A high security lock is not just a stronger-looking deadbolt. It is a cylinder engineered to resist the ways locks are actually defeated: picking, bumping, drilling, and unauthorized key copying. Many of them pair with restricted keyways, meaning duplicate keys can only be cut with authorization. For many Monterey Park properties, that is a meaningful upgrade over the standard builder-grade hardware still found on older doors.
Monterey Park has a wide mix of buildings. Hillside homes from the 1950s and 60s sit above denser flats of mid-century stucco houses, apartments and condos, and the Atlantic Blvd and Garvey Ave corridors are lined with restaurants, markets and offices behind aluminum-storefront doors. Each of these calls for a different approach, and a lock that suits a split-level front door may be wrong for a narrow-stile storefront or a rental that changes tenants often.
Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, led by owner and lead technician David Shar. We are mobile only, with no storefront to visit. We assess the door on site, explain the realistic options, and install the hardware where it belongs, so you are not guessing from a catalog.
How it works in Monterey Park
- 1
Talk through the problem
Call (323) 997-8867 any hour. We ask what you want to protect, whether you have had a break-in or key-control worries, and what kind of door and frame you have, so we arrive with suitable hardware in mind.
- 2
On-site door assessment
A lock is only as strong as the door around it. We check the door material, thickness, bore holes, strike plate, frame condition and hinges. On older hillside homes and aluminum storefronts, this often shapes which cylinder or deadbolt makes sense.
- 3
Choose the right level of protection
We go over high-security cylinders, restricted keyways and, where appropriate, electronic or smart-compatible deadbolts. We explain what each resists and what it does not, so you choose based on your actual risk.
- 4
Install and reinforce
We remove the old hardware, fit the new lock, and where needed upgrade the strike plate, add longer screws or reinforce the jamb, since weak frames are a common failure point.
- 5
Key setup and testing
We cut and test keys, confirm smooth operation from both sides, and explain how restricted key duplication works. For multi-unit properties we can discuss keying several locks in an organized way.

Walkthrough and follow-up advice
Before leaving, we show you how the lock works, how to care for it, and what to do if a key is lost, so you are not left with questions.

What affects the price
- The type of lock chosen: a high-security cylinder alone differs from a full deadbolt set or an electronic model.
- The number of doors or cylinders, especially for apartment buildings, offices or restaurants with several entrances.
- Door and frame condition, since reinforcement of a worn jamb or strike area adds parts and labor.
- Key control level: restricted keyways and the number of keys needed affect the total.
- Door type, such as a residential wood door versus an aluminum storefront with narrow stiles or exit hardware.
- Timing: after-hours or emergency requests may be priced differently than scheduled work.
Why Monterey Park chooses us
- Fully mobile and 24/7, so work happens at your door, whether that is a hillside home or an Atlantic Blvd storefront.
- In business since 1987, with owner David Shar directly involved.

- Practical help for landlords who need organized rekeying and key control between tenant turnovers.
High Security Locks across Monterey Park
Monterey Park's layout shapes its security needs. In Monterey Highlands and the slopes above, 1950s and 60s single-family homes often have older hardware, and more owners are adopting electronic and smart deadbolts. We help with the high-security side of those upgrades, and can also assist when a dead battery leaves someone locked out of a split-level. Down in the flats, including the East LA border flats, mid-century stucco houses, apartments and condos in ZIP codes 91754 and 91755 often benefit from stronger cylinders and better strike reinforcement.
Along Atlantic Blvd and Garvey Ave, restaurants, markets and offices rely on aluminum-storefront deadbolts, roll gates and exit hardware that see heavy daily use. High-security cylinders can add key control in places where employees come and go. We also work with landlords of apartments near East Los Angeles College who need rekeying and tighter key control when tenants turn over.
Whether you are near Garvey Ranch, Edison Trails Park or just off I-10, SR-60 or Garfield Ave, we come to you. Call (323) 997-8867 and we will talk through your door.
