Losing a key fob in Santa Clarita is more than an annoyance. Many of us live in a commuter city, with long drives down the I-5 and CA-14 and plenty of errands between Valencia and Canyon Country. When the fob that starts your car goes missing, cracks, or simply stops responding, the day stops with it. A dealership trip often means arranging a tow, and that is the part people most want to avoid.

Crenshaw Lock Company is fully mobile. We have no storefront for you to visit. Instead, our technicians drive to your driveway, your office parking lot, or wherever the car is sitting, and replace and program the fob there. David Shar founded the business in 1987, and the work we do today builds on that long experience with automotive locks and keys.

We handle traditional remote-head keys, flip keys, and push-button-start smart or proximity keys. Whether you have lost every key you own, have one working spare and want another, or need a worn-out fob replaced, we will walk through your options clearly before any work begins and tell you what is realistic for your specific make, model, and year.

How it works in Santa Clarita

  1. 1

    Call and describe the situation

    Reach us at (323) 997-8867 any hour. Tell us the make, model, and year of the vehicle, whether you have any working key, and where the car is parked. This helps us bring the right fob hardware and programming equipment.

  2. 2

    Confirm the vehicle and key type

    Not every fob is alike. Some cars use a simple remote and a transponder key, others use a push-button-start smart key. We confirm which type your vehicle uses and whether a compatible replacement is available, so there are no surprises on arrival.

  3. 3

    Verify ownership

    Before we cut or program anything, we ask for proof that the vehicle is yours, typically a registration or title along with your photo ID. It protects you as the owner and is a standard, responsible part of automotive locksmith work.

  4. 4

    Cut and prepare the replacement

    If your vehicle uses a physical blade or emergency key, we cut it to match. We then prepare the new fob so it can communicate with your vehicle's immobilizer system.

  5. 5

    Program on site

    Using professional programming equipment, we pair the new fob with your vehicle right where it is parked. This is the main advantage of a mobile service: the car never has to be towed anywhere.

  6. 6

    Test every function

    We check that the fob locks and unlocks the doors, operates the trunk or hatch if equipped, and starts the vehicle. If you have other fobs, we confirm they still work too, and we answer any questions about spares.

What affects the price

  • Vehicle make, model, and year, since some manufacturers use more complex security systems than others.
  • Type of key: a basic remote, a flip key, and a push-button-start smart key involve different hardware and programming steps.
  • Whether you have a working key already, because duplicating an existing key is often simpler than creating one from scratch when all keys are lost.
  • Whether a physical emergency blade needs to be cut in addition to programming the electronics.
  • Time of day and location, as after-hours and farther-out service calls differ from daytime visits nearby.
  • Number of fobs needed, since programming a spare at the same visit is often more efficient than a separate trip later.

Why Santa Clarita chooses us

  • Fully mobile service means we come to the car, so you can skip the tow and the trip to a dealership.
  • Open 24/7, including nights, weekends, and holidays, because key problems rarely happen at convenient times.
  • In business since 1987, with owner and lead tech David Shar guiding the standards our work is held to.
  • Straight answers up front: if a fob for your vehicle is not something we can program, we tell you rather than guess.
  • Ownership verification on every job, which protects you against someone else getting a key to your car.
  • We also handle home, gate, and commercial locks, so one call can cover your vehicle and your property.

Key Fob Replacement across Santa Clarita

Santa Clarita is spread across several distinct areas, and our mobile service reaches them all. We regularly help drivers in Newhall and Old Town Newhall, where a lost fob might follow a day at a street event, as well as in Saugus, Canyon Country, Valencia, and the newer Plum Canyon developments. ZIP codes we serve include 91321, 91350, 91351, 91354, 91355, 91387, and 91390.

Fob trouble shows up in places typical of the area. A driver may be stuck in a lot at Westfield Valencia Town Center after a shopping trip, a student may have misplaced a smart key near College of the Canyons, or a family might lose a fob during a day at William S. Hart Park or Six Flags Magic Mountain. With a mobile service, we meet you at the vehicle rather than asking you to bring it to us.

Much of Santa Clarita is made up of HOA-governed tract neighborhoods and gated communities with attached two-car garages, where cars are often parked in driveways or garages. We can work in those settings, and if you also need gate fob or keypad help at your community, or a rekey on a new home, just mention it when you call (323) 997-8867. Major routes like Soledad Canyon Rd, Bouquet Canyon Rd, Valencia Blvd, Newhall Ranch Rd, and Sierra Highway help us reach you across the valley at any hour.

Key Fob Replacement in Santa Clarita — FAQs

Can you replace a key fob if I have lost all of my keys?
In many cases, yes. Depending on the vehicle, we can program a new fob even when no working key remains. Call (323) 997-8867 with your make, model, and year and we will tell you what is possible for your car.
Do I need to tow my car to you?
No. We are fully mobile, so we come to your vehicle anywhere in Santa Clarita and program the fob on site. There is no storefront to visit.
What kinds of fobs can you program?
We work with remote-head keys, flip keys, and push-button-start smart or proximity keys for many vehicle makes. Compatibility varies by model and year, so it is best to call and confirm.
What do I need to show to prove the car is mine?
We typically ask for your photo ID plus the vehicle registration or title. This is a standard safeguard that keeps your vehicle secure.
Is key fob replacement available at night or on weekends?
Yes. We operate 24/7, including holidays. If you are stranded late at night in Valencia, Saugus, or anywhere else in the city, call (323) 997-8867.
Can you just fix my fob instead of replacing it?
Sometimes the issue is simply a dead battery or a worn case, and we can tell you if that is the cause. If the electronics are damaged or the fob has lost pairing, replacement and reprogramming may be the better option.
How is the cost of a replacement fob determined?
Price depends on factors like your vehicle's make and year, the type of fob, whether you still have a working key, and whether a blade needs cutting. We explain these factors on the phone so you know what to expect.
Should I get a spare fob while you are there?
It is a good idea. Programming a spare during the same visit is usually more convenient than starting from zero after losing your last key. Ask us about it when you call.
