If your car has a chip in the key head, the engine will not start unless the vehicle's immobilizer recognizes that chip. That is good for security, but it makes a lost, broken, or extra key more than a trip to a hardware counter. The new key has to be cut to match the lock and then introduced to the car's computer. Crenshaw Lock Company does this at your vehicle, so you never have to tow a car anywhere to get a working key.

South Gate is a car-dependent Gateway city. People here commute along the I-710, jump onto the SR-105 nearby, and run daily errands up and down Firestone Blvd, Atlantic Ave, Garfield Ave, and Imperial Hwy. When the only key goes missing, or the spare you kept in a drawer turns out not to start the car, the day stalls fast. We are fully mobile and answer around the clock, so we can meet you at home, work, or wherever the car is parked.

David Shar has run Crenshaw Lock Company since 1987, and the work has changed a great deal in that time, from simple cut keys to coded chips and push-button systems. We do not have a storefront, so everything happens on site with the tools carried in the van. We will tell you honestly what your particular vehicle needs before any work begins.

How it works in South Gate

  1. 1

    Call and describe the vehicle

    Call (323) 997-8867 and tell us the make, model, and year, and whether you have any working key. These details help us understand which type of immobilizer system the car uses and what the job involves.

  2. 2

    We come to the car

    Because we are fully mobile, a technician drives to wherever the vehicle sits, whether that is a driveway in Hollydale, a curb near South Gate Park, or a lot along Firestone Blvd. There is nothing to tow and no shop visit.

  3. 3

    Confirm ownership

    Before we cut or program anything, we ask for reasonable proof that you own the vehicle or are authorized to use it. This protects you and is standard practice for responsible locksmiths.

  4. 4

    Cut the key and prepare the chip

    If needed, we cut the blade to match your car's locks. Then we prepare the transponder chip so the vehicle's computer can accept it.

  5. 5

    Program to the immobilizer

    Using professional diagnostic equipment, we pair the new key with the car's immobilizer. Depending on the vehicle, this may involve reading the system and adding a key, even when no original is available.

  6. 6

    Test everything

    We start the engine, then check the door locks and any remote functions on the key. You see it working before we finish, and we can program additional keys at the same visit so you have a spare.

What affects the price

  • The 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 or all keys are lost, which changes how the system must be accessed.
  • The type of key itself: a basic chip key, a flip key, a smart or push-button fob, or one with a laser-cut blade.
  • How many keys you need programmed during the same visit.
  • Time of day and where the vehicle is located, since we answer 24/7 and travel to you.
  • Whether blade cutting or a lock repair is also needed on top of the programming.

Transponder Key Programming across South Gate

South Gate drivers rely on their cars. A typical day might mean the I-710 toward Long Beach, a run on Firestone Blvd, or a stop at the Azalea Regional Shopping Center. When a chip key fails in a parking lot there, a mobile locksmith is more practical than arranging a tow. We work throughout ZIP code 90280 and the surrounding area.

In Hollydale, many homes are 1940s and 1950s single-family houses with driveways and street parking. We often meet customers at these homes when a spare key turns out not to be programmed, or when the only key was lost around the house. Along the Tweedy Mile business district on Tweedy Blvd, shop owners and employees sometimes need a work vehicle key fixed without leaving the business unattended, and we can come to them.

We also serve people near South Gate Park and Hollydale Park, along Atlantic Ave and Garfield Ave, and on Imperial Hwy. Call (323) 997-8867 at any hour and we will arrange to come to you. As the same local company that can also handle home and business locks, we can address other lock needs while we are there.

Transponder Key Programming in South Gate — FAQs

What is a transponder key?
It is a car key with a small chip inside the head. The chip sends a code to the vehicle's immobilizer, and the engine will only run if the code matches. Programming pairs a new key with that system.
Can you program a key if I lost all my keys in South Gate?
In many cases, yes. Even without a working key, we can usually access the vehicle's system, cut a new key, and program it. Call (323) 997-8867 with your vehicle details and we will tell you what to expect.
Do I need to tow my car to you?
No. We are fully mobile and have no storefront. We drive to your car wherever it is parked in South Gate and do the work there.
Are you available at night or on weekends?
Yes. We answer 24/7. Call (323) 997-8867 any time and we will arrange service.
Will I need to show proof of ownership?
Yes. We ask for reasonable proof that you own the vehicle or are authorized to have a key made. It protects you and is a normal part of responsible locksmith work.
Can you make a spare key at the same visit?
Yes. Having a spare programmed while we are already there is often easier than dealing with a total key loss later. Let us know how many keys you want.
Why not just get a cheaper key cut at a hardware store?
A copied blade may open the door, but without a programmed chip the engine will not start on most chip-key vehicles. The chip must be paired with the immobilizer, which takes diagnostic equipment.
How is the price determined?
It depends on the vehicle, the type of key, whether any key still works, how many keys you need, and when and where we come out. We discuss these factors with you before starting.
