A transponder key looks like an ordinary key, but the plastic head holds a small chip that talks to your car. When you turn the ignition, the vehicle's immobilizer checks for the right code. If the chip is missing, unregistered, or damaged, the engine may crank without starting, or not crank at all. Programming is the step that introduces a new key to the car, and it is a different job from cutting the metal blade.

In Mission Hills, we often get these calls from people who have just lost their only key, or who are down to one worn key and want a spare before it fails. Some calls come from residents who bought a used car with a single key. Others come from visitors to the Mission San Fernando Rey de Espana or the medical offices near Providence Holy Cross Medical Center, who find a key missing after a long day. Because Crenshaw Lock Company is fully mobile, we bring the equipment to wherever the car is parked. There is no shop to tow it to, and no storefront to visit.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and David Shar, our owner and lead technician, has seen the industry move from simple metal keys to chip keys and push-button systems. We will tell you plainly what your vehicle needs, including cases where a dealer is the only practical route. Call (323) 997-8867 at any hour.

How it works in Mission Hills

  1. 1

    Call and describe the situation

    Tell us the year, make, and model of the vehicle, how many working keys you have, and where the car is. A car with a working key is usually a simpler job than an all-keys-lost one. We will explain what we can do and what to expect before anyone drives out to you.

  2. 2

    We come to your vehicle

    We are 24/7 and fully mobile, so we meet you where the car sits, whether that is a driveway on a quiet residential street, a lot along Sepulveda Boulevard, or a parking space near the medical offices. You do not need to tow it anywhere.

  3. 3

    Verify ownership

    Before we create a key for any vehicle, we ask for reasonable proof that you own it or are authorized to have it keyed. This protects you and protects every other vehicle owner.

  4. 4

    Cut or prepare the key

    If the key needs a blade, we cut it to match your lock. If you already have a compatible chip key or fob, we check that it can be used with your vehicle before we begin programming.

  5. 5

    Program to the immobilizer

    We connect professional programming equipment to the car and register the new key with the immobilizer. Depending on the vehicle, this can include adding a spare alongside existing keys or creating the first key when none are left.

  6. 6

    Test everything

    We test the key in the door, the ignition, and any remote functions it should have. We also confirm that the car starts and keeps running, so you leave with keys you can trust.

What affects the price

  • Vehicle make, model, and year, since some systems are far more involved to program than others.
  • Whether you have a working key or all keys are lost, which changes the steps required.
  • The type of key: a basic transponder key, a flip key, a remote head key, or a push-button proximity fob.
  • Whether the key blade needs to be cut, including laser-cut or high-security styles.
  • Whether the key or fob is supplied by you or sourced by us, and how available it is for your vehicle.
  • The time of day and the location of the vehicle, since we serve you 24/7 and travel to you.

Why Mission Hills chooses us

  • Fully mobile service: we bring the programming equipment to your car, so you avoid towing and dealership waits.
  • In business since 1987, with an owner-operator, David Shar, who is directly involved in the work.
  • Straight answers about limits: if your vehicle needs dealer-level work, we say so rather than promise what we cannot do.
  • One call covers the blade, the chip, and the programming, so you are not shuttled between a key cutter and a programmer.
  • Available 24/7, which matters when a lost key strands you late at night or early in the morning.
  • We test the finished key in the door, ignition, and remote functions before we leave.

Transponder Key Programming across Mission Hills

Mission Hills is one of the older parts of the San Fernando Valley, centered on the Historic Mission district and Mission San Fernando Rey de Espana. Many homes here are late-1940s to 1960s single-family houses, with driveways and street parking on quiet blocks, including the historic Dennis Park tract. That means a lot of cars get parked outside overnight, and a lost key or a dead chip key often turns up first thing in the morning. We can come to the driveway in 91345 and program the key right there.

The area's roads shape where calls come from. Drivers use Sepulveda Boulevard, San Fernando Mission Boulevard, and Brand Boulevard daily, and CA-118 (Ronald Reagan Fwy) is close by for commuters. If you are stuck in a lot on the Sepulveda Boulevard corridor, we can meet you there. Staff and visitors around Providence Holy Cross Medical Center, as well as people who stop at the Andres Pico Adobe or the San Fernando Mission Cemetery, sometimes realize a key is missing far from home, and we can work in that kind of lot too.

Because we are mobile only, there is no shop to visit. Call (323) 997-8867, give us your vehicle details and cross streets, and we will tell you how we can help.

Transponder Key Programming in Mission Hills — 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. The metal blade may open the door, but without a matching chip the car will usually not run. Call (323) 997-8867 to ask about your vehicle.
Can you come to me in Mission Hills?
Yes. We are fully mobile and available 24/7, so we can meet you at your home, at work, or in a parking lot near Sepulveda Boulevard or the medical offices. We have no storefront, because we come to you.
I lost all my keys. Can you still make a new one?
In many cases, yes. All-keys-lost situations take more steps than adding a spare, but we can often cut and program a new key on-site. Some vehicles are limited, and we will tell you honestly. Call (323) 997-8867 with your vehicle details.
Is it better to get a spare before I lose my only key?
Usually yes. Adding a spare while you still have a working key is typically simpler than starting from nothing, and it means you are not stranded if the one key fails or goes missing.
Do I need to prove I own the car?
Yes. We ask for reasonable proof of ownership or authorization before making a key. It protects you, and it keeps keys from being made for vehicles by people who should not have them.
Will my programmed key include the remote buttons?
It depends on the key type. Some keys only start the car, while remote head keys and fobs add lock and unlock buttons. We can discuss the options for your vehicle when you call.
Why does the price vary from car to car?
Cost depends on the make, model, and year, the type of key, whether you have a working key, and whether the blade must be cut. We explain these factors when you describe your vehicle.
Can a dealer do this instead?
A dealer can program keys, but it often means getting the car to them, and some owners find that inconvenient. We come to you instead. If your vehicle truly needs dealer-level work, we will say so.
