Losing a car key is stressful anywhere, but in San Marino it tends to happen in very particular places: a parking spot after a morning at the Huntington, a quiet stretch beside Lacy Park, a driveway behind a gated estate, or a spot along Huntington Drive. Whatever the setting, you need a key that works and a technician who comes to you rather than asking you to tow a vehicle somewhere.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, led by owner and lead technician David Shar. We are 24/7 and fully mobile. There is no storefront to visit; our equipment travels in our vehicles, so key cutting and programming happen right where your car is parked.

This page explains how car key replacement works, what affects the price, and what is specific to San Marino, a residential city where many households own several vehicles and want the job done discreetly and correctly the first time.

How it works in San Marino

  1. 1

    You call and describe the situation

    Call (323) 997-8867 and tell us the make, model, and year of the vehicle, where it is parked, and whether you have any working key. We will ask a few questions to understand whether you need a copy, a replacement for a lost key, or a repair for a broken one.

  2. 2

    We come to your vehicle

    Because we are fully mobile, we travel to you, whether that is a driveway off Del Mar Avenue, a street near Lacy Park, or a lot near the Mission District on Huntington Drive. We do not give arrival-time promises we cannot keep, but we are available 24/7.

  3. 3

    Verifying ownership

    Before cutting or programming anything, we confirm that you are the owner or an authorized user. Expect to show identification and some proof tying you to the vehicle, such as registration or insurance. This protects you and every other car owner.

  4. 4

    Cutting the key on site

    If your vehicle uses a traditional cut or a laser-cut key, we cut it from the vehicle's lock information, so no original key is required. A broken key may also need extraction from the lock or ignition before a new one is made.

  5. 5

    Programming and transponder pairing

    Most modern keys contain a transponder chip or a proximity fob that the car must recognize. We program the new key to your vehicle's immobilizer system, and in many cases remove lost keys from the system so a missing key cannot start the car.

  6. 6

    Testing everything before we leave

    We test the key in the door, trunk, ignition or push-button start, and the remote functions where applicable. You should leave with a key that works fully, not just one that turns the lock.

What affects the price

  • Vehicle make, model, and year, since some systems are far more involved to program than others
  • Type of key: a basic cut key, a transponder key, a remote head key, a smart proximity fob, or a laser-cut key
  • Whether you have a working key to copy or all keys are lost, which can change the amount of work involved
  • Whether a broken key must first be extracted from the ignition or door lock
  • Number of keys needed and whether old lost keys should be erased from the vehicle's system
  • Time of day and location of the vehicle, as after-hours service and travel can affect the final quote

Why San Marino chooses us

  • Fully mobile service means nothing about your car has to move; we bring the cutting and programming equipment to you
  • Operating since 1987 gives us decades of experience with how vehicle security has changed from simple cut keys to encrypted fobs
  • Owner and lead technician David Shar stands behind the work, so you are not dealing with an anonymous dispatch chain
  • We work with the discretion San Marino households expect, arriving quietly and handling the job without fuss at a private residence
  • We can also address the home side of a lost-key emergency, such as rekeying the locks if a house key was on the same ring as the car key
  • 24/7 availability means a lost key at night after an event does not have to wait until morning

Car Key Replacement across San Marino

San Marino is almost entirely residential, and that shapes how car key calls tend to look here. Many homes in the Huntington Library district and the Lacy Park neighborhood sit on large lots with long driveways, gated entries, and several vehicles per household. A lost fob in these areas often means a car parked behind a gate or in a garage, and we come directly to that spot. In 91108, we also hear from visitors who park near the Huntington Library, Art Museum and Botanical Gardens or spend an afternoon at Lacy Park and then discover a key has gone missing.

Around the Mission District on Huntington Drive, near the commercial blocks by Mission Street, we help drivers who lose keys while running errands or visiting Crowell Public Library. Major routes like Huntington Drive, Sierra Madre Boulevard, San Gabriel Boulevard, Del Mar Avenue, and Los Robles Avenue are familiar ground for our mobile crews, and we can meet you wherever you are parked, including near El Molino Viejo.

Because so many San Marino properties have original mortise hardware, solid-wood doors, and high-security cylinders, a lost car key sometimes comes with a bigger question: was a house key on the same ring? If so, we can rekey the exterior doors and garden gates to a single new key while we are there, so one lost ring does not become a lasting security concern.

Car Key Replacement in San Marino — FAQs

Can you make a car key if I have lost every key?
Yes. In most cases we can cut and program a new key on site without an original. You will need to verify ownership first. Call (323) 997-8867 and tell us the vehicle details.
Do you come to me in San Marino, or do I need to visit a shop?
We are fully mobile and have no storefront. We come to your vehicle, whether it is in a driveway, a garage, or parked near Lacy Park or the Huntington.
Are you available at night or on weekends?
Yes, we are available 24/7. If you are stranded late at night, call (323) 997-8867 and we will help you.
What proof of ownership will I need?
Typically a photo ID plus registration, title, or insurance showing that the vehicle is yours. This step protects owners from theft and is not optional.
Can you replace a key that broke off in the ignition or door?
Often yes. We can extract the broken piece and then cut and program a replacement. The condition of the lock affects how involved the job is.
Will the old lost key still start my car?
Not necessarily. In many vehicles we can erase lost keys from the immobilizer when programming a new one, so a missing key no longer works. Ask us about this when you call.
What if my house key was on the same ring as my car key?
Tell us when you call. We can rekey your exterior doors, and gates if needed, so everything works with one new key. This is common on larger San Marino properties.
How is the price determined?
It depends on your vehicle, the key type, whether any key remains, whether a broken key must be extracted, and the time and location. We will explain the factors when you call (323) 997-8867.
