Losing a key fob in Claremont tends to happen at inconvenient moments: after an evening class on campus, after dinner near Yale Avenue, or at the trailhead of Claremont Hills Wilderness Park. A modern fob is more than a key. It holds a transponder chip, a remote transmitter, and in many newer cars a proximity credential that the vehicle has to recognize before it will start. When one is lost, cracked, or dead, you need someone who can cut, pair, and program a replacement on the spot.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and owner David Shar leads our work. We are fully mobile. There is no storefront to visit and no tow to a shop. We bring the equipment to wherever the vehicle is parked, which in Claremont might be a residential street lined with old shade trees, a campus lot, or a driveway in the hills.

We replace and program remote key fobs and smart or proximity keys. That includes the situation where you have lost every key and the car has no working spare, which is usually the most stressful case but is routinely solvable. We are happy to talk through your vehicle and what is involved before we head out.

How it works in Claremont

  1. 1

    You call and describe the situation

    Call (323) 997-8867 any hour. Tell us the make, model, and year of the vehicle, whether you have any working key left, and where the car is parked. That helps us bring the right blanks, fobs, and programming tools.

  2. 2

    We confirm ownership

    Before making a new key for a vehicle, we verify that you are the owner or authorized user. Expect to show identification and registration or other proof tied to the car. This protects you and is standard practice for responsible locksmiths.

  3. 3

    We come to your vehicle

    Because we are fully mobile, we travel to you in Claremont, whether that is a driveway in North Claremont, a street near the Village, or a lot at one of the colleges. The work happens beside your car.

  4. 4

    Cut and prepare the key or fob

    If your vehicle uses a physical emergency blade, we cut it to match the lock. We then prepare the replacement fob so its transponder and remote functions can be paired with your car's computer.

  5. 5

    Program and pair with the vehicle

    We connect programming equipment to the car and register the new fob so it starts the engine and operates remote functions like lock, unlock, and trunk release. On proximity systems we also confirm push-button start recognizes the key.

  6. 6

    Test everything before we leave

    We test the remote buttons, the ignition or push-start, and the emergency blade in the door. If you want the old or spare fobs checked as well, we can confirm they still work.

What affects the price

  • Vehicle make, model, and year, since some brands use far more complex security systems than others.
  • Type of key: a basic remote head key, a flip key, or a smart proximity fob all involve different hardware and programming steps.
  • Whether you still have a working key to copy from or have lost all keys, which changes how much programming work is needed.
  • Whether the fob is an original-equipment part or a quality aftermarket unit, where both are available for your vehicle.
  • Whether an emergency blade must be cut or a worn lock needs attention.
  • Time of day and the vehicle's location, since we serve you around the clock and travel to you.

Why Claremont chooses us

  • Fully mobile service with no storefront, so the programming happens at your car instead of requiring a tow.
  • In business since 1987, with David Shar as owner and lead technician.
  • Available 24/7, including nights and weekends, for lost fobs that leave you stranded.
  • We handle all-keys-lost situations, not just duplicates from an existing key.
  • We verify ownership before programming, which protects you from unauthorized key making.
  • We explain your options in plain language, including when a replacement fob and when a simple battery or repair makes more sense.

Key Fob Replacement across Claremont

Claremont is an education-centered city on the eastern edge of Los Angeles County, and the way people park and drive here shapes the calls we get. Around The Claremont Colleges, including Pomona, Harvey Mudd, Scripps, Claremont McKenna, and Pitzer, students, faculty, and visitors leave cars in campus lots and on surrounding streets, and a lost fob can strand someone far from home. In Claremont Village along Yale Avenue, diners and shoppers sometimes drop a fob between a restaurant and a parking space, or discover a dead battery after an evening out.

Residents in the older neighborhoods around the Village, with their Craftsman bungalows and tree-lined streets, often park on the street or in narrow driveways, and we work comfortably in those settings. Farther north, North Claremont and the hillside Claraboya area have newer homes and steeper driveways, and many drivers commute out via Foothill Boulevard, Indian Hill Boulevard, or onto SR-210 and Interstate 10. If your fob fails before a commute, we can come to your home in ZIP code 91711.

We also hear from people who spent the day at California Botanic Garden or hiking in Claremont Hills Wilderness Park and came back to find a key missing. Wherever you are in Claremont, call (323) 997-8867 and we will talk through your vehicle and get a replacement fob programmed on site.

Key Fob Replacement in Claremont — FAQs

Can you replace a key fob if I've lost all my keys?
Yes. All-keys-lost situations are something we handle regularly. We verify ownership, then cut and program a new key or fob to your vehicle on site. Call (323) 997-8867 and tell us the make, model, and year.
Do I need to tow my car to you?
No. We are fully mobile and there is no storefront. We come to your vehicle anywhere in Claremont, whether that's near Yale Avenue, on a college campus, or at your home.
Are you available at night or on weekends?
Yes, we operate 24/7. If you lose a fob after an evening in Claremont Village or late on a weekend, call (323) 997-8867 any time.
What proof of ownership will I need?
We typically ask for photo ID along with registration, title, or other documentation connecting you to the vehicle. This is a normal safeguard that keeps your car secure.
How is the cost of a replacement fob determined?
It depends on factors such as your vehicle's make and year, the type of fob or smart key, whether you have a working key already, and whether the part is original or aftermarket. We can discuss these when you call.
Will my old lost fob still work after you program a new one?
In many vehicles, programming can be set up so that lost fobs are removed from the car's memory, which helps prevent someone else from using it. Whether this is possible depends on the vehicle, and we can explain it for yours.
My fob just stopped working. Do I need a new one?
Not always. A dead battery or a worn button is common. We can check whether the fob needs a battery, repair, or full replacement before you commit to anything.
Can you program a fob I bought online?
Often we can, depending on whether the fob is compatible with your vehicle and in good condition. Contact us at (323) 997-8867 with your vehicle details and the fob's part information so we can tell you what to expect.
