A key fob stops working at the worst moments: in the parking lot at The Shops at Montebello with a cart full of groceries, outside a Washington Blvd office after a long shift, or in the driveway before the morning commute onto the I-5. Modern fobs are small computers, and when one is lost, cracked, or unresponsive, you cannot always just cut a new piece of metal and drive away.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and owner and lead technician David Shar has watched vehicle keys evolve from simple cut keys to transponder chips, remote heads, and push-button proximity systems. We are fully mobile. There is no shop to tow your car to and no storefront to visit; we bring the equipment to wherever the vehicle is parked in Montebello.

On this page we explain how a fob replacement works, what changes the cost, and what to expect. Not every vehicle is the same, so we describe things honestly rather than promise one outcome for every make and model. If you are stranded right now, call (323) 997-8867 and we will talk through your situation.

How it works in Montebello

  1. 1

    Call and describe the vehicle

    Tell us the make, model, year, and what happened: lost key, broken fob, dead battery, or a fob that works only some of the time. We will ask whether you still have any working key, since that affects the programming approach. Call (323) 997-8867 at any hour.

  2. 2

    Confirm ownership

    Before we create a new key for a vehicle, we ask for proof that it is yours, such as registration and matching photo ID. This protects you and keeps keys from reaching the wrong hands, and we do not skip it.

  3. 3

    We come to your vehicle

    Because we are fully mobile, we meet you where the car is, whether that is a driveway in North Montebello, a gated lot in Montebello Hills, or a parking space near Grant Rea Park. You do not need to tow the car.

  4. 4

    Check the battery first, then cut or prepare the key

    Sometimes a fob only needs a fresh battery, and we will say so if that is the case. If a replacement is needed, we prepare the correct fob and, when the vehicle uses one, cut the emergency blade or the transponder key.

  5. 5

    Program and test

    We pair the new fob with the vehicle's computer using professional programming equipment, then test lock, unlock, trunk, panic, and start functions. If you have spare or older fobs, we can bring them into the system so everything works together.

  6. 6

    Review what you have

    We walk through how the new fob works, what to do with the remaining keys, and suggest keeping a spare so a future loss does not strand you again.

What affects the price

  • Vehicle make, model, and year, since some brands use far more complex security systems than others
  • Type of key: basic remote, flip key, transponder key, or smart proximity key
  • Whether you still have a working key or all keys are lost, which changes the programming steps required
  • Whether a replacement blade must also be cut or the fob housing and battery only need service
  • Whether you want extra spare fobs programmed during the same visit
  • Time of day and location of the vehicle, since we serve 24/7 and travel to you

  • Available 24/7, including nights, weekends, and holidays
  • Honest answers up front: if only a battery is needed, we tell you instead of selling a new fob

Key Fob Replacement across Montebello

Montebello sits at the crossroads of the I-5 and I-710, and Washington Blvd, Montebello Blvd, and Beverly Blvd carry constant daily traffic. That means vehicles here spend a lot of time in parking lots and on the street: shoppers at The Shops at Montebello, event guests at Quiet Cannon, and families visiting Grant Rea Park or the Juan Matias Sanchez Adobe. A lost or failed fob in any of those places is common, and we can meet you at the vehicle.

At home, Montebello varies. In the older core and North Montebello, many 1920s to 1950s houses have narrow driveways or street-only parking, so the car often sits at the curb. In Montebello Hills, newer hillside homes on the former oil-field slopes often have gated driveways, and a fob can fail right when you need to get in or out. If you are also locked out behind a gate, we can discuss gate hardware and entry locks in the same visit. Residents in Montebello Gardens, just adjacent to the city, are served as well.

Whether your vehicle is parked in ZIP code 90640 or nearby, call (323) 997-8867. We will confirm the details of your vehicle, explain your options, and come to you.

Key Fob Replacement in Montebello — FAQs

Can you replace a key fob if I lost all my keys in Montebello?
In many cases yes. When no working key remains, programming is more involved, but we can often create and program a new fob on-site after verifying ownership. Call (323) 997-8867 with your vehicle details and we will tell you what to expect.
Do I need to tow my car to a dealership?
Often not. We are fully mobile and come to your vehicle in Montebello with the equipment needed. Some unusual vehicles may have limitations, and we will tell you honestly when we know.
My fob stopped working. Does it need replacing?
Not always. A weak battery is a common cause, and sometimes a fob only needs to be reprogrammed. We check the simple fixes first so you do not pay for a new fob you do not need.
Can you program a smart or push-button start key?
Yes, we work with many smart proximity keys. Compatibility depends on make, model, and year, so call (323) 997-8867 and give us your vehicle information.
What proof of ownership do you need?
We ask for your photo ID and documentation showing the vehicle is yours, such as registration or title. This is required for every vehicle key we create.
How is the cost determined?
Price depends on the vehicle, the key type, whether you have a working key, whether a blade needs cutting, and how many fobs you want. We do not guess at figures here; describe your vehicle and we will walk you through it.
Are you available at night or on weekends?
Yes. Crenshaw Lock Company is 24/7 and fully mobile, so you can call any time, including holidays.
Can you make a spare fob while you are here?
Yes. Adding a spare during the same visit is usually easier than doing it after a loss. Mention it when you call so we can plan for it.
