A key fob is easy to take for granted until it is gone. In Irwindale, that moment tends to happen in a work setting: a driver finishes a shift at a plant near the I-605 and Arrow Hwy interchange, a contractor comes out of a quarry yard off Irwindale Ave, or someone leaves the Santa Fe Dam Recreation Area to find the remote missing from a pocket. The car may be fine, but without a working fob you can't lock it, can't start it, or can't trust it.

Crenshaw Lock Company is fully mobile. We have no storefront, so there is nowhere to tow your car to. We come to you with the equipment to cut, pair, and program replacement fobs and proximity keys on site. Owner and lead technician David Shar has run the business since 1987, and that history with automotive locks and electronics shapes how we approach every job.

This page explains how a replacement works, what affects the cost, and what is specific to Irwindale. A small town with a large industrial footprint means many of our calls involve fleet vehicles, work trucks, and employee cars, along with the everyday needs of residents in the older townsite homes.

How it works in Irwindale

  1. 1

    Tell us about the vehicle

    Call (323) 997-8867 and give us the make, model, and year, plus whether you have any working key left. We'll explain what type of fob your car uses, whether it's a basic remote, a flip key, or a push-button-start smart key, and what the job involves.

  2. 2

    We travel to your location

    Because we're mobile and available around the clock, we meet you where the car is: a plant parking lot, a driveway in the original townsite, a gravel-lot entrance, or a roadside near the Foothill Freeway. Nothing needs to be towed.

  3. 3

    Verify ownership

    Before creating a new key for any vehicle, we confirm you are the owner or authorized user. This protects you and is standard practice for responsible automotive locksmiths. Have your ID and registration or other proof handy.

  4. 4

    Cut and prepare the new fob

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

  5. 5

    Program and pair

    We connect programming equipment to the vehicle and register the new fob so it starts the engine and operates the locks, trunk, and any other remote functions your model supports. If you have older fobs, we can often keep them working or remove a lost one from the car's memory.

  6. 6

    Test everything before we leave

    We try every function: lock, unlock, start, trunk or hatch, and panic where applicable. You leave with a fob that works, and we answer any questions about spare keys or battery care.

What affects the price

  • Fob type: a basic remote, a transponder flip key, and a push-button smart key differ in hardware and in how much programming work they require.
  • Vehicle make, model, and year: some manufacturers use more involved security systems than others, which affects the programming steps.
  • Whether you have a working key: adding a copy from an existing key is generally simpler than creating the first key when all keys are lost.
  • Key cutting needs: a fob with an emergency or blade key requires cutting, while a pure proximity key may not.
  • Time of day and location: since we're available 24/7 and travel to you, after-hours calls and remote locations can influence the final quote.
  • Number of fobs: programming more than one at the same visit, such as a spare for a fleet or family car, can change the overall scope.

Why Irwindale chooses us

  • Fully mobile since 1987: we've been working on vehicles in the Los Angeles area for decades, and every job happens at your car.
  • Owner involvement: David Shar leads the work, so you aren't handed off to an unknown dispatcher process.
  • Open 24/7: a lost fob after a late shift or an event at the Speedway doesn't have to wait until morning.
  • Straight answers up front: we describe what your vehicle needs and what affects the price before work begins, with no invented promises.
  • Practical for fleets and work vehicles: we understand the needs of businesses around Irwindale that depend on trucks and employee cars being drivable.
  • No storefront runaround: you won't be asked to come to a shop, because there isn't one. We come to you.

Key Fob Replacement across Irwindale

Irwindale is a small city with an unusual layout. The original townsite around Irwindale Ave and Los Angeles St holds most of the residential area, with older single-family homes and long-time residents. Across the rest of town, gravel quarries, aggregate pits, distribution centers, food and beverage plants like Huy Fong Foods, and sound stages dominate the land. That mix means a fob problem can come from a family car parked on a quiet residential street or from a work vehicle at the edge of a quarry district near Santa Fe Dam.

We serve the ZIP codes 91706, 91702, and 91010, and the routes people use to get around: the I-210 Foothill Freeway, the I-605 San Gabriel River Freeway, Arrow Hwy, Irwindale Ave, and Live Oak Ave. Whether you're at the Irwindale Metro A Line station after a commute, at the Santa Fe Dam Recreation Area on Arrow Hwy, or at the Irwindale Speedway & Event Center during a busy event, we can come to the vehicle and handle the replacement there.

Industrial surroundings bring their own wrinkles. Dust from quarry work, rough lots, and long shifts are hard on fobs, and drivers often misplace them between sites. If you manage vehicles for an employer here, call (323) 997-8867 and tell us about your fleet. A spare programmed in advance is usually far easier than an emergency replacement.

Key Fob Replacement in Irwindale — FAQs

Do you really come to me in Irwindale?
Yes. Crenshaw Lock Company is fully mobile and has no storefront. We travel to your vehicle anywhere in Irwindale and program the fob there. Call (323) 997-8867 to start.
Can you replace a fob if I've lost every key?
In many cases, yes. An all-keys-lost situation involves more work than copying from an existing key, but we can often create a new key on site. Call us with your vehicle details and we'll tell you what's possible.
Do you handle push-button-start smart keys?
Yes. We replace and program proximity and smart keys as well as traditional remotes and flip keys. Support depends on the make, model, and year, so give us those details when you call (323) 997-8867.
What proof of ownership do I need?
Expect to show a photo ID along with registration, title, or other documentation tying you to the vehicle. We verify ownership before making any new key, which protects you from misuse.
Will my old fob still work afterward?
Often it will, but it depends on the vehicle. If your old fob is lost, we can usually remove it from the car's memory so it no longer works. Ask us about this when we're programming.
Do you serve work vehicles and fleets near the quarries and plants?
Yes. We work on employee cars and many work vehicles around the industrial parts of Irwindale. For fleet needs or spares, call (323) 997-8867 and describe the vehicles involved.
Are you available at night or on weekends?
We are available 24 hours a day, 7 days a week, including nights, weekends, and event days at places like the Irwindale Speedway & Event Center.
Should I try a battery change first?
If your fob works intermittently or its range has dropped, a fresh battery is worth trying. If it's lost, cracked, water-damaged, or unresponsive after a new battery, it likely needs replacement or reprogramming.
