Installing a lock sounds simple until the door in front of you has a bore that is slightly off, a jamb that has shifted, or a finish that has to match the rest of the house. In Cerritos, where so much of the housing was built out in the 1970s as upscale two-story tract homes and townhome communities, we see a wide range of doors: original solid entry doors, newer replacement doors, side-yard gates, garage entry doors and patio slider hardware. Each one calls for a different approach to getting a lock fitted properly.
Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and David Shar leads the work. We are fully mobile, so there is no storefront to visit. We come to you, look at the door, and install the lock in place. That matters for installation work, because the right lock depends on the door's thickness, its material, the strike side of the frame and how you actually use the entry.
Whether you are adding a first deadbolt to a new door, putting a keypad on a back entry, or outfitting a small office with new hardware, the goal is the same: a lock that fits cleanly, operates smoothly and gives you the security you expected when you bought it. We are available around the clock, including nights and weekends, for installs that cannot wait.
How it works in Cerritos
- 1
Talk through the door and the goal
When you call (323) 997-8867, we ask what the door is, whether it is new or has never had a lock, and what you want: a standard keyed deadbolt, a keypad, a smart lock, or a keyed-alike set across several doors. That helps us bring suitable hardware.
- 2
Assess the door and frame on site
We check door thickness, material, existing bore holes, backset and the condition of the jamb. Solid wood, steel, fiberglass and aluminum storefront doors each need different handling, and a frame that has shifted may need attention before a lock will work well.
- 3
Choose the hardware with you
We go over options that suit the door and how it is used, including finish, grade, keying and whether you want smart or keypad features. We explain tradeoffs plainly so you decide with full information.
- 4
Prepare and install
We mark and drill new openings where needed, fit the latch and strike, and mount the lock body and trim. Where a door is already bored, we match the existing prep. We take care to protect the door's finish and keep the work tidy.
- 5
Align, test and reinforce as needed
We cycle the lock repeatedly with the door open and closed, check that the bolt throws fully into the strike, and adjust the alignment. If the strike or jamb needs reinforcement, we talk with you about it.
- 6
Hand over keys and walk you through it
You receive your keys or codes, and for keypad and smart locks we walk through setup, user codes and basic operation. We clean up before leaving.

What affects the price
- The type of lock chosen: a basic keyed deadbolt, a high-security cylinder, a keypad or a smart lock all differ in hardware cost and setup time.
- Whether the door is already bored or needs new holes drilled, which changes the labor involved.
- Door material and condition, since solid wood, steel, fiberglass and aluminum storefront doors are each worked differently.
- The number of locks and whether they should be keyed alike, which affects hardware and time on site.
- Frame or strike reinforcement, if the jamb has shifted or the door needs added strength.
- The time of day, since night, weekend and holiday calls are handled differently from scheduled daytime work.

Lock Installation across Cerritos
Cerritos was incorporated in 1956 as Dairy Valley and renamed in 1967, and much of it was built out in the 1970s. Around Cerritos Towne Center, in ZIP code 90703, many two-story tract homes and townhome or condo communities are now being updated with keypads and smart locks, often right after a home purchase. A new owner might want a fresh deadbolt on a side door, a keypad on the garage entry, or a consistent set of keys for every door.
The commercial side of the city is just as active. In the Los Cerritos Center district, tenants and managers often need new hardware installed on back-of-house doors, storerooms and office entries, and aluminum-storefront doors have their own requirements for latches and cylinders. Near Cerritos Auto Square, dealership and service-area buildings use master-keyed commercial hardware, and we can help with additional doors that need to fit into an existing keying structure.
We travel the SR-91, I-605, South St, Del Amo Blvd and Bloomfield Ave corridors, and can come to areas near the Cerritos Library, the Civic Center and the Cerritos Center for the Performing Arts. Call (323) 997-8867 and we will come to your door.
