A transponder key looks like an ordinary key, but its plastic head holds a small chip that talks to your car's immobilizer. If the chip's code isn't recognized, the engine may crank without starting, or won't crank at all. That is why a hardware-store copy often opens the door but won't start the car. Programming is the step that introduces a new key to the vehicle's computer.

In Marina del Rey, this need tends to show up in particular ways. Many residents live in dense waterfront complexes with assigned garage spaces. Others park along Admiralty Way or near Fisherman's Village while spending a day on the water. A lost key, a single remaining key, or a cracked key head can all leave someone stuck far from a dealership, and often with a car that can't be driven to one.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and we are fully mobile. There is no storefront to visit. David Shar and our technicians bring the equipment to you, 24 hours a day, so the work happens in your parking space instead of on a tow truck or in a waiting room.

How it works in Marina del Rey

  1. 1

    Call and describe the situation

    Phone (323) 997-8867 and tell us the make, model, and year of the vehicle, how many working keys you have (including zero), and where the car is parked. This helps us bring the right blank and programming tools.

  2. 2

    Confirm ownership

    Before we make or program a key, we ask for proof that the vehicle is yours, such as registration and matching photo ID. This protects you and is a standard part of responsible automotive locksmith work.

  3. 3

    Identify the key and immobilizer type

    We check the vehicle's system to determine what kind of chip, key blade, or remote it needs. Some vehicles accept an additional key when a working one is present, while others need a different procedure if all keys are lost.

  4. 4

    Cut or prepare the key

    If you need a new physical key, we cut it to match the vehicle's code or lock. A mobile setup means this happens at the car, so you can test the key in the door and ignition right away.

  5. 5

    Program to the vehicle

    We connect our programming equipment to the vehicle and register the new transponder with the immobilizer. Depending on the car, we may also be able to remove a lost key from the system.

  6. 6

    Test everything before we leave

    We confirm the key unlocks the door, starts the engine, and operates any remote functions it is meant to handle. You get the chance to try it yourself before we finish.

What affects the price

  • Make, model, and year of the vehicle, since immobilizer systems vary widely between manufacturers.
  • Whether you still have a working key to copy or all keys are lost, which changes the programming method.
  • The type of key: a basic chip key, a flip key, a remote head key, or a smart or proximity key.
  • Whether the key blade must be cut, and whether it is a standard edge-cut or a laser-cut style.
  • Time of day and the vehicle's location, since we are available 24/7 and travel to you.
  • Number of keys you need programmed in one visit.

Why Marina del Rey chooses us

  • Fully mobile service: we come to your marina parking space, apartment garage, or driveway rather than asking you to tow the car.
  • Serving the region since 1987, with an owner-led approach under David Shar.
  • 24/7 availability for lost-key emergencies, including evenings after a day at the harbor.
  • We discuss the factors that affect cost before starting work, and we don't pad the conversation with vague promises.
  • Familiarity with Marina del Rey's gated, garage-heavy living, where access and parking logistics matter as much as the key itself.
  • Ownership verification on every job, which keeps your vehicle from being keyed up for the wrong person.

Transponder Key Programming across Marina del Rey

Marina del Rey is a compact, water-oriented community, and cars here live in a particular environment. Many residents in Mariners Village and along the Admiralty Way and Via Marina apartment corridor park in large shared garages or gated lots built in the 1970s and 80s. If you lose a key in one of these complexes, we can meet you at the car, though a gate code, guest access, or a call to property management may help us get in smoothly.

Salt air and humidity are a fact of life near the boat basins, and they are hard on keys, key fobs, and the batteries inside them. A fob that has been in a pocket on a dock or beside Mother's Beach may stop responding even though the chip is fine. We can look at whether the key needs reprogramming, a new shell, or simply a replacement.

We also serve the Silver Strand and Marina Peninsula, where many addresses carry a Marina del Rey mailing address in ZIP 90292 or 90295 even though they fall administratively under the City of LA and Venice. Whether you are parked near Burton Chace Park, Waterside and Marina Marketplace, or off Lincoln Boulevard, Washington Boulevard, or Culver Boulevard, call (323) 997-8867 and we will come to you.

Transponder Key Programming in Marina del Rey — FAQs

What is transponder key programming?
It is the process of registering a key's embedded chip with your vehicle's immobilizer so the engine will start. Without this step, even a perfectly cut key usually will not run the car.
Can you program a key if I have lost all my keys?
In many cases yes, though the method depends on the vehicle. Call (323) 997-8867 with the make, model, and year, and we can tell you what to expect.
Do you come to the marina or my apartment garage?
Yes. We are fully mobile and serve Marina del Rey, including Mariners Village, the Admiralty Way and Via Marina corridor, and the Silver Strand. We come to the vehicle, so you do not need to tow it.
Is it cheaper than going to a dealership?
We can't promise a comparison for every vehicle, since it depends on the car and key type. What we can say is that mobile service saves you the tow and the trip. Call (323) 997-8867 to discuss your situation.
What do I need to show you?
We ask for proof of ownership, typically registration or title and a matching photo ID, before making or programming a key. It is a security step that protects you.
Will my old lost key still work after I get a new one?
On many vehicles we can erase lost keys from the immobilizer during programming, so a missing key can no longer start the car. Ask us when you call and we will explain what your vehicle allows.
Can salt air damage my key or fob?
Moisture and salt can corrode battery contacts and wear down plastic shells and buttons. If your fob has become unreliable after time near the water, a battery or shell replacement may solve it, and we can check whether reprogramming is also needed.
Are you available at night or on weekends?
Yes, we are available 24/7. If you are locked out or stranded at the harbor late at night, call (323) 997-8867.
