A transponder key looks like an ordinary key, but inside the plastic head is a small chip that talks to your vehicle's immobilizer. If the car does not recognize the chip, the engine may turn over and then shut off, or not start at all. 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 the vehicle, and that is the work we do.

In Irwindale this comes up in a few different ways. A resident in the older single-family homes of the original townsite may have lost the only key to a family car. A driver working at one of the distribution centers, food plants, or quarry yards may have a work truck with a single key that has finally given out. Sometimes someone simply wants a spare before the last one disappears, which is almost always the easier and less stressful route.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, led by owner and lead technician David Shar. We are fully mobile. There is no storefront to visit, so you do not have to tow the car anywhere or get it to us. We bring the equipment to the parking spot, driveway, or lot where the vehicle is sitting.

How it works in Irwindale

  1. 1

    Call and describe the vehicle

    Call (323) 997-8867 and tell us the make, model, and year, where the car is, and whether you still have any working key. Whether a key survives is the biggest factor in how the job goes, so be as clear as you can.

  2. 2

    We come to you

    We are mobile and available around the clock. We drive to your location in Irwindale, whether that is a driveway in the townsite, a lot near the I-605 and Arrow Hwy interchange, or a yard off Irwindale Ave.

  3. 3

    Confirm ownership and the vehicle

    Before we begin, we ask you to show that the vehicle is yours or that you are authorized to work on it. We then confirm the exact vehicle and its immobilizer type, since the right chip and procedure depend on it.

  4. 4

    Cut or prepare the key

    If you need a new key, we cut the blade to match the vehicle's locks. The transponder chip inside the key or fob has to be compatible with your specific car, so we match it before programming.

  5. 5

    Program to the immobilizer

    Using professional programming equipment, we pair the new key with the vehicle's immobilizer. Depending on the vehicle, this may be done through the onboard diagnostic port, and some models need additional steps.

  6. 6

    Test everything before we finish

    We test the key in the door and ignition, start the engine, and check any remote buttons that come with it. If you want a spare, this is the best moment to add it, since the equipment is already connected.

What affects the price

  • Make, model, and year of the vehicle, since some immobilizer systems are more involved to program than others.
  • Whether you still have a working key. Adding a key from an existing one is usually simpler than creating one when every key is lost.
  • The type of key: a basic chip key, a flip key, a remote-head key, or a smart key and push-button fob.
  • How many keys you need programmed in one visit, including a spare.
  • Whether the blade must be cut, and how complex the cut is.
  • Time of day and location. We are available 24/7, and after-hours calls can be priced differently than daytime appointments.

  • One company for vehicle keys and for the commercial lock and gate work common across Irwindale's industrial properties.

Transponder Key Programming across Irwindale

Irwindale is a small city with a very industrial character. Most of the land is given over to gravel quarries, aggregate pits, distribution centers, and food and beverage plants, including the Huy Fong Foods plant. That means many vehicles here are work trucks and fleet cars that get heavy daily use, and a lost or worn chip key can stop a job. We can reach vehicles parked at a plant, a yard off Irwindale Ave, or a lot near the Santa Fe Dam Recreation Area on Arrow Hwy.

The residential side is much smaller, roughly 1,400 residents living in a few hundred mostly older single-family homes in the original townsite around Irwindale Ave and Los Angeles St. Many households there have held onto the same vehicles for years, and an aging key with a failing chip is common. If you live in the 91706 area, we can program a replacement or a spare right at your curb or driveway.

We also get calls from people who are only passing through. Drivers on the I-210 Foothill Freeway or the I-605, visitors to the Irwindale Speedway & Event Center, and commuters who leave a car near the Irwindale Metro A Line station may find themselves without a working key. Irwindale also shares the 91702 and 91010 ZIP codes with neighboring communities, and we serve those areas as well. Call (323) 997-8867 any hour.

Transponder Key Programming in Irwindale — FAQs

What is a transponder key?
It is a key with a small chip in the head that sends a code to your vehicle's immobilizer. If the code is not recognized, the engine will not run. Programming pairs that chip with your car.
Can you program a key if I have lost all of my keys?
In many cases, yes. It is more involved than copying from a working key, and it depends on the vehicle. Call (323) 997-8867 with the make, model, and year and we will explain what to expect.
Do I need to bring the car anywhere?
No. We are fully mobile and have no storefront. We come to your vehicle anywhere in Irwindale, whether at home, at work, or in a lot.
Is a cheap key from a hardware store or online good enough?
Not always. A key that is only cut may open the door but will not start the car unless the chip is programmed. Online keys can also have the wrong chip type, so it helps to check with us first.
Do you work on company trucks and fleet vehicles?
Yes. Irwindale has many work vehicles tied to plants, yards, and quarries. Call (323) 997-8867 and we can talk through one vehicle or several.
Are you available at night or on weekends?
Yes. We are available 24/7. Pricing can vary with timing, and we will talk it through before work begins.
Can you also program remote buttons or a smart key?
For many vehicles, yes. Remote-head keys, flip keys, and push-button smart keys vary a lot by manufacturer, so give us the vehicle details when you call.
What will I need to show you?
We ask for proof that the vehicle is yours or that you are authorized to have keys made for it, such as registration and identification. This protects owners from theft.
