A transponder key looks like an ordinary key, but inside the plastic head is a small chip that talks to your car. When you turn the key or press the start button, the immobilizer checks for the right coded signal. If the signal is missing or wrong, the engine may crank but never start, or it will not crank at all. That is why a copy cut at a hardware counter often opens the door yet will not start the car. The chip has to be programmed to your specific vehicle.

In Ladera Heights, most of us park in our own driveways or garages rather than a crowded lot, which makes this a very workable job to do at home. Crenshaw Lock Company is fully mobile, so there is no shop to tow your car to. We bring the equipment to you, whether you are at a ranch-style home in Upper Ladera Heights, on a quiet street in Lower Ladera Heights, or in a parking spot by Ladera Center. We have been serving Greater Los Angeles and Ventura County since 1987, and David Shar leads the work.

People usually call us for one of a few reasons: they have lost their only key, they have one working key and want a spare before it is too late, a key has stopped starting the car, or they bought a used vehicle with a single key. Each situation is a little different, and we will tell you plainly what your car needs before we start. We are available around the clock, day or night.

How it works in Ladera Heights

  1. 1

    You call and describe the situation

    Call (323) 997-8867 and tell us the make, model, and year of the vehicle, and whether you have a working key. Tell us where the car is parked in Ladera Heights. We will explain what the job involves and what affects the cost, so there are no surprises.

  2. 2

    We come to your vehicle

    We are mobile only, so we drive to your driveway, street, or parking spot. Nothing needs to be towed. Be ready to show that you own the car, such as registration and your ID, because we confirm ownership before making keys.

  3. 3

    We identify the system and the key type

    We check the vehicle's immobilizer system and determine which kind of key it takes: a basic chip key, a flip key, a remote head key, or a push-button smart key. This decides what blank is needed and how it gets programmed.

  4. 4

    We cut the key if needed

    If your key has a physical blade, we cut it to match your vehicle's lock using the car's key code or by working from the lock itself. We test that the blade turns smoothly in the door and ignition before any programming starts.

  5. 5

    We program the chip to your immobilizer

    Using professional diagnostic and programming equipment, we pair the new key with the car's computer. If you have lost every key, the process can take longer than adding a spare to a car with a working key, but it can usually be done on site.

  6. 6

    We test everything before we leave

    We start the engine several times, test the locks and any remote buttons, and make sure each key works. We encourage you to keep the spare somewhere safe and separate from the main key.

What affects the price

  • Make, model, and year of the vehicle, since some manufacturers use more complex immobilizer systems than others.
  • Type of key needed: a basic chip key, a remote head key, a flip key, and a push-button smart key all involve different parts and different programming steps.
  • Whether you have a working key to copy or have lost all of your keys, which affects how much work the programming takes.
  • Whether the key blade also needs to be cut, or whether the job is programming only.
  • Time of day and urgency, since an after-hours or emergency call is different from a scheduled appointment.
  • Where the vehicle is located and how easily we can reach it for the work.

Why Ladera Heights chooses us

  • Fully mobile service. We come to your driveway or parking spot in Ladera Heights, so you never need to tow a car to a shop.
  • In business since 1987 across Greater Los Angeles and Ventura County, with owner and lead technician David Shar guiding the work.
  • 24/7 availability, because a car that will not start rarely picks a convenient hour.
  • We verify ownership before cutting or programming a key, which protects you and your vehicle.
  • We explain the job and the cost factors up front, and we will tell you if a dealer visit makes more sense for a particular vehicle.
  • One company for both car and home, so if you also need a rekey or a deadbolt upgrade at your house, we can handle that too.

Transponder Key Programming across Ladera Heights

Ladera Heights sits on a hill above the busy corridors of La Tijera Boulevard, La Cienega Boulevard, Slauson Avenue, Centinela Avenue, and La Brea Avenue, and most households here have more than one car. Many homes in Upper Ladera Heights and Lower Ladera Heights are mid-century and ranch-style houses on larger lots, with driveways and garages where a vehicle can be worked on comfortably. That suits mobile key programming well. We park, set up our equipment, and do the work at your home without moving the car.

We serve the 90056 and 90045 ZIP codes and the surrounding area. A call might come from a resident in a hillside home near Kenneth Hahn State Recreation Area who has misplaced a key fob, from a driver in the Ladera Center lot at La Tijera and Centinela whose car will not recognize its key, or from a student or staff member near West Los Angeles College on the Culver City side. We can also meet you near Holy Cross Cemetery if your car trouble starts away from home.

If you are already working with us on the house, such as rekeying a ranch home after a sale or upgrading to high-security deadbolts or a smart lock, it is easy to add a spare car key to the same visit. Call (323) 997-8867 any time, day or night.

Transponder Key Programming in Ladera Heights — FAQs

What is a transponder key?
It is a car key with a small chip inside the head. The chip sends a coded signal to your vehicle's immobilizer, and the engine will only start if the code matches. A key that is only cut, without programming, usually will not start the car.
Can you program a key at my home in Ladera Heights?
Yes. We are fully mobile and come to your driveway, garage, or street parking. There is no need to tow your car anywhere. Call (323) 997-8867 and tell us where the car is.
I lost all my keys. Can you still make a new one?
In most cases, yes. Having no working key makes the job more involved than copying from an existing key, but we can generally cut and program a new key on site. Call (323) 997-8867 and tell us the make, model, and year.
Is it cheaper to get a spare before I lose my only key?
Adding a key to a car that still has a working key is usually simpler than starting from nothing, so it often involves less work. Exact cost depends on your vehicle and key type, and we will walk you through the factors when you call.
Will you need proof that I own the car?
Yes. We ask for ID and proof of ownership, such as registration, before making a key. This protects you and keeps keys from being made for vehicles that are not yours.
Do you work on push-button start and smart keys?
We work on many vehicles with chip keys, remote head keys, flip keys, and smart keys, though coverage varies by make and model. Call (323) 997-8867 with your vehicle details and we will tell you honestly whether we can handle it.
Are you available at night or on weekends?
Yes. Crenshaw Lock Company is available 24/7. Because we are mobile, we come to wherever your vehicle is in Ladera Heights, at any hour.
Do I need to go to the dealer instead?
Often not. A mobile locksmith can usually program keys at your location without a tow or a dealership visit. For a few vehicles, the dealer may be the better route, and we will say so if that applies to yours.
