Installing a lock sounds simple until you stand in front of the actual door. A new door may be unbored. An older door may have been drilled for hardware that no longer exists. A glass storefront door may need a lock that fits a narrow aluminum stile. Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and owner and lead tech David Shar built the business around matching the right hardware to the real door, not forcing a generic kit onto it.

Pasadena makes that matter more than most places. The city has a deep stock of 1900s to 1930s Craftsman bungalows and American Foursquares, estates from the 1910s and 1920s, mid-century apartment courts, and aluminum-frame commercial space along Colorado Boulevard and Lake Avenue. Each of these calls for a different approach to cutting, fitting and finishing a new lock.

We are fully mobile, so there is no shop to visit. Our technicians bring the tools and a range of hardware to your property at any hour, look at the door, explain the options in plain language, and install the lock so it throws smoothly and the door closes the way it should.

How it works in Pasadena

  1. 1

    Tell us about the door

    Call (323) 997-8867 and describe what you have: a new door, a door with no lock, or one that needs an added deadbolt. Tell us the material (solid wood, hollow-core, metal, glass in an aluminum frame), whether it is an entry, a side door or a gate, and what level of security you want.

  2. 2

    On-site assessment

    We come to you and inspect the door and frame. We check thickness, edge condition, existing bores, strike plate area and how well the door hangs. A lock is only as strong as the wood or metal around it, so this step decides which hardware makes sense.

  3. 3

    Choose the hardware

    We walk through suitable options, such as deadbolts, knob or lever sets, handlesets, or a keyed entry for a commercial door. If you want a finish that suits a period home, we discuss that before drilling anything, because holes can't be undone.

  4. 4

    Careful installation

    We bore and mortise as needed, using jigs for clean, correctly sized holes. We set the latch and bolt, fit the strike plate and consider reinforcing it so the screws bite into the framing rather than only the trim.

  5. 5

    Test and fine-tune

    We operate every lock repeatedly with the door open and closed, check alignment, and adjust until the bolt extends fully without binding. We make sure the keys work smoothly.

  6. 6

    Handoff

    We hand over the keys, show you how the hardware operates, and answer questions on maintenance. If you want additional locks keyed alike, we can plan that during the visit.

What affects the price

  • The type of lock: a basic deadbolt, a handleset, a higher-security cylinder or a commercial-grade lockset all sit at different levels.
  • The door itself: a new unbored door, an existing bore that needs adapting, or a solid wood door that needs more careful work than a hollow one.
  • How many locks are being installed, and whether they should be keyed alike so one key works throughout.
  • Frame and strike reinforcement, such as stronger strike plates or longer screws, when the frame is worn or weak.
  • Special door types such as glass doors in aluminum storefront frames, which need specific narrow-stile hardware.
  • Timing of the visit, since after-hours and emergency calls are handled differently from scheduled work.

Why Pasadena chooses us

  • Fully mobile, 24/7 service means we meet you at the door instead of asking you to bring it to a shop that does not exist.
  • Serving the region since 1987 gives us long experience with the kinds of doors found across Los Angeles County, from old wood to modern metal.
  • We assess the door and frame before recommending hardware, so you aren't sold a lock the door can't properly support.
  • We take care with period homes, discussing finishes and fit before drilling so original woodwork stays as intact as possible.
  • We handle residential, apartment and storefront installs, so one call covers a home deadbolt or a retail door.
  • We explain choices plainly and give you the pricing factors up front, with no pressure toward upgrades you don't need.

Lock Installation across Pasadena

Pasadena's housing is unusually varied, and lock installation here often comes down to respecting what's already on the door. In Bungalow Heaven and the Craftsman streets nearby, original wood doors are a big part of the home's character. When a new deadbolt is needed on one of these doors, such as a back door that never had one or an added lock for a new owner, we plan the bore carefully to protect the wood and original brass hardware. Madison Heights and Garfield Heights have larger, older homes with heavy doors, where proper strike reinforcement makes a real difference.

Near the Playhouse District, Old Pasadena and the Colorado Boulevard corridor in ZIP codes 91101 and 91103, much of the work is commercial. Aluminum-frame glass doors on storefronts need narrow-stile hardware, and a new business may need locks fitted before opening day. Closer to Caltech and PCC, mid-century apartment courts often need added or upgraded deadbolts at a landlord's request, and tenants appreciate installs that are neat and quick to test.

We travel throughout the city, including Hastings Ranch and the areas around the Rose Bowl, Huntington Hospital and the Norton Simon Museum, using I-210, SR-134 and the Arroyo Seco Parkway as well as Lake Avenue and Fair Oaks Avenue. Call (323) 997-8867 any hour and we will head your way.

Lock Installation in Pasadena — FAQs

Can you install a lock on a door that has never had one?
Yes. We bore the door for the lock and latch, fit the strike plate in the frame and test it. Call (323) 997-8867 and tell us about the door so we can bring suitable hardware.
Do you install locks in Craftsman homes in Bungalow Heaven?
Yes. We plan carefully to protect old wood doors and, where possible, original hardware. We would rather discuss placement and finish with you before drilling than rush the job.
Can you install locks on storefront glass doors along Colorado Boulevard?
Yes. Aluminum-frame glass doors need hardware made for narrow stiles, and we can handle that. For business owners, call (323) 997-8867, including after hours.
Is lock installation different from rekeying?
Yes. Installation adds a new lock where none existed or on a new door. Rekeying changes the internal pins of an existing lock so old keys stop working. Many properties need both.
Do you work at night and on weekends?
Yes, we are available 24/7. Call (323) 997-8867 whenever you need us. Scheduled installs and urgent ones are both welcome.
Do I need to visit a shop to pick out a lock?
No. We are fully mobile and have no storefront. We bring hardware options to your Pasadena home or business and help you choose on site.
Can a landlord have us add deadbolts to several apartment units?
Yes. We can install matching deadbolts across units and can key them alike or individually. Costs depend on lock type, door condition and number of locks.
Will a new lock make my door more secure by itself?
Only partly. A good deadbolt helps, but the door, frame and strike plate matter just as much. We check all three and recommend reinforcement when needed.
