What actually makes a lock a high security lock?
A standard deadbolt from a hardware-store shelf is a perfectly good lock for keeping a door closed. What it usually lacks is resistance to the quiet ways a lock gets beaten: being picked, being bumped, or being opened with a key that someone copied years ago and nobody tracked. A high security lock is built to make those routes harder, and it does that with specific design features rather than a heavier-looking case.
It is worth being straight about the limits. No lock is unpickable, and anyone who tells you otherwise is selling something. What a good high security cylinder does is raise the skill, time and noise required to get past it, and it controls who can make keys. For most homes and shops, that shift is the whole point.
- Pick resistance: tighter tolerances, security pins and extra internal locking elements that make manipulation far more difficult than on a basic cylinder.
- Bump resistance: internal designs that don't respond to a bump key the way an ordinary pin-tumbler cylinder does.
- Key control: restricted keyways and protected key blanks, so a copy can only be made through an authorized channel instead of a kiosk or a neighbor's shop.
- Drill and force resistance: hardened inserts and sturdier cylinder bodies that hold up better against physical attack.
- Build grade: look for commercial-grade hardware, such as ANSI/BHMA Grade 1 deadbolts, rather than light residential-grade bodies.
Why do Canoga Park homes and businesses ask for high security locks?
Canoga Park began as Owensmouth in 1912, and the housing reflects that long history. The core still has early-20th-century bungalows, surrounded by a majority of single-family tracts built in the 1940s through the 1960s. Many of those doors have had the same lock cylinder for decades, and nobody knows how many keys are floating around: former tenants, old roommates, contractors, a relative who moved away. When a property has changed hands or a rental has turned over, the question is rarely 'is this lock broken' but 'who else can open it.'
That question is exactly what restricted keys answer. With a conventional cylinder, any copy shop can duplicate a key in a minute. With a restricted system, the blanks are controlled, and copies require authorization from whoever holds the key records. For a landlord, a shop owner, or a homeowner who simply wants to know the key count, that control is often worth more than any single feature of the lock body.
Businesses come to us for a slightly different reason. A storefront or warehouse sees more keys, more employees and more turnover than a house. A high security cylinder, paired with a sensible key plan, keeps a former employee's old key from staying useful forever.

Call (213) 577-1366How do we handle a high security lock job, step by step?
Whether it's one front door or a row of suites, the process is the same. We'd rather spend a few minutes on the front end than put an expensive cylinder into a door that can't support it.
- You call (213) 577-1366, any hour, and talk to us about the door, what is on it now and what worries you. Our mobile vans come out to Canoga Park from our Westwood storefront.
- We look at the door, frame, strike plate, hinges and existing hardware before recommending anything. A high security cylinder is only as strong as the door it sits in.
- We explain your realistic options: a high security cylinder in your existing hardware, a full high security deadbolt, or a restricted-key system that covers several doors.
- We talk through key control: how many keys you need, who will hold them, and who may authorize copies later.
- We install the hardware, align the bolt and strike so it throws smoothly, and fix any frame weakness that would undercut the lock.
- We test the keys and the lock together with the door open and closed, hand you the keys and any key-control paperwork, and explain what to do if a key goes missing.
Which high security lock fits a house, and which fits a shop?
Home security locks and commercial security locks overlap, but the priorities differ. A house usually needs a strong deadbolt, a restricted key and good door reinforcement. A shop or warehouse often needs the same plus the ability to manage many keys in a clear hierarchy.
- Front and back doors at a home: a pick-resistant, bump-resistant deadbolt with a restricted keyway is the most common choice. Good if you want to know exactly who can copy your key.
- Garage entry and side doors: these often get forgotten. Matching them to the same keyed-alike high security system means one key instead of a ring of them.
- Retail doors near busy centers: commercial security locks with robust bodies and key control suit doors that open and close many times a day. If you need different staff to open different doors, a master key system can be built on top of a restricted keyway.
- Warehouses and shared facilities: heavier-duty cylinders and hardened hardware matter more than appearance. Our commercial locksmith work covers the door hardware around the lock too.
- Apartment entries: the unit door and any shared-entry hardware have different needs. We'll explain which one benefits from a high security upgrade and which just needs sound basics.

Call (213) 577-1366Should you rekey, upgrade, or fully replace?
Not every situation calls for brand-new hardware. If your current lock is a decent-quality deadbolt that works smoothly and you simply want new keys, a lock rekey is usually the more economical route. It changes the internal pins so old keys stop working, but it does not make the lock more pick-resistant or bump-resistant than it already was.
If the concern is how the lock resists manipulation, or you want key copies controlled, rekeying alone won't get there. That calls for a high security cylinder or complete high security lock replacement. We'll tell you plainly which category you're in. If a rekey does the job, we'll say so instead of selling more than you need.
- Rekey: new keys, same lock. Good for move-ins and tenant turnover on solid existing hardware.
- Cylinder upgrade: swap in a high security cylinder while keeping compatible hardware and the existing door preparation.
- Full replacement: right when the lock body is worn, low-grade, or a poor match for the door.
What affects the cost of high security lock installation?
We don't quote numbers on a web page because the honest answer depends on the door in front of us. Here is what moves the cost up or down, so you know what you are being asked to pay for.
The lock itself is the biggest variable. Pick-resistant, bump-resistant cylinders with patented key control cost more to manufacture than basic cylinders, and different systems carry different levels of protection. The number of doors matters too, since keyed-alike or master-keyed systems need planning and extra cylinders. Key quantity, restricted blanks and any authorization paperwork add to the total.
Next is the door and frame. If the door is solid and the frame is sound, installation is straightforward. If the strike area is split, the bore is oversized, or the door has warped, additional work is needed so the lock functions properly. Finally, timing plays a part: an after-hours emergency visit is different from a scheduled daytime install. We give you the full picture before work starts so there are no surprises.
Why does the door and frame matter as much as the lock?
People often spend on a strong cylinder and ignore what it is mounted in. A pick-resistant lock in a hollow, splintered frame is still a weak door. We check the strike plate, the screws that hold it, the jamb behind it and the hinge side. Longer screws into the framing and a reinforced strike are inexpensive additions that make a real difference.
Canoga Park's climate adds a wrinkle. The far West Valley has long, hot summers with frequent triple-digit stretches, and dry Santa Ana wind events in fall. Repeated heat cycles can swell and shrink wood doors and frames, gradually pulling deadbolt and strike alignment out of true, especially in older homes. A bolt that drags or only half-engages wears the cylinder and tempts people to leave the door unlocked. Before we install a high security lock on an older wood door, we check that the bolt throws freely and, if needed, correct the alignment. Our deadbolt installation work follows the same rule: smooth operation first, then strength.

Call (213) 577-1366What does high security lock service look like around Canoga Park?
Canoga Park is a mix of older homes, apartment corridors and working commercial streets, and the high security question looks different on each. Here is how it tends to play out in specific parts of the community, drawing only on the area's known layout.
In the Owensmouth historic district and the bungalow streets around it, doors are often original or old wood, with decades of unknown key history. A high security deadbolt with a restricted key gives a new owner or long-time resident a clean slate, as long as the door and frame are in good shape. Out in the 1950s tract neighborhoods in ZIP 91303 and 91304, rekeying after move-ins or tenant turnover is common, and some owners decide to go a step further and move to restricted keys so copies don't multiply again.
Along Sherman Way, Vanowen Street and Roscoe Boulevard, older multifamily buildings commonly use security screen doors and shared-entry hardware. For a landlord managing several units, a restricted-key system helps control who can duplicate a unit key. If you own rentals, see our page for locksmith services for landlords. Tenants locked out of those buildings are a separate matter, and we handle them as lockouts, not upgrades.
Downtown Canoga Park along the Sherman Way corridor has storefronts where doors open all day. Near the Westfield Topanga area, shops need retail master-key and rekey work, and a restricted keyway under a master-key plan keeps staff keys from being casually duplicated. Along the De Soto Avenue industrial corridor, warehouses need commercial lock service where heavier cylinders and hardened hardware make sense. Whichever you are, we look at the door and the key plan together.
What happens with restricted keys if you lose one or need more?
Restricted keys are the main benefit of a high security system, and also its main inconvenience. A kiosk can't copy them, so extra keys come through an authorized process. We tell you how it works before you commit, because it's better to know now than at midnight with a missing key.
Depending on the system, copies require the key card, a signature from the registered owner, or an order through the manufacturer's channel. Some blanks are not kept on the shelf and have to be ordered, so we'd encourage you to order the keys you need up front. If you need ordinary duplicates for lower-risk doors, our key duplication page explains what we can copy and what we can't.
If you lose every key to a high security lock, call us. We can usually get you in without damaging the door, and then sort out new keys. A lockout in the middle of the night is the kind of thing our emergency locksmith line is for, since we answer 24 hours a day.

Call (213) 577-1366Why call Wilshire Lock & Key for high security locks?
We have been in business since 1987, and that history shows up in how we work. David, who owns the company and is its lead technician, oversees the work. You deal with one company, not a call center that passes your job to whoever is free. We have a storefront at 10740 Wilshire Blvd in Westwood plus mobile service vans, so we can bring the tools and cylinders to Canoga Park, about 21 miles from our base, and do the job at your door.
We answer the phone around the clock, every day of the year, at (213) 577-1366. We serve 140 cities across Los Angeles and Ventura counties, so we're used to a broad mix of door types and building ages.
One more point on trust. California requires locksmith companies to hold a BSIS LCO license, and you should ask any locksmith for that license number before they start work, then verify it with the state. It's a reasonable question and a good habit, whoever you hire. Ask us about anything else too: the hardware, the key-control process, what the job involves.
Frequently asked questions
Are pick-resistant locks truly pick-proof?
No. No lock is pick-proof. Pick-resistant locks use tighter tolerances, security pins and extra locking elements so that picking takes much more skill and time than on a basic cylinder. They make the easy routes harder, which is what matters in practice.
What is the difference between pick-resistant and bump-resistant locks?
Picking is manipulating the internal parts one at a time with tools. Bumping uses a specially cut key and a sharp strike to jar the pins. A good high security cylinder is designed to resist both, but the internal features that do so are different, so we explain which protections a particular cylinder offers.
Can you put a high security lock on my existing door?
Often yes. We check the door's bore, thickness, frame and strike area first. If the door is sound, a high security cylinder or deadbolt usually fits. If the door is warped, split or poorly prepared, we correct it first or explain what needs to change.
Can a hardware store copy a restricted key?
Normally not. Restricted keys are made on protected blanks, and copies go through an authorized channel, such as a key card or the registered owner's approval. That is the point of the system. Tell us how many keys you need up front so we can order them together.
What if I lose all the keys to a high security lock?
Call us at (213) 577-1366, any hour. We can usually open the door without damaging it, then work out replacement keys. Depending on the system, new keys may need to be ordered or authorized, and we will tell you what applies to your lock.
Is a high security lock worth it on an older bungalow door?
It can be, if the door and frame are in good condition. In older homes, heat cycles can shift wood and throw off deadbolt alignment, so we check that first. Sometimes the better move is correcting the door or reinforcing the strike, and we will tell you if so.
Do you install high security locks for commercial properties?
Yes. Shops, offices and warehouses often benefit from commercial security locks with restricted keys, sometimes inside a master-key plan. We look at the doors, the number of keyholders and how often the doors are used, then recommend a setup that fits.
Do you serve both Canoga Park ZIP codes?
Yes. We work throughout Canoga Park, including 91303 and 91304, and the surrounding area. Call (213) 577-1366 and tell us the address, and a mobile van comes to you from our Westwood base.
