Losing a key fob is a different kind of problem than losing a house key. The car may not start, the doors may not respond, and the dealership may be across the Valley with a waiting list for a tow. In Chatsworth, where so many drivers commute along the Ronald Reagan Freeway or head up Topanga Canyon Boulevard, a dead or missing fob can strand you in a parking lot, a driveway, or a trailhead.

Crenshaw Lock Company is fully mobile. There is no shop to drive to; we bring the equipment to wherever the vehicle is parked, whether that is a ranch-style home off Devonshire Street, a warehouse lot near Lassen and Prairie, or the commuter lot at the Chatsworth Transportation Center. We have served Greater Los Angeles and Ventura County since 1987, and owner David Shar leads the work.

We replace and program remote key fobs, flip-style remotes, and push-button-start smart or proximity keys. That includes a spare when you still have one working fob, a full replacement when you have none, and reprogramming when a fob has stopped talking to the car after a battery change or water exposure.

How it works in Chatsworth

  1. 1

    Call and describe the vehicle

    Phone (323) 997-8867 and tell us the make, model, and year, plus whether you still have any working key. We are available 24/7, so the call can happen at night or on a weekend. We will ask where the car is parked so we can plan the visit.

  2. 2

    Confirm ownership

    Before cutting or programming anything, we ask for proof that the vehicle is yours, such as registration and a matching photo ID. This protects you and is a standard part of responsible automotive locksmith work.

  3. 3

    Identify the correct fob

    Many models use different fob types depending on trim level and production date. We verify the vehicle details and match the right frequency, chip type, and button layout so the replacement works the first time.

  4. 4

    Cut a blade if needed

    If your fob includes an emergency key or a flip key blade, we cut it on site from the vehicle's code or by other approved methods, so the mechanical key works in the door and ignition where applicable.

  5. 5

    Program to the vehicle

    We connect diagnostic programming equipment to the car and register the new fob. If an old lost fob is a concern, it can often be removed from the vehicle's memory so it no longer works.

  6. 6

    Test everything before we leave

    We test lock and unlock, trunk or hatch release, remote start where equipped, and push-button ignition. You get working keys in your hand before the job is finished.

What affects the price

  • Vehicle make, model, and year, since some brands use far more complex security systems than others
  • Type of fob: basic remote, flip key, or smart proximity key with push-button start
  • Whether you have a working key to copy or all keys are lost, which changes the programming steps
  • Whether an emergency blade must be cut or a transponder chip must be cloned or registered
  • How many fobs you need programmed in one visit
  • Time of day and the location of the vehicle, since we are mobile and available around the clock

Key Fob Replacement across Chatsworth

Chatsworth sits in the far northwest corner of the San Fernando Valley against the Santa Susana Mountains, and the places people park here vary a lot. In the Indian Hills and Santa Susana Pass area, a driver might lose a fob on a trail near Santa Susana Pass State Historic Park or after a visit to Stoney Point Park, where climbers and hikers often carry keys in pockets and packs. A fob that goes missing in rocky terrain is a common call, and we can meet you wherever the car is parked.

The Chatsworth industrial and business district around Canoga, Prairie, and Lassen has its own pattern. Fleet vehicles, work trucks, and employee cars sit in large lots all day, and a lost or failing fob can hold up a shift. We can program replacements on site so the vehicle does not need to be towed. In the equestrian horsekeeping district, owners often drive trucks that pull trailers, and a fob dropped in a barn or paddock is easy to lose. We come to the property, including gated lots.

Whether you are in ZIP 91311 near Devonshire Street and Topanga Canyon Boulevard, or in 91313, our service is the same: a mobile technician, no storefront trip, and working keys before we leave. Call (323) 997-8867 any time.

Key Fob Replacement in Chatsworth — FAQs

Can you replace a key fob if I have lost every key?
In many cases, yes. All-keys-lost situations take more steps, but we can often program a new fob on site in Chatsworth. Call (323) 997-8867 with your vehicle details and we will tell you what is possible.
Do I need to bring my car anywhere?
No. Crenshaw Lock Company is fully mobile and has no storefront. We come to your vehicle, whether it is at home, at a business, or at a trailhead near Santa Susana Pass.
Is a locksmith fob replacement different from going to the dealer?
The result is a programmed, working fob, but we travel to you instead of requiring a tow or a trip across the Valley. Availability and compatibility depend on the vehicle, so describe yours when you call.
Will my lost fob still be able to open my car?
Often we can erase lost fobs from the vehicle's memory during programming so only the keys you hold will work. This depends on the make and model, and we can confirm when you call.
Can you program a fob I bought online?
Sometimes. Fobs must match the vehicle's frequency and chip type, and used or mismatched units may not program. If you already have one, tell us the details when you phone (323) 997-8867 and we will advise before the visit.
What proof of ownership do you need?
We typically ask for registration or title and a matching photo ID. This is standard and keeps your vehicle secure.
Can you help with a work truck or fleet vehicle in the industrial district?
Yes. We can program fobs for vehicles parked at warehouses and business lots along Lassen, Prairie, and Canoga, and we can also help with commercial locks at the same location.
What if my fob just stopped working?
A weak battery is the first thing to check, but water damage, a worn case, or lost programming can also be the cause. We can diagnose it and either reprogram or replace it. Call (323) 997-8867 for help at any hour.
