Installing a lock sounds simple until you stand in front of a solid-wood door in a 1920s Spanish Colonial or Tudor home. In San Marino, the doors are often thick, the hardware is often original, and the owners care about how a house looks as much as how it secures. A new lock here has to work, last, and respect the architecture. That is the approach we take with every installation.
Lock installation covers new doors, converted rooms, new garden or pool gates, guest houses, detached garages, and any opening where no lock existed before. It also covers adding a deadbolt where a door only has a knob. Because we are fully mobile, we bring the tools, cylinders, and hardware to your property rather than asking you to visit a shop. We have no storefront; the work happens at your door.
Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, under owner and lead technician David Shar. Many San Marino projects begin with a conversation about what you want to protect and how visible you want the hardware to be. From there we recommend options, from high-security cylinders to discreet smart-lock systems, and install them cleanly so the door looks as though it was always meant to have them.
How it works in San Marino
- 1
Talk through the opening
Call (323) 997-8867 and tell us what the door or gate is, what it is made of, and what it protects. A front entry, a garden gate, a guest house, and a home office each call for different hardware, so we start by understanding the job.
- 2
Assess the door and frame on site
We look at the door thickness, material, frame condition, and any existing bores or mortise pockets. On solid-wood period doors we check for splitting risk and plan the work to protect the finish and the surrounding trim.
- 3
Choose hardware that fits the home
We go over deadbolts, high-security cylinders, mortise sets, and smart-lock options, including how each looks and operates. Finish matching matters in San Marino, so we discuss brass, bronze, and other tones before drilling anything.
- 4
Install with careful preparation
We mark, bore, and fit the lock so the latch and strike align cleanly. Where a new door is involved, we reinforce the strike area and use proper screws so the lock holds up under real force, not just everyday use.
- 5
Key it the way you want
We can set locks to a single key across exterior doors and gates so you are not carrying a ring of keys. We hand over keys and confirm every one works smoothly.
- 6
Test and walk you through it
We operate each lock repeatedly with the door open and closed, check the strike, and show you how any smart or high-security feature works before we finish.

What affects the price
- The type of lock: a standard deadbolt, a high-security cylinder, a mortise set, or a smart lock each carry different hardware costs and installation effort.
- Door material and thickness, since solid-wood and heavy period doors take more careful preparation than a standard hollow or composite door.
- Whether the door is already bored or mortised, or we must create the opening from scratch for a new lock.
- The number of locks and gates involved, and whether you want them all keyed alike to a single key.
- Finish and style matching, such as sourcing hardware that suits vintage brass or other period details.
- Whether the visit is during regular hours or a late-night, weekend, or holiday call, given that we operate 24/7.

- Available 24/7, so a new lock can be installed when the situation calls for it, not only on a business-hours schedule.
Lock Installation across San Marino
San Marino is almost entirely residential, and its housing shapes the work we do. Around the Huntington Library district, many homes are 1920s and 1930s period-revival estates with heavy wood doors and original brass hardware. In those cases, a new installation often means adding a high-security cylinder or a deadbolt without disturbing the character of the entry. Across ZIP code 91108, large lots also mean gates, side doors, garden entrances, and outbuildings that need their own locks.
In the Lacy Park neighborhood, owners often want one coordinated system: new deadbolts on service doors, a safe-grade deadbolt on the main entry, and consistent keying across the property. We have handled projects like a whole-house rekey with a safe deadbolt upgrade after a staff change, and a lost-key situation where every exterior door and garden gate was re-pinned to a single key. Those same principles guide new installations.
The Mission District along Huntington Drive and Mission Street has modest neighborhood-scale commercial space, where new storefront or office doors may need fresh hardware. We travel the main routes, including Huntington Dr, Sierra Madre Blvd, San Gabriel Blvd, Del Mar Ave, and Los Robles Ave, and we work around the city's preservation-minded norms by keeping installations tidy and visually restrained.
