Most of Lakewood was built in a few short years in the early 1950s, and a great many of those single-story stucco ranch homes still run the original builder-grade Kwikset hardware. Those locks did their job for decades, but they were never designed to resist the way modern break-ins and key abuse actually happen. A high security lock is a different class of hardware: tighter tolerances, hardened components, and key systems that are harder to copy or manipulate.

When we talk about high security, we mean three things in particular. Pick resistance, which makes it far more difficult to manipulate the pins by hand. Bump resistance, which defeats the common trick of rapping a filed key to jump the pins. And drill resistance, which uses hardened inserts that protect the cylinder's vital parts from being drilled out. Many systems also use restricted keyways, so a key cannot simply be duplicated at any hardware kiosk.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, led by owner and lead technician David Shar. We have no storefront. Everything happens at your door, which means we can look at the actual door, frame, and strike plate before recommending anything. Whether you own a ranch house near Rynerson Park or run a shop in the Lakewood Center area, we will match the hardware to the real risk instead of selling the most expensive option by default.

How it works in Lakewood

  1. 1

    Talk through your concerns

    Call (323) 997-8867 and tell us what is driving the upgrade: a recent break-in attempt, a move, a tenant change, or simply worn-out original locks. We will explain what we can do and arrange a visit at a time that works, day or night.

  2. 2

    Inspect the door, frame, and strike

    A strong cylinder in a weak door does little good. On site we check the door thickness, the condition of the jamb, the strike plate, and how the existing deadbolt sits. On older Lakewood ranch homes, seized or misaligned deadbolts are common, and we note anything that needs correcting.

  3. 3

    Choose the right level of protection

    We go over the options: high-security deadbolts, restricted keyways, and keying choices. You decide how many keys you need and whether the locks should be keyed alike across your doors or kept separate.

  4. 4

    Install and reinforce

    We remove the old hardware and fit the new high-security locks, adjusting the bore, latch, and strike so everything operates smoothly. Where the frame is weak, we discuss reinforcement such as a heavier strike plate with longer screws.

  5. 5

    Test and hand over keys

    We test every lock repeatedly with the door open and closed, then hand over your keys and any key authorization or card details that apply to your system. We explain how to order additional keys the correct way.

What affects the price

  • The type of high-security system chosen, since restricted keyways and patented key control cost more than standard hardened deadbolts.
  • How many doors and cylinders are being replaced, and whether they will be keyed alike or separately.
  • The condition of the existing door and frame, including any seized deadbolts, worn bores, or strike plates that need replacing or reinforcing.
  • Whether the job is residential or commercial, including storefront doors, glass doors, or master-key arrangements for several staff.
  • How many keys and any additional key cards or authorizations you want at handover.
  • The time of day or night you need service, given that we are available 24/7.

Why Lakewood chooses us

  • Fully mobile service: we do the work at your door, so we assess the actual door and frame rather than guessing from a description.
  • Experience since 1987 with older housing stock, including the original builder-grade hardware found across Lakewood's early-1950s tract homes.
  • Honest recommendations: if a good rekey or a modest deadbolt upgrade fits your situation, we will say so rather than push top-tier hardware.
  • Door-first thinking: we look at the jamb, strike, and latch alignment, because a high-security cylinder is only as strong as what it is mounted in.
  • One company for residential and commercial work, from a single ranch home to a retail setup with multiple staff keys.
  • Available 24/7, so an urgent upgrade after a scare does not have to wait for business hours.

High Security Locks across Lakewood

Lakewood's neighborhoods share a remarkably uniform look. In Lakewood Park, Lakewood Village, and Carson Park, rows of similar single-story stucco ranch houses were built around 1950 to 1953, and many still carry their original Kwikset locksets. That sameness cuts both ways: a lock that is easy to understand is also a lock that burglars know well. Upgrading the front and back doors to pick-, bump- and drill-resistant hardware is a practical step, especially after buying a home, when you cannot know who holds old keys.

We also see the age of these homes in the hardware itself. A mid-century deadbolt in a Carson Park ranch can seize in the jamb after decades of use, and replacing it with a modern high-security deadbolt solves both the lockout risk and the security gap at once. For homes in ZIP codes like 90712 and 90713, we often pair a new cylinder with a sturdier strike plate, since the original wood frames are rarely reinforced.

On the commercial side, the retail and office area around Lakewood Center and The Centre at Sycamore Plaza has tenants who change staff regularly. Restricted keys give a business more control over who can duplicate access. We travel along Lakewood Blvd, Del Amo Blvd, Carson St, the SR-91, and the I-605 to reach customers across Lakewood, including 90715 and 90711, near parks such as Rynerson Park and Mayfair Park. Call (323) 997-8867 any time.

High Security Locks in Lakewood — FAQs

What makes a lock high security rather than standard?
High-security locks use tighter tolerances, hardened parts, and designs that resist picking, bumping, and drilling. Many also use restricted keyways so keys cannot be freely copied. A standard builder-grade lockset has none of these protections.
Are the original Kwikset locks on my Lakewood home a problem?
They are not broken just because they are old, but they are basic hardware, and many Lakewood homes still have them. If you want stronger protection against picking, bumping, or drilling, upgrading the exterior deadbolts is a sensible step. Call (323) 997-8867 to discuss your doors.
Can you install high-security locks on a mid-century door?
Usually yes. We inspect the door, bore, and jamb first. Sometimes an older seized deadbolt or a worn strike plate needs attention, and we address that during the same visit.
Do high-security keys prevent copies?
Restricted-keyway systems limit duplication to authorized channels, which gives you much better control than a common key. We explain how additional keys are ordered for the specific system you choose.
Can a retail store at Lakewood Center get restricted keys and a master-key setup?
Yes. We can set up restricted keys and master-key arrangements for businesses with multiple staff. Describe your doors and who needs access when you call (323) 997-8867.
Do you have a shop I can visit?
No. Crenshaw Lock Company is fully mobile with no storefront. We come to your home or business anywhere in Lakewood, 24/7.
How much will it cost?
It depends on the system you choose, the number of doors, the condition of the door and frame, and whether it is residential or commercial. We explain the options on site so you can decide what fits.
Should I upgrade locks when I buy a house in Lakewood?
It is a smart time to do so. You cannot know who has copies of the old keys, and new high-security cylinders give you fresh, controlled keys. Call (323) 997-8867 to schedule it around your closing.
