Most of La Puente was built in the 1950s and 60s, and a lot of those single-story stucco tract homes still have the entry hardware the builder put in. A builder-grade deadbolt can be opened by a bump key or a basic pick in the hands of someone who knows how, and the soft brass and thin strike plates behind it are not much of a barrier either. High security locks are designed to close those gaps with tighter tolerances, hardened pins and inserts, and keys that cannot be copied at a hardware-store kiosk.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and owner and lead tech David Shar has seen how the weak points differ from door to door. We are fully mobile, so there is no shop to visit. We come to your property, look at the door, the frame and the way it is used, and install hardware that fits what you actually need to protect.

A high security cylinder is only as strong as the door around it. Sun-warped slabs, loose strike plates and short screws can undo the benefit of a good lock, so we look at the whole opening. Whether it is a family home near La Puente Park, a rental with a converted garage unit, or a shop on Valley Boulevard, the goal is a lock that works smoothly every day and resists the common ways of getting past it.

How it works in La Puente

  1. 1

    Talk through what you are protecting

    Call (323) 997-8867 any hour. We ask about the door, who has keys, whether there have been break-in attempts, and whether you want one key for several doors. That tells us whether you need a single cylinder or a full system.

  2. 2

    Inspect the door and frame on site

    We come to you and check the slab, the latch bore, the strike plate and the frame. In older tract homes we often find sticking deadbolts from door movement, which we correct so the new lock turns freely.

  3. 3

    Choose the right high security hardware

    We explain the options for pick, bump and drill resistance and for restricted keyways, then recommend hardware suited to your door and budget. You decide before we begin.

  4. 4

    Install and reinforce

    We fit the new cylinder or deadbolt, and where it makes sense add a reinforced strike plate with longer screws that reach the framing. We align everything so the bolt throws cleanly.

  5. 5

    Cut and test keys

    Keys are cut and tested, and we walk you through how restricted keys are duplicated so you know how to order extras. Multiple doors can be keyed alike if that suits a house and an ADU.

  6. 6

    Final check and handoff

    We test the lock repeatedly from both sides, confirm the door closes and latches normally, and leave you with the keys and any key-control paperwork that applies.

What affects the price

  • The grade and brand of lock chosen, since higher levels of drill and pick resistance involve more complex hardware.
  • Whether you need one cylinder or several, including keyed-alike setups across a main house and a converted-garage unit.
  • The condition of the door and frame, such as warped slabs or loose strike plates that need realignment or reinforcement.
  • Door type: wood residential doors, apartment doors and aluminum storefront doors each use different cylinders and hardware.
  • Restricted keyway and key-control options, and how many extra keys you want cut.
  • Time of service, since after-hours and emergency calls differ from scheduled installs.

Why La Puente chooses us

  • Fully mobile service: the work happens at your door, with no storefront trip and no leaving the property unsecured.
  • In business since 1987, with owner and lead tech David Shar bringing long experience with older tract-home hardware.
  • We look at the door and frame, not just the lock, because a strong cylinder in a weak opening gives a false sense of security.
  • Available 24/7, so a failed deadbolt or a break-in aftermath can be handled without waiting for business hours.
  • We explain the tradeoffs plainly, including when standard quality hardware is enough and high security is not worth it.
  • Experience with both residential and commercial openings, from stucco homes to aluminum storefront doors.

High Security Locks across La Puente

La Puente sits along the I-10 and SR-60 corridors, and its neighborhoods mix older tract homes with newer additions. In Hudson and Sunset, and on the Valinda and Bassett sides of town, we regularly see 1950s and 60s single-story stucco homes still using original or builder-grade deadbolts. Years of heat can warp wood doors so the bolt binds, and that is often the first sign a lock is due for replacement. In ZIP codes like 91744, 91746 and 91747, upgrading the front and back entries to high security cylinders is a practical step for many homeowners.

Rental properties bring their own needs. Converted garages and ADUs add doors, and landlords often want the main house and the unit on a keyed-alike or controlled system after a tenant change. A restricted keyway helps because keys cannot be copied casually, which matters when tenants come and go.

Along Valley Boulevard and the Hacienda Boulevard retail strip, small businesses in aluminum storefronts depend on narrow-stile locks and pivots that take daily abuse. When a storefront deadbolt fails, a same-day cylinder swap to a more resistant model protects the shop. Whether you are near The Donut Hole, off Amar Road or by La Puente Park, we come to you.

High Security Locks in La Puente — FAQs

What makes a lock high security?
High security locks use tighter tolerances, hardened components and special pin designs to resist picking, bumping and drilling. Many also use restricted keys that are hard to copy without authorization.
Do you work in La Puente at night?
Yes. We are available 24/7 and fully mobile, so call (323) 997-8867 at any hour to discuss your situation.
Will a high security lock fix my sticking deadbolt?
Sometimes the lock is fine and the door has shifted. We check alignment first and correct it, then replace the lock if it is worn out or underpowered for your needs.
Can I have the house and my ADU keyed alike?
Yes. We can set up the main house and a converted-garage unit so one key works for both, or keep them separate with a master arrangement. Call (323) 997-8867 to plan it.
Can you upgrade a storefront door on Valley Boulevard?
Yes. We service aluminum storefront doors and can swap failed cylinders or deadbolts with more resistant commercial hardware, often the same day.
Are restricted keys harder to copy?
Yes. Restricted keyways are protected so extra keys generally must be ordered through authorized channels, which gives you more control over who has access.
Is a high security lock worth it for an older tract home?
It can be, especially when the existing deadbolt is builder-grade. The benefit is greatest when the strike plate and frame are also reinforced, so we look at the whole door.
Do I need to come to a shop?
No. Crenshaw Lock Company is mobile only. We come to your home or business, and you can reach us at (323) 997-8867.
