Losing a car key is stressful anywhere, but in Altadena it has its own flavor. You may have parked at the Sam Merrill Trailhead below the Cobb Estate and come back to find the key gone from your pocket. You might be at Farnsworth Park for an evening event, or in a driveway on a steep foothill street where towing is a hassle. Our service is built for those moments: we come to you, and the work happens at your vehicle.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, led by owner and lead technician David Shar. We are mobile only, with no storefront to visit, which means no tow to a shop and no waiting for a dealership appointment. We cut the key blade, program the transponder or smart key to your vehicle, and test it before we finish.

Many Altadena households are also in a period of upheaval after the January 2025 Eaton Fire. Some residents are living in temporary housing, driving vehicles that were exposed to smoke and ash, or have spare keys that were lost with a home. If your only keys burned or went missing during the displacement, a replacement made from scratch is often possible. Whether it is a basic key, a transponder key, a remote head key, or a push-button smart key, we can talk through your options by phone and explain what your specific vehicle needs.

How it works in Altadena

  1. 1

    Call and describe your situation

    Reach us at (323) 997-8867, any time of day or night. Tell us the make, model, and year, where you are in Altadena, and whether you have any working key at all. This helps us bring the right blanks and equipment.

  2. 2

    Confirm ownership

    Before we make a key for a vehicle, we need reasonable proof it is yours. That typically means a photo ID plus registration or title. This protects you and keeps keys from landing in the wrong hands.

  3. 3

    Identify the key type

    Vehicles differ widely. Some use a plain mechanical key, others a transponder chip, a remote head key, or a proximity smart key. We identify what your vehicle uses and explain what is involved.

  4. 4

    Cut the key on site

    When a blade is needed, we cut it at your location, using the vehicle's lock or key code information as appropriate. No towing to a shop is required.

  5. 5

    Program and test

    We program the new key to the vehicle so it starts the engine, and pair remote functions where supported. We then test the door, ignition, and remote buttons before we consider the job done.

  6. 6

    Spare key and next steps

    Once a working key exists, we suggest making a spare while we are there. We also discuss whether any old lost keys should be removed from the vehicle's memory for security.

What affects the price

  • The type of key your vehicle uses: a basic metal key, transponder key, remote head key, and smart key each involve different parts and programming effort.
  • Make, model, and year, since some manufacturers need more involved procedures or specialized equipment than others.
  • Whether you have any existing key to copy from, or whether we must create the first key from scratch.
  • How many keys you want made, since a spare made during the same visit is usually more efficient than a separate trip later.
  • Time of day and your location, as after-hours and hard-to-reach spots can affect the overall quote.
  • Whether remote functions, trunk release, or other add-on features need to be paired in addition to the starting function.

Why Altadena chooses us

  • Fully mobile and available 24/7, so a lost key at a trailhead or late-night parking spot does not have to mean a tow.
  • In business since 1987 and led by owner David Shar, so the work comes from long experience rather than a rotating call center.
  • Keys cut and programmed on site, including all-keys-lost situations where no original is available.
  • No storefront, which keeps things straightforward: we come to you instead of asking you to come to us.
  • We explain the process and the pricing factors before starting, so there are no surprises about what is being done to your vehicle.
  • We verify ownership every time, a step that protects Altadena drivers from unauthorized key duplication.

Car Key Replacement across Altadena

Altadena stretches across the foothills below the San Gabriel Mountains, and a lost key can happen in many different settings. Hikers leave cars near the Sam Merrill Trailhead by the Cobb Estate, families park around Charles White Park and Farnsworth Park, and commuters run daily along Lake Ave, Lincoln Ave, Fair Oaks Ave, Altadena Dr, and Woodbury Rd. We serve all of it, including ZIP codes 91001 and 91003, wherever your vehicle is stuck.

Neighborhood driveways can be tricky. In Janes Village, with its Craftsman bungalows and narrow lots, cars often sit curbside or in older detached garages. Around Christmas Tree Lane on Santa Rosa Avenue, the Altadena Country Club area, and The Meadows, hillside driveways and gated entries are common. Because we work at the vehicle itself, we can usually handle these setups without you moving the car.

The Eaton Fire changed daily life here, and we know that many people are still sorting out their belongings. If your car keys were lost when a house was damaged, or you are driving a vehicle that has been through smoke and ash exposure and the key or ignition feels sluggish, tell us when you call. We can look at the situation, make a new key where possible, and give you a working set so you have one less thing to worry about. Call (323) 997-8867 anytime.

Car Key Replacement in Altadena — FAQs

Can you make a car key in Altadena if I have no original key?
Yes, in most cases. We can create a new key even when all keys are lost, depending on the vehicle. Call (323) 997-8867 with your make, model, and year and we will tell you what is involved.
Do I need to tow my car to you?
No. We are fully mobile and have no storefront. We cut and program the key at your vehicle, whether it is in a driveway, at a park, or on the street.
Are you really available 24/7?
Yes. Crenshaw Lock Company takes calls around the clock. You can reach us at (323) 997-8867 at night, on weekends, and on holidays.
What proof of ownership do I need?
Generally a photo ID along with registration or title showing the vehicle is yours. We ask for this every time to protect vehicle owners.
How is the price determined?
It depends on the key type, vehicle make and model, whether an original key exists, how many keys you want, and when and where we are called out. We explain these factors before work starts.
Can you replace a smart key or push-button start fob?
For many vehicles, yes. Smart keys require specific programming, so please call (323) 997-8867 with your vehicle details to confirm what we can do for your model.
I lost my keys during the Eaton Fire displacement. Can you help?
We can often make new keys even when originals are gone. Bring proof of ownership if you can, such as ID and registration or title, and we will work through the options with you.
Should I get a spare made at the same time?
We recommend it. Making a spare during the same visit is usually more efficient than a second call later, and it keeps you from facing the same problem again.
