A transponder key looks like an ordinary key, but inside the plastic head is a small chip that talks to your vehicle's immobilizer. If the chip's code isn't recognized, the engine won't start, even when the metal blade turns the ignition perfectly. That's why a hardware-store copy often fails to start the car. In Agua Dulce, where the nearest dealership can be a long drive down CA-14, losing your only key or watching a worn one finally die is more than an inconvenience.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and our work is entirely mobile. There is no storefront to visit. The equipment comes to you: key cutting, chip cloning and programming tools travel in our service vehicle, so a truck parked at a barn, a car left at a trailhead, or a vehicle stuck in a long gated driveway can all be handled where they sit.

We program replacement and spare keys for many makes and models, including situations where every key has been lost. Because Agua Dulce is spread across large parcels and canyon roads, we'd rather you call and describe where the vehicle is, what it is, and what keys you still have. That helps us plan the visit and bring the right blanks and tools.

How it works in Agua Dulce

  1. 1

    Call and describe the vehicle

    Phone (323) 997-8867 any hour. Tell us the make, model, year and where the vehicle is, plus whether you have a working key or have lost them all. Rural directions help, such as the cross street off Agua Dulce Canyon Rd or the gate details.

  2. 2

    We travel to you

    Our service vehicle comes to your location, whether it's a ranch driveway, a hangar lot at the Agua Dulce Airpark, or the shoulder of Sierra Highway. We don't ask you to tow the vehicle anywhere.

  3. 3

    Verify ownership

    Before creating or programming a key, we ask for proof that the vehicle is yours, typically ID and registration or title. It protects you and keeps keys out of the wrong hands.

  4. 4

    Cut the key blade

    If you need a new key cut, we make the blade to fit your locks. With keys lost, we can generate the cut from the vehicle's lock or its key code when available.

  5. 5

    Program the transponder

    We connect programming equipment to the vehicle and register the new chip with the immobilizer. Depending on the vehicle, we may also add a spare or remove lost keys from the system.

  6. 6

    Test everything

    We check that the key turns the ignition, starts the engine, and operates the door locks and any remote functions. You leave with working keys before we pack up.

What affects the price

  • Vehicle make, model and year, since some immobilizer systems are much more involved to program than others
  • Whether you have a working key to copy or all keys are lost, which changes the programming steps required
  • The type of key: a basic chip key, a remote-head key, a flip key or a push-button smart key
  • How many keys you need programmed, including a spare while we're already there
  • Your location and the distance of the drive, which can be a factor on remote Agua Dulce parcels
  • Time of day, since we work nights, weekends and holidays and after-hours calls may be priced differently

Why Agua Dulce chooses us

  • Fully mobile since 1987: we come to the vehicle, so there's no towing it to a shop
  • Available 24/7, which matters when a key fails at a trailhead or late at night
  • Experience with rural properties, including long driveways, gates and outbuildings where vehicles are often parked
  • Ownership verification on every job, so keys are only made for the rightful owner
  • Straight answers on what's needed before we arrive, with no invented promises about timing
  • The same team can handle related work on the property, such as a gate padlock or a shop rekey, in one visit

Transponder Key Programming across Agua Dulce

Agua Dulce is horse and ranch country, and vehicles here live a harder life than in the suburbs. Trucks and SUVs are parked at barns and tack rooms, left at the end of long gated driveways, or hauled out to Vasquez Rocks Natural Area Park and trailheads along the Pacific Crest Trail. A key can get lost in a pasture, soaked in a trough, or crushed in dust and heat, and a transponder chip doesn't always survive. We hear from people in the Agua Dulce townsite, Sweetwater and the surrounding canyon roads when that happens.

The Agua Dulce Airpark community adds its own situations. Residents there often keep a car or truck near the hangar, and a lost key can leave you stranded far from town. We come to the vehicle, whether that's in a hangar driveway or a ranch yard off Escondido Canyon Rd or Davenport Rd. We can also look at the property's other locks while we're out, such as a gate latch, a detached shop or a hangar door.

If you're in ZIP code 91390 and are stuck without a working key, call (323) 997-8867. Whether you're near the Agua Dulce Winery on Sierra Highway, just off CA-14, or deep in a canyon parcel, tell us where you are and we'll plan the trip.

Transponder Key Programming in Agua Dulce — FAQs

Can you program a transponder key at my ranch in Agua Dulce?
Yes. Our service is fully mobile, so we come to your driveway, barn area or wherever the vehicle is parked. Call (323) 997-8867 with your location and vehicle details.
I've lost all my keys. Can you still make a new one?
In many cases, yes. All-keys-lost situations take more steps than copying a working key, but we can often cut and program a new key on site. Call (323) 997-8867 to discuss your vehicle.
Why won't my copied key start the car?
The metal blade may fit, but if the chip inside hasn't been programmed to the immobilizer, the engine won't start. The chip must be registered with the vehicle's computer.
Do I need to prove the vehicle is mine?
Yes. We ask for ID and proof of ownership such as registration or title before making or programming keys. This protects owners from theft.
What affects the cost of transponder key programming?
The main factors are the vehicle's make, model and year, the type of key, whether you have a working key, how many keys you need, and your location and time of day. We don't quote prices on this page, so call (323) 997-8867 to talk through your situation.
Do you work nights and weekends?
Yes. We're available 24/7, including nights, weekends and holidays. Because we're mobile, we come to wherever the vehicle is.
Is it better to go to the dealer or use a mobile locksmith?
Dealers can program keys, but you'd typically need the vehicle brought to them. A mobile locksmith comes to you, which saves a tow or a long drive from Agua Dulce.
Can you add a spare key while you're there?
Usually yes. Adding a spare during the same visit is often easier than doing it after the last key is lost. Mention it when you call (323) 997-8867.
