A key fob that stops working, or disappears, rarely picks a convenient moment. In La Verne it might happen in a parking space off D Street after dinner, in a driveway in North La Verne with the foothills getting dark, or in a campus lot at the University of La Verne when you are due in class. Crenshaw Lock Company is fully mobile, so we bring the equipment to wherever the car is sitting. There is no storefront to get to, and you do not need to tow a car you cannot start.

Key fob replacement covers more than one situation. Some people have lost every key and need a new fob created from scratch. Others still have a working spare and just want another one before the last one goes missing. Some have a fob that is cracked, water damaged, or has a dead button, and some drive a vehicle with a smart or proximity key that simply will not communicate with the car anymore. Each case calls for slightly different handling, and we start by asking the right questions about your make, model, and year.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and owner and lead technician David Shar built the business on straightforward service. We tell you what the job involves, what affects the cost, and whether a replacement is really needed or a simpler fix, like a battery or a re-sync, will do. Call (323) 997-8867 any time of day or night and we will take it from there.

How it works in La Verne

  1. 1

    Call and describe the situation

    Phone (323) 997-8867 and tell us the make, model, and year of the vehicle, and whether you have any working key at all. Let us know where the car is parked in La Verne so we can plan the visit. We are available around the clock.

  2. 2

    Confirm the key type

    Fobs vary a great deal. Some are a basic remote paired with a separate metal key, some have a flip key, and others are smart keys that let you start the car with a push button. Identifying which one your vehicle uses guides every later step.

  3. 3

    Verify ownership

    Before we create a new key for a vehicle, we need to be reasonably sure you are authorized to have it. Expect to be asked for identification and proof that the car is yours. This protects you as much as anyone.

  4. 4

    Cut and prepare the key

    If your fob includes a mechanical blade, we cut it on site. We then prepare the new fob so it can be recognized by your car's immobilizer system.

  5. 5

    Program the fob to the vehicle

    Using professional programming equipment, we pair the new fob with the car so the remote functions and engine start work as intended. When it applies, we can also remove lost keys from the system so they no longer operate the vehicle.

  6. 6

    Test everything before we leave

    We check lock, unlock, trunk, panic, and starting, and test the mechanical key in the door. You should leave with a fob you have seen working, not just one we hope works.

What affects the price

  • Vehicle make, model, and year, since some brands use far more complex security systems than others.
  • Type of fob: a basic remote, a flip key, or a smart proximity key all involve different parts and programming work.
  • Whether you have a working key to copy or all keys are lost, which changes how much of the process is needed.
  • Whether the key blade needs cutting and whether the fob is a factory original or an aftermarket-compatible part.
  • Time of day and the location of the vehicle, since we are on call 24/7 and travel to you.
  • Whether old or lost fobs need to be erased from the car's memory as part of the job.

Why La Verne chooses us

  • Fully mobile service: we work at your car in the driveway, street, or campus lot, so nothing needs to be towed.
  • In business since 1987, with owner David Shar leading the technical work.
  • Available 24/7, including nights and weekends, which matters when a fob fails after hours.
  • Honest diagnosis: if the problem is a weak battery or a simple re-sync, we will say so instead of selling a new fob.
  • Clear explanation of what affects cost before work starts, with no vague add-ons.
  • Ownership checks that protect you from someone else creating keys for your vehicle.

Key Fob Replacement across La Verne

La Verne has a mix of settings where fob problems tend to show up. In Old Town La Verne, around D Street and Bonita Ave, street parking and dinner outings mean a lost or failed fob often happens away from home. Many of the nearby early-1900s Craftsman homes also have older driveways and detached garages where cars are parked for long stretches, so a dead battery in a rarely used spare is a common surprise. If you are in ZIP code 91750, we can come to you wherever the vehicle is.

Near the University of La Verne, students and staff rely on their cars for commuting along Foothill Blvd, Arrow Hwy, and Wheeler Ave. Student rentals mean keys change hands, get shared, and get lost, and a misplaced fob at the start of a term is an easy problem to have. Up in North La Verne and toward Marshall Canyon Regional Park, newer foothill developments often have vehicles with smart keys, and a fob that goes missing after a hike or a trailhead stop can leave you far from a dealer.

Drivers who commute on the SR-210 or SR-57, visit Fairplex in neighboring Pomona, or work around Brackett Field also find themselves stranded in lots and garages far from home. Because we are mobile, we meet you at the vehicle. Call (323) 997-8867 and tell us where you are.

Key Fob Replacement in La Verne — FAQs

Can you replace a key fob if I have lost all my keys in La Verne?
In many cases, yes. With all keys lost, we create a new key and program it to the car on site after verifying ownership. Call (323) 997-8867 with your vehicle details and we will explain what your car requires.
Do I need to tow my car to you?
No. Crenshaw Lock Company is fully mobile, so we come to your vehicle anywhere in La Verne, whether that is Old Town, a campus lot, or a foothill driveway.
Is it cheaper than going to the dealer?
We cannot promise that for every vehicle, because pricing depends on make, model, and key type. What we can say is that you avoid towing and a trip to a dealership, and we will explain the cost factors up front.
Can you program a smart or push-button key?
Many smart and proximity keys can be programmed by a mobile locksmith, though some vehicles are more restrictive than others. Call (323) 997-8867 with your make, model, and year and we will tell you what to expect.
What proof of ownership do I need?
Typically a government-issued ID and documents showing the vehicle is yours, such as registration or title. This step protects you from unauthorized key creation.
My fob works sometimes. Do I need a new one?
Not necessarily. A weak battery, worn buttons, or a lost sync can cause intermittent behavior. We check these first and recommend replacement only if it is actually needed.
Can you erase the old lost fob from my car?
Often yes. When the vehicle supports it, we can clear old keys from the system during programming so a lost fob no longer operates the car.
Do you work late at night or on weekends?
Yes. We are available 24/7. Call (323) 997-8867 at any hour and we will talk through your situation.
