What counts as a high security lock?

The term gets stretched by packaging, so here is what we mean by it. A high security lock is built so the cylinder is difficult to defeat quietly and difficult to copy casually. That usually comes down to three things working together: the internal pin or sidebar design, the metal used in the parts attackers go after, and a restricted keyway.

A standard hardware-store cylinder relies on simple pin tumblers and a keyway that any key shop can cut. A high security cylinder adds extra security pins that resist picking, tighter manufacturing tolerances that make bumping far less effective, hardened inserts that resist drilling, and a key blank that is controlled. Controlled means a key cannot be duplicated at a kiosk by anyone holding a sample. It generally requires a card, a signature, or an authorized dealer.

When people search for pick-resistant locks or bump-resistant locks, they are usually asking for that whole package, not one feature. We install it as a package, and we tell you honestly where a given product is strong and where it is average.

  • Pick-resistant: internal design makes manipulating the pins with tools much harder and slower.
  • Bump-resistant: the cylinder is built to stay locked when a bump key is struck inside it.
  • Drill-resistant: hardened pieces protect the shear line from being drilled out.
  • Restricted keys: blanks and key cutting are controlled, so duplicates are not casual.

Why do San Fernando homes and shops ask for high security locks?

San Fernando is a compact, independent city, and a lot of its housing is old. Early-1900s bungalows, Spanish-style cottages and postwar homes on small lots often still carry original door hardware, or a hardware swap done decades ago that nobody has looked at since. That older hardware was designed for a different era. The cylinders may be worn, the keys may have been copied dozens of times by people you will never know about, and the keyway is the same common profile found on thousands of other doors.

Most of our high security calls in a city like this come from a few situations. Someone bought an older house and has no idea who holds keys. A tenant or ex-partner left and never returned a key. A shop owner has run the same keyed lock for years and wants real key control. Or a family simply wants the front door to be the strongest part of the house rather than the weakest.

None of that requires a dramatic story. A high security cylinder is an upgrade you make because the old setup has too many unknowns, and because the key itself becomes something you can actually account for.

How do we install or replace a high security lock?

High security lock installation is more careful than a basic lock swap, because the cylinder is only as good as the door it sits in. Here is how the work goes.

  1. You call (213) 577-1366 and describe the door: front door, back door, security screen door, storefront, or office. We ask what lock is on it now and what has been bothering you.
  2. We look at the door itself before recommending anything: the thickness, the condition of the wood or metal, the bore holes, the strike plate, and how well the frame holds a screw.
  3. We recommend a cylinder or full lockset that fits that door and your use. We explain the keyway, how copies are controlled, and what the lock does and does not resist.
  4. We install the hardware, reinforce the strike and frame where needed, and fit the door so the bolt throws freely without forcing.
  5. We test every key, cycle the lock repeatedly with the door open and closed, and check how it behaves when the door is slightly swollen or the latch is under light pressure.
  6. We hand over keys and any key-control paperwork, and explain how to order additional keys the right way.

Which high security lock fits which door?

Home security locks and commercial security locks overlap in technology but differ in how they are used, so the recommendation changes with the door.

On a house, the front door and any exterior door with a deadbolt are the usual starting points. Often the cleanest upgrade is a high security cylinder in a deadbolt that is already sound, or a new deadbolt installation when the existing bolt is short, loose, or poorly aligned. A pick-resistant cylinder in a weak bolt is wasted money, and we will say so.

On a storefront or office, the priorities shift. You may have many employees, a rear door that gets propped open, a glass-and-aluminum door with narrow stile hardware, or a panic exit that must always open from inside. Our commercial locksmith work covers those details, and the high security cylinder is just one piece of it. The cylinder must be compatible with the exit device and the door, or it will fail in daily use.

For apartment buildings and small multi-unit properties, key control matters even more, because turnover is higher and more people have touched a key. A restricted keyway is one of the most practical tools there.

  • Entry and back doors at a house: high security deadbolt cylinder, reinforced strike, long screws into the framing.
  • Security screen doors: a lock that matches the lighter frame, often a different product than the main door.
  • Storefront doors: cylinder compatible with the existing hardware, and a plan for who carries which key.
  • Interior offices or storerooms: restricted keys so staff cannot duplicate access casually.

How much do high security locks cost in San Fernando?

We do not quote numbers on a web page, because the real cost depends on specifics we need to see or hear about. What we can do is explain what moves the cost up or down, so there are no surprises when we give you a quote.

The biggest factor is the product itself. A high security cylinder in a lock you already own costs less than a full replacement lockset. A fully restricted system with patent-protected keys and key-control cards costs more than a cylinder with a controlled but less restricted keyway.

The second factor is the door. If the door, frame and strike are solid, the work is mostly the lock. If the wood has swollen, the frame has split, or the bolt hole is badly cut, we have to correct that or the new lock will not perform. Replacing a lock sometimes uncovers a door problem that was there all along.

Other factors are how many cylinders you want keyed alike, how many keys you need cut, and whether the job is during regular hours or an after-hours call. Mobile travel is part of it too. Our vans leave from the Westwood storefront, and San Fernando is about 23 miles from there.

For a lighter-cost route, we will sometimes suggest upgrading only the doors that matter most, or rekeying good existing hardware for now and adding high security cylinders where the risk is greatest. We give you the options and let you decide.

What does high security hardware look like around San Fernando?

San Fernando covers about 2.4 square miles, and the work varies a lot from one corner to the next. Here is how high security locks tend to come up locally, tied to the places and housing we actually see.

Near Las Palmas Park and across the older residential streets of 91340, a typical call involves a bungalow or cottage where the original hardware is still in place. Owners often start by wanting to rekey the house after a purchase. Once they see how worn the old cylinder is, or how many keys are in circulation, they decide to step up to a pick-resistant, restricted-key cylinder instead of cutting another set of common keys. We can fit it to the existing bore on many older doors, but we check wood condition first.

Heat matters here. Hot northeast-Valley summers expand wood doors and frames, so a lock that works in April can bind in August. A precision high security cylinder is less forgiving of a misaligned bolt than a loose old one, so we align the door and strike carefully. Santa Ana wind events also push dust into exterior cylinders. We advise on keeping a lock clean and dry-lubricated, and we avoid oily sprays that turn dust into paste. Winters are mild, so corrosion is rarely the issue.

Security screen doors are a common retrofit on pre-war homes in the city, and replacing a weak screen door lock with a stronger one is a fairly frequent request. The screen door is not the main barrier, but a better latch is a sensible add-on.

Along the San Fernando Mall, the Maclay Avenue corridor, and the Truman Street and San Fernando Road corridor, the situation is different. Storefronts there need locks that withstand constant use. If you run a shop, our storefront lock repair service handles failing hardware, and a high security cylinder can be added when you are ready for tighter key control. In the Civic Center area and the small apartment buildings near the downtown mall, restricted keyways help managers control who holds what.

What will a high security cylinder not fix?

We would rather tell you the limits than oversell the product. No lock is unbeatable, and a pick-resistant cylinder does nothing about the other ways a door can be defeated.

A hollow or weak door can be kicked in regardless of the cylinder. A short bolt in a thin strike can fail under force. A glass panel next to the lock can be broken. A window or sliding door elsewhere is often easier than your front door. A key left under a mat, or a spare given to someone you do not know well, defeats even the best keyway.

So a good job treats the lock, the door, the frame, and the key habits as one system. When we visit, we point out weak points we can see, even when fixing them is not part of the work you called us for. You decide what to do about them.

Restricted keys also come with a trade-off. They are harder to copy, which is the point, but it means extra keys cost more effort and take longer to get. If you regularly hand out keys to family, cleaners or contractors, we will plan for that before installing so you are not caught short.

How do restricted keys and key control actually work?

With a restricted key system, the key blanks are not sold freely. The manufacturer or authorized dealer controls who can order them, usually through a registered account or an authorization card. That is what makes copies traceable.

For a household, this can be simple: one owner or a short list of authorized people. For a business, it can be more detailed, with different people holding different keys. If you need one key to open several doors, or a hierarchy where managers can open more than staff, that is a master key system, and it is worth designing before you buy cylinders so that everything is keyed from the start.

We can explain how additional keys are ordered in your system and set up your paperwork accordingly. For ordinary keys on non-restricted locks, our key duplication service handles those separately.

One practical tip: when you receive restricted keys, write down where the key-control card is stored and who is authorized. Losing that card is the most common headache in these systems, and it is easy to prevent.

Why call Wilshire Lock & Key for high security locks?

We have been in business since 1987, and we work from a real storefront at 10740 Wilshire Blvd in Westwood, with mobile service vans that cover 140 cities across Los Angeles and Ventura counties, San Fernando included. You are dealing with one company, not a call center passing your job to whoever is available. Our phone, (213) 577-1366, is answered 24 hours a day, 7 days a week, all year.

David, the owner and lead technician, oversees the work. High security installs depend on small decisions: which cylinder, how it sits, how the strike is set. Those are the decisions he pays attention to.

California requires locksmith companies to hold a Bureau of Security and Investigative Services (BSIS) Locksmith Company (LCO) license. You should ask any locksmith you call for their license number before work starts, and you should expect a straight answer. That is a fair request from any customer.

If you are locked out or have a broken lock tonight, we handle that too through our emergency locksmith service. If you are replacing a failed lock rather than upgrading a good one, our general lock replacement page explains that process.

Frequently asked questions

What is the difference between pick-resistant and bump-resistant locks?

Pick-resistant refers to internal features that make manipulating the pins with picking tools difficult. Bump-resistant means the cylinder is designed so that striking a bump key does not release it. Most quality high security cylinders address both, plus drilling. We tell you which of these a specific product handles well before you buy it.

Can you put a high security cylinder in my existing deadbolt?

Often yes, if the deadbolt is in good shape and the cylinder type is compatible. If the bolt is short, loose, or worn, we recommend replacing the whole deadbolt, because a strong cylinder in a weak bolt does not do much. We check this at the door before suggesting anything.

Will high security locks work on an older San Fernando bungalow?

In most cases they can. Many older homes here still have original hardware and wood doors, and we can fit modern cylinders or locksets to them. We check the wood, bore holes and frame first, since older doors sometimes need a repair or a reinforced strike for the new lock to perform properly.

Do I need a high security lock for a security screen door?

It is not essential, because the main door is the real barrier. Still, many pre-war homes here have weak screen door latches, and upgrading to a sturdier one is a reasonable improvement. We match the lock to the lighter screen door frame rather than forcing in a heavy product that does not fit.

Can any locksmith copy a restricted key?

No, that is the idea. Restricted blanks are controlled, so duplicates generally require authorization from the account holder or a registered dealer. It adds some inconvenience when you need extra keys, but it is also what keeps unknown copies from circulating.

How do I upgrade a storefront on the Mall or Maclay Avenue?

Start by telling us what hardware is on the door now and whether it includes a panic bar or closer. The cylinder has to work with that hardware. We can add a high security cylinder to compatible commercial hardware, and we can set up a key plan for staff. Failing hardware may need repair first.

Is rekeying enough, or do I need high security locks?

Rekeying changes the key so old keys stop working, which solves the problem of unknown keys. It does not make the cylinder harder to pick or bump. If the existing lock is good, rekeying may be the more economical route. If you want resistance to picking and controlled copies, a high security cylinder is the better fit.

Can you install high security locks after hours or on weekends?

Yes. Our line at (213) 577-1366 is answered around the clock, every day of the year. For urgent situations we can secure the door first and handle a full high security upgrade at a calmer time, so the work is not rushed.

How do I check that a locksmith is legitimate?

California requires locksmith companies to hold a BSIS Locksmith Company (LCO) license. Ask for the license number before the work starts, and be cautious if the company will not give it or will not tell you where it is based. A real storefront and a clear phone number are also good signs.
