A standard builder-grade deadbolt is designed to keep an honest door closed. It is not designed to stand up to someone who knows how to pick a pin-tumbler cylinder, bump a key, or drive a drill through the face of a lock. High security hardware is built to resist exactly those methods, and it pairs the lock with a restricted key, so copies cannot be cut at just any hardware counter. In Reseda, where so many doors still carry original or decades-old hardware, upgrading the lock is often the single most useful change you can make.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and owner and lead tech David Shar knows the San Fernando Valley's mix of older homes, apartment stock and small storefronts well. We are mobile only. There is no shop to drive to; we bring the hardware and tools to your door, whether that is a stucco bungalow near Reseda Park or a storefront on Sherman Way.

A good high security lock is only as strong as the door and frame around it. Much of our work in Reseda is therefore a combination of lock selection, strike and frame correction, and key control. We will tell you plainly what a given door can support, and we will not sell you a premium cylinder if the real weakness is a loose frame or a hollow door.

How it works in Reseda

  1. 1

    Talk through the threat and the door

    Call (323) 997-8867 and tell us what is going on: a break-in attempt, a tenant turnover, a lost key, or a planned upgrade. We ask about the door, the frame and who needs keys, so we arrive with suitable hardware.

  2. 2

    Inspect the door, strike and frame

    On site we look at the door material, the deadbolt bore, the strike plate and the screws holding it. Older Reseda homes often have frames that have shifted over the years, and a misaligned bolt undermines even an excellent lock.

  3. 3

    Choose the right level of protection

    We explain the options in plain language: pick-resistant cylinders, bump-resistant pin designs, hardened inserts that resist drilling, and restricted keyways with controlled key duplication. You decide what fits your risk and budget.

  4. 4

    Install and reinforce

    We fit the new lock, correct or reinforce the strike and frame where needed, and use longer screws into the framing so the door resists force as well as the cylinder resists tampering.

  5. 5

    Test, cut keys and set up key control

    We operate the lock repeatedly with the door open and closed, confirm smooth bolt throw, and hand over keys. For landlords and businesses we talk through who may authorize additional copies and how to track them.

What affects the price

  • The grade and brand of the lock: restricted-keyway, drill-resistant cylinders cost more than a basic deadbolt upgrade.
  • How many doors or units are being done, since multi-door jobs such as an apartment building let us work efficiently.
  • The condition of the door and frame: realigning a settled frame, replacing a strike or reinforcing a weak jamb adds labor and parts.
  • Key control needs, including how many restricted keys you need and whether keying multiple locks alike is desired.
  • Whether the work is a scheduled visit or an urgent after-hours call, and whether existing hardware must be removed first.
  • Door type, such as wood, metal or storefront glass-and-aluminum, which affects which locks will physically fit.

Why Reseda chooses us

  • Fully mobile and available 24/7, so a forced-entry attempt at night does not have to wait until a shop opens.
  • In business since 1987, with experience across the Valley's older housing stock and small commercial doors.
  • We look at the whole door system, not just the cylinder, which matters on earthquake-settled frames.
  • We explain what a lock does and does not protect against, and we will say when a cheaper fix is enough.
  • Restricted-key options for landlords and shop owners who want more control over who can copy a key.
  • One owner-led operation, so you deal with a tech who is accountable for the work.

High Security Locks across Reseda

Reseda's housing makes high security upgrades especially practical. Much of the area south and north of Sherman Way is post-war tract housing from the 1940s and 50s: small stucco bungalows and ranch houses that often still carry original or builder-grade locks. The 1994 Northridge earthquake was centered in Reseda, and decades later many of those door frames have settled enough that deadbolts bind or no longer line up with the strike. In a home in the Reseda Park residential area, a typical job is realigning the strike, fixing the jammed bolt and fitting a pick- and bump-resistant cylinder in the same visit.

Along Reseda Blvd, Sherman Way and Victory Blvd, mid-century dingbat apartments create a steady need for rekeying and restricted keys. A property manager turning over units between tenants benefits from a keyway that cannot be casually duplicated, since old keys from past tenants are a real exposure. The same logic applies to the shops of the Reseda Blvd commercial district, and to a small retail business near the Reseda Theatre marquee on Sherman Way that has had an attempted forced entry and needs a drill-resistant deadbolt and fresh keys.

We serve ZIP codes 91335 and 91337, from the streets around Reseda Park and Reseda Park Lake and the Reseda Recreation Center to the Sepulveda Basin edge, and we travel Vanowen, Saticoy, Roscoe, Tampa, Wilbur and US-101 to reach you. Call (323) 997-8867 any hour.

High Security Locks in Reseda — FAQs

What makes a lock high security?
A high security lock resists common attacks such as picking, bumping and drilling, and usually uses a restricted key that is harder to copy. It is a step above a standard builder-grade deadbolt.
Will a high security lock work on my older Reseda home's door?
Usually yes, but the door and frame matter. Many post-war homes here have frames that have settled since the 1994 earthquake, so we check alignment and reinforce the strike. Call (323) 997-8867 to describe your door.
Can you upgrade locks after an attempted break-in?
Yes. We are mobile and available 24/7, so we can secure the door, inspect the damage to the frame and install a stronger lock and new keys. Call (323) 997-8867.
I manage apartments on Reseda Blvd. Can you rekey several units?
Yes. We rekey multiple units between tenants and can discuss restricted keys so former tenants' copies stop working and new copies are controlled.
How is the price determined?
Price depends on the lock grade, number of doors, door and frame condition, key control needs and timing. We explain the factors before work begins rather than guessing over the phone.
Can high security keys be copied at a hardware store?
Restricted keys are designed so that duplication is limited to authorized channels. That is a major reason landlords and businesses choose them.
Do you have a shop in Reseda I can visit?
No. We are fully mobile and come to you, wherever you are in Reseda. Call (323) 997-8867 to schedule or request an urgent visit.
Will a drill-resistant lock fix a deadbolt that sticks?
Not by itself. A sticking bolt is often a frame alignment problem. We correct the strike or frame and install the new lock so it operates smoothly.
