Most vehicles built in the last couple of decades will not start with a plain metal key. Inside the plastic head of the key is a small transponder chip, and the vehicle's immobilizer checks that chip before it lets the engine run. If you have lost your only key, snapped one, or just want a spare before something goes wrong, the new key has to be cut where required and then programmed to the car. That is what transponder key programming means, and it is the heart of what we do for drivers here.

Santa Fe Springs is a working city. Between the warehouses, distribution yards and manufacturing plants, there are a lot of delivery vans, box trucks, work pickups and commuter cars that live and sleep around I-5, I-605, Telegraph Rd, Imperial Hwy and Norwalk Blvd. A lost key in this setting is rarely a small problem. It can sideline a vehicle that is supposed to be on a route, or leave someone stranded in a parking lot after a shift. Because Crenshaw Lock Company is fully mobile, we bring the equipment to wherever the vehicle is parked rather than asking you to tow it anywhere.

David Shar has led this business since 1987, and the work has changed a great deal in that time, from simple cut keys to chip keys and push-button systems. We explain what your vehicle needs before we start, and we tell you plainly if a particular make or model calls for a different approach. There is no storefront to visit; we are a mobile service, available around the clock.

How it works in Santa Fe Springs

  1. 1

    Call and describe the vehicle

    Phone (323) 997-8867 and tell us the make, model and year, and whether you have any working key. Whether you need a spare or have lost every key changes the approach, so we sort that out first.

  2. 2

    We come to you

    We are fully mobile and available 24/7. We meet you at your home, workplace, fleet yard or wherever the vehicle is parked, so there is nothing to tow and no shop to find.

  3. 3

    Verify ownership

    Before creating a key for any vehicle, we ask for reasonable proof that you are the owner or authorized to have access. This protects you and protects the vehicle.

  4. 4

    Cut the key if needed

    If the key has a physical blade, we cut it to match the vehicle's lock, using the door or ignition as a reference when no original key exists. Some push-start fobs have no blade to cut.

  5. 5

    Program to the immobilizer

    We connect programming equipment to the vehicle and register the new transponder or fob so the immobilizer recognizes it. Where the vehicle allows it, we can also remove lost keys from memory so they no longer start the car.

  6. 6

    Test everything

    Before we finish, we confirm the key turns the lock, starts the engine and, where applicable, operates the remote functions. For fleets, we label and check each duplicate so nothing is left uncertain.

What affects the price

  • Make, model and year of the vehicle, since immobilizer systems differ widely between manufacturers.
  • Whether you have a working key to copy from or have lost every key, which affects how much work is involved.
  • The type of key: a basic transponder key, a remote head key, a flip key or a push-button smart fob.
  • How many keys you need, which matters for fleet duplicates at a distribution yard.
  • Whether the key blade needs to be cut, including laser-cut or high-security blades.
  • Time of day and location, since we are available 24/7 and travel to you throughout the service area.

Why Santa Fe Springs chooses us

  • Fully mobile service: we bring cutting and programming equipment to your vehicle, so you never have to tow a car to be rekeyed.
  • Open 24/7, which suits shift workers and drivers in the logistics corridor who cannot wait for business hours.
  • Locksmithing experience since 1987 under owner and lead technician David Shar, covering both older mechanical keys and modern chip systems.
  • We understand fleet needs, including duplicate keys for multiple vehicles and resolving a locked truck during a working shift.
  • We explain options and limits honestly, including when a vehicle needs something different, rather than promising what the car cannot do.
  • Ownership verification on every job, so a new key is only made for someone entitled to it.

Transponder Key Programming across Santa Fe Springs

Santa Fe Springs mixes industry with older residential pockets, and vehicle key problems show up in both. In the Santa Fe Springs Industrial District along the Telegraph Rd and Shoemaker Ave corridor, fleets of vans and trucks sit in distribution yards, and a lost or damaged key can interrupt a route. We can program duplicate transponder keys on site and help when a truck is locked during a shift. Many of these businesses also need commercial lock work, which we handle as well.

In the Los Nietos area, with its modest post-war single-family homes, the more typical call is a household that has lost the only key to a family car or wants a spare before the last one fails. Driveways and street parking there make a mobile visit convenient, and we can program the key right at the curb. Around the Heritage Park district, we also help drivers whose key stopped working after a battery change or a bad fall.

We serve ZIP codes 90670 and 90671, and drivers who get stranded near the Santa Fe Springs Swap Meet, Town Center Hall, the Clarke Estate on Pioneer Blvd, or along Imperial Hwy and Norwalk Blvd. Wherever you are parked in the city, call (323) 997-8867 at any hour.

Transponder Key Programming in Santa Fe Springs — FAQs

Do you offer transponder key programming in Santa Fe Springs at night?
Yes. We are available 24/7 and fully mobile, so we can come to your vehicle in Santa Fe Springs at any hour. Call (323) 997-8867 and we will talk through what you need.
What is a transponder key?
It is a key with a small chip in its head. The vehicle's immobilizer reads the chip and only allows the engine to start if it recognizes the code. A key with the right blade but no programmed chip may open the door but will not start the car.
I lost all my keys. Can you still make a new one?
In many cases, yes. We can cut a key from the vehicle and program a new one to the immobilizer, depending on the make and model. We verify ownership first. Call (323) 997-8867 with your vehicle details and we will explain what is possible.
Can you make duplicate keys for a delivery fleet?
Yes. We can program multiple transponder keys for vehicles at a yard, such as those along Shoemaker Ave. Tell us how many vehicles and keys you need when you call so we can plan the visit.
Do I need to tow my car to you?
No. We are mobile only and have no storefront. We bring the equipment to your car, whether it is at home in Los Nietos, at work, or in a parking lot.
Will you ask for proof that the vehicle is mine?
Yes. We ask for reasonable proof of ownership or authorization before making a key. It is a standard safeguard for our customers and for the vehicle.
Can a lost key be removed so it no longer starts the car?
On many vehicles, the programming process lets us erase old keys from the immobilizer memory so a lost key will not work. This depends on the vehicle, so ask when you call (323) 997-8867.
What affects the cost of programming a transponder key?
The main factors are the vehicle's make, model and year, the type of key or fob, how many keys you need, whether any key still exists, and whether the blade must be cut. We discuss these with you before work begins.
