A business lock does a different job than a house lock. It has to handle dozens of key holders, daily traffic, fire-code rules, and the occasional employee who leaves without returning a key. In Glendora, that range is wide: a boutique storefront in a historic Glendora Village building has very different needs than a South Glendora light-industrial unit or a professional office near Citrus College. Our commercial work is built around those differences rather than one standard package.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, led by owner and lead technician David Shar. We are completely mobile. There is no shop to visit; we bring tools, key-cutting capability, and common commercial hardware to your site, so the work happens at the door where the problem is. We are available around the clock, which matters for a business that discovers a broken lock or a forced door at closing time or early in the morning.

Whether you need a single cylinder replaced after a lockout, a full rekey after staff turnover, or a master key system that organizes who can open what, the goal is the same: a door that secures your property, lets the right people in easily, and meets the practical requirements of how your building is used. Call (323) 997-8867 and we will talk through the situation before anyone drives out.

How it works in Glendora

  1. 1

    Tell us about the door and the problem

    When you call, we ask what kind of business it is, what the door looks like, and what happened: a lockout, a broken key, a failed latch, or a staffing change. Photos of the hardware can help us bring the right parts.

  2. 2

    Assess the hardware on site

    At your location we look at the lockset, cylinder, strike, door, and frame. Commercial doors often fail because of alignment or worn closers rather than the lock itself, so we check the whole opening before recommending anything.

  3. 3

    Get a clear recommendation

    We explain the options in plain language, such as rekeying versus replacing, a standard grade versus a higher-security cylinder, or adding a keyed-alike or master key arrangement. You approve the plan before work begins.

  4. 4

    Complete the work at the door

    Because we are mobile, rekeying, cylinder swaps, deadbolt upgrades, exit device repair, and key cutting are done where you stand. We try to keep the business open and the door usable throughout.

  5. 5

    Test, label, and hand over keys

    We test every lock with the new keys, confirm the door latches and closes properly, and hand over keys. For multi-key setups we can help you keep a record of which keys open which doors.

  6. 6

    Plan follow-up security

    If we notice weak spots like an exposed hinge, an unprotected rear door, or a lock that is overdue for replacement, we point them out so you can plan upgrades on your schedule.

What affects the price

  • The type of work: a lockout, rekey, cylinder replacement, or full hardware installation are all different scopes of labor and parts.
  • The number of doors or cylinders involved, since a multi-door rekey or master key system takes more time than a single entry.
  • Hardware grade and security level, from standard commercial cylinders to restricted-keyway or high-security options.
  • Door and frame condition, because a misaligned, damaged, or worn door may need repair for the new lock to work properly.
  • Time of day and urgency, as after-hours and emergency calls differ from scheduled daytime work.
  • Specialty hardware such as panic bars, electrified strikes, or keypad and access control components, which add parts and setup.

Why Glendora chooses us

  • Fully mobile service from a team operating since 1987, with owner David Shar leading the work.
  • 24/7 availability, useful for businesses that face break-ins, lockouts, or staff changes outside normal hours.
  • Experience across storefronts, offices, warehouses, and industrial doors, not just residential locks.
  • We explain options honestly and do not push replacement when a rekey or repair will solve the problem.
  • Attention to the whole opening, including strike, frame, and closer, so the fix lasts.
  • No storefront or showroom overhead; the work is done at your door.

Commercial Locksmith across Glendora

Glendora businesses sit in several distinct settings. In Glendora Village, the historic downtown, early-1900s buildings and boutique storefronts often have older doors, original frames, and a mix of old and newer hardware. A lockout or cylinder replacement there may require fitting modern commercial hardware to an older door without damaging its character. Shops along Glendora Ave and Grand Ave also tend to need quick turnaround so the doors are secure and the shop can open on time.

Further south, South Glendora and the corridors around Lone Hill Ave and Route 66 (Alosta Ave and Foothill Blvd) include offices, service businesses, and small industrial or warehouse spaces. These sites usually need rekeys after staff changes, roll-up or rear door security, and panic hardware that works reliably. Businesses near Citrus College and along the Interstate 210 (Foothill Freeway) corridor often want organized key control for multiple employees or tenants.

We work throughout ZIP codes 91740 and 91741, from the village core to North Glendora and its foothill properties near Big Dalton Canyon and the Glendora Country Club. Some professional offices and home-based businesses in North Glendora sit behind gates or on private drives, where higher-end hardware is common. Wherever you are in town, call (323) 997-8867 and we will come to you.

Commercial Locksmith in Glendora — FAQs

Do you offer commercial locksmith service in Glendora at night or on weekends?
Yes. We are available 24/7 and fully mobile, so we can come to your Glendora business after hours, on weekends, and on holidays. Call (323) 997-8867 to reach us.
Can you rekey my business after an employee leaves?
Yes. Rekeying changes the internal pins so old keys no longer work, without replacing the lock hardware. It is often the most practical response to staff turnover, and we can do it on site.
Do you work on older storefront doors in Glendora Village?
Yes. Historic buildings often have older doors and frames. We assess the opening first and choose hardware that fits properly while protecting the door where possible.
What is a master key system and does my business need one?
A master key system lets different keys open different doors, with a top-level key opening all of them. It suits offices, multi-tenant buildings, and warehouses with several access levels. We can talk through whether it fits your site.
Can you repair or install panic bars and exit devices?
We service and install commercial exit hardware, including panic devices. Proper function matters for both security and safe exit, so we test it thoroughly after the work.
Do you have a shop I can visit?
No. Crenshaw Lock Company is entirely mobile. We come to your location in Glendora with the tools and hardware needed. Call (323) 997-8867 to arrange service.
How is commercial locksmith pricing determined?
It depends on the type of work, number of doors, hardware grade, door condition, and time of day. We explain the scope and what affects cost before work begins.
Can you help after a break-in attempt?
Yes. We can repair or replace damaged locks, assess the door and frame, and suggest ways to strengthen the entry so your business can be secured again.
