Losing a key fob in San Dimas is more than an inconvenience. Many of us drive the Foothill Freeway, the 57, or Arrow Highway every day, and a car that will not recognize its key can derail a whole schedule. Whether the fob fell out of a pocket at Bonelli Park, got soaked near Puddingstone Reservoir, or simply stopped responding, there is usually a way to get you moving again without a tow.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and owner and lead technician David Shar built the business around coming to the customer. We are fully mobile. There is no storefront to visit, so the work happens in your driveway, your office lot, or wherever the vehicle is parked.

Key fob replacement covers several situations: a single lost fob, a broken or worn-out remote, a smart key that no longer pairs, or a car where every key has gone missing. Each one calls for a slightly different approach, and we will tell you plainly what your vehicle needs before any work starts.

How it works in San Dimas

  1. 1

    Call and describe the situation

    Phone (323) 997-8867 and tell us the make, model, and year, plus whether you have any working key left. Let us know where the car is parked, whether that is a Via Verde driveway, a lot on Bonita Ave, or a trailhead near San Dimas Canyon.

  2. 2

    We come to the vehicle

    Because we are mobile and available 24/7, a technician travels to you. Having the car on site matters, since programming happens through the vehicle itself.

  3. 3

    Verify ownership

    Before cutting or programming anything, we confirm you are the rightful owner using identification and registration or similar documentation. This protects you as much as it protects us.

  4. 4

    Cut and prepare the new fob

    If your fob has an emergency or blade key, we cut it to code. We then match the correct fob or smart key to your vehicle's system and frequency.

  5. 5

    Program and test

    We pair the new fob to the vehicle's computer, then test locking, unlocking, trunk, panic, and push-to-start functions where equipped. Any other fobs you own can be re-paired at the same visit.

  6. 6

    Review spares and next steps

    We talk through whether a spare makes sense, how to care for the battery, and what to do if a key goes missing again.

What affects the price

  • Vehicle make, model, and year, since some systems are far more involved to program than others.
  • Type of key: a basic remote, a flip key, or a proximity smart key with push-button start.
  • Whether you still have a working key or all keys are lost, which changes the programming process.
  • Number of fobs needed, including whether you want a spare made during the same visit.
  • Time and location of the call, including after-hours service and how far the technician travels.
  • Whether the fob needs a cut emergency blade in addition to electronic programming.

Why San Dimas chooses us

  • Fully mobile service means programming is done at your car, not at a shop you must tow to.
  • Operating since 1987 under owner and lead tech David Shar, so the work comes from long hands-on experience.
  • 24/7 availability for the late-night and weekend problems fobs tend to cause.
  • We explain what is needed and what drives the cost before work begins, with no pressure to add extras.
  • We handle the full job: key cutting, fob programming, and testing in a single visit where possible.
  • Familiar with San Dimas properties, from hillside HOA homes to equestrian lots, so we know how and where people actually park.

Key Fob Replacement across San Dimas

San Dimas has a mix of settings that shapes how fob problems happen. In the Via Verde hillside community, residents often park in garages and driveways on sloped streets, and a dead fob battery or a lost remote after a move is a common reason for a call. Down in Downtown and Old Town San Dimas, business owners and employees along Bonita Ave sometimes lose a fob among the western-style storefronts or during an event, and we can meet you right at the curb.

Out toward San Dimas Canyon and Bonelli Park, the properties get larger and more rural. Ranch-style homes from the 1960s and 70s, horse-keeping lots, barns, and gated drives mean keys, fobs, and padlocks often get misplaced together. We can replace a vehicle fob and, if needed, discuss gate or barn hardware at the same visit.

We serve ZIP code 91773 and the surrounding area, including drivers who commute along the 210, the 57, Foothill Blvd, and San Dimas Ave. Families heading to Raging Waters or Puddingstone Reservoir also call when a fob goes missing in a parking lot. Wherever you are in San Dimas, call (323) 997-8867.

Key Fob Replacement in San Dimas — FAQs

Can you replace a key fob if I lost every key to my car?
In many cases, yes. An all-keys-lost situation takes more steps, but a mobile technician can often cut and program a new key or fob at your vehicle. Call (323) 997-8867 with your vehicle details and we will explain what is possible.
Do I need to tow my car to a dealership in San Dimas?
Often not. Because we are fully mobile, we bring the equipment to your car, whether it is at home in Via Verde or in a lot off Arrow Hwy. Some specific vehicles may have special requirements, and we will tell you up front.
Is my fob just dead, or does it need replacing?
Sometimes a fresh battery solves it. If the fob still fails, it may have lost pairing or have internal damage. We can check it and tell you which it is before recommending a replacement.
What is the difference between a remote fob and a smart key?
A remote fob typically needs a button press and often has a metal blade. A smart or proximity key lets you unlock and start the car while it stays in your pocket. Smart keys usually involve more complex programming.
Do you offer service at night or on weekends?
Yes. We are available 24/7. Call (323) 997-8867 any time and we will arrange a visit to your location.
What do I need to show to get a new fob?
You will need to prove ownership, typically with a photo ID and vehicle registration or comparable documentation. This is a standard safeguard against theft.
Can you make a spare while you are here?
Yes, and it is usually easier to add a spare during the same visit than to start over later after losing the only key. Ask about it when you call.
What affects the cost of replacing a fob?
The main factors are vehicle make and year, the type of key, whether you have a working key, how many fobs you want, and the time and location of service. We explain these before starting.
