A transponder key looks like an ordinary key, but inside the plastic head is a small chip that talks to your car's immobilizer. If the chip is not recognized, the engine may crank without starting or not turn over at all, even when the metal blade turns the ignition perfectly. Programming is the step that teaches the car to accept a new key, and it is the part a hardware-store duplicate cannot do.

In North Hills, this need tends to show up at ordinary moments: the only key is lost in the parking lot of a Nordhoff Street shop, a spare never got made and the one key finally fails, or a used car was bought with a single key and no backup. Because we are fully mobile, there is no shop to tow the car to. The work happens where the vehicle is parked, whether that is a driveway, an apartment carport, or a curb near the Sepulveda Basin.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and owner and lead technician David Shar built the business on straightforward, explained work. This page covers how transponder programming works, what affects the cost, and what to expect if you call from North Hills.

How it works in North Hills

  1. 1

    You call and describe the situation

    Call (323) 997-8867 any hour. Tell us the make, model, and year, where the car is in North Hills, and whether you still have a working key or have lost every key. That tells us which type of job it is, since adding a spare differs from replacing all keys.

  2. 2

    We confirm ownership

    Before cutting or programming anything, we ask for proof that the vehicle is yours, typically photo ID along with registration or title. This protects you and is standard responsible practice for any vehicle key work.

  3. 3

    We come to your vehicle

    Our technician drives to the car with the key blanks and programming equipment needed. There is no storefront visit and no towing. If the car is at an apartment building, a work lot, or on a residential street, we work there.

  4. 4

    Key is cut and the chip is prepared

    If you need a new blade, we cut it to the vehicle's code or from the lock itself. The transponder chip is then matched to your vehicle's system so it is ready to be introduced to the immobilizer.

  5. 5

    Programming to the immobilizer

    We connect to the car's diagnostic system and register the new key. Depending on the vehicle, existing keys may need to be re-registered at the same time. This is why a car can behave differently from another of the same brand.

  6. 6

    Testing before we leave

    We test that the key turns the ignition, starts the engine, and operates any remote functions it is meant to. You see it work before the job is finished, and we point out anything worth knowing about spare keys.

What affects the price

  • Make, model, and year of the vehicle, since some immobilizer systems are far more involved to program than others.
  • Whether you still have a working key to copy or all keys are lost, which changes the amount of work required.
  • The type of key: a basic chip key, a remote-head key, or a push-button smart key each involve different parts and procedures.
  • Whether a new blade must be cut or the original lock needs attention along with the programming.
  • How many keys you want programmed in one visit, as adding a spare while we are already there is usually more efficient than a separate trip.
  • Time and location of the call, including after-hours service, since we are available around the clock.

Why North Hills chooses us

  • Fully mobile service, so your car does not need to be towed or driven with a failing key. We bring the work to you.
  • Available 24/7, which matters when a key fails late at night or early before a commute down the 405.
  • In business since 1987, with owner David Shar involved as lead technician rather than a call center relaying jobs.
  • Ownership is verified before we program keys, and we explain why, rather than skipping a step that protects your vehicle.
  • We test the key fully before leaving, and we will tell you plainly if a vehicle needs something beyond what we can do on site.
  • We also handle the locks around your life, from apartment rekeys to storefront hardware, so one number covers many needs.

Transponder Key Programming across North Hills

North Hills, ZIP 91343, is a car-dependent part of the San Fernando Valley, and residents rely on Nordhoff Street, Roscoe Boulevard, Sepulveda Boulevard, Devonshire Street, and the I-405 for daily trips. When a transponder key stops working, getting to work, school, or a medical appointment can stall quickly. We serve both North Hills West and North Hills East, so the whole community is covered.

In North Hills West, many homes are 1950s and 1960s single-family tract houses with driveways and garages, so cars are often parked at home and a technician can work right there. In North Hills East, denser dingbat and garden-apartment buildings mean many people park in carports or shared lots, and tenant turnover can leave a household with a single key for a shared vehicle. We are comfortable working in either setting.

People also lose keys near the places that draw them out: a walk at the Sepulveda Basin Recreation Area, a visit to North Hills Community Park, an appointment at the VA Sepulveda Ambulatory Care Center, or a day on the campus of California State University, Northridge, just over the line in Northridge. Wherever the car is parked, call (323) 997-8867 and we will come to you.

Transponder Key Programming in North Hills — FAQs

Can you program a transponder key if I lost all my keys in North Hills?
In many cases, yes. All-keys-lost jobs take more work than adding a spare, but we can often cut and program a new key at your vehicle. Call (323) 997-8867 with the make, model, and year so we can tell you what to expect.
Do I need to tow my car to you?
No. We are fully mobile and there is no storefront to visit. We bring the equipment to wherever the car is parked, whether in a driveway, apartment carport, or on the street.
Why can't I just copy my key at a hardware store?
A hardware-store copy cuts the metal blade but does not program the chip. If the immobilizer does not recognize the chip, the engine will not start even if the blade turns the ignition.
Will you work at night or on weekends?
Yes, we are available 24/7. If your key fails late at night or on a weekend, call (323) 997-8867 and we will arrange service.
What do I need to show to prove the car is mine?
We typically ask for photo ID and vehicle registration or title. Verifying ownership is a normal and necessary step before any vehicle key is cut or programmed.
Is it smart to make a spare while I still have a working key?
Usually, yes. Copying from a working key is generally less involved than an all-keys-lost situation, and a spare saves you from a stressful call later. Ask us about it when you phone.
Do you program remote and push-button keys too?
We work on a range of key types, including chip keys, remote-head keys, and many smart keys, though support varies by vehicle. Give us your vehicle details at (323) 997-8867 and we will confirm.
How is the price determined?
It depends on the vehicle, the type of key, whether you have a working key, how many keys you need, and when you call. We do not quote prices on this page, but we will explain the factors when you contact us.
