A transponder key looks like an ordinary key, but inside the plastic head is a small chip that talks to your car's immobilizer. If the chip's code isn't recognized, the engine may turn over briefly and then shut down, or it won't start at all. That is why a copy cut at a hardware counter often opens the door but never starts the car. The key has to be cut correctly and then programmed to the vehicle.

In Calabasas, this comes up in everyday ways. Someone loses their only key at The Commons at Calabasas, a household finds its last working key has died after years of use, or a family realizes they never had a spare for a newer SUV that spends its days on US-101 and Las Virgenes Road. Waiting until the last key is gone usually makes the job more involved, so a spare is worth arranging early.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and David Shar leads the work. We are fully mobile, so there is no shop to tow your car to and no storefront to visit. We bring the equipment to your driveway, your office lot, or wherever the vehicle is parked, and we are available around the clock.

How it works in Calabasas

  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 still have a working key. Whether you are adding a spare or replacing every key you had changes the approach, so we ask a few questions up front.

  2. 2

    We come to the vehicle

    Because we are fully mobile, we meet you where the car is, whether that is a home driveway in Calabasas Hills, a parking spot near Old Town Calabasas, or a lot off Parkway Calabasas. You do not need to move or tow the car.

  3. 3

    Verify ownership

    Before we create a key for any vehicle, we confirm that you are the owner or an authorized user. This protects you and is a normal part of responsible automotive locksmith work.

  4. 4

    Cut the key blank to match

    If the key needs cutting, we cut the blade to fit the ignition and door locks. Depending on the vehicle, that may be a traditional edge-cut key or a laser-cut key, and some systems use a push-button start fob instead of a blade key.

  5. 5

    Program the chip to the immobilizer

    We connect programming equipment to the vehicle and register the new transponder so the immobilizer accepts it. When appropriate, we can also remove a lost key from the system so it no longer starts the car.

  6. 6

    Test everything before we leave

    We confirm the key opens the doors, turns the ignition, and starts the engine, and that remote functions work where applicable. You see it working before the job is finished.

What affects the price

  • Vehicle make, model, and year, since some immobilizer systems are simpler to program than others
  • Whether you have a working key to copy or all keys are lost, which changes the programming procedure
  • Type of key: standard transponder blade, laser-cut key, or proximity fob for push-button start
  • How many keys you want programmed in the same visit

  • Time of day and location, since we are available 24/7 and travel to you

Transponder Key Programming across Calabasas

Calabasas has a mix of driving habits that make spare keys especially worthwhile. Residents in The Oaks, Calabasas Hills, and Mulwood commute along US-101, run errands on Calabasas Rd and Parkway Calabasas, and head out to Malibu Creek State Park or King Gillette Ranch on weekends. A key lost on a trail or at Calabasas Lake can leave a car stranded far from home, and having a programmed spare can prevent that.

Guard-gated communities add a small complication. If a vehicle is stuck inside a gated neighborhood, we coordinate with the gatehouse so we can reach you. For addresses in ZIP code 91302, just give us the street and any gate instructions when you call, and we will plan the visit around them.

Whether you are parked at The Commons at Calabasas, near Old Town Calabasas, or in a driveway off Las Virgenes Road or Old Topanga Canyon Rd, we come to you. Call (323) 997-8867 any hour.

Transponder Key Programming in Calabasas — FAQs

What is a transponder key?
It is a key with a small chip in the head that communicates with your car's immobilizer. The engine will only run if the car recognizes the chip's code, so the key must be programmed as well as cut.
Can you program a key if I lost all my keys?
In many cases, yes. All-keys-lost situations are more involved than copying a working key, but we can often handle them on site. Call (323) 997-8867 with your vehicle details and we will tell you what to expect.
Do I need to bring my car to you?
No. We are fully mobile and there is no storefront. We come to your car anywhere in Calabasas, including driveways, parking lots, and gated communities.
Can you work inside a gated community like The Oaks?
Yes. We coordinate with the gatehouse so we can reach your vehicle. Let us know the address and any access instructions when you call.
Why won't a key from a hardware store start my car?
A basic copy only cuts the blade. Without a chip programmed to your immobilizer, the car will not start, even if the key turns in the ignition.
Can you erase a lost key from the car's memory?
Often we can, depending on the vehicle. Removing a lost key means it can no longer start the car, which is a good step if the key may have been stolen.
Do you offer this service at night or on weekends?
Yes. We are available 24/7. Call (323) 997-8867 any time and we will get you scheduled.
How do you decide on the price?
The price depends on the vehicle, the key type, how many keys you need, and whether you have a working key. We explain what applies to your situation when you call.
