A dead or missing key fob rarely picks a convenient moment. In Lancaster it might happen in a parking lot near The BLVD after a show at the Performing Arts Center, in a driveway in Quartz Hill, or at a gas stop along the Antelope Valley Freeway. The fob is not just a button pad. It carries a transponder chip and often a rolling-code radio that your car has to recognize, which is why a hardware-store copy usually does not work.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and owner and lead technician David Shar has watched fobs evolve from simple remotes into encrypted smart keys. We are fully mobile. There is no storefront to visit and no tow required. We bring the equipment to wherever the vehicle is parked, and we are available around the clock.

This page explains how replacement works, what influences the price, and what to expect with the vehicles common in the Antelope Valley, so you can make a calm decision even when the situation is stressful. Whether you need a spare before a long drive out of the valley or a replacement after losing your only key, we can walk you through the options by phone at (323) 997-8867.

How it works in Lancaster

  1. 1

    Call and describe the vehicle

    Tell us the make, model, and year, and whether you have any working key left. Having the VIN or registration handy helps. We will explain what type of fob your car uses and whether on-site programming is realistic for it.

  2. 2

    We come to your location

    Because we are fully mobile, we meet you where the car is, whether that is a driveway in West Lancaster, a lot near the Antelope Valley Fairgrounds, or the roadside. We do not make arrival-time promises we cannot verify, but we are available 24/7.

  3. 3

    Verify ownership

    Before cutting or programming anything, we ask for photo ID and proof the vehicle is yours, such as registration or title. This protects you and is standard practice for responsible automotive locksmiths.

  4. 4

    Cut the blade and prepare the fob

    If the fob has an emergency key blade, we cut it to your vehicle's code. For many vehicles we can cut a key even when all originals are lost. Smart keys typically use an emergency blade hidden inside the fob.

  5. 5

    Program to the vehicle

    We connect diagnostic programming equipment to the car, register the new fob, and where needed remove lost fobs from memory so a missing one can no longer start the vehicle.

  6. 6

    Test everything

    We test lock, unlock, trunk, panic, remote start if equipped, and starting the engine. You leave with working fobs and an understanding of how to care for them.

What affects the price

  • Vehicle make, model, and year, since newer smart keys and some brands require more involved programming than older remote-head keys.
  • Fob type: a basic remote with a blade, a flip key, and a proximity smart key all differ in parts cost and programming steps.
  • Whether you have a working key to copy from or all keys are lost, which can change the procedure required.
  • Number of fobs needed, including a spare, and whether old lost fobs should be erased from the car's memory.
  • Time of day and your location within the service area, since we operate 24/7 and travel to you.
  • Whether the fob is OEM or a quality aftermarket unit, which affects part cost and features such as remote start buttons.

Why Lancaster chooses us

  • Fully mobile service since 1987: we do the work at your vehicle, so you never have to tow a car to a shop.
  • Owner-led experience: David Shar has been in the trade for decades and brings that background to modern fob and transponder work.
  • 24/7 availability, including nights and weekends, for the lockouts and lost-key moments that do not wait for business hours.
  • Honest guidance: if your fob only needs a battery or a re-sync, we will say so rather than sell you a replacement.
  • Ownership verification on every job, so a key is only made for the person who can show the vehicle is theirs.
  • Lost fobs can be removed from the car's memory, which matters if a key went missing in a public place.

Key Fob Replacement across Lancaster

Lancaster is a car-dependent city. Residents commute along CA-14, run errands on Sierra Highway, and cover long stretches of the Avenue J, K, and L grid, so a car that will not start or lock is a real disruption. We help drivers across ZIP codes 93534, 93535, and 93536, from the older bungalows around The BLVD to the stucco two-story tract homes of East Lancaster and West Lancaster.

The valley's mix of activity creates its own fob stories. Visitors heading to the Antelope Valley California Poppy Reserve in bloom season sometimes lose a fob on a trail or in a field. Pilots and staff near the Fox Field area, shoppers heading toward the Antelope Valley Mall in nearby Palmdale, and fairgoers at the Antelope Valley Fairgrounds all park for hours, and a fob lost in the crowd can leave a car stranded. Desert heat is also hard on plastic cases and batteries, and a fob left in a hot car often fails sooner than expected.

We also work with renters and property managers in Quartz Hill and near downtown, where a fob can go missing during a move or turnover. If you are in Lancaster and need a fob replaced or a spare made, call (323) 997-8867 and we will come to you.

Key Fob Replacement in Lancaster — FAQs

Can you replace a key fob if I lost all my keys in Lancaster?
In many cases, yes. We verify ownership, cut a blade to the vehicle's code where applicable, and program a new fob on site. Call (323) 997-8867 with your vehicle details and we will tell you what is possible for your car.
Do I need to tow my car to have a fob programmed?
Usually not. We are fully mobile and bring the programming equipment to your vehicle, whether it is at home in Quartz Hill, at work, or on the roadside.
Is it cheaper to buy a fob online and have you program it?
Sometimes, but it carries risk. Online fobs can be the wrong frequency, locked to another vehicle, or low quality. Ask us before buying, and we can tell you whether a specific fob will work with your car.
What price should I expect?
Price depends on your vehicle, the fob type, whether you have a working key, and how many fobs you need. We do not quote generic numbers here, but call (323) 997-8867 with your details and we will explain the factors for your car.
Will my old lost fob still work after replacement?
We can erase lost fobs from the vehicle's memory during programming on many models, so a missing key can no longer operate the car. Let us know if that is a concern.
What proof of ownership do you need?
Photo ID plus something that ties you to the vehicle, such as registration or title. This is a standard safeguard and applies to every job.
My fob just stopped working. Do I need a new one?
Not always. A weak battery, worn buttons, or a lost sync are common causes. We can diagnose it and tell you honestly whether a battery or reprogram will do the job.
Are you available at night or on weekends in Lancaster?
Yes. We operate 24/7 and are fully mobile. Call (323) 997-8867 any time and we will help you get started.
