A modern car key is more than a cut piece of metal. Inside the plastic head is a small transponder chip that talks to your vehicle's immobilizer. If the car does not recognize the chip, the engine will not start, even when the key turns in the ignition. That is why a lost key, a single worn-out spare, or a hardware-store copy that turns but will not start can leave you stuck. Crenshaw Lock Company programs these keys on site, so the vehicle never has to be towed anywhere.

We are a fully mobile locksmith. There is no storefront to visit; the work happens wherever your car is parked. In a small, tightly built city like Lomita, that might be a driveway in Harbor Hills, a curb along Lomita Boulevard near City Center, a carport behind an apartment building, or a lot along the Narbonne Avenue corridor. Our crew has served Greater Los Angeles and Ventura County since 1987, and owner and lead tech David Shar has spent decades around vehicle locks and keys.

People usually call us in a few situations: they have lost their only key, they want a spare before that happens, a key stopped communicating with the car, or they bought a used vehicle with just one key. Each case is a bit different, and we explain what your particular vehicle needs before any work begins. We are available around the clock, including nights, weekends, and holidays.

How it works in Lomita

  1. 1

    Call and describe the situation

    Call (323) 997-8867 and tell us the year, make, and model, where the car is parked, and whether you have any working key. Whether it is a spare, an all-keys-lost situation, or a key that stopped starting the car changes the approach, so these details help us prepare.

  2. 2

    We drive to your vehicle

    Because we are fully mobile, we travel to you, whether that is a Harbor Hills street, a Lomita Boulevard apartment lot, or a spot near Pacific Coast Hwy. We make no timing promises over the phone, but we are staffed 24/7 and treat a stranded driver as a priority.

  3. 3

    Verify ownership

    Before we create or program a key, we ask for proof that the vehicle is yours, typically a photo ID and registration or title. It protects you and keeps keys from reaching the wrong hands.

  4. 4

    Identify the key and immobilizer system

    We confirm the correct blank, chip type, and programming method for your vehicle. Some cars accept a new key through an onboard procedure; others require diagnostic equipment connected to the vehicle's data port.

  5. 5

    Cut and program the key

    We cut the blade if the key has one, then program the transponder so the immobilizer accepts it. If the key also has remote buttons, we can often program those in the same visit, depending on the vehicle.

  6. 6

    Test everything before we leave

    We start the engine, test the door locks, check the remote functions, and confirm that every key you have works. We recommend programming a spare at the same time so you are not in this spot again.

What affects the price

  • Vehicle make, model, and year, since some immobilizer systems are far more involved than others
  • Whether you have a working key to copy or all keys are lost, which changes the programming procedure
  • The type of key: basic chip key, flip key, or smart proximity key
  • Whether remote buttons or a keyless entry fob also need programming
  • How many keys you need programmed in a single visit
  • Time of day and your location, since late-night and after-hours calls can affect the job

Transponder Key Programming across Lomita

Lomita covers only about 1.9 square miles, but its streets get plenty of vehicle traffic. Residents in Harbor Hills park in driveways and on the street, while people along Lomita Boulevard and the City Center area often rely on lots shared with apartment buildings. Along the Narbonne Avenue commercial corridor, we help drivers who lose a key during errands or work. In ZIP code 90717, we go wherever the vehicle is parked, from a quiet residential block to a spot near Lomita Park or the Lomita Railroad Museum.

Many homes here date from the 1940s through the 1960s, and many households have several drivers sharing a driveway or carport. That makes a spare key especially useful. A single lost key on a family car can be solved quickly with a programmed duplicate, ideally made before the original goes missing. Apartment residents on Lomita Boulevard often have assigned parking, so we can meet you right at your space.

Lomita is also a gateway to the Palos Verdes Peninsula, and plenty of drivers travel Pacific Coast Hwy, Western Ave, and Narbonne Ave daily. If your key fails on the way home or before your commute, call (323) 997-8867 and we will come to you.

Transponder Key Programming in Lomita — FAQs

What is a transponder key?
It is a key with a small chip inside that sends a coded signal to your vehicle's immobilizer. The engine will only start if the car recognizes the code, which is why a plain cut key often will not work.
Can you program a key at my home in Lomita?
Yes. We are fully mobile and come to your driveway, street, or apartment parking space anywhere in Lomita, including Harbor Hills and the Lomita Boulevard area. Call (323) 997-8867 to get started.
I lost all my keys. Can you still help?
In most cases, yes. An all-keys-lost situation usually takes more equipment than adding a spare, but we can typically create and program a new key at the vehicle. We will confirm what your car requires when you call.
Do I need to prove I own the car?
Yes. We ask for identification and proof of ownership, such as registration or title, before making or programming a key. This protects owners from unauthorized key requests.
Can you program the remote buttons too?
Often we can, depending on the vehicle and the type of remote. Let us know when you call whether you need just the starting function or the lock and unlock buttons as well.
How much does transponder key programming cost?
It depends on your vehicle, the type of key, whether you have a working key, and how many keys you need. We explain the factors and the total before we begin. You can ask for details at (323) 997-8867.
Are you available at night or on weekends?
Yes. We are available 24/7, including nights, weekends, and holidays. We do not give arrival-time promises, but our service is built around coming to you.
Should I get a spare key before I lose mine?
Yes, it is generally easier and often less involved to duplicate a key while you still have a working one. If you are in Lomita and want a spare programmed, call (323) 997-8867 to schedule a visit.
