Losing the only key to your car is stressful anywhere, but in Porter Ranch it tends to happen at inconvenient moments: in a parking lot at The Vineyards at Porter Ranch after dinner, at a trailhead near Limekiln Canyon Park, or in a garage at the end of a long commute up the Ronald Reagan Fwy (SR-118). The car is fine. The problem is that no key means no way to start it, and a tow to a dealer is rarely the easy answer.

Crenshaw Lock Company is a fully mobile locksmith. We have no storefront for you to drive to, because the whole service is built around coming to wherever the vehicle is. Owner and lead technician David Shar has run the business since 1987, and car key work, from older cut-only keys to transponder keys and push-button fobs, is a core part of what we do. We cut the key and program it to your car at the curb or in the driveway.

This page explains how replacement works, what changes the cost, what is specific to Porter Ranch, and the questions people here ask most. If you are stranded right now, call (323) 997-8867 and we will talk through your situation.

How it works in Porter Ranch

  1. 1

    Call and describe the situation

    Call (323) 997-8867 and tell us the make, model, and year of the car, whether you have any working key, and where the vehicle is parked. Whether you are in a driveway off Tampa Ave or a lot on Rinaldi St, we work out the right approach before we head out.

  2. 2

    Verify ownership

    Before making a key for a vehicle, we ask for proof that it is yours, typically a photo ID along with registration or title. This protects you. A locksmith who skips this step is a risk to every car owner.

  3. 3

    Identify the key type

    Modern keys range from simple mechanical keys to transponder keys, remote-head keys, and push-to-start smart fobs. We confirm which your car uses, since that determines the blank, the cutting method, and the programming procedure.

  4. 4

    Cut the key on site

    If your car uses a cut key, we cut it from the vehicle's key code or by decoding the lock, so no original is needed. The work is done with mobile equipment at your vehicle.

  5. 5

    Program and test

    Next we program the new key or fob to the car's immobilizer so it will start the engine. We then test every function: door lock, ignition or push-start, remote buttons, and trunk release if applicable.

  6. 6

    Wrap up and spare advice

    Once everything works, we go over your options for a spare key. Having a second key made is generally much easier while you still have one that works, so we encourage it.

What affects the price

  • Vehicle make, model, and year: some manufacturers use more complex security systems that take more time and specialized equipment to program.
  • Type of key: a basic mechanical key, a transponder key, a remote-head key, and a push-to-start smart fob each involve different parts and different programming work.
  • Whether you have a working key: copying an existing key is usually simpler than creating one from scratch when all keys are lost.
  • Number of keys needed: adding a spare during the same visit is often more efficient than arranging a separate trip later.
  • Time of day and location: after-hours calls and hard-to-reach spots can affect the total, and we explain this when you call.
  • Condition of the lock or ignition: if a worn ignition or damaged door lock prevents the new key from working, that repair is a separate piece of work.

Why Porter Ranch chooses us

  • We are fully mobile and available 24/7, so a late-night lost key in a Porter Ranch parking lot does not wait for business hours.
  • Business since 1987 means a long track record with the lock and key systems found on cars over many decades.
  • Keys are cut and programmed at your vehicle, avoiding a tow to a dealership just to get a replacement.
  • We work even when no original key exists, which is the most common situation for people who call us.
  • We require proof of ownership, and we are upfront about what affects the price before work begins.
  • No storefront means no overhead for a showroom, and our focus stays on getting you back on the road.

Car Key Replacement across Porter Ranch

Porter Ranch sits on the northwest rim of the San Fernando Valley, below the Santa Susana Mountains, in ZIP codes 91326 and 91327. Much of the community is made up of newer master-planned developments, and many residents drive late-model vehicles with transponder keys or push-button fobs, which is exactly the kind of key we program on site. Whether you live in The Oaks of Porter Ranch behind the gates or in Porter Ranch Estates, we come to your driveway or garage.

Life here is car-centered. People commute along Reseda Blvd, Corbin Ave, and Mason Ave, and run errands around The Vineyards / Porter Ranch Town Center area. Keys get lost at the shopping center, at Porter Valley Country Club, or at the trailheads near Aliso Canyon Park and Limekiln Canyon Park. The hillside terrain and open trails mean a key can easily fall out of a pocket, so spare keys are worth considering. Residents of the Renaissance and Sorrento tracts often have multiple vehicles in a household, making spares and fob replacements a practical convenience.

Gated access can add a wrinkle. If you are in a gated community, it helps to let your gate or guard know a locksmith is expected, so we can reach the car without delay. We also handle home lock work in Porter Ranch, but for this visit our focus is simple: get you a working key and get you moving again.

Car Key Replacement in Porter Ranch — FAQs

Can you make a car key in Porter Ranch if I lost all my keys?
Yes. Having no original key is the situation we deal with most often. We cut and program a new key on site once ownership is verified. Call (323) 997-8867 to get started.
Do I need to tow my car to a dealer?
Usually not. We are fully mobile and come to your car, whether in a garage in The Oaks of Porter Ranch or a parking space at The Vineyards. Most replacements are completed right where the vehicle sits.
What proof of ownership do you need?
We typically ask for a photo ID plus registration or title showing the vehicle is yours. This is a standard safeguard and helps protect you from someone else getting a key to your car.
Can you replace a push-button or smart key fob?
In many cases, yes. Smart fobs require specific programming to the vehicle, and capability depends on make, model, and year. Call (323) 997-8867 with your vehicle details and we will tell you what to expect.
Are you available at night and on weekends?
Yes, we operate 24/7. A lost key at a late hour near Rinaldi St or Sesnon Blvd does not have to wait until morning.
How much does a replacement car key cost?
It depends on the key type, vehicle make and year, whether you have an existing key, how many keys you want, and when and where you need service. We explain the factors when you call rather than guessing before we know the details.
Can you get into a gated community in Porter Ranch?
Yes, with a little coordination. Let your gate or guard know to expect us, or give us the entry instructions when you call, and we will meet you at your vehicle.
Should I get a spare key made?
We recommend it. Copying a working key is generally simpler than replacing one after all are lost, and a spare can save you a stressful call down the road.
