Most of Pico Rivera was built in a hurry after the war. The Pico and Rivera districts filled with single-story stucco tract homes on uniform lots, and a great many of those doors still carry the builder-grade lockset and original deadbolt that went in decades ago. Those hardware pieces were made to keep a door closed, not to resist someone who knows how to pick, bump or drill a cylinder. A high security lock is a different class of product, and upgrading is one of the more meaningful security changes a homeowner or shop owner can make.

High security cylinders use tighter manufacturing tolerances, additional or unusual pin and sidebar designs, and hardened inserts that frustrate drilling and prying. Many pair with restricted keyways, meaning copies can only be cut with authorization instead of at any hardware-store kiosk. That matters if you have had tenants, contractors, roommates or former employees who once held a key.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and owner and lead technician David Shar and the team work entirely from mobile service vehicles. There is no storefront to visit. We bring the tools and hardware to your door in Pico Rivera, assess what you actually have, and recommend only what makes sense for that door.

How it works in Pico Rivera

  1. 1

    Call and describe the door

    Call (323) 997-8867 any hour. Tell us whether it is a front door, a gate, a storefront or an interior office, what lock is on it now, and what worries you, such as a past break-in, lost keys or a tenant change.

  2. 2

    On-site assessment

    We come to you and look at the whole setup, not just the cylinder. The door, the frame, the strike plate and the latch all affect how well a lock holds up, and a strong cylinder in a weak frame is wasted money.

  3. 3

    Choose the right level of protection

    We explain the options in plain language: pick- and bump-resistant cylinders, drill-resistant hardware, and restricted key systems. You decide how much protection suits the property and how many keys you need.

  4. 4

    Installation and reinforcement

    We remove the old hardware and install the new lock, fitting it so the bolt throws smoothly. Where it helps, we add a reinforced strike plate or longer screws so the frame is not the weak point.

  5. 5

    Testing and key handoff

    We test the lock from both sides, cycle it repeatedly, and hand over your keys along with guidance on how key copying works for your system so you can control who has access.

What affects the price

  • The grade and brand of lock you choose, since restricted keyway and drill-resistant designs vary widely in cost.
  • How many doors or cylinders are being upgraded, and whether they can be keyed alike to a single key.
  • The condition of the door and frame, including whether a strike plate or reinforcement is needed on older stucco-era frames.
  • Whether the job is residential or commercial, such as an aluminum storefront door that needs a specific cylinder or mortise fit.
  • The number of restricted keys needed and any authorization requirements for extra copies.
  • Time of day and urgency, because after-hours emergency calls differ from scheduled upgrades.

Why Pico Rivera chooses us

  • Fully mobile since 1987, so the work is done at your door with no trip to a shop.
  • Open 24/7, which helps when a break-in or a lost key means you need the lock changed right away.
  • We look at the door and frame as a system and will tell you honestly if a standard lock would do the job.
  • Experience with both aging 1950s tract-home hardware and commercial storefront and strip-retail doors.
  • Clear explanation of restricted keys so you know exactly who can and cannot copy your keys.
  • Owner-led operation with David Shar, so standards stay consistent.

High Security Locks across Pico Rivera

Pico Rivera's housing stock shapes what we see. In Pico, Rivera and North Pico Rivera, many of the 1950s tract homes still have their original deadbolts, often worn or corroded, particularly toward the river-adjacent north end. Swapping a tired deadbolt for a high security cylinder is a straightforward upgrade for homes in ZIP codes 90660, 90661 and 90662, and we can often key the front, back and garage side doors alike.

Commercial needs are just as common. Strip retail along Whittier, Washington and Rosemead Boulevards and the shops around Pico Rivera Towne Center often use aluminum storefront doors that need a specific cylinder, and light-industrial units near the I-605 and San Gabriel River corridor benefit from drill-resistant hardware. Venues and vendors around the Pico Rivera Sports Arena sometimes need a quick commercial lock change or secure padlock for event setup.

Whether you are near Smith Park, Streamland Park or the Whittier Narrows Recreation Area, or just off I-5 or I-605, we come to you. Call (323) 997-8867 and we will meet you wherever the door is.

High Security Locks in Pico Rivera — FAQs

What makes a lock high security?
High security locks resist common attacks such as picking, bumping and drilling through tighter tolerances, special pin or sidebar designs and hardened components. Many also use restricted keys that cannot be freely copied.
Is it worth upgrading the original deadbolt on a 1950s Pico Rivera home?
Often yes. Original or builder-grade deadbolts have decades of wear and are easy to defeat. Call (323) 997-8867 and we can look at your door and recommend a fitting upgrade.
Do you offer high security locks for businesses on Whittier Blvd?
Yes. We work with aluminum storefront doors, strip-retail tenants and light-industrial units. We can also extract a broken key and replace the cylinder in the same visit when possible.
Can you come at night or on weekends?
Yes, we are available 24/7 and fully mobile. Call (323) 997-8867 at any hour.
Do I need to replace my door too?
Not usually. We check the door and frame, and often a reinforced strike plate and longer screws are enough. We will tell you plainly if the door itself is the problem.
What is a restricted key?
A restricted key uses a keyway protected so that blanks and copies are controlled. That limits who can duplicate your key, which is useful for rentals, shared properties and workplaces.
Can several doors use the same key?
In most cases yes. We can key front, rear and garage doors alike so you carry one key, while still using high security cylinders.
Do you have a shop I can visit?
No, we are mobile only. We bring everything to your location in Pico Rivera. To schedule, call (323) 997-8867.
