A standard builder-grade deadbolt is built to a price, not to resist a determined person. In Sherman Oaks, where the homes along the valley floor and up into the Santa Monica Mountains carry real value, many owners decide the lock on the front door should match what is behind it. High security cylinders are the answer: they use tighter tolerances, hardened components and more complex key designs to resist picking, bumping, drilling and unauthorized key duplication.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and David Shar leads the work. We are a fully mobile operation with no storefront, so every job begins with a conversation about your door, your risks and how you actually use the property. We then bring the hardware and tools to you, whether that is a 1950s ranch home off Van Nuys Boulevard, a hillside estate, or a shop on Ventura Boulevard.

High security is more than a brand name on a cylinder. It is the cylinder, the strike plate, the door and frame, and the key control that goes with it. We look at the whole system so you are not paying for a premium lock mounted in a weak door. We work with restricted-keyway systems such as Medeco and Mul-T-Lock, along with electronic and smart deadbolts where they suit the situation.

How it works in Sherman Oaks

  1. 1

    Talk through your goals

    Call (323) 997-8867 any time. We ask what you want to protect, who currently holds keys, and whether this is a new purchase, a post-incident upgrade, or a business changeover. That tells us which cylinders and level of key control fit.

  2. 2

    Assess the door and hardware

    We come to you and inspect the door, frame, strike and existing locks. A strong cylinder in a thin frame or short strike screws is wasted money, so we flag reinforcement needs honestly before any work begins.

  3. 3

    Select the lock and keyway

    We recommend a pick-, bump- and drill-resistant cylinder suited to the door, and explain how restricted keyways limit unauthorized copying. For some properties an electronic or smart deadbolt makes more sense, and we say so.

  4. 4

    Install and fit precisely

    We fit the new cylinders or deadbolts, align the bolt and strike, and reinforce where needed. Doors in older Spanish and ranch homes often have settled over decades, so careful alignment matters for smooth operation.

  5. 5

    Cut and test keys

    We supply the keys, test every lock repeatedly from both sides, and make sure all doors you want keyed alike actually are. Gate keypads or access devices can be reprogrammed in the same visit when applicable.

  6. 6

    Walk through key control

    We explain how to order additional keys, who is authorized, and what to do if a key goes missing, so the security you paid for stays intact.

What affects the price

  • The lock system chosen: a restricted-keyway mechanical cylinder, an electronic deadbolt, and a full multi-door system each involve different hardware costs.
  • The number of doors and cylinders, and whether you want them keyed alike or separately.
  • Door and frame condition, including whether reinforcement, strike upgrades or minor repair is needed for the lock to perform.
  • Key control level and the number of keys you need cut, including any restricted or card-authorized key requirements.
  • Extra work such as gate keypad reprogramming, smart-lock setup, or commercial panic hardware checks.
  • Time and location of the call, since we are 24/7 and fully mobile and after-hours visits are scheduled differently from daytime ones.

Why Sherman Oaks chooses us

  • In business since 1987, with David Shar as owner and lead technician, so your project is not handed off to an unknown crew.
  • Fully mobile and available 24/7, so installs happen at your door on your schedule rather than at a shop counter.
  • We assess the door and frame first and tell you plainly if a premium cylinder will not help without reinforcement.
  • Experience across residential and commercial settings, from gated hillside estates to aluminum storefronts on Ventura Boulevard.
  • Comfortable with both mechanical high security systems and electronic or smart locks, so recommendations follow your needs rather than one product line.
  • Clear explanation of key control and how restricted keyways work, so you know what protection you are actually getting.

High Security Locks across Sherman Oaks

Sherman Oaks splits into two very different security pictures. South of the Boulevard, the hillsides climb into the Santa Monica Mountains toward the edge of Fryman Canyon, with gated estates, custom contemporary homes and canyon properties on winding roads. Owners there often want Medeco or Mul-T-Lock cylinders on the entry doors and a driveway gate keypad or call-box that is reprogrammed whenever staff, contractors or tenants change. Isolated lots and long driveways make door strength and key control especially worthwhile.

On the valley floor, the 1930s to 1950s Spanish, traditional and ranch homes in areas like Chandler Estates are often being bought, renovated or resold. A new owner in 91423 may want every old key made useless and a smart or high security deadbolt installed at the same time, with the door checked for settling and wear. Condos and apartments near the Galleria, in the 91403 area, bring their own needs, such as upgraded unit-door cylinders that fit building rules.

Along the Ventura Boulevard commercial corridor, near the Sherman Oaks Galleria and Westfield Fashion Square, restaurants and boutiques frequently run aluminum storefront doors with Adams Rite locks and panic hardware. After a manager leaves, rekeying those locks and checking the exit devices is a common and sensible call. With I-405, US-101, Sepulveda and Van Nuys Boulevard all close by, we reach homes and businesses across Sherman Oaks around the clock, and it all starts with a call to (323) 997-8867.

High Security Locks in Sherman Oaks — FAQs

What makes a lock high security?
High security cylinders use tighter manufacturing tolerances, hardened pins and inserts, and more complex key designs to resist picking, bumping and drilling. Many also use restricted keyways so keys cannot be casually copied at a hardware store.
Can you install Medeco or Mul-T-Lock in Sherman Oaks?
Yes. We install restricted-keyway systems such as Medeco and Mul-T-Lock at homes and businesses throughout Sherman Oaks. Call (323) 997-8867 and we will talk through which option suits your door.
Will a high security lock work on my older door?
Usually, but the door and frame matter. Older Spanish and ranch homes may need strike reinforcement or alignment work so the lock performs as intended. We check this during the assessment and tell you honestly what is needed.
Can you reprogram my driveway gate keypad at the same time?
In many cases yes. For hillside estates south of the Boulevard, we can often handle gate keypad reprogramming alongside cylinder upgrades. Describe your gate system when you call (323) 997-8867 so we can prepare.
I just bought a home in Chandler Estates. What should I do first?
Rekey or replace the locks so no previous keys work. This is a good moment to upgrade to a high security or smart deadbolt, since we can do the install and key setup in one visit.
Do you handle commercial locks on Ventura Boulevard?
Yes. We work on aluminum-storefront locks, including Adams Rite types, and can rekey and check panic hardware after staff changes. Call (323) 997-8867 any hour to arrange it.
Are smart locks as secure as mechanical high security locks?
They can be good choices, but they are different tools. Mechanical restricted-keyway cylinders excel at pick and drill resistance, while smart locks add convenience and access tracking. We help you choose based on how you use the door.
Do you have a shop I can visit?
No. We are fully mobile and come to you, 24/7, anywhere in Sherman Oaks. Call (323) 997-8867 to discuss your project.
