A modern car key is more than a cut piece of metal. Inside the plastic head sits a small transponder chip that has to be recognized by the vehicle's immobilizer before the engine will run. If the chip is not programmed to the car, the key may turn in the ignition and still do nothing. That is why a hardware-store copy so often fails, and why a lost or broken key can leave a car stuck where it sits.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and we are fully mobile. There is no storefront to drive to. In Rolling Hills Estates, that matters. Many residents live in hillside and equestrian neighborhoods where a tow truck is a hassle, and many others park at the Promenade on the Peninsula or along Hawthorne Boulevard, where a dead key means a stranded car. We bring the programming equipment to wherever the vehicle is.

Owner and lead technician David Shar and our team handle transponder work for spare keys, replacement keys after a loss, and keys that have stopped communicating with the car. Because every make, model, and year behaves a little differently, we start by confirming what your vehicle needs rather than promising an outcome before we have seen it.

How it works in Rolling Hills Estates

  1. 1

    Call and describe the situation

    Call (323) 997-8867 any hour. Tell us the make, model, and year, whether you still have a working key, and where the car is parked. That tells us whether this is a simple added spare or a lost-all-keys situation.

  2. 2

    We come to the vehicle

    We are fully mobile, so we drive to your driveway, a parking space near Peninsula Center, or the side of a road. Nothing needs to be towed for us to begin.

  3. 3

    Verify ownership

    Before we create or program any key, we ask for reasonable proof that the vehicle is yours, such as registration and matching ID. It protects you and every other owner.

  4. 4

    Cut and prepare the key

    If the key needs a blade, we cut it to the vehicle's code or lock. We make sure the key or fob hardware is compatible with your car's immobilizer system before programming.

  5. 5

    Program to the immobilizer

    We connect our programming equipment and register the new transponder with the car's computer. Where the vehicle allows it, we also add or retain existing keys so all of them work together.

  6. 6

    Test everything

    We test the key in the door, the ignition or push-button start, and any remote functions. You see it start the car before we consider the job done.

What affects the price

  • Make, model, and year, since some immobilizer systems are far more involved to program than others.
  • Whether you have a working key already, or all keys are lost and a new one must be created from scratch.
  • Type of key: basic chip key, flip key, remote head key, or smart proximity fob all differ in hardware and effort.
  • Whether the key blade needs to be cut, and whether it is a standard or high-security laser-cut style.
  • Time of day and location, since we are available around the clock and travel to the vehicle.
  • Number of keys needed, such as adding a spare along with the replacement.

Why Rolling Hills Estates chooses us

  • Fully mobile service. We program keys at your car, so you avoid towing a vehicle off a hillside street or out of a shopping center lot.
  • In business since 1987, with David Shar as owner and lead technician rather than a faceless dispatch center.
  • Honest scoping. We tell you up front if a particular vehicle may need dealer-only steps, instead of overpromising.
  • 24/7 availability, so a dead key at night or on a weekend does not have to wait for dealership hours.
  • Ownership verification on every job, which keeps your vehicle from being keyed up for someone else.
  • We test before we leave, including remote and push-start functions, so you know the key works.

Transponder Key Programming across Rolling Hills Estates

Rolling Hills Estates sits on the Palos Verdes Peninsula, and vehicles here live a varied life. Residents in Dapplegray and Georgeff Canyon often park at horse-property homes with long driveways and trailer-friendly lots, where having a technician come to the car is far easier than arranging a tow. In Chandler Ranch and the newer gated-community streets, we work in driveways and guest parking where access is sometimes arranged ahead of time, so it helps to tell us about gate codes when you call.

Shoppers and workers around Peninsula Center and the Promenade on the Peninsula on Deep Valley Drive sometimes find a key has stopped starting the car, or has gone missing mid-errand. We can meet you in the lot, verify the vehicle, and program a replacement on site. The same goes for commuters along Hawthorne Boulevard, Silver Spur Road, Palos Verdes Drive North, and Crenshaw Boulevard, and for people visiting Ernie Howlett Park, the bridle trails, or the neighboring South Coast Botanic Garden.

We serve ZIP codes 90274 and 90275 and the surrounding area. If your car is in a condo or townhome garage near Silver Spur Road, or in a driveway at one of the 1960s and 70s ranch homes, call (323) 997-8867 and tell us where it is parked. We will come to you.

Transponder Key Programming in Rolling Hills Estates — FAQs

What is a transponder key?
It is a key with a small chip inside the head that communicates with your car's immobilizer. The engine will only start if the chip's code is recognized, which is why a plain cut key often will not work.
Can you program a key at my home in Rolling Hills Estates?
Yes. We are fully mobile, so we come to your driveway, garage, or wherever the car is parked. Call (323) 997-8867 to arrange it.
I lost all my keys. Can you still help?
In many cases, yes. A lost-all-keys job usually takes more work than adding a spare, and results depend on the vehicle. Call (323) 997-8867 with the make, model, and year and we will tell you what to expect.
Do I need to tow my car to you?
No. We have no storefront, and we bring the equipment to the vehicle. That is especially convenient on hillside streets or at a shopping center lot near Peninsula Center.
Why not just get a copy cut at a hardware store?
A cut copy opens the door but often lacks a programmed chip, so it will not start the car. A transponder key must be programmed to the immobilizer to work.
Will you need proof that the car is mine?
Yes. We ask for reasonable proof of ownership, such as registration and matching ID, before creating or programming a key. It is a standard safeguard.
Do you work nights and weekends?
Yes. We are available 24 hours a day, 7 days a week. Call (323) 997-8867 whenever you need us.
How is the price determined?
It depends on the vehicle, key type, whether you have a working key, whether the blade must be cut, how many keys you need, and when and where we are called out. We will go over those factors when you call.
