A transponder key looks like an ordinary key, but the plastic head holds a small chip that talks to your car. When you turn the key or press the start button, the vehicle's immobilizer checks for a code it recognizes. If the code is missing or wrong, the engine may crank without starting, or not crank 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, not just the blade cut to the right shape.

In Manhattan Beach, this comes up in a few predictable ways. A spare gets lost after a day at the Strand or the pier. A key goes missing in the sand. A family realizes they have only one working key for a car that lives on a narrow walk street. Sometimes every key is gone, which is called an all-keys-lost situation, and the car cannot be driven until a new key is made and introduced to the immobilizer.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and we are fully mobile. There is no storefront to visit and no need to tow your car to us. Owner and lead technician David Shar and the team bring the equipment to you, whether you are parked at home, at work, or in a lot near Manhattan Village. This page explains how the work goes, what affects the cost, and what to expect locally.

How it works in Manhattan Beach

  1. 1

    Tell us about the vehicle

    When you call (323) 997-8867, we ask for the make, model, and year, and whether you have any working keys. We also ask whether the car uses a traditional blade key with a chip, a flip key, or a push-button start fob. That tells us what kind of programming is involved and what we need to bring.

  2. 2

    Confirm ownership

    Before we cut or program anything, we ask you to show that the vehicle is yours, typically with a matching ID and registration or title. This protects you and every other owner. We are firm about it, and a reputable locksmith should be.

  3. 3

    Cut the key if needed

    If your car uses a physical blade, we cut it by code or by decoding the lock, even when no original key exists. Many newer vehicles use laser-cut or high-security blades that need specialized cutting equipment, which we carry on the van.

  4. 4

    Program the transponder

    We connect diagnostic programming equipment to the vehicle and introduce the new key to the immobilizer. Depending on the car, this may involve adding a key to existing ones or creating a new key set when none are available. Some makes have steps that need extra time.

  5. 5

    Test everything

    Before we finish, we test the key on the door, the ignition or start button, and any remote functions that were part of the job. We also recommend having a spare made while we are there, since adding a second key is usually easier than starting from nothing again.

What affects the price

  • Vehicle make, model, and year, since some manufacturers require more involved programming procedures than others.
  • Key type: a basic chip key, a flip key, a smart key, and a push-button start fob each differ in parts and programming effort.
  • Whether you have a working key. Adding a copy is usually simpler than an all-keys-lost situation where the system must be reintroduced to a new key.
  • The blade style, because high-security laser-cut blades need different cutting equipment than standard keys.
  • The time of day and how urgent the call is, since late-night and weekend service involves different logistics than a scheduled daytime visit.
  • How many keys you want made in one visit, since doing a spare at the same time is often more efficient than a separate trip later.

Why Manhattan Beach chooses us

  • Fully mobile since 1987. We work from the vehicle, so you never need to arrange a tow to a shop.
  • Available 24/7, which matters when a key disappears after a late evening near the pier or Metlox Plaza.
  • We handle the whole job in one visit: cutting the blade, programming the chip, and testing the result.
  • We verify ownership every time. It can feel like an extra step, but it keeps your vehicle secure.
  • We are upfront about what a given car can and cannot do, and we will tell you if a dealership is the better route for a particular model.
  • We also handle the locks on your home, so one company can look after both your car keys and your front door hardware.

Transponder Key Programming across Manhattan Beach

Manhattan Beach is a compact city with a lot of cars parked in tight spaces. In the Sand Section, vehicles often sit in small garages or on narrow streets near the walk streets and the Strand, and a lost key can leave a car stuck in a spot that is hard to tow from. We come to you, so a car parked on a crowded block in ZIP code 90266 can be programmed where it stands. In the Hill Section, many households have several vehicles, and a missing key is often noticed only when the one working fob is out of reach.

Daily driving here runs along Sepulveda Blvd, Rosecrans Ave, Manhattan Beach Blvd, Aviation Blvd, and Marine Ave. If a key fails or goes missing while you are out running errands, we can meet you at the car in a parking lot at Manhattan Village or near Polliwog Park. Salt air and sand are rough on keys and fobs, and we see worn or water-damaged chips that stop communicating with the car. A fresh key programmed to the immobilizer solves that.

In the Tree Section and East Manhattan Beach, where remodels, new builds, and townhome communities are common, we also see people replacing keys while updating other household hardware. If you are managing a rental, a second home, or a vehicle belonging to a family member visiting from out of town, call (323) 997-8867 and we will explain the options for your vehicle.

Transponder Key Programming in Manhattan Beach — FAQs

What is transponder key programming?
It is the process of teaching your car's immobilizer to recognize a key's chip. The blade may open the door, but the car will not start until the chip's code is accepted by the vehicle. We do that programming on-site.
Can you come to me in Manhattan Beach?
Yes. We are fully mobile and available 24/7, so we can reach your vehicle at home, at work, or in a parking lot. Call (323) 997-8867 and tell us where the car is.
What if I lost all of my keys?
That is called all keys lost, and it is something we handle regularly. We can cut a new key and program it to the vehicle on site, after confirming ownership. It generally takes more work than adding a spare, which can affect the cost.
Why not just copy my key at a hardware store?
A hardware store can often cut a blade, but it usually cannot program the chip. The key might open the door and turn in the ignition but still fail to start the car.
Do I need to prove I own the car?
Yes. We ask for ID and proof of ownership, such as registration or title, before making a key. It is a standard security step and applies to every customer.
Can you program a push-button start fob?
In many cases, yes, depending on the make, model, and year. Tell us the vehicle details when you call (323) 997-8867 and we will say what we can do before we head out.
How is the price determined?
It depends on the vehicle, the type of key, whether you still have a working one, the blade style, and the time of day. We explain what applies to your car when you call so there are no surprises.
Should I get a spare made at the same time?
We recommend it. Adding a spare during the same visit is usually more efficient than starting from scratch after losing your only key, and it is a good idea for a car that gets used near the beach.
