A transponder key looks like an ordinary key, but the plastic head holds a small chip that talks to your vehicle's immobilizer. If the car doesn't recognize the chip, the engine won't start even when the blade turns the ignition perfectly. That is why a copy cut at a hardware counter often opens the door but won't run the car. It has to be programmed, not just cut.

In Fillmore this comes up in a few familiar ways. A spare key goes missing on a day trip along the Santa Clara River. A work truck needs an extra key for a second driver. A family finds that the only key they own has gone through the wash one too many times. In each case the car is usually sitting in a driveway or parking spot, and moving it is a hassle, particularly in a town where the nearest big dealerships are a drive away on SR-126.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, led by owner David Shar. We are fully mobile. There is no storefront to visit, and no need to tow a car to us. We bring the work to you at any hour, and we will explain what your particular vehicle needs before any work begins.

How it works in Fillmore

  1. 1

    Call and describe the vehicle

    Phone (323) 997-8867 and tell us the make, model, and year, and whether you still have a working key. This tells us whether you need a simple added key or a full replacement after all keys are lost.

  2. 2

    We travel to your location

    Because we are fully mobile and available 24/7, we meet you at your home, workplace, or wherever the car is stuck. We do not ask you to tow it anywhere.

  3. 3

    Confirm ownership

    Before creating a key for a vehicle, we ask for reasonable proof that you own it or are authorized to use it, such as registration and a matching ID. This protects you and every other owner.

  4. 4

    Cut and prepare the key

    If you need a new blade, we cut it to match your vehicle's lock. We then check that the key turns the door and ignition smoothly before moving to programming.

  5. 5

    Program the transponder to the immobilizer

    We connect to the vehicle and register the new chip so the immobilizer accepts it. Depending on the model, this may involve adding the new key alongside existing ones or resetting the stored key list.

  6. 6

    Test everything

    We start the engine, test the locks and any remote functions, and confirm all of your keys work before we finish. You leave with working keys, not a guess.

What affects the price

  • Whether you have a working key to copy or all keys are lost, since a no-key situation generally takes more work.
  • The vehicle's make, model, and year, because immobilizer systems differ widely between manufacturers.
  • The type of key: a basic chip key, a remote-head key, or a smart or push-button fob each involve different parts and procedures.
  • How many keys you need programmed in a single visit.
  • Whether the key blade also needs to be cut or the ignition or lock needs repair.
  • The time of day and how far we travel to reach you.

  • Serving the area since 1987, with owner David Shar leading the work.

  • We test every key, including door, ignition, and remote functions, before we leave.

Transponder Key Programming across Fillmore

Fillmore is a small citrus and railroad town, and cars here live in all sorts of places: driveways off A St and Mountain View St in North Fillmore, curbs along Central Avenue near the Fillmore & Western Railway, and farm lots out in Bardsdale across the Santa Clara River. Because we come to you, it doesn't matter whether your vehicle is in Downtown Fillmore, Cordova Park, or on a rural property in ZIP code 93015 or 93016.

Many residents drive daily on SR-126 (Ventura St) or SR-23 (Grimes Canyon Rd), and a dead key fob or lost key can strand you far from a dealer. If a work truck is parked at a ranch near Old Telegraph Rd or you are visiting the Fillmore Fish Hatchery or Rancho Camulos Museum and discover your key is gone, we can come to the vehicle and program a replacement on the spot.

Fillmore also has a lot of work vehicles and farm pickups, where extra keys for employees or family members are a practical need. If you need a spare programmed before a key goes missing, that is usually simpler than starting over from nothing. Call (323) 997-8867 any time and we will talk through your vehicle.

Transponder Key Programming in Fillmore — FAQs

Can you program a transponder key at my car in Fillmore?
Yes. We are fully mobile and come to your vehicle, whether it is in Downtown Fillmore, North Fillmore, Bardsdale, or elsewhere. Call (323) 997-8867 to get started.
Do I need to tow my car to you?
No. We have no storefront, and programming is done on site at your vehicle, so towing is typically not needed.
What if I have lost all my keys?
We can often create a new key from scratch for many vehicles. It generally involves more work than copying an existing key, so call (323) 997-8867 with your vehicle details and we will explain what is possible.
Why won't a hardware store copy start my car?
A cut key may turn the lock, but without a programmed chip the immobilizer will not allow the engine to start. The chip must be registered to your vehicle.
Are you available at night or on weekends?
Yes, we are available 24/7. We make no promises about specific arrival times, but you can call (323) 997-8867 at any hour.
What do you need from me to program a key?
We ask for proof of ownership or authorization, such as registration and a matching photo ID, before making keys for a vehicle.
How is the price determined?
It depends on the vehicle, key type, whether you have an existing key, the number of keys, and location. We explain these factors before starting work.
Can you program spare keys for a work truck or farm vehicle?
Yes. Many Fillmore households and ranches keep spares for extra drivers, and we can program additional keys during one visit.
