A modern car key is more than a cut piece of metal. Inside the plastic head is a small transponder chip that talks to the vehicle's immobilizer, and if the car does not recognize that chip, the engine will not start no matter how perfectly the blade turns the ignition. Transponder key programming is the work of teaching the car to accept a new or replacement key, and it is what we do for Agoura Hills drivers who have lost their only key, cracked a worn fob, or simply want a spare before the next problem hits.

Our business is fully mobile, and that matters for this work. There is no shop to tow your car to and no counter to visit. We drive to you, whether the car is parked in a driveway in Morrison Ranch, sitting in a lot off Agoura Road, or stranded near a US-101 on-ramp. Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and owner David Shar has seen the technology change from basic chipped keys to the push-button systems common today.

Because Agoura Hills is a commuter-heavy, spread-out city, with households that often run two or three vehicles and drive the 101 daily, a dead or missing key can disrupt a whole family's schedule. Having a technician arrive where the car already is, at any hour, solves that without the cost and hassle of a dealership trip. Call (323) 997-8867 and we will talk through your vehicle and your situation.

How it works in Agoura Hills

  1. 1

    Tell us about the vehicle

    When you call (323) 997-8867, we ask for the make, model, and year, and whether you still have a working key. This tells us whether you need a simple duplicate, a full all-keys-lost replacement, or a different type of key, such as a fob or smart key.

  2. 2

    We drive to your location

    We are 24/7 and mobile, so we come to wherever the car is, be it a home driveway, a retail parking lot, or the roadside. Nothing needs to be towed.

  3. 3

    Confirm ownership

    Before we create a key for any vehicle, we verify that you are the owner or authorized user. This protects you and is standard practice for responsible locksmiths.

  4. 4

    Cut the key and prepare the chip

    We cut the blade to match your vehicle's lock, using the door or ignition lock when no working key is available, and we select a transponder chip compatible with your car's system.

  5. 5

    Program to the immobilizer

    Using professional diagnostic and programming equipment, we pair the new key with the vehicle's immobilizer. If other keys are present, we can add the new one without disturbing them.

  6. 6

    Test everything before we leave

    We check that the key turns the ignition, starts the engine, and operates any remote buttons. We also make sure every key you have still works, then hand everything over to you.

What affects the price

  • Vehicle make, model, and year, since some manufacturers use more complex immobilizer systems than others.
  • Key type: a basic transponder key, a remote-head key, a flip key, and a push-button smart key each involve different parts and procedures.
  • Whether you have a working key already or have lost all keys, as all-keys-lost situations take more steps.
  • Whether the vehicle needs a blade cut from scratch or a key cut to an existing code.
  • The number of keys you want programmed in one visit, since adding a spare while we are on site is usually more efficient than a second trip.
  • Time of day and location, because after-hours and out-of-the-way calls can affect the overall quote.

Why Agoura Hills chooses us

  • Fully mobile, so your car stays put and you avoid a tow to a dealership.
  • Available 24/7, including nights and weekends, when lost keys always seem to happen.
  • In business since 1987, with owner David Shar leading the work.
  • We are upfront about what affects the quote, and we talk through options by phone before we head out.
  • We verify ownership before programming, which keeps your vehicle secure.
  • We test every key, including remote functions, before we leave, and we encourage a spare so you do not end up stranded again.

Transponder Key Programming across Agoura Hills

Agoura Hills has a distinctive mix of places where key trouble tends to strike. In Old Agoura, the semi-rural equestrian area with horse properties and gated ranch homes, trucks and SUVs that haul trailers often have keys that are thrown into barn pockets, dropped in arenas, or left on fence posts. A lost chip key out there is a real headache, and we can come to the property rather than have you find a ride to town. In the planned communities of Morrison Ranch and around Lake Lindero, many households park in driveways and carports, so mobile service on-site is convenient and discreet.

Commuters here live on the US-101 Ventura Freeway, Kanan Road, and Agoura Road, and the car is often the lifeline between home, work, and the weekend trip to Paramount Ranch or Chumash Park. If a key fails in a lot at Whizin's Market Square or along the aluminum-storefront retail strips on Agoura Road, we can meet you there. Residents in ZIP codes 91301 and 91376 can reach us at (323) 997-8867 any hour.

If you are in the shadow of Ladyface Mountain or in the hillside custom homes toward Malibu Canyon, steep and winding driveways do not stop a mobile service. We can program the key right where the car sits. And since transponder keys are often the first thing to wear out on a car that has been driven daily for years, it is smart to add a spare before the original gives out.

Transponder Key Programming in Agoura Hills — FAQs

What is a transponder key?
It is a key with a small chip inside the head that sends a code to your car's immobilizer. If the code does not match, the engine will not start, even if the blade turns the ignition. Programming pairs that chip with your vehicle.
Can you program a key if I have lost all of my keys in Agoura Hills?
In many cases, yes. All-keys-lost situations take more steps than adding a spare, but we can generally cut and program a new key on-site. Call (323) 997-8867 with your vehicle details and we will tell you what to expect.
Do I need to tow my car to you?
No. We are fully mobile and have no storefront. We come to the car, whether it is at home in Morrison Ranch, at a parking lot off Kanan Road, or elsewhere in the city.
Are you available at night or on weekends?
Yes. Crenshaw Lock Company is available 24/7. Call (323) 997-8867 at any hour and we will talk through your situation.
Why not just go to the dealership?
Dealerships can do this work, but you may need to have the car towed there and wait for an appointment. A mobile locksmith comes to you, which saves time and often simplifies the process.
Do I need to prove I own the vehicle?
Yes. We verify ownership or authorization before creating a key for any vehicle. This protects you from theft and is a normal part of responsible locksmith work.
Can you add a spare key when I still have a working one?
Yes, and it is usually the easier and more economical situation. Adding a spare before you lose your only key avoids the extra steps of an all-keys-lost job.
Can you program push-button or smart keys too?
We handle many types of keys, including remote-head and smart keys, depending on the vehicle. Because support varies by make and model, call (323) 997-8867 with your year, make, and model and we will confirm.
