A modern car key is more than cut metal. Inside the plastic head sits a small transponder chip that talks to the vehicle's immobilizer, and if the car does not recognize that chip, the engine will not run no matter how perfectly the blade turns in the ignition. Programming is the step that introduces a new key to the car. It is where many West Hills drivers get stuck, because a hardware store can duplicate the metal but cannot teach the car anything.

West Hills is a driving community. Families commute down Victory Blvd and Roscoe Blvd, run errands along Platt Ave and Fallbrook Ave, and head to the 101 for work. With that much daily use, it is common to lose a key at a trailhead near the Upper Las Virgenes Canyon Open Space Preserve, drop one in a parking lot, or discover that the only working key has a failing chip. Our service is fully mobile. There is no storefront to visit, so the work happens where your car is parked, whether that is a driveway, a hospital lot, or the side of the road.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and David Shar leads the work. We are available around the clock, and we will tell you plainly what your vehicle needs before we start. Some cars accept an added key easily. Others require a more involved process when every key has been lost. Knowing which situation you are in is the first and most important step.

How it works in West Hills

  1. 1

    Call and describe the vehicle

    Call (323) 997-8867 and tell us the make, model, and year, plus whether you still have a working key. That single detail, a spare in hand or none at all, shapes the whole job. We will also ask where the car is so we can come to you.

  2. 2

    Verify ownership

    Before we create a key that starts a vehicle, we ask for proof that the car is yours, such as registration and a matching photo ID. This protects you and protects the car. It is a standard part of responsible automotive locksmith work, and we do not skip it.

  3. 3

    Identify the correct chip and key type

    Vehicles use different transponder systems and different key blanks, including traditional cut keys, laser-cut keys, and remote head keys. We confirm exactly what your immobilizer expects so the new key is compatible rather than a near miss.

  4. 4

    Cut the key if needed

    If the key has a physical blade, we cut it on site to match your ignition and doors. When all keys are lost, the key can be cut by vehicle information rather than from an existing key, so you do not need a working original to get started.

  5. 5

    Program the transponder to the immobilizer

    We connect diagnostic equipment to the vehicle and register the new chip so the car accepts it. Where the process allows, we can add more than one key during the same visit, which is often the most economical way to get a spare.

  6. 6

    Test everything before we leave

    We start the engine, test the door locks, and check any remote functions together with you. You leave knowing the key works, not hoping it does.

What affects the price

  • Make, model, and year of the vehicle, since some immobilizer systems are simpler to work with than others
  • Key type: a basic chip key, a laser-cut key, a remote head key, and a smart or proximity key all involve different parts and effort
  • Whether you have a working key to copy from, or all keys are lost and the key must be originated from scratch
  • How many keys you want programmed in one visit, because additional keys are often easier to add while we are already connected to the car
  • Time of day and location, since we are available 24/7 and travel to you
  • Whether an old or failed key needs to be removed from the vehicle's memory for security reasons

Why West Hills chooses us

  • Fully mobile: we work at your car in West Hills, so there is no tow to a dealership and no storefront trip
  • Available 24/7, which matters when a key goes missing late at night or before an early shift
  • In business since 1987, with owner and lead tech David Shar overseeing the work
  • We explain whether your situation is a simple added key or an all-keys-lost job before work begins, so there are no surprises
  • Ownership verification on every job, because a programmed key is a security matter
  • We test the key, the doors, and any remote functions before we call the job finished

Transponder Key Programming across West Hills

West Hills stretches from the tract-home streets near Shadow Ranch Park to the hillside homes along the Valley Circle foothills at the Bell Canyon edge, and cars here tend to live in driveways, garages, and gated communities rather than in dense street parking. When a key stops working in the 91307 area, we can meet you at home. Whether you are in a 1970s tract house near Shadow Ranch or in a newer gated development off Valley Circle Blvd, we bring the programming equipment to the vehicle itself.

We also work in the Platt Village and Platt Ave corridor, where errands and school runs mean keys get dropped, bent, or left behind. Drivers in 91304 and 91308 call us from shopping lots along Roscoe Blvd, Victory Blvd, and Fallbrook Ave, and from work and visits at West Hills Hospital & Medical Center, where a long shift can end with a missing key. If you were hiking near Upper Las Virgenes Canyon or visiting Orcutt Ranch Horticultural Center and lost a key along the way, we can come to your parked car.

Households around Chaminade College Preparatory often have more than one driver and more than one key, and a spare programmed in advance is far easier than an emergency all-keys-lost call. If you are in West Hills and your car will not recognize its key, call (323) 997-8867 any hour.

Transponder Key Programming in West Hills — FAQs

What is a transponder key?
It is a key with a small chip inside the head that sends a coded signal to your car's immobilizer. If the code is not recognized, the engine will not start even if the blade turns the ignition.
Can you program a key if I lost all my keys in West Hills?
In many cases, yes. We can cut a key by vehicle information and program it to the car at your location. Call (323) 997-8867 with your vehicle details and we will tell you what to expect.
Do I have to tow my car to a dealership?
Usually not. We are fully mobile and bring the equipment to your vehicle, so the work is done in your driveway, a parking lot, or wherever the car is parked.
Will you need proof the car is mine?
Yes. We ask for registration and matching photo ID before programming a key. It is a security step that protects you and your vehicle.
Is a hardware store copy good enough?
A copy that only duplicates the metal will often turn the lock but will not start a chip-equipped car. The transponder must be programmed to the immobilizer for the engine to run.
Can you program more than one key at a time?
Often, yes. Adding a spare during the same visit is usually more practical than a second call later. Ask when you call (323) 997-8867.
How is the price determined?
It depends on the vehicle, the key type, whether you have a working key, how many keys you need, and the time and location. We explain the factors when you call rather than guess.
Do you work at night and on weekends?
Yes. We are available 24/7 and serve West Hills and the surrounding area, including 91307, 91304, and 91308.
