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 vehicle's immobilizer checks for the chip's coded signal. If the code does not match, the engine will not run, even if the metal blade turns the ignition. That is why a copy cut at a hardware counter often opens the door but will not start the car. The chip has to be programmed to the vehicle.

In a city built around the automobile, this comes up constantly. Lakewood grew up in the early 1950s as a commuter suburb, and its residents still depend on cars to get to jobs along the I-605 and SR-91 corridors, to shop at Lakewood Center, and to run errands along Lakewood Blvd and Del Amo Blvd. Losing the only working key, or having a key stop starting the car, can disrupt a whole week.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, led by owner and lead technician David Shar. We are fully mobile. There is no shop to drive to and no tow to arrange. We meet you where the car is parked, whether that is a driveway in Lakewood Village, a lot near The Centre at Sycamore Plaza, or the side of the road, and we handle the programming on site.

How it works in Lakewood

  1. 1

    Call and describe the situation

    Phone (323) 997-8867 any hour. Tell us the vehicle's make, model, and year, where it is parked, and whether you have one working key, a key that is not starting the car, or no key at all. That tells us what we need to bring and what the job will involve.

  2. 2

    Confirm ownership

    Before we cut or program anything, we ask you to show that the vehicle is yours, typically with a photo ID and registration or similar documentation. This protects you and keeps the work responsible, and it is a normal part of any legitimate automotive locksmith job.

  3. 3

    Identify the key and immobilizer type

    Vehicles use different chip types and security systems. We check the vehicle details, determine what key blank and transponder it needs, and confirm the right programming method for that system.

  4. 4

    Cut and prepare the key

    If the key needs a physical blade, we cut it to match your vehicle's lock. For vehicles that use a push-button start, the key may be a fob instead, and we prepare it for the vehicle accordingly.

  5. 5

    Program the chip to the vehicle

    We connect our programming equipment to the vehicle and register the new key to its immobilizer. Depending on the vehicle, this may also involve working with the car's computer in an all-keys-lost situation.

  6. 6

    Test everything before we leave

    We confirm that the key starts the engine, that the door and remote functions work where applicable, and that any existing keys still operate. You should walk away knowing the key works, with no guesswork.

What affects the price

  • Vehicle make, model, and year, since some immobilizer systems are more involved to program than others
  • Whether you still have a working key to copy or all keys are lost, which changes the programming method
  • The type of key needed, such as a basic transponder key, a flip key, or a smart key or push-button fob
  • How many keys need to be programmed in a single visit
  • Where and when the vehicle is located, including after-hours or hard-to-reach locations
  • Whether the key blade must be cut or the lock itself has issues that need attention

  • In business since 1987, with owner David Shar leading the work
  • We verify ownership before programming, which protects you and your vehicle
  • We test the key fully before leaving, including starting the engine
  • We explain the options plainly, so you can choose between a basic transponder key and other key types knowing what each involves

Transponder Key Programming across Lakewood

Lakewood is a flat, grid-like suburb, and most of our calls here involve cars parked on residential streets or in driveways in neighborhoods like Lakewood Village, Lakewood Park, and Carson Park. The single-story ranch homes built in the early 1950s were designed around the garage and driveway, and many households today have two or three vehicles with a mix of older and newer key technology. That makes transponder programming a regular need, whether it is a spare key for a teenager's first car or a replacement after the only key went missing.

We also see calls tied to the city's retail and commuter activity. Cars parked around Lakewood Center, The Centre at Sycamore Plaza, Rynerson Park, or Mayfair Park can end up with a lost key after a long day, and drivers who commute on the I-605, SR-91, Del Amo Blvd, or Carson St sometimes discover a key problem only when they are ready to head home. Because we are mobile, we can meet you at the parking lot or curb instead of requiring a tow.

We serve all of Lakewood, including ZIP codes 90711, 90712, 90713, 90714, and 90715. If you are in 90712 near Lakewood Blvd or anywhere else in the city, call (323) 997-8867 and we will talk through your vehicle and where you are.

Transponder Key Programming in Lakewood — 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 run if the code matches. That is why a plain metal copy usually will not start a modern car.
Can you program a transponder key if I lost all my keys?
In many cases, yes. All-keys-lost situations take more work than copying from an existing key, but we can often cut and program a new one on site. Call (323) 997-8867 with your vehicle details and we will tell you what to expect.
Do I need to tow my car to you?
No. We are fully mobile and come to your vehicle in Lakewood, whether it is at home, at work, or in a parking lot. We do not operate a storefront, so there is nothing to tow to.
Will you need proof that the car is mine?
Yes. We ask for identification and documentation showing ownership, such as registration, before programming a key. It is a standard safeguard that protects you.
Is a locksmith copy cheaper than going through a dealer?
We will not quote a figure here, since cost depends on your vehicle and key type. A mobile locksmith can often save you the tow and the trip, but the best way to compare is to call (323) 997-8867 and describe your situation.
Can you program a spare key even though my current key works?
Yes, and it is often the easiest time to do it. Having a working key to start from usually makes the job simpler than waiting until all keys are lost, and a spare can save you trouble later.
Do you handle push-button start and smart keys?
Many vehicles with push-button start use a smart key or fob that must be registered to the car. Whether we can do your vehicle depends on its make, model, and year, so please call us with those details.
Are you available at night or on weekends in Lakewood?
Yes. We are available 24 hours a day, 7 days a week. If you are stuck with a car that will not start because of a key problem, you can reach us at (323) 997-8867 at any hour.
