Losing a car key is stressful anywhere, but in Stevenson Ranch it tends to happen at inconvenient spots: a trailhead near Pico Canyon, a parking structure after a day at Six Flags Magic Mountain, or the driveway of a big two-story home when the only fob has vanished into a kid's backpack. Because this is a spread-out, car-dependent community, a dead-end key problem can strand you far from a shop.

That is why we come to you. Crenshaw Lock Company is fully mobile, with no storefront to drive to, and we are available 24/7. We replace lost, broken, or worn car keys by cutting and programming them on site, including situations where there is no original key at all, known as an all-keys-lost situation.

We have served Greater Los Angeles and Ventura County since 1987, under owner and lead tech David Shar. That experience matters with modern vehicles, where a key is often a small computer: transponder chips, remote fobs, and push-button start systems each need to be handled correctly. Here is how it works and what to expect.

How it works in Stevenson Ranch

  1. 1

    Call and describe the situation

    Call (323) 997-8867 and tell us the make, model, and year, and whether you have any working key. Let us know where the car is parked, whether in a driveway in Southern Oaks, a lot near the Old Road, or somewhere else, so we can plan the visit.

  2. 2

    Confirm you own the vehicle

    Before making a key, we verify that the vehicle is yours. Expect to show identification and proof of ownership or registration. This protects you and every other driver, and we do not skip it.

  3. 3

    Get into the car if needed

    If the vehicle is locked, we open it using methods designed to avoid damage to the door, paint, and weather seals. If you are simply missing a key but the car is open, we move straight to key work.

  4. 4

    Cut the key blade

    We cut a new key to fit your ignition and doors. With no original, we can generate the cut from the vehicle itself, so you do not need a dealer tow.

  5. 5

    Program the transponder or fob

    Most vehicles from the past couple of decades will not start without a properly programmed chip. We program the new key to the car's computer and set up remote functions where the vehicle supports them.

  6. 6

    Test everything before we leave

    We test the new key in the ignition, door locks, trunk, and remote buttons. If an old lost key is a theft concern, we can discuss removing it from the car's memory where the vehicle allows it.

What affects the price

  • Vehicle make, model, and year, since some systems are far more complex to program than others.
  • Key type: a basic cut key, a transponder key, a remote head key, a smart key, or a push-button start fob.
  • Whether you have a working original to copy, or it is an all-keys-lost situation requiring more work.
  • Whether the vehicle also needs to be unlocked or has a damaged ignition or lock.
  • Time of day and location of the service call, given that we operate 24/7.
  • The number of keys you need made during the same visit.

  • We handle all-keys-lost situations, not just duplicates of an existing key.

  • We explain what is needed for your specific vehicle and what affects the cost before work begins.

Car Key Replacement across Stevenson Ranch

Stevenson Ranch is a master-planned community of 1990s and 2000s homes, many with multi-car garages, and households here often have several vehicles and several keys in circulation. Whether you are in The Oaks of Stevenson Ranch, Southern Oaks, Pinetree, or Diamondhead, we come to your driveway or street in ZIP code 91381. In gated areas like The Oaks, let us know your gate or guest access setup when you call so we can arrive without delay.

Our calls here follow the way people actually live and drive: commuters heading out on I-5, parents running Stevenson Ranch Parkway, hikers and visitors at Pico Canyon Park and Mentryville, and shoppers near Westfield Valencia Town Center. If you are stuck at one of those spots with no key, we can generally meet you at the vehicle rather than ask you to get somewhere else.

Since we work with homeowners across the community on rekeys and smart-lock installs too, we can also help you coordinate house and car keys if a lost key ring has both. Call (323) 997-8867 any time.

Car Key Replacement in Stevenson Ranch — FAQs

Can you make a car key if I have lost all of my keys?
Yes. All-keys-lost situations are a normal part of our work. We verify ownership, then cut and program a new key at your vehicle in Stevenson Ranch. Call (323) 997-8867 to get started.
Do I need to tow my car to the dealership?
In most cases, no. We are fully mobile and bring cutting and programming equipment to you, which can save the cost and hassle of a tow.
What proof of ownership will I need?
We typically ask for a photo ID plus registration, title, or other proof that the vehicle is yours. This is for your protection and is required before we make a key.
Can you program a push-button start or smart key?
Many models support it. Tell us the make, model, and year when you call (323) 997-8867 and we will confirm what is possible for your vehicle.
Are you available at night or on weekends?
Yes, we are available 24/7. We do not have a storefront, so all service happens at your location.
Will the old lost key still start my car?
On many vehicles we can erase lost keys from the car's memory when programming a new one, so the missing key will no longer start it. Ask us about your specific model.
Can you help if I am locked out and also missing my key?
Yes. We can unlock the vehicle with methods meant to avoid damage, then make and program a new key in the same visit.
What affects the price of a replacement key?
Mainly the vehicle, the type of key or fob, whether you have an original, and whether the car also needs unlocking. We explain the factors for your car before starting.
