Business locks work harder than the ones on a house. They are opened dozens of times a day, shared among employees, and often installed decades ago. Covina has plenty of both kinds of commercial property: small retail and offices in historic Downtown Covina, and larger service and industrial users along Azusa Ave, Arrow Hwy and the Interstate 10 corridor. Each has its own lock problems.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, led by owner and lead technician David Shar. We are fully mobile, which means there is no storefront to visit. We drive to your location with the tools and hardware to work on site, whether you are locked out at midnight or planning a key-control upgrade for the whole building.

This page explains how our commercial work usually goes in Covina, what affects the cost, and what to expect from us. We do not quote prices without seeing the job, because honest pricing depends on your doors, your hardware and your security goals.

How it works in Covina

  1. 1

    Call and describe the situation

    Phone (323) 997-8867 and tell us what is happening: a lockout, a lost key, a former employee who still has access, or a planned upgrade. We are available around the clock, so you can call after closing or on a holiday.

  2. 2

    We come to your business

    Because we are fully mobile, a technician travels to your Covina location. We ask about the door type, lock brand if known, and whether it is a glass storefront, steel back door or roll-up gate so we bring appropriate hardware.

  3. 3

    Verify authority and assess the hardware

    Before opening or changing anything, we confirm you are the owner, manager or authorized tenant. Then we inspect the lock, the door and the frame. Older downtown buildings may have worn rim locks or mortise cylinders, while newer suites often use commercial grade cylinders.

  4. 4

    Fix it with the least damage possible

    For lockouts we use non-destructive methods first. For rekeying, we change the pins so old keys stop working. If a lock is failing, worn out or compromised, we explain the options for repair or replacement before we proceed.

  5. 5

    Test, cut keys and review key control

    We test every lock and door, cut working keys, and talk through who should hold which keys. For multi-tenant or multi-employee sites, we can discuss master key systems or electronic access options.

What affects the price

  • The type of lock: a standard commercial cylinder, a mortise lock, a panic bar or a high-security cylinder all differ in parts and labor.
  • The number of doors and cylinders involved, since rekeying one office door is a different job than a whole building.
  • Whether the work is an emergency call-out at night or a scheduled visit during the day.
  • The condition of the door, frame and existing hardware, especially on older buildings where parts may be worn or hard to match.
  • Whether you want simple keyed locks, a master key system or electronic access control with credentials.
  • How many keys or credentials you need cut or programmed.

Why Covina chooses us

  • Operating since 1987, with owner David Shar leading the work, so there is real experience behind the service.
  • Fully mobile and available 24/7, which suits businesses that need help outside normal hours.
  • Familiarity with both older downtown-style hardware such as mortise and rim locks, and modern commercial cylinders and panic hardware.
  • We aim for non-destructive entry first, protecting storefront doors and frames from unnecessary damage.
  • We explain options and what drives the cost before work begins, rather than pushing the most expensive fix.
  • We check authorization before opening or rekeying a business, which protects you and your property.

Commercial Locksmith across Covina

Covina's commercial life is concentrated in a few distinct areas. Downtown Covina, centered on Citrus Ave near Heritage Plaza and the Covina Center for the Performing Arts, has 1920s and 1930s buildings with small shops, offices and restaurants. Their doors can carry older mortise and rim hardware that is worth rekeying or upgrading rather than ignoring. A lockout or rekey at a business near the theater is a typical call for us, and ZIP code 91723 covers much of this central area.

Heading east, Charter Oak (91724) mixes neighborhood retail, offices and service businesses with residential streets. Businesses along Grand Ave, Badillo St and San Bernardino Rd often need rekeying after a staff change, a new lease or a break-in attempt. To the south, Covina Hills and the surrounding area (including ZIP 91722) have professional offices and small businesses that benefit from access control and better key management.

Commuters and employees moving through the Covina Metrolink station on the San Bernardino Line, and traffic along Interstate 10, mean many owners open early or close late. That is one reason round-the-clock mobile service matters here. If a lock fails at the start or end of your day, call (323) 997-8867 and we will come to you.

Can you rekey the locks after an employee leaves?

Do you have a shop I can visit?
No. We are a mobile-only business. A technician comes to your location with the tools needed to do the work on site.
Can you install access control or master key systems?
We can discuss master key systems and electronic access options for offices and multi-tenant sites. The right choice depends on your doors, staff and budget.
How much does a commercial lockout cost?
It depends on the lock type, door condition, time of day and the work needed, so we do not quote without details. Call (323) 997-8867 and we will explain what affects the price.

We try non-destructive methods first. If a lock is damaged or high-security, we explain the options before doing anything that could affect the door.
