Losing a key fob is a different kind of problem from losing a plain metal key. The fob is a small radio transmitter, often paired to an immobilizer, and a dealership tow is the usual assumption when nothing else is on the table. In a spread-out city like Simi Valley, where most of us depend on a car to get to work, school, or over the hill on the 118, being stranded without a working fob can derail the whole day.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and we are fully mobile. There is no storefront to visit. Our technician drives to you, whether your car is in a driveway in Wood Ranch, a parking space at the Simi Valley Town Center, or at the curb on a quiet street in Texas Tract, and we work on the vehicle where it sits.

This page explains how fob replacement works, what affects the cost, and what to have ready when you call. We do not quote prices here because the right answer depends on your vehicle, and we would rather give you an honest figure after hearing the details than a number that does not apply to your car.

How it works in Simi Valley

  1. 1

    Tell us the vehicle and the situation

    When you call (323) 997-8867, we ask for the make, model, and year, and whether you have any working key left. A spare changes the job considerably, since copying from a working key is often simpler than creating a first key when all are lost.

  2. 2

    Confirm ownership

    Before cutting or programming anything, we ask for proof that the car is yours, typically a photo ID along with registration or title. This protects you and is a standard, responsible practice.

  3. 3

    Identify the right fob or smart key

    Fobs vary by frequency, chip type, and button layout, and a lookalike will not necessarily pair. We determine the correct part for your specific vehicle so you are not paying for something that will not work.

  4. 4

    Cut the blade if your key needs one

    Many fobs include an emergency blade for the door. If yours does, we cut it on site so the mechanical key works along with the remote.

  5. 5

    Program the fob to the vehicle

    We connect to the car's onboard system and pair the new fob so it starts the engine and operates the remote functions. Where it applies, we can also remove a lost fob from the car's memory so it can no longer be used.

  6. 6

    Test everything before we leave

    We try the lock, unlock, trunk, and start functions, and check proximity entry on smart keys, so you drive away confident rather than discovering a problem later.

What affects the price

  • Vehicle make, model, and year, since some brands use more complex security systems than others
  • Type of key: a basic remote fob, a flip key, or a push-to-start smart proximity key
  • Whether you have a working key to copy or all keys are lost, which affects the programming steps involved
  • Whether the original fob needs a cut emergency blade in addition to remote programming
  • Whether you need a new fob or just reprogramming of an existing one that has lost its pairing
  • Time of day and location of the vehicle, as we operate around the clock and travel to you

Why Simi Valley chooses us

  • Fully mobile service: we come to your car in Simi Valley instead of requiring a tow to a shop
  • Open 24/7, so a lost fob at night or on a weekend does not have to wait until business hours
  • In business since 1987 under owner and lead technician David Shar
  • Straightforward guidance on whether a replacement, a reprogram, or a spare is the sensible choice for your situation
  • We test every function before finishing, rather than only checking that the engine starts

Key Fob Replacement across Simi Valley

Simi Valley's layout makes mobile service particularly practical. Residents in Wood Ranch and Big Sky often park in garages and driveways within gated or semi-gated communities, while people in Bridle Path and Texas Tract frequently park on the street or in a driveway. Wherever the car is, in ZIP codes like 93065 or 93063, we can work there without you having to move a vehicle that will not start.

Fob trouble tends to show up at inconvenient places: a shopping trip at the Simi Valley Town Center, a visit to the Ronald Reagan Presidential Library & Museum, a walk through Corriganville Park or Rancho Simi Community Park, or a hike near the Santa Susana Pass State Historic Park. If a fob is lost or stops working while you are out, call us and we will discuss options for getting you moving again.

Commuters along SR-118, SR-23, Madera Rd, and Tapo Canyon Rd rely on their vehicles daily, so a missing key is more than an annoyance. We serve homes and businesses across ZIP codes 93062, 93063, 93064, 93065, and 93094, and can help with household or storefront lock needs as well, such as a rekey after a tenant move-out or storefront hardware along Cochran St.

Key Fob Replacement in Simi Valley — FAQs

Can you replace a key fob if I have lost every key to my car?
Often, yes. An all-keys-lost situation takes more steps than copying from a working key, but a mobile technician can usually handle it at your vehicle. Call (323) 997-8867 with your make, model, and year and we will tell you what to expect.
Do I need to tow my car to a dealership in Simi Valley?
In many cases you do not. Because we are fully mobile, we come to the car and program the fob on site. Some vehicles have unusual requirements, and we will be upfront if yours is one of them.
How much does a replacement fob cost?
It depends on the vehicle, the type of key, and whether you have a spare. Rather than guess, we give a figure after hearing your details. Call (323) 997-8867 to describe your car.
Do you work at night or on weekends?
Yes. We operate 24 hours a day, 7 days a week, so a lost fob in the evening or on a holiday weekend can still be addressed.
What do I need to show before you program a new fob?
We ask for proof of ownership, usually a photo ID plus registration or title. This is a standard safeguard that keeps your vehicle secure.
Can a fob that stopped working be fixed instead of replaced?
Sometimes. A fob that has lost its pairing may only need reprogramming, and a dead battery is another common cause. We can help figure out which problem you have so you do not pay for a replacement you do not need.
Will my lost fob still be able to start the car?
Where the vehicle allows it, we can erase lost keys from the car's memory during programming, so a missing fob cannot be used. Ask us about this when you call (323) 997-8867.
Do you handle smart keys and push-to-start systems?
Yes. We replace and program smart proximity keys as well as standard remote fobs. The details depend on the vehicle, so tell us the make, model, and year when you call.
