A standard builder-grade deadbolt is designed to keep honest people honest. A high security lock is built for a different job: it resists the methods that defeat ordinary cylinders, including lock picking, bumping, drilling and forced removal. Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and owner and lead tech David Shar and our team install these locks on homes and small offices throughout the San Fernando Valley, Mission Hills included.

In Mission Hills, the need often comes from the age of the housing. Many homes here are late-1940s through 1960s stucco ranch and minimal-traditional houses, with some Spanish-influenced and mid-century pockets. Original cylinders and older locksets on those doors have had decades of wear, and many have passed through several owners with no one sure how many keys exist. Upgrading to a high security cylinder with a restricted keyway gives you a fresh start and real control over who can copy your key.

We are mobile only. There is no storefront to visit, so we bring the hardware and tools to your door, look at what you have, and recommend what fits. Sometimes that is a high security deadbolt. Sometimes it is a new cylinder in a lockset you want to keep. We will tell you plainly when a more expensive upgrade will not add real protection for your situation.

How it works in Mission Hills

  1. 1

    Talk through your concerns

    Call (323) 997-8867 any time, day or night. We ask about the doors involved, what you have now, and what is driving the upgrade: a break-in, a move, staff turnover, or simply wanting better protection.

  2. 2

    Inspect the doors and hardware on site

    Because we are mobile, we come to the property and check the door, the frame, the strike plate and the existing lock. A strong cylinder is only as good as the door and frame around it, so we look at all of it.

  3. 3

    Choose the right lock and key control level

    We explain the options, including pick-, bump- and drill-resistant cylinders and restricted keyways where key duplication is controlled. We help you match the level of protection to the door, whether it is a front entry, a side door, or an office suite.

  4. 4

    Install and reinforce

    We fit the new high security hardware, adjust alignment so the bolt throws cleanly, and recommend reinforcement where it makes sense, such as a longer strike plate screws or a stronger strike. On older doors we work carefully to avoid unnecessary damage to the wood or finish.

  5. 5

    Test, cut keys and hand over

    We test the lock repeatedly with the door open and closed, confirm every key works, and explain how to order additional keys through the restricted system so you stay in control of copies.

What affects the price

  • The type and grade of lock chosen, since restricted-keyway and drill-resistant designs differ in construction and cost.
  • How many doors or cylinders are being upgraded, and whether you want them keyed alike.
  • The condition of the door and frame, including whether reinforcement or strike work is needed.
  • Whether the existing hardware is an older mortise lockset that needs a specialty cylinder or careful fitting.
  • Residential versus commercial needs, such as master-key layouts for an office.
  • The number of keys you want cut and any later key-control or additional key requests.

Why Mission Hills chooses us

  • We have operated since 1987, so older mid-century hardware is familiar territory rather than a surprise.
  • We are fully mobile and available 24/7, so an upgrade after a break-in does not have to wait for store hours.
  • We assess the door and frame, not only the cylinder, and say so when reinforcement matters more than a pricier lock.
  • We take care with older and historic-adjacent doors so upgrades are sympathetic and do not damage original woodwork.
  • We explain key control in plain language, including how restricted keys limit unauthorized copies.
  • We will tell you if a lesser upgrade fits your needs, rather than selling the most expensive option.

High Security Locks across Mission Hills

Mission Hills sits in the northeast San Fernando Valley around the Historic Mission district, home to Mission San Fernando Rey de Espana and the Andres Pico Adobe, documented as the second-oldest residence in Los Angeles. Streets in ZIP code 91345 near the Mission are lined with quiet stucco ranch homes, and many owners want stronger locks without changing the look of a door that suits the neighborhood. A high security deadbolt in a finish that matches existing hardware is usually an easy way to do that.

Dennis Park, a historic tract, and the streets off San Fernando Mission Boulevard and Brand Boulevard include older homes where original cylinders and sometimes mortise locksets are still in use. For a home with a failing mortise lockset, we look at repair or a sympathetic upgrade first so the vintage door stays intact. Resale is also common here: a buyer of a 1950s ranch house often wants every exterior cylinder keyed alike with a new high security deadbolt on the front door.

Along the Sepulveda Boulevard corridor and near Providence Holy Cross Medical Center, small medical and professional offices have different needs. After staff changes, an office may want a commercial rekey with high security cylinders and a simple master-key setup so that access is controlled. Whether you are near CA-118 or tucked away close to the San Fernando Mission Cemetery, we come to you, with no storefront visit required.

High Security Locks in Mission Hills — FAQs

What makes a lock high security?
A high security lock is built to resist picking, bumping and drilling, and usually uses a restricted keyway so keys cannot be casually duplicated. Call (323) 997-8867 and we can explain which features suit your door.
Do you offer high security locks in Mission Hills at night or on weekends?
Yes. Crenshaw Lock Company is a 24/7 mobile locksmith, so you can call (323) 997-8867 at any hour about a lock upgrade, including after a break-in.
Can you upgrade the older locks in my 1950s ranch home?
Usually, yes. Many mid-century homes in Mission Hills have aging cylinders or deadbolts that can be replaced with high security hardware. We check the door and frame first to make sure the whole setup is sound.
I live near the Andres Pico Adobe and have an original mortise lock. Do I have to replace it?
Not necessarily. We look at repairing the mortise lockset or fitting a better cylinder so the vintage door is not damaged. If a full upgrade is the better choice, we will explain why.
What is a restricted key and why does it matter?
A restricted key uses a keyway controlled by the manufacturer, so copies generally cannot be made at a typical hardware kiosk. This gives you more control over who has access to your property.
Can you rekey several doors to one key and add a high security deadbolt?
Yes. This is common with resale purchases. We can key exterior cylinders alike and install a new graded high security deadbolt on the main entry. Call (323) 997-8867 to discuss your doors.
Do you handle small offices near Providence Holy Cross Medical Center?
We do small commercial work, including rekeying after staff changes and basic master-key setups with high security cylinders. We assess the doors on site and recommend what fits.
Do I need to visit your shop?
No. We are mobile only and have no storefront. We bring the locks and tools to your property in Mission Hills.
