A car problem rarely picks a convenient place. In San Dimas it might happen in the lot at Frank G. Bonelli Regional Park after a long afternoon by the water, on a dirt shoulder near a horse property off San Dimas Canyon Road, or curbside on Bonita Ave after dinner downtown. Our automotive locksmith service is fully mobile, so the work happens right where the vehicle is sitting. There is no shop to tow it to and no storefront to visit.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and owner and lead technician David Shar built the business on the idea that a locksmith should be honest about what a job really needs. That matters with cars, because the range of problems is wide. A simple lockout is a very different job from a lost-all-keys situation on a late-model vehicle with an immobilizer and a push-button start.

We work on cars, trucks, motorcycles, RVs and fleet vehicles. San Dimas has plenty of all of them: commuter sedans heading for the 210 or the 57, pickups that tow horse trailers, RVs parked beside ranch-style homes, and small business vehicles that work around the Foothill corridor. Whatever you drive, call (323) 997-8867 and we will talk through what is happening before anyone heads your way.

How it works in San Dimas

  1. 1

    You call and describe the vehicle

    Phone (323) 997-8867 at any hour. Tell us the make, model, approximate year, what happened, and exactly where the vehicle is. Details like whether the key is inside, lost, or broken in the lock help us arrive prepared with the right tools and key blanks.

  2. 2

    We confirm the scope before work starts

    We explain what the job involves and which factors will shape the price, so there are no surprises. If your situation turns out to be simpler or more complex than it sounded on the phone, we tell you before we begin.

  3. 3

    We verify ownership

    Before opening a vehicle or cutting a key, we ask for reasonable proof that the car is yours, such as ID and registration or insurance paperwork. It protects you, and it is a standard part of working responsibly in this trade.

  4. 4

    We do the work on site

    For lockouts we use methods designed to avoid damaging paint, weatherstripping or door mechanisms. For lost keys or fobs, we cut and program replacements at your vehicle, whether it is in a driveway, a parking lot or on a quiet road.

  5. 5

    We test everything and hand it over

    Once the door is open or the new key is made, we test it: locking, unlocking, starting the engine, and the remote functions where applicable. You leave with keys that work, and we answer any questions about spare keys.

What affects the price

  • Vehicle make, model and year, since newer cars with immobilizers and encrypted keys need more programming than older mechanical-key vehicles.
  • The type of key involved: a basic cut key, a transponder key, a remote head key, a smart key or a push-button-start fob each involve different parts and procedures.
  • Whether you have a working key to copy or all keys are lost, because originating a key from scratch takes more steps than duplicating one.
  • The nature of the problem, such as a simple lockout, a broken key in a door or ignition, or a damaged ignition cylinder that needs repair.
  • Time of day and location of the vehicle, since a late-night call to a remote spot differs from a daytime call to an easy-access lot.
  • Vehicle type, as motorcycles, RVs and commercial fleet vehicles can use different lock systems and may require different tools or multiple keys.

Why San Dimas chooses us

  • Fully mobile since 1987, with 24/7 availability, so the work comes to your vehicle instead of the vehicle going to a shop.
  • One locksmith business that handles cars, trucks, motorcycles, RVs and fleets, so a single call covers a household with a mix of vehicles.
  • Honest scoping: we explain what is needed and what is not, rather than pushing a replacement when a repair or simple entry will do.
  • Residential and automotive under one roof, which helps in San Dimas where a call about a barn gate may be followed by one about the truck parked beside it.
  • Owner involvement: David Shar leads the technical work, so standards come from someone with decades in the trade.
  • Careful entry methods that aim to protect your paint, seals and door electronics rather than rushing the job.

Automotive Locksmith across San Dimas

San Dimas has a mix of driving habits that shapes the calls we get. In the Via Verde hillside community in ZIP code 91773, residents commute down toward Arrow Hwy and the 210 or 57 freeways, and cars sit in garages and HOA-managed driveways where a misplaced fob can turn into a morning problem. If you recently bought a home there and are sorting out vehicles and household locks together, we can address both in one visit.

Near San Dimas Canyon and the larger lots around Bonelli Park, trucks and trailers are part of daily life. Horse-keeping properties often have gated drives, barns with padlocks, and work vehicles parked well off the pavement. A mobile locksmith matters here: a tow truck is a poor answer when the truck is on a ranch lot, and we can handle the vehicle and, if needed, the gate or barn padlock during the same trip.

Downtown or Old Town San Dimas, with its western-style facades along Bonita Ave, brings a different pattern: visitors and shop owners who lock keys in a car while parking near Bonita Ave and San Dimas Ave, or fleet vehicles tied to small local businesses. Day-trippers heading to Puddingstone Reservoir or Raging Waters Los Angeles sometimes call after a long day when keys end up in a bag locked in the trunk. Wherever in 91773 you are, call (323) 997-8867.
