A transponder key looks like an ordinary key, but inside the plastic head is a small chip that talks to your car's immobilizer. If the car doesn't recognize that chip, the engine will not start, even when the blade turns the ignition. That is why a duplicate from a hardware counter often fails: it opens the door but will not run the car. Programming has to match the chip to the vehicle's computer.

In Beverly Hills, the need tends to show up in specific ways. A valet at a Wilshire Blvd restaurant hands back one key and the spare is at home. A resident in the hills realizes the only key to a European sedan went missing after a weekend. A family with a garage full of cars wants a spare for each one before something goes wrong. In each case, driving to a dealership or having the car towed is a hassle we can often avoid, because we are fully mobile.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, led by owner and lead technician David Shar. We work 24/7, and we bring the equipment to wherever the vehicle is parked, whether that is a driveway behind a gate, a condo garage, or the curb on Canon Dr. Because every make and model is different, we will tell you honestly what your particular vehicle needs before we start.

How it works in Beverly Hills

  1. 1

    Call and describe the situation

    Call (323) 997-8867 and tell us the make, model, and year, and whether you have a working key, a spare, or none at all. That determines whether we are adding a key or starting from scratch, and it helps us bring the right blanks and equipment.

  2. 2

    We come to your vehicle

    We are mobile only, so we drive to you. That could be a home garage in The Flats, a hillside driveway off Benedict Canyon Dr, or a parking structure in the Golden Triangle. We ask for access to the car and the vehicle's ownership information.

  3. 3

    Verify ownership

    Before we create a key for any vehicle, we confirm you are entitled to it. Expect to show identification and proof of ownership or registration. This protects you and is standard practice for responsible locksmiths.

  4. 4

    Cut the key and prepare the chip

    We cut the blade to match your vehicle's locks, or, for keys with an emergency blade, prepare the key as needed. For lost-key situations, we can generate a key from the vehicle's lock information rather than a working original.

  5. 5

    Program to the immobilizer

    Using diagnostic equipment, we connect to the car and register the new transponder with its immobilizer system. Depending on the vehicle, this may also involve erasing a lost key so it can no longer start the car.

  6. 6

    Test everything before we leave

    We confirm the key turns the ignition, starts the engine, and operates the door locks, and we test any remote buttons. We make sure each key works before we consider the job done.

What affects the price

  • Make, model, and year: some vehicles accept simple on-board programming, while many European and newer models need more advanced equipment and procedures.
  • Whether you have a working key: adding a copy from an existing key is usually simpler than creating a key when all keys are lost.
  • Key type: a basic chip key, a remote-head key, a flip key, and a smart or proximity key each involve different parts and programming steps.
  • Number of keys needed: programming several keys in one visit differs from a single spare.
  • Time of day and location: after-hours calls and hard-to-reach locations can affect the overall quote.
  • Extra work: if a key is broken in the ignition or the lock needs repair, that adds to the job.

Why Beverly Hills chooses us

  • Fully mobile since 1987: we bring the work to your car instead of asking you to tow it or find a ride to a shop.
  • Owner-led experience: David Shar leads the business, so the knowledge behind the work is not just a rotating call center.
  • Available 24/7: lost keys do not wait for business hours, and neither do we.
  • Honest assessment first: if your vehicle really requires dealer-only service, we will say so rather than start a job we cannot finish.
  • Ownership verification on every job: we check before we make a key, which protects you from someone else getting access to your vehicle.
  • Comfortable with high-end vehicles: Beverly Hills garages hold a wide range of makes, and we explain what each one needs in plain terms.

Transponder Key Programming across Beverly Hills

Beverly Hills is a car-heavy city in a compact space. In The Flats, many homes have long driveways and detached garages, and vehicles are often parked behind gates. In Trousdale Estates and the hillside pockets around Benedict Canyon Dr and Coldwater Canyon Dr, steep, winding streets make a tow truck a poor first choice, so a mobile technician who comes to the car makes practical sense. Some of those properties also have keypad or intercom driveway gates, which we understand and work around when reaching your vehicle.

On the commercial side, the Golden Triangle, Rodeo Drive, and the stretch of Wilshire Blvd near the Beverly Wilshire put a lot of cars through valet service. Keys get separated, left in jackets, or misplaced after dinner or a hotel stay. If you are parked near The Beverly Hills Hotel or on Sunset Blvd and find yourself without a working key, we can meet you where the car sits, whether that is a garage level or a quiet side street.

We serve all of Beverly Hills, including ZIP codes 90210, 90211, and 90212, along with surrounding Greater Los Angeles. Whether you are near Will Rogers Memorial Park, close to Greystone Mansion, or along Santa Monica Blvd, call (323) 997-8867 and we will talk through the situation and what your car requires.

Transponder Key Programming in Beverly Hills — FAQs

What is a transponder key?
It is a key with a small chip in the head that sends a code to your car's immobilizer. If the code matches, the engine can start. Without it, the car may turn over but will not run.
Can you program a transponder key if I lost all my keys in Beverly Hills?
In many cases yes. We can often create and program a new key even when no working key exists, though the process depends on the vehicle. Call (323) 997-8867 with your make, model, and year, and we will tell you what to expect.
Do I need to tow my car to you?
No. We are fully mobile and there is no storefront to visit. We come to your car, whether it is in a driveway, a condo garage, or on the street.
Is the service really available 24/7?
Yes. We take calls day and night. If you are stranded late at night after dinner in the Golden Triangle or locked out at home, call (323) 997-8867.
Why can't I just get a copy cut at a hardware store?
A cut blade alone usually will not start a transponder car. The chip must be programmed to your vehicle's immobilizer, which takes diagnostic equipment. A cut-only copy might open the door but not run the engine.
Do you need proof that the car is mine?
Yes. We verify ownership before making a key, usually with identification and registration or title. It is a safeguard for you and for us.
Can you work on luxury and European vehicles?
We work on a wide range of makes, and many Beverly Hills vehicles fall in that category. Some newer or specialized models have tighter requirements, so we will give you an honest answer about what can be done on site.
How is the price determined?
It depends on the vehicle, the type of key, how many keys you need, whether any working key exists, and when and where the work happens. We discuss these factors up front. Call (323) 997-8867 to get started.
