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 ignition or press start, the immobilizer checks for the right coded signal. If the chip is missing, unregistered or damaged, the engine may crank without starting, or not crank at all. That is why a hardware-store copy that only matches the metal blade will open the door but never run the car.

In Artesia, this comes up in everyday ways: a spare that was never made for a family car parked in a compact driveway off South Street, a key that went missing after a long dinner on Pioneer Boulevard, or a fob that quit working halfway through a commute on the SR-91. Dealerships often mean towing the car and waiting on their schedule. We are fully mobile, so the work happens where the car is sitting.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, under owner and lead technician David Shar. We have no storefront; everything is done at your location. This page explains how programming works, what affects the cost, and what to expect when you call.

How it works in Artesia

  1. 1

    You call and describe the vehicle

    Call (323) 997-8867 and tell us the make, model, year and where the car is parked. We will ask whether you have any working key, because that changes the approach. Having a working key is usually simpler than starting from nothing, but neither situation is unusual.

  2. 2

    We come to your car

    Our technician drives to you with cutting and programming equipment. Whether you are in a driveway near Artesia Park, a lot along Pioneer Blvd, or a street in Downtown Artesia, the work is done on site. There is no tow needed and no trip to a shop.

  3. 3

    Verify ownership

    Before creating a key for any vehicle, we ask for proof that it is yours, such as ID and registration or title. This protects you and keeps vehicle theft from being made easier. It is a standard part of responsible automotive locksmith work.

  4. 4

    Cut the key blade

    If the key needs a physical cut, we cut the blade to your door and ignition. For many vehicles this can be done from the lock code or by decoding the lock itself, which matters when all keys are lost.

  5. 5

    Program the transponder to the immobilizer

    We connect diagnostic equipment to the vehicle and register the new chip so the immobilizer accepts it. Depending on the vehicle, this may also involve erasing lost keys from the car's memory so a missing key can no longer start it.

  6. 6

    Test everything before we leave

    We test the door lock, ignition, and any remote buttons, and start the engine with the new key several times. You should leave with keys that work and a clear idea of whether a spare is worth making.

What affects the price

  • Make, model and year of the vehicle, since immobilizer systems differ widely between manufacturers and even between model years.
  • Whether you have a working key to copy or all keys are lost, which changes the amount of work involved.
  • The type of key: a basic chip key, a laser-cut key, a switchblade key or a push-button start smart key each need different parts and procedures.
  • How many keys you need programmed in one visit, since adding a spare during the same trip is often more efficient than coming back later.
  • Whether remote lock and unlock buttons need programming along with the transponder chip.
  • Time of day and location, since we operate around the clock and travel to you across the area.

Why Artesia chooses us

  • Fully mobile service: the programming equipment comes to your vehicle, so you avoid towing a car that otherwise runs fine.
  • In business since 1987, so our technicians have worked on a long span of vehicle generations, from early chip keys to current smart keys.
  • Owner involvement: David Shar leads the work, and you speak with a locksmith who knows the trade, not a call center.
  • Ownership verification on every job, which keeps the process legitimate and protects your vehicle.
  • Straightforward explanations of what is needed. We tell you if a cheaper option, like cloning a working key, makes sense for your car.
  • Available 24/7, which matters when a lost key strands you late at night or early before work.

Transponder Key Programming across Artesia

Artesia is a small city with a big presence in southeast Los Angeles County. It began as dairy country, settled by Dutch and Portuguese dairymen, and the DES Portuguese Hall and Artesia Historical Museum still recall that history. Today the residential core has modest post-war single-family homes on compact lots, where driveway parking is tight and a lost car key can leave a household with one vehicle short for the day. We serve addresses throughout ZIP codes 90701 and 90702.

The busiest part of town for cars is the Little India district along Pioneer Boulevard. Shoppers, restaurant guests and workers fill the street and the lots behind it, and keys do get dropped, left in jackets, or locked inside. Business owners and employees who drive to Pioneer Blvd every day also need dependable spares. Because we are mobile, we can meet you in a lot in Little India or in Downtown Artesia, and program the key without moving the vehicle.

Many Artesia drivers rely on SR-91, South Street and Gridley Road for commuting. A key that stops starting the car on a workday is more than an inconvenience. If it happens to you, call (323) 997-8867, tell us where you are parked, and we will take it from there. We do not have a shop to visit; the service comes to you.

Transponder Key Programming in Artesia — FAQs

What is a transponder key?
It is a key with a small chip in the head that sends a coded signal to your car's immobilizer. The engine will only run if the car recognizes that code. Programming registers a new chip so the car accepts it.
Can you program a key in Artesia if I lost all my keys?
Yes. All-keys-lost situations are common. We verify ownership, cut a key to your vehicle, and program it to the immobilizer on site. Call (323) 997-8867 with your vehicle details to start.
Do I need to tow my car?
Generally no. We are fully mobile and bring the equipment to wherever the car is parked, whether that is a driveway in the residential core or a lot near Pioneer Blvd.
Is a hardware-store copy good enough?
A copy that only duplicates the metal cut may open the door and even turn the ignition, but the engine will not run without a properly programmed chip. Programming is the step that makes the key actually work.
What do you need from me to make a key?
We ask for proof of ownership, such as photo ID along with registration or title. This protects you and is a standard part of legitimate automotive locksmith work.
Can you also program the remote buttons?
For many vehicles, yes. Tell us when you call whether you need the remote lock and unlock functions as well, and we will confirm what is possible for your make and model. You can reach us at (323) 997-8867.
Will the old lost key still start my car?
On many vehicles we can remove lost keys from the immobilizer's memory during programming, so a missing key can no longer start the car. Ask us about this for your specific vehicle.
How is the price determined?
It depends on the vehicle, key type, whether you have a working key, how many keys you need and the remote functions required. We do not quote numbers on a web page; call (323) 997-8867 and describe the situation so we can explain your options.
