Losing a key fob, or having one stop working, tends to happen at bad moments: after a visit to the Mission San Fernando Rey de Espana grounds, in the parking lot of a medical office, or in the driveway on a weekday morning. Modern remotes and smart keys are small computers, and replacing one is more than cutting metal. The new fob has to be matched to your vehicle's immobilizer system, and in many cases the lost one should be removed from the car's memory so it can't be used.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, led by owner and lead technician David Shar. We are fully mobile and available around the clock. There is no storefront to drive to, which matters most when the reason you need us is that your car won't start or unlock the way it should.

This page explains how fob replacement works, what influences the cost, and what Mission Hills drivers should know. If you're unsure whether you need a new fob, a new battery, or reprogramming, call (323) 997-8867 and describe what the key is doing. Sometimes the fix is simpler than a full replacement.

How it works in Mission Hills

  1. 1

    Tell us about the vehicle

    When you call (323) 997-8867, we ask for the make, model, and year, what type of key you have (a flip key, a push-button remote, or a push-to-start smart key), and whether you still have any working key. That determines what hardware and equipment the job needs.

  2. 2

    We come to you

    Because we are fully mobile, the work happens where the car is parked: a driveway on a quiet residential street, a spot along Brand Boulevard, or a lot near Providence Holy Cross Medical Center. You don't have to tow the car or arrange a ride.

  3. 3

    Verify ownership

    Before we create or program a key, we confirm that you are the rightful owner or authorized user of the vehicle. This protects you and is a standard practice for responsible automotive locksmiths.

  4. 4

    Prepare and program the new fob

    We provide a replacement fob suited to your vehicle, cut the emergency blade if the design has one, and program the remote functions and the immobilizer link using professional equipment. Depending on the vehicle, this can include adding a key when no working key remains.

  5. 5

    Remove lost keys when appropriate

    If the old fob is lost or stolen, we can often erase it from the vehicle's memory so that only the keys you hold will start the car. Capabilities vary by make, so we explain what is possible for your vehicle.

  6. 6

    Test everything before we leave

    We test lock and unlock, trunk or hatch release, panic function, and starting the engine, plus the emergency blade if included. You leave knowing every function works.

What affects the price

  • Vehicle make, model, and year, since some systems are far more involved to program than others
  • Type of key: a basic remote, a flip key, or a push-to-start smart key all involve different parts and procedures
  • Whether you have a working key to copy from or all keys are lost, which can change the programming steps required
  • Whether the fob needs a cut emergency blade in addition to the electronic components
  • How many replacement fobs you need, and whether lost ones should be removed from the car's memory
  • Time of day and location, since we serve 24/7 and the job may be an urgent after-hours call

Key Fob Replacement across Mission Hills

Mission Hills sits in the northeast San Fernando Valley, and its car habits reflect that. Residents in the Historic Mission district and in the Dennis Park tract park in driveways and on quiet streets of late-1940s to 1960s stucco ranch and minimal-traditional homes, while the Sepulveda Boulevard corridor mixes shoppers, commuters, and business traffic. A fob that dies or goes missing in any of those places is easy for us to reach, since we come to you in ZIP code 91345 and the surrounding area.

Drivers here often split time between local errands and freeway trips on CA-118 (the Ronald Reagan Freeway), so a key that fails away from home is a real inconvenience. Visitors to Mission San Fernando Rey de Espana, the Andres Pico Adobe, or the San Fernando Mission Cemetery sometimes call us after discovering a lost fob in a parking area they don't know well. Staff and visitors at Providence Holy Cross Medical Center and the nearby medical offices have similar needs, often during a busy shift.

If you also have a home in Mission Hills, we can help with the locks too, such as rekeying a mid-century ranch home after a purchase or addressing an aging lockset near the Mission. For your vehicle, call (323) 997-8867 any hour and we'll talk through the next step.

Key Fob Replacement in Mission Hills — FAQs

Can you replace a key fob if I've lost all my keys in Mission Hills?
In many cases, yes. We can often create and program a new fob even when no working key remains, depending on the vehicle. Call (323) 997-8867 with the make, model, and year and we'll tell you what's possible.
Do I need to tow my car to you?
No. We are fully mobile, so we come to your vehicle, whether it's at home near Dennis Park, along Sepulveda Boulevard, or in a lot near the medical center. There is no storefront to visit.
Is it a dead battery or a failed fob?
Often it's just the battery, particularly if the remote range has been shrinking. If a battery swap or reprogramming resolves it, we'll say so. If the fob is damaged or missing, replacement is the next step.
Can you program a push-to-start smart key?
We replace and program remote key fobs and smart or proximity keys. Feasibility depends on the vehicle, so call (323) 997-8867 and tell us the details before we head out.
Will my lost fob still work after you program a new one?
Where the vehicle allows it, we can erase lost keys from the car's memory so they no longer start it. We'll explain what applies to your make and model.
Are you available at night or on weekends?
Yes. Crenshaw Lock Company is available 24/7. We don't make timing promises, but you can call (323) 997-8867 at any hour to get started.
What do you need from me to start?
We need the vehicle's make, model, and year, plus the type of key you have. We also verify that you own or are authorized to use the vehicle before creating or programming a key.
What affects the cost of a replacement fob?
Mainly the vehicle, the key type, whether any working key remains, whether a cut blade is needed, and how many fobs you want. After-hours service can also play a part. We explain the factors before starting work.
