Most cars built since the late 1990s will not start with a plain metal key. Inside the plastic head of the key is a small transponder chip, and the car's immobilizer must recognize that chip before it lets the engine run. If you have lost your only key, snapped one, or bought a blank online that will not start the car, the key has to be cut and programmed to your specific vehicle.

Crenshaw Lock Company is fully mobile, so there is no shop to tow your car to. In Willowbrook we work where you are parked: in a driveway on a quiet street of 1950s homes, in a lot near the Willowbrook/Rosa Parks station, or at the curb outside a medical office. We have served Greater Los Angeles and Ventura County since 1987, and owner David Shar leads the work.

Programming differs a great deal between makes, models and years. Some vehicles accept a new key quickly when a working key is present. Others require specialized equipment to communicate with the car's computer, especially when all keys are lost. We will tell you what your vehicle needs before work begins, and we are available around the clock.

How it works in Willowbrook

  1. 1

    Call and describe the situation

    Call (323) 997-8867 and tell us the make, model and year, and whether you have a working key or have lost them all. That determines the approach and the equipment we bring.

  2. 2

    We travel to your vehicle

    Because we are mobile and available 24/7, we come to you in Willowbrook, whether you are at home, at work, or stranded along a road like Imperial Highway or Alondra Boulevard.

  3. 3

    Verify ownership

    Before creating a key for any vehicle, we ask for identification and proof of ownership, such as registration or title. This protects you and keeps keys out of the wrong hands.

  4. 4

    Cut the key or blank

    If the key needs a physical cut, we cut it to fit your locks. Many modern keys also use a laser-cut or proximity design, which we handle with the correct blank.

  5. 5

    Program the transponder

    We connect programming equipment to the vehicle and register the new chip with the immobilizer. Depending on the car, this may also involve erasing a lost key so it no longer starts the vehicle.

  6. 6

    Test everything

    We test the key in the door, trunk if applicable, and ignition, and start the engine several times. You do not pay for a key you have not seen work.

Transponder Key Programming across Willowbrook

Willowbrook is a working-class community where many people depend on their cars to get to jobs, school and medical appointments. Losing the only key can disrupt an entire week. We serve drivers in 90059, 90061 and 90222, including those near the Willowbrook/Rosa Parks transit district, the MLK Jr. Medical Campus area, and neighboring Watts and Compton.

We often see situations tied to how people live here. A resident parks on the street in front of a 1950s stucco house with no driveway space and loses a key. A hospital or university employee near MLK Jr. Community Hospital or Charles R. Drew University leaves a shift and cannot find a key in the parking area. A commuter who rides the A or C Line from Imperial Highway and Wilmington Avenue returns to a parked car with a broken key. We come to each of them.

With I-105 and I-110 close by, plus Wilmington Avenue and Central Avenue as main corridors, a breakdown or lost key can happen on a busy route. Call (323) 997-8867 and we will find the best way to reach you. If you also need a rekey after a break-in or work on a security door, we can handle that too.

Transponder Key Programming in Willowbrook — FAQs

Do you come to me in Willowbrook for transponder key programming?
Yes. We are fully mobile and available 24/7, so we program keys at your car in Willowbrook. Call (323) 997-8867 to get started.
Can you program a key if I lost all of my keys?
In many cases yes. All-keys-lost situations are more involved than copying from a working key, and the answer depends on the vehicle. Call (323) 997-8867 with your make, model and year.
Is a locksmith key cheaper than going to a dealer?
Often a mobile locksmith is more convenient because there is no towing to a dealership. Cost depends on the vehicle and key type, so we discuss it with you before work starts.
Can you program a key I bought online?
Sometimes. Compatibility depends on the key type and vehicle. Some online keys are locked or the wrong chip type, so we check before we try. Call (323) 997-8867 to ask.
What proof of ownership do I need?
We ask for identification and something showing you own the vehicle, like a registration or title. This is standard for responsible key making.
Will my old lost key still start the car?
On many vehicles we can remove lost keys from the immobilizer's memory so they no longer work. We can discuss whether this is possible for your car.
Do I need a spare key too?
A spare is strongly worth considering. Making one while you still have a working key is generally simpler than handling an all-keys-lost situation later.
Can I visit your shop in Willowbrook?
We are mobile only and do not have a storefront. We come to you, any hour of the day or night. Call (323) 997-8867 to arrange service.
