Most cars built since the late 1990s 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 must recognize that chip before the engine will run. If you have lost your only key, snapped one off, or want a spare before something goes wrong, the new key has to be cut and then programmed to your specific vehicle.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and David Shar, our owner and lead technician, built the business on mobile service. We are fully mobile. There is no storefront to visit, and you do not need to tow your car anywhere. We bring the key cutting and programming equipment to wherever the vehicle is parked in Port Hueneme, at any hour.

That matters in a small coastal city like this one. Whether your car is parked on a Surfside street, in a lot near the Port of Hueneme, or at a driveway near the base, getting a programmed key on site avoids a tow and a dealership wait. Programming is only part of the job, though. We also confirm the key turns the ignition and the remote functions work before we leave.

How it works in Port Hueneme

  1. 1

    Call and describe the vehicle

    Call (323) 997-8867 any time of day or night. Tell us the make, model, and year, and whether you still have a working key. That tells us whether this is an added spare or an all-keys-lost situation, which are handled differently.

  2. 2

    We travel to your location

    Because we are fully mobile, we come to you in Port Hueneme, whether you are at home, at work, or stuck in a parking lot. We make no promises about timing over the phone, but we will keep you informed.

  3. 3

    Verify ownership

    Before making a key for a vehicle, we ask for identification and proof that the car is yours, such as registration or title. This protects you and prevents keys from being made for vehicles that are not the requester's.

  4. 4

    Cut the key or blade

    We cut the new key to your vehicle's code or by decoding the lock. If your car uses a laser-cut or high-security blade, we use the appropriate cutting equipment. Some vehicles use a push-button or proximity fob instead of a blade.

  5. 5

    Program the transponder

    We connect diagnostic programming equipment to the vehicle and register the new chip with the immobilizer. Depending on the vehicle, this may also involve pairing remote buttons.

  6. 6

    Test everything

    We start the engine with the new key, test lock and unlock functions, and check every key you hand us, including the existing ones, so you are not surprised later.

What affects the price

  • Vehicle make, model, and year, since some manufacturers use more complex immobilizer systems than others
  • Key type: a basic transponder chip key, a remote-head key, a flip key, or a proximity smart key
  • Whether you still have a working key (adding a spare) or have lost all keys, which requires more work
  • Blade style, such as a standard cut versus a laser-cut high-security blade
  • Whether remote buttons need to be paired in addition to the chip
  • Time of day and location of the vehicle, given that we serve around the clock

  • We verify ownership before making keys, which protects you from misuse

  • Honest conversation up front about what your particular vehicle needs, including when a dealer is the only option

Transponder Key Programming across Port Hueneme

Port Hueneme is a compact city wrapped around Naval Base Ventura County, and vehicles here see a lot of coastal wear. Residents of Surfside, Bubbling Springs, and the Hueneme Beach and Downtown area park along narrow streets, in condo garages, and in apartment lots, and salt air can be hard on key fobs and ignition components. If a key has worn, cracked, or stopped responding, it is worth getting a spare programmed before it fails completely. We serve ZIP codes 93041, 93043, and 93044.

Base personnel, Seabees, port workers, and families who come to Hueneme Beach Park & Pier or the U.S. Navy Seabee Museum sometimes lose keys far from home. If you are stuck near Port Hueneme Rd, Ventura Rd, Hueneme Rd, or Channel Islands Blvd, we can come to the vehicle instead of asking you to arrange a tow.

Since we are mobile only, you will not find a shop on a corner here, but you will find us on the road across Ventura County. Call (323) 997-8867 and we will talk through your car and your situation.

Transponder Key Programming in Port Hueneme — FAQs

Can you program a transponder key in Port Hueneme at night?
Yes. We are available 24/7 and fully mobile, so we can come to your vehicle in Port Hueneme at any hour. Call (323) 997-8867.
What if I lost all my keys?
An all-keys-lost situation is common and can usually be handled on site. We cut a new key and program it to the immobilizer. Call (323) 997-8867 and tell us the make, model, and year.
Do I need to tow my car to you?
No. We are mobile only and bring the equipment to wherever the car is parked, whether it is at home in Surfside, at work, or on the street.
Will you need proof that the car is mine?
Yes. We ask for identification and proof of ownership, such as registration or title, before making a key. This is a standard safeguard.
Is programming cheaper than going to the dealership?
We do not quote prices here, since cost depends on the vehicle and key type. Many owners find mobile service convenient because there is no tow and no trip to a dealer. Call us to discuss your vehicle.
Can you program a key I bought online?
Often, yes, if the key is compatible with your vehicle. Compatibility varies, so let us know the details when you call so we can tell you what is likely to work.
Can you also program the remote buttons?
In many cases, yes. Remote-head keys and fobs can often be paired during the same visit, depending on the vehicle.
Does salt air affect transponder keys?
Coastal moisture and salt can wear on key shells, blades, and buttons over time, although the chip itself is usually protected. If your key is worn, a spare is a good idea. Call (323) 997-8867 to ask.
