1366When a different service fits better
Not every lock problem calls for high security hardware. If your current lock works and your only concern is a lost key, a rekey may be the usually more economical route; it changes the pins so old keys stop working. If the lock is worn out, failing or damaged, a standard lock replacement may meet your needs. If you want an extra deadbolt on a door that has none, start with deadbolt installation and add the restricted cylinder at the same visit.
If you are locked out right now, that is a separate problem and we handle it first. Call us and our emergency locksmith service will get you in, and we can talk about an upgrade afterward when you are not standing in the driveway.
And if you already own restricted keys and need duplicates, our key duplication page explains why those copies need authorization. For anything you would rather schedule at your property, our mobile locksmith service comes to the door.
Frequently asked questions
Are high security locks really pick-proof?
No lock is pick-proof, and anyone who says otherwise is selling something. High security locks are pick-resistant: they use security pins, tight tolerances and sometimes a second locking element so that picking takes much more skill, time and noise than a standard cylinder. They remove the easy, quiet methods, which stops most attempts.
What is the difference between a pick-resistant and a bump-resistant lock?
Pick-resistant refers to resistance against manipulating the pins with picking tools. Bump-resistant refers to resistance against a specially cut key that is struck to jump the pins. Many high security cylinders address both, but the designs differ, so we explain which method a particular lock uses before you decide.
What is a restricted key and why does it matter?
A restricted key is cut on a blank protected by patent or by a controlled distribution system, so copies need authorization. It matters because it stops a former tenant, employee or contractor from having a copy made without your knowledge. For many Lancaster homeowners and businesses, that key control is the biggest benefit.
Can you install high security locks on my existing door?
Usually yes, but the door and frame decide how well the lock performs. We check the door material, thickness, backset, strike plate and jamb. If the frame is weak or warped, we reinforce or align it so the new lock actually does its job. Sometimes that means repair work first.
How much do high security locks cost in Lancaster?
We do not quote numbers online because the answer depends on the cylinder and key system, how many doors you have, the condition of the door and frame, and whether the visit is scheduled or after hours. Call (213) 577-1366, describe the doors, and we will explain the cost drivers and your options.
Will Lancaster's dust and heat affect a high security cylinder?
Dust and temperature swings affect every lock. High security cylinders have tight tolerances, so we check door alignment at installation, since a door that swells in summer can bind a bolt. We also recommend a dry lubricant rather than oil, which holds dust. Outdoor gate hardware needs more frequent attention.
Can you make extra keys for a restricted system?
Yes, but through the authorization process that comes with the system. That is intentional, since it keeps copies from being made casually. We suggest ordering the spare keys you need at the time of installation, because getting more later takes extra steps and sometimes extra lead time.
Do you handle high security locks for businesses as well as homes?
Yes. For commercial buildings the focus is usually key control, with restricted keys and sometimes a master key hierarchy. We work with storefronts, offices and industrial buildings. Tell us how many doors and who carries keys, and we will recommend a system that fits.
Do you serve Lancaster at night and on weekends?
Our phone line at (213) 577-1366 is answered 24 hours a day, seven days a week, all year. If you are locked out or a door will not secure, call right away. Planned installations are easier to schedule and often the more economical route.
