A business lock problem rarely waits for a convenient time. A shop owner on Bonita Ave can't open for the morning rush, a manager finds a back door that no longer latches, or a former employee still holds a key. Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and our owner and lead tech, David Shar, built the business on practical, honest commercial work like this.
San Dimas is a mix of building types. The western-themed downtown has small retail and civic buildings with older storefront doors, while the semi-rural edges near San Dimas Canyon and Bonelli Park have barns, outbuildings, work yards and gated drives secured with padlocks and chains. Each calls for different hardware and a different approach, and we plan the visit around what your property actually uses.
We are fully mobile. There is no storefront to visit; a technician drives to your location with the tools and common hardware needed to work on site. We are available 24/7, so after-hours lockouts, break-in repairs and urgent rekeys can be handled when they happen, not when a shop opens.
How it works in San Dimas
- 1
Call and describe the situation
Phone (323) 997-8867 and tell us what happened: a lockout, a damaged door, a lost key, or an upgrade you're planning. Tell us the type of door and lock if you know it, and whether it's a storefront, office suite, warehouse or gated yard. That helps us bring the right equipment.
- 2
Confirm who is authorized
Before we open or change anything, we need to be sure the person asking has the right to authorize it, such as the owner, manager or property representative. This protects you and your tenants, especially in shared or leased buildings.
- 3
Assess the hardware on site
Your technician looks at the doors, cylinders, deadbolts, panic hardware, padlocks or gates involved. We explain what can be repaired, what should be rekeyed, and what really needs replacing, so you can choose without pressure.
- 4
Do the work with minimal damage
For lockouts we aim to open the door without harming it. For rekeying, we change the internal pins so old keys stop working and the existing hardware stays in place. If a lock must be replaced, we fit and adjust it so it operates smoothly.
- 5
Test and hand over keys
We test every lock and key before leaving, confirm doors close and latch properly, and give you the new keys. If you need a key plan for several staff, we can discuss how to organize it.

What affects the price
- The type of job: a simple lockout, a rekey, a hardware replacement or a larger access control installation each involve different labor and materials.
- The hardware involved: standard cylinders, high-security cylinders, panic bars, and commercial-grade deadbolts vary in cost and installation effort.
- The number of doors or locks: rekeying one office door differs from rekeying every door in a warehouse or multi-suite building.
- Time of day: urgent after-hours, weekend or holiday calls can be priced differently from scheduled daytime work.
- Site conditions: reaching a gated drive, outbuilding or large property near the canyon may affect the job, as can damaged doors or frames that need repair.
- Scheduled versus emergency work: planned upgrades let us order matching hardware ahead, while emergencies often require using what we can bring right away.

Commercial Locksmith across San Dimas
San Dimas businesses sit in some distinct settings. In Downtown / Old Town San Dimas, the western-facade buildings along Bonita Ave hold small shops, restaurants and civic offices, many with older storefront doors and shared entries. A lockout there at closing time or before opening is a common call, and we aim to get you back in without damaging the character of the entrance. Much of the area falls in ZIP code 91773.
Farther out toward San Dimas Canyon and Frank G. Bonelli Regional Park, the properties change. Larger rural lots, horse-keeping zones, barns, outbuildings and gated drives often rely on padlocks, chains and hasps that weather and wear. We service these locks, rekey padlocks and gate hardware, and help equestrian or small-business owners keep tack rooms and equipment storage secure. The Via Verde planned community on the southern hills uses HOA-standard hardware, and we can help with business-related or home-office rekeys there as well.
Whether you're near Arrow Hwy, San Dimas Ave or Foothill Blvd, or just off the 210, 57 or 10 freeways, our mobile service comes to you. Landmarks like Puddingstone Reservoir and Raging Waters Los Angeles draw seasonal traffic to the area, and nearby businesses sometimes need lock help outside normal hours. We're available around the clock at (323) 997-8867.
