A transponder key looks like an ordinary key, but its plastic head holds a small chip that talks to your car's immobilizer. If the chip's code does not match what the car expects, the engine will not start, even when the blade turns the ignition. That is why a hardware-store copy often fails: it opens the door and then does nothing at the ignition. Programming is the step that teaches the car to accept a new key.

In Canoga Park, this usually comes up in a few familiar ways. Someone loses the only key at Westfield Topanga or Lanark Park. A spare is needed before the last working key disappears. Or a used car arrives with a single worn key and the owner wants a backup. Our work is fully mobile, so there is no shop to tow your car to. We come to the driveway, the apartment carport, or the parking lot where the car is.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, led by owner and lead technician David Shar. We are available around the clock, and we will tell you plainly what your vehicle needs before any work begins. Some cars are straightforward, while others need extra steps, and we explain which applies to yours.

How it works in Canoga Park

  1. 1

    Call and describe the situation

    Call (323) 997-8867 and tell us the make, model, and year, and whether you have a working key or have lost all of them. We ask where the car is parked so we can plan the visit to your location.

  2. 2

    Confirm ownership

    Before we cut or program any key, we ask for proof that the vehicle is yours, typically ID along with registration or title. It protects you and keeps keys from reaching the wrong hands.

  3. 3

    Identify the right key and system

    We check what type of chip and immobilizer your vehicle uses, then match the key blank and transponder to it. Some vehicles use a standard chip key, while others use a laser-cut blade or a remote head key.

  4. 4

    Cut the key if needed

    If the blade needs cutting, we do it on site. When all keys are lost, we can generate a cut from the lock or vehicle information rather than from an existing key.

  5. 5

    Program to the immobilizer

    We connect programming equipment to the vehicle and register the new key with the car's computer. Depending on the vehicle, existing keys may be kept or re-registered during this step.

  6. 6

    Test everything before we leave

    We try the key in the door and the ignition, start the engine, and test any remote buttons. You see it all working before the job is finished.

  • How many keys you want programmed during the same visit.
  • Whether the blade needs cutting and how complex the cut is.

Transponder Key Programming across Canoga Park

Canoga Park is a car-dependent part of the West San Fernando Valley, and most of our transponder calls come from the places people park. That includes the carports of 1950s dingbat apartments off Sherman Way, the driveways of tract homes in the Owensmouth area, and the lots behind mid-century strip retail along Sherman Way. A lost key in a shared apartment lot is a different problem than a dead key at Lanark Recreation Center, and we plan the visit around where you actually are.

Getting around here means Sherman Way, Roscoe Boulevard, Vanowen Street, Saticoy Street, Victory Boulevard, Topanga Canyon Boulevard, and the US-101 for longer trips. We cover ZIP codes 91303, 91304, 91305, and 91309, including the Gault Street and Topanga area near Warner Center, where office and shopping parking brings its own lost-key emergencies.

We do not run a storefront, so there is nothing to visit. If you are near Canoga Park High School, the Madrid Theatre, or Westfield Topanga and cannot start your car, call (323) 997-8867 and we will come to you.

Transponder Key Programming in Canoga Park — FAQs

Can you program a transponder key if I lost all my keys?
In many cases, yes. We can cut a key and program it to your immobilizer on site even with no working key. Call (323) 997-8867 with your vehicle details and we will tell you what your car requires.
Do you come to me in Canoga Park?
Yes. We are fully mobile, so we come to your car at home, work, or wherever it is parked in 91303, 91304, 91305, or 91309. There is no shop to visit.
Why won't my copied key start the car?
A key that only has the right blade shape will turn the lock but not start the engine. The chip also has to be programmed to your car's immobilizer, which is what we do.
Is it cheaper to program a spare before losing my last key?
Usually it is simpler, because we can copy from a working key rather than starting from nothing. Cost depends on your vehicle and key type, so call (323) 997-8867 to discuss it.
Are you available at night or on weekends?
Yes. We are available 24/7 and mobile, so nights, weekends, and holidays are covered.
What do I need to show you?
We ask for proof of ownership, typically photo ID along with the registration or title. We do this on every job before programming.
Can you program remote buttons too?
For many vehicles we can program remote functions along with the transponder. It depends on the make and year, so tell us your vehicle when you call.
How do I get a quote?
Call (323) 997-8867 and give us the make, model, year, and how many keys you have. We will explain what affects the cost for your situation.
