Most homes in Santa Clarita were built as part of master-planned tracts between the 1970s and the 2000s, and the exterior locks on many of them are still the builder-grade Kwikset or Schlage cylinders that went in on day one. They work fine for everyday use, but they are not designed to resist skilled picking, bumping or drilling, and the same key pattern may have been copied by previous owners, tenants, contractors and neighbors over the years. A high security lock addresses both problems: a harder physical cylinder and a key you actually control.

High security hardware differs from a standard cylinder in a few ways. Hardened steel inserts help resist drilling, tighter tolerances and additional security pins make picking and bumping far more difficult, and many systems use restricted keyways so that duplicates can only be cut with authorization. Some systems add a card or registration process, which matters if you want to know that nobody can quietly make a copy at a hardware store kiosk.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987 under owner and lead technician David Shar. We are mobile only, with no storefront, so every job begins with a conversation about what you are protecting and ends with hardware installed and tested at your door. Whether you have a two-story tract home in Saugus, a townhome in Valencia or a commercial space needing better exit-device and cylinder protection, we can match the lock to the situation instead of selling you more than you need.

How it works in Santa Clarita

  1. 1

    Talk through your situation

    Call (323) 997-8867 any time. We ask about the doors involved, what you have now, whether you have had break-in concerns, and whether you want one key for everything. This helps us recommend the right level of hardware before we arrive.

  2. 2

    Assess the doors and existing hardware

    On site, we look at the cylinders, deadbolts, strike plates, door thickness and frame condition. A strong cylinder is of limited value if the door frame or strike is weak, so we point out anything that undermines the upgrade.

  3. 3

    Choose the lock and key system

    We explain your options for pick-, bump- and drill-resistant cylinders and for restricted keyways. You decide how many keys you need, whether you want all exterior doors keyed alike, and whether any doors need separate access, such as a detached garage or rental unit.

  4. 4

    Install and fit the hardware

    We remove the old cylinders or deadbolts and install the new high security hardware, making sure the bolt throws smoothly and the door latches correctly. Where needed, we reinforce the strike plate or adjust alignment.

  5. 5

    Test, cut keys and hand over

    We test every lock repeatedly with the final keys, confirm the keys work smoothly, and explain how to request additional copies under the restricted system. You leave knowing exactly what was installed and how to maintain it.

What affects the price

  • The brand and security level of the cylinder or deadbolt, since restricted and drill-resistant systems vary widely in construction.
  • The number of doors and cylinders being upgraded, including garage entry doors, side doors and any gates.
  • Whether the doors need keyed-alike setups or master-key arrangements across several locks.
  • The condition of the door, frame and strike plate, and whether reinforcement or alignment work is needed.
  • Whether the work is residential or commercial, including exit devices and panic hardware.
  • Timing of the visit, such as an after-hours or overnight call compared with a scheduled appointment.

Why Santa Clarita chooses us

  • Fully mobile service: we bring the hardware and tools to your door rather than asking you to visit a shop, because we have no storefront.
  • In business since 1987, with owner and lead technician David Shar overseeing the work.
  • We assess the door and frame, not just the lock, so you do not pay for strong hardware that a weak strike plate undermines.
  • Honest recommendations: if a quality standard cylinder meets your needs, we will say so rather than push the most expensive option.
  • Available 24/7, which matters when a break-in, a lost key or a tenant turnover forces an urgent upgrade.
  • We handle both homes and businesses, from tract-home deadbolts to commercial cylinders and exit devices.

High Security Locks across Santa Clarita

Santa Clarita is a patchwork of neighborhoods with very different lock needs. In Saugus and Plum Canyon, many two-story single-family homes in HOA tracts still have the original builder-grade cylinders, and new buyers often want a high security upgrade along with a rekey so every exterior door shares one key they control. In Valencia, near Westfield Valencia Town Center and along Valencia Blvd and Newhall Ranch Rd, townhomes, condos and newer developments often call for lock upgrades that respect HOA rules and shared-entry layouts.

Older parts of town have their own character. Around Newhall and Old Town Newhall, you will find a mix of older homes and small commercial spaces where stronger cylinders and better door reinforcement can make a real difference. In Canyon Country, along Soledad Canyon Rd, we also see gated communities where pedestrian gates and keypad or fob systems sit alongside the front-door hardware, so a good security plan covers every point of entry. In ZIP codes such as 91350, 91351 and 91355, we regularly help owners who want better control over who holds a working key.

Because we are mobile, we reach homes and businesses off I-5, CA-14 (Antelope Valley Fwy), Sierra Highway and Bouquet Canyon Rd without anyone needing to travel to us. For residents near College of the Canyons, William S. Hart Park or the Valencia industrial areas, the process is the same: call (323) 997-8867, tell us about your doors, and we will come to you.

High Security Locks in Santa Clarita — FAQs

What makes a lock high security instead of standard?
High security locks use hardened components to resist drilling, tighter tolerances and extra security pins to resist picking and bumping, and often a restricted keyway that limits unauthorized key copying. Call (323) 997-8867 to discuss which features fit your doors.
Are the builder-grade locks on my Santa Clarita tract home a problem?
They are fine for basic use, but they are not built to resist skilled attacks, and the key pattern may have been copied by earlier owners or contractors. Upgrading or at least rekeying is a sensible step after buying a home.
Can you upgrade all my exterior doors to one key?
Yes. We can install high security cylinders on the front door, garage entry, and side or back doors, all keyed alike so you carry one key. Many new buyers in Saugus and Valencia choose this.
Do you offer restricted keys that cannot be copied easily?
Yes, restricted keyway systems are one of our options. Copies are controlled through the system rather than any hardware store key machine. We explain how duplicates are requested before you decide.
Will a high security lock work with my HOA rules?
Many HOAs care mainly about exterior appearance and finish. We can often match the look of existing hardware, but check your HOA guidelines, and we can discuss options that fit them.
Do you work on commercial doors and exit devices?
Yes. We service commercial cylinders and exit devices, including panic-bar repair, for businesses in areas such as Valencia. Call (323) 997-8867 to describe the door and the problem.
Is a stronger lock enough if my door frame is weak?
Not always. A strong cylinder can still be defeated if the strike plate, frame or door is weak, so we inspect those parts and recommend reinforcement when needed.
Do I need to come to a shop to choose a lock?
No. We are fully mobile and have no storefront. We come to your home or business in Santa Clarita, any hour, and walk through the options on site.
