A standard builder-grade deadbolt does the job until someone decides to test it. High security locks are built for that moment. They use tighter tolerances, hardened inserts, specialized pin and sidebar designs, and restricted keyways so the lock resists picking, bumping, drilling and forced entry, and so keys cannot be copied at any hardware kiosk. In West Covina, where so much housing is 1950s and 60s tract construction with original hardware, the upgrade is often the single most meaningful security improvement a property can make.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and owner and lead technician David Shar has watched lock technology and burglary methods change over that time. We are mobile only. There is no storefront to visit. We bring the hardware and tools to your door, look at the actual door, frame and strike, and recommend something that fits instead of selling a one-size-fits-all product.

This service covers single-family homes, apartment buildings, retail suites and medical or office doors. Whether you want one high-security deadbolt on a front door or a keyed-alike system with restricted keys across a whole property, we plan it around how you actually use your doors.

How it works in West Covina

  1. 1

    Talk through your goals and concerns

    Call (323) 997-8867 and tell us what you are protecting and why. Maybe it is a recent break-in attempt, a former tenant or employee who still has keys, or simply an aging lock. We ask about the door, how many users need keys, and whether you want a single lock or a system.

  2. 2

    Assess the door, frame and strike

    A strong cylinder in a weak door is a wasted upgrade. On site we check the door material, the thickness and condition of the jamb, the strike plate and its screws, and whether the existing bore fits the new hardware. Hollow or worn doors in older tract homes sometimes need reinforcement.

  3. 3

    Choose the right level of protection

    We explain the differences between pick-resistant, bump-resistant and drill-resistant designs, and between patent-protected restricted keyways and standard ones. You decide how much key control you want, such as keys that can only be duplicated with authorization.

  4. 4

    Install and reinforce

    We fit the new lock, set the latch and bolt properly, and install a reinforced strike plate with long screws that reach the framing where appropriate. Alignment matters, because a bolt that drags or binds weakens both security and daily use.

  5. 5

    Test and hand over keys

    We cycle every lock and key several times, confirm smooth operation from both sides, and walk you through how to order additional keys under the restricted system. You leave knowing exactly what you have and how to maintain it.

What affects the price

  • The grade and brand of lock you select, since restricted-keyway and drill-resistant designs vary widely in construction.
  • How many cylinders or doors are involved, and whether you want them keyed alike or each on its own key.
  • The condition of the door and frame, including any need for a reinforced strike, jamb repair or bore adjustment.
  • Whether the work is residential, commercial or multi-unit, which affects hardware type and scheduling.
  • The number of restricted keys you need and whether you want key-control or authorization features.
  • Time of day and urgency, since we are available around the clock and after-hours calls differ from scheduled visits.

High Security Locks across West Covina

West Covina is a big suburban city with a wide mix of properties, and the right lock depends on the neighborhood. In the South Hills, between the I-10 and SR-60 freeways, view and hillside homes, some of them gated, often justify higher-end hardware. Owners there ask for restricted keyways on front doors, side gates and garage entries. Across the flatter parts of the city in ZIP codes 91790, 91791, 91792 and 91793, the post-war single-family tract homes in areas like Woodside Village often still carry the original builder hardware and lightweight strike plates, which makes a high-security deadbolt with a reinforced strike a practical upgrade.

Apartment owners and managers along Azusa Ave, Vincent Ave and Amar Rd deal with a different problem: keys that circulate between tenants. A restricted-key system helps control who can copy a key, and combined with a turnover rekey it keeps unit access under the manager's control. The same thinking applies to garden and mid-rise complexes with shared doors and utility rooms.

On the commercial side, the Eastland and Plaza commercial district, Plaza West Covina and Eastland Center bring retail storefronts and back-of-house doors that benefit from pick- and drill-resistant cylinders. The medical district around Emanate Health Queen of the Valley Hospital has offices and storage rooms where controlled keys matter for supplies and records. Wherever you are, from Cortez Park to near Galster Wilderness Park, we come to you.

High Security Locks in West Covina — FAQs

What makes a lock "high security"?
It is built to resist common attack methods. That usually means tighter tolerances, hardened components against drilling, designs that resist picking and bumping, and a restricted keyway so keys cannot be casually duplicated. Call (323) 997-8867 to discuss which features matter for your door.
Will a high security lock stop a break-in by itself?
Not alone. Many forced entries defeat the door, frame or strike rather than the cylinder. That is why we inspect the whole door and often add a reinforced strike plate and long screws alongside the new lock.
Can my existing West Covina tract-home door take a high security deadbolt?
Usually yes. Most standard doors from that era have a standard bore that fits. We check the door's condition and the jamb first, and if it is worn or damaged we explain what reinforcement makes sense.
Can I get extra keys copied at a hardware store?
With a restricted keyway, generally not. Duplication is limited to authorized channels, which is the point. We explain how to order additional keys when we hand over your set.
Do you offer high security locks for apartments and rentals?
Yes. Property owners and managers use restricted keys and rekeying to control access between tenants. Call (323) 997-8867 to talk through a single unit or a whole complex.
Do you work on commercial and retail doors?
Yes. We handle storefront, office and back-room doors, including cylinders and access needs for retail centers and medical offices in the area.
Is there a shop I can visit?
No. Crenshaw Lock Company is fully mobile. We come to your property anywhere in West Covina and handle everything on site.
Can you come out after hours or in an emergency?
We are available 24/7. If a break-in has damaged a lock or you need a property secured at night, call (323) 997-8867 and we will help get it sorted.
