What makes a lock high security, and what doesn't?
The phrase gets used loosely. On a hardware-store package it can simply mean a heavier deadbolt. In locksmith work it means something narrower: a cylinder built to resist the usual ways locks get beaten, paired with a key that can't be copied on a whim. When we talk about high security locks in Van Nuys, we mean a combination of the features below, not one magic part.
Here's the honest part. No lock is pick-proof, and a high security cylinder won't help if the door around it is weak. These locks raise the effort, time, and noise needed to get through, and they give you real control over who holds a working key. That control is often the bigger benefit.
- Pick resistance: tighter machining tolerances and security pins (spool and serrated pins, plus extra locking elements in some designs) that make picking slow and demanding, even for someone with training.
- Bump resistance: internal designs that don't respond to a bump key the way a basic builder-grade pin-tumbler cylinder does. If your current lock is a standard cylinder, bump-resistant locks are the upgrade to ask about.
- Drill resistance: hardened steel inserts in the cylinder that wear down drill bits.
- Restricted keys: key blanks and keyways controlled by the manufacturer. Ordinary key duplication at a kiosk won't work on these, which is the point; copies generally need authorization.
- Solid hardware around the cylinder: a hardened steel bolt, a reinforced strike plate, and long screws that reach the framing.
When does it make sense to upgrade to high security locks?
Most of our high security lock installation and replacement calls start with a situation rather than a shopping list. These come up again and again:
Sometimes the lighter-cost move is a different one. If your lock is sound and your only worry is a key that's out there somewhere, rekeying the lock to a new key cut may solve it. We'll tell you plainly which route fits, even when it's the smaller job.
- You can't account for every key. A former tenant, roommate, contractor, or employee may still have a copy, and a standard key can be duplicated almost anywhere.
- You hand out keys regularly and want some control over who can make copies, instead of guesswork.
- There was a break-in or an attempted entry. If someone worked on the cylinder, the lock deserves replacing, not just a look.
- You run a business and want commercial security locks on a back door, supply room, or office suite, with keys staff can't casually copy.
- You want home security locks on the front door that match the effort you've already put into the rest of the house.

Call (213) 577-1366How do we install or replace high security locks?
A good installation is mostly patience at the door. This is how we run it, whether it's one front door or a row of commercial entries.
David oversees how the work is done at Wilshire Lock & Key, and the person at your door works for our company, not for a broker who forwarded your call.
- You call (213) 577-1366 and tell us what you're protecting: how many doors, what type of door, and who needs keys. If you're actually locked out, say so and we'll handle that first.
- We look at the door, frame, and existing hardware before recommending anything. A lock that doesn't suit the door's thickness or the frame's condition will disappoint you later.
- We explain the options in plain terms: which cylinder system, how restricted the keys are, and what each choice does and doesn't protect against.
- We install or replace the cylinders and deadbolts, align the bolt and strike so it throws freely, and reinforce the strike and screws where the frame needs it.
- We cut and test the keys, then work the lock from both sides and check that it operates smoothly with the door open, closing, and fully latched.
- We hand over the keys along with the key-control details: how the restricted system works, who can authorize copies, and what paperwork or cards to keep safe if your system uses them.
Does the door matter as much as the lock?
Nearly. A pick-resistant deadbolt in a cracked or thin frame is a good lock in a bad position. When doors are forced, it's usually the frame or strike that gives way, not the cylinder.
That's why we check the strike plate, screws, and jamb on every high security lock replacement. A reinforced strike with long screws anchored into the framing can add more real-world resistance than a pricier cylinder would alone. If you're adding a new bolt instead of swapping a cylinder, our deadbolt installation service covers boring the door and setting the hardware correctly.
We'll also tell you when the door is the weak point and a lock upgrade won't fix it. Sometimes the honest advice is to deal with the frame or the door first, and put the better cylinder in afterward.
What affects the cost of high security lock installation?
We don't print numbers on a web page, because the price depends on facts we can only see at the door. Here's what moves it:
We give you the figure before work starts, after we've seen what you have. If a lighter-cost option does the job, it's usually the more economical route, and we'll say so.
- The lock system. Pick-resistant and bump-resistant cylinders vary widely in design, and a restricted-key system with controlled blanks costs more than a basic upgrade.
- How many doors and cylinders. One front door is a different job than a building with several entries, and keying them together takes planning.
- New installation versus replacement. Swapping a cylinder in a sound deadbolt is lighter work than preparing a door for new hardware.
- Door and frame condition. Reinforcement, a repaired jamb, or a misaligned door adds time and parts.
- Key quantity and authorization. More keys, and stricter control over who can order copies, change the total.
- Timing. A planned daytime visit is simpler to schedule than an urgent night call.

What do high security locks look like in Van Nuys?
Van Nuys covers ZIP codes 91401, 91405, 91406, and 91411, and what people need from a lock changes block by block.
Across the flats, postwar 1940s and 50s bungalows and ranch-style homes are common. So are 1960s to 80s garden apartments and dingbat-style multifamily buildings along corridors like Sepulveda, Kester, and Victory. Many older apartment buildings still have their original knob-and-deadbolt hardware, which was built for an era of basic cylinders and common keyways. For a homeowner in a bungalow tract, replacing the front-door deadbolt with a pick-resistant, bump-resistant one is a sensible first step. Security screen doors, a common sight on denser blocks near the civic center, add a layer, but they don't replace a solid lock behind them.
Van Nuys also has a high renter share, which makes key control a practical issue. In Kester-area garden apartments, rekeying after tenant turnover is routine work. Restricted-key cylinders change that routine: because copies need authorization, an owner has a better idea how many working keys exist. If you manage units, our page for a locksmith for landlords covers turnover work, and high security cylinders are one way to tighten what happens between tenants.
Along the Van Nuys Boulevard corridor, small storefronts often rely on one deadbolt and a handful of keys copied over the years. Around the Van Nuys Civic Center government complex, offices tend to need keying that has structure, meaning who can open what. A restricted-key cylinder combined with a master key system can provide that. If you operate a unit in the Raymer Street industrial district near Van Nuys Airport, personnel doors and storage rooms are where we'd start the conversation about commercial security locks. For broader business work, see our commercial locksmith page.
Heat matters too. Interior San Fernando Valley summers run well above Westside temperatures, and heat can swell wood doors and frames until latches bind. A tight-tolerance high security deadbolt is less forgiving of a door that's rubbing, so we check alignment and adjust the strike when needed so the bolt throws freely in July as well as January. On the plus side, corrosion risk is low this far from the coast, so finishes and internal parts don't face the wear that coastal salt air causes.

Call (213) 577-1366What should you ask any locksmith before installing high security locks?
California requires locksmith companies to hold a BSIS LCO license, issued by the Bureau of Security and Investigative Services. Ask any locksmith company for its license number before work starts and verify it with BSIS. It takes a minute and tells you a lot.
A few more questions are worth asking, from us or anyone else:
If you'd like to talk it through before deciding, contact us or call (213) 577-1366 any hour.
- Are the keys actually restricted, and who can authorize copies?
- Will you check the door, frame, and strike, or just swap the cylinder?
- Will I get the price before work begins, and does it include the keys?
- Does the hardware carry a recognized grade rating, such as an ANSI/BHMA grade?
- Will your own company do the work, or is it subcontracted?
Frequently asked questions
What's the difference between pick-resistant and bump-resistant locks?
They defend against different techniques. Pick-resistant locks use tight tolerances and security pins to make manipulation with picks difficult. Bump-resistant locks use internal designs that don't respond to a bump key. Good high security cylinders usually combine both, plus drill resistance, so you aren't choosing one protection over another.
Can a restricted high security key be copied?
Generally not at a kiosk or hardware store. Restricted keyways are controlled by the manufacturer, so copies typically need authorization, and the exact process depends on the system installed. We explain how yours works when we hand over the keys, so you know who can order extras and what to keep safe.
Can I install high security locks in a rental apartment?
Check your lease first, since many require landlord permission to change locks. If you're a tenant, ask the owner or manager before work starts. If you own or manage the building, high security cylinders can help with key control between tenants, and we're happy to walk through the options.
Will a high security lock fit my existing door?
Often, yes, but we confirm at the door. Door thickness, the existing bore, and frame condition all matter. Older doors may need adjustment or reinforcement for the new hardware to work well. Describe what you have when you call, and we'll tell you whether it's a simple replacement or a bigger job.
Do high security locks make a door burglar-proof?
No, and anyone who says otherwise is overselling. They make the lock itself much harder to defeat quietly and control who holds keys. But doors are also forced at the frame, strike, or hinges, so we check those during installation. Think of the lock as one strong layer, not the whole defense.
What if I lose a restricted key?
Call us. Depending on the system, we may be able to produce a replacement through the authorization process, or we may recommend rekeying or replacing the cylinder so the lost key no longer works. If you can't be sure where the key ended up, changing the cylinder is the safer choice.
Can you install high security locks at night or on weekends?
Our phone line is answered 24 hours a day, 7 days a week, year-round at (213) 577-1366. If you have an urgent security problem, such as a damaged lock after a break-in, call anytime and we'll tell you what we can do. Planned upgrades are simpler to schedule during the day.
Do you serve all parts of Van Nuys?
Yes. We cover Van Nuys, including ZIP codes 91401, 91405, 91406, and 91411, with mobile vans dispatched from our Westwood storefront at 10740 Wilshire Blvd. Whether you're near the civic center, along Sepulveda or Victory, or in the industrial blocks by the airport, call and we'll come to you.
