What counts as a high security lock?
A high security lock is a cylinder and bolt built to resist the usual ways locks get beaten: picking, bumping, drilling, and unauthorized key copying. A standard pin-tumbler cylinder from a hardware store relies on simple pins and a keyway that almost any key shop will cut for anyone who walks in. A high security cylinder changes those weak points. It uses security pins that fight a pick, tighter tolerances that make bump keys far less effective, hardened steel where a drill would attack, and often a restricted keyway so copies cannot be cut at a kiosk.
No lock is unbeatable, and we won't tell you otherwise. The honest claim is that these locks take more time, more skill and more noise to defeat, and that is usually what separates a failed attempt from a successful one. They also control who can make keys, which matters more day to day than most owners expect.
- Pick-resistant locks: security pins and closer tolerances that make manipulation slow and unreliable.
- Bump-resistant locks: internal designs that blunt the effect of a bump key.
- Drill-resistant construction: hardened inserts protecting the shear line.
- Restricted keys: key blanks and key control that stop casual duplication.
Why would a View Park–Windsor Hills homeowner want one?
Most people who call us about high security locks are not reacting to a break-in. They are reacting to a question about keys. Who still has one? How many copies exist? Did the last contractor, tenant, relative or house sitter make their own? On a standard lock you can never fully answer that. With a restricted-key system you can, because copies require authorization.
This is especially true in a community where homes change hands slowly and carry a long history. A house that has been in a family for decades may have keys scattered among relatives, past caretakers and neighbors. Upgrading the cylinder, not just the key cuts, turns an unknown number of keys into a known number.
Other reasons we hear: a front door facing a quiet curving street with little foot traffic, a side entrance that is out of sight from the road, or simply wanting the main entry to be harder to pick than the one next door. We'll talk through which of those applies to you before recommending hardware.
How does a high security lock installation work, step by step?
We keep the process plain and in a sensible order, because the cylinder is only one part of a secure door. Here is how a typical job goes.
- You call (213) 577-1366. We answer around the clock, so a daytime appointment and an after-hours question get the same attention. We ask what door it is, what lock is on it now, and what worries you.
- We look at the door and hardware, in person at your property. We check the door's condition, the latch and bolt, the strike plate, the frame, and whether the existing lock body can take a better cylinder or needs replacing entirely.
- We explain your options in plain terms: a high security cylinder in your existing hardware, a full new deadbolt, or a different approach if the door is the weak link. You get the trade-offs, including key control and what happens when you need extra keys.
- We install and fit the hardware properly: cylinder, bolt, strike and the screws that hold them. Short screws and a loose strike defeat expensive cylinders, so we check these every time.
- We test every key and the full operation of the door, then hand over keys and explain how to order more under the system you chose, so you aren't surprised later.

Call (213) 577-1366Pick-resistant, bump-resistant or drill-resistant: what are you actually buying?
Marketing language blurs these terms, so here is what each one means on the door.
Pick resistance comes from security pins, often spool or serrated shapes, that false-set under a pick and trick the person working the lock. Bump resistance comes from design details that stop a bump key's impact from lining up the pins the way it does on a basic cylinder. Drill resistance comes from hardened steel pieces placed where a drill bit would normally defeat the lock. Restricted keys sit on top of all three, because the best-built cylinder still loses if anyone can duplicate its key.
- Ask which resistances the cylinder has. Many products claim one and skip the others.
- Ask how keys are controlled: card, authorization, or only dealer-cut.
- Ask whether the lock body, strike and door are strong enough to match the cylinder.
- Ask what happens if you lose every key. A good system has a clear answer.
What about original mortise locks and period hardware in View Park?
View Park–Windsor Hills is a hillside community of 1920s–1940s Spanish Colonial Revival, Mediterranean and traditional homes, and the View Park historic district was listed on the National Register of Historic Places in 2016. Many homes here still carry original mortise locks, glass knobs and period hardware, and owners often prefer to repair rather than replace. We respect that.
High security does not have to mean ripping out a 1930s mortise lock. In many cases the answer is to keep the visible hardware and improve what does the securing: a better mortise cylinder behind the existing trim, a properly set strike, and a supplementary deadbolt placed where it does the least damage to the door's appearance. Whether that works depends on the lock body's condition, and we tell you straight when an old mechanism is worn past sensible repair.
If the mortise lock itself needs work first, that is a separate job, and our team can handle it as part of lock replacement or repair. We would rather save a good original lock than replace it, and we'll say so.
How does this look across View Park, Windsor Hills and nearby streets?
Our service area here covers ZIP codes 90043 and 90008, from View Park and Windsor Hills through the streets near Baldwin Hills, Baldwin Vista, Hyde Park and the Crenshaw District, which sit in the City of Los Angeles. The community is about 11 miles from our Westwood storefront, and our mobile vans carry the tools and common hardware for the work.
A few situations come up in these neighborhoods again and again. Rekeying at sale or inheritance in the View Park historic district is the most natural moment to upgrade, because you are already changing who holds keys. If you are doing that, a restricted-key cylinder is worth a look before you settle for a plain rekey. Terraced hillside lots also mean gates and side entrances that sit well away from the street, and those doors often get less attention than the front one even though they are just as reachable.
The climate is gentle. Hilltop breezes and marine-layer mornings off the coast, with only modest seasonal swelling in older wood doors, are not hard on cylinders. We still check that a swollen or sagging door isn't binding the bolt, because a bolt that drags will wear any lock early.

Call (213) 577-1366What affects the cost of high security lock installation?
We don't quote numbers on a web page, because honest pricing depends on the door in front of us. Here is what moves the cost, so you can judge any estimate you receive.
Hardware level is the biggest factor. A cylinder with full pick, bump and drill resistance and a restricted keyway costs more than one with a single feature. Key control is next: patent-protected or authorization-only systems cost more to set up and to extend with new keys than open systems. Then comes the scope. Dropping a better cylinder into a sound existing lock is usually the more economical route. Replacing a worn lock body, adding a new deadbolt, reinforcing a strike or repairing a damaged door adds labor and parts.
Other factors: how many doors you want keyed alike, how many keys you need, whether the work is scheduled or urgent, and what time of day you call. We give you the price before work starts, in plain terms, and we explain what you'd give up if you chose a lighter option.
Do you handle commercial security locks too?
Yes, and the principles are the same with more people involved. Around the Slauson Avenue and Overhill Drive commercial corner, a shop or office has a back door, a front door and often a handful of employees with keys. Commercial security locks add key control for staff turnover, heavier-duty hardware, and sometimes keyed-alike or hierarchical systems so an owner can open everything while a staff member opens only one door.
Those larger systems are really commercial locksmith projects, and we'll scope them that way. If you only want one door upgraded, we can do that without selling you a whole system.
Why call Wilshire Lock & Key for high security locks?

Call (213) 577-1366What should you do before you call?
A few minutes of preparation makes the visit faster and the advice better. Look at the door and note the current lock brand if you can see one. Count how many keys exist and who has them. Think about whether you want smart features: if so, tell us up front, because smart lock installation and a restricted mechanical key can work together, but the choices affect each other. And if you plan to hand out spare keys, ask how key duplication works under the system we select, so a restricted key doesn't become an inconvenience.
When you're ready, call (213) 577-1366. A person answers, any hour, any day.
Frequently asked questions
Are high security locks really pick-proof?
No lock is pick-proof. High security locks are pick-resistant, meaning security pins and tight tolerances make picking much slower and less reliable. The lasting advantage is usually key control, since restricted keys can't be copied freely.
Can I add a high security lock to my original mortise lock in View Park?
Often yes. Many mortise lock bodies accept a better cylinder, so the visible hardware and glass knobs can stay. It depends on the lock's condition and fit, which we check in person before recommending anything.
What is a restricted key, and why does it matter?
A restricted key uses a protected blank and keyway, so a copy can only be made with authorization from the owner. It matters because lost, loaned or inherited keys can't be duplicated at a random kiosk.
Will a bump-resistant lock stop a bump key?
Bump-resistant cylinders are designed so a bump key doesn't reliably set the pins. They greatly reduce that risk, though the door, strike and frame still need to be solid to complement the lock.
Is a high security lock worth it if my door is old or warped?
The cylinder only helps if the door supports it. We check the bolt, strike, frame and door condition first. Sometimes a repair or reinforcement comes before, or alongside, the new lock.
Can you rekey to a high security cylinder when I buy or inherit a house?
Yes. Sale or inheritance is a natural time to do it, because you are already changing who holds keys. We can rekey the existing locks or fit restricted-key cylinders, depending on what you want.
Do you install commercial security locks near Slauson and Overhill?
Yes. We handle single-door upgrades and larger keyed systems for shops and offices, including key control for staff changes. Larger systems are scoped as commercial locksmith projects.
How much does a high security lock cost?
It depends on the hardware level, the key control system, how much of the existing lock and door can be reused, and how many keys you need. We explain these factors and give you a price before work begins.
Do you answer calls at night or on weekends?
Yes. Our phone at (213) 577-1366 is answered 24 hours a day, 7 days a week, year-round, by our own company rather than an outside dispatch service.
Should I ask for a license before hiring a locksmith?
Yes. California requires locksmith companies to hold a BSIS LCO license, and any locksmith should be willing to provide the number on request. It's a reasonable question for any company, including ours.
