Installing a lock where none existed before is a different job from swapping one out. There is no existing bore to match, no known backset, and often no clear idea of what the door can handle. In Claremont that might be a new gate on a hillside property, a freshly framed door on a converted garage, a studio built behind a bungalow, or a storage room that has simply never been secured. Each opening needs hardware chosen for the door it is going on.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and owner and lead technician David Shar has installed hardware on a wide range of door types over those years. We are a mobile-only business. There is no storefront to visit, so the hardware, the drill and boring tools, and the know-how arrive at your door. That makes it easy to get the work done properly in one visit instead of making a hardware store run and guessing at what fits.

Claremont is also a city that cares about how things look. Many homes near the Village are historic, and a visible new deadbolt on a century-old door should not look like an afterthought. We pay attention to finish, to trim, and to how much wood is removed, so the new lock secures the opening without damaging the character of the door or frame.

How it works in Claremont

  1. 1

    Tell us about the door and what you need

    Call (323) 997-8867 and describe the opening: interior or exterior, wood, metal, or glass, new construction or an older door that never had a lock. Tell us who uses it and how. We can talk through what kind of lock suits the situation before anyone drives out.

  2. 2

    We come to you

    Because we are fully mobile and available 24/7, we travel to your Claremont address with a range of deadbolts, knob and lever sets, and related hardware. We inspect the door itself first, including its thickness, material, condition, and the frame around it, since those details decide what can be installed safely.

  3. 3

    Choose the hardware

    We go over practical options on site: a single-cylinder deadbolt, a keyed lever for a utility room, or a keyless or smart option where it makes sense. We explain the tradeoffs in plain language and you decide. If a door is too thin or weak to hold a lock well, we say so and discuss reinforcement.

  4. 4

    Mark, drill, and fit

    We measure the height and backset, mark the door carefully, and bore the cross hole and edge hole with proper tools so the cut is clean. We mortise the latch plate flush, fit the lock, and set the strike in the frame so the bolt throws smoothly without binding.

  5. 5

    Reinforce where it counts

    A good lock in a weak frame is only half a solution. Where the frame or jamb is thin, we can discuss a longer strike plate with longer screws that reach the framing behind the trim, which helps the installation hold up under force.

  6. 6

    Test, key, and walk through

    We cycle the lock repeatedly with the door open and closed, confirm the keys work, and show you how everything operates. You get the keys and a clear understanding of what was installed, so there are no surprises later.

What affects the price

  • The type of lock chosen, since a basic keyed knob set, a grade-rated deadbolt, a multipoint system, and an electronic or smart lock differ widely in hardware cost.
  • The door material and condition. Solid wood, hollow-core, metal, and glass doors each call for different tools and techniques, and a door with no existing bore takes more work than a swap.
  • The number of locks or doors, because several openings at one property can be handled in a single visit.
  • Whether the frame or jamb needs reinforcement, such as a strike plate upgrade or added backing, to hold the new lock properly.
  • Keying preferences, including keyed-alike sets so one key works several locks, or integration with an existing key system.
  • The time of the visit, since evening, overnight, weekend, and holiday calls differ from scheduled daytime work.

Why Claremont chooses us

  • Fully mobile service from a business operating since 1987, so the installation happens at your door with no shop trip involved.
  • Available 24/7, which matters when a new door goes in late or a space needs to be secured the same day.
  • Careful work on older doors. We understand that period homes near the Village have wood and finishes worth protecting, so we keep cuts clean and minimal.
  • Honest assessment of the door. If it is too thin or damaged to take a lock well, we tell you plainly instead of installing something that will not hold.
  • Hardware matched to the use, from a simple storage-room latch to a high-security deadbolt, rather than selling the same product to everyone.
  • Owner-led expertise. David Shar leads the work, so the experience behind the job is the same whether it is a single door or several.

Lock Installation across Claremont

Claremont has an unusually varied mix of buildings for one small city. Around Claremont Village and the streets off Yale Ave, many 1900s to 1920s Craftsman bungalows have been added to over the decades with converted garages, back studios, and new interior doors. Those additions often need new locks installed where none ever existed, and we try to fit hardware that sits comfortably alongside original details. In ZIP code 91711, we also see new doors added to retail spaces and offices near the Village.

North Claremont and the hillside Claraboya area offer newer homes, often with side gates, patio doors, detached rooms, and sheds that benefit from proper locks. Properties near Claremont Hills Wilderness Park and the foothills are often a bit more secluded, which makes solid hardware and well-anchored strike plates worth thinking about. Around The Claremont Colleges, off-campus housing, small offices, and new storage or workspace openings can all call for fresh installations, and we can discuss keying that works with how a group of people will use the space.

Whether you are off Foothill Blvd, near Indian Hill Blvd, up toward Base Line Rd, or just off Towne Ave or Mills Ave, we come to you. Reaching Claremont from the I-10 or SR-210 is a routine trip for a mobile service, and you can call (323) 997-8867 at any hour to arrange an installation.

Lock Installation in Claremont — FAQs

Can you install a lock on a door that never had one?
Yes. Installing on a bare door is a common job. We measure, bore the holes, fit the latch and strike, and test the result. Call (323) 997-8867 to describe the door and we can talk through the best option.
Will a new lock damage my historic Craftsman door?
We work to keep cuts clean and minimal, and we choose hardware whose finish suits the door. Older solid-wood doors can usually take a modern deadbolt well, though we will tell you honestly if a particular door is too fragile or thin.
Do you come out at night or on weekends in Claremont?
Yes. We are 24/7 and fully mobile, so you can call (323) 997-8867 at any hour. We do not make timing promises, but we will work with you on getting the opening secured.
Can you install locks on a converted garage or backyard studio?
Yes. These are common in Claremont. We look at the door and frame, suggest suitable hardware, and can match keying to your main house locks so you carry fewer keys.
What lock types can you install?
We install deadbolts, knob and lever sets, and electronic or smart locks where the door suits them. We explain the pros and cons of each in plain terms so you can choose what fits.
Do you offer keyed-alike locks for multiple doors?
Yes. We can set several new locks to work with a single key, which is handy for a house with a gate, a side door, and a studio. Ask when you call.
How is the cost of a new installation determined?
It depends on the lock type, the door material, how many openings there are, whether the frame needs reinforcement, and the time of day. We discuss these factors up front when you call (323) 997-8867.
Do you have a shop I can visit in Claremont?
No. We are a mobile-only business, so there is no storefront. We bring the tools and hardware to your location, which lets us size and fit the lock right at your door.
