A transponder key looks like an ordinary key, but inside the plastic head sits a small chip that talks to your car's immobilizer. If the car does not recognize that chip, the engine will not run, even when the blade turns the ignition perfectly. 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 your specific vehicle.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and we are fully mobile. There is no storefront to drive to, and that matters most in the situation where it counts: you have lost every key and the car cannot be driven anywhere. We bring the equipment to wherever the vehicle is parked in Tarzana, whether that is a driveway off Reseda Blvd, a medical-office garage on Ventura Blvd, or a curb in the hills.

This page explains how programming works, what affects the cost, and what to expect. We will not quote prices here, because the right answer depends on your make, model, year, and whether a working key still exists. A short call to (323) 997-8867 lets us tell you what your vehicle needs.

How it works in Tarzana

  1. 1

    Tell us about the vehicle

    When you call, we ask for the make, model, year, and whether you have any working key. We also ask where the car is parked. This tells us whether you need a spare duplicated or a key made from scratch after all keys are lost.

  2. 2

    Come to you, wherever the car is

    Because we are mobile and available 24/7, we drive to the vehicle. That could be a Tarzana-flats driveway, a hillside street south of Ventura Blvd, or a parking structure along the Boulevard. We do not ask you to tow the car to a shop first.

  3. 3

    Confirm ownership

    Before we create a key that starts a vehicle, we verify that you are the owner or authorized user. Expect to show ID and something that ties you to the car, such as registration or insurance. This protects you and anyone else who owns a car.

  4. 4

    Cut the key and prepare the chip

    If you need a new key, we cut the blade to your vehicle's code or by working from the lock itself. We then match a compatible transponder chip or smart key to your vehicle. Some vehicles need a specific key type, so we confirm that first.

  5. 5

    Program to the immobilizer

    We connect diagnostic programming equipment to the car and register the new key with the immobilizer. Depending on the vehicle, existing keys may need to be present or the system may need to be reset for an all-keys-lost situation.

  6. 6

    Test everything before we leave

    We test that the key turns the ignition, starts the engine, and operates the door locks and remote functions where applicable. If you have extra keys, we can include them in the same visit so you are not left with just one.

What affects the price

  • Make, model, and year of the vehicle, since some manufacturers use more involved immobilizer systems than others
  • Whether you still have a working key to copy from or have lost every key, which changes the programming procedure
  • The type of key: basic transponder, flip key, remote head key, or push-button smart key
  • How many keys you want programmed during the visit, including spares
  • Whether the blade must be cut from scratch, which can depend on how readily the key code can be obtained
  • Time of day and location of the vehicle, given that we serve around the clock across a wide service area

Why Tarzana chooses us

  • Fully mobile service: we come to the car, so a vehicle that will not start is not a barrier
  • In business since 1987, led by owner and lead technician David Shar
  • Available 24/7, including nights and weekends when lost keys tend to happen
  • Honest assessment up front: if your car does not need a new key or a different fix would work, we will say so
  • Ownership verification on every job, so the key we program goes only to someone entitled to the vehicle
  • Able to handle lockouts, broken keys, and rekeying too, so one call can cover related problems

Transponder Key Programming across Tarzana

Tarzana is split by Ventura Blvd, and the cars here reflect that. In the flats north of the Boulevard, residential streets near Reseda Blvd, Tampa Ave, and Lindley Ave are lined with 1950s ranch homes and apartment buildings, where street parking and shared lots are common. Key trouble there often means a lost key at an apartment complex or a spare needed before a family member borrows the car. We come to the curb or the carport and program on the spot.

South of the Boulevard, the Santa Monica Mountains hillside brings custom homes and gated estates, many with multi-car garages and newer vehicles that use push-button smart keys. Winding streets and driveway gates can make a tow impractical, so having us come up to the vehicle is much simpler. The El Caballero area, around the country club, has similar needs, and we can also program additional keys for household vehicles in one visit.

Ventura Blvd itself is a dense medical and professional corridor, including the area around Providence Cedars-Sinai Tarzana Medical Center. Staff, patients, and visitors park in garages and lots all day, and a lost or broken key can strand someone in the middle of a shift. Whether you are in ZIP 91356 or 91357, near Wilbur Ave, Corbin Ave, or just off US-101, call (323) 997-8867 and we will come to you.

Transponder Key Programming in Tarzana — FAQs

Can you program a transponder key if I have lost all my keys in Tarzana?
In most cases, yes. An all-keys-lost situation is more involved than copying from an existing key, but it is something we handle at the vehicle. Call (323) 997-8867 with your make, model, and year and we will explain what your car needs.
Do I need to tow my car to you?
No. We are fully mobile and have no storefront. We come to your vehicle, whether it is parked in a Tarzana driveway, a Ventura Blvd lot, or a hillside street.
Why did the key from the hardware store not start my car?
A cut blade can turn the lock, but the chip inside the key head must be programmed to your car's immobilizer. Without that match, the engine will not stay running or will not start at all. We can program the chip so the key works.
Can you work late at night or on weekends?
Yes, we are available 24/7. If you are stuck in Tarzana at an odd hour, call (323) 997-8867 and we will discuss your situation.
Will you need proof that the car is mine?
Yes. We verify ownership before making a key that starts a vehicle. Bring ID and registration, insurance, or other documents that connect you to the car.
What affects the cost of transponder key programming?
The main factors are the vehicle make, model, and year, the key type, whether you have a working key, and how many keys you want. We do not list prices online, but we can talk through what applies to your car by phone.
Can you program a smart key or push-button start fob?
Many smart keys and proximity fobs can be programmed, but it depends on the vehicle. Tell us what you drive when you call and we will confirm what is possible before we head out.
Should I get a spare key made while you are there?
It is usually a smart idea. Adding a spare during the same visit is typically simpler than starting over after losing your only key. Ask us about it when you call (323) 997-8867.
