Porter Ranch sits on the northwest rim of the San Fernando Valley, and much of it was built in the 1980s through the 2000s and later. The homes are handsome and well kept, but the hardware on the doors is often still builder-grade: a standard pin-tumbler cylinder that can be picked, bumped or drilled by someone with the right tools and a little patience. For a home with a large entry, a hillside lot or a quiet cul-de-sac, that is a gap worth closing.

High security locks address it at the cylinder. Instead of a basic five- or six-pin design, they use tighter tolerances, hardened inserts, security pins, sidebars or other additional mechanisms that resist picking, bumping and drilling. Many also use restricted key blanks, so a copy can't be cut at any random kiosk. That gives you real control over who holds a working key, which matters for families, rental properties, home offices and HOA amenity buildings alike.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, led by owner and lead technician David Shar. We are mobile only, with no storefront to visit. We assess your doors at your property, explain the options plainly, and install the hardware on site, whether that is one front door or a full set of exterior entries.

How it works in Porter Ranch

  1. 1

    Call and describe your doors

    Phone (323) 997-8867 and tell us what you have: the number of exterior doors, whether they are wood, steel or glass-paneled, and any smart locks or gate systems already in place. This helps us arrive with the right cylinders and hardware.

  2. 2

    On-site security assessment

    We look at the cylinders, deadbolts, strike plates, door frames and how the doors are hung. A high security cylinder only helps if the door, frame and strike are sound, so we point out weak spots such as short screws or thin strikes.

  3. 3

    Choose the level of protection

    We go over high security cylinder options, restricted keyway systems, and how they fit with your existing deadbolts or smart locks. You decide how much protection suits the property and how many keys you want controlled.

  4. 4

    Installation and reinforcement

    We install the new cylinders or deadbolts and, where needed, reinforce strike plates and frames. If you want several doors on one key, we set the system up that way during the visit.

  5. 5

    Testing and key handover

    We test every lock repeatedly from both sides, confirm smooth operation, and hand over your keys along with any key-control or authorization card that applies, plus guidance on ordering extra keys safely.

What affects the price

  • The lock grade and brand chosen, since cylinders with more drill-resistant and pick-resistant features differ in cost from standard hardware.
  • The number of doors and cylinders being converted, and whether you want them all keyed alike.
  • Whether a restricted keyway with controlled key duplication is part of the system.
  • Door and frame condition, including any strike plate or frame reinforcement the doors need.
  • Compatibility with existing smart locks, deadbolts, or gate and intercom hardware.
  • Whether the visit is scheduled in advance or requested after hours.

Why Porter Ranch chooses us

  • Fully mobile service: we do the assessment and installation at your door, so there is no shop trip and no leaving a property unsecured.
  • Active since 1987, which means decades of seeing how locks fail in real homes and how to prevent it.
  • We look at the whole door, not just the cylinder, because a strong lock in a weak frame is a false sense of security.
  • We explain restricted keys honestly, including their limits, so you know exactly what protection you are buying.
  • We are comfortable working alongside smart locks and gate systems, which are common in Porter Ranch's newer developments.
  • Available 24/7, so a break-in or lost-key scare at night can still be dealt with promptly.

High Security Locks across Porter Ranch

Porter Ranch homes range from tract houses in the Renaissance and Sorrento areas to larger properties in Porter Ranch Estates and the gated Oaks of Porter Ranch. Many were fitted with builder-grade hardware, and the gated setting can encourage a relaxed attitude toward the front door. Upgrading to high security cylinders is a sensible layer behind the gate, especially at side doors, garage entries and rear slider-adjacent doors that are out of view from the street.

In the 91326 and 91327 ZIP codes, we also see the effects of the environment. Homes near the foothills and along roads such as Sesnon Blvd and Porter Ranch Dr deal with wind-driven dust and grit that can foul cylinders over time. A well-made high security cylinder, installed properly and lubricated correctly, tends to hold up better than a worn builder-grade one, and we can replace seized cylinders while we are there.

We serve the area around The Vineyards at Porter Ranch and the Town Center, out toward Tampa Ave, Corbin Ave, Reseda Blvd and the Ronald Reagan Fwy. HOAs and club-style amenities, including clubhouses, pool buildings and storage rooms, often benefit from restricted keying so a management change does not leave old keys in circulation. We work on appointment or on an urgent basis, and we always travel to you.

High Security Locks in Porter Ranch — FAQs

What makes a lock high security?
A high security lock resists common attack methods such as picking, bumping and drilling. It typically uses tighter tolerances, security pins or sidebars, and hardened components. Many also use restricted keys that are harder to copy.
Do you install high security locks in the gated Oaks of Porter Ranch?
Yes. We are mobile and serve gated communities, subject to getting through your gate or intercom. Call (323) 997-8867 to arrange access, and we can also discuss how the locks interact with your gate and smart-lock setup.
Can high security locks work with my smart lock?
Often yes, depending on the model. Some smart locks keep a standard keyed cylinder that can be upgraded, and others are separate devices. We check what you have on site and tell you plainly what is compatible.
Will a high security lock stop every break-in?
No lock is unbeatable. High security locks make picking, bumping and drilling much harder, but doors, frames and windows matter too. That is why we check the strike plate and frame as part of the job.
Can I get extra keys copied anywhere?
With restricted keyways, no. Duplicates are generally only available through authorized channels, which protects you from unwanted copies. We explain how to order more when we hand over your keys.
Can you rekey an HOA clubhouse or pool building to a restricted system?
Yes. After a management change, many Porter Ranch HOAs rekey amenity and common-area locks. We can set up a restricted system so keys are tracked. Call (323) 997-8867 to discuss the buildings involved.
My exterior lock is sticking from dust and grit. Do I need a new one?
Not always. Sometimes cleaning and proper lubrication restores it. If the cylinder is worn or seized, replacement is the better option, and that is a good moment to upgrade to a high security cylinder.
Do you have a shop I can visit?
No. We are fully mobile and come to your home or property in Porter Ranch, 24/7. Call (323) 997-8867 to get started.
