If your car has a chip in the key head, the engine will not stay running unless the car's immobilizer recognizes that chip. A cut blade alone is not enough. That is why a spare from a hardware kiosk sometimes turns the ignition but never starts the engine. Programming is the step that teaches the car to accept a new key.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and owner and lead tech David Shar has seen how much this work has changed. We are fully mobile. There is no shop to tow your car to, because we bring the equipment to wherever the car is parked, whether that is a driveway in Toluca Woods or a curb near the Metro station.

People in North Hollywood usually call us in a few situations: they lost the only key, they want a spare before that happens, a key stopped being recognized, or a used car came with one key and no backup. Each case is a little different, and we will tell you plainly what your vehicle needs before any work begins.

How it works in North Hollywood

  1. 1

    Call and describe the vehicle

    Phone us at (323) 997-8867 any hour. Tell us the make, model, and year, where the car is, and whether you still have a working key. Those details shape what we bring and what to expect.

  2. 2

    We come to the car

    Because we are fully mobile, we drive to you, whether the car is at home, at work, or in a parking structure. Nothing needs to be towed for most key situations.

  3. 3

    Verify ownership

    Before cutting or programming anything, we ask for proof that the vehicle is yours, such as registration and matching photo ID. This protects you and is standard responsible practice.

  4. 4

    Cut and prepare the key

    If the key needs a blade, we cut it to the vehicle's lock. We then confirm the transponder chip or smart key hardware is compatible with your car.

  5. 5

    Program to the immobilizer

    We connect programming equipment to the vehicle and register the new key so the immobilizer accepts it. Depending on the car, existing keys may also be re-registered.

  6. 6

    Test everything

    We test the door, ignition, and start function with each key before we finish. You leave knowing every key works.

Transponder Key Programming across North Hollywood

North Hollywood is a car-and-transit neighborhood. Many residents commute by the B Line from the North Hollywood Metro Station, while others rely on the US-101 and SR-170 freeways. That mix means cars often sit parked for long stretches, and a lost or failing key can leave you stuck. We serve the NoHo Arts District, North Hollywood West, and Toluca Woods, and we cover ZIP codes 91601, 91602, 91605, 91606, and 91607.

Parking varies a lot here. Apartment dwellers near Lankershim Boulevard and Magnolia Boulevard often park in tight lots or on the street, and newer mid-rises near the station have garages. Older bungalow streets have driveways. We work in all of these settings and bring programming equipment to wherever your car is.

If you are near the El Portal Theatre, the Television Academy, or along Vineland Avenue or Victory Boulevard and your key has failed, call (323) 997-8867. We are mobile only, so there is no storefront to visit. We come to you.

Transponder Key Programming in North Hollywood — FAQs

What is transponder key programming?
It is the process of registering a chip key with your vehicle's immobilizer so the engine will start. Without it, even a perfectly cut key will not run the car.
Can you program a key if I lost all my keys in North Hollywood?
In many cases yes. All-keys-lost situations take a different procedure than adding a spare, but we handle them at your vehicle. Call (323) 997-8867 and tell us the make, model, and year.
Do I need to tow my car to you?
Usually not. We are fully mobile and bring the equipment to your car, whether you are in the NoHo Arts District or parked near the Metro station.
Are you available at night or on weekends?
Yes. We operate 24/7. Call (323) 997-8867 whenever you need help.
What proof of ownership do I need?
We ask for matching photo ID and vehicle registration or similar documentation. We verify ownership before creating or programming a key.
Is a dealership key cheaper than a locksmith key?
It depends on the vehicle. Dealers often require towing and an appointment, while we come to you. Price depends on factors like the key type and your car's system, which we explain before starting.
Can you program smart keys and push-button fobs?
Many vehicles are supported, though it depends on the make and model. Tell us your vehicle when you call so we can confirm what is possible.
Should I get a spare key before I lose the only one?
Yes, if you can. Adding a spare while you still have a working key is usually simpler than an all-keys-lost situation. We can do it at your home or work.
