A standard builder-grade deadbolt is designed to be affordable and quick to install, not to hold up against someone who knows what they are doing. High security locks are a different category. They use tighter tolerances, hardened steel components, anti-pick and anti-bump pin designs, and drill-resistant inserts that protect the cylinder itself. Many also use restricted key blanks, so a copy cannot simply be cut at any hardware counter.

In Valencia, a lot of the housing was built to a consistent standard as part of the master-planned community that Newhall Land began developing in 1965. That means many tract homes, townhomes and condos share similar entry hardware, and plenty of it is still the original builder-grade type or a basic retail replacement. For homeowners who want a real step up, upgrading the front door, garage entry and rear slider-adjacent doors to high security cylinders is one of the most practical improvements available.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, led by owner and lead tech David Shar. We are fully mobile, with no storefront to visit, so everything happens at your door. We assess what you have, explain your options plainly, and install hardware that fits your door, your HOA rules and the way you actually live or work.

How it works in Valencia

  1. 1

    Call and describe your doors

    Reach us at (323) 997-8867 any hour. Tell us whether this is a home, townhome, condo or business space, how many doors are involved, and what prompted the upgrade, such as a recent move, a break-in attempt or a lost key.

  2. 2

    On-site assessment

    We come to you and look at each door, frame, strike plate and existing lock. A high security cylinder only helps if the door and frame can support it, so we check for thin jambs, short screws and loose strikes before recommending hardware.

  3. 3

    Choose the security level and key control

    We walk through options for pick, bump and drill resistance, and explain restricted keyways, where duplicates are limited to authorized sources. You decide how much key control suits your household, property manager or tenant situation.

  4. 4

    Installation and reinforcement

    We install the new cylinders or deadbolts and reinforce the weak points we found, such as strike plates and frame anchoring. Where it makes sense, we match several doors to a single key so you are not carrying a ring of different ones.

  5. 5

    Testing and key handoff

    Every lock is operated repeatedly with the door open and closed to confirm smooth throw and proper alignment. We hand over your keys, explain how to order additional copies, and note any HOA or gate considerations.

What affects the price

  • The number of doors or cylinders being upgraded, since a single front door is a very different job from a whole home or office suite.
  • The security grade and brand of the hardware, including whether it uses a restricted keyway with controlled key duplication.
  • Whether the existing door and frame need reinforcement, such as a heavier strike plate or longer anchoring screws, to support the new lock.
  • Whether you want everything keyed alike or a master-key structure, which is common for business tenants and property managers.
  • The type of door and hardware, such as a standard deadbolt, a multipoint setup or commercial-grade hardware, which affects parts and labor.
  • The time of day you need service, since we work around the clock and after-hours calls can differ from scheduled daytime work.

Why Valencia chooses us

  • We are fully mobile and available 24/7, so upgrades and urgent security fixes happen at your property rather than at a shop.
  • In business since 1987, with owner and lead tech David Shar overseeing the work and standards.
  • We inspect the door and frame first, because a strong cylinder in a weak door only gives a false sense of security.
  • We explain restricted key systems honestly, including what they protect against and what they do not, so you buy what you need.
  • We are familiar with HOA and gated-community considerations common in Valencia and can coordinate work with that in mind.
  • We handle both residential upgrades and commercial needs like master-key setups for business park tenants.

High Security Locks across Valencia

Valencia's village layout, linked by the paseo system, means homes in Westridge, Northbridge, Valencia Summit, Bridgeport and Old Orchard often look and feel similar from the street, and many share the same original builder hardware. Residents in ZIP codes 91354 and 91355 call us to replace those cylinders with pick-, bump- and drill-resistant versions, often right after buying a home, when it is unclear how many copies of the old keys are still out there.

Gated communities such as Westridge and Tesoro del Valle add another wrinkle. A new owner may want a full rekey and a high security upgrade coordinated with the HOA gate system, so entry hardware at the house and access at the gate work together. Townhomes and condos in paseo-connected villages off McBean Parkway have their own considerations, including shared-wall doors and association rules about exterior hardware, which we discuss before work begins.

On the commercial side, the Valencia Industrial Center and Commerce Center business parks are home to tenants who need master-key setups, commercial panic bars and higher-grade locks on storage and server rooms. Whether you are near Valencia Blvd, Magic Mountain Pkwy, Newhall Ranch Rd or just off the I-5, we bring the work to you. We also support staff and families around Henry Mayo Newhall Hospital, CalArts and Westfield Valencia Town Center who want better protection on their doors.

High Security Locks in Valencia — FAQs

What makes a lock "high security"?
High security locks use tighter tolerances, hardened components and special pin designs to resist picking, bumping and drilling. Many also use restricted keys that are harder to copy. Call (323) 997-8867 and we can explain which features fit your doors.
Can you install high security locks at my Valencia townhome or condo?
Usually yes, though HOA rules may affect exterior hardware, so check your association's guidelines first. We can look at your door, frame and any restrictions, then recommend hardware that fits. Reach us at (323) 997-8867.
Will a high security lock work with my gated community's system?
The lock on your door is separate from the community gate, but we often coordinate a rekey or upgrade alongside gate access in places like Westridge and Tesoro del Valle. We will talk through it with you before starting.
Do I need to replace my door to get a high security lock?
Not always. Many solid doors can take a high security cylinder or deadbolt as long as the frame and strike are sound. We check during the visit and reinforce weak points where needed.
What is a restricted key and do I need one?
A restricted key uses a keyway where blanks are controlled, so copies generally require authorization. It is useful for rentals, shared properties and anyone who wants tighter control over who holds a key. It is optional, and we will help you decide.
Can you set up a master-key system for a business in the Valencia Industrial Center?
Yes. We handle master-key structures and higher-grade commercial hardware for business tenants. Call (323) 997-8867 with how many doors and users are involved and we can plan the layout.
Are you available outside normal business hours?
Yes, we are a 24/7 mobile locksmith. If a break-in or lost key leaves you needing better locks right away, call (323) 997-8867 at any hour.
Do I have to visit a shop to pick out my locks?
No. We are fully mobile with no storefront, so we bring options to your Valencia home or business, install them on-site and test everything before we leave.
